Claremont and Byrne's iconic X-MEN run continues as the team faces the reality-warping mutant menace Proteus! But first, we begin with Magneto. He has a score to settle with the X-Men, who must struggle to hold on to their humanity as their nemesis strips them to their cores. A narrow escape leads them out of the fire, into the frying pan (A.K.A. the Savage Land) where they face Sauron and the immortal Garokk, the Petrified Man. Meanwhile, thinking her teammates killed in their battle with Magneto, Jean Grey heads for Muir Island. That's not all, though: The greatest super-team from up north - Alpha Flight - makes its debut; Arcade toys with our heroes; and the first pieces of Wolverine's origin are revealed! Collecting: X-Men (1963) 111-128 & Annual (1970) 3, Marvel Team-Up (1972) 89 and Incredible Hulk Annual (1968) 7
