Los Vengadores #101

In the midst of a sudden clash, the Sub-Mariner storms Iron Man’s lab, overwhelming him with fury. With quick thinking, Iron Man lures his foe into a reinforced safe room and seals him inside, buying time to recharge—just as the Sub-Mariner, needing his own recharge, takes flight toward the ocean. Back at Stark Industries, police arrive, blaming Iron Man for the damage, while Pepper and Happy show up in the chaos. As the Sub-Mariner returns, refreshed and ready for another fight, the tension mounts once more.

In "null," Captain America races to save a downed pilot—only to uncover a shocking betrayal when the man reveals himself as an A.I.M. agent. With the stolen Cosmic Cube en route to the Red Skull, Cap pursues the keeper across the skies, culminating in a desperate parachute descent onto a remote island where the Skull’s chilling truth awaits.
