After the twins tell the Avengers of Ultron's plot, they, the Avengers, and Vision travel to Sokovia, where Ultron has used his remaining vibranium to build a machine capable of lifting a large section of the capital city skyward, intending to crash it into the Earth and cause global extinction. Wanda becomes overwhelmed by her role in Ultron's scheme until Barton befriends and encourages her to join the Avengers in stopping Ultron. Wanda volunteers to protect the machine's core from Ultron, but abandons her post to destroy Ultron's primary body after sensing Pietro's death, which allows one of his drones to activate the machine.
