Hector Hammond

One of Hal Jordan's frequent enemies, Hector Hammond first appeared in Green Lantern (vol. 2 #5, 1961) was given massive psionic abilities when he was exposed to the same meteor that gave Gorilla Grodd his abilities. But that came later on, first he exposed four scientists to the meteor, causing their intellects to increase rapidly while sapping their free will. Hammond forced the scientists to build amazing inventions that he sold as his own, building enormous wealth for himself, until he was stopped by Hal Jordan. Upon escaping from prison, he deliberately exposed himself to the meteor. This is when he gained his psionic powers and immortality as well, but at the cost of immobilization and loss of speech, being able to communicate only telepathically. He was responsible for the creation of the second Royal Flush Gang in Justice League of America #203 (1982). When he appears in the series Blackest Night crossover, he escapes from prison, swallowing the orange lantern of Larfleeze and becomes the new host for Ophidian, the embodiment of greed, who attempts to make Larfleeze his slave after being forced to live in the lantern for years. After Hector's desires start to override his own, he leaves Hector's body in search of Carol Ferris. Hector will appear in the upcoming Green Lantern movie, portrayed by Peter Sarsgaard gaining his powers after absorbing a small piece of Parallax that was housed in Abin Sur's body.
