Avengers: Doomsdayhas added an X-Men franchise star. TheMarvel Cinematic Universeis getting ready for one of its biggest movies ever. With the Multiverse Saga getting into its final phase, the franchise is inching closer to theMCU’s first X-Men movie. However, mutants are expected to appear in the final films of the ongoing saga, which has been revealed by Marvel Studios President Kevin Feige. Now, there has come solid confirmation of that, asAvengers: Doomsday’s castwill include at least one star from Fox’s X-Men movies.
DuringMarvel Studios' livestream to announceAvengers: Doomsday’s cast,it was revealed that Beast actor Kelsey Grammer will appear in the MCU movie.

Grammer first played Beastin X-Men: The Last Standbefore making a cameo inX-Men: Days of Future Past. Recently, he joined the MCU inThe Marvels' post-credits scene. The sequence revealed that Monica Rambeau landed in a universe that had a version of the X-Men. Grammer’s Beast and Lashana Lynch’s Binary greeted her there, with Beast commenting on how he would talk about her with Charles Xavier. Interestingly, both Lynch and Teyonah Parris are absent fromAvengers: Doomsday’s full cast list.
What Kelsey Grammer’s Avengers: Doomsday Casting Means
The MCU Is About To Use The X-Men In A Big Way
With Grammer confirmed forAvengers: Doomsday, it seems like at least one of the Earths that will come into an incursion with the MCU’s Earth-616 has become known.The X-Men are set to play a role in the next Avengers moviebefore Marvel Studios' version of the team debuts. While Beast and Binary showed up inThe Marvels, they were clearly in a version of the X-Men mansion, and Grammer’s character mentioned that he was going to talk to Charles Xavier.Avengers: Doomsdaycould show a full universe of variants of Fox’s X-Men characters, if not their original selves.
After The Avengers: Doomsday Directors' Comments About Iron Man’s Death Connecting To Doctor Doom, These 10 MCU Characters Absolutely Need To Return
Iron Man’s death will seemingly play a role in Doctor Doom’s debut, and that means Avengers: Doomsday should bring back some important MCU characters.
Doctor Strange in the Multiverse of Madnessintroduced the concept of incursions, which are the events that happen when multiple Earths collide, destroying one or more of them. The MCU has already shown a few universes, andThe Marvels' X-Men Earth, the Illuminati’s Earth-838, and more could come clashing with Earth-616, leading to the new Avengers fighting the X-Men and other heroes for survival. Another possible route the movie takes is that Grammer’s Beast and his X-Men team assist the Avengers as they fight Doctor Doom, which could then also turn into a fight between the teams in the end.

Our Take On Kelsey Grammer’s Avengers: Doomsday Casting
The MCU’s Next Avengers Movie Just Got Even More Exciting
I’m excited about Grammer’s confirmation. I always wanted to see more of his Beast afterX-Men: The Last Standandthe MCU made his design even better with great CGI inThe Marvels. With Beast and the universe he is from set to be inAvengers: Doomsday, I think we can now finally see those rumors about the Avengers fighting the X-Men come true. The incursions are about to throw the multiverse into disarray, and everyone will want their Earth to survive. I also like how it showsThe Marvels' importance, as it leads directly intoAvengers: Doomsday.
