The Green Goblin, a supervillain in Marvel Comics and an archenemy of the superhero Spider-Man, has been adapted in various forms of media, including films, television series, and video games.

Neil Ross, Steve Blum, Alan Rachins, Steven Weber and Josh Keaton have provided the character's voices in various Spider-Man animated series.

The Norman and Harry Osborn incarnations of the Green Goblin appear in Spider-Man (1994), voiced again by Neil Ross and Gary Imhoff, respectively.

Norman eventually becomes the first Green Goblin following a gas accident at OsCorp that causes him to develop an alternate, more violent, and chaotic personality.

Harry becomes the second Green Goblin to exact revenge on the web-slinger, but is defeated by Spider-Man and the Punisher and sent to Ravencroft, where he receives medical treatment for his insanity.

An alternate universe variant of Norman Osborn / Green Goblin appears in the two-part series finale "Spider Wars".

Norman later assumes the Goblin alias after enhancing himself with the "Gobulin Green" formula and masquerading as a mysterious criminal equipped with stolen Oscorp technology who seeks to overthrow Tombstone as New York's reigning crime boss.

In the first season, the stress and constant disappointment in his life prompt him to steal "Gobulin Green", Oscorp's experimental formula that increases his self-esteem and aggressiveness.

The series' version of Norman is Harry's strict father and Oscorp's original CEO with high expectations and a willingness to steal others' technology to pass off as his own.

In the first season, he establishes the Osborn Academy for Geniuses after secretly causing Harry's suspension at Horizon High and to save his son from embarrassment while plotting against Spider-Man, Max Modell, and Professor Raymond Warren.

Norman returns in the third season as the Dark Goblin, having formulated a conspiracy that results in a symbiote invasion of Earth and turning the board of education against the web-slinger.

The Norman and Harry Osborn incarnations of the Green Goblin appear in Sam Raimi's Spider-Man trilogy, portrayed by Willem Dafoe and James Franco respectively.

While battling the Goblin persona and attempting to regain his bearings, a lost and overwhelmed Norman seeks refuge at May Parker's shelter and meets Peter-One before being imprisoned in the New York Sanctum alongside other alternate universe-displaced supervillains.

Peter-One attempts to cure them in the hopes of averting their original fates upon returning them to their respective universes, but the Goblin persona takes over Norman's body and convinces the other villains to fight back instead.

Afterwards, Peter-One and Three cure Osborn, ridding him of the Goblin persona, before Strange casts another spell to return all of the displaced individuals to their original universes.
