Wanda Maximoff, better known as the Scarlet Witch, was played by Elizabeth Olsen. She made her first appearance in the Marvel Cinematic Universe with Captain America: The Winter Soldier, but it was in The Avengers: Age of Ultron where her character really gained more relevance in the story. Although, so far, she last appeared in Avengers: Endgame, the Scarlet Witch is most likely set to come back to the big screen in other spin-offs. She will also have a leading role in the series WandaVision.
