The big revelation in the mid-credits sequence to The Marvels concerns the arrival of the X-Men to the Marvel Cinematic Universe. This is easily the most important event in the saga's history and all the more pressing thanks to a very rough 2023. The scene finds Monica Rambeau awakening in a new reality and recuperating in the X-Mansion while Kelsey Grammer's Hank McCoy and a variant of her mother attend to her.
