Hector Hammond is a supervillain appearing in American comic books published by DC Comics who is primarily an enemy of Green Lantern. Peter Sarsgaard played the role of Hammond in the 2011 film Green Lantern. Publication history Hector Hammond originally appeared in Green Lantern (vol. 2) #5 (March–April 1961) and was created by John Broome and Gil Kane. Fictional character biography The character Hammond is a petty criminal on the run from the law when he discovers the fragments of a strange meteor in the woods (later retconned as part of the same meteor that lands in Africa, super-evolving Gorilla Grodd and the other gorillas of Gorilla City). Observing that radiation from the meteor caused the nearby plants to evolve rapidly, Hammond kidnaps four scientists and exposes them to the meteor on a remote island. The radiation causes their intellects to evolve, but also has the side effect of sapping their wills. Hammond forces the scientists to use their heightened intellect to create amazing new inventions, which Hammond sells for his own profit. Hammond rapidly becomes a rich celebrity due to the wealth he has acquired. Green Lantern Hal Jordan asks his friend and mechanic, Thomas Kalmaku, to take on the role of the Green Lantern while Jordan investigates Hammond. Jordan creates a duplicate power ring and costume for Kalmaku to fool Hammond and tells him to fly above Coast City so it would be thought Green Lantern was there. The scientists tried to use a device to bring this Green Lantern to them, but the ring was first pulled off his finger and fell on the island where Hammond found it. Unaware of the impersonation, Hammond steals his ring and turns Kalmaku into a chimpanzee. Jordan confronts Hammond personally in a battle of power rings that ends only when the charge of Hammond's ring runs out, allowing Jordan to capture him and restore Kalmaku and the scientists. He removes the scientists' memory of their knowledge and gets rid of the inventions as well. Hammond returns in Justice League of America #14 (September 1962). He manages to escape from prison and deliberately exposes himself to the meteorite. The radiation causes his brain to grow to enormous size, granting him psionic powers as well as immortality. He captures Green Lantern using a "de-memorizer" invented by Amos Fortune, but he is later captured. His body later becomes immobilized, and he loses the
