Green Goblin is an alias for several fictional supervillains appearing in American comic books published by Marvel Comics. The first and best known incarnation is Norman Osborn, created by Stan Lee and Steve Ditko, considered Spider-Man's nemesis. Originally a manifestation of chemically induced dementia, others such as Norman's son Harry Osborn would take on the role. The Green Goblin is a Halloween-themed supervillain who has bat-like weapons, ghosts, and lanterns and in most incarnations uses a hoverboard or glider to fly.
