Me, I'd be either Psylocke (nothing like a telepathic ninja) or Mystique. The movie Mystique that is, being that the comic Mystique was pretty wussy and useless in comparison--and not nearly as sexy! Nightcrawler is a close second, except for the fact that whenever he teleports he leaves behind the potent odor of brimstone... I imagine that has quite an effect on the social life.

If you were a superhero, who would you be? What mutant powers would you choose? DC or Marvel?
