The Cosmic Circus' Alex Perez has shared some new MCU rumours, and while we'd suggest taking them with a pinch of salt—as usual, there's an element of educated guesses mixed in with possible scoops here—there's a lot to unpack.

Starting with Avengers: Doomsday, Perez says that Sue Storm's "experience in diplomatic relations with dignitaries will come in handy" while dealing with Namor the Submariner. However, her role in the movie may be far more impactful than that. 

"Sue’s arc is a very interesting one to see develop. Mainly because Sue will be one of those few characters who's going to have a personal relationship with Doom and will understand what his motivation is," the insider explains. "And it’ll put her in the difficult position of trying to sympathise with her friend while also trying to protect her family." 

At least part of the movie's reshoots revolved around adding an action sequence with Sam Wilson's Captain America, and Perez claims to have learned more about who Doctor Doom's three Latverian Witches are not.

"The Ancient One and Death are definitely not the Latverian Witches," Perez writes, debunking those reports. "Aside from the fact that the Ancient One is dead, Death simply doesn’t care, and she’d never willingly serve under someone. As for a hint under the identity of the Latverian witches, most of their identities have technically already been revealed."

He cryptically adds, "Who’s to say that these witches are who they say they are and aren’t actually just playing a very elaborate trick?"

Moving on to Avengers: Secret Wars, the scooper suggests looking to Jonathan Hickman's Avengers and Secret Wars comics for insights into who will be among the brainwashed barons serving Doctor Doom. He's also heard that Agatha Harkness is set to return in the movie. 

Alien: Romulus star David Jonsson takes over as T'Challa (or Toussaint/T'Challa II) in Ryan Coogler's Black Panther 3, but how has he been aged up? Perez puts it down to "universe-reshaping shenanigans."

Finally, Rogue vs. Captain Marvel is "possible" for the post-Secret Wars MCU, Billy Maximoff/Wiccan will get a chance to shine in the Multiverse Saga finale, and VisionQuest will set the stage to assemble the Champions. 

Again, all of these claims are best taken with a pinch of salt. Still, it won't be long until these MCU projects come along and we find out whether there's any truth to these and the many other rumours currently doing the rounds online.

Avengers: Doomsday is set to be released on December 18, with Avengers: Secret Wars scheduled to arrive on December 17, 2027.

Ancient One and Death never seemed likely to me.

Disney still trying to build up the young avengers, and although I’m sure there are tons of fan boys who won’t agree, Wiccan and Speed are D level characters no one cares about.

Just use Secret Wars to recast, and let’s get back to work with the big guns. We’ll finally have the X-Men in the MCU, now’s not the time to move on from Tony and Steve etc.

Then all that’s left is to buy Sonys movie division, and give us a proper Spider-Man vs Venom movie, without other cameos.

Crazy I know, a Spider-Man movie carried by Spider-Man.
