Sadie Sink Suits Up As Jean Grey In New MCU Art Ahead Of Spider-Man: Brand New Day

Sadie Sink makes for the perfect Jean Grey in new Marvel Cinematic Universe art ahead of the release of the first Spider-Man: Brand New Day trailer. Sink is no stranger to major franchises, as the actress played a key role on Netflix’s Stranger Things, Max Mayfield, for multiple seasons. With the end of Netflix’s hit show, Sink is now joining Spider-Man: Brand New Day‘s cast.

So far, Marvel and Sony have kept a lid on what role she plays in the MCU Spider-Man movie’s story. Sink has been rumored for several roles, including Spider-Man-related characters like Black Cat, Gwen Stacy, and even Mary Jane Watson, to other Marvel players like Rachel Cole and Jean Grey. The latter would impact the MCU’s X-Men movie, and it has become the most popular rumor for Sink’s role.

On Instagram, artist @subi.ozil imagines what Sadie Sink could look like as Jean Grey in Spider-Man: Brand New Day.

The MCU fan art sees the Stranger Things star donning Jean Grey’s iconic yellow and green suit from Marvel Comics. The costume includes a giant yellow phoenix on her chest, with Jean’s powers charging up her hands. Sink’s character can also be seen levitating, another Jean Grey skill.

The MCU fan art emerges as the perfect example of what Sadie Sink could look like in the Marvel movie, and it might not take too long for the franchise itself to reveal if that is an accurate representation of the role the actress plays. After all, Tom Holland confirmed this Tuesday, March 17, that the Spider-Man: Brand New Day trailer will be released on Wednesday, March 18.

Spider-Man: Brand New Day’s Trailer Release Strategy Is Perfect For The 2026 MCU Movie

Tom Holland has officially confirmed the Spider-Man: Brand New Day trailer’s release date, and the MCU has the perfect strategy for its next movie.

Before that, Sony is promoting a different kind of trailer rollout, with Spider-Man: Brand New Day snippets being released throughout the day by select Marvel fans from different countries. At the time of writing, Sink’s mysterious character is not present in any of the Marvel teasers. However, that could change by the end of the day before Sink is likely shown in the movie’s full trailer.

Before she was ever confirmed to appear in Spider-Man: Brand New Day, Sadie Sink was rumored to be Marvel’s frontrunner for Jean Grey. As such, it makes sense that she would play that role in the 2026 film. Helping that rumor is the fact that the Stranger Things actress is reportedly returning in Avengers: Secret Wars. She has to be playing a sizable role.

Having Jean debut in Spider-Man: Brand New Day before appearing in Avengers: Secret Wars, where the MCU will be rebooted, and the new X-Men will be set up, would be perfect for the character. Jean would have two high-profile appearances under her belt before the MCU’s first X-Men movie came around.

Additionally, Sink not only looks like the hero, but she has also shown the skills to bring Jean’s empathetic, fierce, and determined persona to life. What weighs against the casting is that Spider-Man: Brand New Day is said to be a street-level story, and not only does Jean Grey not exactly fit that, but she’s not a Spider-Man franchise character. Perhaps Spider-Man: Brand New Day‘s trailer will end the speculation.
