David Harbour has revealed that several heroes in Avengers: Doomsday will be getting new gear and suit upgrades when they return to the Marvel Cinematic Universe.

The actor recently reflected on his experience working on the highly anticipated crossover film, which is expected to unite characters from across multiple corners of Marvel's ever-expanding universe. While Harbour was careful not to reveal any major story details, he did offer fans a small tease about what they can expect when familiar heroes return to the screen.

As Marvel continues to keep much of the project under wraps, even the smallest updates from cast members have quickly become talking points among fans eager for clues about the next Avengers event.

One of the biggest questions surrounding Avengers: Doomsday is how Marvel's heroes will evolve following years of interconnected storytelling across films and streaming series. While discussing the upcoming blockbuster, David Harbour hinted that audiences can expect some noticeable visual changes when several familiar characters make their return.

"But each individual character gets new stuff... like you get new gear, pieces of equipment, or whatever it is." the actor said in a recent interview with Variety.

Although Harbour did not elaborate on which heroes will receive new costumes or how extensive the changes might be, updated suits have long been a tradition within the Marvel Cinematic Universe.

Major crossover films often introduce refreshed designs that reflect new alliances, technologies, or stages in a character's journey. Throughout the MCU, costume changes have rarely been purely cosmetic, often signaling a major shift in a hero's role, abilities, or circumstances. That history makes Harbour's brief comment particularly intriguing, as fans begin wondering which characters could be in line for their next big upgrade.

With Avengers: Doomsday set to bring together heroes from multiple Marvel franchises, Harbour's comments have already sparked speculation about which characters could be receiving their next major makeover.

While the costume tease immediately grabbed attention, David Harbour seemed just as excited by the experience of participating in one of Marvel's largest productions to date. The actor spoke about the unique feeling of sharing the screen with characters that audiences have followed for years, describing the production as something special even for the performers involved.

"It's fun for us to be in it and do our bit, but also have a front-row seat to all these characters we've loved for years and watch them do this stuff. It's just a blast." Harbour said to Variety.

Harbour also revealed that he shared scenes with Florence Pugh during production, continuing the relationship between Red Guardian and Yelena Belova that began in Black Widow and developed further through Marvel's more recent projects.

Harbour is expected to reprise his role as Red Guardian in the film, placing him among a massive ensemble cast preparing to face the MCU's next major threat. While Marvel remains highly secretive about the story itself, the project is widely expected to play a crucial role in shaping the future of the franchise and setting the stage for Avengers: Secret Wars.

For now, fans will have to wait for trailers and official footage to get a better look at these upgrades. But if Harbour's comments are any indication, Avengers: Doomsday will not only bring together some of Marvel's biggest heroes—it may also give them a fresh new look in the process.
