A career criminal, Hector Hammond was evading the law in the California hills when he discovered a fallen meteor that was causing nearby foliage to evolve into a form that would not exist for anther 100,000 years. Transporting the meteor back to his hideout, Hammond kidnapped four prominent scientists and exposed them to the meteor's rays, which evolved them into humans with advanced mental abilities, but weakened willpowers. Hammond forced the scientists to invent advanced weapons in which to commit crime. The kidnapping of the four scientists was being investigated by Green Lantern, who defeated Hammond, turning him over to authorities, and restored the scientists to normal.
Escaping prison months later, Hammond subjected himself to the meteor's radiation evolving himself into a futuristic human with and over-sized brain. Determined to achieved immortality, Hammond filtered the meteor's radiation and exposed himself a second time, but instead of achieving immortality he became physically immobile.
With no means of movement, but possessing an ability to attack others with his mind, Hammond attacked the one who originally incarcerated him in an attempt to steal the Green Lantern Ring to grant himself a means of mobility. Although he initially failed, Hammond has remained a dangerous foe even incarcerated within his own body.
