Disney might have to complete its acquisition of 20th Century Fox, but with the merger on the way, it looks like Marvel is planning to turn the Marvel Cinematic Universe's Scarlet Witch (Elizabeth Olsen) into a mutant like the X-Men and Fantastic Four.
According to a report by Screen Rant, new information from the Marvel Studios Visual Dictionary has been raising the potential of a retconned origin for Scarlet Witch. Though the character is usually depicted as a mutant in comics, Marvel had to rewrite Wanda and Pietro Maximoff's origin in the MCU because the studio didn't have the rights to use the word "mutant" in the franchise with the X-Men license being owned by Fox.
However, now that the merger between the Mickey Mouse House and Fox seems inevitable, it looks like Marvel is preparing for a new canon that could retcon Scarlet Witch and Quicksilver as mutants.
Here's what's written in the recently published Visual Dictionary:
"She may be called Scarlet Witch, but Wanda's powers aren't derived from the occult. Whether it altered her or merely unlocked something latent inside Wanda, the Infinity Stone on Loki's scepter bestowed incredible powers of the mind. Wanda's internal neuro-electric interface allows her to conjure blasts of red telekinetic energy. She can also use this energy to create barriers, levitate and move objects; to communicate and read thoughts by telepathy, and even to manipulate the minds of others."
Though the description for Wanda tries to follow the original backstory the MCU has for Scarlet Witch and Quicksilver (wherein the young Sokovian siblings gain their powers after exposure to the Mind Stone), it also suggests that the Mind Stone might have actually "altered" and "unlocked" a power latent inside the character.
Sure, Marvel might have to retcon a few more other things about Scarlet Witch like the true story of her parentage, but it looks like the studio has begun laying the groundwork for Wanda's new backstory.
