Favorite Super Hero and Villain?

[DaZachAttack]

I am doing a survey for my Inquiry report. Your super hero and villain must be from a U.S. comic book (ex. V, Ironman) (V is the villain from V for Vendetta) Please include both the hero and the villain. The best answer will be whoever follows my directions and answer my question first. Thanks!
for the hero only: please choose btween superman, batman, ironman and hulk
