Seen In: Onslaught: Marvel Universe #1 Oh Onslaught, one of the best examples of the excess of 90s comics. A long, drawn-out storyline that began in the X-Men titles and soon grew to swallow up the entire Marvel Universe, it was a sad omen of what would become an almost annual tradition at Marvel of line-wide crossovers that would proclaim "nothing will EVER be the same again," only for the status quo to be restored a few years later. Onslaught was created when Professor X mind-wiped Magneto and somehow absorbed some of his essence (don't ask), and then later, Onslaught became its own entity and gave itself its own body. Kidnapping both Franklin Richards and Nate Grey and usurping their immense powers for himself, Onslaught plotted to destroy both humans and mutants. With a Sentinel army occupying New York, Onslaught created a citadel in Central Park and the combined forces of the Avengers, the Fantastic Four, and the X-Men converged on him for a final battle. After the Hulk sacrificed himself to destroy Onslaught's armor, somehow Onslaught still survived as a being of pure psionic energy. The only way to stop him was for the non-mutant heroes to run into the energy field, somehow sucking up that energy and then giving the rest of the X-Men something to hit, which they then blasted with all their power until Onslaught and the heroes just disappeared (although in reality, they were transferred into a pocket universe created by Franklin Richards€”again, don't ask). This type of solution for defeating an all-powerful villain is so awful, it sounds like something a kid would come up with when playing with his action figures. But Onslaught was mercifully gone. Until ten years later, when someone bizarrely thought it would be a good idea for Jeph Loeb and Rob Liefeld to come up with Onslaught Reborn.
