Lelouch vi Britannia (Flame Icejin universe)

Lelouch vi Britannia (ルルーシュ・ヴィ・ブリタニア, Rurūshu Vi Buritania) is a character that appears in Ice Jeweler and Flame Icejin: The New Frontier.

Ice Jeweler
His story begins when his adopted brother, Rolo Haliburton, lost his parents to gunfire. His father, Charles zi Britannia, left to investigate, inheriting the ability of giving others complete obedience. Seven years later, Lelouch, now a high school student at Ashford Academy, is still living with his mother, Marianne vi Britannia, his younger fourteen-year-old sister, Nunnally vi Britannia, and his adoptive brother. He is close friends with the Fullmetal Alchemist, Edward Eric, and his brother, Alphonse. When Hisui Diamond and her friends arrived at his home, Lelouch volentiered to teach Hisui how to use her Geass and keep it under control, so it wouldn't go under Geass Runaway.

Season Four/The Geass Boy and the Negaverse
In Flame Icejin: The New Frontier, it is revealed that, sometime after his father left, Brian Griffin, who was still a robot dog then, taught Lelouch, whom Brian's son Vinny nicknamed "Lulu" and still does, how to keep his Geass under control, even though Brian has never used Geass, but has heard of it.

Season Six/Burnout
Sometime between the Gallaxhar/Megamind duel and the final battle with Aku, Lelouch, who has returned to Earth, and his Japanese friend, Suzaku Kururugi, both aged seventeen, have donned their respective identities of Zero and Lancelot, and have been asked by the Doctor (Doctor Who, that is) to borrow the Tardis and recruit all Torrentuff Animal teams of time to fight off an evil clone and save the world.
