Pietro Maximoff is the son of the genetic terrorist known as Magneto, and brother to the hex-casting Scarlet Witch.

Magneto and Professor Charles Xavier had discovered the Savage Land, a forgotten jungle. In this lost tropical world, the two men built a refuge for mutants seeking respite from persecution. But as time passed, their conflicting beliefs became a point of contention. Magneto felt that Homo superior represented the next step in human evolution, and that Homo sapiens should live under mutant rule. Xavier did not share his view. The tension grew, leading Magneto to expel Xavier -- with deadly force -- from the mutant haven they had created. Somehow, the Professor escaped with his life.

Eager to prove himself to Magneto since he was a child, Pietro offered to finish the job on at least one occasion. But when Magneto attacked Washington, D.C., with a fleet of reprogrammed Sentinel robots, it was Pietro who surreptitiously removed his father's thought-proof helmet -- enabling the telepathic Xavier to transform his one-time friend into a living super-magnet. Apparently, Quicksilver had grown tired of Magneto's constant criticism, ridicule and resentment.

Known Superhuman Powers: Quicksilver is a mutant who can think and move at extreme speeds. His entire body has adapted to the rigors of high-speed running, and his cardiovascular and respiratory systems are many times more efficient than those of a normal human being.
