Wondering what roles Sadie Sink might play in Spider-Man 4 and how she could fit into the Marvel Cinematic Universe? With Tom Holland’s Peter Parker continuing his story after No Way Home, there’s speculation she could be a new love interest, an X-Men character entering the MCU, or involved in the ongoing multiverse storylines.
Here’s a breakdown of every character Sadie Sink is rumored to play in Spider-Man: Brand New Day.
List of all characters Sadie Sink is rumored to play in Spider-Man 4: Brand New Day
Sadie Sink is generating buzz after being chosen for the new Marvel movie, Spider-Man: Brand New Day. Since news of her casting in March, people have been guessing about her character, and some reports indicate she might have superpowers.
A fan account, @MyTimeToShineHello, shared a rumor that Sadie Sink’s character in the show has superpowers. Sink responded to Josh Horowitz on the Happy Sad Confused podcast, playfully denying the claim. She said she hadn’t heard anything about it, but admitted the rumor was “really cool” and that she enjoyed reading it, praising her character as a “great character.”
Jean Grey
A popular rumor suggests that actress Sydney Sweeney could play Jean Grey, also known as Marvel Girl. If true, this would bring the X-Men into the Marvel Cinematic Universe. However, Den of Nerds points out that the character Kang seemingly removed the mutant gene from this timeline, which could impact how the X-Men are introduced.
Carlie Cooper
Carlie Cooper is a police officer first introduced in the Brand New Day Spider-Man comics. She develops a romantic relationship with Peter Parker, but eventually becomes the supervillain known as Monster.
Mayday Parker / Spider-Girl
There’s been talk that Mayday Parker, the daughter of Tobey Maguire’s Spider-Man, might also have spider-powers and could appear in the Marvel Cinematic Universe to help Tom Holland’s Spider-Man.
Firestar (Angelica Jones)
Firestar is a mutant who can control fire, and she’s fought alongside both the Avengers and the X-Men. Introducing her could help link Spider-Man’s adventures to the larger story of the Marvel Cinematic Universe.
Gwen Stacy
As a huge Spider-Man fan, I’ve always thought Gwen Stacy was a key part of Peter Parker’s story, and it’s exciting to see Marvel isn’t afraid to put their own spin on classic characters. They’re definitely hinting at exploring that relationship again, and I’m all for it!
Julia Carpenter
Jessica Drew, who has also been known as Spider-Woman and Madame Web, could help connect Peter Parker’s stories with those of Kamala Khan and the Young Avengers, potentially setting up future team-ups.
Mary Jane Watson
While Zendaya plays Michelle Jones, some fans believe Sadie Sink might be cast as the original, red-haired Mary Jane Watson, potentially tying into the storyline of Venom.
Rumors indicate she might play Rachel Cole-Alves, a crime fighter associated with the Punisher, or Janice Lincoln, the daughter of the villain Tombstone who goes by the name Beetle.
With Spider-Man: Brand New Day set for July 2026, Marvel has not confirmed Sink’s character.
