The Greatest Marvel Villains of All Time

Onslaught

What do you get when you combine the collective consciousness of two powerful beings like Professor X and Magneto? You get Onslaught. Onslaught possessed all of the mutant abilities of his progenitors Professor X and Magneto. He later added the powers of Franklin Richards and Nate Grey to his, making him even more powerful. He was ultimately contained by the heroes only because of the Franklin’s intervention to spare their lives, which broke Onslaught’s control.
