Onslaught is a psionic entity created from the consciousness of the mutants, Professor Charles Xavier and Magneto.
Though he was once part of those characters he manifested as a separate independent entity.

Onslaught possessed the combined abilities of Professor X, Magneto, Franklin Richards, and X-Man, including telepathy, telekinesis, astral projection, illusion creation, mental bolt projection, sensing mutant presences, manipulating magnetic fields, and affecting reality itself. Onslaught could also enhance its physical size and strength.
