X-Men: First Class

In 1944, at the Auschwitz concentration camp, Nazi officer Klaus Schmidt witnesses young prisoner Erik Lehnsherr bend a metal gate with his mind upon being separated from his mother. In his office, Schmidt orders Erik to move a coin on his desk, and kills his mother when Erik couldn't. In grief and anger, Erik's magnetic power manifests, killing two guards and destroying the room. Separately, at a mansion in Westchester County, New York, child telepath Charles Xavier meets young shapeshifter Raven, whose natural form is blue-skinned and scaly. Overjoyed to meet someone "different", like himself, he invites her to live with his family as his foster sister.
