Since Dc is so fascinated with the concept on an "evil" Superman, I decided to keep track on them just for fun :-P
- Injustice Superman: Pretty much a morally ambigious turned dictator and evil, Superman.
- Brutall: A brainwashed version of Supes.
- SuperDoom: An alternate universe Supes.
- Lord Superman: Like SuperDoom, currently in JLBeyond comic.
- Ultraman: Same with SuperDoom and Lord Superman.
- Superman Future's End: Pawn of an evil force.
- And Superman with Doomsday virus which basically turns him into Doomsday
And that is only in one year's worth of time :-P
