Wanda is first fully introduced in Avengers: Age of Ultron as the twin sister of Pietro Maximoff who can engage in hypnosis and telekinesis.[26][27] Olsen felt Wanda was "overly stimulated" rather than "mentally insane" because "she has such a vast amount of knowledge that she's unable to learn how to control it. No one taught her how to control it properly... she can connect to this world and parallel worlds at the same time, and parallel times".[27] Describing her character's mind control powers, Olsen said that the character is able to do more than manipulating someone's mind, with Scarlet Witch able to "feel and see what they feel and see" by projecting visions that they have never seen. Olsen expanded upon this, saying, "What I love about her is that, in so many superhero films, emotions are kind of negated a bit, but for her everything that someone else could feel—like their weakest moments—she physically goes through that same experience with them, which is pretty cool".[28] Olsen drew on her relationship with her older brother and her sisters to prepare for the role,[27] as well as looking to the comics for inspiration.[29] Olsen revealed that Whedon was inspired by dancers as a way to visually represent how the character moves.
