Iuchar

Iuchar is a character from Fire Emblem: Genealogy of the Holy War. He is the brother of Iucharba and Brian, the son of Danann, the half-nephew of Lex, and the grandson of Lombard. He is in command of Isaach Castle during the second part of the game, whereby he is in love with Larcei/Creidne. He may be recruited by Larcei/Creidne, but doing so will essentially cause Iucharba to continue campaigning against the army out of jealousy.
