Harold Osborn

"You took away mine, now I'm going to take away yours!"

- Harry Osborn

Harry Osborn is an old friend of Peter Parker and the son of Norman Osborn who becomes the supervillain Green Goblin.

The Amazing Spider-Man 2
Harry was a childhood friend of Peter Parker's who was sent off to a boarding school at a young age by his father, Norman. When he graduated, he moved to California and lived the life of a womanizing, spoiled rich boy.

Ten years later, Harry returned to New York to see his terminally ill father. Norman explained to him that his illness is hereditary, and that Harry was at an age where it first develops. He gave Harry a small device which he claimed contained his life's work. The next morning, Norman had died, and Harry became Oscorp's CEO.

Eventually, the first symptoms of Harry's illness began to show, but he used the device his father gave him to figure out that Spider-Man's blood could potentially save him. Harry asked Peter, who he knew was sending pictures of Spider-Man to the Daily Bugle, to get into contact with Spider-Man and give him a transfusion, but Peter refused, unsure of what effects the transfusion would have.

Peter visited Harry again, this time as Spider-Man, and refused Harry's offer again. The circumstances surrounding Harry only grow worse when the Oscorp board framed him for covering up Max Dillon's accident and remove him from his position as CEO. However, Harry's assistant Felicia Hardy informed him of technology within Oscorp which could help him.

Harry went to Ravencroft Institute and broke Electro out to help him get back into Oscorp. He found a suit of armor and other equipment made by Norman, as well as spider venom, which he used in an attempt to cure himself. Instead, they transformed him into a goblin-like monster.

After Peter and Gwen Stacy defeated Electro and decided to go to London together, Harry arrived with Norman's weaponry. He deduced Spider-Man's identity after seeing him with Gwen and, wanting revenge for being denied the blood transfusion, grabbed Gwen. He fought Spider-Man atop a clock tower near OscorPower. Spider-Man managed to get Gwen back and webbed her to a gear in the clock, but after he subdued Harry, the gear snapped the web and Gwen fell. Peter attempted to catch her with a web but she hit the floor, dying from the impact. Harry was sent to Ravencroft.

Later, Harry was visited by Gustav Fiers, who told him that he had found a man capable of operating a large suit of armor developed by Oscorp to fight Spider-Man. He also discussed with Harry his plans of creating a team to defeat Spider-Man.

Character traits

Powers and Abilities

 * Metamorphosis: Upon injecting himself with genetically modified spider venom, Harry transformed. The transformation changed Harry both physically and mentally. It turned his skin pale-greenish, made his hair stand up and gave him claws. It also made Harry insane. If the transformation was the result of the spider venom alone or of a combination between Harry's genetical disease and the venom is unknown. The transformation would have killed Harry, had he not put on the Oscorp Exo-Suit which healed him. The effects later wore off. Harry did, however, when asked if the effects had returned, say that, "It comes and goes".
