Julius is the main antagonist in the second generation of Fire Emblem: Genealogy of the Holy War. He is the son of Arvis and Deirdre, who were deliberately brought together by Manfroy in order to ensure that they would deliver the reincarnation of Loptous as their offspring. He is also the twin brother of Julia, the half-brother of Saias and Seliph, and the grandson of Victor, Cigyun and Kurth. Through the blood of Heim, he is a distant relative of Linoan. Through the blood of Fjalar, he is a distant relative of Hilda and her children, Ishtore and Ishtar.
