The movie "Fantastic Four: First Steps" has two end credits scenes.

1. The first is a mid-credits scene that takes place four years after the film’s events. It features the Fantastic Four family in the Baxter Building with Sue Storm reading to her son Franklin. A mysterious figure in a green cloak holding Doctor Doom's iconic mask appears, setting up the villain's return and hinting at the next MCU film, "Avengers: Doomsday."
2. The second is a post-credits scene with a lighter and nostalgic tone, showing a retro-style animated homage to the 1960s Fantastic Four cartoons, featuring the team in classic costumes battling villains.

So, there are two end credits scenes in total—one important for the MCU storyline and a second fun, nostalgic one.
