1. S'ym
S'ym is a demonic brute from the dimension Limbo, and has been an occasional enemy for the X-Men. He boasts enormous physical strength, even more so than Colossus, and has the distinction of having been able to break one of Wolverine's claws. S'ym can be defeated by few comic book weapons we've seen so far, and after he was infected with a techno-organic virus, he gained the ability to regenerate and heal himself, even if it seems that he's been defeated. He can also feed off of other life-forms and even turn them into similar versions of himself, basically making him a villain just too powerful to insert into an X-Men movie. If he can even make Wolverine look like a chump, then there's probably no place for him in Hollywood. Which of these insane comic book villains would you like to see in a movie?
