Both Wanda and her brother Pietro debuted in X-Men comics as supervillain members of the Brotherhood of Mutants, under the tutelage of their father Magneto. Interestingly, Charles Xavier won't be the first character from the X-Men comics mythology to be a part of the MCU. But the biggest name on the list has to be Professor Xavier, since his addition to Doctor Strange in the Multiverse of Madness would signal the arrival of the X-Men in the MCU. Meanwhile, Balder the Brave is a character from Marvel Comics who is an Asgardian deity, as well as a half-brother and close friend to Thor. Mordo's (Chiwetel Ejiofor) addition would be a surprise, since he appeared to have turned to the dark side at the end of the first Doctor Strange movie, and was expected to become a full-fledged villain in his next appearance in the MCU.

Captain Carter (Hayley Atwell) showed up in animated form in Marvel's What If.? series an an alternate world version of Captain America. Monica Rambeau (Teyonah Parris) was Wanda Maximoff's ally and budding superheroine in WandaVision. Three of the names have already shown up in the MCU. According to the version of the Illuminati that will show up in Doctor Strange in the Multiverse of Madness will comprise of Professor Charles Xavier, Captain Peggy Carter, Balder the Brave, Monica Rambeau, and Mordo. Rather than acting as an outright team, the heroes prefer to work behind the scenes through secret pacts and the exchange of important information to preemptively defuse world-threatening events.

In Marvel Comics, the Illuminati is composed of some of the greatest and most knowledgeable minds in the superhero community. But it could bring a key player from the X-Men Universe into the Disney era of Marvel superheroes.

The reveal is that a new superhero team called the Illuminati will be introduced in Doctor Strange in the Multiverse of Madness, a rumor we've heard before.

A Twitter user named who claims to have inside information about the project has leaked a massive possible spoiler for the movie. Of all the MCU movies gearing up for release in the coming year, Doctor Strange in the Multiverse of Madness promises to be one of the most significant in terms of affecting the future of the Marvel Cinematic Universe.
