Marvel has made it very clear who will be the villain ofAvengers: Doomsday, Robert Downey Jr.s Doctor Doom. But who are the Avengers of thisAvengers sequel? The Marvel Cinematic Universe movies and shows of late have given us almost no clue who will be the next iteration of Earths Mightiest Heroes.Today the company decided to make things a little clearer, revealing on social media and YouTube the cast members who will appear inDoomsday one by one. So far the confirmedstars of the film are Chris Hemsworth as Thor, Vanessa Kirby as the new Invisible Woman from the upcomingThe Fantastic Four: First Steps, Anthony Mackie as Captain America, Sebastian Stan as Winter Soldier, Letitia Wright as theBlack Panther, Shuri, Paul Rudd as Ant-Man, Wyatt Russell as U.S. Agent, Tenoch Huerta Mejia as Namor, Ebon Moss-Bachrach as the Thing, Simu Liu as Shang-Chi, Florence Pugh as Black Widow, Kelsey Grammer (presumably) as the Beast, Lewis Pullman as the Sentry, Danny Ramirez as the Falcon, Joseph Quinn as the Human Torch, David Harbour as Red Guardian, and Winston Duke as MBaku.(Note: This list will be updated as more names are announced.)READ MORE: The Best Marvel Movies Not Made By Marvel StudiosMostof these names are not especially surprising.Captain America: Brave New Worldinvolved Mackies Sam Wilson debating whether to restart the Avengers; given this movie is calledAvengers: Doomsday, you had to assume he would be involved. Hemsworth is one of the most senior members of the MCU whos character hasnt been been killed or retired (yet). Wright became the new Black Panther inBlack Panther: Wakanda Forever.Stan appeared in the last two Avengers films and will soon appear inThunderbolts.Rudds Ant-Man managed to survive his battle with Kang inQuantumania. (Also: Very nice touch giving him a smaller directors chair.) Russell is another member of the Thunderbolts, and a former Captain America himself. Kirby, Moss-Bachrach, and Quinn arepart of the new Fantastic Four, and this is a movie about Doctor Doom, the FFs top villain. One assumes all four members of that team will be announced forDoomsdaybefore all is said and done.One name thatisa bit of a surprise so far is Tenoch Huerta Mejia as Namor, just because he was depicted as more of a villain than a potential Avenger in his one previous MCU appearance,Black Panther: Wakanda Forever. But if you know Marvel Comics history, you know that Namor does have a history with the team (as both an adversary and a member) and with Doctor Doom as well. Plus, if the film will involve a massivethreat to the entire planet, the king of the oceans is the sort of guy whod get involved in that sort of thing.As for Simu Liu, Shang-Chi and the Legend of the Ten Ringsdidvery well in theaters despite opening during the middle of the pandemic. He still hasnt gotten a sequel, though, and his movie ended on a cliffhanger involving some sort of interplanetary beacon that could be continued inAvengers: Doomsday.(It also felt like one of the reasons they gave the MCUs Shang-Chi super powers when the Marvel Comics version of the character is just an elite martial artist was so that the character could become a member of a heavy-hitter group like the Avengers.)Pughs Black Widow has been one of the busiest Marvel heroes in recent years, appearing inBlack Widow,Hawkeye, and the upcomingThunderbolts.The biggest shock (so far) was the announcement that Kelsey Grammer was joining the film, presumably as Beast, the X-Man hero that he previously played in 2006sX-Men: The Last Stand, and then in a cameo role in 2023sThe Marvels.Grammers involvement is the first confirmation that the X-Men (or at least some mutant characters) will be a part of the film.Avengers: Doomsdayis scheduled to open in theaters on May 1, 2026. The film is now officially in production.
