Wanda Maximoff a.k.a. Scarlet Witch
By the time it’s all wrapped up, WandaVision essentially proves to be a superhero therapy session for Wanda Maximoff – and one that further develops the character as one of the most powerful in all of the Marvel Cinematic Universe. As revealed by Agatha Harkness, Wanda isn’t just some ordinary girl from Sokovia who got powers from an Infinity Stone, but instead a legendary agent of chaos magic who has the capacity to totally change reality at her whim. Gaining this understanding and managing her grief through her experience in Westview, she is put on a wholly new path in the wake of the Disney+ show, and one that will apparently only see her enhance her abilities further. In the “Series Finale” post-credits scene, Wanda is shown not only living in isolation, but also further honing her incredible skills as the Scarlet Witch, and while doing so she receives a faint but important message (more on that in a bit).
