Essential X-Men Vol. 6

The word "mutant" means "change," and there was plenty of that when the Uncanny X-Men counted down to the Marvel Mutant Massacre - beginning with the trial of Magneto! Rachel Summers became Phoenix, and the Brotherhood became Freedom Force! Lady Deathstrike became a cyborg, Moonstar a Valkyrie, Colossus a killer and Psylocke an X-Man! And Sabretooth first set his clawed foot into the X-Universe alongside his fellow Marauders! Guest-starring the original X-Factor, Power Pack and Thor! Gods, Morlocks, talking frogs and more!
