"You took everything from me"
-Scarlet Witch to Thanos
Wanda Maximoff is a native of Sokovia who grew up with her fraternal twin brother, Pietro. In an effort to help purge their country of strife, the twins joined HYDRA and agreed to undergo experiments with the Scepter under the supervision of Wolfgang von Strucker. The two received superpowers as a result, with Wanda attaining various abilities including telekinesis, telepathy, and energy manipulation. When HYDRA fell, the twins joined Ultron to get their revenge on Tony Stark over his weapons killing their family in a bombing, but eventually switched sides and joined the Avengers when they discovered Ultron's true intentions. Although Pietro was killed during the ensuing Ultron Offensive, Wanda survived and became a member of the Avengers. During the Avengers Civil War, she sided with Captain America and was briefly imprisoned in the Raft before Rogers freed her along with his teammates.
Over the next two years, Maximoff reunited and reconciled with Vision, and together the two started living off the grid in Europe, forming a romantic relationship. However, the two soon came under threat from Thanos and the Black Order, who sought the Mind Stone. After being ambushed by the Order, they sought refuge in Wakanda with the remaining Avengers. Maximoff partook in the city's defense when the Order launched a major assault against it, but was unable to stop Thanos from completing the Infinity Gauntlet; Maximoff was subsequently disintegrated in the Snap. After the effects of the Snap were undone in 2023, Maximoff was among the many heroes who fought during the Battle of Earth, defeating Thanos and his many armies.
