The Hobgoblin is the alias of several supervillains appearing in American comic books published by Marvel Comics, most of whom are depicted as enemies of the superhero Spider-Man and belong to the collective of adversaries that make up his rogues gallery, most of whom are brainwashed by the Winkler Device into becoming Hobgoblins. Created by writer Roger Stern and artist John Romita Jr., the first incarnation of the Hobgoblin was introduced in The Amazing Spider-Man #238 as a criminal mastermind equipped with Halloween-themed weapons similar to those used by the Green Goblin.
