Elizabeth Olsen’s Scarlet Witch and Joe Locke’s Wiccan are more similar than they seemed at first during Agatha All Along, as evidenced by a bittersweet fan-made MCU footage compilation. Marvel Studios has adapted Wanda Maximoff’s complex comic book history in the MCU’s timeline, creating an MCU Scarlet Witch journey that encompasses her time as an Avengers enemy, an official Avenger, a novice witch, an unintentional criminal, and a full-fledged supervillain. Likewise, the MCU incorporated Wiccan’s tricky origin story from the comics into Phase 5, setting up Speed’s return and the Young Avengers’ introduction along the way.
