Onslaught was a sentient psionic entity created from the consciousness of Professor Charles Xavier and Magneto. During a battle between the X-Men and Magneto's Acolytes, Magneto used his powers to rip the adamantium from Wolverine's skeleton, causing such extensive injuries that his healing factor burned itself out. Xavier was so unhinged with anger over the brutality of Magneto's assault against Wolverine that he used his telepathic powers to shut down Magneto's mind, rendering him catatonic. During the psionic contact, Magneto's anger, grief and lust for vengeance entered Xavier's consciousness; commingling with every long-suppressed negative feeling Xavier had endured during the last 30 years. This aggregation resulted in the being known as Onslaught.
