X-Men, Vol. 3: First to Last

Think you know everything there is to know about the original X-Men? Think again! Something happened to Cyclops, Marvel Girl, Beast, Angel, Iceman and Professor X years ago, a secret so horrible that it has been locked away in the dark corner of Cyclops' mind until today. What crisis strikes in the present that calls upon memories of the past? Witness the astonishing debut of the Evolutionaries!

Who are the Evolutionaries and why doesn't anyone remember when they fought Xavier and his original five X-Men? Cyclops and his crew on Utopia better figure out quick or the Evolutionaries are going to wipe out every human on the planet. That's right, every HUMAN.
