Harry Osborn is Peter Parker's closest friend. Born to a wealthy family Harry's mother apparently died soon after his birth. He had flunked out of the many private schools his father had sent him to and wished to have his wealth and privilege downplayed to his new classmates. He constantly tries to impress his father Norman, a rich industrialist, who is very invested in his work having little time for his son. Harry eventually grows jealous of Peter's relationship with him as Norman admired Peter's intelligence and work ethic.

Harry starts a relationship with Mary Jane Watson whom he finds attractive. He is aware Peter does aswell and after he finds out attempts to justify himself saying that Peter never made a move, though she eventually falls for Peter. Harry eventually manages to somewhat mend the relationship he has with his father. After Norman's death as The Green Goblin, Harry believes that his father was murdered by Spider-Man, and seeks revenge, unaware that Spider-Man had in fact tried to save Norman's life, and went to great lengths to keep secret the billionaire's alter-ego as The Green Goblin.

The experiment failed and the company loses millions as a result. Harry was saved by Spider-Man in the disastor but still continues his vendetta. Ever the more bitter, Harry forms an alliance with Doctor Octopus to get his revenge, providing Octopus with a rare element ,tritium, that he needs to complete his fusion reactor in exchange for Octopus capturing Spider-Man.

Doctor Octopus brings Spider-Man back to Harry, who unmasks him in preparation to kill him. He is shocked to see that Peter is in fact Spider-Man. Afterwards, he begins to hallucinate, seeing his father'simage in a mirror who demands that Harry avenge his death. He refuses to do so and smashes the mirror only to find a hidden room concealed behind it. The room contained all of Norman's Green Goblin equipment and serum, which Peter had hidden when he brought his body back after his death. This discovery led Harry to realize that his father was the infamous Green Goblin.
