Spiderman II

Peter Parker struggles to balance his crime-fighting duties with the demands of his normal life. He loses a job, faces financial difficulties, and struggles to maintain his physics studies at Columbia University. Parker is estranged from both love interest Mary Jane Watson—now a successful Broadway actress—and best friend Harry Osborn, who accuses Spider-Man of murdering his father Norman Osborn, who was secretly the supervillain Green Goblin. Parker's Aunt May is threatened with foreclosure, and Daily Bugle editor J. Jonah Jameson continues to denounce Spider-Man as a menace to New York City.
Harry, now head of Oscorp's research division, sponsors the research of brilliant nuclear scientist Otto Octavius, Peter's idol. Octavius, who dreams of perfecting fusion power, wears a harness of powerful robotic arms with artificial intelligence for an experiment in sustained fusion. Though the experiment becomes unstable, the arrogant Octavius refuses to halt it, with disastrous results: his wife is killed, the neural inhibitor chip which prevents the arms from influencing Octavius's own mind is destroyed, and the arms are fused to his spine. Unconscious, he is taken to a hospital to have the appendages removed, but the tentacles develop their own ability to move at will and kill the surgeons, and Octavius escapes. The tentacles corrupt Octavius' mind, exploiting his vanity and ego, and he decides he must complete his experiment despite the danger. To finance his work, Octavius—whom Jameson nicknames "Doctor Octopus" or "Doc Ock"—robs a bank, where he takes Aunt May hostage after she and Peter were trying to refinance their house. As the villain and the hero battle, Peter finds his powers unreliable. He rescues May from Octavius, who escapes.
