The "Cave Nexus Point": How a different cellmate in Iron Man (2008) could have created Dr. Doom
I know the RDJ casting feels like nostalgia bait, but there is one specific path Marvel could take that would make this the most devastating villain arc in cinema history. It all goes back to the cave in 2008, and a single change in who was sitting in that cell with Tony Stark. **If you replace the man who saved his soul with someone who fed his ego, you don't get Iron Man**...**you get Victor von Doom.**
I hear everyone’s concerns about the RDJ casting feeling like a desperate move, but the more I obsess over the 2008 *Iron Man* origin, the more I’m convinced that Marvel is planning the ultimate "what if" scenario. Think about the fundamental turning point in Tony Stark’s life: the cave. In our timeline, he was stuck with Ho Yinsen, a man of science and peace who taught Tony that his heart was worth more than his weapons. But imagine a timeline where that "Nexus Point" shifted. Instead of Yinsen, Tony is imprisoned with an exiled sorcerer or a practitioner of the mystic arts from Latveria.
In this scenario, the transition from Stark to Doom becomes inevitable and incredibly grounded in the lore we already know. When Tony is forced to build a way out, he doesn't just rely on scrap metal and engineering; he’s introduced to the world of the occult at his most desperate moment. He realizes that tech alone has limits, but tech infused with ancient, forbidden magic is absolute. This version of Tony doesn't leave that cave with a sense of humility or a desire to protect; he leaves with a God complex, believing he’s the only one capable of merging science and sorcery to "fix" a broken world. The "suit of armor around the world" isn't a satellite system anymore, it's a global dictatorship.
This is honestly the only way the casting makes narrative sense. If you just hire Robert Downey Jr. to play a completely unrelated Victor von Doom, you’re wasting the most iconic face in cinematic history. The emotional weight of *Avengers: Doomsday* shouldn't just come from a scary villain; it needs to come from the trauma of the survivors. Imagine Peter Parker or Rhodey finally tearing that mask off, expecting a stranger, only to see the face of the man who died to save them, now twisted by dark arts and a totalitarian ego. It turns the movie from a generic superhero fight into a psychological nightmare for the Avengers.
Ultimately, this theory bridges the gap between the "Iron Man" legacy and the "Doctor Doom" future perfectly. It respects the 616 Tony’s sacrifice by showing us exactly how close he was to becoming the world's greatest threat if he had just been given a different mentor in that cave. It justifies the RDJ return as a brilliant narrative choice rather than a marketing gimmick, giving us a villain who is a dark, distorted mirror of the hero who started it all.
**At the end of the day, I realize this is mostly just me coping and trying to find a narrative reason to be excited again. This is definitely my own headcanon for what I** ***wish*** **would happen, but deep down, I’m fully aware that Marvel is probably just hitting the panic button.** Bringing RDJ back feels like a 'break glass in case of emergency' move to keep the franchise on life support by banking on nostalgia and the biggest name they have. Still, if they’re going to go this route, I’d much rather see a complex, dark 'Stark variant' story like this than some lazy explanation of why Doom happens to have Tony’s face. A guy can dream, right?

It gives doom a beginning that is already emotionally charged, but it corrupts the nostalgia into a horror story for the characters.
Don't listen to the haters. AI translation for non native speakers is one of the tools AI should stick around to do.
Great thoughts, and thanks for sharing.
My understanding was that he’s playing specifically Victor Von Doom who happens to have MCU Tony’s face. Kinda like how Steve Rogers and Human Torch share a face, but are unique characters.
To me that’s the cop out. Having Doom learn that he happens to share a face with the MCU’s biggest hero, and uses that against them, is interesting.
Having “what if Tony but evil” is not interesting.
>To me
I am.
“Oh we have this super iconic villain with decades worth of story, but we’re gonna deliberately fuck it up to explain why he looks like RDJ.”
But yeah. Making him a Tony variant undermines the character for the sake of nostalgia baiting.
They also told us Chris Evans wasn't going to be in Doomsday. They told us Tobey and Andrew weren't going to be in No Way Home. When someone correctly guessed the subtitle of Avengers Endgame, they said that was wrong.
Don't believe anything they tell us.
“Doom isn’t a Tony variant, because Tony is a Doom variant! He’s the only one who got out of the cave unscathed. The entire MCU prime timeline is a what if scenario! Mwa ha ha haaaaa”
Doom didn’t go in to the cave, Tony did.
I have no Horse in this race. I don’t personally care if Doom is a Stark or not, although I can see some cool story potential from a Stark variant, and other potential to a ‘this is not Dooms true body he’s dimension walked his consciousness into Stark’s body’ story.
I do not think it would be a good idea to cast RDJ in any role in the MCU and rely on suspension of disbelief for his similarities to the franchises man face. It would confuse general audiences a lot and maybe even put some of them off. In a slapstick break the fourth wall comedy like Deadpool or She-Hulk it works because you can have a laugh with it, but IMHO they shouldn’t really be included in the mainline canon of the flagship movies.
No offense to OP, but I don’t know why people want Doom to be related to Tony.
Even if Tony was introduced to magic, why would he take up a different name? And they’d have to abandon all of Doom’s background story.
Tony Stark’s story is finished. He’s done. It shouldn’t be touched again. They brought back RDJ simply because of nostalgia first, and acting skills (imo) second.
I hope to god they give Doom a really fucked up face so RDJ isn’t recognisable at all. No character should acknowledge that he looks similar to Tony.
>I hope to god they give Doom a really fucked up face so RDJ isn’t recognisable at all. No character should acknowledge that he looks similar to Tony.
I refuse to believe that Doom will have zero reference to Stark. He's either a variant or being multiversal happens to look just like him (and could use that to his advantage) or something. *Unless* we never actually see RDJ's face. Either because he's too scarred up or he never takes off the mask. But if we see RDJ and *nobody* mentions him looking like Stark, I will be a little irritated.
Say it again for the people in the back
Sorry, best we can do is Captain ~~Carter~~ Doom.
Say it again for the people in the back
I agree but unfortunately you KNOW that once they get Tom Holland Spider-Man in there, they'll have a moment where his face is revealed and the 30 year old Holland will stammer and say "M-m-mr. Stark?"
The MCU 616 is therefore the only universe where the hero known as "Iron Man" looks like RDJ. Every other universe knows that guy as Doom, and their Tony Starks all look like Tom Cruise.
I kinda dig this idea. I’d be happy with this if it’s the way they are going afterall
Didn't even bother reading the whole thing coz it irked me a bit.
I'd be so hyped to find that Jeffrey Wright has been cast in Doomsday. I know Uatu could be played by anyone but I think people would prefer if it's him as we've come to associate his voice with that character now.
But also yeah, great theory, I could roll with this as long as it's kind of a quick backstory tastefully done.
They could even sort of dupe the audience with a straight up 5 mins from IM1 up to the part that is leading into your idea.
It's gonna be the same situation, Tony and Victor will not be variants of each other and the only quality they will share is they have the exact same face though Doom's will most likely be disfigured anyway.
If Marvel wants us to take Doomsday seriously, we will need an explanation.
As long as people can ACCEPT that MCU Doom is not comics Doom and will have his mask off sometimes, I think everything will be ok.
I like your idea. But I am not concerned with that plotting. Whether Doom truly looks like Stark and is merely a coincidence, or he doesn’t look like Stark and it is a scam, or he’s a variant or vice versa, or some other reason, I am not worried about that. They’ll make it work.
Comic fans just need to get on board with the idea that Doom is going to have his mask off at least 25% of the time (unlike the comics where it is off 0.0000001% of the time).
Marvel were developing this saga in 2018 and probably brainstorming ideas even earlier. Long before any critical or financial failures.
In 2019 Kevin Feige said they had a “five year plan”. Lo and behold just a few years later they announced Secret Wars for a *2025* release, *still before* their string of misses. RDJ was contacted about Doom *before* Kang/Majors were dropped.
Avengers 4 left us with questions. Avengers 5 will answer them. Pretty basic sequel stuff here. This was always going to happen in either these next two Avengers movies regardless of what “bombed” and what didn’t.
This isn’t the big desperation play people think it is. An actor got fired, they didn’t think his character was a fitting villain for the story they wanted to tell *about the Avengers*, so now we got a villain more suited for the story. Like, why are we shaming Marvel for cleaning things up?
I don’t get it.
And this is in the context of Marvel having an unprecedented amount of box office failures / disappointments in the last couple of years?
2025 - 3 movies - 2 box office failures 1 likely break even (break even is still disappointing).
2024 - One successful movie not really related to the MCU (Deadpool)
2023 - 3 movies - one failure, one break even (which is still disappointing), one moderate success.
If you take out the unrelated movie, you get 1 moderate success and 5 failures in 6 recent movies. That’s the worst financial performance we’ve had from Marvel.
No way anyone there was actually having this plan for *Secret Wars* back then. Do you know how many projects between 2018 and 2025 we've gotten, and how many of them actually have anything to do with Doom?
>Avengers 4 left us with questions
What questions did it leave us with?
>they didn’t think his character was a fitting villain for the story they wanted to tell *about the Avengers*
This makes no sense. They were the ones deciding to use this character (one of the biggest Avengers villains in the comics), they were the ones who wrote him to be the next big thing (he literally states he's killed multiple Avengers). Everything about the multiverse shenanigans was directly tied to Kang.
Then Majors' issues and deciding to change Quantumania's outcome due to negative test screenings, when they should have just stuck with actually making that character a threat and recast the actor, when his entire schtick is he has multiple variants that are threats.
Bringing back RDJ is a desperation move. The entire *Doomsday* talk revolves around RDJ, they aren't paying him 100 MILLION dollars when they could have gotten thousands of other actors for this role.
Feige started with the 2000s X-Men and always had the vision to have them cross paths with the rest of Marvel. It’s been a fan pipe-dream for the Fox, Sony, and MCU casts to share the screen for decades
Now everyone’s established and under the same roof, they can. Makes sense for a multiverse saga. And in doing so, give a final bow to legacy cast while setting up the future MCU that includes F4, X-Men, and everyone else
This has undoubtedly been the plan since the late 2010s. RDJ and Evans were always coming back. The only surprise is RDJ as Doom
Box office performance and this reality are not mutually exclusive. Even if people are too simple to connect dots or too eager to default to ‘panic’ or ‘nostalgia’ as straw man arguments
They already said its going to be Victor von Doom.
Doom isn’t a Tony variant, Tony is a doom variant
> If you replace the man who saved his soul with someone who fed his ego, you don't get Iron Man...you get Dead Tony Stark.
Like, I think it was pretty clear in that movie that if Yinsen isn't in that cave, and they don't do the Exact Thing They Wind Up Doing, the Ten Rings murder Tony.
I've also just never really liked the One Bad Day thing that's so prevalent in multiverse comics, but that's just me.
In WS. Steve visited the museum and Peggy talks about Steve saving the allies and the man that would later become her husband, they show pictures of her kids. But don’t show the husband, so Steve staying in the past had to branch the timeline and somehow causes incursions for doom
get this AI slop out of here
But it makes sense that the lazy people desperate to keep AI around are too lazy to scroll far enough to see these other comments calling out the lazy AI slop
No it isnt. Sometimes people in the multiverse jist look like each other. Like Chris Evans as Captain America and Human Torch, both in the MCU now.
I think it's more interesting that they're going to have to acknowledge that fact without fourth-wall breaking.
So with all that said, if you are telling me they are doing it because they want to refocus and then re-examine how Tony was changed by Yinsen in that cave. Re-examining that great act of the movie and that amazing choice for character arc...well hot damn would I change my tune. Great idea by you, I'm really intrigued (but also agree this is just copium).
- Most iconic face in cinematic history
Are we being serious?
Wrong. We have already seen unrelated characters bearing the same face. Doom could easily dreamwalk into Stark's body. Or Doom's face, when healed, resembles Stark's face.
Also your theory is wrong because this would mean Doom exists since 2008, but as we know:
1. Victor von Doom is Victor von Doom.
2. Victor von Doom is Reed Richards' colleague and Fantastic Four is set in a technologically advanced '60s setting.
3. Latveria exists in 828. The Latverian leader has no excuse to avoid the F4 in a world where every country is united for a common cause under the F4 and especially when the world is at risk, unless Latveria's leader is a powerful dictator who rules with an iron fist, which is obviously Doom.
4. Tony isn't a Doom variant because there are multiple Tonys across the multiverse as shown in What If (and I don't see any reason HWR has to "place a Tony Stark" somewhere), and Doom isn't a Tony variant because the Russos said so AND Howard Stark doesn't exist or has any reason to exist in 828.
The reason why the Russo brothers said Doctor Doom's rise is directly tied into Tony Stark's death is most likely that Tony would've tried every method possible to stop Doom from causing damage to the multiverse. After all, his act of launching the nuke towards the Chitauri mothership in space made him infamous across the whole galaxy. He was able to channel the destructive radiation of the infinity stones with just nanotechnology on earthly metals (not Uru or vibranium). His death causes a void, a vacuum of innovation and leadership, and that might be what Doctor Doom would try to fill or exploit as he is also a genius of the same or even greater calibre.
Still want Doom to be his own thing, but if they went the other this is the most acceptable way they could go about it
I just read the second 'edit' and remembered the very last sound from 'Endgame'.... The hammer striking metal on an anvil, way back near the start of everything.
Also to other people complaining about RDJ in this role, y'all do know that RDJ, and the Russo bros were meeting together to hammer out an idea for marvel before all the Johnathan Majors stuff right? And they even took their idea to Feige, and brought him in to workshop an idea. For all we know this was going to be the plan maybe a few more years down the road, now its just been moved up.
You don't bring Tony Stank and the Russos together to work on a single movie, its for something big.
I disagree with you that Doom and Tony being variants is the only way to for the casting to make sense narratively. Not only is there already a precedent of unrelated doppelgängers both in the MCU and real life, it’s also incredibly insulting to the acting capabilities of Robert Downey Jr. to basically imply he can’t act as anyone else but essentially another version of Iron Man. And I say this as someone who’s also somewhat mixed with RDJ’s casting, but for different reasons.
It's possible that the MCU Starks adopted that universe's Victor instead of the child of Amanda Armstrong and/or that in Doom's universe the Starks didn't {exist/adopt}.
