The Green Goblin is the alias of several supervillains appearing in American comic books published by Marvel Comics. The first and best-known incarnation, Norman Osborn, created by Stan Lee and Steve Ditko, is generally regarded as the archenemy of Spider-Man.[1] Originally a manifestation of chemically induced insanity, others such as Norman's son Harry Osborn would take on the persona. The Green Goblin is a Halloween-themed super villain whose weapons resemble bats, ghosts and jack-o'-lanterns and in most incarnations uses a hoverboard or glider to fly.

Comics journalist and historian Mike Conroy writes of the character: "Of all the costumed villains who've plagued Spider-Man over the years, the most flat-out unhinged and terrifying of them all is the Green Goblin."[2] The Green Goblin has appeared in numerous media adaptations of Spider-Man over the years, including films, animated television series, and video games. Norman and Harry Osborn were portrayed by Willem Dafoe and James Franco in Sam Raimi's Spider-Man film trilogy (2002–2007), and by Chris Cooper and Dane DeHaan in the film The Amazing Spider-Man 2 (2014). Dafoe reprised his role as Norman Osborn in the Marvel Cinematic Universe film Spider-Man: No Way Home (2021).
