According to this last theory, a demonic creature could be the new threat of Doctor Strange 2.
Filming for Doctor Strange 2 is expected to begin shortly. The opportunity for his star, Benedict Cumberbatch, to take on the role of the Sorcerer Supreme again and for fans to take more on the next adventures of the superhero. If the MCU magician should do everything to stem the damaging effects of the various alternate realities, a new theory relayed by ComicBook would have Shuma-Gorath caused their appearance, previous speculation instead that Loki was the origin of the Multiverse of Madness in Doctor Strange 2. Considered a dangerous and demonic creature, native to an extra-dimensional realm, it will not be surprising to see the monstrous Shuma-Gorath land in Sam Raimi’s film , the director is able to give him a unique horrific aspect while the first shutter was already filming the arrival of Dormammu, a formidable inter-dimensional entity.
The Reddit user behind this theory suggests that Shuma-Gorath will want to reach America Chavez, who is able to open star-shaped portals in order to travel from one reality to another. If the presence of this heroine has not been officially confirmed, the working title of Doctor Strange 2 still suggested her presence. Miss America could thus count on Stephen Strange to protect her. With this in mind, the latter will form a team composed of the Scarlet Witch (Elizabeth Olsen), Wong (Benedict Wong), Karl Mordo (Chiwetel Ejiofor), Clea and brother Voodoo in order to destroy Shuma-Gorath magic. An entry of this Machiavellian force into the MCU that could ultimately match what Kevin Feige meant by horror film when he described the sequel to Doctor Strange’s adventures during San Diego Comic-Con in 2019
