While post-credits scenes have become heavily associated with the Marvel Cinematic Universe, it was the X-Men Film Series (made by 20th Century Fox rather than Marvel Studios) that first made the stinger into a staple of superhero movies and especially those based on Marvel products:
- X-Men: The Last Stand: Professor X transfers his mind into the man with the coma...
- X-Men Origins: Wolverine had, depending on your screening, either a now-amnesiac Logan in a bar, "drinking to remember" or the living disembodied head of Deadpool, having gained his mouth back and his Medium Awareness as well. There was also General Stryker getting arrested, but everyone got that one.
- The Wolverine: Two years later, Magneto is shown to have regained his mutant power and Xavier is revealed to be alive. They both meet with Logan at an airport and ask him to join them fighting the new weapon that the humans have created to destroy the mutants.
- X-Men: Days of Future Past: En Sabah Nur uses his Mind over Matter powers to build a pyramid in Ancient Egypt while his Four Horsemen are seen in the background.
- Deadpool: The after-credits scene is where Deadpool tells the people in the audience to go home, since the show's over (while dressed as Ferris Bueller to make sure the Shout-Out is clear). However, he later relents, and uses the time left in the movie to mention that the sequel will bring Cable into the mix.
- X-Men: Apocalypse: It involves the abandoned Alkali Lake facility being raided by Essex Corp. If you don't understand the significance, the X-Men villain Mr. Sinister's name is Nathaniel Essex. The genetic info about Wolverine may be used to create X-23.
- Logan: Inverted. The No Good Deed teaser for Deadpool 2 is shown before even the studio logo appears, almost as if it were one of the theatrical trailer previews. It doesn't appear outside the U.S. and Canada, though.
- Deadpool 2: A mid-credits scene where Negasonic Teenage Warhead and Yukio manage to repair Cable's time travel device and give it to Deadpool. He uses it to undo Peter and Vanessa's deaths. Then he travels to the final battle of X-Men Origins: Wolverine and kills that version of Deadpool. Then he murders Ryan Reynolds before he can accept his role in Green Lantern (2011).
- Averted with Dark Phoenix and The New Mutants, as both films were released after the Disney buyout.
