Scarlet Witch

Wanda Marya Maximoff is a native of Sokovia, an Avenger and the twin sister of Quicksilver. After discovering that she is, in fact, the long ago prophesied Scarlet Witch, and supposedly destined to destroy the world, she began studying the Mystic Arts to better control her powers. She became an ally of the Sorcerer Supreme and a student of the Sorceress Eternal.
