SET UP:A few months back (a few years in reality), Charles Xavier Shut-down Magnetos mind. What he didn't know was that all those evil thoughts had to go somewhere...
After a series of failures (Logans regression, Sabretooths rampage, etc) coupled with all of his negative emotions that he's locked away over the years, his subconcious finaly decided to go nuts...
A series of mysterious encounters with some powerful entity were linked together by only one clue: The word ONSLAUGHT. Juggernaught was punched and flew from canada to New Jersey. A Sentinal proccessing plant was completly made inactive. And Charles starts acting a little strange...
Then, Cyclops, Wolverine, Storm and Iceman are abducted and get beat like rag dolls. They think Onsluaght is responsible, but it was mearly one of his lackies, Post. This makes us wonder just HOW powerful this "Onslaught" guy is...
One day, while Jean is shopping, Onslught takes her on a tour of Xaviers truly twisted mind, and asks her to join him so he can use her mind to abstract the template of the Pheonix power. Despite the fact that everything she knows about Xavier has turned out to be a lie, she refuses. (A nice little continuity note: WAAAAAy back in X-Men #2 [1963 or so], Xavier admited to the readers he was in love with Jean, a fact which re-surfaces here and is exposed to jean for the first time. That pervert.)
The Juggernaught, knowing who Onslaught is but can't remember to due to a psionic block, seeks out Pheonix's assistance. Meanwhile, Xavier is upstairs watching a news report dealing with the beating of Denis Hogan, a mutant, along with viewing a pamphlet on Graydon Creeds bid for presidential election, and starts to snap, as a strange energy begins to engulf him...
Key Players: Proffesor X, Dark Beast, The X-Men, X-Man, The Avengers, Fantastic Four, Franklin Richards, Dr. Doom, Cable, the Sentinals, Apocalypse, and of course, Onslaught.
NOTES: We finaly get to find out who the X-traitor was, and the Z'Noxx chamber is finaly re-used (The Chamber is a filter that allows those inside it to use thier psionic powers, but those outside of it cannot detect them psionicly).
SYNOPSIS: While the X-Men are trying to find Juggernaught, he's really with Jean in the Z'noxx chamber, so they can find out who this bastich is. jean finds out, but doesn't tell Juggy, and tells him to run, because Onslaught is IN THE MANSION! Juggs runs into Xaviers study, only to find it trashed. Onslaught appears, and removes the source of Juggernaughts power, the Crimson Gem of Krytoakk, and reveiling that he's waited for this his entire life, he reviels himself to be Proffesor X, and then summons the X-Men.
The X-Men run to him, finding Charles sitting in a chair. he starts talking funny, and reveils himself to be Onslaught. In the ensuing battles, the mansion gets wrecked, and the X-men are almost killed (thaks to Bishop, they survived). Onslaught reveils to Bishop that he saw the Age of Apocalypse in his mind and will use Apocalypses plan in that reality to concure this one. D'OH! He leaves with Dark Beast in tow (Who'd kidnapped the real Beast and replaced him).
Meanwhile, Nate Grey (a.k.a. X-man) from the aformentioned reality tries to warn the Avengers about xavier turning into Onslaught. They head to The X-Mens mansion and are attacked by the X-Men, thinking the Avengers might be under Onslaughts sway. Battered and torn anyway, the X-men call a truce. The Avengers are sent to find Magneto, thinking this may be his doing (Onsluaght looks surprisingly like him), While the X-Men prepare for battle. The Avengers find "Joseph" instead, with Rouge in tow. The X-Men try to warn the Fantastic Four, who already know because Onslaught captured thier reality-altering son, Frankin. The three teams re-group at Four Freedoms plaza, along with all the other heroes they could find. However, Onslaught has sent his mercs into the streets (Dark Beast, Havok, fatal, post, and Holocaust), and re-programed the sentinals to do his bidding. The Super-folks do thier best to help, even with the assistance of Dr. Doom and Apocalypse (who have thier reasons), but to little avail.
Cyclops and Thor manage to go toe-to toe with Onslaught, and the free Xavier from his grasp. However, by this time, he already has X-Man and no longer needs the power-less Xavier, who was the only thing holding Onslaught back in the first place. CRAP...
The heroes realize they need protection against psionic attacks, So Iron Man, Reed Richards, Hank Pym and Dr. Doom construct psionic dampeners, while Pheonix and Cable back up the X-Men. However, Xavier, being the idealistic idiot that he is, goes of on his own to convince Onslaught that subjugating humanity is not right. however, Onslaught, discusted at what happened durring the Age of Apocalypse (they all got blowed up), decides he'll just destroy the planet instead. He summons a second Sun, and starrs siphoning energy. Mutant attacks become useless against him, beacuse he can now absorb thier power. So the Hulk goes in and pounds away, and when the smoke clears, the hulk AND his alter-ego Bruce Banner are laying there, with no sign of Onslaught. Turns ou he's been mutating the whole time, and is now just a collection of pure psionic energy. With Josephs and Cables help, Xavier is able to reach in and tries to telepathicly "fish out" Franklin and X-Man. As for Onslaught, the Avengers and other non-mutant heroes leap into him and absorb the energy, giving the X-men a tangible target they can safly beat on. However, as the world watches, all they see it the X-men killing off the Avengers and Fantastic Four. In the resulting explosion, Franklin and X-Man are freed, and Onslaught is destroyed.
THE DAY AFTER: The X-men are nationaly accused of killing the Avengers and Fantastic Four, and Xavier remands himself into the custody of the government.
RAMIFICATIONS: Franklin displays awesome powers by creating a "pocket universe" where the Heroes are sent, making way for the whole "Heroes Reborn" and "Heroes Return" storylines. Operation: Zero Tolerance is given permission to exterminate mutants by the national government. And the mansion needs repairs, again. And recently, it was revealed that Shadow King was freed, and was able to set up his plan for world-wide chaos!
