Anri

Anri is the Hero that slew Medeus. When Medeus and his Doluna Empire began their conquest of the continent, Anri, then just a Altean peasant living with his two brothers, met Princess Artemis of Akaneia, who was hiding from the Dolunian forces in Altea. Anri and Artemis fell in love and Anri left to the Ice Dragon's Temple to claim the Falchion in order to protect her, guided there by Gotoh. Just when all hope seemed lost, Anri returned and slew Medeus using the Falchion. He was later crowned the first king of Altea, although he never married due to Artemis being forced into marriage with Duke Cartas, another Akaneian general in the war who wielded the Fire Emblem. Because of this, after his death an issue of which of his two brothers would inherit the kingdom broke out, with his brother Marcelus becoming the king of Altea and the other brother forming the kingdom of Gra.

He, like Marth, has exquisite electric blue hair and wears the same crown as Marth wears when he's still a prince.
