Avengers vs. X-Men
2012The Phoenix Force returns to Earth, heading for Hope Summers. Captain America demands the X-Men hand her over for containment; Cyclops refuses, believing the Phoenix will restart the mutant race. War erupts between the two teams. When Iron Man attempts to destroy the Phoenix in orbit, he accidentally splits it among five X-Men — Cyclops, Emma Frost, Namor, Colossus, and Magik — who become the Phoenix Five and begin remaking the world into a utopia. But the Phoenix's power corrupts them one by one. Namor attacks Wakanda. Colossus and Magik turn on each other. Finally, a Dark Phoenix-possessed Cyclops kills Professor Xavier. Hope and the Scarlet Witch together channel the Phoenix Force to declare "No more Phoenix," dispersing it into new mutant activations worldwide — reversing Decimation. Cyclops is imprisoned. The Avengers form a unity squad. The mutant race is reborn, but at a devastating cost.
