Norman Osborn, also known as the Green Goblin, is the main antagonist of Sam Raimi's Spider-Man film trilogy, appearing as the main antagonist of Spider-Man and the posthumous overarching antagonist of Spider-Man 2 and Spider-Man 3. He also appears as the main antagonist of the Marvel Cinematic Universe film Spider-Man: No Way Home.
He is the founder and CEO of Oscorp as well as the father of his son Harry who befriended the latter's best friend Peter Parker. After being exposed to the Goblin Serum, he develops a split personality that drives him to become a supervillain bent on securing his company and more power, becoming focused on destroying Spider-Man and everything he cares about. He soon becomes Spider-Man's archenemy, being the one foe who keeps haunting him even after death.
Years later, the Green Goblin is accidentally transported to a different universe, where he teams up with other supervillains, from his home universe and from an alternate one, who shared the same fate. Not wanting to go back to a world where he is doomed to die, the Green Goblin decides to target this world's version of Spider-Man and his loved ones. He is one of that Spider-Man’s greatest enemies, alongside Mysterio.
