The Marvel Cinematic Universe is gearing up for a major reunion with Avengers: Doomsday, marking the return of the Avengers after six years since Avengers: Endgame. Directed by Anthony and Joe Russo, this upcoming film promises to deliver new surprises, including a fresh storyline and a star-studded ensemble cast.
Initially announced at San Diego Comic-Con in July 2022, Avengers: Doomsday has undergone several changes since its inception. The film was originally set to feature an alternate-timeline version of Kang the Conqueror, played by Jonathan Majors. However, after Majors was found guilty of assault and harassment in December 2023, Marvel quickly reworked the script and shifted the focus of the film.

In 2024, more details emerged about the plot, with the biggest revelation being the return of Robert Downey Jr. to the MCU—this time as the villain, Doctor Doom. Downey’s return, as a new and powerful antagonist, is sure to be a major talking point for fans as they anticipate his showdown with the Avengers.
Although the official plot of Avengers: Doomsday has yet to be fully disclosed, a look at the 2011 comic Ultimate Comics: Doomsday offers some potential hints. The storyline in the comics sees the Fantastic Four team up with various Marvel superheroes to confront a mysterious villain threatening to destroy their timeline. It’s later revealed that the villain is actually a familiar hero who has turned evil in the multiverse. This intriguing twist could play a key role in the film’s narrative.
