The X-Men #32

From May 1967, this Marvel Comics Group issue delivers one of the most visually arresting covers of the Silver Age X-Men run. The Juggernaut dominates the center in his crimson armor, having scattered the entire original X-Men team — Marvel Girl, Iceman, Angel, Cyclops, and Beast — across a rocky battlefield, while a strained Professor X looks on from above, hands pressed to his temples in concentration. Cover pencils by Werner Roth and inks by John Tartaglione capture the sheer, overwhelming force of the villain with real dramatic weight, making "Beware the Juggernaut, My Son!" a compelling snapshot of the X-Men at their most outmatched.
