SPIDER-MAN: BRAND NEW DAY Will Reportedly See Peter Parker Start to Transform Into Man-Spider
While we continue to wait for Sony and Marvel to release a trailer for Spider-Man: Brand New Day, a new report has surfaced suggesting Peter Parker’s next chapter in the MCU is going to get seriously strange.
According to John Campea, some recent plot details floating around online are legit, even if they didn’t come from an “official studio source.” The big hook centers on Peter’s genetics.
The spider bite didn’t just give him powers. It altered him on a deeper level, and now that change may be spiraling out of control.
Campea says, "In the vein of Jeff Goldblum in The Fly, we're going to see Peter mutate into a spider being...literally mutating into a spider. One of the main things [about] this movie is them trying to race against the idea of how to prevent Peter from mutating totally."
So, that could be interesting with the whole Man-Spider thing. If you caught the recently leaked footage, you already know there’s a moment where Peter appears to emerge from a web cocoon.
There’s also speculation that he may develop organic web-shooters. If this story leans fully into body horror territory, six extra arms and a full-blown Man-Spider transformation don’t feel out of the question. And with Mark Ruffalo confirmed to return as Hulk, it’s not hard to imagine that escalating into something wild.
Of course, Peter’s mutation might not be the only major development in play. Campea also doubled down on the idea that Sadie Sink is playing Jean Grey. If true, that opens the door to mutants becoming a central focus of the MCU moving forward.
He explains, "This is gonna be setting up the anti-mutant thing, because Jean Grey is being hunted because she's a mutant...it's pre-Xavier School."
That suggests the MCU isn’t introducing the X-Men as a fully formed team right out of the gate after Avengers: Secret Wars. Instead, mutants may be emerging one by one. We’ve already seen hints of that with characters like Ms. Marvel and Namor.
A pre-Xavier era where fear and government control take center stage feels like a natural evolution, and if Tramell Tillman really is playing the head of the Department of Damage Control, that anti-mutant tension could hit hard.
Behind it all is director Destin Daniel Cretton, who previously helmed Shang-Chi and the Legend of the Ten Rings, working from a script by returning franchise writers Chris McKenna and Erik Sommers.
With Spider-Man: Brand New Day, they’ve got a cast that includes Tom Holland back in the suit alongside Zendaya, Jon Bernthal, Michael Mando, Jacob Batalon, Liza Colón-Zayas, Marvin Jones III, and more. Florence Pugh is also expected to reprise her role as Yelena Belova.
If these details are accurate, this isn’t just another street-level Spider-Man story. It’s body horror mixed with the birth of the MCU’s mutant era, all wrapped inside a desperate attempt to save Peter Parker from becoming something monstrous.
Spider-Man: Brand New Day swings into theaters on July 31, 2026.
