Avengers: Doomsday rumor reveals shocking ally for Robert Downey Jr’s Doctor Doom

Robert Downey Jr’s Doctor Doom will make his MCU debut inAvengers: Doomsday, and he may enlist the help of a familiar sorcerer, according to a new rumor.

Once upon a time, everyMarvelfan knew Thanos was coming and that he wanted to gather the Infinity Stones for his gauntlet, with the threat (and aftermath) of his universe-halving snap being the catalyst for Avengers: Infinity War and Endgame.

The same can’t be said for Doomsday andSecret Wars. All we know is that Doctor Doom will be involved, Downey will play him and his likeness to Tony Stark is part of the story, as well as the stars who were announced as part of the movie’s livestream earlier this year.

The assumption is that it’ll have something to do with the multiverse, with Doom trying to save (or avenge) his world from an incursion – which is where one hero could come in.

During an episode ofThe Hot Mic, insider and reporter Jeff Sneider said he’d “heard that Doctor Strange is with Doom… he’s on that side of things.”

This also comes afterThe Beyond Reporterclaimed that not only will Strange work with Doom, but he’ll be considered a villain. Alex Perez fromThe Cosmic Circusalso reported that Strange will be tasked with fixing an incursion in Doomsday, “by any means necessary.”

“This would be a good time to remind everyone that the flow of time is different in the Dark Dimension since it is basically nonexistent. So, even though it’ll have been 3.5–4 years since Stephen Strange has been on Earth, imagine how much time would have passed in the Dark Dimension?” he added.

Remember, Strange was whisked away by Clea (the daughter of Dormammu, played by Charlize Theron) because his actions triggered an incursion – in layman’s terms, the impending collision of two Earths caused by multiversal shenanigans.

That’s important context, considering another Cosmic Circus report saidDoom sees “the incursions that are happening as a danger to the multiverse, and he wants to put a stop to it using a young Franklin Richards.”

“He sees himself as the hero in this story and will do whatever it takes to make sure he stays on top,” it added.
