Marvel Two-in-One #19

This September 1976 team-up pairs the rocky-skinned Thing with the fierce Tigra in "Claws of the Cougar!" — and the cover by Jack Kirby, John Romita, and Frank Giacoia makes the stakes immediately clear. Tigra lunges forward claws-first, demanding the return of the Thing's power while a menacing, bestial Cougar crouches nearby, boasting that no one can stand against him. It's a vivid, kinetic image that captures both the urgency of the duo's situation and the genuine threat posed by their feline-themed foe.
