Marvel Studios has been diving head-first into the multiverse with projects like Loki, Spider-Man: No Way Home and now Doctor Strange in the Multiverse of Madness. Multiverse of Madness focuses primarily on the multiverse and features some pretty cool cameos from some surprising Marvel heroes. During the film we’re introduced to iconic Marvel group from the universe designated 838, the Illuminati, and the line up featured Captain Carter (Hayley Atwell), Captain Marvel (Lashana Lynch), Black Bolt (Anson Mount), Professor Charles Xavier (Patrick Stewart), Mr. Fantastic (John Krasinki) and Baron Mordo (Chiwetel Ejiofor). One major thing that fans have noticed was the lack of the Avengers in that universe, and as it turns out, there’s a very specific reason for that. During a recent interview with Empire Magazine (via The Direct), Marvel Studios producer Richie Palmer revealed that the Avengers from that universe retired due to Tony Stark successfully creating Ultron.
