Sadie Sink, who rose to fame through her performance in Stranger Things, has now officially made the leap into the Marvel Universe, and joined the cast of Spider-Man 4 – although there are scarcely any details regarding her role in the film. Fans are left to speculate about which character she may portray and have landed on a number of possibilities. Is it Jean Grey or Mary Jane Watson? Or could she be playing Black Cat?
A common theory is that Sink could show up as Jean Grey, the telepath and telekinetic powerhouse of the X-Men. Speculating about this is not completely off base; back in December 2022, several outlets were reporting that Sink was one of the top contenders to play the iconic Marvel role in an X-Men reboot. Introducing Jean Grey in Spider-Man 4 could serve as a strategic way to integrate the X-Men into the Marvel Cinematic Universe.
Another possibility is that Sink could play Mary Jane Watson, Parker’s iconic, red-haired, love interest. While Zendaya’s character, Michelle “MJ” Jones, exists in the current Spider-Man storyline, she is very different from the traditional Mary Jane found in the comics. With the end of Spider-Man: No Way Home erasing Peter’s existence from everyone’s memory, introducing Watson as a separate entity could rewrite Parker’s relationship with his famous other half.
There has also been fan speculation that Sink could play either Gwen Stacy or Felicia Hardy (Black Cat). Both characters have lengthy and fascinating histories with Spider-Man. They would also be very good candidates to introduce some fresh and interesting plotlines into the franchise. Not only is Gwen Peter’s first true love, but Black Cat is also a complex anti-heroine with a long association with Spidey.
A recent leak suggests that Spider-Man 4 might explore the multiverse once again. If it does, Sink could be playing a different reality version of a character fans know. She could be a Mary Jane variant who gets spider-like powers. Or she could be a different version of Spider-Gwen. Who knows? This all seems pretty speculative. But this approach would align with the MCU’s recent exploration of parallel universes and offer fans a new perspective on beloved characters – like Sony did with the Spider-Verse films.
The casting announcement has sparked discussions on many platforms. Fans on Reddit are all a-buzz with excitement and even theories about Sink’s role. One user said, “Sadie Sink as Jean Grey would be a dream come true! She has the perfect look and acting chops for the role.” Another fan on a different thread said, “What if she’s playing Spider-Gwen? That would be an epic addition to the MCU!”
With production swiftly moving forward on Spider-Man 4, which is directed by Destin Daniel Cretton and scheduled to be released on July 31, 2026, fans await word from Marvel Studios regarding the character that Sink will portray. Will she take on Jean Grey? Mary Jane Watson? Another iconic character? Whatever it is, Sadie Sink’s dynamic presence assures that Spider-Man 4 will be something special for fans.
