Marvel Studios has always been known for its shocking twists, but casting Robert Downey Jr. as Doctor Doom in ‘Avengers: Doomsday’ might be its boldest move yet. For over a decade, Downey was the face of the MCU as Tony Stark.
Additionally, to add more to his relevance, he was the one who saved the universe from Thanos by sacrificing himself. So, bringing him back as Victor von Doom, one of Marvel’s most infamous villains, feels like a fever dream. Now, a new theory explains Marvel’s thought process behind this decision.
Marvel Insider Claims Dr. Doom Will Be Taking Advantage Of Tony Stark’s Body

A wild new theory by trusted insider MyTimeToShine suggests that Downey’s casting isn’t just about getting a fan-favorite actor back. According to the rumor, his return could be tied to a sinister multiversal twist that connects Doom and Stark in a way no one saw coming.

“In Doomsday, Victor Von Doom takes advantage of his resemblance to Tony to present himself as an ally to the MCU,” the insider wrote on X. Moreover, if this theory proves true, it could completely redefine the MCU’s future. This adds a psychological layer to the conflict, as many Avengers still mourn Stark’s death. If Doom plays his cards right, he could achieve a lot.
Director Anthony Russo further fueled speculation in an interview with The Times, stating, “There’s nobody else in the world who could play this character the way he’s about to.” His words suggest that Downey’s Doom won’t just be another version of the character, he’ll be something entirely new. Additionally, this twist also makes Doom’s threat more personal.
Why And How Robert Downey Jr’s Doctor Doom Takes Over Tony Stark’s Body

‘Doctor Strange in the Multiverse of Madness’ introduced a terrifying ability called dreamwalking. It was forbidden magic that allowed a person to project their consciousness into a multiversal variant of themselves. Wanda Maximoff used this power to control her Earth-838 counterpart. Even Doctor Strange himself used dreamwalking, possessing the corpse of one of his variants to fight Wanda.

Now, imagine if Doctor Doom used this same ability, but instead of taking over a living person, he possessed a dead one, specifically, the corpse of Tony Stark. A fascinating theory suggests that the Doom we’ll see in ‘Avengers: Doomsday‘ is from an alternate reality where Galactus destroyed his world. Unable to physically escape to Earth-616, Doom turns to dreamwalking to survive.
He needs a strong, stable vessel in this new universe, and who better than Tony Stark, one of Earth’s greatest minds? If this theory holds up, it would explain several things. Why Robert Downey Jr. is playing Doom in the first place? Doom could also be wearing g his legendary mask to cove rupees Tony’s face.
All in all, it’s safe to say that this would be one of the darkest twists in MCU history. The Avengers, who still mourn Stark’s sacrifice, would be forced to fight his reanimated body, now under the control of one of the most dangerous beings in the multiverse. And even worse? There’s a possibility that a remnant of Tony’s consciousness still exists,
