X-Factor: the Original X-men Omnibus Vol. 1 Simonson First Issue Cover

When Jean Grey returns from a watery grave, the original X-Men reunite - as X-Factor! But for Marvel Girl, Cyclops, Beast, Angel and Iceman, posing as a mutant-hunting organization gets complicated fast! And things get worse when the ageless villain Apocalypse makes the scene! Then, when X-Factor is drawn into the chaos of the Mutant Massacre, Angel suffers a grievous injury and will be changed forever! As X-Factor rescues young mutants - including Leech, Boom-Boom and Rictor - the Beast undergoes a radical metamorphosis, Iceman battles alongside Thor, tragedy pushes Cyclops to the brink of insanity and a traitor stalks the team from within!
