Nerdrotic says Brie Larson won’t be back as Captain Marvel in Avengers: Doomsday. Recall how the YouTuber also just said Jon Bernthal’s Punisher would be in Spider-Man: Brand New Day.
The popular YouTuber tweeted, “There is no Brie Larson Captain Marvel in Avengers: Doomsday,” adding “Nope” when asked if Ironheart was in it.

He also said, “Well Pedro is in it for sure. I assume Tessa Thompson will be in it, or Secret Wars for sure.”

The next Avengers movie, Avengers: Doomsday, arrives on December 18, 2026, launching the final phase before Avengers: Secret Wars. Marvel has officially confirmed 27 cast members, with another 33 rumored to appear — including Brie Larson. However, according to Nerdrotic, Captain Marvel won’t be part of the film. That’s a significant change for a studio that once positioned Larson as the face of its future after Endgame, but it’s clear that direction has shifted.
Brie Larson Sparks Rumors With New Look
Fans have noticed Brie Larson’s new short blonde hairstyle that looks a lot like her Avengers: Endgame haircut. The actress showed off the look on social media after shaving her head earlier this year for a play, fueling speculation she could be returning as Captain Marvel in one of the upcoming Avengers films.
Nerdrotic’s claim, however, suggests otherwise. If true, it would mean Larson’s Captain Marvel is being sidelined entirely after years of inconsistent appearances across the franchise.
Ironheart and Marvel’s Streaming Struggles
Nerdrotic also shot down any chance of Ironheart appearing in Avengers: Doomsday. The Disney+ series starring Riri Williams has been canceled after poor reception and viewership.
The failure of Ironheart is part of a larger problem for Marvel’s Disney+ shows, which have seen declining viewership and critical reception as budgets balloon and audience interest fades.
Disney has now switched gears and is going with less content and cheaper budgets, as evident by Daredevil: Born Again.
The Marvels Was A Massive Flop
Brie Larson’s last MCU outing, The Marvels, was the worst-performing movie in Marvel Studios history. The film made just $206 million worldwide on a $270 million budget, far below expectations for a mainline Marvel release.
The film also starred Iman Vellani as Ms. Marvel and Teyonah Parris as Monica Rambeau, but despite the crossover setup, it failed to draw audiences.
Its weak box office and lukewarm reviews likely played a role in Marvel deciding to scale back on characters tied to that movie.
Disney Admits It Lost Male Fans
Adding to the picture, Disney recently acknowledged that Marvel and Star Wars have driven away male viewers. Internal reports show the company is now trying to win them back after years of audience decline across those brands.
The admission explains a lot about recent creative shifts and cast changes. Marvel’s next wave seems aimed at bringing back the core male audience that powered its success through Endgame.
Marvel’s Big Reset
Between The Marvels bombing, Ironheart flopping, and Brie Larson’s rumored absence from Avengers: Doomsday, Marvel appears to be pressing the reset button.
It’s no secret that the MCU has struggled to recapture the excitement of its earlier phases. With Avengers: Doomsday and Secret Wars on the horizon, the studio could be reshaping its roster around fan-favorite characters and actors who can reignite the franchise’s appeal.
Whether Brie Larson’s Captain Marvel will return down the line remains to be seen—but for now, it looks like her cosmic run may have finally come to an end.
