Doctor Doom, real name Victor von Doom, is a Marvel Comics supervillain. Created by Stan Lee and Jack Kirby, he debuted in The Fantastic Four #5 (July 1962). His full origin was told in Fantastic Four Annual #2 (1964).

A brilliant scientist, Doom was once a classmate of the Fantastic Four's Reed Richards. However, he became embittered by his jealousy of Richards and by facial scars received from an experiment gone awry, and perhaps from impatiently donning a steaming-hot iron mask forged by mystic monks.

Doom is considered the archenemy of the Fantastic Four, but has also been added to the rogue galleries of the Avengers, the Punisher, the Silver Surfer, the Hulk, Iron Man and Spider-Man. He is one of the comic book industry's most recognizable and archetypal supervillains. His ruling of the small nation of Latveria provides him with diplomatic immunity, an ingenious element never previously used in comic books.

He is not to be confused with the obscure Fox Comics villain Dr. Doom, introduced in Science Comics #1 (Feb. 1940), and who, like Marvel's Dr. Doom in Astonishing Tales, was the star of his own features in Science, Big 3, and The Green Mask. Neither are to be confused with the supernatural monster-hunter Doctor Droom a.k.a. Doctor Druid, Marvel's first ongoing Silver Age hero.
