“When I was a mercenary, I rarely got too close to anyone. That all changed when I became a professor.”
—Byleth in Fire Emblem Heroes

Byleth is the main protagonist of Fire Emblem: Three Houses and the secondary antagonist in Fire Emblem Warriors: Three Hopes. As an Avatar, their name, gender, and birthday are customizable. Byleth serves as a professor at Garreg Mach Monastery. They possess the mysterious Crest of Flames and can wield the Sword of the Creator.

Profile[]

Born to Jeralt and Sitri on the 20th of the Horsebow Moon 1159, Byleth lost their mother shortly after their birth. She was buried at Garreg Mach Monastery. Some time after her death, Jeralt left the Knights of Seiros, taking his newborn child with him to travel Fódlan, becoming a mercenary in the process and starting his own mercenary company.

The reason for Jeralt's departure began with the circumstances behind Byleth's birth. Sitri was the twelfth created vessel intended to host the spirit of Sothis through her Crest of Flames. Like her predecessors though, she too was unable to fully merge with Sothis. Sitri eventually fell in love with Jeralt, who had received Seiros' crest when Rhea, Seiros' current alias, gave him her blood after he took a mortal wound in her stead. The union of the vessel and inheritor of a Crest of Seiros resulted in the birth of Byleth. However, Byleth was nearly stillborn with no heartbeat and Sitri was similarly near death. To give her child a chance at life, Sitri pleaded for Rhea to give Byleth her heart. The transplant was a success and Byleth lived, but Sitri died as a result. Mysteriously, though Byleth was in a physically healthy state with a pulse, a doctor noted that they still lacked a heartbeat.

Jeralt's existing suspicions of Rhea grew after this event, especially with Byleth's unusual behavior, neither crying nor laughing as a baby. By Wyvern Moon 1159, Jeralt sought a way to leave Garreg Mach Monastery and the Church of Seiros by any means. Starting a blaze, he used the event to claim that his child had perished in the blaze on the 7th day of the month. Supposedly heartbroken by the deaths of his wife and child, he left the Monastery and secretly took Byleth with him. He formed his own band of mercenaries mainly to mask his movement throughout Fódlan so spies of the Church of Seiros could not easily track him or his child.

During Byleth's childhood, Jeralt shared little information about the world, the Church of Seiros and especially his past. Byleth either forgot or never learned their true birthdate, Jeralt claiming they were born years after the fire to a woman who supposedly died of illness. Jeralt trained Byleth in combat, eventually joining his band of mercenaries and gaining a fearsome reputation for their unflinching courage in battle. They would soon be known as the "Ashen Demon" as a result.

Three Houses[]

Academy Phase[]

In recent times, Byleth has been having dreams of a young green-haired girl; however, when they inquire with Jeralt, he does not know anyone by the same description. Jeralt reminds Byleth that their next job will bring them to the Holy Kingdom of Faerghus, but a sudden uproar occurs when three students from the Officers Academy, Edelgard, Dimitri, and Claude, approach the two, asking for their assistance with bandits who are trying to kill and plunder the trio. The three lords, with the aid of Byleth and Jeralt manage to dispatch most of the bandits when their leader Kostas attempts to kill Edelgard, spurring Byleth to take a blow for her. Just as Byleth is about to die, time freezes and they encounter the green-haired girl once more who chastises them for being reckless. The girl introduces herself as Sothis, a name she just recalled. She and Byleth realize that they can rewind time to prevent Byleth's impending demise. The flow of time reverses, and Byleth is able to push Edelgard out of the way and disarm Kostas, quelling the remaining bandits.

Reinforcements arrive from the Knights of Seiros shortly afterwards and one of its members, Alois, recognizes Jeralt. He invites the two to visit Garreg Mach Monastery, and they comply. Before departing, Byleth converses with the trio from earlier, each impressed by their skill. They extend invitations to join the service of their respective kingdoms and Byleth expresses interest in one of them. Given the journey ahead, the trio get to know Byleth in order to sway them over to their side.

The Archbishop of the Church of Seiros, Rhea thanks Byleth for saving the students. Impressed by their skill, she hires them to become a professor of the students as a vacancy had just opened up. Despite Jeralt's wariness, Byleth accepts the position after Jeralt himself is asked to rejoin the Knights of Seiros. One of Byleth's fellow professors, Hanneman, asks them to use his special device to determine if they hold a crest. To both their astonishment, not only does Byleth have a crest, but it is a crest that has never been seen before.

After taking time to talk to the three house leaders and learning more about the students in each of their houses, Byleth chooses one of them to serve as professor. This choice does not change much of the Academy Phase's storyline as the events of this phase are shared.

As part of their duties, Officer Academy students are given tasks each month by the Church. The first month, the Great Tree Moon has no formal mission for the students, just an annual house mock battle competition between the three houses. Through Byleth's leadership, their class emerges victorious. The Harpstring Moon marks the first formal mission that Byleth's class receives. Tasked with dispatching bandits at Zanado, the battle serves as the first real taste of combat to the students. This battle would mark the beginning of a long string of events behind a greater conspiracy.

The Garland Moon has Byleth's class tasked with quelling a rebellion staged by members of the Western Church who have begun rebellion against the Church of Seiros. Byleth's class faces off against one of the rebellion's leaders, Lord Lonato in a misty forest. The battle ends with Lonato's death.

During the Blue Moon, defectors of the Western Church invade the Holy Mausoleum in order to steal the holy corpse of Seiros. Though the Death Knight, a mysterious yet powerful knight, is among their forces, he does not fight alongside them and retreats when most of them are defeated, leaving the leader to desperately open Seiros' tomb, only to find a sword inside. Byleth disarms him and claims the sword. The sword responds to Byleth, allowing them to kill the leader. In the aftermath, Rhea is astounded that the sword, known as the Sword of the Creator, has reacted to Byleth as the last person to use it was Nemesis, who held the Crest of Flames. Despite not knowing how they inherited his crest, said to have been lost to history since he had no descendants, she entrusts it to Byleth as they are the sole person able to draw out its power.

The Verdant Rain Moon has Byleth visiting their mother's grave with Jeralt for the first time since coming to the Monastery. He shows Byleth a ring he had given to their mother and promises to give it to them one day so they in turn can give it to someone they love. Byleth's class is tasked with recovering a Heroes' Relics, a weapon said to have been forged by the Goddess herself like the Sword of the Creator. The relic was stolen from House Gautier by its eldest son Miklan, who was disowned for not having a crest. Byleth's class is able to suppress the bandits with help from Knight of Seiros member Gilbert, leaving only Miklan left. Miklan attempts to draw out the power of the Lance of Ruin, but lacking a Crest, the lance rejects him, transforming him into a Demonic Beast. It takes the entire class to take down the beast, leaving behind the lance and corpse of Miklan. The lance is safely returned to House Gautier, though Byleth and the house leader are left to ponder the true nature of the Crests and Hero's Relics.

One free day, Byleth and Sothis spend some time trying to uncover more about her origins in their Paralogue, traveling to Zanado, a place of importance to Sothis, though she does not know why. While lost in thought, they are attacked by Demonic Beasts, though they are saved by their students who had trailed them.

During the Horsebow Moon, Flayn is kidnapped, supposedly by a reaper who appears only at night. At the end of the month, Byleth discovers a hidden passage in Jeritza's room as well as a wounded and unconscious Manuela. While the house leader takes Manuela to the infirmary, the rest of the class dispatches the Death Knight's forces and is able to rescue Flayn after the mysterious Flame Emperor forces him to retreat. Byleth also discovers a Black Eagles student named Monica who had gone missing the previous year.

The Wyvern Moon gives the students a break from their monthly missions for another house mock battle competition, this time with slightly higher stakes and a prize for the winner. Despite the improvements of the other houses, they are all ultimately no match for Byleth's. During the month, after a heart-to-heart session, Jeralt tells Byleth to search his office for something important in the event that he dies on a mission.

Near the end of the Guardian Moon, several Academy students go missing when exploring a nearby abandoned chapel. Byleth, their class, and Jeralt investigates the ruins only to find several students being attacked by monsters. They are able to defeat the monsters, but it is revealed that the beasts were actually transformed students. Among the students rescued was Monica, who thanks Jeralt. However, with his back turned, Monica takes out a dagger and plunges it into his back. Byleth desperately uses Divine Pulse in order to prevent his death, but Thales appears in the rewound time and deflects Byleth's attempt to stop Monica. Unable to stop his assassination, Byleth holds Jeralt as he dies, crying for the first time. In the aftermath, Byleth kept grieving, until the house leader comforts them and implores them to keep moving forward as Jeralt would have wanted.

Honoring their father's late request, Byleth uncovers his diary, recounting his growing distrust of the Church and Rhea as well as Byleth's infancy. He also left behind Sitri's ring, which he wanted Byleth to give to their lover when the time came for them to find their own happiness.

After learning the whereabouts of Kronya, their father's killer, Byleth confronts her in the Sealed Forest, bent on revenge, and with the assistance of the class they are instructing, they are able to corner her. However, Solon appears and sacrifices Kronya to activate a ritual, sending Byleth into a dark void. As Byleth and Sothis are left helpless, Sothis remembers that she is, in reality, the progenitor god of Fódlan herself. With no other means to escape, Sothis volunteers to merge with Byleth, granting them the full extent of her powers, but at the cost of her consciousness disappearing from them. Their resulting fusion causes a surge of power to erupt around them, turning their hair and eyes light green and unlocking the true power of the Sword of the Creator. The sword is able to cleave a portal back into Fódlan and Byleth uses it to kill Solon.

Upon returning to the monastery, Rhea leads Byleth to the Holy Tomb to sit on the throne to awaken their true power. Suddenly, the Holy Tomb is besieged by the Flame Emperor and some hired bandits determined to steal the Crest Stones stored there. Byleth's class is able to stop most of the bandits and recovers as many Crest Stones as they can. Left with the Flame Emperor, during a great clash, the mask of the Emperor is knocked off, revealing that Edelgard has been the Flame Emperor the entire time.

The events of the story of Three Houses differ greatly from this point. If the Blue Lions were chosen, the Azure Moon plot starts from here. If the Golden Deer were chosen, the Verdant Winds plot starts from here.

If the Black Eagles were chosen, two separate paths occur from this point. If Byleth decided to attend Edelgard's coronation as Emperor of the Adrestian Empire, they are given the option to either continue to fight for the Church of Seiros and Rhea or defect and fight for Edelgard's cause, leading to the Silver Snow or Crimson Flower routes respectively.

Cindered Shadows[]

At some point after acquiring the Sword of the Creator, but before merging with Sothis, Byleth and the three house leaders discover a hidden passage while tailing a mysterious figure in the dead of night. Inquisitive, Byleth and the three house leaders, as well as Ashe, Linhardt, and Hilda investigate and wind up below the Academy in a hidden area known as Abyss. It is here that they encounter four ruffian students who call themselves the Ashen Wolves, the unofficial fourth house of the academy.

It is later revealed that Sitri's grave is actually empty as Rhea could not bear to bury her after her death. She instead froze her in time and placed her in the abyss.

War Phase[]

Silver Snow[]

"Just a minute! The following section contains spoilers. Viewing it will cost a lot. Are you prepared to pay for it?"

If Byleth remains true to Rhea and the Church of Seiros, they will attempt to defend Rhea during the Adrestian Empire's surprise assault on the monastery before being knocked into a ravine by a magical blast. Five years later, they lead the rebuilding of the Church Forces at Garreg Mach Monastery into a resistance army capable of standing against the Adrestian Empire and saving Rhea.

Byleth leads the resistance army to Enbarr and defeat the empire with the deaths of Hubert and Edelgard. Edelgard, in her final moments, states that for the war to end, Byleth must kill her, and Byleth personally executes her. They then learn, in a posthumous letter from Hubert, of the location where Rhea has been held in confinement for five years, as well as the existence of Those Who Slither in the Dark, who reside in Shambhala. Hubert's letter states that the land will not know peace as long as Those Who Slither remain a threat, and thus Byleth leads their army to Shambhala. Rhea, still ailing from her years of confinement, insists on seeing the enemy for herself and travels with them.

At Shambhala, Byleth defeats Thales, who in his last moments triggers a last-ditch assault of Pillars of Light. Rhea takes the form of The Immaculate One in an effort to staunch the assault and protect Byleth and the Church forces, and is gravely injured in the process. However, with the Empire and Those Who Slither in the Dark both defeated, the Church is able to begin coalescing the fragments of the former Empire, Kingdom, and Alliance into a singular nation that the Church asks Byleth to lead, as it is feared that the stresses and injuries that Rhea has endured leaves her without much time left. When Byleth has had time to ponder their decision, they approach Rhea, who asks that they first listen to what she has to say.

Rhea apologizes to Byleth personally, and explains that it was her actions that made them who they are. In her desire to see her mother Sothis again, she engaged in experiments, attempting to create a vessel for the goddess. Her twelfth attempt, a failure like those before, was a young woman with the Crest Stone of the progenitor goddess planted in her heart. The woman grew up without any signs that the goddess inhabited her, and eventually fell in love with Jeralt, who by that time had Rhea's blood transfused into him. In their union, the woman grew pregnant with Byleth, but at birth, they were stillborn, and their mother was on the verge of death, as well.

Byleth's mother pleaded for Rhea to save the baby, and Rhea did as she wished. She removed the Crest Stone from the woman's heart, and implanted into Byleth's still heart. Byleth was given life and a pulse, but lacked a heartbeat or the ability to express emotion. Despite this, Rhea kept her deeds a secret from Jeralt, who came to suspect her of ulterior motives and never realized that if Rhea hadn't acted, Byleth would have remained dead at birth.

As Rhea concludes her explanation and her apology, her weakened body gives out, and she is consumed by the power of The Immaculate One. Driven into a violent, uncontrolled frenzy, she becomes a threat to the whole land, and Byleth is forced to lead their forces into battle one more time to stop her. Once they defeat her, she is returned to herself, and she sees her mother in Byleth before she passes. If Byleth has obtained an A-Rank or higher support with Rhea, then she survives the battle. Regardless of her fate, the Church of Seiros forms the United Kingdom of Fódlan and crowns Byleth as its ruler.

Azure Moon[]

"Just a minute! The following section contains spoilers. Viewing it will cost a lot. Are you prepared to pay for it?"

A month prior, the Pegasus Moon has a grand ball held for the three houses to dance with one another. That night the Blue Lions gather to reminisce their year. They soon realize that their time in the school would only last for a little while longer, and they all promise that they would meet again together as a class in five years for the Millennium Festival. Dimitri, alone with Byleth, reveals that he and Edelgard are step-siblings, though they only spent a short time together. Before she left, he gifted her a dagger as a present. Nearby, he catches a glimpse of the Flame Emperor conversing with Thales. When he steps in to confront them, the two teleport away, but Dimitri discovers a dagger on the ground where the Flame Emperor was.

The revelation of the Flame Emperor's identity as Edelgard causes Dimitri to snap as his suspicions were confirmed that the two were one. Having believed to have caused the Tragedy of Duscur which resulted in the death of his father, his step-mother (Edelgard's birth mother), and countless others, Dimitri flies into a berserker's rage that not even Byleth can quell.

Her intentions revealed, Edelgard retreats and her first act as new Emperor of Adrestia is to declare war on the Church of Seiros. Byleth leads the Blue Lions as the first line of defense against the Empire, even facing off against Edelgard herself. Edelgard regrets not having Byleth on her side and the two clash, but Byleth emerges victorious. A sudden second wave of Adrestian soldiers charge the castle and its worn soldiers, forcing Rhea to unleash her true form as a dragon. Seeing her struggle against Demonic Beasts, Byleth goes against her orders and tries to help her. Thales appears on the battlefield and casts an orb of magic, causing Byleth to plummet over a cliff into the valley below the monastery. Eventually the Monastery loses the battle and the students, faculty, and knights are forced to evacuate, especially with Rhea and Byleth both going missing in the aftermath. Many would search for them, but none were able to find Byleth's body.

Byleth survived, being discovered in a river near a village where a villager informs them that five years had passed. Heading back to the Monastery, now in ruins, they find a solitary figure, a battle-worn Dimitri. The five years has changed the once chivalrous prince into a ruthless and cold warrior. Believing Byleth to be yet another specter of an important loved one he failed to protect, Dimitri heads into a local village near the monastery that had been pillaged by bandits, bent on dealing justice to them. Byleth follows him and the two fight off a horde of bandits. As the battle unfolds, Gilbert and the Blue Lion core members join the fray, fulfilling their promise to reunite. The Blue Lions are elated to have found not only Dimitri, but also Byleth who was missing for years. The sole member still missing is Dedue, who was supposedly executed after helping Dimitri escape the Kingdom after he was sentenced to death by the Kingdom's current leader, Cornelia.

With the Monastery back under their control, they use it as their base of operations as they seek assistance from the few Kingdom nobility resisting Cornelia's rule and plot to kill Edelgard to stop her conquest. Dimitri, consumed by his quest for vengeance, leads the army into aggressive battles against Imperial Forces. Their first battle is against an Imperial force tasked with scouting the Monastery after rumors of its reconstruction have begun to spread. The force's leader, Randolph is captured leading to a conversation between Dimitri and him over the sophism of their actions. While Dimitri planned on slowly torturing him, Byleth grants Randolph a mercy kill to spare him of further suffering.

Byleth follows along with Dimitri's initial goals to attack the Empire, but the prince's actions become more and more reckless. Due to both Gilbert's wisdom and Byleth's guidance, Dimitri's choices are mitigated enough that the others are not put entirely at risk. Felix's father, Rodrigue, later joins, providing support to Dimitri's cause and becoming another source of guidance for him. If Dedue's paralogue has been completed, it is revealed that he is alive after rescuing Dimitri thanks to the help of the Duscur men he helped save five years prior. With the full Blue Lions house reunited and the Great Bridge of Myrddin under their army's control, the event forces the Empire and Alliance to meet Byleth and Dimitri's army at Gronder Field in a situation that echoes the mock battle from five years prior. The clash of the three armies leads to many casualties, but the Blue Lions emerge victorious, forcing Claude and Edelgard to retreat, the latter severely wounded. Dimitri vows to chase after her by himself but Byleth, Gilbert, and Rodrigue stop him from going off on his self-imposed suicide mission.

Suddenly, a young girl rushes onto the battlefield and attacks Dimitri, inflicting a heavy wound. Just as she is about to deal the killing blow, Rodrigue steps in and sacrifices himself, allowing Byleth the opportunity to kill the girl. This moment becomes a turning point for Dimitri as Rodrigue absolves him of any guilt that he may have imposed on himself by the deceased. As a heavy rain falls, Dimitri is left to wonder about his purpose. Byleth extends their hand to him, offering to continue to guide him on his path as his teacher. With the weight lifted from his shoulders, Dimitri returns to his old self and becomes more objective in his goals. He decides to first reclaim the Kingdom, killing Cornelia and formally claiming his birthright. Though he is nervous to greet the masses, Byleth encourages him to face them and Dimitri finds the people of Faerghus eager to see the return of the true king.

With the Kingdom back in their hands, they receive a call for help by Claude against an impending Imperial invasion of the Alliance territory. Heeding his request, Byleth and Dimitri lead the Blue Lions in quelling the invasion. Grateful for their rescue, Claude announces that the Alliance has formally disbanded with the intention of merging with Faerghus. Dimitri accepts his offer and receives Failnaught to use in his cause as Claude departs Fódlan to take care of personal business in Almyra. With even more forces at his disposal, Dimitri begins the assault on the Adrestian Empire to stop Edelgard, though this time, he is willing to parley with Edelgard. Claiming Fort Merceus by defeating the Death Knight, Dimitri dispatches a messenger to Edelgard, asking her to parley with him in person. Edelgard heeds the request and meets him and Byleth. Edelgard declares her vision for Fódlan and refuses to ally with Dimitri. Heartbroken that the two must cross blades, Dimitri returns the dagger she dropped five years earlier and the two depart ways to prepare for their final battle.

The assault on Enbarr marks the start of the final battle as the Kingdom army overwhelms the Empire's forces, including Hubert, who is killed in the battle. Cornered in the castle, Edelgard unleashes her dual Crests, transforming into a hideous monster, granting her incredible power. The combined forces of Byleth, Dimitri, and the Blue Lions eventually take down Edelgard, causing her transformation to dispel. Left mortally wounded, Dimitri offers her hand and another opportunity to help him build a better future for Fódlan. Edelgard instead throws the dagger at Dimitri, striking his shoulder just as he stabs her with Areadbhar, killing her. The duo depart the empire having ended Edelgard's ambitions. With the war over, Rhea, weakened by her time in imprisonment, steps down as Archbishop while Byleth assumes the title, leading the Church of Seiros. Dimitri formally becomes king of Faerghus, now comprised of the entirety of Fódlan. The former teacher and student help to lead Fódlan into a better future.

With her intentions revealed, Edelgard becomes the new Emperor of Adrestia and her first act is to declare war on the Church of Seiros. Byleth leads the Golden Deer house as the first line of defense against the Empire, even facing off against Edelgard herself. Edelgard regrets not having Byleth on her side and the two clash, but Byleth emerges victorious. A sudden second wave of Adrestian soldiers charge the castle and its worn soldiers, forcing Rhea to unleash her true form as a dragon. Seeing her struggle against Demonic Beasts, Byleth goes against her orders and tries to help her. Thales appears on the battlefield and casts an orb of magic, causing Byleth to plummet over a cliff into the valley below the monastery. Eventually the Monastery loses the battle and the students, faculty, and knights are forced to evacuate, especially with Rhea and Byleth both going missing in the aftermath. Many would search for them, but none were able to find Byleth's body.

Byleth survived, being discovered in a river near a village where a villager informs them that five years had passed. Heading back to the Monastery, now in ruins, they find Claude, now leader of the Leicester Alliance, waiting for them. Claude informs Byleth of what has happened to Garreg Mach during the five years they were gone and the two share a meal together. Waiting for the other students to turn up to the five-year reunion, the two explore the ruins of the monastery and come across a group of bandits pillaging a local village, leading to a fight. As the battle unfolds, the Golden Deer core members join the fray, fulfilling their promise to reunite, and are elated to see that their old professor is alive.

With the Monastery back under their control and the return of the Knights of Seiros, the two parties form an alliance and use it as their base of operations as Claude suggests leading an army capable of standing against the Adrestian Empire and saving Rhea. Despite Byleth's hesitance to join the Alliance's cause, Claude convinces them to stay to protect their students and find out more about themselves by finding Rhea with their old class. Fighting under the banner of the Crest of Flames, Byleth and Claude's army successfully repels an Imperial incursions into Garreg Mach, meets with Judith at Ailell to bolster their numbers, and capture the Great Bridge of Myrddin to settle internal divisions within the Alliance and unify the nation's full might.

Upon entering the Empire and arriving at Gronder Field, the Alliance army meets the Imperial army led by Edelgard and a Kingdom army led by Dimitri, presumed dead after the coup in Fhirdiad, and emerges victorious after a gruesome three-way battle, with Edelgard wounded and forced to retreat to Enbarr and Dimitri meeting his end in pursuit of her. The Alliance army then pushes their momentum and captures Fort Merceus, the greatest obstacle on the way to the Imperial capital, but javelins of light fall and destroy the fortress, forcing the Alliance to regroup elsewhere.

Byleth leads the Alliance army to Enbarr and defeat the Empire with the deaths of Hubert and Edelgard. In her final moments, Edelgard states that for the war to end, Byleth must kill her, and Byleth personally executes her. They and Claude then learn, in a posthumous letter from Hubert, of the location where Rhea has been held in confinement for five years, as well as the existence of Those Who Slither in the Dark, who reside in Shambhala. Hubert's letter states that the land will not know peace as long as Those Who Slither remain a threat, and thus Byleth leads their army to Shambhala. Rhea, still ailing from her years of confinement, insists on seeing the enemy for herself and travels with them.

At Shambhala, Byleth defeats Thales, who in his last moments triggers a last-ditch assault of Pillars of Light. Rhea takes the form of The Immaculate One in an effort to staunch the assault and protect Byleth and the Alliance forces, and is gravely injured in the process. However, with the Empire and Those Who Slither in the Dark both defeated, the Leicester Alliance forms into a singular nation. With the stresses and injuries that Rhea has endured leaves her without much time left, Byleth and Claude approach her when the situation has calmed down, determined to find out the truth about everything.

Rhea apologizes to Byleth personally, and tells them and Claude the truth about herself, the goddess, Agarthans, Nemesis, the Ten Elites, and the origins of Crests and the Heroes' Relics.

As Rhea concludes her explanation and her apology, a soldier arrives and informs them of an unidentified military force is attacking from the east and approaching Garreg Mach, with the leader wielding a weapon resembling the Sword of the Creator and flying a banner bearing the Crest of Flames. Rhea quickly puts together that the leader is Nemesis himself and tells Byleth to put an end to Fódlan's blood-stained history. After a fierce battle against the resurrected Nemesis and the Ten Elites, Byleth deals the final blow and slays Nemesis, causing the ancient army to disappear like ash. Whether Rhea passed away or is simply too injured to rule is left ambiguous and the Church of Seiros forms the United Kingdom of Fódlan, crowning Byleth as its ruler.

Byleth grows close to the Black Eagles house, particularly to house leader Edelgard. Should they forge a strong enough bond with her, she asks them to accompany her on a week trip to the Empire where she formally ascends the Adrestian Empire's throne as its new Emperor.

After being unmasked in the Holy Tomb, Edelgard is shocked, but elated when Byleth chooses to ally with her. Incurring Rhea's fury, they retreat to the empire, where they launch an attack on the monastery. Though they defeat the Church's soldiers, Rhea transforms into The Immaculate One and launches a fireball at Byleth, sending them plummeting into a ravine; their students are unable to find them, but still hope they are still alive.

Five years later, Byleth is woken by a villager who found them drifting along a river, and they immediately head back to the monastery despite his warnings that the monastery is occupied by Imperial forces. They make their way to the Goddess Tower and find Edelgard, who is shocked and elated to see they are alive and well. Edelgard brings them up to date with all the events they have missed since then, before bringing them to the rest of Black Eagle Strike Force, all of whom are happy to see their professor safe and sound. Byleth's presence allows Edelgard to end the three-way stalemate between the warring factions, and they make numerous gains over their enemies.

In the final battle, Rhea transforms into her dragon form in hopes of killing Byleth and reclaiming the Crest of Flames that they bear. A brutal battle ensues, but Byleth and Edelgard are able to kill Rhea. Suddenly, Byleth collapses and when Edelgard checks their heart, she hears no pulse. As she weeps for her teacher, the crest stone dissolves from their heart and for the first time, their heart begins to beat as Sothis' power vanishes. With the Church of Seiros formally dissolved and control of Fódlan in Adrestian hands, the continent begins to see huge reforms under Edelgard's rule. Though they have lost the power of Sothis, Byleth spends the rest of their life to end Those Who Slither in the Dark and becomes a lifelong confidant to Edelgard.

Warriors: Three Hopes[]

During a mission, Shez's comrades are wiped out by Byleth, and Shez themselves are nearly killed battling them. As Byleth prepares to execute them, Shez suddenly hears a mysterious voice and is granted overwhelming power. However, this new power is still not enough to defeat Byleth, who leaves them alive after Jeralt completes their mission and orders a retreat.

Byleth continues working alongside Jeralt's Mercenaries, and as the war breaks out, the mercenaries work with a faction that opposes Shez's alignment, and battle Shez and their army on several occasions.

Anna fates portrait
"Just a minute! The following section contains spoilers. Viewing it will cost a lot. Are you prepared to pay for it?"

During one such encounter, Shez's fight with Byleth results in the latter unleashing Sothis' power, causing Byleth's hair and eyes to turn light green for the remainder of the story.

In another encounter in Part II of the story, Shez's faction sees an opportunity to break the mercenaries' contract, effectively allowing them to recruit Jeralt's mercenaries. If they rout Byleth, Byleth will learn of Jeralt's death from Alois, and are persuaded by Sothis to take up revenge with her help, and choose to pursue Shez, leaving Alois in charge of what remains of Jeralt's mercenaries. Eventually, Byleth confronts Shez once again, only to be slain after Shez phases through their attack and lands a fatal blow on them, which in turn also kills Sothis.

If Byleth is not defeated in the fateful encounter, the mercenaries are successfully recruited, with Byleth, alongside Jeralt's Mercenaries, joining Shez's faction for the remainder of the story. However, later in the story, Arval takes control of Shez and starts attacking Byleth when the two are alone, but Byleth is rescued by their allies. Despite this, Byleth realizes that Shez was not fully in control during the attack, and holds nothing against them.

After the war breaks out, in Chapter 5, Jeralt's Mercenaries are initially taken up by the Kingdom army, with Ingrid seen giving orders to Jeralt before the battle in Magdred Way takes place. While Shez and the Imperial army come to aid Lonato in the battle, Jeralt's Mercenaries ambush them, with Byleth among the mercenaries. The mercenaries are beaten back, however, and Byleth is forced to retreat.

Byleth and the mercenaries are next seen working for the Leicester Alliance in Chapter 7, where they reinforce the Alliance army in an attempt to stop Count Bergliez and his men from escaping. Despite their presence, the Imperial army successfully extracts Count Bergliez and Byleth is defeated. It is then that Byleth unleashes Sothis' powers when doing battle with Shez, forcing the latter to retreat.

During Chapter 10, Jeralt's Mercenaries are hired by Rodrigue to fight the Imperial army, with Jeralt leaving command of the main force for Byleth as he leaves to handle a backup squad. Should Shez opt to avoid Byleth and go straight for Rodrigue, the mission will end once Rodrigue is slain. Having failed their mission, Byleth surrenders with the rest of their forces. They later decide to accept working for the Empire alongside Jeralt and Alois, having no hard grudges against Shez.

If Byleth was routed in that battle, they then come across Randolph, whom they slay in front of his sister Fleche. Before Byleth can kill Fleche, however, they are distracted by Shez, with Hubert, Edelgard and much of the Imperial army behind them, and is forced to flee the scene.

Byleth is next seen with Claude in Chapter 14, apparently tipping him off about the Empire. Although the details are not known, this results in Claude choosing to break the pact he had made with the Empire, and declare war on the Empire, starting with the upcoming battle in Ailell, which becomes a three-way standoff. Byleth, now controlled by Sothis, joins the fray after the Empire has defeated both the Kingdom and Alliance, but is defeated and slain once and for all.

As the war breaks out, Byleth, alongside Jeralt's Mercenaries, first appear in Chapter 5, where they reinforce the Imperial army. However, they are stalled by Miklan, and are forced to retreat, either by being routed themselves, or because Jeralt ordered their retreat after being defeated himself.

Byleth is next seen in the next chapter, where they defend Arundel territory alongside Bernadetta and the Death Knight. Despite their overwhelming strength, the Kingdom army's tactics and numbers prove supreme, and Byleth is beaten back. There, they awaken Sothis' power while battling Shez, causing the latter to retreat.

They next appear in Chapter 12, where they are assigned by Randolph to assist in the defense of Hevring territory alongside the rest of Jeralt's Mercenaries. If Shez and their army manage to avoid Jeralt's mercenaries and defeat Randolph without defeating Byleth, the mercenaries surrender themselves to the Kingdom, and Byleth among them joins the Kingdom army for the remainder of the war.

On the other hand, if Byleth was defeated, they chance upon Rodrigue and stab him in the back while he converses with Dimitri and Felix, who were inspecting the aftermath of the battle. Felix tries to lunge at them, but they use Sothis' powers to warp past him and behind Dimitri. Before they could react, Byleth resists her and flees.

In Chapter 14, shortly after the Kingdom army slay Duke Aegir in their search for Edelgard, Byleth, under Sothis' control, then reappears in front of Shez, intent on defeating them once and for all. However, it is Byleth who is defeated; with Sothis slain, their body is left motionless where it fell.

After the war breaks out, Byleth, alongside Jeralt's Mercenaries, is first seen in Chapter 6, where they were hired by Hubert in an attempt to help cover the Imperial army's retreat from Alliance territory. This ploy proves partially successful, with Ferdinand and his unit managing to escape. However, the mercenaries are defeated, the rest of the Imperial forces are routed (with Ladislava slain and Bernadetta either killed or defected), and Byleth is forced to retreat.

When the Alliance begins a counterattack on Bergliez territory in the next chapter, Byleth appears alongside Jeralt's Mercenaries once again. Although they are temporarily contained by the Alliance army, they eventually manage to break free just as Claude orders the Alliance to retreat, and engage Shez once again. Newly unleashing Sothis' power, Sothis manages to nearly overwhelm Shez, but Byleth breaks free of her control, allowing Shez to escape.

Byleth and Jeralt's Mercenaries are next seen in Chapter 10, having been hired by Fleche to ambush the now re-named Federation army to avenge Randolph's death in the previous battle at Ailell. If Byleth was avoided in the ensuing battle and Fleche is defeated, they, alongside Jeralt's Mercenaries, surrender to the Federation army and joins their side for the rest of the war.

If Byleth was defeated in that battle, however, they are later seen fighting the Federation forces on their own. Judith charges at Byleth to protect the soldiers, but is struck down as she duels with them. Shez arrives as a witness to the scene, and allows Byleth to flee, choosing to tend to Judith in her final moments.

Their next appearance comes at Chapter 14, where they appear after both Kingdom and Church forces have been driven off from Garreg Mach. Now under Sothis' control, they engage in one final duel with Shez, but is defeated and killed.

Engage[]

Byleth appears in Engage solely in his male form as an Emblem. Emblem Byleth's spirit is housed in the Ring of the Instructor. When the Emblem Rings were distributed across Elyos, the Ring of the Instructor was one of the six rings retained in Lythos. Shortly after the awakening of Alear from their thousand year slumber, Lythos was attacked by Elusia who raided the Ring vault, stealing the four Rings there, including the Ring of the Instructor. Princess Hortensia would use Byleth's ring during her fights against Alear and their forces until she eventually joined them. Upon recovering the ring, Alear purified it of Sombron's corruption, allowing them and their forces to utilize his power.

Personality[]

Byleth has a very subdued personality and has difficulty expressing emotion. As a newborn, they neither laughed nor cried. People they are especially close to, such as Jeralt, are able to tell how they are feeling despite their limited emotional visualizations. A handful of their students note that their outward expressions hardly vary. Some express surprise whenever they simply smile. According to Alois, this trait of theirs may in part come from their father, as Jeralt does not show his emotions easily either and can also be difficult to read. However, in the support conversations between Byleth and Jeralt in Three Hopes, Jeralt notes how similar Byleth is to their mother Sitri, who like Byleth had difficulty expressing emotion.

Their stoic demeanor slowly changes over the course of the Academy phase. Jeralt notices that they have become more expressive over the first few months, likely a result of the bonds they have formed with their students. Despite appearing indifferent, Byleth can be perceptive of their students and fellow faculty's problems and serve as a great source of emotional support for their issues. As the story unfolds, their emotional expression becomes more dynamic, including sorrow, vengefulness, and happiness. Because Jeralt sheltered Byleth from knowledge about a number of aspects of the world, Byleth becomes curious about the influence of the Church of Seiros, the mystery of the Crests, and the dynamic of the three nations once they are brought to Garreg Mach Monastery and the Officers Academy.

Byleth has somewhat of a reputation from their earlier years in their father's mercenary corps for being a fearless and skilled warrior, gaining the moniker of 'Ashen Demon' due to the seemingly emotionless ways they dispatched their enemies. This seems to be somewhat of a sensitive subject for them, as they seem uncomfortable when Hanneman mentions their moniker in their C support. It is notable that in the beginning of the game, Sothis refuses to let the player progress if they do not acknowledge their humanity to her, refuting the "Ghost" and "Demon" options, so it can be inferred that Byleth is uncomfortable with the Ashen Demon moniker because it dehumanizes them.

The three house leaders of the Officers Academy attest to their martial prowess and have deep, profound respect for their abilities and guidance in battle and in the classroom. They alongside the other students continue to refer to them as teacher or professor even after the time-skip. The three house leaders also deeply regret that Byleth had not chosen their house if they are not teaching theirs, seeing the value in their strengths.

According to both genders of Byleth in Heroes, they do not actually know the distinction between a friend and an ally due to their unusual childhood. Nevertheless, they are well liked by the student body, even those not in in their initial house. Their wisdom ultimately shapes the outcome of the events of Three Houses providing council and guidance to the house leader they chose to teach, helping to shape them into better warriors and leaders. Several students can develop an interest in them and eventually switch over to their house if not already in them. This results in them also joining their faction during the War, even those from enemy nations defecting to their cause, thus changing their fate. Those who do not join will often express regret facing them in battle. However, some students and faculty members, especially in Crimson Flower, will instead express outrage at them, vowing to kill them by their own hands.

According to their profile in Cindered Shadows and Three Hopes, Byleth has interests in helping and listening to people, likes their father, swords, reliable allies, smiles, and being trusted, and has no apparent dislikes. However, they point out in their expedition dialogue that they detest senseless killing, and if someone were to harm their father, they could never forgive them, which is indeed true for both games.

Route Specific[]

Byleth's personality is subtly influenced by the students in their chosen house.

Anna fates portrait
"Just a minute! The following section contains spoilers. Viewing it will cost a lot. Are you prepared to pay for it?"

In Verdant Wind, Claude's inquisitiveness and charm makes Byleth more comfortable with seeking information and sharing secrets. At several points in the Academy Phase, He encourages them to express themselves and question the world around them. In the aftermath of Where the Goddess Dwells, Byleth shares the entire truth with Claude about Sothis living inside of them, in contrast to the other routes where they make a vague statement about receiving the goddess' power. Byleth's newfound curiosity is also shown when they further study Jeralt's diary, wanting to learn more about their late father. During the War Phase, Claude manages the war effort and introduces Byleth to the politics of the Leicester Alliance, likely in an effort to prepare them to eventually take the role of Fódlan's ruler. Byleth's ending with Claude shows that, while hesitant to accept this role at first, Claude knows that they are ready.

In Azure Moon, Dimitri repeatedly encourages Byleth to show more emotion during the Academy phase. On one occasion, he scolds them for not having an appropriate emotional reaction, which ironically seems to cause genuine sadness in them. Byleth's progress during the Academy Phase shows clearly during the War Phase, where seeing how deranged Dimitri has become causes Byleth great sadness as they attempt on multiple occasions to bring back his old personality. Following Rodrigue's death during Blood of the Eagle and Lion, Byleth shows genuine compassion and empathy, which is enough to pull Dimitri from his grief.

In contrast to the other two lords, Edelgard does not seem to mind Byleth's seeming lack of emotion, and even notes that they share a similar personality. Due to her generally harsh and cold outlook, Edelgard does not offer words of comfort to Byleth after their father's death, but instead encourages them to toughen up and continue moving forward. The bond between Byleth and Edelgard can potentially prove strong enough that they turn against the church, acting as her loyal general and confidant during the war. During the War Phase, Byleth shows a more playful side, as they seem to enjoy teasing Edelgard on multiple occasions.

During the War Phase of Silver Snow, Byleth is single-mindedly devoted to finding Rhea, both out of loyalty and due to believing she has the truth of their origins. Their bond with Edelgard is still strong enough for them to feel hesitant about fighting her while invading Enbarr, wishing that there was another way. After Those Who Slither in the Dark are dealt with and Rhea is grievously injured, Byleth is similarly hesitant about the prospect of taking up the position of Fódlan as a whole, but ultimately accepts the role.

Overall[]

Secret Book (Artwork)
Subjective: The following part of this article is based upon the editor's personal experiences and opinions, and therefore may not be applicable for all readers.

Byleth's main claim to fame is their sky-high base Strength of 13, higher than any student in the game besides Edelgard, making them a major asset early on and keeping their Strength comparable to the best throughout. They have no particularly abysmal growths save for the low 30% in Resistance and slightly higher 35% in Magic and Defense. With every other stat having a 45% growth, Byleth is a flexible unit and potent fighter regardless of whatever class they are put in, though they have an emphasis on physical classes due to their very high base and better Strength growth. Their personal skill, Teacher's Guidance, initially gives them and any adjacent ally a 20% EXP boost during combat, giving them perfect utility in strengthening their allies. During Chapter 10, Byleth also gains a +2 damage boost to their attacks. Byleth's role as the main character does mean that while they are potent, they still need some level of caution used as when they fall, it instantly causes Divine Pulse to activate, thus using one of the charges (this does not happen if playing Casual Mode unless the mission specifies that Byleth must survive).

Byleth is one of the best Battalion users as their Charm growth is the easiest to improve. By using Tea Times and choosing the correct topics, they can gain 1 Charm point at the end. Byleth also can easily make usage of Faculty Tutoring to improve specific subjects. With proper planning, this makes recruiting students from other houses much easier without having to use any of the subjects during battles.

Byleth's spell pool is fairly average with a mixture of damage from their Reason list consisting mainly of Fire based spells and a both offensive and utility Faith spells, which gives them the option of using magic based classes. This, combined with their fairly low base 6 Magic, means they're not very capable as a magical unit. Though their Reason list is ultimately uninteresting (though still reliable), their access to Aura is unusual as only Dimitri, Marianne and Yuri have access to it otherwise. It has very high Crit for a spell, tying with Death Γ and topped by Fimbulvetr, and this combined with Byleth's budding talent in Faith means it is better to prioritize Faith if one intends to use magic as a secondary ability as the Enlightened One.

Byleth's subject strengths are in Sword, Brawl, and Authority, which all sync naturally with their exclusive story promotion Enlightened One. They also have a Budding Talent in Faith, granting White Magic Avoid +20 giving them extra avoid when equipped with a Faith spell. With no Subject Weakness, Byleth can apply themselves into any class possible, depending on player preference and in some cases, their gender.

Initially, Byleth should master Commoner for more early game survival via HP+5. Physically oriented Byleths should then master Soldier and then Brigand, as the former has the best positioning combat art that will likely stay useful through out the playthrough, and the latter grants the ubiquitous Death Blow.

Magically oriented Byleths should go through Monk and master Mage for Fiendish Blow subsequently.

Physical Byleths can then choose to master Mercenary and Warrior for Vantage and Wrath respectively, which when combined with the male only class War Master's passives and master ability, Quick Riposte, will make him a force to be reckoned with on both player and enemy turns. War Master is also the arguably best physical master tier class in the game so it is definitely worth considering as Male Byleth's final class. Another option on Maddening difficulty is Grappler for its unique combat art which hits 3 times, which makes it possible to circumvent the sky-high speed stats enemies have on that difficulty.

Female Byleths will have access to the Vantage Wrath combo above, but lack access to War Master and thus need to contend with other classes unless New Game+ is utilized and Male Byleth acquires Quick Riposte in a previous game. If a penchant for flying is desired by the player, she can fit easily into Pegasus Knight and Wyvern Rider, and eventually either Wyvern Lord or Falcon Knight. Alternatively, she can combine Aegis and Pavise as well as Darting Blow and Desperation to make for a speedy tank type character, where Darting Blow and potentially Weight -3 or 5 offset the malus the armor and cavalry classes impose on her Speed growth.

Female Byleth will also make for the more effective mage of the two, as she can eventually promote into Gremory, doubling the spell use of any kind. Attaining the S and S+ ranks in both schools of magic will afford her both Tomefaires, as well as range extending skills, so the use of a Knowledge Gem is advised. Darting Blow and Weight -3 or 5 can also be used here effectively in order to offset the weight penalties of her spells.

Supports[]

See also: Byleth/Male Supports, Byleth/Female Supports

Byleth is able to form supports with most of the playable characters in game, including the non-playable characters Rhea and Sothis, who are only able to support with Byleth. Unlike previous games, Anna is completely unsupportable and is the only character Byleth cannot form a support with.

Byleth can also form an S-Support in-game, though this can only be initiated during a certain chapter:

Both genders of Byleth are able to S-Support with all characters of the opposite gender, with the exception of Anna. Male Byleth can also form a same-sex S-Support with Linhardt, Gilbert, Alois, Jeritza, and Yuri. Female Byleth can also form a same-sex S-Support with Edelgard, Dorothea, Mercedes, Rhea, and Sothis.

Base Set[]

Those who owned Three Houses within the first year of its release quickly obtained a useful sword unit as a free gift. While he may face stiff competition among an already extensive existing pool of sword units, Male Byleth is a worthy contender off the gate. His stats are mainly well balanced with particularly strong offensive stats and workable physical bulk. While he may lack Res, it hardly affects his overall performance.

What sets Male Byleth apart from the rest is mainly his weapon, the Creator Sword. It packs three powerful effects starting with a special cooldown acceleration which is a fairly standard skill on many weapons already, but it works to his advantage nonetheless. Next is essentially Null Follow-Up, preventing the opponents from using skills that grant follow-ups like Quick Riposte or those that stop Byleth's follow up like Wary Fighter, stopping many hyper offense characters and most stalwart walls. Last is the negation of enemy special cooldown acceleration skills or skills that slows down Male Byleth's. The weapon alone grants huge benefits to Byleth and makes him a terrifying offensive unit.

Male Byleth's other unique skill is Ruptured Sky, boosting his Atk by 20% of his foe's Attack. This allows him to turn the enemy's high Atk against them to power up his own assaults. This bonus is further boosted to a 40% boost if he is battling a Dragon such as Tiki or either Grima. Male Byleth's damage output can be inconsistent against some enemies as a result of borrowing their Atk, but against most Arena and Aether Raid enemies, he can unleash terrifying damage on top of his already solid offense.

Male Byleth packs Distant Counter, preventing most mages from engaging him safely without taking some powerful, sometimes fatal, damage in return. Chill Speed weakens the enemy with the highest Spd on the enemy team, thus can let him double them when applied properly. Odd Speed Wave gives him a +6 Spd boost, granting him a 44 neutral Spd on even turns, much faster than most of the unmerged meta.

Counters[]

Male Byleth has very few counters as mostly bulky Blues can wall him like Fallen Hardin or Brave Hector, though he does negate any of their follow-up skills. With their high Atk, they still can take notable damage despite their bulk if he manages to activate Ruptured Sky, but they are among the most solid options to counter him. Mages with enough buffs can simply nuke him in a single cast before he can retaliate. In particular, Ophelia can do this with her AOE special charged as can Lilina if she also runs an AOE special. Staff users with Dazzling/Wrathful Staff can also safely engage him without worry of retaliation, applying the usual chip damage expected of them. He also lacks HP and Res to overcome most Panic and Ploy users as well, making him vulnerable to debuffs.

Skill Inheritance[]

Male Byleth is already good to go from the start, but the standard Reposition is highly recommended to give him a positioning ability should he not be in range to initiate an attack and instead set up a bait.

While he is vulnerable to staff users as mentioned above, he can inherit Null C-Disrupt to stop such enemies from getting free hits on him and shores up one of the main weakness in his base kit. Otherwise, improving his offense is a good option such as Wrath.

Base Set[]

Legendary Male Byleth is an impressively strong Water Season Green Tome Infantry Legendary Unit with the ability to pair up with other units. At face value, he is strongly oriented towards offense with a solid 39 Atk and 41 Spd. His overall bulk is rather low, barely scoring over 60 for both, meaning that he is essentially a glass cannon stat-wise. Nonetheless, Legendary Male Byleth's kit leaves a lot of room to annihilate his foes, especially a certain unit terrorizing the Heroes meta prior to his release.
Professorial Text is a mix of bonuses for Byleth himself and for his allies. On top of the accelerated Special Trigger effect, he gains +5 to his four core stats during combat if he is within two spaces of an ally when he initiates combat. If he has more Spd than his foe, he also neutralizes any skill that affect follow-up attacks, thus he can power through units who try to use Wary Fighter or similar effects. Finally, his allies who are within two spaces of him gain that ability as well under the same Spd condition. At the end of it all, the effects of this tome provides a powerful means to secure his damage output and allows his allies to do the same.
Sublime Heaven is his unique special skill. Against most foes, he will gain 25% bonus Atk. However, if it activates against either a Dragon or Beast, the Atk bonus becomes 50%. Also, it ignores any sort of damage reducing skill. This, on top of his tome, helps to break heavy walling units with utter ease and even the mighty Fallen Edelgard falls to him consistently.
Attack Defense Ideal grants him +7 Atk/Def if he either is at 100% HP at the start of battle or has a【Bonus】active on him. If he has both conditions fulfilled, he gains an additional +2 Atk/Def for a net gain of +9 Atk/Def. Lull Attack Resistance neutralizes any bonuses to his foe's Atk/Res and also inflicts a further -2 Atk/Res debuff. Time's Pulse accelerates his special charging if he already has his skill charged on Turn 1. With Sublime Heaven's 1 turn cooldown thanks to Professorial Text's slaying weapon effect, he will almost always have his special ready to activate.

Counters[]

With his paper thin defenses, Legendary Male Byleth's glass cannon nature leaves him particularly vulnerable during his enemy's turn. As such, attacking him when it is not his team's turn as Reds, most Greens, and some Blues could kill him in a single round.

Skill Inheritance[]

Legendary Male Byleth's only empty skill is his assist skill, which Draw Back or Reposition are solid choices for the movement utility. While his base kit on its own is fantastic in its own right, replacing his Skill A and Seal with a combination of Swift Sparrow 3 and Life and Death 3 ensures that Byleth has an explosive amount of damage on his turn as the defensive stat drop of Life and Death is ultimately rendered moot when he can simply out-damage them. With Windsweep added to the mix, he can easily and freely demolish enemies with a massive potential 53 neutral Spd or even 57 Asset Spd with the above skill combination.

Base Set[]

Female Byleth is near identical to her male counterpart as they both hold solid offensive stats and physical bulk, but are low in Res. The differences between the two are minimal at best, but she does have slightly better Spd and Res while he has slightly better Atk and Def. On a technical level, the performance differences mainly come down to Female Byleth stopping follow-ups from some of the fastest units in the game and naturally doubling over more while Male Byleth hits slightly harder and can take a few more physical hits. While some may choose to ignore her since Male Byleth already exists in their roster without having to summon him, she is simply too powerful of an asset to not try to acquire and train.

She has the Creator Sword like her male counterpart. It packs three powerful effects starting with a special cooldown acceleration, which is a fairly standard skill on many weapons already, but it works to her advantage nonetheless. Next is essentially Null Follow-Up, preventing the opponent skills that grant follow-ups like Quick Riposte or those that stop Female Byleth's follow up like Wary Fighter, stopping many hyper offense characters and most stalwart walls. Last is the negation of enemy special cooldown acceleration skills or skills that slows down Female Byleth's. The weapon alone grants huge benefits to Female Byleth and makes her a terrifying offensive unit.

Female Byleth's other unique skill is Ruptured Sky, boosting her Atk by 20% of her foes' Atk. This allows her to turn the enemy's high Atk against them to power up her own assaults. This bonus is further boosted to 40% if she is battling a Dragon such as Tiki or either Grima. Female Byleth's damage output can be inconsistent against some enemies as a result of borrowing their Atk, but against most Arena and Aether Raid enemies, she can unleash terrifying damage on top of her already solid offense.

Female Byleth's base heavily deviates from her male counterpart as she packs Fury 4, boosting her already impressive stats with a flat +4 stat boost at the cost of 8 recoil damage after every fight. This plays greatly into her Wrath, further accelerating her special and adding a vicious +10 damage when it activates. Even Attack Wave boosts her Atk by 6 on even turns, bringing her neutral Atk to 56 for outstanding damage output.

Counters[]

Female Byleth has very few counters as mostly bulky Blues can wall her like Fallen Hardin or Brave Hector, though she does negate any of their follow-up skills. With their high Atk, they still can take notable damage despite their bulk if she manages to activate Ruptured Sky with her Wrath activated, but they are among the most solid options to counter her. Mages with enough buffs can simply nuke her in a single cast, especially if she does not have Distant Counter Inherited. In particular, Ophelia can do this with her AOE special charged as can Lilina if she also runs an AOE special. Staff users with Dazzling/Wrathful Staff can also safely engage her without worry of retaliation, applying the usual chip damage expected of them. She also lacks the HP and Res to overcome most Panic and Ploy users as well, making her vulnerable to debuffs.

Skill Inheritance[]

Female Byleth is already good to go from the start, but the standard Reposition is highly recommended to give her a positioning ability should she not be in range to initiate an attack.

She more or less can emulate her male counterpart by inheriting Distant Counter to allow her to counterattack mages and Null C-Disrupt to stop staff users from chipping at her even with Distant Counter equipped.

Base Set[]

Joined by the Archbishop Rhea, Summer Byleth flies into battle as a Red Tome Duo Flier. Even without her duo skill, she is an incredibly powerful offensive unit thanks to 36 neutral Atk and 42 neutral Spd, ensuring that she hits hard and can double attack most foes. With a focus on her offense, her mixed bulk is rather low as she has 16 Def and 21 Res, meaning that she needs to defeat her opponent quickly before they have the chance to exploit her defenses. Luckily this optimized offensive stat spread is perfectly tailored together by her weapon.
Sun's Percussors not only accelerates her special cooldown, if her Spd is greater than her opponent's at the start of combat or if she is attacking a unit at 100% HP, she gains +5 Atk/Spd and also a Null Follow-Up effect, preventing her opponent from using skills like Quick Riposte or preventing her from performing a double from skills like Wary Fighter. As a result, very little can be done to stop her offense aside from outright winning over her with Spd, which only a very small handful of units can do.
Her Duo skill grants a Desperation effect, allowing units including herself to perform their follow-up attack before their opponent can counterattack. This works well on fast units and most importantly, unlike most Desperation users, this effect does not require the unit with the buff to be under a certain HP threshold to activate. Also, after three turns, she can use the effect once more, giving the player time to pace out the effect to make use of it as much as possible.
Ruptured Sky is a 1 Turn cooldown special under her unique weapon and not only boosts her damage by 20% of her foe's Atk, but if it's against a Dragon or Beast, it become as 40% boost. Attack Speed Push grants an +7 Atk/Spd boost during combat if she is at least over 25% HP, though she does suffer recoil after a fight in which she uses the boost. Chill Speed Resistance reduces the Spd/Res of the foe with the highest sum of the two stats by 5 for each. While this may lead to inconsistent activations, it can come in handy in a pinch to ensure that she kills her foe with the debuffs active. Ground Orders allows any infantry, armored, or cavalry unit to move to any adjacent tile of an ally within two spaces of themselves, giving these grounded units deceptive mobility if they are positioned correctly to their allies.

Counters[]

Summer Byleth is an absolute terror during her turn, but a lot of her power is lost during the enemy phase. Her bad defenses leave her vulnerable to a host of units on both sides of the damage spectrum, but more so physical units who hit her lower Def and Dragons who target it as well. Even without taking into account her inherent effective damage, bow users can easily fell her in a single volley.

Skill Inheritance[]

Maximizing her player turn offense is the ideal route to ensure that Summer Byleth can dominate from the skies. Reposition is a standard ally positioning skill that can help move an ally out of danger, though there are very few instances where it is safe for her to take an enemy turn attack. Life and Death gives her a flat +5 Atk/Spd boost in exchange for a -5 Def/Res drop, which barely affects the outcomes of most of the fights she would find herself in. If she can get the fourth tier of Life and Death, it is the same results as her default Atk/Spd Push without the recoil and again, only at the cost of a drop of 5 Def/Res. Her high Spd also makes for a great Windsweep as she has the Spd to use it to avoid battles against physical weapons, thus avoiding worrying about pesky Distant Counter users and bow users as well. Glimmer is a better fit for her, especially if she is going to be used on a team, such as a flier team, who can help boost her stats, therefore empowering the special's damage output.

Base Set[]

Legendary Female Byleth is a strong Wind blessed Blue Tome Infantry unit who has the ability to pair up with other units. She is extremely potent offensively thanks to her 39 Atk and 43 Spd at the cost of a rather middling bulk of 63 physical and 66 magical. She share many of the traits of her Legendary male counterpart as a offensive glass cannot, but with a few twists that makes her unique in her own special way.
Professorial Guide grants her special cooldown acceleration for faster damage output. If she initiates combat or is within two spaces of an ally, she gains +5 to her four core stats and also gains a skill that prevents a Null version of Guard, ensuring that her specials cannot be slowed nor can her foe accelerate their specials. Not only does this make her incredibly strong against stalling tanks, but this Null Guard effect also is granted to allies within two spaces of her, making her a powerful support unit as well.
Goddess Bearer is her Legendary Skill C and, at the start of her turn, if she is within two spaces of an ally, she gains a visible +7 Atk/Spd,【Null Follow-Up】, meaning if her Spd is higher than her foe's, she neutralizes any skill that gives her foe a follow-up or prevents her from performing a follow-up, and also a self-Ground Orders so she can warp to any space adjacent to an ally in two spaces of her. Together with her tome, Legendary Female Byleth has incredible offensive output that can punish stall units to an extent and can, like her male counterpart, hard counter one of the most menacing units in the Heroes meta.
She has Ruptured Sky which boosts her damage by 20% of her foe's Atk, increasing it to 40% if he foe is Dragon or Beast, making her even more dangerous against the likes of Fallen Edelgard, Fallen Rhea, and Ash. Attack Speed Ideal in its fourth tier grants her another visible +7 Atk/Spd if she either starts turn with a【Bonus】or is at full health. Given her Goddess Bearer skill, unless she is completely isolated out of its range, she will have this boost. Lull Speed Resistance inflicts Spd/Res-3 on her foe and neutralizes their existing bonuses during combat, boosting her overall damage output by increasing the speed difference to gain more follow-up attacks and reducing their magical defense.

Counters[]

Legendary Female Byleth is very frail and thus weakest on her opponent's turn if they get the first attack. Melee range units, especially Greens, reliably deal with her and prevent her from counterattacking as a defensive phase build is not optimal for her. Guinivere hard counters her, even with the standard sweep build, as she has the raw magical bulk and the effective damage against mages secure a kill onto Legendary Female Byleth.

Skill Inheritance[]

With only her Assist skill missing, Reposition or Draw Back are excellent options. To safely engage on more foes, Legendary Female Byleth benefits greatly from Watersweep or Windsweep, both of which has their restrictions, but the matter of choice makes both viable depending on the situation.

Base Set[]

Placing second for the women's division and fourth overall of the Choose Your Legends 6 event, Brave Female Byleth is a potent Colorless Tome Flying form built for speed with her innate 43 Spd as well as a solid 41 Atk to hit hard. While her mixed bulk is middling at 65 physical and 63 magical, Brave Female Byleth is meant to be a strong offensive unit with a few tricks and tactics up her sleeves to handle some of her foes.
Inner Wellspring accelerates her special trigger by requiring one less attack to charge. At the start of her turn, if she is within two spaces of an ally, she gains a Null Follow-Up effect, stopping effects that prevent her from performing follow-ups and also negating her foe's ability to perform follow-ups so long as she has higher Spd than them. In addition, if her special is charged, she gains more charges per attack. If she initiates combat or is within two spaces of an ally, she gains +5 to her four core stats in combat and if she activates her special during or before combat, she gains more cooldown acceleration per attack. As such, Brave female Byleth practically always has her Special primed for combat.
Divine Pulse is her unique Brave Skill, which boosts damage by 25% of her Spd and reduces the damage from her foe's next attack by 75%. If she scores another attack, she adds another 20% of her Spd as flat true damage to her attack.
Attack Speed Catch grants a +7 Atk/Spd buff during combat to Brave Female Byleth if her foe is at 100% health at the start of combat or they have an active debuff like Panic or a stat debuff. If both conditions are met, she gains an additional +2 to both stats. Brave Female Byleth introduced Speed Preempt, which inflicts a -4 Spd drop on her foe. If a ranged foe with lower Spd than her initiates, she gains a Vantage effect, counterattacking before they make their first attack. Speed Resistance Hold inflicts a -4 Spd/Res debuff on foes within 3 spaces of her, pairing excellently with her Skill A.

Counters[]

Brave Female Byleth's clearest weakness is her vulnerability to melee ranged foes as she does not carry enough bulk to make the threat moot if they can get the jump on her. Some defensively built units, especially the likes of Ascended Fjorm, can outright absorb most of her damage and retaliate in full. As a flier she is vulnerable to Bows, however her Preempt skill limits this to either foes that can neutralize the change in combat order, such as through Hardy Bearing, or outright beat her in Spd. In general, her high Spd is her main condition that she needs to maintain to reap the maximum benefits of most of her skills, thus hampering it or outright exceeding her decently high Spd removes one of her main advantages.

Skill Inheritance[]

Female Byleth has an excellent kit with only her Support skill being empty. Reposition is an excellent filler for this slot, though Rallies can fill the need for higher scoring. She does not need to replace her default skill set, though she has high enough Spd to make Windsweep a viable replacement for her Skill B since she can focus all of her attention on Player turn tactics.

Base Set[]

Fallen Female Byleth rehashes her base form as a Sword Infantry unit but with tons of boosts that makes her a high impact and somewhat problematic opponent to deal with in a straightforward manner. Packing a blistering 47 neutral Spd, tied for the highest by the start of Book VIII, and a powerful 44 Atk, Fallen Female Byleth established herself as a high impact offensive unit. Her physical bulk is solid at 72 physical, however her 25 Res, scoring 65 for magical bulk, is a bit on the low side compared to some other units. Despite this, Fallen Female Byleth's worth it due to her superbly built base kit makes her one of the strongest units at the time.
Captain's Sword accelerates her Special charge, requiring one less attack to activate it. She has a Bulwark-like effect on foes depending on range, preventing melee foes from moving through a tile adjacent to her and preventing ranged foes from moving through spaces within two spaces of her. On certain maps, this can funnel units into her in order to gain access to her allies around her and can only be circumvented by Pass skills. At the start of combat, if she has at least 25% of her HP, she gains +5 to her four core stats and also neutralizes any visible stat bonuses during combat. After, she heals 7 HP. Finally, if her foe initiates combat and she has higher Spd, she gains Vantage, allowing her to counterattack before their first attack.
Divine Pulse boosts damage by 25% of her Spd and reduces damage of the first attack received by her foe by 75%. If she attacks again in the same round of combat, she deals 20% of her Spd as true damage to her foe.
Distant Attack Speed Solo combines both Distant Counter, allowing her to attack at range, and Attack Speed Solo with a +5 to her Atk/Spd if she is not adjacent to an ally. Close Call at its fourth tier inflicts Spd/Def-4 on her foe during combat. Her Spd is always treated as +7 when skill checks for comparisons in Spd stats. If her Spd is greater than her foe, she reduces damage from attacks during combat up to the difference between their Spd stats x5 and maximizing at a 50% reduction. After combat that she initiates, Fallen Female Byleth moves backwards from the direction she initiated combat. Time's Pulse in its fourth tier accelerates her special cooldown per attack if she starts her turn at maximum charge. If her special cooldown is at maximum value, she gains a free charge. With her 1 attack charge, she will always have her special charged before combat.

Counters[]

Fallen Female Byleth's kit is jam packed with skills that synergize with each other and cover a vast majority of her weaknesses, that there are only a small handful of true counters to her. While calculations of Spd are mostly taken care of by Close Call 4, she still suffers from any form of penalty and has no means of purging them on her own. Some Heroes can naturally outspeed her or, through a combination of boosts to themselves, can outstrip her naturally such as Ascended Nino and Harmonic Tea Ayra. Brave Attacks from high Spd units, like Legendary Elincia, can pile attacks on her, getting past her damage reductions. Finally, Ginnungagap's Ruler of Nihility disables her ability to counterattack, removing Divine Pulse's effects from the equation.

Skill Inheritance[]

Fallen Female Byleth's starting kit is built so well off of each other, that replacing any are likely less compatible compared to her default. Her only empty skill is her Support Skill, which Reposition fills splendidly.

Recruitment[]

While both Byleth and Jeralt can be recruited in all routes of the game, they cannot be recruited via Persuasion Strategies, but by accomplishing certain tasks that require some amount of planning. In all instances, the final step is to defeat their employer (Rodrigue in Scarlet Blaze, Randolph in Azure Gleam, and Fleche in Golden Wildfire) before Byleth can rendezvous with them. During this point, Byleth will almost instantly take allied forts that are impeding their march. However, defeating them mid transit is almost always a recruitment fail clause. Once this happens, Jeralt will ride to fight to his death, locking players out of the best version of their respective routes.

  • In Golden Wildfire, both Byleth and Jeralt can be recruited during Chapter 10's sole mission, "Assault on the Federation King", by ensuring Byleth does not reach Claude when he is doing his decoy mission objective (meaning dispatch the two enemy Swordmasters, Warriors, and Myson that appear to slow him down), otherwise Byleth and Jeralt will not join. Once Claude reaches safety and block access with a boulder, Fleche will open the doors to her fort; Byleth will then try to rendezvous with Fleche.
    • This route is the only route where Byleth can be defeated while in rendezvous and doing so will not cost the player the Eisners.
  • In Scarlet Blaze, both Byleth and Jeralt can be recruited during Chapter 10's main mission, "Subjugation of the Western Kingdom" by following these instructions:
    • Obtain the 30 Resource point-worth Resonant Lightning Strategy from the tent survey spot in western Duval territory and equip it during the Strategy portion of the fight.
    • Pressure Baron Mateus into surrendering by taking all the highlighted forts around him.
    • Rescue all three Sorcery Engineers from a Swordmaster ambush so the Resonant Lightning Strategy can be implemented.
    • Defeat Rodrigue before Byleth can rendezvous with the former Duke Fraldarius.
  • In Azure Gleam, both Byleth and Jeralt can be recruited during Chapter 12's main mission, "The Conquest of Hevring", by following these instructions:
    • Obtain the 30 Resource point-worth Locate Ambushers from the tent survey spot in Menja territory and equip it during the Strategy portion of the fight. This is more for first timers.
    • Use the strategy to make the strongholds containing ambushers will glow neon red. These strongholds are: Wooded Plateau, Decaying Ramparts, Crooked Highroad, Forest Byway, and Forest Highroad. At the same time, a green arrow will trace a path to the X that avoids all of these strongholds. Do not take any of the strongholds containing ambushers or the Eisners cannot be recruited.
    • Defeat Fleche upon arrival at the X and the ambushers, who reveal themselves once Fleche appears. Do not let any of the ambushers reach the Allied Base or the Eisners cannot be recruited.
    • Defeat Randolph before Byleth can rendezvous with their soon to be former employer.

Anna fates portrait
"Just a minute! The following section contains spoilers. Viewing it will cost a lot. Are you prepared to pay for it?"
Byleth - Wandering Flame (Silver Snow)
Byleth defeated those who slither in the dark and put down the crazed Immaculate One. In the aftermath of the loss of Fódlan's great leading figures, he/she ascended the throne as the first leader of the United Kingdom of Fódlan. In his/her heart lived the indelible hope that their efforts would one day yield an era in which the people knew true peace and the horrors of war were a hazy memory of the past.
Byleth - Ruler of Dawn (Verdant Wind)
Together, Byleth and Claude sent the Fell King, Nemesis, a foe from a bygone age, back to the flames of eternity from whence he came. Afterward, Claude left Fódlan, leaving Byleth to ascend the throne as the first leader of the United Kingdom of Fódlan. As he took his schemes and dreams and efforts to a far-off land, he hoped dearly that their joint efforts would one day allow for a world where all of humanity can co exist in peace and harmony, regardless of borders or bloodlines.
Male Byleth[]
Byleth and Linhardt
After ascending to the throne as the first leader of the United Kingdom of Fódlan, Byleth announced his marriage to Linhardt. The people of Fódlan placed high expectations on their leader's spouse, but to their consternation, Linhardt spent most of his time fishing, relaxing, and researching Crests. Fortunes turned when Byleth discovered a document, hidden away on Linhardt's desk, which provided a ground-breaking discovery. Cast unwittingly into prominence, Linhardt was put to work in earnest. In return for his service, he demanded longer naps in the company of his spouse.
Byleth and Bernadetta
After ascending the throne as the first leader of the United Kingdom of Fódlan, Byleth announced his marriage to Bernadetta. Many were concerned that the new leader of House Varley would do little more than hide, but she in fact followed the new king wherever he went and provided him with constant counsel. She never did overcome her shyness, however, and it is said that aspiring advisers who frightened her were quickly turned away. Because the ones she liked performed well in their service to the people, Bernadetta was widely believed to have a discerning eye.
Byleth and Dorothea
After ascending to the throne as the first leader of the United Kingdom of Fódlan, Byleth announced his marriage to Dorothea. The former songstress resolved to stay out of the public eye, keeping to herself and her family, but as Byleth worked tirelessly to restore Fódlan, she did offer advice from time to time. It is said that her experience growing up as a commoner provided a useful perspective. Many years later, her diary was uncovered, revealing the full extent of the happy life the couple shared. The love poems that they wrote to one another were published as a collection.
Byleth and Petra
After ascending the throne as the first leader of the United Kingdom of Fódlan, Byleth announced his marriage to Petra. In light of her love for her spouse and her unique position to act as a bridge between the two regions, Petra entrusted her homeland's throne to her family and remained in Fódlan. Together, the two worked hard to restore Fódlan and improve relations with Brigid. The foreign royal was initially met with skepticism, but in time, the people of Fódlan accepted and adored Petra. Thanks to their efforts, in the distant future, the two lands were eventually as one.
Byleth and Mercedes
Byleth announced his marriage to Mercedes shortly after becoming leader of the United Kingdom of Fódlan. Mercedes ensured that Fódlan paid special attention, in its rebuilding effort, to folks who had lost jobs and to children who had lost their families due to the war. The couple was said to mingle frequently among the people, working up a sweat right alongside them. They happily spent their lives ushering in a new era.
Byleth and Annette
After ascending the throne as the first leader of the United Kingdom of Fódlan, Byleth announced his marriage to Annette. His wife actively contributed to his endeavors, and it is said that her wisdom was heavily relied upon during Fódlan's restoration and development. Despite her lofty position, she was known to occasionally step in as a guest speaker at the Royal School of Sorcery, where she educated many renowned sages. Though her talents were widely respected, it is said she was always a bit accident-prone. Charming tales endure of her husband saving her from countless kitchen explosions, but it is unknown whether these are fact or purely fiction.
Byleth and Ingrid
Byleth announced his marriage to Ingrid shortly after becoming leader of the United Kingdom of Fódlan. Together they made great strides toward restoring Fódlan to its former glory and beyond. Though Ingrid contributed to the court in her position as queen, she also famously guarded her king in a physical capacity. Most well-known is how the "Warrior Queen" drew her own weapon to repel an assassin's blade meant for her husband, a tale which lived on in chivalric storybooks for generations.
Byleth and Lysithea
Byleth announced his engagement to Lysithea shortly after becoming leader of the United Kingdom of Fódlan. Before they were officially wed, she returned home, helped her father to restore Ordelia territory, and offered the land up to be governed directly by the new kingdom. Once the affairs of House Ordelia were in order, Lysithea finally married and became queen. Even without her Crests, she proved more than capable in the role, applying her great insight and intelligence toward a better Fódlan. When the rebuilding effort was complete, the couple and their children enjoyed long and peaceful lives.
Byleth and Marianne
Byleth announced his engagement to Marianne shortly after being named leader of the United Kingdom of Fódlan. Before they were officially wed, Marianne first returned home to prepare for the ceremony and to study oration and management under her adoptive father. She returned under the Great Tree Moon, and became queen of a restored Fódlan in a grand wedding. The kingdom experienced remarkable growth thereafter, and while Byleth became known as a leader of incredible wisdom, few people of the time understood the depth of the queen's influence.
Byleth and Hilda
Byleth announced his marriage to Hilda shortly after becoming leader of the United Kingdom of Fódlan. As queen, Hilda rarely took part in politics herself, but she nevertheless contributed greatly to the restoration of Fódlan by recommending exceptional people to influential positions. Her hobby of creating fashionable accessories also bore fruit, as her designs achieved widespread popularity, and she created the first artisan academy in Fódlan. The school produced many talented craftsmen, one of whom created a statue that expertly captured the king's delight at receiving the gift of a bracelet from the queen.
Byleth and Leonie
Byleth announced his marriage to Leonie shortly after becoming leader of the United Kingdom of Fódlan. Though she accepted the status of queen, Leonie disliked the pageantry of the position and refused to part with her weapons. She avoided court and instead founded the Jeralt Company, an elite group of soldiers hand-picked from the royal guard. They mostly busied themselves by hunting down bandits and monsters, but they also stopped the remnants of the Imperial army from organizing a revolt. It is rumored that one knight of rare skill who fought alongside Leonie in the Jeralt Company was none other than the king himself.
Byleth and Flayn
Byleth announced his marriage to Flayn shortly after becoming leader of the United Kingdom of Fódlan. Flayn did not get involved in government affairs, but instead focused on making frequent public appearances, where her calm and pleasant demeanor helped endear the new leaders to the people. When Fódlan was finally restored, the couple left the throne to their children and retired to a royal villa on the Rhodos Coast of western Fódlan. They spent their remaining years there in peace, fishing a great deal. It is said that no matter their age, they always retained a youthful appearance.
Byleth and Manuela
Byleth announced his marriage to Manuela shortly after becoming leader of the United Kingdom of Fódlan. Manuela lent her considerable talent and experience to the rebuilding effort, using personal connections she'd gained during her time as a songstress and teacher to assemble a team of talented people to govern. She became essential to the king's rule, and her skills as a physician kept him in good health for many years. The happiness of the couple and their children was plain to see on the faces that were immortalized in family portraits.
Byleth and Alois
After the war, Byleth ascended the throne of the United Kingdom of Fódlan, and Alois retired from the Knights of Seiros to serve the former professor. Alois became the new leader's right hand, and his duties in that respect kept him busily engaged all over Fódlan, giving all he had to support his reign. Alois' cheerful character was beloved by his subordinates, who rallied behind him to create the most numerous order of knights in all Fódlan. It is said that Byleth relied on Alois as though he were his own father.
Byleth and Catherine
Byleth announced his marriage to Catherine shortly after becoming leader of the United Kingdom of Fódlan. While the king focused on the rebuilding effort, Catherine worked as his bodyguard, and when the situation called for military force, she mobilized the troops and went to battle. Under her watchful eye, Fódlan entered a new era of peace. A common saying among the people was that the king of Fódlan had two weapons: the Sword of the Creator, and his fearsome wife.
Byleth and Shamir
Byleth announced his marriage to Shamir shortly after becoming leader of the United Kingdom of Fódlan. While the king focused on the rebuilding effort, Shamir became his bodyguard and confidant. She even acted as captain of the royal guard, and became known as a watchful and trustworthy queen. As a couple, their daily lives were busy indeed, and both were famously taciturn, but it is said they cherished their quiet time together - especially once they began to have children.
Byleth and Rhea (Silver Snow only)
After finally saving both Fódlan and Rhea from Crisis, Byleth ascended the throne as the first leader of the United Kingdom of Fódlan. From his temporary residence at Garreg Mach Monastery, he endeavored to restore and develop Fódlan. Having narrowly escaped death, Rhea took time to recover her strength before returning to her role as archbishop. Upon her return, she applied herself to rehabilitating the church and helping those who had suffered because of the war. Thereafter, the two worked closely to forge new policies and achieve progress for Fódlan. The pair's collective work came to be thought of as nothing short of miraculous.
Byleth and Yuri
As the new leader of the United Kingdom of Fódlan, Byleth worked tirelessly to reform and rebuild in the aftermath of a devastating war. Constantly at his side during that time was his husband, Yuri, who's policy proposals led, time and again, to better education and opportunities for the less fortunate. After working to ensure a bright and prosperous future for Fódlan, the couple stepped back from the public eye vanished from official record. Curiously, informal notes and letters from friend suggested that the pair was extraordinary long-lived and their youth was untouched by the passage of time.
Byleth and Constance
After ascending to the throne as the first leader of the United Kingdom of Fódlan, Byleth announced his marriage to Constance, who was given peerage for her service in the war and permitted to revive House Nuvelle. Praised for her innovative talent, she rapidly rose to prominence in the new era, and her house came to be relied upon as a valued leader in magical research and development for generations to come. She was not without detractors, however. Jealous rumors persisted throughout her life that the rays of the sun compelled her to retreat into hiding, threatening to reveal her monstrous true form.
Byleth and Hapi
After ascending to the throne as the first leader of the United Kingdom of Fódlan, Byleth announced his marriage to Hapi. Her disquieting lineage earned her more than her fair share of detractors, but over time, as the royal couple restored Fódlan together, the people came to appreciate her competence and taciturn wit. Some years later, when those who slither in the dark emerged to threaten Fódlan once again, it is said that Hapi's strength was instrumental in dealing with them.
Female Byleth[]
Byleth and Claude (Verdant Wind only)
After ascending the throne as the first leader of the United Kingdom of Fódlan, Byleth sought to rebuild the war-torn towns and villages and to help guide the reformation of the Church of Seiros. After a few months of peace, remnants of the Imperial Army joined with those who slither in the dark and marched upon the capital city of Derdriu. The new kingdom lacked the power to repel the invaders, but when defeat seemed imminent, a battle cry rang out from the east. Claude, the newly-crowned King of Almyra, led a mighty army that broke through the rebel forces with ease. This show of solidarity forever altered the course of history, heralding a new age of unity.
Byleth and Ferdinand
After ascending to the throne as the first leader of the United Kingdom of Fódlan, Byleth announced her marriage to Ferdinand, who had assumed his inherited position as Duke Aegir. Ferdinand overcame a slew of obstacles to reform his territory and that of House Hrym. He chose not to accept an official position in service to Byleth, instead advising her only informally as a spouse. History books extol Ferdinand's success as a lord of his territories, but make no mention of his marriage. Thus, half of his life's work is lost to time.
Byleth and Linhardt
After ascending to the throne as the first leader of the United Kingdom of Fódlan, Byleth announced her marriage to Linhardt. The people of Fódlan placed high expectations on their leader's spouse, but to their consternation, Linhardt spent most of his time fishing, relaxing, and researching Crests. Fortunes turned when Byleth discovered a document, hidden away on Linhardt's desk, which provided a ground-breaking discovery. Cast unwittingly into prominence, Linhardt was put to work in earnest. In return for his service, he demanded longer naps in the company of his spouse.
Byleth and Caspar
After ascending to the throne as the first leader of the United Kingdom of Fódlan, Byleth announced her marriage to Caspar. But Caspar, never one to sit still for long, set out on a journey of self-discovery. He traveled to every corner of Fódlan and even took Byleth along on occasion. It is said that he got into mischief at every turn, and that his wife sometimes had to invoke her authority to defuse the situation, but that the victims of his antics always came away more amused than harmed or offended in the end. The stories of their travels were remembered fondly for generations.
Byleth and Dorothea
After ascending to the throne as the first leader of the United Kingdom of Fódlan, Byleth announced her marriage to Dorothea. The former songstress resolved to stay out of the public eye, keeping to herself and her family, but as Byleth worked tirelessly to restore Fódlan, she did offer advice from time to time. It is said that her experience growing up as a commoner provided a useful perspective. Many years later, her diary was uncovered, revealing the full extent of the happy life the couple shared. The love poems that they wrote to one another were published as a collection.
Byleth and Felix
Byleth married Felix almost immediately after ascending the throne of the United Kingdom of Fódlan. When it came to matters of governance, Felix often took on duties that would have required his wife to dirty her hands and thus came to be called The Royal Sword. After they accomplished all they had set out to do, the couple left the rule of Fódlan to the next generation, disappearing into obscurity with blades in hand. Thereafter, history only provides unconfirmed reports of a pair of traveling mercenaries who possessed unmatched strength and skill.
Byleth and Ashe
When Byleth ascended the throne of the United Kingdom of Fódlan, Ashe served the new leader faithfully - first as a knight aide, and later as a husband. The queen, with help from the Church of Seiros, put much toward the rebuilding effort with particular attention paid to relief for orphans in the form of food, beds, and even schooling. It is said that these compassionate deeds were all Ashe's suggestions, but the modest knight always gave the credit to his beloved wife.
Byleth and Sylvain
After ascending the throne as the first leader of the United Kingdom of Fódlan, Byleth announced her marriage to Sylvain, who had become the new Margrave Gautier. Sylvain was a valued ally who assisted his wife in her new role, both publicly and privately. Most of all, it is said that his cunning manner of speech was a great asset for fostering relations between the Church of Seiros, Fódlan, and surrounding regions. Though known as a philanderer in youth, Sylvain happily settled down after marriage and became a gentle and devoted husband and father. The two had many children whom they doted on equally, regardless of whether or not they bore a Crest.
Byleth and Mercedes
Byleth announced her marriage to Mercedes shortly after becoming leader of the United Kingdom of Fódlan.

Byleth and Lorenz
Byleth announced her marriage to Lorenz shortly after becoming leader of the United Kingdom of Fódlan. Lorenz took equally well to his dual roles as the queen's husband and the leader of House Gloucester, working simultaneously to restore his own territory and to advance the development of Fódlan at large. Because his policies were of particular benefit to the commonfolk, he was well loved, and came to be called the Lord of Roses. After many years of peace, Lorenz grew ill and withdrew from the public eye. The queen followed, entrusting the throne to the prince. It is said that he was the spitting image of his father.
Byleth and Raphael

The couple was long remembered, even after they stepped back from the public eye, thanks to portraits painted by the court's renowned artist: Raphael's sister, Maya.
Byleth and Ignatz
Byleth announced her marriage to Ignatz shorty after becoming the leader of the United Kingdom of Fódlan. Ignatz supported the restoration of Fódlan as Queen's spouse, but became better known for his skill with a paintbrush. He donated beautiful portraits and landscapes to churches all over the kingdom, and it is said that his works provided great comfort to those touched by the war. His most famous price, entitled Descent of the Goddess, depicted the eponymous deity descending from the heavens to lead the people. Those who knew the queen often remarked that her face must have been used as a reference.
Byleth and Seteth
After ascending the throne as the first queen of the United Kingdom of Fódlan, Byleth appointed Seteth as her prime minister. As they set about the grand task of restoring Fódlan, the prime minister's strictness combined with the queen's magnanimity won the people over easily. Their personalities complemented one another perfectly in dealings with obstinate lords. When their long work was done, they finally announced their marriage, to the shock and delight of their subjects. The people considered themselves truly blessed to be governed by such a union.
Byleth and Hanneman
Byleth announced her marriage to Hanneman shortly after becoming leader of the United Kingdom of Fódlan. Hanneman provided counsel to the queen as she worked to restore Fódlan, but his goal remained to determine the workings of the Crests and to do away with the inequality caused by them. To that end, his research resulted in magical tools which could be used even without the aid of Crests. The queen made good use of these tools, and they soon became a cornerstone for continued progress.
Byleth and Alois
After the war, Byleth ascended the throne of the United Kingdom of Fódlan, and Alois retired from the Knights of Seiros to serve the former professor. Alois became the new leader's right hand, and his duties in that respect kept him busily engaged all over Fódlan, giving all he had to support her reign. Alois' cheerful character was beloved by his subordinates, who rallied behind him to create the most numerous order of knights in all Fódlan. It is said that Byleth relied on Alois as though he were her own father.
Byleth and Cyril
Byleth declared the founding of the United Kingdom of Fódlan at Garreg Mach and ascended the throne as its first leader. Cyril served as a chamberlain, supervising all general affairs. With the expansion of the kingdom, it was eventually decided that the queen would move to a new royal capital. Cyril wished to accompany her, but was ordered to enroll in the newly reopened Officers Academy. Though reluctant, he complied. A year later, after consistently demonstrating great wisdom and maturity, he won the queen's heart, and they announced their abrupt marriage. The move surprised many, but no one was as shocked as Cyril himself was pleased.

From her temporary residence at Garreg Mach Monastery, she endeavored to restore and develop Fódlan.

Constantly at her side during that time was her husband, Yuri, who's policy proposals led, time and again, to better education and opportunities for the less fortunate, a legacy that was later taken up by the couple's children. A trove of love letters, uncovered many years later, revealed him she called him by an entirely different name in private. Scholars never learned why.
Byleth and Balthus
After ascending to the throne as the first leader of the United Kingdom of Fódlan, Byleth announced her marriage to Balthus. The people were reluctant to accept this union at first, considering his reputation, but his natural charisma in speeches and his ability to exceed expectations eventually won their blessing. Though mostly noted for his strength and dedication as a bodyguard, Balthus also provided counsel. It is said that many civil and diplomatic reforms owe their origins to his advice.

It is said that Alois was so overcome with emotion on the archbishop's wedding day that his weeping could be heard through the applause.
Byleth and Catherine
Byleth announced his marriage to Catherine shortly after becoming archbishop of the Church of Seiros. While the archbishop focused on the rebuilding effort, Catherine worked as his bodyguard, and when the situation called for military force, she mobilized the troops and went to battle.

Byleth and Shamir
Byleth announced his marriage to Shamir shortly after being named archbishop of the Church of Seiros. While the archbishop focused on the rebuilding effort, Shamir became his bodyguard and confidant.

As the new Archbishop of the Church of Seiros, Byleth worked tirelessly to reform and rebuild in the aftermath of a devastating war.

Curiously, informal notes and letters from friends suggested that the pair was extraordinary long-lived and their youth was untouched by the passage of time.
Byleth and Constance
After taking his place as the new archbishop of the Church of Seiros, Byleth announced his marriage to Constance, who was given peerage for her service in war and permitted to revive House Nuvelle.

Byleth and Hapi
After becoming the new Archbishop of the Church of Seiros, Byleth announced his marriage to Hapi. Her disquieting lineage earned her more than her fair share of detractors, but over time, as the royal couple restored Fódlan together, the people came to appreciate her competence and taciturn wit. Some years later, when those who slither in the dark emerged to threaten Fódlan once again, it is said that Hapi's strength was instrumental in dealing with them.

Byleth and Dimitri
Paired with the end of the war, the joyous marriage of Byleth, the newly-appointed archbishop, and Dimitri, the newly-crowned king of Faerghus, gave the people of Fódlan much to celebrate. The two were devoted to improving life for the people and to seeking greater wisdom in order to reform the government and the church from the inside out. As leaders of church and state respectively, at times they engaged in heated debate.

They remained as such for the rest of their days.
Byleth and Dedue
A year after Byleth was appointed to succeed Rhea as the new archbishop, she announced her marriage to Dedue, who had resigned his position as the king's vassal.

Byleth and Ferdinand
After taking her place as the new archbishop of the Church of Seiros, Byleth announced her marriage to Ferdinand, who had assumed his place as Duke Aegir.

Byleth and Linhardt
After ascending to the throne as the first leader of the United Kingdom of Fódlan, Byleth announced her marriage to Linhardt. The people of Fódlan placed high expectations on their leader's spouse, but to their consternation, Linhardt spent most of his time fishing, relaxing, and researching Crests. Fortunes turned when Byleth discovered a document, hidden away on Linhardt's desk, which provided a ground-breaking discovery. Cast unwittingly into prominence, Linhardt was put to work in earnest. In return for his service, he demanded longer naps in the company of his spouse.

The stories of their travels were remembered fondly for generations.
Byleth and Dorothea
After taking on the role of archbishop of the Church of Seiros, Byleth announced her marriage to Dorothea.

The love poems that they wrote to one another were published as a collection.

Attendants remarked that the smiles they wore on their faces during these bouts were never seen elsewhere.
Byleth and Ashe
When Byleth became the new archbishop of the Church of Seiros, Ashe served her faithfully-first as a knight and aide, and later as a husband. With help from Faerghus, the archbishop put much toward the rebuilding effort with particular attention paid to relief for orphans in the form of food, beds, and even schooling. It is said that these compassionate deeds were all Ashe's suggestions, but the modest knight always gave the credit to his beloved wife.
Byleth and Sylvain
After becoming the new archbishop of the Church of Seiros, Byleth announced her marriage to Sylvain, heir to House Gautier.

It is said that those who knew him in his youth wondered what sort of spell the archbishop had cast on him.

The couple was said to mingle frequently among the people, working up a sweat right alongside them. They happily spent their lives ushering in a new era.
Byleth and Lorenz
Byleth announced her marriage to Lorenz shortly after being named archbishop of the Church of Seiros. Lorenz took equally well to his dual roles as the archbishop's husband and the leader of House Gloucester, working simultaneously to restore his own territory and to support the church's efforts to restore Fódlan at large. Because his policies were of particular benefit to the commonfolk, he was well loved, and the church's authority was restored as a result.

His most famous piece, entitled Descent of the Goddess, depicted the eponymous deity descending from the heavens to lead the people. Those who knew the archbishop often remarked that her face must have been used as a reference.
Byleth and Seteth
After ascending the throne as the first queen of the United Kingdom of Fódlan, Byleth appointed Seteth as her prime minister. As they set about the grand task of restoring Fódlan, the prime minister's strictness combined with the queen's magnanimity won the people over easily.

When their long work was done, they finally announced their marriage, to the shock and delight of their subjects. The people considered themselves truly blessed to be governed by such a union.
Byleth and Hanneman
Byleth announced her marriage to Hanneman shortly after being named archbishop of the Church of Seiros. Hanneman provided counsel to the archbishop as she worked to restore the church, but his goal remained to determine the workings of the Crests, and to do away with the inequality caused by them. To that end, his research resulted in magical tools which could be used even without the aid of Crests. The archbishop made good use of these tools, and they soon became a cornerstone for continued progress.
Byleth and Gilbert
When Byleth took on the role of archbishop in Rhea's place, she devoted herself to official business as the new leader of the Church of Seiros.

It is said that she continued to call upon Gustave for instruction and advice well into his retirement.

His cheerful character inspired those under his command, unifying the Knights of Seiros in a way they had never been before.

Byleth and Cyril
Byleth took on the role of archbishop of the Church of Seiros, and Cyril served her in all things, just as he had served Rhea. As Fódlan stabilized, and the rebuilding effort came to an end, the Officers Academy finally reopened, and the archbishop directed Cyril to enroll there as a student. A year later, after consistently demonstrating great wisdom and maturity, he won the archbishop's heart, and they announced their abrupt marriage. The move surprised many, but no one was as shocked as Cyril himself was pleased.
Byleth and Yuri
As the new Archbishop of the Church of Seiros, Byleth worked tirelessly to reform and rebuild in the aftermath of a devastating war. Constantly at her side during that time was her husband, Yuri, whose policy proposals led, time and again, to better education and opportunities for the less fortunate—a legacy that was later taken up by the couple's children. A trove of their love letters, uncovered many years later, revealed that she called him by an entirely different name in private. Scholars have never learned why.
Byleth and Balthus
After taking her place as the new archbishop of the Church of Seiros, Byleth announced her marriage to Balthus. The people were reluctant to accept this union at first, considering his reputation, but his natural charisma in speeches and his ability to exceed expectations eventually won their blessing.

There they took in and raised children who had lost their families in the war, regardless of their blood or circumstances of birth. It is said that Mercedes was never happier than when she was surrounded by smiling children, free of all worry.

Almost as soon as Byleth and Balthus finished their lively wedding celebration, the battle with those who slither in the dark began in earnest. Leading from the front lines, the couple drove the enemy back again and again, causing such carnage on the battlefield that even their Imperial allies and subordinates were intimidated. After hostilities came to an end, their names faded from official historical records but persisted in folk tales. Of the stories that spread to every corner of Fódlan and survive to this day, the most prominent one features criminals who threaten to abduct a traveler's wife. The traveler laughs and wishes them the best of luck.

“Byleth Recruits... Byleth!”
—Female Byleth's introduction blurb.

Byleth appears as the fifth downloadable fighter for Super Smash Bros. Ultimate as the final fighter for Fighter's Pass Volume 1. Byleth was originally confirmed during a presentation on January 16, 2020 before being released twelve days later, on January 28, 2020.[1] Included alongside the purchase of Byleth is the stage, Garreg Mach Monastery, as well as two fighter spirits of Byleth, in their male and female forms respectively.

Described by Masahiro Sakurai as a distance oriented character, Byleth excels in medium-to-long range combat, but is not as effective at close range in most instances, which is mainly due to their low mobility. Byleth retains the Sword of the Creator, used particularly during their standard attack, tilt attacks, up smash, and up aerial, and the Sword of the Creator retains its ability to transform into a whip sword, giving the characters great range. The sword is primarily used in their up smash, up aerial, and up special, as well as their neutral attack, tilt attacks, dash attack, and throws. All of Byleth's special moves involve the other legendary weapons of Fire Emblem: Three Houses: the Failnaught for their standard special and standard aerial, the Areadbhar for their side special, forward aerial, and back aerial; and Aymr for their down smash and down aerial.

Byleth's color palettes are divided between male and female variations, and include Dimitri and Claude colors for male Byleth and Edelgard and Sothis colors for female Byleth. Their final color palettes for both genders have Byleth in their story transformation when merged with Sothis.

Byleth has average weight, being heavier than Pit, Wii Fit Trainer, Dark Pit, and Pokémon Trainer's Ivysaur, but lighter than Mario, Dr. Mario, Corrin, and Pyra, while having the same weight as Luigi and Shulk.

Byleth's Classic Mode route is titled "A Heroic Legacy." Similarly to Lucina and Young Link, Byleth's Classic Mode involves other Fire Emblem characters in the order their games of origin were released. Like with Ryu and Terry, all matches in Byleth's Classic Mode route are Stamina battles. Similarly to Lucina and Young Link, Byleth's Classic Mode involves other Fire Emblem characters in the order their games of origin were released. Like with Ryu and Terry, all matches in Byleth's Classic Mode route are Stamina battles.

Zach Aguilar and Yūsuke Kobayashi reprise their roles as male Byleth, while Jeannie Tirado and Shizuka Ito reprise their roles as female Byleth.

Palutena's Guidance[]

Byleth shares this stock conversation with all other Fighters Pass characters. It was originally used in Super Smash Bros. for Wii U for every downloadable fighter: Mewtwo, Lucas, Roy, Ryu, Cloud, Corrin, and Bayonetta.

  • Pit: Who is THAT?
  • Palutena: I have no data on this fighter. I can't believe it!
  • Viridi: It must be an intruder from another dimension!
  • Pit: Whoever it is, the goal remains the same: to fight and win!

Official website description[]

Byleth is coming to the Super Smash Bros. Ultimate game as a new playable fighter! This iconic fighter is the fifth fighter in the Super Smash Bros. Ultimate Fighters Pass. Using the Heroes’ Relics and the Sword of the Creator, represent the three houses and realize their full potential.

Special Moveset[]

All of Byleth's special moves except their Final Smash shares a title with one of the weapons.

  • Neutral Special: Failnaught: Byleth briefly prepares an arrow before firing it at an opponent. Byleth can charge the bow by holding down the Special button, though the charge cannot be stored so Byleth will automatically fire. At full charge, the arrow gains additional damage, speed, and knockback, similarly to how Link's Bow functions. Byleth may change direction and cancel the move using the shield button mid charge unless they are preparing to fire the fully charged shot, in which they must fire it.
  • Side Special: Areadbhar: Byleth swings Areadbhar upward, attacking opponents in its range. The move has excellent reach and applies Areadbhar's property of dealing more damage if enemies are hit by the tip of the Lance. If the Smash attack is input while charging, Byleth will move slightly forward during the move's execution. The move can also be angled.
  • Up Special: Sword of the Creator: Byleth extends the Sword of the Creator into a whip in an upward diagonal angle. The move is similar to Joker's up special, but if it contacts an enemy, Byleth will reel themselves into their aerial opponent before spiking them into the ground, and they can also jump off of the character. If the move makes contact before 45%, the opponent will be launched upward instead. If the move makes contact with a ledge, Byleth will pull themselves to it, and if it makes contact to the wall of the stage, Byleth will pull themselves up to it and jump off, from where they can grapple again.
  • Down Special: Aymr: Byleth briefly winds up Aymr before smashing it into the ground. Halfway through the windup, Byleth has super armor and will not flinch from an attack except for grab moves. Although it is a strong, but slow, overhead swing attack, the move has excellent damage and knockback for opponents who are hit by the axe, however a small area around the axe's impact will also inflict less damage and knockback to opponents. Byleth can turn around the move at the expense of more lag, and during its startup can drop from platforms.
  • Final Smash: Progenitor God Ruptured Heaven: Byleth uses the Sword of the Creator to slash a small area in front of them. Sothis appears in the background and grants Byleth additional power as they perform Ruptured Heaven on the opponents hit by the initial slash.

Byleth is illustrated in the trading card game Fire Emblem Cipher with the following cards:

Etymology[]

Byleth (/baɪlɛθ/) is a variation of Beleth, a Goetic demon and king of Hell. According to Pseudomonarchia Daemonum, Ham, Noah's son, was the first in invoking him after the flood, and wrote a book on mathematics with his help. This alludes to Byleth's nickname "The Ashen Demon" for their emotionless countenance on the battlefield.

Eisner (/ˈaɪznər/), Byleth's surname, is a German name related to various iron-working occupations such as smithing.

Trivia[]

  • Byleth's default name in Japanese differs slightly between genders, as a male Byleth is spelled "ベレト" (Bereto), while the female is "ベレス" (Beresu).
    • Byleth's name shares this difference in the Asian localizations. (ZH: "貝雷特" (pronounced Bèi Léi Tè, as in Bylet) / "貝雷絲" (pronounced Bèi Léi Sī, as in Byleth); KR:"벨레트" (pronounced Belleteu, as in Bylet) / "벨레스" (pronounced Belleseu, as in Byleth))
  • Three Houses updated on September 10th 2019 to change Male Byleth's voice actor from Chris Niosi to Zach Aguilar. This is the only instance where a character's voice actor was changed post release in a main series Fire Emblem title.
  • While the player chooses Byleth's birthday, the default birthdate is 20th of the Horsebow Moon 1159 (September 20th), a significant date in the story and reinforced by information from Jeralt's journal.
  • If, during a New Game+, the Holy Tomb is visited via the amiibo Gazebo at any point after Chapter 10, the opposite gender version of Byleth will be found there. They can be talked to, but will only speak in ellipses.
  • Byleth is the first Avatar character to have a defined difference in height between genders.
  • Female Byleth is the only unit to be capable of S-Supporting all three Lord characters and has 26 S-Supports compared to Male Byleth's 24.
  • Byleth shares some notable similarities with Ike.
    • Both are mercenaries guided by their father, a famous former knight, who is then murdered, spurring them toward action against the killers.
    • Both were raised with a false history of their own pasts.
    • Both became inactive for an amount of time but returned in order to stop a war as the commander of an army.
    • They both have to face former allies, and receive divine powers.
    • Both are big eaters.
    • Their signature weapons, Ragnell and the Sword of the Creator, both stand out as non-magical swords with range 1-2.
  • The male version of Byleth is the first, and so far the only character in Heroes to become available through recognition of another game's data. At the launch of Three Houses, Heroes players that played both games on the same Nintendo Account would have received a free Byleth: Tested Professor unit if they registered their copy of Three Houses for gold points. This offer was active through one year after the game's launch, likely because gold points can only be earned from physical copies of Switch games within the first year of their release.
  • Byleth is the first Avatar to fully appear in animated cutscenes without being obscured in some manner. This is possible due to Byleth's lack of customizable physical features.
  • Byleth is the first Avatar to have dialogue options in conversations.
  • Byleth is the first and only Avatar character to be referred with neutral pronouns in the game. Because the game is fully voiced, the use of titles and neutral pronouns allows the same dialogue to be used for both genders of Byleth without the need to record separate lines. Gendered pronouns are used in the game's epilogue and some tutorial text, which are not voiced.
  • Byleth is the first Avatar character since Mark to not feature a customizable appearance. Their male and female designs are fixed and cannot be edited by the player.
  • Byleth, unlike other playable characters in Three Houses, possesses a unique color palette for all of their available classes instead of sharing a palette with another character—primarily blackish-blue with purple accents.
  • Byleth is the only member of the first Fighters Pass who is not a third-party character, as well as the only one from an already represented series, and the second DLC character in the game overall to be so, following Piranha Plant.
    • Byleth's Dimitri costume is the only one where the dagger is recolored. The color scheme matches the dagger Dimitri gave to Edelgard.
    • Byleth is also the only fighter to have made their overall debut after the release of Super Smash Bros. Ultimate, having first appeared in 2019.
  • Byleth is currently the only fighter in the Super Smash Bros. series who has two taglines, largely because of both their being composed of two characters, and their technically having different names in Japan (the male Byleth being known as "Bereto" and the female Byleth being known as "Beresu").
  • Byleth's death quote is the same as Azura's voiced defeat quote in Fates.
  • Byleth is the second protagonist whose defeat in Casual Mode doesn't cause a Game Over. The first was Corrin.
  • Byleth's artworks for Three Houses depict them wielding the Sword of the Creator.
  • Byleth was implied to be 20/21, but with the Cindered Shadows story released, it's been confirmed that they're indeed of said age by Sitri's date of death, which has been added on her grave.
  • In Byleth's trailer for Super Smash Bros. Ultimate, Sothis gives them the Heroes' Relics used by the house leaders, Aymr included, and while that's only a story mechanic, it's ironic considering that the axe shouldn't have been created yet.
  • The male Byleth amiibo is the only Fire Emblem amiibo that lacks any specific uses in the Fire Emblem series. Every other Fire Emblem amiibo has some type of functionality in Fire Emblem: Three Houses and Fire Emblem Warriors.
  • In a survey conducted by Nintendo DREAM Magazine, Female Byleth placed 3rd with 17.7% of the vote overall and ranked 4th with 16.6% among those who completed the game in the character popularity poll for Three Houses.

    • In the same poll, Male Byleth placed 7th among those who completed the game with 124 points.
  • In the fourth survey conducted by Nintendo DREAM Magazine, Female Byleth placed 3rd in the character popularity poll for Three Houses. The male-female vote ratio was 1:4. She ranked 3rd among those who completed the game with 137 points.

  • Byleth is the first Avatar unit to have both of their genders appear as Legendary Heroes in Heroes.
    • In addition, they have the shortest waiting time for both of their genders to appear as Legendary Heroes with a waiting time of 5 months and 24 days.
  • In Three Hopes, Byleth has the most extremely skewed favorite/disliked food ratio between all units, liking 28 of the 32 dishes available and disliking 0.
  • Byleth shares some similarities to Alear:
    • Both lost their biological mother.
    • Their appearance cannot be altered.
    • Both were emotionless and stoic before the events of the game.
  • The number thirteen seems to be a recurring theme for Byleth. Byleth is the thirteenth host of Sothis. The demon of Byleth's namesake, Beleth, is the thirteenth demon listed in "The Lesser Key of Solomon". Byleth starts out with a base Strength of thirteen in both Heroes and Three Houses. Byleth is the thirteenth newcomer to Super Smash Bros. Ultimate. The maximum amount of Divine Pulse charges Byleth can use in Three Houses is also thirteen.
