Over the years, the MCU has been teasing the arrival of mutants, but ‘Brand New Day’ might be the project that finally brings them to the forefront. The idea has been in the shadows for a while. But that may be about to change, in a big way.
Sadie Sink has been rumored to be playing Jean Grey, one of Marvel’s most iconic mutant heroes. There is no word from Marvel yet on her role, but it’s becoming harder for fans to look past the clues.
‘Spider-Man: Brand New Day’s Biggest Mystery May Be A Mutant

The most interesting part is the enigmatic psychic danger that lies at the heart of the narrative. The trailers suggest telepathic and mind-altering powers, which immediately conjure up the image of Jean Grey.

Fueling the speculation even more is the fact that Bill Metzger, a comic-book character who is closely associated with anti-mutant sentiment, is present. In the movie, he is linked to the Department of Damage Control and explains that there is a dangerous force that is not under his control.
The pieces appear to be fitting for many fans. The MCU has been building up a lot of buzz for its take on Jean Grey, thanks to a powerful telepath, anti-mutant tension, and Sadie Sink. As you might expect, Marvel is known for its misdirection. The studio has managed to pull off some big surprises before. And there’s always a possibility that Sink is a different character altogether.
Why The Timing Makes Sense For Marvel

Even if Marvel keeps the official reveal under wraps, ‘Brand New Day’ seems like a great place to extend the mutant story. The film comes out right before ‘Avengers: Doomsday’, one of the MCU’s largest crossover movies to date.

Marvel has got to find a way to make mutants a major part of its universe, and not just a bunch of characters who are visiting from other realities. A big name like Jean Grey would help fill that void. There’s also a feeling that the MCU is in a new phase.
The Avengers were the foundation of the Infinity Saga. The Multiverse Saga has ventured into other worlds and timelines. The franchise now seems to be setting up the mutant era. ‘Spider-Man: Brand New Day’ will not only be Peter Parker’s next adventure. It could be remembered as the movie that finally brought the X-Men into the heart of the MCU.
