Is Jean Grey entering the Spider-Verse

Latest leak sets fandom alight as clip fuels fresh speculation over Sadie Sink's undisclosed character

Sony has had trouble keeping many key elements of 'Spider-Man: Brand New Day' under wraps, from its added cast members to its initial trailer leaking well before release. Now, it has suffered a second trailer leak, this one worse than the first, according to various media reports.

A fresh wave of speculation has swept through Marvel fandom after a reported merchandise leak appears to reveal the long-guarded mystery surrounding Sadie Sink's role in the upcoming 'Spider-Man: Brand New Day', intensifying anticipation for one of 2026's most closely watched superhero releases.

The film marks Tom Holland's return as Peter Parker after nearly five years, with the story picking up in a fractured reality where the world has forgotten his civilian identity, even as Spider-Man remains widely recognised.

Alongside Holland, Zendaya returns as MJ and Jacob Batalon reprises his role as Ned Leeds, while Marvel stalwarts Mark Ruffalo and Jon Bernthal are also set to reappear as Bruce Banner and Frank Castle respectively.

Yet it is Sink's undisclosed character that has fuelled the loudest speculation since her casting was announced. The 'Stranger Things' actor has featured briefly in promotional material, but Marvel and Sony have so far withheld any official confirmation of her role, preserving the secrecy that has become a hallmark of major MCU releases.

That mystery may have been cracked open by what appears to be leaked promotional merchandise. According to reports circulating online, an image of a bag clip-style figure has surfaced, strongly hinting that Sink could be portraying X-Men character Jean Grey.

The figure reportedly resembles Sink's on-screen look in trailers, including her distinctive red hair, while also depicting pink energy effects emanating from her hands and eyes, widely associated with Jean Grey's mutant abilities.

The alleged leak has not been independently verified by Marvel or Sony, and no official product release has confirmed the character identity. However, the imagery has already prompted widespread debate among fans, many of whom now believe the evidence points increasingly towards the introduction of Jean Grey into the Spider-Man franchise.

Initial rumours of Sink playing Jean Grey emerged soon after her casting, though they were met with scepticism given the character's strong ties to the X-Men universe rather than Spider-Man's traditional storyline. However, the expanding scope of the Marvel Cinematic Universe and its gradual move towards mutant-centric narratives has given those theories renewed credibility.

Industry observers note that 'Spider-Man: Brand New Day' is expected to play a pivotal role in setting up Marvel's next major narrative phase, often referred to informally as the "Mutants era". Within that framework, crossovers between Spider-Man and mutant characters would not be without precedent, drawing on comic book arcs and animated adaptations where such intersections were frequent.

Further fuelling speculation are claims that Sink's character may possess abilities involving control or possession of others, a trait loosely aligned with certain interpretations of Jean Grey's powers, particularly when linked to the Phoenix Force storyline. Reports also suggest that Spider-Man may be uniquely resistant to these abilities within the film's narrative, adding another layer to the suspected connection.

The colour palette seen in promotional material has also been scrutinised, with fans pointing to recurring yellow tones associated with Sink's character as another possible nod to Jean Grey's traditional comic book design.

Despite the mounting theories, Marvel Studios and Sony Pictures have maintained silence, and insiders caution that merchandise leaks have previously proven misleading or incomplete. With major franchises often guarding final character reveals until release or late-stage marketing campaigns, confirmation may still be some time away.

Until then, speculation continues to build around Sink's role, with 'Spider-Man: Brand New Day' increasingly positioned not just as a continuation of Peter Parker's story, but potentially as a gateway into Marvel's next evolutionary chapter.

The new leaked 'Spider-Man: Brand New Day' trailer is in incredibly high quality, and despite a red X and "property of Sony" stamped on it, is practically ready for release, it seems. 'Spider-Man: Brand New Day' arrives in theatres on July 31.
