Storm

Storm was one of the most popular character in X-Men history, but she was severely underplayed in the movies, although X-Men: Apocalypse tried to do her justice. Storm is able to manipulate the weather with varying effects (some of them terrifying and not restricted to Earth), but her character is richer than that.

With many sorcerers and sorceresses as ancestors, Storm’s magical potential is enormous, though she has yet to explore it. But, thanks to her ancestry, Storm was once able to host the avatar of Eternity itself.

Storm is a skilled thief and combatant, but her body has also developed the ability to control the weather. She’s able to resist extremes of temperature and atmospheric pressure, her night vision is excellent, and she is highly resilient.

Oddly, she isn’t an Omega-level mutant, but if she could realize her true potential, we are more than certain that she’d be among the most powerful on this list.
