I'm a bit of a Superman-ologist. Sure, he was once murdered by one of his greatest nemeses, but he would defeat Batman no contest. Yeah, I read Superman/Batman: Public Enemies and Batman had a kryptonite outfit at one point, but Supes had laser vision and arctic breath--two things that can hault Batman in a heartbeat, with or without kryptonite. Kryptonite batarangs? Pish posh--Supes was stabbed with a krypto-knife and had it broken-off in his back and LIVED, although was dead for a brief period of time, for god's sake! If Superman can handle criminal mastermind Lex Luthor and nemesis Brainiac, then Batman is no problemo.
