I am Doctor Octopus AKA Dr. Otto Gunther Octavius, also known as Doc Ock for short. I'm a scientist who sports four strong and durable appendages resembling an octopus's tentacles, which extend from the back of my body and can be used for various purposes. After my mechanical harness became permanently fused to my body during a lab accident, I turned to a life of crime, and came into conflict with the superhero Spider-Man.
