Disillusioned, Magneto immediately reverses the damage he had done to the Earth's magnetic poles. Despite insisting that Professor X would have forgiven him, Cyclops disintegrates Magneto's head with his optic blast at Magneto's request. The heroes destroy the citadel and leave. Eight days later, the world has begun to recover from the devastation. Cyclops gives a speech in Washington D.C. before a crowd of anti-mutant protesters. He acknowledges Magneto's crimes, but pleads for peace between humans and mutants. He also announces that Congress is currently voting on a bill that will require all mutants to turn themselves in to the U.S. government or be shot on sight.
