As is usually the case with MCU movies these days, The Fantastic Four: First Steps includes both a mid-credits and a post-credits scene. And also sticking to the traditional formula, one is a goofy little stinger, while another has serious ramifications for the MCU.

There have been strong rumours online suggesting that any post-credits scene could see former Iron Man star Robert Downey Jr appear as Doctor Doom for the first time, not an especially far-fetched idea given he's currently filming for his part in Avengers: Doomsday and the character is the Fantastic Four's most famous foe.

So yes, Doctor Doom does appear in First Steps. In the mid-credits scene, we jump four years into the future and see Sue Storm and her son Franklin reading together in their home in the Baxter Building.
