Fictional character biography
Dr. Bart Hamilton first came into contact with the legacy of the Green Goblin when he treated a mentally disturbed Harry Osborn, who had just been captured after a long stint as the Green Goblin. Under hypnosis, Osborn told Dr. Hamilton everything about the Goblin; he even told Hamilton Spider-Man's secret identity. Hamilton was sceptical about these stories, and checked on them, finding them to be true. After curing Osborn of his insanity, and (temporarily) making him forget about ever being the Green Goblin, Hamilton investigated the old headquarters of the Green Goblin and, after being exposed to the same chemical formula that Norman and Harry used in the past, became the third Green Goblin.
