This week, we got what appears to be our first official look at the character design for Robert Downey Jr.'s Doctor Doom via some promo art, and we now have some more details on the powerful villain's nefarious plans for the MCU thanks to the first synopsis for Avengers: Doomsday.

Unveiled along with a new banner at the Walt Disney Marketing Expo in Shanghai, the logline reads:

"Doctor Doom has officially arrived in the MCU. This villain, a master of cutting-edge science and powerful magic, will unleash a cascading crisis across the entire multiverse."

While this doesn't tell us too much, it does confirm that Doom will utilize magic and technology. As for this "cascading crisis," rumor has it that Victor Von Doom's mission will involve him hunting down those who were responsible for causing the Multiversal incursions, one of which resulted in the deaths of his wife and child.

If this is the case, it sounds like Doom will cause even more damage in his quest for vengeance.

Check out the banner below, along with a new fan-made poster for Doomsday.

A new banner featuring Spider-Man and Doctor Doom and a first synopsis for AVENGERS: DOOMSDAY has been released during the Walt Disney Marketing Expo in Shanghai:

Avengers: Doomsday and Avengers: Secret Wars were recently hit with significant delays, 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.

Holy hell is than an official image with the Ultrons and Thanos and Sentinels?

ProfessorWhy - 9/13/2025, 2:23 PM

@Thing94 - no

Jackraow21 - 9/13/2025, 2:24 PM

@Thing94 - I wish! It’s fan made.

RegularPoochie - 9/13/2025, 2:27 PM

@Thing94 - if it is, that's Doom's Avengers

RegularPoochie - 9/13/2025, 2:36 PM

@Jackraow21 - damn, that would have been bonkers. I actually still like the evil/dark Avengers, if it's true.

Mrcool210 - 9/13/2025, 2:31 PM

I honestly think doom will be pretty well characterized. They know he's been royally [frick]ed at least 2 times (3 if you count the 94 movie) so similar to the fantastic four I feel like getting doom right is one of the biggest priorities with these movies.

TheVisionary25 - 9/13/2025, 3:09 PM

@Mrcool210 - yeah though I’m interested to see their specific take on Doom and how RDJ portrays the character

Even with all the hubbub around his casting , he’s still the reason for most of my interest/excitement around the film.

WruceBayne - 9/13/2025, 2:34 PM

I hope they go full comic book and let the Sentinels look like that and hopefully they’re not a big Iron Man suit.

RegularPoochie - 9/13/2025, 2:38 PM

@WruceBayne - After Galactus I'm pretty sure they will. Feige recently talked about this comicbook accurate thing, when he talked about the X-men

WruceBayne - 9/13/2025, 2:41 PM

@RegularPoochie - I’m all for it. I know we had that promising set photo of that comic accurate Sentinel leg and I hope that it gets better from there.

RegularPoochie - 9/13/2025, 2:48 PM

@WruceBayne - exactly

RegularPoochie - 9/13/2025, 2:52 PM

@WruceBayne - Feige also said in that he wanted comic accurate suits for them in fox-men, but they went with those that we got, so basically p-parody suits

Apophis71 - 9/13/2025, 3:36 PM

@RegularPoochie - Feige didn't have much creative input when working on the Fox films, least not in the early days so not his fault if they didn't go with what he wanted in those. I'm sure he wasn't alone amongst all those working on them that wanted comic accurate but did their job anyway when those with the power to decide opted otherwise. I mean the first one he had about as much power as a political intern str8 out of Uni would in determining government policies. Once he DID start climbing the ladded enough that his voice would have weight we got First Class which was a big improvement on what went before but only so far they can deviate from the prior films when those are supposed to be what they will end up wearing/looking like.

We've mostly had close to comic accurate in the MCU, even if oft more ultimate comics accurate and the like rather than original 616 outfit choices and over time progressively gotten closer and closer to classic 616 looks in the costume dept most the time.

SpiderParker - 9/13/2025, 2:37 PM

Marvel will do a better Doomsday than DC.

DarkeyeZ - 9/13/2025, 2:39 PM

So he will have Science AND Magic? Dope. I was afraid that we were going to get a nerfed Doctor Doom. His last 2 portrayals on screen were....less than Ideal (that is the nicest way I could put it).

Bucky74 - 9/13/2025, 2:42 PM

I thought Doom was trying to save the multiverse. That suggests that he is the cause of the problem.

Vigor - 9/13/2025, 3:08 PM

@Bucky74 - sometimes you have to destroy, to fix

Bucky74 - 9/13/2025, 3:42 PM

@Vigor - That was sort already done withThanos

Vigor - 9/13/2025, 3:59 PM

@Bucky74 - so was trying to save the universe

AnthonyVonGeek - 9/13/2025, 2:42 PM

I hope there’s gonna be flashbacks to Dooms past , if not it seems kinda lazy that they’re gonna have Doom show up all powerful not show us his rise to power.

TheVisionary25 - 9/13/2025, 2:43 PM

The rumor of RDJ’s Doom possibly hunting down people he feels are responsible for the Multiversal incursions which led to the death of his wife and child is interesting…

Victor having a family reminds me of the take in Iron Man:Armored Adventures where he was a member of the Latveria royal family who did an experiment that killed his mother & wife to be while also scarring his face (that version also had no ties to the FF).

Anyway , I just hope we finally get a truly good or great version of the character since he hasn’t had that in live action even with the controversy around RDJ’s casting…

I’m not a big fan of Julian McMahon’s version of the character from the Tim Story films and the less said about Fant4stic’s version , the better (I do enjoy Joseph Culp’s from the unreleased 1994 film just for his sheer theatricality from the clips I have seen).

epc1122 - 9/13/2025, 2:51 PM

@TheVisionary25 - why didn’t you like Julian McMahon version?

TheVisionary25 - 9/13/2025, 3:04 PM

@epc1122 - he was alright

I thought McMahon did well and he had fun dialogue & moments but it was just the lack of depth

He felt like an inferior version of Raimi’s Norman Osborn.

epc1122 - 9/13/2025, 3:10 PM

@TheVisionary25 - gotcha. I wasn’t sure if it was because it wasn’t comic accurate enough which I think generally you don’t have a problem with. I’m excited for Robert Downey’s take and curious how they weave all the stories. I’m pretty excited for the future of marvel and after this, they’ll reboot 👍

TheVisionary25 - 9/13/2025, 3:15 PM

@epc1122 - yeah , comic accuracy or inaccuracy doesn’t really bother me

There are so many versions of these characters across media and even in the comics that o think it’s valid for the creatives to find& take inspiration from the ones that they find interesting and then leave it to us to see if we agree or not.

I think the future for both the MCU and DCU seems exciting , it’s just unfortunate some others don’t see that.

epc1122 - 9/13/2025, 3:32 PM

@TheVisionary25 - yeah, the creators of these movies and tv shows have such a tough job where they have to make these versions close enough to the comics where the die hard fans are happy yet bring enough new to bring the general audience in. Some ideas work and some don’t but it’s nothing to be inherently offended by. Which upcoming project are you looking forward to most?

ModHaterSLADE - 9/13/2025, 2:54 PM

So Doom is basically using his powerset from the comics...Cool.

CrimsonComet40 - 9/13/2025, 3:08 PM

So...a Crisis On Infinite Earths?

Scarilian - 9/13/2025, 3:16 PM

The trouble is... why should we care about Doctor Doom? They have done zero set-up other than a rushed post-credit of Fantastic Four. We know nothing about him.

Thanos had build-up and hype of himself and his potential powers over the course of multiple movies and even appearances and people discussing him prior.

Doctor Doom is going to come out of virtually nowhere with zero hype for most the audience as the last iteration of the character was Fant4stic and while I enjoyed the 2005/2007 version that was barely Doctor Doom but it's how the audience could view the character.

I think Doomsday is a disaster, they know it, which is why they have shifted from trying to get people invested in the heroes to trying to get people to be invested in Doctor Doom. Remember how they were trying to claim this character or that was the leader of the Avengers in this? Now they've dropped trying to draw attention with all that because even the X-Men wasn't enough to get people to care.

epc1122 - 9/13/2025, 4:10 PM

@Scarilian - I don’t think every villain needs some huge setup. Downey signed on for the next two movies so I’m sure they’ll get into some of his backstory. The big draw is the actor and how it affects the other characters. I’m really curious how Thor is going to react to doom/Downey. Russia have a good track record with marvel, I’m hoping for a grand finale of this universe that i hope will lead to a reboot and get to see Iron man and captain America again. I think Thor is going to die and he won’t be back in the new universe for awhile. Well, it’ll be the next two avengers and then he’ll die in Thor 5.

MyCoolYoung - 9/13/2025, 3:19 PM

My guess is the crisis is that Doom is somewhat right, even if his methods are questionable, like Namor working with the Cabal, which is a really messed up conundrum.

MuadDib - 9/13/2025, 3:31 PM

Super unpopular opinion: Dr Doom is overrated.

Top that off with a bad casting in RDJ, the only thing drawing me to this movie is the ensemble cast that includes everyone ever and the lead up to Secret Wars.

Secret Wars is the real crown jewel as it’s the secret weapon Marvel has to reset things and recast roles and lay a new foundation for the future of the MCU

Beyond that, this whole event screams desperation. They haven’t had a billion dollar hit in years and superheroe fatigue is a real thing. That’s why this is gonna be a huge as it is, bc it’s all they can do to draw the audience back in.

Kinda sad in a way.

Here’s hoping I’m wrong and it turns out to be the best marvel movie yet

But I’m not holding my breath
