Collects X-Men (1963) #122-131 & Uncanny X-Men Annual #3.
*Chris Claremont, Dave Cockrum and John Byrne took a little reprint series called X-MEN and turned it into the all-new, all-different titan that conquered comicdom. Experience the thrills and excitement of these classic tales as the X-Men battle the mutant menace Proteus, the trickster Arcade (with a little help from that web-slinging wonder, Spider-Man) and the White Queen! Witness the emergence of Jean Grey as the Phoenix; Colossus’ transformation into the Proletarian; and the first appearances of Emma Frost, the Hellfire Club, disco-queen Dazzler and Kitty Pryde! Featuring an introduction by the X-Father himself, Chris Claremont and an awesome annual with art by George Pérez! *Source: marvel.com
