15 Greatest Marvel Comic Book Villains Of All Time

3. Magneto

Magneto may be a hero of sorts these days as he fights alongside the X-Men he once tried to destroy, but that doesn't wipe away the fact that the Master of Magnetism spent decades on the dark side with his Brotherhood of Evil Mutants.

Responsible for almost countless deaths, Magneto has also torn the Adamantium from Wolverine's skeleton and put Charles Xavier in that wheelchair, all while lashing out at the humans he so despises for the crimes they've committed against his people. While he may have earned forgiveness for those acts, you just know that a return to his evil ways is inevitable for Magneto somewhere down the line.
