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! Taking the lead for a few issues is famed X-Men writer CHRIS YOST (X-FORCE) and with all this danger, he''s lucky to have regular X-MEN artist PACO MEDINA and DALIBOR TALAJIC (PUNISHER) along for the ride.
