Mutant sorceress and former mutant terrorist
Wanda Maximoff is a beautiful red-haired woman of obvious Gypsy heritage. Her normal costume is a magenta body stocking, topped by a crimson coverup, gloves, boots, and cloak. She also normally wears crimson headgear that looks something like a crown, though this is occasionally replaced by a hood.
Scarlet Witch’s powers include high-level probability manipulation, energy projection for attack and defense, flight, and actual sorcery. She is a mutant as well as a practiced magic-user, and one of the most powerful of each on Earth.
Born at the Wundagore base of the High Evolutionary, Wanda and her twin brother Pietro are the children of Erik Lehnsherr (aka Magneto) and were eventually placed in the care of a Romani couple named Django and Marya Maximoff, from whom they were separated as teens when their encampment was attacked. They were later recruited into Magneto’s Brotherhood of Evil Mutants and, as the Scarlet Witch and Quicksilver.
The twins soon abandoned their terrorist activities and joined the Avengers. The remaining founding members had all gone on a leave of absence, leaving Captain America to lead an all-new lineup including Wanda, Pietro, and the archer known as Hawkeye. Although she became more adept in her power’s use, Wanda did not realize that she was tapping into genuine magic. It was believed that the Scarlet Witch would have been an ordinary energy manipulator or perhaps simply able to cause bad luck if not due to Chthon’s attempt to use her as a pawn.
Wanda fell in love with the synthezoid Vision, an artificial being created by Avengers foe Ultron who joined the team rather than fight them. The Scarlet Witch eventually married the Vision, and the two of them live in New Jersey while serving as active members of the Avengers. While the Vision is ostensibly the chairman of the team, he treats Wanda as his equal and co-leader in all ways. The two of them made the decision to begin starting Avengers teams in locations other than New York in order to safeguard America, and the experiment seems to be a success… so far.
