Navarre

Nabarl (Sometimes translated Nabaaru or Navarre) is a stoic mercenary known as the Crimson Fencer and infamous for his Kill Sword, often working for banditry for unknown reasons. He was first assigned to chase after Rena and Julian, but changed his mind when Sheeda asks him to join, which he did. Nabarl also holds a policy not to harm women he encounters.

In the second book, he returns to banditry again and encounters the dancer Fina. After hearing that the Aritian army approaches him, Nabarl once again defects and protected Fina along the way. He helps Marth out of respect from the last quest, but once again vanishes once the quest is over.

Archtype
Nabarl also jump started a trend of Fire Emblem characters as a dangerous enemy who can be convinced to join and comes up with something that increases Critical rate, such as the Kill Sword. His character archetype later evolves into the Myrmidon class in latter Fire Emblem games.
