I dunno - Batman has had a hell of a lot of lame-o villains, 'tis true, but most of them have a tendency to stick around for a little while. I mean, there are characters like the Polka-Dot Man and the Condiment King who are members (though seldom seen ones) in good standing of his rogues gallery. Does Wondy still have the Crimson Centipede and the Blue Snowman? I don't think so.
