Sadie Sink will reportedly reprise her top-secret upcoming Spider-Man: Brand New Day role in Avengers: Secret Wars.
That’s according to Deadline, which noted that the Stranger Things star would begin shooting 2027’s Avengers blockbuster later next year. (There’s currently no suggestion Sink will appear in Avengers: Doomsday.)
The revelation that Sink will return in Secret Wars has sparked a fresh wave of speculation around who she’s really playing. Marvel has kept her character’s identity firmly under wraps and seems happy to let debate rage over the various possibilities, with fans mostly split between her portraying a fresh villain or a new love interest for Tom Holland’s Peter Parker.
Top candidates for Sink’s role include X-Men character Jean Grey, cosmic villain Shathra, Punisher ally Rachel Cole-Alves and even Mayday Parker — here, fans hope, the daughter of Tobey Maguire’s Spider-Man.
Today’s report that Sink will reprise the role in Secret Wars seems to have nudged fans towards the latter — especially as it’s hoped that Maguire himself will return for one last appearance to round off the MCU’s Multiverse Saga.
“100% Mayday Parker or Firestar,” wrote Marvel fan HLumin on reddit. “It’s come to those two for me. I’m leaning more towards Mayday. Whoever she ends up being, we will not know until the post credit scene of BND. She will be someone else throughout the movie is my guess.”
Some fans have suggested that Sink’s mysterious identity will be part of Brand New Day’s plot, with her character’s true role something that Peter Parker discovers as the film unfolds. (And remember, the original Spider-Man: Homecoming took its time revealing exactly who Zendaya was playing.)
“Mayday makes the most sense at this point,” added Puzzled_Influence895. “She shows up as an unassuming side character like ‘Carlie Cooper’, helps Peter out… then drops the hammer and reveals the Tobey connection at the end, which brings him into the multiversal stuff.”
If so, we may still have some time to wait until Sink’s true identity is revealed. Spider-Man: Brand New Day arrives in theaters on July 31, 2026. Avengers: Secret Wars, meanwhile, is currently set for December 17, 2027. Here’s hoping we find out before then.
