Lex Luthor’s a very smart person, but more importantly, he’s Superman’s (chuckle) greatest enemy. He’s taken down Superman more times than anyone dares count. The Joker is tough and always a thorn in Batman’s side, but is just not as impressive. Lex Luthor got the powers of Superman and used them to pwn. The Joker takes yet another loss with this match, but he’ll be back. One of these days he’ll be back. You can count on it. Lex Luthor wins.
