Wanda Maximoff first appeared in the Marvel Cinematic Universe (MCU) in the post-credit scene of Captain America: The Winter Soldier, and then had a prominent role in Avengers: Age of Ultron. She is portrayed as a powerful mutant with the ability to manipulate reality and energy, and has a complex backstory involving her involvement with HYDRA, her twin brother Pietro (Quicksilver), and her connection to the Mind Stone.
In the most recent MCU series, WandaVision, Wanda is portrayed as dealing with the trauma of losing her family and creating a new reality for herself in the town of Westview. The series also introduces new aspects of her character, such as her expanded powers and her role as the Scarlet Witch, a title that has not been used in the previous MCU films.
Doctor Strange in the Multiverse of Madness is an upcoming MCU film that will feature both Wanda and Doctor Strange. The plot of the film has not been officially confirmed, but it is rumored to involve the multiverse and various alternate realities. It is possible that Wanda’s reality-warping powers could play a significant role in the film’s plot.
Given the information available, it is impossible to say definitively whether or not Wanda dies in Doctor Strange in the Multiverse of Madness. However, it is worth noting that characters in the MCU have a history of both dying and being resurrected, and that Wanda is a popular and well-established character who is likely to have a continued presence in the franchise.
It is also worth noting that the MCU has been known to deviate from comic book canon in significant ways, so even if there is a storyline in the comics where Wanda dies, it is not necessarily indicative of what will happen in the films. Additionally, Marvel Studios and Disney have been tight-lipped about the plot of upcoming films, so it is possible that even leaked rumors may not be entirely accurate.
In summary, there is no definitive answer to the question of whether or not Wanda dies in Doctor Strange in the Multiverse of Madness, as the plot of the film has not been confirmed and even rumors may not be entirely accurate. However, given the popularity of the character and her expanded role in recent MCU series, it seems likely that she will continue to play a significant role in the franchise regardless of her fate in the upcoming film.
