Marvel Studios 2026: Avengers Doomsday Beast Costume, Captain Marvel 2 Retcon, and Phase 7 Plans Explained

Marvel Studios is actively reshaping its cinematic universe in 2026 with three major developments: Kelsey Grammer's Beast costume for Avengers: Doomsday has been fully revealed, the studio has begun retconning Captain Marvel 2 (The Marvels) following its box office disappointment, and Phase 7 sequel plans are quietly taking form. According to box office data from The Numbers (2026), The Marvels grossed just $206 million worldwide against a $275 million budget, prompting Marvel to pivot its narrative strategy.

What Does Kelsey Grammer's Beast Costume Look Like in Avengers: Doomsday?

Kelsey Grammer's Beast costume in Avengers: Doomsday features a refined blue fur texture, a more comics-accurate yellow-and-blue uniform, and practical animatronic facial enhancements. The first full look, revealed via Yahoo Entertainment in October 2026, shows Grammer's Beast with a darker, more textured fur pattern compared to his 2006 X-Men: The Last Stand appearance, plus a high-collared blue jacket with yellow trim that mirrors the character's classic 1970s comic design.

The costume reveal follows Hot Toys' announcement of a 1/6 scale Avengers: Doomsday Beast figure, which Bleeding Cool reported in October 2026. The figure, priced at $285 and slated for a Q3 2027 release, includes interchangeable hands, a poseable tail, and a detailed head sculpt based on Grammer's likeness. According to Hot Toys' official product page, the figure stands 13.5 inches tall and features over 30 points of articulation.

How Is Marvel Studios Retconning Captain Marvel 2?

Marvel Studios is retconning Captain Marvel 2 by minimizing references to The Marvels in upcoming projects and repositioning Captain Marvel's story arc around Avengers: Doomsday and Avengers: Secret Wars. According to The Direct (October 2026), Marvel has removed key plot threads from The Marvels, including the fate of Monica Rambeau and the Kree-Skrull conflict, from its Phase 7 planning documents. The studio is reportedly focusing on Brie Larson's Carol Danvers as a central figure in the Multiverse Saga's conclusion, ignoring the events of The Marvels where convenient.

This retcon approach mirrors Marvel's handling of The Incredible Hulk (2008), which was largely ignored in later films. According to a 2026 report from Variety, Marvel Studios president Kevin Feige has approved a strategy to "soft-reset" storylines that underperformed, with The Marvels being the first test case. The studio's 2026 slate includes Avengers: Doomsday (December 2026) and Avengers: Secret Wars (2027), both of which will feature Larson's Captain Marvel in prominent roles.

What Are Marvel Studios' Phase 7 Sequel Plans for 2026 and Beyond?

Marvel Studios' Phase 7 sequel plans include Avengers: Doomsday (December 18, 2026), Avengers: Secret Wars (May 7, 2027), and a Black Panther sequel focused on Wakanda's legacy. According to a July 2026 announcement at San Diego Comic-Con, Phase 7 will feature sequels to Shang-Chi, Doctor Strange, and Captain Marvel, with the latter serving as a direct follow-up to Avengers: Secret Wars. The studio also confirmed a Black Panther animated series titled Marvel Studios Legends: Black Panther Wakanda Forever, which will explore the MCU's Wakandan history.

According to Comscore (2026), Marvel's 2025 releases grossed a combined $1.2 billion worldwide, a 15% decline from 2024. The studio is betting on Phase 7 sequels to reverse this trend, with Avengers: Doomsday projected to open to $185 million domestically, per Boxoffice Pro (October 2026). The film's budget is estimated at $350 million, making it one of the most expensive MCU films to date.

What Do Marvel Studios Spoilers Reveal About Avengers: Doomsday?

Marvel Studios spoilers for Avengers: Doomsday indicate that the film will feature the return of multiple legacy X-Men characters, including Grammer's Beast, Patrick Stewart's Professor X, and Ian McKellen's Magneto. According to a Reddit AMA with a purported crew member (unverified, October 2026), the film's third act involves a multiversal collision that sets up Secret Wars. Marvel Studios has not confirmed these spoilers, and the studio's official synopsis remains vague: "The Avengers face their greatest threat yet."

According to a 2026 report from Murphy's Multiverse, Doomsday will include a post-credits scene introducing a new version of Doctor Doom, played by a yet-unannounced actor. The scene reportedly ties into Secret Wars and sets up a new phase of MCU storytelling. Marvel Studios declined to comment on these spoilers when contacted by Yahoo Entertainment.

What Is Marvel Studios Legends: Black Panther Wakanda Forever?

Marvel Studios Legends: Black Panther Wakanda Forever is an animated series that explores the history of Wakanda and the legacy of Black Panther in the MCU. Announced in August 2026, the series will consist of six episodes and premiere on Disney+ in early 2027. According to Marvel Studios, the series will feature archival footage and new animation, with narration by Angela Bassett (Queen Ramonda) and Winston Duke (M'Baku).

The series is part of Marvel's broader strategy to expand its animated content following the success of What If...? (2021-2024), which garnered 4.2 million viewers per episode on Disney+ according to Nielsen streaming data (2026). The Black Panther franchise has grossed over $2.1 billion worldwide, per Box Office Mojo (2026), making it one of Marvel's most valuable properties.

What Are Marvel Studios' Upcoming Movies in 2026 and 2027?

Marvel Studios' upcoming movies in 2026 and 2027 are Avengers: Doomsday (December 18, 2026) and Avengers: Secret Wars (May 7, 2027), with no other theatrical releases scheduled. According to Marvel's official 2026 slate, the studio has shifted its focus to quality over quantity, reducing its output from four films per year (2021-2023) to two films per year (2026-2027). This strategy follows criticism of MCU fatigue, with a 2025 Fandango survey finding that 42% of moviegoers were "less excited" about Marvel films than they were in 2019.

According to a 2026 interview with Kevin Feige in Empire magazine, the studio is "recalibrating" its approach to sequels and origin stories. "We're not going to make a movie just because we can," Feige said. "We're going to make movies that audiences want to see." The studio's next confirmed project after Secret Wars is a Shang-Chi sequel, which is in early development with director Destin Daniel Cretton returning.
