When an explosive event shatters the lives of the X-Men and takes away their mentor, the beaten heroes walk away from it all. Wolverine, the most legendary of all X-Men, reunites them to prevent the world's destruction. Forge has managed to break the code of the Sentinel data they stole from the Trask Lab, and reports that Master Mold is a computer that operates all of the city's Sentinels and appears to be same Master Mold Xavier is battling in the future. The timing could not be worse. Senator Kelly has been given the green light for Project Wideawake, his mutant registration programme that is actively using the Sentinels. The X-Men find Master Mold's location from the data and head out to stop the future war by destroying it. But the location is a set-up from Master Mold itself and they walk right into a warehouse full of activated Sentinels! The team is not faring well against their intelligent enemies who are sharing their data back to the real Master Mold to modify their fighting techniques. Surprisingly, the Brotherhood shows up to save the X-Men from the devastating Sentinels. Quicksilver has been shunned by Magneto for the last time and he will be damned if he is going to watch the X-Men, the bane of his father's existence, be defeated in one battle. Together, the Brotherhood and the X-Men shut down all the Sentinels and the Master Mold, or so they think. When Wolverine reports back to Xavier in the future, nothing has changed. The Master Mold must have survived somehow.
