History: Charles Xavier's telepathic powers began emerging during adolescence; he learned to control them as he grew older. As an adult, Xavier befriended the mutant known as Magneto. Together, they discovered the Savage Land, a forgotten jungle. In this lost tropical world, Xavier and Magneto built a refuge for mutants seeking respite from persecution. For a time, the two men found the peace they sought -- but the partnership began to dissolve as Magneto became increasingly hateful toward mankind. He came to believe Homo superior represented the next step in human evolution, and that Homo sapiens should live under the rule of mutants.
Xavier did not share Magneto's view. The two fought, with Magneto claiming their tropical haven. He ended the struggle by paralyzing Xavier with a metal spear through the back. Xavier managed to escape and returned to the United States, where he established his Institute for Gifted Children -- using his ancestral mansion as a secret base to train young mutants to use their powers for humanity's benefit.

He can induce illusions, temporary mental or physical paralysis, loss of specific memories, or total amnesia; project mind-numbing mental bolts; and sense the presence of mutants within a small radius. Other abilities include telekinesis and astral projection.

Weapons: Professor X designed and constructed the Cerebro system -- a room-sized super-computer capable of detecting mutants over vast areas.
