Wanda Maximoff is a native of Sokovia who grew up with her 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, and 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, but eventually switched sides and joined the Avengers when they discovered Ultron's true intentions.
