Victor von Doom (also known as Doctor Doom) is a fictional character who appears in Marvel Comics publications. Created by Stan Lee and Jack Kirby, the character first appeared in Fantastic Four #5 (July 1962) wearing his trademark metal mask and green cloak. The son of a gypsy witch, Doom is a recurring supervillain, arch enemy of the Fantastic Four, and leader of the fictional nation of Latveria. He is both a genius inventor and a sorcerer, and has served as a primary antagonist and occasional protagonist in the Marvel continuity since his creation. While Doom's chief opponents have been the Fantastic Four, he has also frequently battled Spider-Man, Doctor Strange, the Avengers, the X-Men, the Punisher, Blade, Iron Man, and the Silver Surfer, among others.
Doctor Doom has been featured in other Marvel-endorsed media such as feature films; video games; television series and merchandise such as action figures and trading cards. Doom was ranked as the 4th Greatest Villain by Wizard on its 100 Greatest Villains of All Time list. IGN's list of the Top 100 Comic Book Villains of All Time ranked Doom as #3.
