Storm has been in control of her omega-level abilities and knew her worth from a young age. That’s why she’s been one of the greatest X-Men since day one. It doesn’t matter if you call her mutant, goddess, queen, or Regent of Mars, the one thing you won’t do is disrespect her.
A lot of her enemies have found out what happens when you do. It usually ends with them being hit with lightning, thrown via a gust of wind, or something incredibly nasty if you really make her mad. The funny thing is she doesn’t need her mutant abilities to be powerful. She proved that to Cyclops when she beat him for leadership of the X-Men without her mutant powers (read Uncanny X-Men for more on that).

8. Charles Xavier
Charles Xavier is the premier telepath in the world. Maybe in the entire universe. He’s so powerful that he’s stopped people controlled by the Phoenix Force. That in itself is enough to put him on this list. The Phoenix has destroyed entire planets without being stopped. However, that’s not what put him in the top ten. Xavier’s ability to trick the world is what did it. Charles Xavier made the world believe he was an honorable man. His intentions may have been good, but he went about it the wrong way.
He erased Wolverine’s memory because he needed a weapon and Cyclops’ memory of having a brother to keep Scott on the team. Two X-Men who loved him like a father. The worst may have been when he enslaved the danger room knowing it was sentient (Astonishing X-Men: Danger). If you thought the creation of Krakoa would stop him, you’d be wrong. He’s still a manipulative monster.
