Elizabeth Olsen voices the new Scarlet Witch version in at least one episode of Marvel's What If...? season 2,
which implies that the multiverse makes Scarlet Witch's MCU comeback conceivable.
Season 2 of What If...? allows viewers to follow new incarnations of the Scarlet Witch as the original Wanda Maximoff prepares to make her prophecy come true.
Although she hasn't formally left the MCU yet, Elizabeth Olsen is happy with Scarlet Witch's journey.
The second season of Marvel's "What If..." implies that Scarlet Witch will make an appearance in the MCU sooner rather than later.
Wanda Maximoff was hinted at by WandaVision as a major MCU character in the near future at the start of Phase 4.
The Scarlet Witch's enormous power "exceeds that of the Sorcerer Supreme. It is her destiny to destroy the world,"
as Agatha Harkness put it. Nevertheless, she appeared in one MCU film before being supposedly killed off by Doctor Strange in the Multiverse of Madness.
