Scarlet Witch returns to the Avengers during the events of Avengers vs. X-Men. Found by Ms. Marvel and Spider-Woman, Wanda is offered back her place among the Avengers, and despite her initial reluctance, upon Ms. Marvel insisting on taking her, she accepts and follows them to Avengers Mansion. However, despite both heroines pleading her case, the Vision angrily snaps at Wanda, blaming her again for having manipulated and killed him, and telling her to leave. Despite both Ms. Marvel and Iron Man rushing to Wanda's defense, the Avengers ultimately defer every decision to the Vision, who elects to stand by his point, even if obviously pained by the situation: thus, Ms. Marvel has to carry away a crying Wanda. When the Avengers go to extract Hope Summers from Utopia and are nearly defeated by a Phoenix Force-empowered Cyclops, Scarlet Witch arrives and saves them. Hope agrees to go with the Scarlet Witch, and Wanda causes physical harm to Cyclops when he touches Wanda's arm when he tries to stop her from taking Hope.
Though hunted by the Phoenix-powered X-Men, Wanda's return to the team provides the Avengers a much needed boost as many teammates are captured by the X-Men. Hawkeye ultimately is severely injured rescuing Wanda from being teleported away by Magik and White Queen, the former of which sees Wanda as a monster for depowering mutantkind. However, Wanda's power provides the X-Men with a threat that not even the Phoenix can face down as the Avengers employ magical illusions to trick the X-Men into thinking Wanda is with the various Avengers groups. Further investigation meanwhile links Wanda's powers to the Phoenix Force. When Cyclops goes Dark Phoenix, Wanda and Hope Summers, who is mimicking Wanda's powers, defeat him and cause the phoenix force to leave him. After Hope inherits the Phoenix Force, she and Wanda combine their powers to apparently destroy the Phoenix by saying "No more Phoenix". This results in the repowering of mutants, undoing Wanda's actions on M-Day.
Following the war, Captain America selects Scarlet Witch to join the Avengers Unity Squad, a new team of Avengers composed of both classic Avengers and X-Men.
