He also appeared as the main antagonist of the Marvel Cinematic Universe film Spider-Man: No Way Home. He is the alter ego of Norman Osborn, the founder and CEO of Oscorp and the father of Harry Osborn, who befriended Peter Parker. After being exposed to the Goblin Serum, the Goblin persona is created inside Osborn's mind. A complete parallel to himself, it takes over Norman, driving him to kill and destroy anybody and everything until he becomes obsessed on destroying Spider-Man and everything he cares about, becoming his archenemy and the one foe who keeps haunting him even after death. Years later, he is resurrected by being accidentally transported to a different universe, where he teams up with other supervillains who shared the same fate. Not wanting to go back to a world where he's doomed to die, the Goblin decides to target this world's version of Spider-Man and his loved ones.
