2 Spider-Man: Brand New Day Trailers Ignite 20,000 Fan Theories Ahead of Next Month

Q: With Jean Grey heavily rumored, who is the true villain Tom Holland insists no one has correctly guessed for 'Brand New Day'?

The true villain has not been publicly identified. Despite heavy rumors around Jean Grey, Tom Holland has said fans have not correctly guessed the main antagonist of “Spider-Man: Brand New Day,” and available reporting still treats that identity as a secret. What is known is that Sadie Sink is widely rumored to be playing Jean Grey, and some insider reports say she could be tied to the film’s telepathic threat. But the coverage also stresses that Jean Grey may not be the ultimate villain, especially if her role involves manipulation, possession, or a larger unseen force. The strongest clue comes from the film’s setup: Peter Parker is said to be trying to stop “a powerful villain no one can even see.” That has kept speculation focused on possibilities such as an invisible or psychic antagonist, with names like Mister Negative, The Jackal, Mister Sinister, Shathra, Spider-Queen, or even William Metzger circulating online. None of those, however, has been confirmed. So the direct answer is that the villain Holland is referring to remains unknown. Jean Grey is a major rumor and may be central to the plot, but there is no verified evidence that she is the true main villain he says nobody has guessed.

Q: Will Sadie Sink’s secret role be the key to finally integrating the X-Men into the mainstream MCU, permanently altering its future?

Probably not on its own. The strongest reading of the available evidence is that Sadie Sink’s role in *Spider-Man: Brand New Day* could be an important bridge to the X-Men, but not the single event that permanently reshapes the MCU. The speculation around Sink is unusually intense because Marvel has kept her character secret while trailers and insider reports point toward a telepathic, mutation-linked storyline. The leading theory is that she is playing Jean Grey, with other guesses including Rachel Summers, Madelyne Pryor, Hope Summers, or even a non-mutant misdirect. Reports from test screenings have added weight to the Jean Grey theory, and the film’s references to “mutating DNA,” body-swapping, and an unseen psychic threat all fit an X-Men-adjacent reveal. If Sink is Jean Grey, that would be a major step: it would place a core mutant figure inside a mainstream Spider-Man film and signal that Marvel is moving mutants from teases into central continuity. That matters because *Brand New Day* appears designed as both a mystery and a pivot point, with Peter Parker’s transformation and memory-erasure fallout creating room for a larger mythology shift. But the broader MCU change is expected to come through *Avengers: Secret Wars*, not this film alone. Current reporting indicates *Secret Wars* is the project intended to consolidate timelines and place mutants at the center of Marvel’s next era. In that scenario, Sink’s role would be an early doorway, not the final key.

Sadie Sink’s undisclosed role has become a major focus, with theories ranging from Jean Grey and Mayday Parker to Rachel Summers, Madelyne Pryor, Hope Summers and even Shathra.
Mark Ruffalo’s Hulk footage has fueled separate guesses that Marvel is reviving Savage Hulk or setting up a fight before revealing a body-hopping enemy behind the chaos.
