8. Magneto- 500 million estimated
He is not only the master of all metal, Magneto made his fortune by stealing the Nazi gold from Hydra. Pretty bad-ass for a superhero, right?
Well, he is not really a superhero; he used to be one when he and Xavier were friends. But not anymore since all he wants is to tell everyone about the mutants.
Magneto can control all the metals; create magnetic shields and fly, all with the help of his superpowers.
He is one of the most powerful mutants on Earth and one of the richest superheroes in the world.
