In 1963, Stan Lee and Jack Kirby introduced their latest costumed creations to the burgeoning Marvel Universe. Cyclops, Beast, Iceman, Angel, Marvel Girl and their leader, the mysteriously named Professor X were the X-Men - and little did anyone know that they would take the industry by storm! Lee and Kirby billed them as "The Strangest Super-Heroes of All!" And while their mutant powers were certainly weird, the binding concept of this band of heroes - a group feared and hated for being different - was pure Marvel relevance. This Omnibus collects the X-Men's earliest adventures as they encounter Magneto, the Brotherhood of Evil Mutants, the Juggernaut, Ka-Zar of the Savage Land, the Sentinels and more of Marvel's greatest heroes and villains! Collecting X-MEN (1963) #1-31. Rated T+
