The mid-credits scene of The Fantastic Four: First Steps provides a chilling glimpse into the team's future, four years after their initial conflict with Galactus. Sue Storm is shown with her son, Franklin Richards, when a mysterious cloaked figure appears. This dramatic reveal, identifiable by his green attire and a distinctive mask, confirms the long-awaited introduction of Doctor Doom into the Marvel Cinematic Universe. 

This dramatic moment not only introduces a formidable new villain but also establishes a critical link to upcoming major events in the Marvel Cinematic Universe. Doctor Doom's unexpected appearance directly ties into the upcoming Avengers: Doomsday film, where Robert Downey Junior is about to portray the iconic villain. While Doom's precise intentions regarding young Franklin remain unstated, the child's extraordinary powers would undoubtedly appeal to a supervillain of his caliber.

The encounter depicted in the post-credit scene strongly suggests a catalyst for the Fantastic Four's eventual journey into Earth-616, the main universe where other Marvel heroes reside, setting the stage for monumental conflicts.Moreover, this is not the only post-credit scene raising anticipation; rather, there are a few other scenes and theories confirming the doctor's arrival.

Multiverse crossroads: The Fantastic Four's interdimensional journey

The Fantastic Four: First Steps establishes its narrative on Earth-828, a retro-futuristic world existing in a distinct corner of the vast Marvel multiverse. However, a separate post-credits scene from Thunderbolts* reveals that the Fantastic Four's spacecraft, Excelsior, is appearing within Earth-616, the primary universe of the Marvel Cinematic Universe. This confirms their imminent arrival on the familiar heroic landscape.

 One reasonable theory suggests Doctor Doom's actions, perhaps the kidnapping of young Franklin, could force the family to cross the multiverse in chase. This interdimensional shift aligns perfectly with Samuel Sterns' warning in Captain America: Brave New World, emphasizing that the multiverse is indeed on its way. In addition to the crucial mid-credits scene in the 60s Sci-Fi, The Fantastic Four: First Steps features a second post-credits sequence after the full credits roll. This final cut serves as a fun bonus and a nostalgic tribute to the Fantastic Four's animated past.
