Dr. Octopus

First Appeance: Amazing Spider-man vol 1, #3
The Story: Otto created a harness with mechanical arms, using it to safely manipulate toxic materials from a distance. When he became physically and mentally fused to these arms after a freak industrial accident, the formerly mild-mannered Octavius became the infamous criminal mastermind known as Doctor Octopus. His sanity after the accident has been strongly questioned, much to his personal annoyance. Abilities: An authority on nuclear radiation and atomic theory, Doctor Octopus controls his four extra arms mentally. With them, he is capable of performing several tasks simultaneously. He can also use them to scale walls, to stalk over cars, and to knock your average Arachnid super-hero senseless.
