The X-Men #82

From the subterranean shadows of 1973, this issue of The X-Men presents a striking showdown as the villainous Tyrannus commands a massive, looming robot — energy blazing from its chest — while blue-and-yellow-clad X-Men scramble to face the threat below. Dan Adkins's cover work captures the scale of the danger brilliantly, with Tyrannus himself brandishing a sword in the upper left and declaring victory already his. Titled "War-- In a World of Darkness!," this twenty-cent Marvel gem promises a tense underground battle that fans of the era's superhero adventure won't want to miss.
