Lies and slander! A charming smile as his is due for much better than Toad.

I'm half tempted to say Cyclops or Ice-Man. Because let's face it, he couldn't really go for any other part. He couldn't do Wolverine, or Nightstalker or Charles or Magneto. Can't be any of the chick mutants, so that really only leaves those two.

He could be the fire guy who manipulates flames, but he seems a bit too old for that.

I'm going to say Ice-man.
