Doctor Doom (Robert Downey Jr.) will put the MCU on notice when he returns in Avengers: Doomsday after making his debut in The Fantastic Four: First Steps' post-credits scene, and it sounds like he is going to have some formidable backup.

Possible spoilers follow.

Previous rumors have claimed that Doom will have a team of his own in Doomsday, and the leaked concept art (though the Russo Brothers denied that it had anything to do with the upcoming Avengers movies) that circulated online earlier this year showed the masked villain alongside several other characters, including Doctor Strange.

During this week's episode of The Hot Mic, Jeff Sneider said he heard that Benedict Cumberbatch's (former) Sorcerer Supreme will be "working with" Doctor Doom in Avengers: Doomsday.

We wouldn't be at all surprised if this was accurate, but will it be our Strange or a Multiversal variant? We have heard that Doom will use the fact that he so closely resembles Tony Stark to his advantage by infiltrating other realities with his group of "evil" Avengers variants, but this wouldn't necessarily mean that Earth 616's Doctor Strange won't decide to change allegiances.

At the end of Doctor Strange in the Multiverse of Madness, Clea (Charlize Theron) shows up and recruits Strange to investigate the incursions that have begun to occur around the Multiverse. If Doom's mission is indeed to prevent these incursions, hero and villain may find themselves forming an unlikely alliance.

What do you make of this rumor? Let us know in the comments section.

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.

Yeah, makes sense if both are figuring out what to do with the Incursions

McMurdo - 8/22/2025, 2:55 PM

@movieguy18 - makes sense if your going to continuing botching the characterization of your strongest characters. If these rumors are accurate, this story is gonna suck. Blaming Steve Rogers and Stephen Strange for the apocalypse of the multiverse is boring.

KaptainKhaos - 8/22/2025, 2:05 PM

None of this matters, just show us Doom's costume, that's all I care about

STOP GIVING THESE HACKS A PLATFORM

TheVisionary25 - 8/22/2025, 2:20 PM

Interesting if true…

Given it’s Secret Wars , I could see them heading the Sheriff Strange route with Stephen having made a deal with Doom to save the multiverse but eventually turns against the latter.

Just imagine the reaction when the heroes see Strange is back but has allied himself with their latest threat?.

Bucky74 - 8/22/2025, 2:23 PM

We want Strange Vs Doom, not a team-up. Doom's magic abilities rival Strange's and his tech and intellect make him OP. There is no reason to team him with Strange.

braunermegda - 8/22/2025, 2:53 PM

@Bucky74 - just wait, dude. First this is a rumor from Jeff snider, it'd be more reliable hear my dog back. Second, even if it turns out true, its OBVIOUS they'll fight, its just a matter of time until Doom shows his real self. So relax.

McMurdo - 8/22/2025, 2:58 PM

@Bucky74 - This is what the McFeely does. He didn't want to write for Hulk, so he made Hulk a coward who is too afraid to rematch Thanos. Dr. Strange is powerful and because he's powerful, you can't just sideline him. Thus, you make him a "villain" and blame the end of the world on him. Supposedly they're doing the exact same thing with Captain America.

@Bucky74 - Triumph and Torment adaptation in the future. Would be nice.

OT - I’m shocked that we haven’t gotten an article on this yet. This site would have pages and pages of arguments about it.

Many of us have said this for years. It’s nice they are finally admitting it. Not sure they are going to make the needed changes, but admitting the reality is the first step towards recovery.

@mountainman - bud, I'm sorry to break this to you, but trying to please men from 13 to 28 is not going to end with good content.

mountainman - 8/22/2025, 3:24 PM

@braunermegda - Where did I claim that Gen Z men have appropriate taste? The point is that Disney is finally openly acknowledging that they have mismanaged Star Wars and Marvel. Couldn’t care less that their PR spin is to blame it on Gen Z wanting new things. The largely Millenial and Gen X audience that gave them much more successful movies last decade has stopped supporting at the same levels.

OrgasmicPotatoe - 8/22/2025, 3:32 PM

@mountainman - The denial can only go for so long, after that, they just quietly walk it back. For how many years have we heard the infamous 'if you don't like it, don't buy it' ? Well, it turns out that people 'not buying it' isn't a financially viable solution. Who could've thought ? The same thing happened with the vaccine - It was a godsend miracle cure that everyone without exception should inject without question- until after many suspicious deaths and exploding hearts left and right, it's now on a 'see if it's safe for you' basis. Turns out when people are suspicious about being told to buy into something without question, they're often right. Question everything.

It's the same old, tired, repetitive song and dance, and there are fools out there impatiently waiting for it to start over again.

mountainman - 8/22/2025, 4:03 PM

@OrgasmicPotatoe - Different situations but the same gaslighting occurred for sure. Brands can make pivots and be successful. They can even expand their appeal to new audiences. But it generally isn’t smart to try to pivot away from a core audience when you are doing well.

hue66 - 8/22/2025, 2:30 PM

They'll likely team up for the common goal re. incursions and become enemies when Doom reveals his selfish agenda.

TheLobster - 8/22/2025, 2:40 PM

That was pretty evident from the concept art that leaked and I’m personally here for it. If we can’t have Strange being the main character (akin to Tony or Steve in the Infinity Saga) in the Multiverse Saga then this is the second coolest route IMO

McMurdo - 8/22/2025, 3:05 PM

@TheLobster - Dr Strange has been thoroughly botched as a character since No Way Home. Now any time anything goes wrong they just blame him. zZzZz

lazlodaytona - 8/22/2025, 2:50 PM

That's still a heck of a lotta big names to have to work with. I know the Russo Bros are good, VERY good ...

.... here's hoping they pull it off as they usually do!

FrankenDad - 8/22/2025, 3:16 PM

Wonder if they’re already leaning into the post Blood Hunt storyline where Doom gets Strange to hand over the title of Sorcerer Supreme to save everyone (from the incursions in the MCU as opposed to a vampire takeover in the comics).

MyCoolYoung - 8/22/2025, 3:21 PM

I think this is a guess based on that Secret Wars concept art that was released. Maybe he works with Doom because he’s just like Doom in believing they’re the savior. But if he knows Doom has nefarious intentions and still works with him, it would walk back the character development from Multiverse of Madness.

TheVisionary25 - 8/22/2025, 4:05 PM

@MyCoolYoung - how would it walk back that character development?.

Stranges arc to me in that besides resolving his feelings for Christine was about always having to be the one in control or “holding the knife” which he grows out of when he gives America that control to fight for herself.

Honestly thinking about it now that if it this happens then it might be him walking back that development either way since he would kinda be making decisions for others again I feel.

Granted growth is not linear and people can backtrack but still

MyCoolYoung - 8/22/2025, 4:47 PM

@TheVisionary25 - I guess that is his arc. You know, not having to do things his way and, in the end, messing things up from stubbornness.

But I guess the wrinkle could be him trusting Doom's plan and not taking control of things believing in Doom's plan. That could work.

SuperiorHeckler - 8/22/2025, 3:48 PM

Doc Strange was in fact Doom's right-hand man for Hickman's SECRET WARS 2015 series. So, since the Russo Bros are obviously leaning into that interpretation for inspiration, it makes sense to have Stephen seemingly side with Victor. 🤓
