‘Spider-Man 3’ Could Introduce the X-Men in a Post-Credits Scene: Inside the New MCU Theory

Ever since the Fox/Disney merger, rumors have been running rampant concerning the X-Men’s introduction into the Marvel Cinematic Universe. How will the mutants join the existing landscape? Where have they been this whole time? How will the present MCU timeline give rise to an entire mutantkind that has yet to be mentioned in any capacity?

Who will join first, and why will they be essential to the established Avengers? A new theory – from the Cosmic Wonder (relying on an enthusiasts’ foresight and established Marvel leaks) — suggests that the X-Men may come to play in Spider-Man 3. The theory suggests than an on-the-run Parker will look toward Doctor Strange for help, leading him to Professor Xavier. Let’s break down the theory, starting with where Spider-Man: Far from Home left off. 

‘Spider-Man: Far From Home’ criminalized Parker, and his predicament will remain the same in Sony’s ‘Morbius’ 

At the end of Spider-Man: Far From Home, a deceased Mysterio manages to reveal Spider-Man’s identity and criminalize the web-slinger as a murderer from beyond the grave. Thus, the next time fans see Parker, he will be a fugitive on the run — from both the villains wanting to end him, as well as the cops wanting to place him beyond bars. 

In the Morbius trailers, Spider-Man’s current predicament in the MCU comes to the surface, as his image on a wall features the word “murderer” spray-painted on top of it, and a bus advertisement reads “Where Is Spider-Man?” With the two universes connected, the Sony Spider-Verse is alluding to the MCU and, more specifically, to the false accusations that have come to characterize Peter Parker. Meaning, when the third Spider-Man movie comes to silver screens, Parker will be on the run — likely unable to see his friends and family — fighting foes and avoiding the police — all while attempingt to clear his name. 

The theory starts from this origin point. Spider-Man will need help, and he may look toward a man who resides in New York who is capable of helping him — a man capable of wielding the mystic arts: Doctor Strange. 

Will Doctor Strange introduce Parker to Professor Xavier, who will keep him safe at Xavier’s School for Gifted Youngers? 

The Cosmic Wonder goes on to explain the theory, noting that Parker will be on the run and in danger, which will bring him to Doctor Strange by the end of the movie (or in a post-credits scene). 

Doctor Strange — who is allegedly forming The Illuminati in the Multiverse of Madness (a group Professor X is intimately attached to) will bring Parker to Professor Xavier. Xavier can use his powers to shield Parker from the world — to keep his location hidden. 

Parker can also socialize with other gifted youngsters at the school. He will likely need some new friends following his revealed identity and an inability to see his family and school peers.

Parker will also be able to further groom his powers and learn what it means to be a hero and a leader under Professor X — one of the wisest men whose leadership stands in a league of its own in the Marvel comics. Thus, Spider-Man will be ready if and when he has to lead the New Avengers in a future MCU mash-up. Spider-Man becoming a leader has been suggested in multiple leaks, and who better to groom him for the role than Professor X?
