I always liked the Amazing Spider Man in the comic books, but this damn Spider Man movie franchise has turned him into an idiot. Tobey Maguire
I think I'll have to defer to my second and third favorite comic book heroes. #2 on the list is Gambit. He gets overlooked because his powers aren't that flashy, but the dude can lay out some damage. (As we'll hopefully see in the upcoming Wolverine film) Also, the comic book character of Gambit was HILARIOUS.
#3 on my favorites list, and also one of the most powerful superheroes ever is Rogue. Now, before you bash because the movies have turned her into a complete idiot- realize what Rogue really is in the comic book sense. Whatever she touches she drains the powers out of. She drained the power of flight, superhuman strength, and can drain other powers and memories as well. The only reason she hasn't become incredibly strong in all aspects is because she does not like to use her drain power and the personalities she absorbs cause her to go insane. She limits herself, but even doing so she became intensely powerful. There was a point during her life that she was incredibly powerful. When she had the abilities of Ms. Marvel, Sunfire, and several other mutants. She was basically like Superman at that time.
