Robert Downey Jr. as Doctor Doom? Marvel's Secret Plans After Avengers: Secret Wars (2026)

Is Robert Downey Jr. Set to Transform into Doctor Doom? The latest buzz in the Marvel universe suggests that Marvel Studios is keen on having Robert Downey Jr. take on the iconic role of Doctor Doom following Avengers: Secret Wars. Could we be witnessing the emergence of the Infamous Iron Man?

Back in 2008, when Marvel Studios and director Jon Favreau made the bold decision to cast Robert Downey Jr. as Tony Stark in Iron Man, it was seen as a gamble. At that time, Downey had a complicated past that, while he had overcome many of his struggles, still raised concerns for some. Additionally, he wasn't yet a major box office draw, and Iron Man was considered a lesser-known superhero. Given these factors, Marvel's Kevin Feige and his team had little to lose by taking the risk.

The outcome was a spectacular success. Iron Man quickly became a critical and commercial triumph. Although Iron Man 2 received a more mixed critical reception, it still performed well at the box office, and Iron Man 3 made history as the first film in the Marvel Cinematic Universe (MCU) to surpass $1 billion in earnings. Through these films, Downey solidified his status as one of the biggest attractions in the Avengers franchise, earning unprecedented paychecks for films like Captain America: Civil War and Spider-Man: Homecoming.

In 2019, Robert Downey Jr. concluded his 11-year journey in the MCU with Avengers: Endgame, where the character Iron Man made the ultimate sacrifice to defeat Thanos, delivering a powerful farewell. However, as the narrative evolves beyond this saga, and with Jonathan Majors' Kang not being the primary antagonist for the Multiverse Saga, insider reports from Daniel Richtman suggest that fans might see Downey donning the mantle of Doctor Doom, a role he was rumored to be unveiled for at the 2024 San Diego Comic-Con. After a brief introduction in The Fantastic Four: First Steps, he is expected to play a significant role in both Avengers: Doomsday and Avengers: Secret Wars.

But here's the twist—this may not be the last we see of Downey as Victor Von Doom. According to sources, Marvel Studios has plans for him to continue this character arc beyond Secret Wars, potentially leading into the upcoming Mutant Saga. It remains uncertain whether he will emerge as a formidable foe for the Fantastic Four or take on a new iteration of Iron Man’s character. The latter possibility is actually quite intriguing.

In the comic books, after the events of Secret Wars, Doctor Doom underwent a transformation where he healed his disfigurement and reemerged as the "Infamous Iron Man." This storyline, while controversial among fans, could pave the way for Downey to revisit his most iconic role—but this time in a morally ambiguous light as a villain who seeks to do good. What an engaging character development that would make following the next Avengers films!

While we await confirmation on Downey's future as Doom, it seems we won't be saying goodbye to him after the upcoming Avengers movie set for release in December. And let's be honest, wrapping up his narrative there would be an absolute disservice to the character's legacy.

Avengers: Doomsday will feature a star-studded cast including Chris Evans, Chris Hemsworth, Anthony Mackie, Winston Duke, Tom Hiddleston, Sebastian Stan, Letitia Wright, Paul Rudd, and Robert Downey Jr. Additionally, 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 make their debuts in the Avengers series. The Fantastic Four: First Steps will showcase talents such as Pedro Pascal, Vanessa Kirby, Ebon Moss-Bachrach, and Joseph Quinn, alongside notable actors from the X-Men franchise like Kelsey Grammer, Patrick Stewart, Ian McKellen, Alan Cumming, Rebecca Romijn, and James Marsden. Furthermore, Ryan Reynolds and Hayley Atwell are also rumored to appear in Avengers: Doomsday.

Directed by the Russo Brothers, Avengers: Doomsday and Avengers: Secret Wars are brought to life through a script penned by Stephen McFeely, a frequent collaborator on the Avengers and Captain America series. Michael Waldron, known for his work on Loki and Doctor Strange in the Multiverse of Madness, is also contributing to the project.

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