A controversial Marvel character that most may want to see in Avengers: Doomsday or even Avengers: Secret Wars would arguably be Scarlet Witch or Wanda Maximoff, portrayed by Elizabeth Olsen. From being a hero in Avengers: Age of Ultron, she turned into a villain in Doctor Strange in the Multiverse of Madness. Inserting Wanda into the last two installments of the MCU makes sense, although it may not be happening.
Olsen was at C2E2 recently and was unsurprisingly asked about her future in the MCU. Surprisingly, the 37-year-old said she hardly had anything to spill and claimed she didn't know much.
