A largely unknown fact about his life, Charles Xavier was called into action by the US government after Sebastian Shaw, a nazi scientist and mutant supremacist, engineered a stand-off between amassed United States and Soviet naval forces. Xavier telepathically searched the fleets in an attempt to locate Shaw, but was unable to do so due to Shaw possessing a helmet that blocked telepathic contact.

The X-Men officially come into the public eye after flying there and stopping the SENTINEL attack.

July 1996 - "Mutant Cure" Found
Developed by Worthington Labs, the Mutant Cure was a pharmaceutical designed to suppress the X-Gene by chemically lobotomizing a section of a subject’s brain. Deemed inhumane by some, it sparked great controversy around the world almost immediately.

In response, Magneto rallied mutants around the world, comparing the cure to the Holocaust. Calling themselves the Brotherhood of Mutants, many groups around the world either started violent protests, or tried to directly find and destroy the cure and its’ manufacturers.

SENTINELs were deployed once again, and the X-Men fought Magneto and the Brotherhood directly in Manhattan, New York, several blocks away from Worthington Tower. Magneto retreats, disappearing.

June 2012 - The Mutant Massacre/Uprising
The US Government declares war on the foreign nation of Genosha, citing terrorist incidents that they had pinned on the young nation. With little warning, the country was faced by an invasion of SENTINELs. During the battle, many mutants perished, including Wanda Maximoff and Magneto.

The following days, mutants around the globe began retaliating, with violent protests turning into direct attacks on respective country governments officials and politicians. Soon, mutants began dragging politicians, cops, and soldiers out of their homes, threatening to kill them unless the man responsible for the Genosha attack commits suicide on live TV.

The X-Men did their best to protect people, but were unable to get to all of them. Scott Summers also returns to the X-Men during this attack, and almost dies during a battle with a fire-breathing mutant in Kansas.

Left without any other solution, Charles Xavier uses Cerebro and all of his telepathic might to temporarily pacify every mutant mind on Earth. He is successful and the attacks stop long enough for the authorities to get the situation back under control, however his mind and body are left permanently damaged.

Following the mass mutant uprising the SENTINEL program gains even more support.

The artificial island nation was left unsuitable for long-term habitation due to the heavy ordnance used to subdue Magneto. Expeditions to the island since have reported strange incidents. Theories point to Wanda Maximoff’s reality-bending powers causing a rift in reality upon her violent death.
