History
His metamutant powers manifested in his teens, making his brother Will Magnus hate and fear him.
Assuming the identity of Magneto, Erik formed a team of fellow super-powered metamutants know as The Brotherhood of Mutants.
The rivalry between the Magnus brothers reached a fatal crossroads when Will's Sentinel robots murdered the members of the Brotherhood, except Magneto.
In their memory, Erik used hid awesome magnetic might to create the Uncanny Magnetic Men (a band of robots designed to fight for the metamutant cause and against the Sentinels).
Magneto created the super-computer known as Cerebro in order to locate metamutants and help them. A strong rivalry exists between Magneto and Mister X (leader of the JLX).
