Doctor Doom’s first comic appearance is identified as Fantastic Four #5 (1962). Robert Downey Jr.’s Doctor Doom has a separate screen timeline: Doom appears in the mid-credits scene of 2025’s The Fantastic Four: First Steps, and Disney lists Downey as Victor von Doom / Doctor Doom in Avengers: Doomsday.
Doctor Doom’s first appearance in the Fantastic Four comics
Doctor Doom’s comic debut is Fantastic Four #5, published in 1962. That issue marks the character’s first appearance; it is not an appearance by Robert Downey Jr., who joined the Marvel Cinematic Universe decades later. Marvel’s Kirby 100 feature discusses Doom in connection with the issue, while a specialist comic-reference entry identifies the issue and year explicitly.
Readers looking for the comic can search for “Fantastic Four #5 Doctor Doom first appearance.” Reprints and collected editions may differ in contents, so check the specific edition rather than assuming every collection reproduces the complete issue.
Robert Downey Jr.’s Doctor Doom appearances and announcement
The Fantastic Four: First Steps
Doom appears in the mid-credits scene of The Fantastic Four: First Steps, according to TheWrap’s explanation of the film’s credits scene. This establishes a Doom appearance in the released film; it does not establish that Downey’s face is shown or that the scene contains a full performance by him. Marvel’s official film page confirms the film’s identity, but does not provide the credits-scene detail.

Avengers: Doomsday
Downey was announced as playing Doctor Doom at Marvel Studios’ San Diego Comic-Con presentation in July 2024. D23’s July 28, 2024 report described the announcement as a new MCU role. Director and producer Joe Russo said at the announcement, “If we’re gonna bring Victor Von Doom to movie theaters worldwide, then I think we’re going to need the greatest actor in the world to play that character.”
Disney’s current official Avengers: Doomsday page identifies Downey as Victor von Doom / Doctor Doom and lists the film’s release date as December 18, 2026. An earlier D23 announcement, published March 26, 2025, said production had begun and gave May 1, 2026 as the planned release date; that historical date has been superseded by Disney’s current listing.
