Shocking MCU Theory Explains Why Doctor Strange Will Join Doctor Doom In Avengers: Doomsday

by

A popular theory within the Marvel Cinematic Universe suggests Doctor Strange might hold the key to understanding a potential connection between Iron Man and Doctor Doom in the upcoming Avengers: Doomsday film. Ever since Robert Downey Jr. was confirmed to appear, fans have speculated about links between the two characters he plays, which was a natural reaction.

It was inevitable that fans would speculate about Robert Downey Jr.’s return to the Marvel Cinematic Universe, especially linking him to the villain Doctor Doom through the idea of alternate universes. While Marvel has used actors in multiple roles before, Downey Jr. is such a prominent figure that his comeback was bound to spark theories connecting him to a major character like Iron Man’s longtime foe.

Many theories have explored the potential connection between Iron Man (Tony Stark) and Doctor Doom in the Marvel Cinematic Universe. Since Marvel hasn’t revealed much about the upcoming Avengers: Doomsday movie, we still have a lot of unanswered questions. A new theory is now circulating that not only connects Iron Man and Doctor Doom, but also brings Doctor Strange into the equation.

Doctor Strange Is One Of The MCU Heroes With The Most Multiversal Knowledge

Overall, within the Marvel Cinematic Universe, Loki (Tom Hiddleston) understands the multiverse better than Doctor Strange (Benedict Cumberbatch). This is because Loki has directly experienced many different realities and timelines and is now responsible for protecting the multiverse. However, when looking specifically at the films, Doctor Strange is the one who’s been more central to exploring these concepts.

Both Spider-Man: No Way Home and Doctor Strange in the Multiverse of Madness introduced characters and concepts from alternate universes into the Marvel Cinematic Universe. The latter film specifically delved into dreamwalking, revealed Doctor Strange as a potential danger to the multiverse, and explained the meaning of incursions – a key element that will be important in future Avengers films.

MCU Theory – Doctor Strange Knew About Doctor Doom In Avengers: Endgame

A popular theory on Reddit suggests the upcoming MCU ‘Secret Wars’ event will be a repeating cycle. User MarioManRandySavage proposes that Doctor Strange, when viewing possible outcomes of the battle against Thanos, foresaw Robert Downey Jr. playing Doctor Doom, ultimately leading to the collapse of the entire multiverse.

Doctor Strange mistakenly believed Iron Man and Doctor Doom were the same person, and he prepared for Iron Man to make the ultimate sacrifice, hoping to prevent Doom’s rise. However, they are distinct individuals, and Strange actually ends up teaming up with Doom. If the events of Secret Wars are cyclical – constantly repeating – then Doom needs to be victorious so the entire multiverse can be reborn. This time, the reset won’t be caused by Kang’s victory, but by Doom’s.

Will Doctor Doom And Iron Man Be Connected In The MCU?

Although Robert Downey Jr. was announced to play Doctor Doom in a potential Avengers: Doomsday film, many believe his character should still have ties to Iron Man. The introduction of the multiverse and alternate versions of characters makes it simple to explain how Downey could return to the Marvel Cinematic Universe.

The Russo Brothers, in an interview with The Times, explained they couldn’t discuss Iron Man’s death because it’s crucial to the plot of the upcoming Avengers movie. This suggests the characters’ fates are all connected. A popular theory proposes Doctor Strange’s knowledge of Doctor Doom played a role in Iron Man’s death, which would align with the Russo Brothers’ statement about the interconnectedness of the story.
