Plot

Captain America (as Steve Rogers) gets a job as a boxer. Meanwhile, Kang the Conqueror plans to attack the Avengers yet again. Adding a fourth floor to the Avengers HQ, he lures the Avengers into an unescapable room and transports them to the future. Kang tries to show his power to the future Princess Ravonna but she doesn't care. Steve Rogers gets worried hearing about the Avengers disappearance. The Avengers then attempt to make an escape, but Scarlet Witch and Hawkeye are recaptured leaving Quicksilver on his own. Captain America then appears, sending himself to the future using the Recreater. There, he meets up with Quicksilver with help from Princess Ravonna. They confront Kang, and are joined by Hawkeye and Scarlet Witch, who re-escaped. Ravonna still denies Kang marriage, so his armies move in to destroy the city.
