AVENGERS: DOOMSDAY - Doctor Doom's Backstory & His Feud with Steve Rogers Explained! [MCU Rumors] (2026)

The buzz surrounding Avengers: Doomsday has intensified this long Martin Luther King Jr. weekend, with new rumors surfacing that delve deeper into the backstory of Doctor Doom and his connection to Chris Evans' character, Steve Rogers.

It’s hard to believe that nearly a decade has passed since Marvel Studios brought Captain America: Civil War to the big screen. Most fans will remember the intense debates sparked by the marketing campaign, which pitted #TeamCap against #TeamIronMan, symbolizing the clash between Chris Evans and Robert Downey Jr.

Now, as we look forward to the release of Avengers: Doomsday in December, the Russo Brothers are stepping back into the Marvel Cinematic Universe (MCU) to direct this much-anticipated film. It seems we might witness another face-off between Evans and Downey, reigniting the rivalry that fans are eager to see unfold once more.

Recent discussions have pointed to a storyline where Doctor Doom is on a mission to target Steve Rogers, potentially pulling the former Captain America away from the peaceful resolution he achieved at the conclusion of Avengers: Endgame. As you might recall, to find tranquility with Peggy Carter, Steve had to create a branching timeline, which raises some fascinating implications.

Fans who followed the Loki series will understand that Steve's time-traveling actions were not without their repercussions for the Multiverse.

According to a fresh rumor shared by @MyTimeToShineH, it appears that Victor Von Doom has experienced significant loss, as his wife and son tragically died in an accident. Furthermore, Doom himself sustained severe injuries, leaving him physically scarred. The rumor suggests that he traced the cause of this accident back to Steve Rogers’ time travel, leading Doom to seek vengeance for his family’s demise.

However, not everyone may be pleased with the idea of Captain America being held accountable in place of Mister Fantastic for Doom’s disfigurement. This narrative twist could lead to some divisive opinions among fans, especially since there are whispers that Victor might be manipulating the truth about his past to garner sympathy from the heroes of the Multiverse, using their compassion to serve his own agenda.

Adding to the intrigue, despite earlier speculation, there was no fifth teaser for Avengers: Doomsday shown during the recent Avatar: Fire and Ash screening this past weekend. Fans can look forward to earlier sneak peeks while anticipating a full trailer release during next month’s Super Bowl event.

Avengers: Doomsday boasts an impressive cast that includes Chris Evans, Chris Hemsworth, Anthony Mackie, Winston Duke, Tom Hiddleston, Sebastian Stan, Letitia Wright, Paul Rudd, and Robert Downey Jr. Several newcomers to the Avengers franchise, such as Wyatt Russell, Simu Liu, Tenoch Huerta Mejia, Mabel Cadena, Florence Pugh, Danny Ramirez, David Harbour, Hannah John-Kamen, Lewis Pullman, and India Rose Hemsworth, will also make their debuts.

In addition, stars from the Fantastic Four and X-Men franchises—including Pedro Pascal, Vanessa Kirby, Ebon Moss-Bachrach, Joseph Quinn, Kelsey Grammer, Patrick Stewart, Ian McKellen, Alan Cumming, Rebecca Romijn, and James Marsden—are set to join the lineup. Channing Tatum is expected to reprise his role from the Deadpool and Wolverine series, while Ryan Reynolds and Hayley Atwell are also rumored to appear in Avengers: Doomsday.

The Russo Brothers will direct this film, working from a screenplay by Stephen McFeely, with whom they have previously collaborated on both the Avengers and Captain America series. Notably, Michael Waldron, known for his work on Loki and Doctor Strange in the Multiverse of Madness, is also contributing to the script.

Mark your calendars: Avengers: Doomsday is slated for release on December 18, while Avengers: Secret Wars is set to follow on December 17, 2027.
