Disputed Spider-Man: Brand New Day Image Revives Jean Grey Speculation Around Sadie Sink

The unverified photo has sharpened focus on a secret role that reporting ties to a return in Avengers: Secret Wars.

Overview

  • A purported still circulating Wednesday shows Sadie Sink beside Jon Bernthal’s Punisher, with a visible Gemini logo raising questions about AI enhancement and the image’s authenticity.
  • Forbes and other outlets report that prominent leakers now lean toward Sink portraying Jean Grey, though no studio has confirmed her character.
  • ComicBook.com notes Marvel’s unusual secrecy around Sink’s role, which many read as a sign of a major reveal rather than a lesser-known character.
  • The Gemini watermark matters because Google’s AI upscaler can stamp images it processes, a detail that can blur the line between a touched-up leak and a fabricated picture.
  • Earlier leaks for Brand New Day included a trailer and promo art, and separate reporting says Sink’s character is slated to appear in Avengers: Secret Wars ahead of the film’s July 31, 2026 release.
