Marvel introduced us to the Illuminati in Doctor Strange in the Multiverse of Madness. But here is the main question, what happened to the Marvel Universe’s Avengers?
Earth-838, as it is known, has extremely powerful heroes who easily defeated Thanos. Baron Mordo (Chiwetel Ejiofor), Captain Carter (Hayley Atwell), Black Lightning (Anson Mount), Captain Marvel (Lashana Lynch), Reed Richards (John Krasinski), and Professor Charles Xavier (Patrick Stewart) comprise the Illuminati. But we also know what happened to the Avengers.
It reveals that Tony Stark was successful in protecting the world with the Ultron shield, according to Marvel Studios producer Richie Palmer. As a result, the Avengers withdrew gradually.
“Yes, we believe Wanda had some children and was somewhat withdrawn on Earth-838.” She was content with her life with her family and didn’t see the need to prioritise being a superhero.
Perhaps because of the Illuminati, perhaps for other reasons. But in this world, Ultron appeared to function as Tony Stark intended in Avengers: Age of Ultron. Tony was attempting to convince the Avengers to retire in that film because it was: A suit of armour around the world.
So imagine a world in which Tony figured out Ultron and it worked, and he said, “Hey, whoever wants to retire and go home can.” The Illuminati then appeared behind the scenes, pulling strings, but I believe it’s just a better world for whatever reason, and Wanda was able to go and have the life she deserved.”
Because the Illuminati have been annihilated and the Avengers are half retired, the future of Earth is somewhat complicated.
So Ultron could come from there and conclude that the only way to protect humanity is to destroy it… Who can say? They might tell us later.
