Wanda Maximoff is a native of the Eastern European country of Sokovia who grew up with her twin brother, Pietro. In an effort to help purge their country of strife, the twins agreed to undergo experiments with the Scepter under the supervision of Wolfgang von Strucker's HYDRA cell, and achieved superpowers as a result, with Wanda attaining various abilities including telekinesis, telepathy, and energy manipulation. When HYDRA fell, the twins joined the robot Ultron to get their revenge on Tony Stark, 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.
