Thaal Sinestro was a former Green Lantern who turned on the Green Lantern Corps and becoming an intergalactic criminal.
Thaal Sinestro was a distinguished member of the Green Lantern Corps. Despite his service to the Corps, Sinestro was discovered trying to sell the secrets of the Corps' power rings to enemies of the Galactic Confederacy. He was dishonourably discharged and stripped of his power ring. However, Sinestro later created his own corps, loyal to the highest bidder, with yellow power rings of his own design. Considered a most dangerous enemy to the Green Lantern Corps; since his discharged and betrayal, Green Lanterns have been ordered to arrest him at all costs - dead or alive.
