MCU Rumor Roundup: Avengers: Secret Wars Story Details, "Boris" Explained, Ghost Rider's Villain Revealed

We're back with another MCU rumour roundup, and with Spider-Man: Brand New Day in the rearview, all eyes now turn to Avengers: Doomsday and Avengers: Secret Wars

The Cosmic Circus' Alex Perez has shared some intriguing updates today, including details on both those movies and more on what we can expect from Shawn Levy and Ryan Gosling's Ghost Rider movie. From there, we move on to what the deal is with newly leaked images of Avengers: Doomsday's "Boris" and an update on a previous leak.

Be warned that potential spoilers for several upcoming MCU projects follow from this point on...

  • Asked about Monica Rambeau's status for Avengers: Doomsday, Perez shared his belief that we likely haven't heard about plans for Teyonah Parris in the movie "to keep some characters secret," especially as there are some big surprises in store for "the third act." 
  • The report adds that it's likely "Monica and Maria are out and about together on a separate story while the events of Doomsday transpire," though there's a strong chance they're in one or both Avengers movies.
  • Regarding those surprise characters, there are "a couple of Asgardians" set to answer Thor's call to arms, some of whom we haven't seen since Thor: Ragnarok. Could The Warriors Three return? Or two of them, at least? (Sorry, Zachary...).
  • While the plan was for Avengers: Doomsday to open with Spider-Man, Doctor Octopus, and the Green Goblin fighting the X-Men's Deadpool and Wolverine, it's unclear whether that's still the case. However, Tobey Maguire will appear in both that and Avengers: Secret Wars.

  • Addressing Captain America: Brave New World's confusing post-credits scene, The Leader was simply alluding to the end of the world being nigh. As for Sam Wilson, his role in Avengers: Doomsday will be "sizeable." There will also be "a nice little scene for Sam that puts to rest any doubt about who owns the shield or who is Captain America in this movie."

  • Avengers: Secret Wars will feature the "Resistance Avengers," including "the leaders (older, established figures), there’s the newbies (The younger heroes), and there’s the never-before-seen characters (there [are three at the moment]). This group of allies is going to be divided into smaller groups, chasing different stories."
  • It sounds like the Hulk we see in Avengers: Secret Wars will be the same as/similar to Thor: Ragnarok's take on old Jade Jaws.
  • Doctor Doom will be Avengers: Secret Wars' main antagonist, but he'll also be joined by "certain characters" who side with him because "they are all convinced to serve him until they're freed."

  • Asked about plans for Tom Holland's Spider-Man to get his hands on the Symbiote in Avengers: Secret Wars, Perez said that Marvel Studios is mulling over various options, including "an original take" and versions that are similar to what we saw in Spider-Man 3
  • When it comes to the Scarlet Witch, she's set to have an "important role" in Avengers: Secret Wars, given that "her power is a key element to how Doom's Battleworld gets made." Everything we've seen from the Maximoff family could be key as the Multiverse Saga nears its end.

  • Over to the Ghost Rider movie starring Ryan Gosling, and it sounds like we can expect Sacha Baron Cohen to reprise his Ironheart role as Mephisto and that Johnny Blaze will have been serving as the Spirit of Vengeance for a while when the movie begins.

  • Back to Avengers: Doomsday, and we have some intriguing insights into why "Boris" (Doctor Strange) looks the way he does as one of Doom's followers...
  • We've also confirmed that this is a legitimate, albeit AI-enhanced, image from Avengers: Doomsday. It's after the Sentinel battle, and at this point, Doom has taken Steve Rogers.

Interesting... sounds like a lot of things might change from those earlier plot descriptions, especially after the substantial reshoots. More stuff added, perhaps some things taken out, or re-worked / re-ordered...

@Jackraow21 - that's gullible. It's more likely most of the rumors are lies for engagement

@Jackraow21 - If something doesn't happen I'll take it as the rumor was a lie not that Marvel changed it. Like you said rumors on rumors. Too many for even a few to be correct.

Of course Disney will triple down on Sam as Cap no matter how badly it fails. He was a great Falcone but he’s no Steve. The only way another movie with him as Cap goes forward is if they load it with characters fans actually want to see. A true solo outing is off the table. Same with the “Young Avengers”. Fans will come see Secret Wars for their favorites and it will make money, but when they try anything with those characters alone it will be like throwing a hundred million in a paper shredder

@Bucky74 -

Yep. FalCap and the Young Avengers push are really bad ideas.
Bucky74
Bucky74 - 8/9/2026, 12:14 PM
@DocSpock - Complete failures, but Disney will convince themselves that “this time” they will catch on with fans not matter what. And they’ll maybe throw Spider Man in a cameo in Young Champions/Avengers or whatever hoping it get butts in seats
DocSpock
DocSpock - 8/9/2026, 12:32 PM
@Bucky74 -

FalCap, Photon, Ms Marvel, Wonder-Man, Valkyrie, & Ironheart were not inserted into the MCU because they would make great MCU headliners.

It was about more racial representation, which is and should be a good thing. The problem happens when they shove them in just to meet quotas and handle the characters badly. The first BP movie is a great example of doing things right. The Marvels is a terrible example of doing it wrong.

They do a very big disservice to these fine minority actors when they use them badly in lousy movies/shows.

Mackie was in excellent in the 4 Russo MCU movies. But the FalCap/WS show and the last CA movie were terrible.

@DocSpock - 💯
Bucky74
Bucky74 - 8/9/2026, 1:32 PM
@DocSpock - Agreed. Marvel already had excellent minority characters like Blade, Storm, Black Panther (the MALE BP) etc. They don’t need to race swap classic heroes. Iron Heart was at least an attempt to make an original minority character, but she was an unlikable character who boiled down to her character being set up as “Black female Iron Man but smarter than Tony” so she was a fail. Not every character is going to be a hit. Blade could have been done as an original Marvel character today and he’d be a huge hit because he’s a badass Daywalker and a cool character. It has to be organic
DocSpock
DocSpock - 8/9/2026, 2:01 PM
@Bucky74 -

So sad they totally failed on Blade. I wish they could convince Coogler to tackle that great character.
Bucky74
Bucky74 - 8/9/2026, 2:13 PM
@DocSpock - Yeah he’d kill it. Ali is an excellent actor too, but I think he’s too old now to first start a new franchise. Start fresh with a younger guy. How hard can it be to write an awesome Blade movie? The supposed script that read like Thw Rais sounded great but they just did that with Punisher Last Kill so that won’t work. I want Blade in Midnight Sons too
Bucky74
Bucky74 - 8/9/2026, 2:13 PM
@Bucky74 - “The Raid”
Hobmoblin
Hobmoblin - 8/9/2026, 6:51 PM
@DocSpock - they only tried Muslim directors on Blade. That's the actual real race based bad casting that flies under the radar. My guess is Ali is Muslim? If not I don't know why. But they only ever hired Muslim directors for that. Could work but if they aren't working maybe just hire someone who can pull off the jobs that's needed.

@Hobmoblin -

Well, if Hollywood did anything correctly with no blatant agenda showing, everyone would be surprised.

It’s wild the Falcon as Cap movie did so bad and they’re still hung up on it, or so it seems. A Young Avengers movie will hold little interest for most. They need to just accept people want the big characters and after so many superhero movies successes like Ant-Man and Guardians are going to be very hard to come by. X-Men will likely keep them in business, post Secret Wars and Ghost Rider with Gosling in it could do well. Any of these side character ideas, however, for feature films will just be wasting money. Their tv debuts alone prove that.

@Astroman - 2025 was the MCU's worst year ever and they just put all those characters front and center in their big Avengers movie. wtf are they thinking. Are they even thinking?!
Hobmoblin
Hobmoblin - 8/9/2026, 8:27 PM
@Astroman - only being into the most popular characters? Are you even a Marvel fan at that point or just a frontrunner/follower of whats trendy?

What's real is it needs to be deserving characters nobody matter how obscure. With your logic the MCU wouldn't exist because Iron Man and Thor were C listers at best and Cap was considered unmarketable after the Iraq War.

Loohnutick - 8/10/2026, 12:40 AM
@Hobmoblin - eh, no. Sorry, nobody wants to see Yelena, Red Guardian, Steve Rogers in a black shirt, etc leading the charge against Dr. Doom. Which is why I'm on team MCU hard reboot (or drastically change the leaders of the MCU). They're writing themselves in a corner killing off heavy hitters like Cap, Iron Man, Black Panther when these events is where they should be. They did their farewell movie with Black Panther 2 (amazing movie btw) but making a huge turn and bringing back a T'Challa shows they know how much the IP is worth.

Hopefully they follow with rebooting Iron Man, Cap, maybe bring in Hank and Janet in their prime in time for the X-Men events, cus if we get an Avengers vs. X-Men in the future with a bunch of Z-list Avengers, it's gonna be lame and a waste of potential.

Hopefully Mephisto isn’t the only villain, they should include Vengeance or The Orb.

'Boris' is clearly Victor Von Doom's mentor and most loyal subject Boris Karela. You can see him in the Dr Doom episodes of the old 'Spider-Man' and 'Spider-Man and his Amazing Friends' animated series from the 1980s.

@Eagleheart - he’s also from the comics.

It could be him or likely just a nod to the character.
ObserverIO
ObserverIO - 8/9/2026, 3:15 PM
@Eagleheart - That could be interesting if they merged his character with his mentor in the comics, the Marquis of Death. But I still think this is a red herring to throw us off the scent and it's Strange.

There is only one round up that has everyone all hot and bothered. We want to know more about the Jimmy Olsen TV series. There is nothing else that people are thinking about.

Those ideas are [frick]ing dogshit.

Half the crew on here have been conditioned to fawn over anything that gets released even if it is DEI Dogshit.

The hivemind ridiculousness will love RJD as Tony Stark while struggling with the cognitive dissonance being forced to defend Boss Betch RiRi shitting on him in a token ass show that should have never been made.

REBOOT THIS WHOLE [frick]ING ABORTION

Falcon in the comics becomes Cap (accurate)Valkyrie portrayed as a African American (not accurate) but idiot fanboys on this site want it both ways and like neither....

....stupid!

@incredibleTalk - And it sucked in the comics too and was only down for one reason. The Ex Burbaker Bucky Cap run was well done but even that doesn’t work. Steve Rogers is Captain American like Bruce is Batman. Changing those iconic characters will always fail
incredibleTalk
incredibleTalk - 8/9/2026, 2:31 PM
@Bucky74 - Idiot fanboys didn't want to see Robbie Reyes as Ghost Rider either...they wanted the "white" Ghost Rider instead on AOS!!!

Bucky74 - 8/9/2026, 3:05 PM
@incredibleTalk - "White" is a stupid take. The OG bike riding bad ass is most people's clear favorite. I actually liked Luna's take in AOS, but Johnny Blaze is the classic take and will always be more popular. If they made a "White" Blade, we'd all complain too. It's not the character.
