It is a favorite pastime of comic book fans to construct fantasy battles between their favorite characters. Tallying up the pros/cons of talents and powers to see who will come out on top. This can lead to an endless argument of who will win, especially involving personally attached characters. Who wants to see their favorite hero or villain lose? The comic book companies have already made comics depicting some of these famous battles to help settle the dispute, if that is possible.
