The actor will play the role of supervillain Victor von Doom (also known as Doctor Doom) in the 5th and 6th Avengers films, titled Avengers: Doomsday and Avengers: Secret Wars.

Downey Jr. made his dramatic entrance at the convention in a Doom costume, surrounded by replicas of Doombots. He then removed his silver mask and revealed his face to shocked fans who gave him a standing ovation.

The two films will be directed by Anthony and Joe Russo, the brothers who directed 2019’s Avengers: Endgame.

Avengers: Doomsday is set to premiere in May 2026, followed by Avengers: Secret Wars, which is expected to premiere in 2027.

Marvel Studios also made the announcement on Twitter, sharing a poster for the upcoming film with the caption, “Just announced in Hall H: The Russo Brothers return to direct Marvel Studios’ Avengers: Doomsday, starring Robert Downey Jr. as Doctor Doom. In theaters only May 2026. #SDCC.”

Doctor Doom is one of Marvel’s most iconic supervillains and the archenemy of the Fantastic Four.

He is a genius scientist with a tragic past.

Tony Stark (the genius behind Iron Man) and Doom share several similarities: they both wear metal masks, they are both incredibly wealthy, and they both possess extraordinary intellects.

Avengers 5 was previously called Avengers: The Kang Dynasty.

After Marvel dropped Jonathan Majors in December 2023, the series was retooled with a new title and direction.

Majors was set to play villain Kang the Conqueror in the films, but the studio canceled his role after he was found guilty in a domestic abuse case.

Downey had said in recent interviews that he was open to returning to Marvel, but fans assumed he meant he would return as Iron Man (Tony Stark).

He first played the role of playboy super-genius Stark in 2008’s ‘Iron Man’.

The actor went on to play the role in 10 Marvel films spanning 11 years, including ‘Iron Man 2’, ‘Iron Man 3’, ‘The Incredible Hulk’, ‘The Avengers’, ‘Captian America: Civil War’, ‘Avengers: Age of Ultron’, ‘Spider-Man: Homecoming’, ‘Avengers: Infinity War’ and Avengers: Endgame.

Endgame saw Iron Man’s death. Last December, Feige said Vanity Fair that he had no interest in undoing the emotional moment to bring the character back.

“We’re going to hold on to that moment and never touch that moment again. We’ve all worked so hard, for many years, to get there, and we would never want to magically undo it.”

Meanwhile, Downey Jr. has indicated that he would like to return to the franchise.

After winning the Oppenheimer Oscar, he was asked if he would be interested in returning to the Marvel Cinematic Universe.

“Thankfully. It’s too integral a part of my DNA,” he said Squire magazine in April.

“That role chose me. And look, I always say, ‘Never, ever bet against Kevin Feige.’ It’s a losing bet. He’s the house. He’s always going to win.”

The new casting is the culmination of a successful year for the actor.

In addition to his Academy Award win for his role as Lewis Strauss in Christopher Nolan’s Oppenheimer, he was also recently nominated for an Emmy for his role in Park Chan-wook’s HBO miniseries The Sympathizer.
