The Marvel SDCC panel revealed a huge change coming to the Marvel Cinematic Universe that will send shockwaves through the entire fandom. Avengers 5 finally receives a new title and will be calledAvengers: Doomsday, but surprisingly, that is not the biggest piece of news to come from the panel. That honor goes to the reveal that Doctor Doom is coming to the MCU and will be played byRobert Downey Jr.
Yes,Iron ManactorDowney Jr. will be finally making his return to the Marvel Universe, but as one of the franchise’s biggest antagonists.

However, while the previousAvengersoutings featured thelikes of Robert Downey Jr.’s Iron Man, Chris Evans’ Captain America, Scarlett Johansson’s Black Widow, Chris Hemsworth’s Thor, and Mark Ruffalo’s Bruce Banner/Hulk, theDoomsdayroster is currently unknown, and Marvel boss Kevin Feige has said weshould not expectto see every hero in the next sequel.
“I rarely speak in absolutes like that, right? The notion of never ever seeing somebody again, we’ve got Tim Blake Nelson in a movie coming up next year, right? So I never talk in absolutes like that. But the truth is, you know, we’re going to tell a story in these Avengers movies, and there won’t be room for 100,000 characters in it. So choices will have to be made, that’s for sure. But that doesn’t mean you won’t ever see anybody ever again.”
