MCU fans are rigorously debating Sadie Sink’s mystery character following the release of the Spider-Man 4 trailer.
Marvel Studios and Sony Pictures’ Spider-Man 4, also known as Spider-Man: Brand New Day, will be released in United States theaters this July. Directed by Shang-Chi and the Legend of the Ten Rings and Wonder Man’s Destin Daniel Cretton, the movie will once again see Tom Holland reprise his MCU role as Tom Holland/Spider-Man.
“Four years have passed since the events of No Way Home, and Peter is now an adult living entirely alone, having voluntarily erased himself from the lives and memories of those he loves,” the synopsis reads. “Crime-fighting in a New York that no longer knows his name, he’s devoted himself entirely to protecting his city — a full-time Spider-Man — but as the demands on him intensify, the pressure sparks a surprising physical evolution that threatens his existence, even as a strange new pattern of crimes gives rise to one of the most powerful threats he has ever faced.”
What are people saying about Sadie Sink’s Spider-Man 4 character after the new trailer?
Sadie Sink’s face isn’t actually seen in the Brand New Day trailer; however, MCU fans believe she’s still in the trailer. Many seem to believe that a scene with a character who has their back to the camera and another scene where someone is tied to a chair both feature Sink. This has led some to firmly believe that she’s most definitely playing X-Men character Jean Grey, as has been rumored for quite some time.

they really revealed NOTHING about sadie sink’s character except that hoodie shot… yeah they’re saving her for theatres. SHE IS JEAN GREY!!!!! pic.twitter.com/NOkWiqzsc3— ً (@softiealiaa) March 18, 2026
Others, however, think the opposite and believe the trailer confirms she is not playing Jean Grey.
Jean Theory Falls Apart After the Trailer ?The leaks contradict themselves. She wasn’t being hunted she was already captured, and the attack actually frees her. Damage Control isn’t against Spider-Man, they’re working together. And somehow, she ends up invading Peter’s house?… pic.twitter.com/YxQY3hYhSM— Marvel Mania (@Sksj002) March 18, 2026
Now that the full trailer has released, there’s absolutely no way she’s jean grey LOL https://t.co/XuqIvGAJqh— SMN*(Follow Back) (@Bludsprt_) March 18, 2026
Listen, I know she was already in Iron Fist but I personally haven’t ruled out Sink being Typhloid Mary. Her actions seem too outright villainous for pre-Phoenix Jean & the telepathy looking like a virus is a point in the “Typhloid” column. https://t.co/y9rjN61aVb— Lunwi (@lunwi75) March 18, 2026
In the end, we still don’t know for sure who Sink is playing in Spider-Man 4. Fans can find out for sure when the Marvel movie arrives on July 31, 2026.
