Cat in the Hat vs The Mask
Movie versions. Who would win in a fight?
Both have toon-like reality warping abilities, shapeshifting, and regen - Mask can eat a bomb while the Cat in the Hat can chop off his tail and whatnot and both be fine in the next scene. Cat in the Hat can also teleport and pop up out of nowhere, duplicate himself, warp his environment into a game show/infomercial, and pull random wacky devices out of his bag (not to mention Thing 1 and Thing 2), whereas Mask can transform body parts into anything, and pull limitless weapons out of his coat.
So who wins in a battle to the death (if either can be killed)???
