- Quick Answer: Robert Downey Jr. hinted that Doctor Doom and Steve Rogers share an exciting, unexpected relationship in Avengers: Doomsday, teasing major Multiverse connections.
Robert Downey Jr. has hinted at his character Doctor Doom’s relationship with Steve Rogers (Chris Evans) in Avengers: Doomsday, as the two veteran Marvel actors return to the MCU.
It came as a big surprise to many fans when RDJ was announced to return in a different role for the new Avengers film, alongside Evans, after exiting the franchise following the release of Avengers: Endgame.
With several theories suggesting that Steve’s return could be connected to a broken timeline and that Doom may seek revenge, what will the dynamic between these two characters be like in Doomsday?
What Will Doctor Doom and Steve Rogers’ Relationship Be Like in Avengers: Doomsday?
Chris Evans, Hayley Atwell, and Robert Downey Jr. graced Good Morning America to talk about Avengers: Doomsday and what it was like working together again seven years after Avengers: Endgame.
RDJ was then asked who he enjoyed playing more between Tony Stark and Doctor Doom, to which he surprisingly revealed that he preferred the villain.
While he explained that he actually enjoyed observing everyone else, he then went on to describe his character’s relationship with Steve in the movie.
“I think that in Doomsday, what happens with our, this key relationship is so exciting and unexpected and beautiful,” he said.
He also revealed that there’s a reason for his and Evans’ return to the MCU, stressing that the latter doesn’t just easily say yes to projects without a good reason.
Surely, this revelation excites fans even more, but teasing Doom and Steve’s relationship as both “beautiful” and “exciting” might be a little unexpected.
As one of the leads and the main villain, viewers may expect the two to fight and hate each other.
As this sparks another set of theories, such as Captain America possibly bringing Tony Stark back to life after his death in Endgame, it remains to be seen what RDJ really means.
Will Tony Stark Return in Avengers: Doomsday?
With Robert Downey Jr. returning to the MCU as Doctor Doom in Avengers: Doomsday, fans can’t help but wonder if there’s a possibility for his original character, Tony Stark/Iron Man, to make an appearance, too.
While it remains to be seen if this will happen, given that Marvel has been keeping details about its projects under strict secrecy, it looks like Doomsday may be paving the way for the genius billionaire to return.
Avengers: Endgame will return to theaters with Avengers: Endgame Encore, featuring additional scenes that will connect the 2019 film with the upcoming Doomsday.
Naturally, details about the additional scenes have yet to be revealed, but they are expected to feature events that could connect to what is set to happen in the next Avengers film.
This may include new sequences involving Tony himself before his death during the Battle of Earth, as he may have actually known about the danger Doctor Doom could bring.
The line, “You mess with time, it tends to mess back,” heard in the Endgame Encore trailer, hints at some new context involving time travel and diverging realities in the Multiverse Saga.
As this seems to set up the events of Doomsday, it may also draw a clear parallel between Doom and Tony.
Sure, the ruler of Latveria may be wearing a mask, but if he ever removes it, it could reveal his likeness to Tony. This may also provide context for what Downey Jr. said about Doom and Steve Rogers’ “beautiful” relationship.
Avengers: Endgame Encore hits theaters on September 23, while Avengers: Doomsday is set to be released on December 18.
