Batman is a human who puts on a cape and tights and thinks he’s a hero. This doesn’t make him a hero. Instead it makes him a guy who ends up relying on gadgets and kung fu. Mario has super saiyan mode and paper form. He also has over 30 other super forms. Nearly all of them can beat Batman. Maybe Batman’s too old. Mario wins.

Update! Mario doesn’t have super saiyan mode anymore. Also, Batman’s definitely proven himself as a hero now and his hand to hand combat abilities are topnotch. He’s also got his GL Power Ring and super speed. Mario wouldn’t be able to take him down in this round. Batman wins.
