Avengers: Doomsday is gaining momentum as new rumors tease multiversal travel and surprising alliances. Reports suggest a key Thunderbolts member will accompany Captain America’s team to another universe, sparking talk of a larger crossover. With returning heroes and familiar faces from across the MCU, early details are already generating buzz.
Yelena and Sam’s Avengers team could go to a new universe in Avengers: Doomsday
A new rumor shared by insider Daniel Richtman suggests that Yelena Belova (Florence Pugh) will accompany Sam Wilson’s (Anthony Mackie) Avengers team in Avengers: Doomsday during a mission to another universe.
Richtman clarified on social media that Belova is “not part of Sam’s team” but will travel with them during their multiversal journey. This clarification follows earlier speculation from a May 2025 report that placed Yelena on Captain America’s roster.
Although the full script for Avengers: Doomsday reportedly remains incomplete, the new development hints at a crossover between the Thunderbolts and Avengers. Richtman’s update prompts speculation about whether Sam’s team will include other Thunderbolts members. These could include U.S. Agent (Wyatt Russell), Ghost (Hannah John-Kamen), or Red Guardian (David Harbour). Leaving them behind may not fit the narrative.
Marvel Studios President Kevin Feige previously hinted that the Avengers will appear at the Fantastic Four’s Baxter Building on Earth-828. This suggests that Sam’s team, possibly joined by Yelena and other Thunderbolts, will travel to that alternate universe as part of the multiverse storyline.
The cast list includes characters from both the mainline MCU and Fox’s X-Men universe, including Loki (Tom Hiddleston), Sentry (Lewis Pullman), Magneto (Ian McKellen), Sue Storm (Vanessa Kirby), and Doctor Doom (Robert Downey Jr). Rebecca Romijn, who plays Mystique, confirmed in an interview with The Hollywood Reporter that the script has not yet been finalized and said, “The script hasn’t — they haven’t finished writing it… They keep everything very close to the vest.”
Marvel Studios plans to release Avengers: Doomsday on December 18, 2026. Anthony and Joe Russo will direct the film, marking their return to the MCU after directing Avengers: Endgame.
