The announcement regarding Robert Downey Jr.’s return to the Marvel Cinematic Universe (MCU) as Doctor Doom in Avengers: Doomsday sparked a significant amount of excitement and mixed reactions among fans. Recently, developments indicate that his adaptation of this iconic Marvel antagonist might make an appearance ahead of the film’s release.

During this year’s San Diego Comic-Con, Marvel Studios made waves with their Hall H panel by revealing Robert Downey Jr.’s unexpected comeback to the MCU. This startling news took fans by surprise, especially when producers Kevin Feige and directors Anthony and Joe Russo disclosed that the actor, famous for his role as Tony Stark, would now embody one of the most formidable villains, Victor Von Doom, commonly known as Doctor Doom.

Initially, it was presumed that Downey Jr. would first appear as Doctor Doom in Avengers: Doomsday. However, reputable industry insider @MyTimeToShineH on X has suggested that audiences may witness his portrayal of Victor Von Doom in The Fantastic Four: First Steps, which is set to premiere prior to Doomsday. This would establish a connection between Downey Jr.’s character and the MCU’s version of Marvel’s First Family ahead of the Avengers film, aiding in their introductions within the cinematic universe.

If this speculation holds true, it aligns perfectly with other circulating rumors. For instance, reports indicate that Downey Jr.’s take on Doctor Doom is expected to emerge from the same alternate universe as the Fantastic Four—Reed Richards, Sue Storm, Johnny Storm, and Ben Grimm. Should this information be accurate, it would create an intriguing narrative link.

Additionally, there are claims suggesting that this iteration of Doctor Doom will present a more empathetic character. Fans online have hypothesized that this portrayal may draw inspiration from the 2015 comic series Secret Wars, where Victor Von Doom plays a pivotal role. In this storyline, heroes and villains clash on Battleworld, a planet forged by Doctor Doom amidst the collision of multiple universes.

The upcoming film, The Fantastic Four: First Steps, will be directed by Matt Shakman, showcasing a diverse writing team collaborating on the script.

During the Marvel Hall H presentation at Comic-Con, it was confirmed that Pedro Pascal is set to portray Reed Richards, with Vanessa Kirby taking on the role of Sue Storm. Joseph Quinn from Stranger Things will play Johnny Storm, and Ebon Moss-Bachrach is cast as Ben Grimm. They will be joined by Julia Garner as Shalla-Bal (the Silver Surfer) and Ralph Ineson as Galactus, who is reported to be the film’s primary antagonist. Given these developments, it seems that Doctor Doom’s appearance may occur towards the film’s conclusion, potentially as a post-credit scene.

Avengers: Doomsday is anticipated to hit theaters on May 1, 2026, while The Fantastic Four: First Steps is scheduled for release on July 25, 2025.
