Rumored Addition of Two Iconic X-Men Characters to Avengers: Doomsday

Overview of Avengers: Doomsday

Robert Downey Jr. takes on the role of Doctor Doom, the central villain in Avengers: Doomsday, reuniting various MCU heroes.
Recent rumors suggest the inclusion of popular X-Men characters, including X-23 and Beast, in both Doomsday and the upcoming Secret Wars film.
Marvel Studios appears poised to weave mutants into the MCU narrative, particularly through these two forthcoming Avengers installments.

The upcoming Avengers: Doomsday is set to feature an array of beloved characters from the Marvel Cinematic Universe (MCU), and there’s buzz about two well-known X-Men actors returning to their iconic roles.

Details regarding the actual plot of Avengers: Doomsday remain sparse at this time, but what is confirmed is that Robert Downey Jr. will portray Doctor Doom, one of Marvel’s most formidable villains. True to form, audiences can anticipate a coalition of heroes from previous installments rallying together against the threats posed by Doctor Doom and his allies. Since the events of Avengers: Endgame, a host of new characters have already made their debut within the franchise, providing Marvel Studios with a vast array of superheroes to showcase. Recent reports speculate that two beloved X-Men characters are among those expected to make an appearance.

Respected scooper MyTimeToShineHello has indicated that Dafne Keen will reprise her role as X-23 (Laura Kinney) for both Avengers: Doomsday and Secret Wars. Adding to the excitement, reliable insider Alex Perez from The Cosmic Circus confirmed the return of Kelsey Grammer as Beast (Dr. Hank McCoy). However, specifics about whether these characters will appear in Doomsday, Secret Wars, or both have yet to be clarified, leaving fans eager for more information about the extent of their roles in the upcoming films.

The news of Keen’s and Grammer’s returns for Avengers: Doomsday and Secret Wars is both thrilling and somewhat expected. Although these portrayals originated from Fox’s X-Men franchise, both characters were reintroduced to the MCU during the Multiverse saga. Keen first appeared as X-23 alongside Hugh Jackman in the critically acclaimed film Logan in 2017, and she later reprised her character in Deadpool and Wolverine. After being exiled into the Void, X-23 is seen celebrating with Wolverine and Deadpool in a pivotal scene. Meanwhile, Grammer’s Beast made a brief return in a post-credits scene from The Marvels, where he interacts with Monica Rambeau in an alternate reality.

While Beast’s cameo in The Marvels has yet to lead to any significant developments, speculation surrounding the casting for Avengers: Doomsday could provide a long-awaited payoff. Both Keen and Grammer have openly expressed a desire to return, and Grammer even confirmed he has initiated discussions with Marvel Studios regarding reprising his role. Consequently, these emerging rumors, though yet unverified by official channels, carry a tangible sense of credibility.

The X-Men’s anticipated involvement in the next two Avengers films indicates that both X-23 and Beast will likely be joined by additional mutants. Marvel Studios head Kevin Feige has hinted that Avengers: Secret Wars will pave the way for a new era of X-Men, generating excitement among fans concerning how these characters will integrate into the broader Multiverse saga. A prevalent theory suggests that Avengers: Secret Wars could reboot the MCU, establishing a continuity where mutants have always existed within the franchise. If this theory holds merit, the inclusion of X-Men characters in both Doomsday and Secret Wars could substantiate its foundations.

Avengers: Doomsday is slated for a theatrical release on May 1, 2026.
