I guess Spider-Man is a gentle man, so he'll never fight with a so nice woman such as Catwoman.
Very sad but I cannot write answer less than 140 characters long.
I think Spiderman would win because he has web powers and she has nothing. Unless she uses her whip then it would most likely be even. so yeah I guess that's all. Really I have to have at least have 140 characters! This sucks! There!
