In Ultimate Spider-Man , Doctor Octopus was a lab assistant to Norman Osborn. He was caught in a lab accident, grafting morphing metal arms onto him. He became a killer until stopped by Spider-Man. Afterwards, Doc Ock was cured of his amnesia and remembered the secret identity of Spider-Man. He made an appearance in the Ultimate Six miniseries and then finally in the Hollywood arc before Nick Fury took his original arms and melted them down. However, there have since been hints that Doc Ock might return.
