Wondering how Avengers: Doomsday connects to The Fantastic Four: First Steps? A key mid-credits scene introduces a mysterious presence, hints at a growing multiversal threat, and sets up one character’s deeper interest in Franklin Richards. With Franklin’s abilities exposed and his importance established, the MCU moves one step closer to its next multiversal showdown.
Here’s how The Fantastic Four ties into Avengers: Doomsday and what it means for what’s coming next.

How does Doctor Doom connect The Fantastic Four: First Steps with Avengers: Doomsday?
Doctor Doom connects The Fantastic Four: First Steps with Avengers: Doomsday through a mid-credits scene set four years after the events of the film.
Sue Storm reads to her son Franklin Richards, who is portrayed as intellectually advanced. After stepping away to find another book, Sue senses a presence and activates her powers. Upon returning, she finds Franklin calmly sitting with a cloaked figure in a green hood who holds a removed metal mask—recognizable as Doctor Doom’s. The scene cuts to black with the words: “The Fantastic Four will return in AVENGERS: DOOMSDAY.”
Director Matt Shakman confirmed that the Russo brothers filmed the scene, which explains why Doom does not appear in the main narrative. Although Robert Downey Jr. plays Doom in Avengers: Doomsday, this appearance does not show his face. The scene highlights Doom’s interest in Franklin’s powers, which Galactus previously tried to claim.
The film implies that Victor Von Doom comes from Earth-828, the same timeline as this version of the Fantastic Four. During the Future Foundation hearings at the United Nations, Sue Storm leads the proceedings while Latveria’s nameplate sits empty, with no representative present.
This scene indirectly confirms Doom’s existence. In the comics, Doom originates from Latveria and eventually rules the nation; the inclusion of Latveria in Earth-828 reinforces this connection. He is best known as the primary antagonist of the Fantastic Four.
While Doom’s face remains hidden, the post-credits scene reveals his comic-accurate mask and marks his formal introduction into the MCU. Franklin’s cosmic powers, implied to rival Galactus’ hunger, appear to be the reason for Doom’s arrival. His interest in the child aligns with the multiversal threats set to unfold in Avengers: Doomsday.
