Predicting The Post-Credits Scenes Of Every Major 2018 Comic-Book Movie
2. Jean Grey Lives! - X-Men: Dark Phoenix
The Movie: Like X-Men: Apocalypse, X-Men: Dark Phoenix will centre around the younger generation of mutants, including Sophie Turner's Jean Grey, Tye Sheridan's Cyclops and Evan Peters' Quicksilver.
The movie will take heavy cues from the Dark Phoenix Saga, and fans of that comic-book storyline will know (spoilers!) that Jean sacrifices herself at the end of it. If the movie wants to be faithful to the source material then she'll need to perish here too, which provides the perfect setup for a post-credits stinger.
The Post-Credits Scene: Fans of the comics will also know that the Dark Phoenix Saga isn't the last we see of Jean Grey.
The character returns in a later story, and encounters a clone of herself created by the villain Mister Sinister. Weird. Jean also has no memory of the whole Dark Phoenix thing, and is able to continue her relationship with Cyclops without the burden of those memories.
While this is all pretty bonkers, the part about Jean Grey coming back to life is absolutely something future X-Men movies will explore. Sophie Turner's Jean has literally just been introduced - she wouldn't be killed off forever after just two movies.
With this in mind, it makes sense for Dark Phoenix's post-credits scene to contain a nod to Jean's impending resurrection. We could even see the character in full, but a quick glimpse of a shadowy figure or a falling strand of red hair would probably be a classier, less groan-inducing way to do it.
