Harry Osborn was the son of Norman Osborn, and the best friend of Peter Parker. Harry later became New Goblin, the Green Goblin's Successor. Harry Osborn was Peter Parker's closest friend and the son of Norman Osborn, the CEO of Oscorp. Harry had a strained relationship with his father, who had high expectations for his son but was often too busy to be there for him. One day, when dropping Harry off at a class field trip, Norman was introduced to Harry's best friend Peter, who quickly made a good impression with Norman by understanding Norman's scientific work. Norman attended their graduation and congratulated Harry, and also took the time to console Peter for the loss of his uncle, and warmly accepted him as a brother figure to Harry and thus a part of their family. At the same time, Harry noticed that Mary Jane Watson, Peter's childhood crush, broke up with her boyfriend Flash Thompson.
While Aunt May was in hospital after being attacked by the Goblin, Harry went to visit her, but he found Peter and MJ getting intimate with each other. With his feelings hurt, Harry went to his father, telling him he was right about everything, MJ included, and unwillingly revealed to the Goblin Spider-Man's true weakness: Mary Jane. Later that very night, Harry found Spider-Man in his living room, depositing Norman's corpse on a sofa. Distraught and assuming it was Spider-Man who killed Norman, Harry tried to shoot the hero but missed.
(This Harry takes place After Spiderman 2 but before Spiderman 3 is why guess other than the Icon is showing his scarred face from Peter in the third installment.)
