Summary
- Robert Downey Jr. has been confirmed to be playing Doctor Doom in the MCU's upcoming Avengers: Doomsday and Secret Wars.
- If following Marvel Comics' Secret Wars story from 2015, Doctor Doom could steal a multiversal figure's power to build Battleworld in Phase 6.
- Loki would be the perfect enemy to Doctor Doom in Avengers: Secret Wars, especially after his heroic turn in 2023's Loki season 2.
According to a new MCU theory, a major Doctor Doom power mystery has already been solved, which could perfectly set the stage for Marvel Studios'
Avengers: Secret Wars. With the Russo brothers returning to direct Avengers: Doomsday and Secret Wars, the Phase 6 crossover movies promise to be sights to behold, especially since Robert Downey Jr. will debut as Doctor Doom. Little is known about Doomsday and Secret Wars' storylines, but it's likely the events of Marvel Comics' Secret Wars stories - some of the Russo brothers' favorites - will be adapted faithfully.
Marvel Comics has explored the Secret Wars storyline twice, though there are noticeable differences between these two expansive events. Released in 1984 and 2015, both Secret Wars stories give Doctor Doom a pivotal role, meaning his inclusion in the MCU's upcoming Avengers: Secret Wars is paramount.
Marvel Studios seems to be relying heavily on 2015's Secret Wars for the Multiverse Saga, which dealt with multiversal incursions, variant heroes and alternate worlds, so it's possible Doctor Doom could be given the same major power upgrade from this event in the live-action MCU.

4 Doctor Doom's Powers Need To Change For Avengers 5 & 6

It's unclear what power set Robert Downey Jr.'s Doctor Doom will already have when he joins the MCU in Phase 6, but it seems likely that he will be given even greater abilities in Avengers: Secret Wars. During Marvel Comics' Secret Wars event in 2015, Doctor Doom faces the otherworldly Beyonders, and steals their powers with the help of Molecule Man.
This gives him the abilities necessary to piece together Battleworld from the fragmented pieces of incursion-destroyed realities, which culminates in him establishing himself as "God Emperor Doom."
Marvel Studios has been exploring the many complex concepts of the multiverse since Phase 4, which was also the core focus of 2015's Secret Wars event. This has led many to believe that this storyline will be adapted as faithfully as possible in the MCU, which means
it's very possible we'll see Doctor Doom steal power from Beyonder-like beings, build Battleworld from the broken pieces of many alternate universes, and become the most significant villain in the franchise's history. One new theory explains exactly how Doctor Doom can begin this journey in Phase 6.
Loki May Replace Marvel Comics’ Beyonders In Avengers: Secret Wars Close Marvel Studios hasn't provided any hints toward the existence of the Beyonders in the MCU, suggesting that these otherworldly figures may be replaced by something else in Avengers: Secret Wars. After the events of 2023's Loki season 2, Tom Hiddleston's former God of Mischief is the perfect candidate to replace the Beyonders in the Secret Wars storyline.
It's the Beyonders' immense power that allows Doctor Doom to build Battleworld after incursions ravage the multiverse, and Loki now has a similar level of power in the MCU.
Loki season 2's finale saw Loki destroy the Temporal Loom and gather the branching realities of himself, fating himself to sit guard over them for all eternity, ensuring that they are kept safe, while the TVA hunts for dangerous variants.
Loki became a bona fide superhero in Loki season 2, sacrificing his own freedom to sit for eternity guarding the infinite branching timelines of the multiverse. However, since Avengers: Doomsday and Secret Wars are expected to put the multiverse under threat, it makes sense that Loki might put these duties on hold.
If Doctor Doom steals Loki's multiversal powers in Avengers: Secret Wars, the Asgardian trickster would be free to join his former enemies, and long-lost brother, Thor, in the battle against Robert Downey Jr.'s new villain, creating a wonderful full-circle moment.
Loki Is The Perfect Villain For Robert Downey Jr.’s Doctor Doom

In Marvel Comics, Doctor Doom is the archenemy of the Fantastic Four, but has also faced almost every other hero in the Marvel Universe. This will likely be the case in the MCU, too, particularly given recent speculation that Robert Downey Jr.'s Doctor Doom will debut in The Fantastic Four: First Steps. However, while Doctor Doom will likely battle a plethora of powerful heroes,
Loki would be his perfect antithesis, as Downey Jr. and Hiddleston's original MCU roles have now been completely switched.
Back in 2012's The Avengers,
Robert Downey Jr. portrayed the heroic Tony Stark, a.k.a. Iron Man, while Tom Hiddleston played a more villainous version of Loki, hellbent on taking over the Earth. In Avengers: Secret Wars, Loki will be seen as the heroic savior of the multiverse, while Downey Jr. will be returning to the MCU as one of Marvel's most significant and recognizable villains. The actors' history in the MCU makes them the perfect enemies in
Avengers: Secret Wars, so the possible battle between Loki and Doctor Doom is a very exciting prospect.
