With Avengers: Doomsday just a month away, Marvel fans have been buzzing with theories about the film's plot, especially regarding the return of Robert Downey Jr. as Doctor Doom. Now, Marvel Studios president Kevin Feige has stepped in to clear the air, putting an end to one of the biggest fan speculations.
In a recent interview with Empire magazine, Feige addressed the widespread theory that Doctor Doom is actually a variant of Tony Stark, aka Iron Man. He firmly denied this, stating, "Is Steve Rogers a Johnny Storm variant? People wondered, 'Is Doom just a variant of another character? Is this just a shortcut to bringing back another character?' The answer is no. He's Victor Von Doom."
This clarification comes after Marvel announced in 2024 that the fifth Avengers film would pivot from Kang the Conqueror to Doctor Doom as the main antagonist, following Jonathan Majors' legal issues. The title was changed from The Kang Dynasty to Doomsday, and Downey Jr. was cast as the iconic Fantastic Four villain, marking his return to the MCU in a new role.
Feige's comparison to Chris Evans, who played both Steve Rogers and Johnny Storm, reinforces that actors can portray multiple distinct characters within the Marvel universe without them being connected. This should put to rest any lingering hopes that Downey Jr.'s casting hints at a secret Iron Man comeback.
While fans have yet to see Doctor Doom's full power on screen, early glimpses have already showcased his formidable abilities. In the post-credit scenes of Avengers: Endgame Encore and VisionQuest, Doom was seen traversing the multiverse, capturing heroes like Hulk and Wanda Maximoff, and even reviving the Scarlet Witch. The Avengers: Doomsday trailer also showed him going toe-to-toe with Thor and raising an army of giants.
Co-director Joe Russo also weighed in on Doom's menace, describing him as a "Gothic character" who is "worth being scared of." He added, "Doom is a very powerful character with some very dark magic, and he's not above selling his soul to get what he wants."
As the MCU's Multiverse Saga continues, Avengers: Doomsday promises to be a pivotal chapter. With Feige's confirmation, fans can now look forward to seeing Downey Jr. bring a completely new villain to life, distinct from his beloved Iron Man persona.
