The Green Goblin is a long-term recurring villain in the Spider-Man series, voiced by Neil Ross. However, though Osborn has been present almost from the beginning, the Goblin himself is a relative latecomer to the series, with Osborn not becoming him until Season 3, despite almost all other villains appearing in Season 1 (including the Hobgoblin). In the Goblin's debut episode, Enter the Green Goblin, Norman Osborn and his partner, Mendel Stromm, are coerced into creating a formula for the Kingpin that grants superhuman strength. Also, he is one of the few characters in the series who knows that Wilson Fisk is Kingpin. Unlike his comic counterpart, Norman Osborn here is not an insane version of himself, and has instead developed a multiple personality disorder. His other side is the Green Goblin, who acts on destroying everyone who has hurt Osborn throughout his life... Osborn is never truly responsible for his actions.
