As bystanders gawk at explosions issuing from within Avengers Mansion, inside battle rages between the Avengers and Ultron-6. In another part of the mansion the Vision agonizes over his role in Ultron’s resurrection, realizing that Ultron must have programmed him to resurrect the robot should he ever be destroyed; deducing Ultron will head for his old HQ if he escapes, the Vision departs intending to get there first. As the Avengers doggedly continue to fight, Ultron decides they are merely delaying him from his greater mission, destroying all mankind, and departs, smashing through the mansion’s outer wall. While the Avengers catch their breath and prepare to pursue, SHIELD locates the stolen Adamantium using a vibratory tracer and sends a squad to retrieve it. Unaware the Vision is hiding in the shadows, Ultron reaches his base and prepares to detonate every nuclear device stored there, confident that he will survive while the city is destroyed. The Vision attacks him, but Ultron stuns him and flies off. As Vision tries to pursue, arriving SHIELD agents, blaming Vision for the Adamantium theft, blast the synthozoid with their Vibro-Gun. In another part of the base the recently arrived Avengers witness some of the debris from the fight disintegrate, turned into energy; Yellowjacket deduces that Ultron needs only to pull one switch and an entire city will be wiped out.
