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 drew attention after being cast in Marvel Studios’ upcoming film Spider-Man: Brand New Day. Since her casting in March, speculation about her role has only grown, with reports suggesting the character may wield superpowers.
Scooper @MyTimeToShineHello posted, “I hear that Sadie Sink’s character has super powers!” while Sink herself told Josh Horowitz’s Happy Sad Confused podcast, “This is news to me. This is news to me. No, I have nothing to say about this. The rumours are really cool, though. It’s an awesome rumor. I know the character. It’s a great character, so that was cool to read.”
Jean Grey
One of the strongest rumors links Sink to playing Jean Grey in her Marvel Girl form. This would introduce the X-Men to the MCU, with Den of Nerds noting Kang “kind of” erased the mutant gene in this timeline.
Carlie Cooper
An NYPD officer from the Brand New Day comics who becomes Peter Parker’s love interest and later transforms into the villain Monster.
Mayday Parker / Spider-Girl
Speculated as Tobey Maguire’s Spider-Man daughter, Mayday Parker, who inherits spider powers and could cross into the MCU timeline to assist Tom Holland’s Peter.
Firestar (Angelica Jones)
A mutant with fire-based powers, Firestar has been both an Avenger and an X-Men member. She could connect Spider-Man’s solo story to broader MCU arcs.
Gwen Stacy
Another possible love interest, Gwen, has long been central to Peter’s narrative. Marvel Studios has shown a willingness to reinterpret iconic characters.
Julia Carpenter
Known as Spider-Woman and Madame Web, Carpenter could tie Peter’s adventures to Kamala Khan’s Young Avengers storyline and future team connections.
Mary Jane Watson
Though Zendaya’s MJ is Michelle Jones, rumors suggest Sink may portray the classic red-haired Mary Jane, possibly connected to Venom’s appearance.
Additional reports suggest she could portray Rachel Cole-Alves, a vigilante linked to the Punisher, or Janice Lincoln, Tombstone’s daughter known as the Beetle.
With Spider-Man: Brand New Day set for July 2026, Marvel has not confirmed Sink’s character.
