As the excitement for Marvel’s upcoming projects in 2026 continues to build, fans are particularly eager to learn more about two major releases. While much of the attention has been on the highly anticipated Avengers: Doomsday set for December, there’s also a lot of curiosity surrounding the late-summer release, Spider-Man: Brand New Day. This film is expected to bring back Tom Holland as Spider-Man, along with several new characters, one of whom is the popular Stranger Things star Sadie Sink.

The mystery around Sink’s role in the film has sparked endless speculation among fans. With her joining the Marvel Cinematic Universe, questions about who she will play have become a hot topic across social media platforms. However, Marvel has remained tight-lipped about the details, keeping many aspects of the movie under wraps.

Theories About Sadie Sink’s Role in Spider-Man: Brand New Day

Fans have come up with numerous theories about which character Sink might portray in the film. Some believe she could be playing Gwen Stacy, while others think she may have a connection to Jon Bernthal’s Punisher. There are also theories suggesting that she could be playing a villain in the movie, with some speculating that she might take on roles such as Shathra, Black Cat, or even Screaming Mimi/Songbird.

Another theory suggests that Sink could be playing Julia Carpenter, also known as Madame Web. Meanwhile, some fans have speculated that she might be portraying Mayday Parker, the alternate identity of Spider-Man.

Despite the variety of theories, there’s no official confirmation from Marvel regarding Sink’s role. However, her recent comments have added a bit more clarity to the situation.
