He does it a lot XD He was Lelouchx (something before that too) then like... CatLover then like JetBlack then JetBlack_ then JetBlack__ 或者 something like that
Concerning his evolution on Fanpop, it goes like this: Servamp -> Lelouchx -> CatsLover8 -> SeraphOfTheEnd8 -> Heartbeat -> JetBlack and variations !!!!
