Harold Osborn (DOSM)

Harold "Harry" Osborn is the son of Norman Osborn, the head of OSCORP. In high school, Harry became best friends with Peter Parker. There began to be a fracture in the two's relationship. Especially one afternoon when Peter didn't show up go home from school with Harry because he was off as Spider-Man. Harry became impatient and walked home himself. When he tried to enter his home, he realized the doors were locked. Norman's long time mentor, Ben came to welcome Harry, and informed him that his father had died. Eventually, Harry was diagnosed with Norman's same illness. Realizing Peter was in close contact with Spider-Man, he asked Peter to set up an appointment for him and Spider-Man to meet. When they finally met, Harry asked Spider-Man for his blood sample in hopes to cure himself. Spider-Man refused. Harry became infuriated, believing all hope was lost until Ben offered him another option. Ben gave Harry a serum from OSCORP that not only cured him, but turned him into the Green Goblin. Harry confronted Peter after learning he was Spider-Man, and attempted to kill him. He failed however, and Peter assumed Harry to be dead forever. However, Harry lived and returned to Ben. The two broke Cletus Kassidy out of prison and made him into Carnage. Harry became tired of everyone judging him for his illness so he decided to give Spider-Man the symbiote in an attempt to turn him into a freak so he'd know what it felt like. However, the symbiote became more powerful and Spider-Man escaped. Later however, after Spider-Man had rid himself of the symbiote, was confronted by Carnage and Green Goblin. Carnage died in the battle. With Gwen Stacy caught in the battle! Peter had no choice but to kill Harry.
