15 X-Men References & Easter Eggs In The MCU So Far

Warning! Contains spoilers for The Marvels While the X-Men are on their way to the MCU at some point in the future, Marvel Studios has still managed to sneak in a number of references to mutants into the ever-growing shared universe. Since 2008’s Iron Man kicked off the MCU movie timeline, has introduced hundreds of characters from the Marvel universe to help flesh out their interconnected multiverse. However, back when Marvel Studios was still fresh, they didn’t have access to significant characters like Spider-Man, the Fantastic Four, and the X-Men. Before Disney acquired 21st Century Fox, the word “mutant” could never even be said in a Marvel movie or TV show (let alone referencing the X-Men), and characters that both studios shared had access to had to be retooled for the respective universes.
