For over a decade, Robert Downey Jr. was the heart of the Marvel Cinematic Universe, bringing the beloved Tony Stark, better known as Iron Man, to life. His journey came to a heartbreaking end in ‘Avengers: Endgame’, when Stark made the ultimate sacrifice to save the universe.
Fans mourned his departure, believing that his Marvel story had concluded for good. Now, his return as Dr. Doom has been confirmed in ‘Avengers: Doomsday’ and Director Joe Russo shared Downey Jr.’s dedication to the role.
Joe Russo Claims Robert Downey Jr. Is Dialed In For His Dr. Doom Role

Robert Downey Jr’s return was unveiled in dramatic fashion at Comic-Con last July, where he took off his mask onstage to reveal himself as the new Doctor Doom. The announcement reignited excitement for the franchise’s future. Addressing the crowd, Downey cryptically remarked, “New mask, same task.”

“If we’re going to bring Victor Von Doom to the screen, he is one of the more complex characters in all of comics, then we are going to need the greatest actor in the world,” Joe Russo added. Moreover, it’s clear that Downey isn’t approaching this role lightly. According to Joe Russo, the actor has been deeply immersed in developing the character.
He is even writing backstory notes, brainstorming costume ideas, and truly getting inside Doom’s head. “He is so dialed in,” Russo said in a recent interview with ET. “I think he just loves really rich, three-dimensional characters. And I think he sees a real opportunity here with that character.”
Doctor Doom Will Be A Multiversal Villain Like Thanos

As excitement builds for ‘Avengers: Doomsday’ and ‘Avengers: Secret Wars’, details about Doom’s role in the films are beginning to emerge. According to The Cosmic Circus, Doom won’t be a typical villain driven by greed or chaos, his motivations are far more layered, just like Thanos.

The leaked reports suggest that Doom’s primary mission is to stop Multiversal incursions, events where universes collide, leading to potential collapse. With ‘Loki’ Season 2 introducing the concept of He Who Remains (a Kang variant) controlling the Sacred Timeline, Doom reportedly sees this as an injustice.
He wants to reclaim the freedom of his timeline and reshape reality according to his own vision. In his mind, he’s not a villain; he’s a liberator. Additionally, the first leaked concept art has already set social media on fire. Fans are impressed by Doom’s imposing new look. The idea of Downey stepping into the shoes of such a formidable, cerebral villain has many excited.
Moreover, if there’s anyone who can make Doom’s arrogance, brilliance, and inner conflict captivating, it’s him. With ‘Avengers: Doomsday’ on the horizon, anticipation is at an all-time high. So, will Doom be a villain fans love to hate?
