Why THAT Spider-Man & Jean 'Brand New Day' Scene Is Crucial To Her X-Men Future
One of the biggest reveals of Spider-Man: Brand New Day (2026) is the introduction of the Marvel Cinematic Universe’s Jean Grey. Played by Sadie Sink, Jean is a powerful telepath and telekinetic who is typically most famous as a member of the X-Men. In the MCU, she’s quickly introduced as one of the first overt mutants of the setting, laying the foundation for the franchise’s upcoming take on the mutant heroes. In this film, though, she’s largely positioned against Spider-Man as a dangerous antagonist and surprisingly sympathetic foil.
That all comes to a head in the climax of the film, which sees Peter finally let Jean into his mind and allow a memory of the late Aunt May, who died in Spider-Man: No Way Home (2021), to help convince Jean to back away from the moral lines she was about to cross. It’s a crucial moment in the Brand New Day, but it’s also fascinating for what it could say about the future of the character in the franchise. In fact, given Jean’s typically tragic arc in Marvel stories and her eventual evolution into the Phoenix, May’s words could become a key aspect of Jean’s full throughline in the franchise.
Why Jean Grey's Talk With Aunt May In 'Brand New Day' Is So Important
For most of Brand New Day, Jean is driven by fury. Her desire to be reunited with her sister, Sara, pushes her to make some morally suspect decisions, and her fury over the truth about William Metzger’s experiments on her leads Jean to endanger all of New York City.
However, while in Peter Parker’s mind, Jean gets the chance to experience the understanding of May Parker, who talks about how powerful someone may become but that they are still loved by their friends and family regardless. This is the key to Jean lowering her defenses and allowing Spider-Man to talk her down from endangering the city. It’s a key emotional beat that shows Peter and Jean finding a real moment of empathy. It’s also something that takes on a deeper meaning when the full history of Jean from the source material comes into play.
Jean's Power Levels Are Only Going To Keep Getting Stronger
Jean Grey is one of the most powerful mutants in the Marvel Universe. Although shows like X-Men: The Animated Series (1992) and X-Men: Evolution (2000) lean into her abilities as a telekinetic, they only tease her full potential that becomes unlocked when she bonds with the Phoenix Force. That cosmic entity combines with Jean in the original comics and in other adaptations like X-Men: The Last Stand (2006) and Dark Phoenix (2019), unlocking her full powers and helping establish her as an Omega-Level mutant with no real limits to her powers.
However, this comes at the cost of her losing touch with her humanity, often with disastrous consequences. This often sets the stage for one of the defining tragedies of the X-Men, wherein Jean ends up choosing her humanity at the cost of her power and her life. If the MCU X-Men are going to do an accurate reimagining of that storyline, it makes sense that they would want to start laying the groundwork for her eventual transformation. That’s what makes May’s words to Jean all the more important in Brand New Day.
An MCU Dark Phoenix Saga Could Revisit Aunt May's Words
A key element of May’s conversation with Jean is the sentiment that no matter how powerful someone may become and how monstrous others may see them, they can still be their true self and will be loved. In most iterations of the “Phoenix Saga,” Jean’s transformation into a galaxy-threatening force is tempered by the other X-Men helping ground her emotionally. Even if the world sees mutants as threats and alien cultures view the Phoenix as a monster, Jean retains enough humanity to stay true to herself. This decision, sadly, often comes with her death, ensuring she can’t be corrupted again.
As the Watcher notes in the original comics, “Jean Grey could have lived to become a God. But it was more important to her that she die, a human.” May’s words about Jean retaining her humanity and soul despite her growing power could be seen as an early tease of what Jean’s ultimate story in the MCU will be. Those words could even come back in future X-Men movies, serving as an important bookend for the character as she realizes her full potential but refuses to allow it to destroy countless lives. While Jean’s conversation with May is crucial to Brand New Day, it could become one of the defining elements of the character’s arc in future X-Men films.
