Marvel Studios’ Avengers: Doomsday is shaping up to be one of the most ambitious ensemble films in MCU history. Directed by the Russo Brothers, the highly anticipated project is scheduled for release on December 18, 2026, with its direct sequel, Avengers: Secret Wars, set to arrive on December 17, 2027. Furthermore, this timeline highlights Marvel Studios’ careful planning to expand the MCU’s multiverse saga while keeping fans eagerly anticipating each new chapter.
While the official storyline remains under wraps, however, recent reports have sparked major fan excitement by hinting at the arrival of six powerful MCU teams. In particular, these rumored lineups could bring together characters from across the multiverse, thereby creating unexpected alliances and rivalries. Ultimately, if confirmed, this would mark one of the most diverse and ambitious team rosters in MCU history.
Possible MCU Teams in Avengers: Doomsday
According to insider Alex Perez of The Cosmic Circus, the film could feature a multiverse-spanning roster unlike anything seen before in the MCU. Consequently, if these rumors are true, the following teams might unite — or clash — on the big screen. In either case, this potential lineup could dramatically expand the scope of the MCU’s multiverse narrative.
Sam’s Avengers
Specifically, led by Anthony Mackie’s Captain America, this new Avengers lineup is expected to take center stage.
New Avengers (with the “Z”)
A fresh generation of heroes, rumored to include familiar faces alongside brand-new recruits.
Fantastic Four
Marvel’s First Family, including Vanessa Kirby’s Invisible Woman and Pedro Pascal’s Mister Fantastic, may finally join the MCU’s biggest battle.
Team Loki
Meanwhile, with Tom Hiddleston reprising his role, this group could bring unpredictable mischief to the fight.
X-Men
Legendary mutants such as Patrick Stewart’s Professor X and Channing Tatum’s Gambit are reportedly on the roster.
Team Doom
Possibly led by Doctor Doom, although it remains unclear whether this team will feature other villains, Doom variants, or even Doombots. In either case, their involvement could add a dangerous layer to the Avengers’ challenge.
Confirmed and Rumored Cast Across Teams
Notably, the rumored lineup spans decades of Marvel storytelling, effectively merging characters from the Infinity Saga, Multiverse Saga, and upcoming MCU projects.
