Booster Gold
From Superdickery
Booster Gold is a superhero known for many things, such as being a crook, having his own episode of Justice League Unlimited, being a damn good football player, getting his ass beaten by Doomsday, being a JLI member, having really stupid armor in the 90's, being Supernova, having an exquisite rear end, time travel, and being one of the sexiest men in the entire DCU, to hear HotAndCold tell it.
Booster Gold's real name is Michael Jon Carter. His twin sister is named Michelle Carter. It is currently unknown what on Earth their parents (or their creator, Dan Jurgens), were thinking.
He's also a sockpuppet, easily found in this thread, although he has been known to show up in other places semi-frequently.
