Amazing Adventures #14

In "The Uncanny Threat of... Unus the Untouchable!", Beast's departure from the X-Men takes a surprising turn when he becomes a wrestler—only to cross paths with Unus, a mutant whose powers make him untouchable. Written by Stan Lee and illustrated by Jack Kirby, with Chic Stone handling inks and Sam Rosen on letters, this 1981 Marvel classic sees the X-Men confront Unus in a battle that spirals into a strange twist involving a machine designed to amplify his abilities. The cover, by Jack Kirby and Chic Stone, captures the moment of tension as the mutant threat looms large.
