Thaal Sinestro (/sɪˈnɛstroʊ/) is a fictional supervillain appearing in American comic books published by DC Comics, particularly those featuring Green Lantern. Sinestro is a former Green Lantern Corps member who was dishonorably discharged for abusing his power. He is the archenemy of Hal Jordan and founder of the Sinestro Corps.
