10 Theories For How Deadpool Could Join MCU
4. Deadpool Ends Up In The Wrong Multiverse
At the end of Deadpool 2, the Merc With a Mouth had a little too much fun toying with Cable's time-travel device, killing Ryan Reynolds for considering starring in Green Lantern, bringing his girlfriend back from the dead, and even killing baby Hitler in one particularly controversial post-credits scene.
While this was clearly meant to be just a series of throwaway jokes, why not find a way to give them some consequences? Perhaps Deadpool's constant toying with the timeline ultimately lands him in a world unlike his own: the Marvel Cinematic Universe. This fish out of water concept is a familiar one, but would take fans on a journey through this universe through the unique eyes of Wade Wilson.
Hell, if Marvel Studios really wanted to commit to the gag, it could be revealed that his time-travel shenanigans created the MCU, thereby explaining why he breaks the fourth wall and how he knows so much about this shared world as he undoubtedly pokes fun at the beloved series of franchises.
