11. JEAN GREYWhen Jean Grey isn’t destroying planets, or being temporarily "dead" as the Phoenix, she’s actually pretty hot. That long red hair and tight spandex suit (Professor X, you dirty old pacifist) has been one of the most memorable parts of the X-Men universe for decades.
But one word of warning that all heroes should heed: Don’t think about her naked while standing in front of her (unless you're absolutely sure she's feeling you). She is a mind reader after all.
