my favorite villian would have to be venom
Venom is a great choice as a villain, he made Spiderman his little B****, you have to see it to know what I mean (hopefully he will be in Spiderman 3). However my choice as villain would be Apocalypse from X-Men (I want him in X-men 3), not because he' s an unstoppable monster (which he is, he could f' k Venom up with ease) but because he' s the only villain with the exact twisted sick sense of humor that I like. You know how its a cliche for some villains and super heroes to have some weakness(especially the really powerful ones, think Super Man with Kryptonite). Anyways Apocalypse went out of his way to create documents thousands of years ago (he was around since the dawn of time) of a fake weakness of his, he even had pictures illustrating that there was a spot at the back of his neck that if struck with enough force would kill him. Once one of his mortal enemies (the Angel guy with the metal wings) found this info he coordinated an attack with other mutants to take advantage of this supposed weakness. The look on Angels face was priceless when he found out the weakness didn' t work.
As for favorite Hero I' m torn between Batman, Spawn and Marv from Sin Cities (if you can consider him a Hero).
