Otto Octavius had a turbulent upbringing. His father, a factory worker, was abusive and violent towards both Otto and his mother, leading Otto to be shy and reclusive in school. However, at his mother's insistence, he was determined not to become like his father and threw all his efforts into his education, regularly scoring top marks. It was hinted that he was a low-level telepathic mutant whose powers emerged at puberty; this mutation may have been responsible for giving his father an aneurysm as his father went to beat him. His father's death in an industrial accident pushed Otto further towards the study of, and obsession with, physical science.
Before his transformation into the megalomaniacal archenemy of the web-slinger, Otto was a brilliant and respected nuclear physicist, inventor, and lecturer. He became the youngest person to serve on the National Board of Nuclear Science. He designed a set of highly advanced mechanical arms to assist him with his research into atomic physics. The tentacled arms were resistant to radiation and were capable of great strength and highly precise movement. They were attached to a harness that fit around his body.
