Doctor Octopus

A former nuclear physicist and atomic researcher, Otto Octavius' life changed forever when one of his experiments went horribly wrong involving his four mechanical appendages used to assist him in his experiments. From then on, Octavius soon after his initial encounter has become one of the most dangerous enemies of Spider-Man and friends.

Doctor Octopus has a genius-level intellect related to the field of atomic physics and radiation. He holds a PhD in nuclear science, and is skilled as an inventor and an engineer. He is an excellent tactician, as well as being a charismatic leader. He is able to effectively segment his attention in such a way as to engage multiple people in battle while simultaneously performing some other, more delicate task.

He has telepathic control over four prehensile, electronic octopus arms that are attached to his torso. Even when the harness is detached from his torso, he maintains a level of telepathic control over the arms, even over great distances. The arms, which have pincers at the end, can extend to 24 feet at the maximum, and are capable of superhuman strength and enhanced reaction time. He can use them to lift a maximum of three tonnes per arm, though at least one arm must support his body, and he can use them similarly to legs, to lift his body and move rapidly over a variety of terrains, and also to scale walls. He wears an armored body suit because, while capable of dishing out an enhanced beating, his body is that of a regular human, and has become increasingly worn down by the constant fighting and injuries he has sustained. This suit adds an additional four cybernetic arms. His telepathic control also extends over an army of octobots, small, eight-limbed robots.
