Outside Avengers Mansion, onlookers are horrified to see a series of explosions emanating from the building. Inside, things are not much better as the Avengers are facing off against the rebuilt Ultron-6. The situation only gets worse when Thor attempts to strike Ultron with Mjolnir. When the enchanted hammer comes in contact with Ultron’s new adamantium body, the Avengers are thrown back by the shockwave, knocking out Thor and Goliath. Meanwhile, Vision is elsewhere in the mansion attempting to come to grips with the betrayal he has just committed against his teammates.
With their powerhouses disabled, Iron Man, Wasp and Yellowjacket desperately attempt to hold off Ultron’s attacks. In spite of their desperation and with Iron Man’s weakened state the trio are make so much as a dent and Ultron departs the mansion to further his own plans. Thankfully for Yellowjacket, Goliath regains consciousness in time to catch him as he falls off the departing Ultron. In all of this confusion Vision is able to quietly exit the mansion, hoping to beat Ultron to his destination.
Regrouping after barely surviving the assault, the Avengers decide to begin their hunt for Ultron at his former secret headquarters, unaware that Vision has already arrived in that exact location. As the genocidal android examines his equipment, Vision, the Avengers and even a S.H.I.E.L.D. team converge on him. Vision is the first to encounter him, and while the Avenger initially makes some headway against his former master, Ultron unveils his latest ability. Transforming himself into pure ionic force, Ultron disables Vision and continues on with his mission. As Vision is forced to confront the S.H.I.E.L.D. team, the Avengers make their way through the headquarters. Unfortunately their progress is cut short as equipment within the structure starts to convert into energy. Much to their horror, Yellowjacket declares that Ultron is only a single switch away from wiping the entire city off the face of the earth.
