Wanda Maximoff (Elizabeth Olsen) has had a rough go of it ever since being introduced in Joss Whedon’s Avengers: Age of Ultron. In the same movie, she was manipulated by Ultron (James Spader), only to lose her brother Pietro (Aaron Taylor-Johnson) by the time all was said and done. Fast forward a movie and a half and she loses her lover in Vision (Paul Bettany) and is unable to bring him back by the time Avengers: Endgame wraps up.
Simple fan theory suggested new Villain
One tragedy after another could lead to the character turning the Marvel Cinematic Universe’s next big villain, according to one increasingly popular fan theory. Shared by u/cdhelt1225, the theory is simple enough — Maximoff’s undergone enough trauma to lay the groundwork for her to turn heel.
Similar to the early Mega-comic case
The theorist indicates this will occur by attempting to revive Vision to the point that she becomes a kind of Doctor Frankenstein that immediately causes her to change reality — something not unlike the House of M’s mid-2000s mega-comic case.
First, after the unsuccessful Sony / Disney agreement, it would be a way to explain Spider-Man’s rejection from the MCU, enabling him to switch universes somehow. It would then be a way to introduce the Disney-owned universe to both the Fantastic Four and X-Men, making it an organic way to introduce mutants to the ever-expanding globe.
Details about the sequel
This would also seem to play off the fact it’s been previously revealed the Doctor Strange sequel would take place immediately following WandaVision. Maybe it’d be the events of the Disney+ show that causes Doctor Strange (Benedict Cumberbatch) to track down Scarlet Witch through the multiverse, leading him to take on multi-dimensional beings like Nightmare, Dormammu, and Shuma-Gorath.
WandaVision hits Disney+ Spring 2021 while Doctor Strange in the Multiverse of Madness is scheduled for theatrical release on May 7, 2021.
