To the Left we have RULK, a Red Hulk who's intelligent and knows a thing or two about guns, hand-to-hand combat and kicking ass. Not much is known about the Jolly Red Giant's past (which is the way Jeph Loeb likes it) oh, did I mention he once beat both the original Hulk and the current Thor?
To the Right we have SUPERMAN PRIME, an alternate reality Clark Kent who came from a Universe in which superheroes were only comic book characters. He sorta went completely insane after The Anti-Monitor destroyed his Universe, killed his hot girlfriend Laurie and erased his Parents from existence. To make things worse he's still has the mentality of the same kid who left with the Silver Age Superman to go fight in the Crisis...however he has been twisted by countless years of pain, heart-ache, a couple of deaths, multiple ass-kickings and the fact that he will NEVER become the hero he so desperately wanted to become.
