Bart Hamilton is a doctor who is tasked with treating a mentally disturbed
Harry Osborn, who had been captured after some time acting as the Green Goblin. Under hypnosis, Osborn tells Hamilton everything about the Goblin, as well as
Spider-Man's secret identity. Hamilton is skeptical about these stories, but finds them to be true. After curing Osborn of his insanity, and temporarily making him forget his time as the Green Goblin, Hamilton investigates the old headquarters of the Green Goblin. After being exposed to the same chemical formula that
Norman Osborn and Harry Osborn used in the past, Hamilton becomes the third Green Goblin. After a brief stint trying to rule the criminal underworld, Hamilton accidentally kills himself in an explosion during a fight with Harry Osborn and Spider-Man. ==References==
