Julialius

Julialius is the family ship between Julia and Julius from the Fire Emblem fandom.

Canon
Julia and Julius are two characters from Fire Emblem Genealogy of The Holy War. Julia and Julius are the twin children of Deirdre and Arvis. They grew up at Belhalla Castle as their parents where the emperor and the empress of Grannvale. According to Julia, Julius was originally a kind and caring person but he changed when he received the Loptyr tome. Julius's birth was orchestrated by the Loptyr cult that manipulated Arvis and Deirdre to marry in order to have them give birth to a child with a major Loptyr Holy Blood that could serve as a vessel for their dark god Loptyr. The leader of the cult, Manfroy, gave Julius the Tome of Loptyr which corrupted him. Julius then decided to kill all bearers of the Naga Holy Blood since the Naga tome has to power to fight Loptyr blood bearers. This included his own mother and sister. When Julius attacked them Deirdre used the last of her forces to warp Julia away before being killed by her own son. However, Julia became amnesiac because of the trauma. She is found by Lewyn who take care of her until they meet Seliph, the siblings' half-brother fathered by a warrior named Sigurd. He entrusts Julia to Seliph and she join the liberation army.

Julia fought the Grannvale army without remembering that the dark prince Julius is her brother. When the liberation army reaches the Miletos District, Manfroy kidnaps Julia, and locks her in the Chalphy Castle dungeon, where she regains her memory and reunites with her father. In a conversation with him, Julia explains that she would have preferred to not remember Julius killing their mother. Later Manfroy, takes Julia to Julius while Arvis is left powerless. After Arvis's death, the liberation army continued its advance. Julius asks Manfroy to bring Julia to him, to which she says that she remembers the night when Julius changed that her beloved brother died that day, and that the man in front of her is a demon who is only her brother in name. Since Julia is able to bear the Naga tome, Julius wanted to kill her, but Manfroy convinced him to instead use her as a weapon.

Seliph learned by Lewyn of Julia's heritage and becomes determined to free her. Manfroy uses his dark magic to control Julia and forces her to fight the liberation army. The liberation army triumphs, killing Manfroy in the battle, and Seliph is able to break his control by talking to her. They then go to Velthomer and find the Naga tome that was hidden by Arvis. When Julia fights Julius, he is surprised to see her and says that Manfroy made a mistake. Julia use to Naga tome against him to negate the effect of the Loptyr tome. When she kills him, his last words are for Naga which imply that it's not Julius talking but Loptyr. After the war Seliph becomes King of Grannvale, regardless of who is her lover (and if she has one) Julia will stay at Belhalla to watch over her half-brother.

Fanon
Since Genealogy of the Holy War was has yet to be released outside Japan and that Julia and Julius are mortal enemies for the majority of their live not many fanworks show their relationship. Since it's hard to defeat Julius without Julia and her Naga tome many fanarts that depict the final battle of Fire Emblem 4 show Julia fighting Julius. Some fanworks shown Julia and Julius as children before his possession, some others shown Julia (sometime alongside Seliph) mourning Julius after the war. A relatively popular AU swap Julia and Julius holy blood and role (and sometime their hair color). Since in Heroes they can both be summoned some fanworks show them together in Askr (sometime in the same team). Their are also often depicted with other members of their family like Saias, Arvis, Deirdre and Seliph. Some other fanworks show them meeting with Sigurd who is their step-father.
