 * Pietro and Wanda Maximoff find Ultron in the base.

While the body is being made, Ultron takes the Mind Stone out of the scepter and places it on the android's head. Through the body, Wanda finds out that Ultron plans to kill all of the human race.

In the center of the city, a drill is creating a magnetic field to help keep the city in the air. Soon, Nick Fury arrives with Helicarrier No. 64, and a few former S.H.I.E.L.D. agents, including Maria Hill and Cameron Klein. They deploy transporters for people to board and escape the city safely. The Avengers regroup at the drill, fighting off Ultron and his drones so he can't activate it. Ultron's body is heavily damaged, forcing him to retreat. As sentries try to attack the Helicarrier, War Machine joins the fight, having reverted back to War Machine following Iron Patriot, and stops the sentries. Ultron, critically damaged, hijacks the Avengers' Quinjet and begins using it against them. Hawkeye exits one of the lifeboats to save a young boy, but Ultron sees them and begins shooting at them. Pietro shields them from the attack, resulting in him being shot and dying. Hulk leaps into the Quinjet and throws Ultron out of it. Believing that the team is constantly in danger because of him, Hulk cloaks the Quinjet, disables all forms of communication, and puts it on autopilot. The Quinjet flies to places unknown with Hulk inside.
