Magneto is a mutant, leader and founder of the Brotherhood of Mutants. He has the ability to manipulate create magnetic fields and control metal telekinetically. Magneto is one of the most infamous mutants, having a stand against humans due to him being a part of the Holocaust and how humans are known to hate and fear mutants. Similarly to Professor X, Magneto has a strong belief and formed a team of his own, the Brotherhood of Mutants, after he was a founding member of the X-Men with Professor X, having been good friends. Unlike Professor X, Magneto's team's belief and goal isn't to equally live with humans, but to rise above and rule them.
