Wanda Maximoff (also known as Scarlet Witch) is a Marvel Comics character who has appeared in many Marvel-related productions. In the Marvel Cinematic Universe, she first appears as a cameo in the mid-credits scene of 2014's film Captain America: The Winter Soldier, and becomes a more prominent character after returning in 2015's Avengers: Age of Ultron. She and Vision are the titular protagonists of the Disney+ series WandaVision. Wanda is the twin sister of Pietro Maximoff, alias Quicksilver. She started out as a vengeful lackey to the evil Ultron, before redeeming herself and joining the Avengers following the death of her brother, who would have done likewise if he had lived. Wanda was born in the country of Sokovia alongside her older twin brother Pietro. They became orphans when a mortar shell hit their house while they were having dinner. Years later, Sokovia became a war zone. She and her brother participated in different riots in an attempt to drive the foreign forces out of their country. However, all these riots were planned by HYDRA, who had taken up residence in Sokovia and used the riots as cover for their illegal experiments. One day, List, a HYDRA scientist approached them to offer the opportunity to get enough power to drive war out of Sokovia. Wanda was skeptical but was finally convinced by Pietro. As a result of these experiments, she won numerous mental powers such as telekinesis, hypnosis, and energy projection; while Pietro achieved superhuman speed.
