Scarlet Witch

Wanda Maximoff, also known as Scarlet Witch, is a native of Sokovia who grew up with her fraternal twin brother, Pietro. Born with the latent magical ability to harness Chaos Magic, she developed a hatred against Tony Stark and rallied anti-American protests after the Novi Grad Bombings, which killed her parents. Years later, 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, amplifying her abilities. While her brother developed super-speed, Wanda attained various psionic abilities. When HYDRA fell, the twins joined Ultron to get their revenge on Stark, but abandoned him when they discovered Ultron's true intentions to destroy Earth. Wanda and Pietro joined the Avengers during the Battle of Sokovia to stop Ultron; Pietro was killed during the battle but Wanda survived, and shortly after moved to the United States.
