If the Civil War had taken place in the DCU I can see Bats and Supes on opposing sides. Batman would probably take the role of Captain America and Superman the spot of Iron Man. Somehow things would factor out to being Lex Luthors fault but not until it was too late and Supes had killed Batman. Probably going on some crazy head trip and rippin' him in half. It would turn into one of those stories where everyone gets they morals and loyalties tested. As for who would be on who's side...that's tough but I'll try a few.
