Avengers: Doomsday - A Secret Avengers vs. X-Men Film?

At San Diego Comic-Con 2024, Marvel Studios unveiled exciting updates about the future of the Marvel Cinematic Universe (MCU), with a major highlight being the return of Robert Downey, Jr. as Doctor Doom. Doom will play a pivotal role in the climax of the Multiverse Saga, featuring prominently in both 2026's *Avengers: Doomsday* and 2027's *Avengers: Secret Wars*. Additionally, *Kelsey Grammer* will reprise his role as Beast in *Doomsday*, following his cameo in 2023's *The Marvels*. These announcements have sparked speculation about the plot of *Avengers: Doomsday*, with many wondering if it could be an adaptation of the *Avengers vs. X-Men* storyline from the comics.

Could *Avengers: Doomsday* be a secret *Avengers vs. X-Men* film? There's growing evidence to suggest this might be the case. The Avengers and X-Men have a rich history of both collaboration and conflict in the comics. The 2012 *Avengers vs. X-Men* storyline, in particular, saw the teams at odds due to the Phoenix Force's arrival on Earth. The Avengers viewed the Phoenix as a threat, while Cyclops and the X-Men saw it as their salvation. This led to a fierce battle, with unexpected alliances and dramatic shifts in power dynamics.

In the MCU, the Avengers are currently without an official team, and the X-Men have been introduced sparingly, mostly through characters from other universes. However, the post-credits scene in *The Marvels* hints at a connection between the MCU and the Fox X-Men universe, with Monica Rambeau seemingly trapped there. This could set the stage for an Incursion between Earth-616 and Earth-10005, mirroring the conflict in the 2015 *Secret Wars* comic where the Avengers and Ultimates fought over the survival of their respective universes.

Doctor Doom's role in *Doomsday* adds another layer of intrigue. Known for his ambition and manipulation, Doom could exploit the conflict between the Avengers and X-Men to further his own goals. His involvement in the multiverse's collapse, as seen in the comics, suggests he might be orchestrating events behind the scenes, much like Zemo in *Captain America: Civil War*.

*Avengers: Doomsday* is poised to lead into *Avengers: Secret Wars*, likely ending with the destruction of the multiverse and the creation of Battleworld, a patchwork reality ruled by Doom. This setup would pave the way for a grand finale in *Secret Wars*, where heroes from various universes unite to restore the multiverse and overthrow Doom.

With these developments, the MCU is gearing up for a thrilling and interconnected narrative arc that promises to bring beloved characters together in new and unexpected ways.
