The internet has been spending months trying to figure out who “Stranger Things” actress Sadie Sink is playing in the Marvel Cinematic Universe (one of the few open-ended Marvel mysteries), as her role in Destin Daniel Cretton‘s “Spider-Man: Brand New Day” as it’ll reportedly carry over to a return in “Avengers: Secret Wars.”
There have been all sorts of character speculation from Marvel Girl/Jean Grey to Angelica Jones/Firestar to a Multiverse variant of Mayday Parker/Spider-Girl/Spider-Woman (daughter of Peter Parker and Mary Jane Watson, who appears as a baby in the “Spider-Verse” films), all seemingly centered around the Sink’s red hair. The latest guess from the internet is that she is playing Frank Castle’s (Jon Bernthal) redheaded comic book sidekick/protege, Rachel Cole-Alves (Let’s add that to the pile of character theories).

Sink specifically commented on that Jean Grey speculation to Entertainment Weekly (that rumor felt highly unlikely since a Sony-owned film doesn’t feel like an entry point for such a key mutant character with an “X-Men” reboot in the works), “That was happening before I even knew that I would be working on this project…I was like, ‘Wait! What are people talking about?’…A lot of people forget that hair color can change, but, yeah, I understand all of the theories.”
Whatever the case, we likely won’t have to wait too much longer to learn more about Sink’s MCU role, as CinemaCon in April will be a promotional event where Sony may reveal more details about the “Spider-Man” sequel, including the reveal of who exactly Sink is playing in it and revealing what exactly the threat of the film is going to be, including why Mark Ruffalo‘s Banner/Hulk is showing up in it.
“Spider-Man: Brand New Day” is set to swing into theaters on July 31, 2026.
