During a chaotic clash with a desperate, heavy-artillery Hydra cell, the Avengers find themselves pinned down by experimental alien-tech weaponry. Just as the tide begins to turn against Earth's Mightiest Heroes, a mysterious armored newcomer designated as Apex drops from the sky. Utilizing advanced quantum weaponry, unstoppable boot jets, and an indestructible Imprevium-12 chassis, the stranger neutralizes the entire Hydra army in a matter of minutes. Left standing in the smoking craters, the stunned Avengers are desperate to recruit this powerhouse—but they have absolutely no idea who is behind the mask.
