Avengers: Doomsday Rumor May Reveal Bonkers Alternate Origins For Robert Downey Jr.'s Doctor Doom - Spoilers

According to a new rumor, Marvel Studios had some pretty out-there ideas in mind for Doctor Doom's (Robert Downey Jr.) origin story in Avengers: Doomsday...

We still don't know much about how Doctor Doom (Robert Downey Jr.) will be introduced or the villain's motivations in Avengers: Doomsday, but several different sources have reported on the same details of the character's backstory.

Possible spoilers follow.

Apparently, Steve Rogers' (Chris Evans) decision to remain in Peggy Carter's timeline at the end of Avengers: Endgame caused a Multiversal incursion that resulted in the deaths of Victor Von Doom's wife and child. This leads to Doom seeking revenge on the former Captain America at the beginning of Doomsday (this may be teased in Endgame's re-release).

It sounds like a relatively simple and effective explanation for why Doom would target Rogers and his fellow heroes, but if a new rumor is to be believed, Marvel Studios had a few alternate scenarios in mind before the story fully came together - some of which were pretty out there!

Doomsday didn"Doom’s origin story in’t always involve him having a family," writes MTTSH. "Other versions included his parents dying, one where he believed he was a reincarnation of Tony and that he 'belonged' in the MCU, and one of the most insane ideas had him working for Mephisto, who was the real bad guy. Another version had him obsessed with either Pepper Potts or Sue Storm."

The scrapped Tony Stark reincarnation origin is arguably the most intriguing, since it would seem to indicate that the studio was considering introducing a more direct connection between Iron Man and Doom.

From what we've been told, Doomsday will not address the reason both characters look so similar, and Downey will only be seen without his mask once or twice when no other characters are around.

It's entirely possible that some of the potential plot points mentioned above could still find their way into this movie, Avengers: Secret Wars, or future MCU projects.

Avengers: Doomsday and Avengers: Secret Wars were hit with significant delays last year, with Doomsday now set to arrive in theaters on December 18, 2026, and Secret Wars positioned for December 17, 2027.

Both movies will be directed by the Russo brothers, who also make their MCU return after helming Captain America: The Winter Soldier, Captain America: Civil War, Avengers: Infinity War and Avengers: Endgame

"Being able to create stories and explore characters within the Marvel Universe fulfilled a life-long dream of ours, and we discovered a powerful connection with audiences in each film that we made. We’re thrilled to collaborate once again with Kevin, Lou and the entire Marvel team to bring this epic adventure in storytelling to new and surprising places for both the fans and ourselves”, said The Russos in a statement after the SDCC panel.

Doomsday will star:

Paul Rudd as Ant-Man, Simu Liu as Shang-Chi, Tom Hiddleston as Loki, Lewis Pullman as Sentry, Florence Pugh as Yelena, Danny Ramirez as Falcon, Ian McKellen as Magneto, Sebastian Stan as Bucky, Winston Duke as M’Baku, Chris Hemsworth as Thor, Kelsey Grammer as Beast, James Marsden as Cyclops, Channing Tatum as Gambit, and Wyatt Russell as U.S. Agent

Along with Vanessa Kirby as Sue Storm, Rebecca Romijn as Mystique, Patrick Stewart as Professor X, Alan Cumming as Nightcrawler, Letitia Wright as Black Panther, Tenoch Huerta Mejia as Namor, Pedro Pascal as Reed Richards, Hannah John-Kamen as Ghost, Joseph Quinn as Johnny Storm, David Harbour as Red Guardian, Ebon Moss-Bachrach as The Thing, Anthony Mackie as Captain America, and, of course, Robert Downey Jr. as Doctor Doom.

@MV081199 - yes

Or that she just looked like Sue and was actually Valeria who was a love interest of Doom’s in the comics.

Meh. Seems lazy and convoluted. That Marvel has as much success as they have filming while still writing has been very lucky for them. But that luck will run out at some point and they’ll learn not to rush these gigantic tentpole films. They should have had a well thought out plan before they rushed the Russos into making these mega expensive movies. Maybe this turns out to be on par or better with endgame. Only time will tell, but I’ve lost a lot of interest in this Doom movie. In part bc of RDJ which is not a great casting choice imo, and because it seems so haphazardly put together. I sincerely hope I’m wrong and it’s amazing, but I’ve got low expectations.

The highlight of the movie will be seeing Steve Rogers again.

@MuadDib - Totally agree with you here.
I'm hoping for the best, but expecting the worse.
Bringing back RDJ as Doom is a huge mistake no matter how they try to handwave it.

@MuadDib - Well it's been 7 years since the last Avengers movie and by the time this will be released it will have been 2 and half years since this was announced at Comic Con. Its not really rushed if you're considering the time that's elapsed.

I don't think you're really hitting the issue that's plagued Marvel. The problem is they changed course from what had worked previously. After the greatest culmination in cinema storytelling like ever, they decided they could do whatever they wanted and be successful and what they wanted was stories in the vein of Captain Marvel (which was their one true stinker from Iron-man-leading all the way through Endgame). The idea was give the characters the look and powers from the comics but use them to push or endorse (subtly or not so subtly) whatever freakin socio-political message that mattered to the filmmakers at the moment (instead of trying with all their might to just capture the sense of the different comic characters and histories!). Because of this, the storytelling in Marvel suffered as did the authentic feel of the characters. Marvel has felt much more like cosplay than it did in former times.

Doomsday is honestly Marvel Studios admitting that they needed to course correct. Its unfortunate that they didn't build the movies up to Doomsday before this but it is way, way better than doubling down with the Kang story no one asked for. And turning back to the classic cast and Russos is far superior to turning to the gifted (but wrong for the genre) Chloe Zhao and cry-me-a-river-Simu-Liu for stewarding this incredible universe that's been built.

RDJ and the Russos delivered nnothing but great stuff formerly in the MCU. I expect the same to happen with Doomsday.

If true then I’m glad they went with the one they did since I don’t like the Tony reincarnation idea or him being obsessed with Pepper or Sue (even though he has had a thing for the latter in the comics).

Not particularly fond of him working for Mephisto either but that could have worked depending if it was more of a quid pro quo situation given that in the comics , Victor’s mother Cynthia was a practitioner of the dark arts who made a pact with Mephisto for her soul in exchange to help her people which led to her being damned to hell so if they had gone that route , perhaps Doom was willing to help Mephisto in whatever cause the latter desired in order to free his mother but oh well…

Also seeing RDJ & Sacha Baron Cohen together could have been fun too!!.

Anyway given that Doomsday seems to be somewhat about father/parenthood , i guess it makes sense for this Doom (akin to Iron Man:Armored Adventures) having had a family aswell!!.

Anything but giving him his comic-accurate origin. Marvel's greatest villain reduced to another generic bad guy.

Thanos worked so well, not only because he was teased for years, but because he was not a petty powerful being looking for revenge. His motivation was unique, bringing balance to the universe. Imagine if Thanos was after Spider-Man because yet again he was wronged by Stark somehow. It would have been way less interesting.

@JayBarrick - You complain about MCU not using comic-accurate origins, but then praise their non-comic-origin for Thanos (who was still petty and vengeful).
JayBarrick
JayBarrick - 4/30/2026, 7:38 AM
@Rosraf - Hi!

First, I'm not complaining about the MCU as a whole. I'm critiquing this specific creative decision.

Second, yes, I'm aware of the contradiction. However, the critique is about which changes are for the better:

a) Infinity War Thanos was not petty. He had a goal, framing himself as a logical savior. His logic was dispassionate. After achieving his goal, he didn't need validation. He retired to a lonely planet, thinking he had acted for the greater good—he wasn't looking to be proven right all along, nor was he trying to stroke his own ego.

b) Endgame Thanos was petty. This time-displaced, less mature Thanos was far less interesting. The logic behind his decision to time travel to the present-day MCU after learning of his victory and death was faulty and petty. He did so out of ego, whereas he could have simply prevented his death in his own timeline after the snap, since he knew his fate at the hands of Thor. This iteration of Thanos felt out of place; he was necessary as a physical threat for the plot, but his actions weren't justified by the character himself. It gave us a satisfying final confrontation, but he was far less interesting than Infinity War Thanos, and many people expressed that he felt plain and boring, riding on the audicence succcess of the former.

c) Ironically, Infinity War Thanos felt slightly closer to comic book Thanos to me. Though neither of these versions of Thanos was literally courting Death (as the character had not been introduced, nor was he close to doing so at that point), there was a metaphorical likeness to that idea in that he sought Death as an endgame. Endgame Thanos, however, didn't court Death at any point, except on the battlefield like a generic villain.

Third, Dr. Doom has much more nuanced and interesting roots in the comics than Thanos, and certainly more than the apparent iteration in Doomsday who goes after Steve because of his dead family. Comic book Dr. Doom is petty, for sure, as his ultimate downfall is his own ego. But his development from an F4 villain to a universe-level threat—matching powerhouses like Tony Stark and Dr. Strange in power and intelligence—as well as being the ruler of his own nation, gives him a complex layer of power dynamics (similar to Black Panther). This is what elevates him from a "generic petty villain out for revenge" to a "dangerous threat that cannot be underestimated under any circumstances."

Of course, we don't know how Doomsday's Dr. Doom will work. But I don't think Marvel Studios will take the time or put in the effort to explore all his intricate connections to the Richards family, specifically his animosity toward Reed. They won't have time to explain how Dr. Doom could have been Sorcerer Supreme, plotting against Dr. Strange when they were young, only to lose because of his ego, even though his ambition was perfectly matched by his skills. They won't put in the effort to explain how he is a diplomatic, political figure who, for better or worse, is able to rule a nation and make his citizens happy enough to defend him.

They could have. Had they started from, say, the aftermath of Sokovia in Age of Ultron, used him in a Dr. Strange movie, and watched his rivalry with Reed grow... Sure, they didn't have the rights to the F4 at that time, but since the FOX acquisition (officially in March 2019), it has been 7+ years. They could have done more. The pivot from Kang to Doom, the casting of Downey Jr., and the return of Steve Rogers speak for themselves.

So yeah. I complain.

@JayBarrick - Haven't you heard: you can't question anything Marvel or Disney or you get some label. You can even be a Marvel fan but if you ask why RDJ is being brought back as Doom, some people flip out. Just consume product and NEVER ask questions according to them.

Oh yea of little faith.

The boy’s an actor. He knows what needs to be done.

@MarkCassidy - “Doomsday didn"Doom’s origin story in’t always involve him having a family," writes MTTSH.”

Yikes, MTTSH surely didn’t write that mess of a sentence Mark (I checked).
AntiDragon613
AntiDragon613 - 4/29/2026, 9:48 PM
So, this tells us they had already been planning on casting RDJ in the role before they had ever come up with any sort of sensical narrative reason to bring him back. That’s kind of a bummer, and I fear that any reveal behind why Doom looks like Tony (if they even bother to draw a link between the two) is going to have all the emotional impact of a wet fart.
TheVisionary25
TheVisionary25 - 4/29/2026, 11:28 PM
@AntiDragon613 - it’s a quirk of the universe I feel

Granted Evans casting as Cap was in hindsight but why does Johnny Storm look like Steve Rogers…

No reason is given and honestly doesn’t need to be when dealing with the multiverse imo

This Doom just happens to look like Tony and if they they play into that , I could see some emotional
Impact happening on people that were close to him or knew Tony like Thor and Steve which could be effective but we’ll see.

AntiDragon613 - 4/30/2026, 1:23 AM
@TheVisionary25 - I’m not talking about an in universe justification as to why two different characters might share the same face, I’m talking about how if these rumours are true and they were floating several different RDJ related Doom backstories around, that means they didn’t have a finished script when they were already planning on casting him as Doom. This is worrying, as it would imply they prioritized the stunt-casting of it all over actually having a solid story in mind that would necessitate bringing back RDJ. With Evans they were at least calling back to the previous Fantastic 4 films, but with this Doom casting it seems like they just expect us to not ask too many questions. Sure, they’ve established that in this multiverse anyone can look like someone else, but bringing back such a huge star in a new role and then not having some interesting twist to it is a bit underwhelming, and stinks more like a corporate PR move. To me, that doesn’t inspire much faith in the actually creativity behind the script for this film, which is the point I was trying to make. Hopefully they were able to figure out a worthwhile story and prove my doubts unfounded, and even if this was just a stunt to draw in more at the box office it won’t actually show in the final product, but colour me skeptical for now (if these rumours are even true).
TheVisionary25
TheVisionary25 - 4/30/2026, 5:55 AM
@AntiDragon613 - fair enough I guess.

Feige has said that they came up with the idea of RDJ as Doom in early 2023 , before the Russo’s and McFeely had joined the film since RDJ was the one that tried to convince them to come back so I feel the idea definitely came before the script since there wasn’t really one for Doomsday then.

K....

OT:What do you guys think of this lineup for a Disney+ TV-MA shadow ops "Dark Avengers" series?

Bullseye
Wonder Man
The Punisher
Elektra
Baron Zemo
Baron Mordo

And the series can be about how The Dark Avengers are a shadow ops team ran by Mister Charles who runs the team by what Valentina De Fontane dictates. They are the assassins of the US Government while the New Avengers are the heroes of the US Government. As the series goes on, Zemo learns more about Val and her intentions and eventually convinces every but Frank Castle and Elektra to join his team who Val dubs The Masters of Evil when the series ends.

@SonOfAGif - 🙄🤔😐🎯🎯🎯🎯

I love it! Throw in the Swordsman, who embarks on a journey to find the mythical sword known as the "Ebony Blade", bring back Skurge, who now protects the Enchantress, and get that ball rolling.

I'd love to see HBO put together a show of this magnitude. The Fixer constantly upgrading gear, a proper Wrecking Crew ([frick] everything mentioned in She-HULK), a power struggle with Dr. Octopus v Zemo (who reignites Ultron), Boomerang and Bullseye become bffs, this could go on for several seasons!

The biggest wtf- I think the combined efforts of James Gunn & Taika Waititi could pull this off, lol. No jokes told. Let the action do the comedic lifting. I'd watch...

meh. We will see.
Dooms mother SHOULD factor into it. She was such an influence on his journey and decision making.
I do love the rumor that they will not even address the likeness of the two characters. thats perfect IMO.
Im glad they did not do the former story that would have been a FOX universe one where he WAS Tony Stark who adopted the Victor Von Doom name after being scared.. That would have been shit and something Ratner would have written.
Lucasberg
Lucasberg - 4/30/2026, 12:43 PM
They will address the similar look between Tony and Doom but only to identify that as they both look similar and both having soaring intellects, they are total opposites. This will not be a Stark variant. This will be Victor Von Doom from another universe who if anything will view himself as the savior of a reality that in his mind, Tony Stark will have failed.
