Harold Osborn (USM)

Harold "Harry" Osborn is the son of Norman Osborn, the head of OSCORP. In high school, Harry became best friends with Peter Parker. Eventually, Norman became ill and died. Just before he did though, he revealed to Harry that the illness had been passed down to him. Harry then realized Peter took pictures of Spider-Man for the Daily Bugle and asked him to convince Spider-Man to meet with him. When doing so he asked Spider-Man for his blood sample, but he refused. Harry became outraged and eventually learned Peter was Spider-Man. He took a serum from OSCORP and became the Green Goblin while recruiting Electro and Rhino by his side. The three confronted Spider-Man but were defeated. Harry was assumed killed in battle until Electro confirms he was alive and working on the Sinister Project.
