Boom! Studios. They have their own superheroes and villains Irredeemable is about a superman type of hero who goes crazy from stress and starts killing millions of people. Incorruptible is from the same universe as irredeemable but from the perspective of a super villain who turns good because he wants to save the world from the superman type guy. Deathmatch is a comic where a bunch of super heroes and villains are put in a prison and are forced to fight each other to death. Their minds are wiped and don't know why they have to fight each other until they get put in an arena then they " remember" why they have to kill each other. The heroes and villains are all kinda like marvel and dc characters
