The movie "Fantastic Four: First Steps" has two post-credit scenes.
- The first post-credit scene happens four years after the events of the movie, showing Sue Storm reading to her son Franklin. This scene features an ominous figure wearing a green cloak holding a metal mask, who is revealed to be Doctor Doom. This scene is important for the future of the MCU, especially leading into "Avengers: Doomsday."
- The second post-credit scene appears at the very end after all the credits have finished. It is a fun, lighthearted scene showing the in-universe Fantastic Four cartoon episode, which is more of a treat than plot-important.
So there are two post-credit scenes in total—one significant mid-credits scene and one final end-credits fun scene.
