History

Onslaught was a psionic entity created from the conciousness of both Xavier and Magneto. During a battle Xavier used his telepathic ability to enter and shut down Magneto's mind, leaving the latter in a catatonic state. While Xavier was in Magneto's mind, Magneto's hate and anger entered Xavier's mind and combined with all of the negative feelings from the past 30 years that Xavier had suppressed. This combination created Onslaught.

Onslaught remained dormant for some time. Gradually, Xavier's frustration with his dream of mutant-human harmony began to rise, increased by the daily growth of anti-mutant hysteria, the deaths of dozens of mutants from the lethal Legacy Virus, and his own failed attempt to rehabilitate the mutant sociopath called Sabretooth. Xavier reached his breaking point when anti-mutant humans killed a young mutant near the grounds of the Xavier Institute for Higher Learning, the secret base of the X-Men. It was at this point that Onslaught awakened within Xavier and began to manifest himself to others.

Following an encounter with the criminal called Juggernaut, Onslaught invaded a government sanctioned Sentinel base. He downloaded the current specifications for the mutant-hunting androids and erased portions of the memories of the employees working in the factory. Soon after, while hiding in Xavier's mind, Onslaught encountered the telepathic, telekinetic X-Man. X-Man pulled the Professor's body from the astral plane, a feat never before achieved. Through X-Man's actions, Onslaught was able to escape Xavier's mind and move independently. After taking full possession of the Professor's mind and body, Onslaught-as-Xavier called together the X-Men. When they resisted his plan to turn them into soldiers fighting a total war against humans, Onslaught revealed himself to the X-Men and attempted to destroy the outlaw adventurers. The time travelling mutant soldier called Bishop, remembering childhood stories of a traitor betraying and killing the X-Men, began to realize that the guilty party was Onslaught-as-Xavier. Bishop rescued his teammates. Taking Xavier's body with him, Onslaught escaped.

Once free, Onslaught created a childlike psionic projection named Charles to gain the trust of young Franklin Richards, a mutant possessing the latent power to alter reality. Onslaught succeeded in capturing the child despite a rescue attempt by Franklin's parents, Mister Fantastic and Invisible Woman, members of the team known as the Fantastic Four. Now carrying Franklin and Xavier, Onslaught captured X-Man, intending to use his raw psionic power to fuel Onslaught�s plans to transform the human race into a collective consciousness. Onslaught returned to New York, reprogramming the Sentinel robots to obey his commands and form a protective circle around Manhattan, sealing off the island from the rest of the world.

The X-Men, the Fantastic Four and the Avengers, challenged Onslaught. Their first confrontation with the entity and his minions resulted in the rescue of a now-powerless Xavier, who retained his usual benevolent personality. Onslaught now existed as psionic energy contained within his armor. A second and final confrontation occurred at his Central Park citadel. After a number of attempts to free Franklin and X-Man from Onslaught's seemingly impervious armor, the heroes regrouped. During their next assault, Jean Grey used her telepathy to turn off the part of the Hulk's mind that contained the rationality of his alter ego, Dr. Bruce Banner. The now savage Hulk, possessed of a nearly animalistic intelligence and unbelievable strength, battled Onslaught and tore apart his armor. The resulting explosion of psionic energy separated Banner and the Hulk, and Onslaught was left as an energy being, immune to most physical harm. Onslaught then used Franklin's powers to create a second sun that would destroy the heroes and Manhattan.

The Avenger known as Thor, God of Thunder, flew into the energy being, disrupting Onslaught's form. Realizing that Thor's efforts alone were insufficient to destroy Onslaught, the non-mutant members of the Avengers and the Fantastic Four entered the energy field. The X-Men were unable to do this, as it was theorized that if Onslaught, a being of mutant origin, came to possess a mutant host, he would become unstoppable. Onslaught dissolved, seemingly destroyed, along with those who had thrown themselves into the his body. The remaining Sentinels were disabled, Franklin and X-Man were rescued, and Manhattan was returned to normal. Later, it was revealed that the Avengers and the Fantastic Four did not die, as had been assumed. Rather, they were reborn in a pocket universe created by Franklin. The Avengers and the Fantastic Four returned to their home months later, possessing only hazy memories of their time on Counter-Earth.
