History: Once he was Otto Octavius, a brilliant and respected scientist who had designed a set of robotic arms to aid his research into atomic physics. But a freak laboratory accident exposed Octavius to intense radioactivity, grafting his mechanical appendages to his body and granting him complete telepathic control over them. Worst of all, the accident altered Octavius' mind, transforming him from a timid physicist into a criminally insane megalomaniac.

Armed, quite literally, with four powerful and nearly indestructible tentacles, Octavius took the name Doctor Octopus. He has sought to amass wealth and power through various criminal activities, and has formed gangs, such as the original Sinister Six, in an attempt to dominate crime in New York City. Through the years, Doctor Octopus has shown himself to be one of Spider-Man's most formidable foes, and their battles have proven to be as brutal as any the web-slinger has ever fought.

Known Superhuman Powers: Doctor Octopus' abilities derive from his four titanium tentacles. Attached to a stainless-steel harness encircling his lower chest and waist, each telepathically-controlled, telescoping tentacle is capable of moving at speeds of 90 feet per second and can strike with the force of a jackhammer. Also, Doctor Octopus can generate a 50-mph wind by spinning the prehensile limbs like a giant fan. At full extension, the mechanical appendages allow him to travel high above the ground as if on stilts, either using two tentacles, or all four for maximum speed (about 50 mph). Each tentacle is about 5 inches in diameter and terminates in three, single-jointed pincers. The pincers can rotate in relation to the tentacle for 360 degrees, in a screwdriver-like twisting motion.
