Tales of Suspense #80

In "When Fall the Mighty!", the Sub-Mariner launches a furious assault on a vulnerable Iron Man in his lab, forcing the armored hero into a desperate gambit. Tricking his aquatic foe into sealing himself in a reinforced safe room, Iron Man buys time to recharge—just as Sub-Mariner, also drained, takes flight toward the ocean for a quick recovery. With police arriving to accuse Iron Man of destruction and Pepper and Happy on the scene, the clash is far from over. The Sub-Mariner, now refreshed, prepares for round two.

In "He Who Holds the Cosmic Cube," Captain America races to intercept a stolen weapon of unimaginable power—the Cosmic Cube—after uncovering a traitor in the skies above. With the help of a desperate pilot and the enigmatic Keeper, Cap is drawn into a deadly game of pursuit, only to face a revelation that ties the Cube’s fate to a long-buried tragedy. The Red Skull’s shadow looms large as Cap confronts a foe whose power now bends reality itself.
