- Quick Answer: Avengers: Doomsday will introduce Robert Downey Jr.’s Doctor Doom as a peak-power antagonist, shifting focus from Reed Richards to the Avengers.
Marvel will take a different approach in introducing Doctor Doom (Robert Downey Jr.) in the highly anticipated Avengers: Doomsday, starting his story in reverse that could be a make-or-break moment for the MCU.
As the first MCU villain to have his origin told this way, it remains to be seen how fans will react to this new strategy.
But as one of Marvel’s ultimate villains, will Doctor Doom’s debut be a hit or miss with viewers?
How Will Doctor Doom be Introduced in Avengers: Doomsday?
Compared to other MCU villains like Loki (Tom Hiddleston), Thanos (Josh Brolin), and Kang (Jonathan Majors), whose stories start from the beginning during their introduction, Doctor Doom debuts at the very climax of his journey.
After his brief appearance in The Fantastic Four: First Steps’ post-credits scene, the new big bad will be next seen as the most terrifying, multiverse-conquering incarnation.
So, how this will happen? Unlike his story in the Marvel Comics, where his evolution follows a more traditional sequence of events where he develops a feud with Reed Richards, becomes Larveria’s dictator, and turns into the Fantastic Four’s main villain, his true identity and motives will be peeled back in layers as Doomsday begins.
So, instead of seeing him slowly rise to power like the usual antagonist story, he will be instantly seen as an enemy of the Avengers instead of an enemy of the Fantastic Four.
With that being said, his traditional origin story may not be told, though Marvel may have other great plans to tell his tale.
How Avengers: Doomsday’s Approach to Doctor Doom’s Story Will Affect Future Fantastic Four Movies?
While Doctor Doom has been a looming presence in Marvel Comics, he has yet to make a significant impact on the cinematic universe.
This is likely why he is being introduced instantly as a multiversal antagonist, rather than being featured in a Fantastic Four movie.
Previous cinematic versions tied him solely to the Fantastic Four, making him a byproduct of Reed Richards’ scientific breakthroughs and a villain of lesser scale.
But with his pivotal role in Doomsday and its follow-up, Avengers: Secret Wars, Doctor Doom is set to become a formidable foe not just for the Fantastic Four, but for all of the MCU’s heroes.
Coupled with Robert Downey Jr. taking on the role, Marvel is clearly building massive hype that fans have been eagerly anticipating.
From a simple antagonist, Doom’s position as an Avengers-level enemy helps establish his “God-Emperor” stature that can carry over into future Fantastic Four movies, potentially exploring his deeper, more authentic history with Reed Richards and his team.
If Marvel manages to execute this approach successfully, the MCU’s version of Doctor Doom could easily become the best cinematic portrayal yet.
Doomsday is slated for release on December 18, 2026, followed by Secret Wars on December 17, 2027.
