Every Major ‘Spider-Man: Brand New Day’ and ‘Avengers: Doomsday’ Leak So Far, From Trailer Footage to Toy Reveals

Marvel and Sony have been fighting a losing battle against the leak machine this summer. Between blurry trailer footage circulating on social media, audio drops that fans have pulled apart frame by frame, and a merchandise rollout that keeps spilling major plot points, the most anticipated Spider-Man film in years is losing its secrets at a rapid pace. For anyone trying to stay ahead of the curve on ‘Spider-Man: Brand New Day‘ and its towering companion piece ‘Avengers: Doomsday’, here is a breakdown of everything that has surfaced so far.

The two films represent Marvel’s biggest one-two punch in years. ‘Spider-Man: Brand New Day’ picks up four years after the events of ‘No Way Home’, with Peter Parker living alone in a New York City that has no memory of who he is, having devoted himself entirely to protecting the city as Spider-Man. Directed by Destin Daniel Cretton, who previously helmed ‘Shang-Chi and the Legend of the Ten Rings’, filming on the project wrapped on December 19, 2025.

The Leaked Trailer Footage and What It Reveals

An official-looking full trailer for ‘Spider-Man: Brand New Day’ leaked online on June 7, 2026, with a description that confirms the film opens in a prison setting where Spider-Man faces off against members of The Hand in a tense standoff.

The Hand, the deadly ninja organization first introduced in the MCU through Netflix series like ‘Daredevil’ and ‘The Defenders’, were already visible in the Easter egg-laden first trailer released back in March, alongside Tarantula and a confirmed line of dialogue from Scorpion, played by Michael Mando.

According to the detailed description circulating online, a pivotal scene features Peter Parker asking Bruce Banner whether he found a way to suppress mutating DNA, with Banner warning that if Peter ever sees him without his inhibitor, he should run. From there, the leaked trailer description depicts Peter struggling with his new powers, swinging at extreme speeds, losing control, crashing into objects, and even landing at a wedding.

The footage becomes increasingly intense from that point, showing a tank running over Spider-Man, a massive explosion on an island that impacts the city, and a sequence where everyone appears frozen except for Spider-Man and the Punisher. The leaked second trailer also reportedly features Marisa Tomei providing narration, while the money-shot battle between Spider-Man and The Hand has been shifted from the sky to inside a prison.

The Sadie Sink Jean Grey Theory Is Looking More Like Fact

No element of ‘Brand New Day’ has generated more feverish discussion than Sadie Sink’s undisclosed role. Sink joined the cast in March 2025 in a role Marvel has refused to officially name, but multiple scoopers have pointed toward the ‘Stranger Things’ star as the frontrunner to play Jean Grey.

The leaked audio confirms that the lead villain uses mind control and takes control of Bruce Banner, transforming him into a rampaging Hulk capable of going toe-to-toe with Spider-Man, while also using a member of the public to threaten MJ.

The leaked description places Jean Grey at the center of the action, with the character shown jumping from mind to mind while hunting for Spider-Man, rather than appearing in a brief cameo or post-credits scene.

Scooper Cryptic HD QUALITY has reported that Sink’s character receives what they described as the “First Steps Sue treatment,” with a new visual flair to her powers that involves heavier VFX work compared to previous portrayals of the character. Insider Daniel Richtman has further claimed that Sink’s character shares a close relationship with Jon Bernthal’s Punisher, and will demonstrate her mind-control abilities during the film’s tank sequence.

What the Toy Leaks Are Quietly Confirming

Merchandise has been the most consistent source of spoiler fuel for ‘Brand New Day’, and the rollout has been remarkably revealing. Following Sony’s CinemaCon panel, the first wave of merchandise officially confirmed the presence of the Hulk, with toys identifying this version of the character as “Savage Hulk”, and LEGO sets including a minifigure of Tombstone, who remains a rumored major antagonist.

Hasbro revealed a Savage Smash Hulk figure at CinemaCon 2026 with two “angry” modes of play, alongside a Power-Charge Spider-Man figure standing at 14.5 inches that features Anti-Gamma Mode, Web-Tracking Mode, and Power-Web Mode, each with unique lights and sound effects suggesting the film leans heavily into the Hulk confrontation.

Newer product listings have further teased “uncontrollable transformations” for both Spider-Man and Hulk, while a talking mask toy has unveiled several potential lines of dialogue from Peter, including the phrase “my spider-tingle’s going crazy,” suggesting the film rebrands the classic Spider-Sense. A more recent bag clip series has revealed yet another variant of the Hulk, further fueling the theory that Sadie Sink’s character uses her abilities to alter Banner’s mind, forcing Spider-Man to team up with The Punisher to stop him.

The ‘Avengers: Doomsday’ Spider-Man Connection

While ‘Brand New Day’ is stealing the leak spotlight, ‘Avengers: Doomsday’ has its own web-slinging bombshells. Insider account MyTimeToShineHello posted on X that Tobey Maguire is set to appear in ‘Avengers: Doomsday’, a claim that followed an earlier report from Daniel Richtman suggesting Maguire was using a CGI-enhanced costume during filming and would sport a new suit design.

According to multiple plot leaks, ‘Doomsday’ will open with a sequence set in Sam Raimi’s Spider-Man universe, where Tobey Maguire’s Peter Parker desperately attempts to prevent an incursion but ultimately fails, becoming the sole survivor of his world before being whisked away by a portal.

Leaks describe Doctor Doom as functioning as a “wolf in sheep’s clothing” who unites with Earth’s Mightiest Heroes under seemingly noble intentions, while concealing a deeper revenge quest against the Multiverse itself.

Industry insider Alex Perez of The Cosmic Circus has noted that ‘Spider-Man: Brand New Day’ is expected to directly set up ‘Avengers: Secret Wars’, placing it in an important narrative position for the MCU’s long-term future. ‘Avengers: Doomsday‘ is currently scheduled to arrive in theaters on December 18, 2026.

The Bigger Picture for Peter Parker’s New Era

Peter’s new suit in ‘Brand New Day’ has been confirmed as entirely hand-made, with no Stark technology, no AI assistant, and no heads-up display, with director Cretton reportedly annotating his script with the note that all of Peter’s tech must be things he created himself.

The full confirmed cast includes Tom Holland, Zendaya, Jacob Batalon, Sadie Sink, Jon Bernthal, Mark Ruffalo, Florence Pugh as Yelena Belova, Michael Mando as Scorpion, and Marvin Jones III as Tombstone, alongside Liza Colón-Zayas and Tramell Tillman in undisclosed roles.

With a villain lineup that stretches to include Scorpion, Boomerang, Tarantula, The Hand, Tombstone, and Sadie Sink’s mystery character, ‘Brand New Day’ is shaping up to feature one of the largest collections of antagonists in any Spider-Man film to date.

The sheer scale of what these leaks are suggesting has the MCU fandom in full frenzy mode weeks before any official release, and with an official trailer rumored for June 17, the wait for confirmation may be short. If Sadie Sink is truly playing a villainous Jean Grey with the power to turn the Hulk against Spider-Man, does that feel like the MCU X-Men debut you have been hoping for, or is it too much for a solo Spider-Man film to carry?
