Onslaught

Onslaught is a fictional character appearing in American comic books published by Marvel Comics. Onslaught was written as a sentient psionic entity created from the consciousness of two mutants: Professor Charles Xavier and Magneto. During a battle between the X-Men and Magneto's Acolytes, Professor Xavier used his telepathic powers to shut down Magneto's mind, rendering him catatonic. It was explained through the Onslaught crossover series that the darkest aspect of Magneto's mind escaped into Xavier's subconscious, where it "merged" with Xavier's own darker nature to eventually grow into a separate persona of its own. Publication history The character first appeared in cameo in X-Men: Prime #1 (July 1995), named in Uncanny X-Men #322 and made his first full appearance in X-Men vol. 2, #53 (June 1996) where he was co-created by writers Scott Lobdell, Mark Waid, and artist Andy Kubert. He was written and introduced as a villain that was part of the effect of events in the 1993 "Fatal Attractions" storyline.
