Sinestro was a former member of the Green Lantern Corps and later he became their greatest enemy.
Deemed unfit to wield the power of the Green Lantern's ring by the Guardians of the Universe, Sinestro was brought down by his fellow Green Lanterns, including John Stewart, and stripped of his power ring. Swearing a blood oath of revenge and vowing to destroy the Green Lantern Corps, Sinestro began hunting Green Lanterns and collecting their rings. After dispatching Abin Sur, Sinestro was defeated by Abin Sur's successor Kyle Rayner and Superman.
Later recruited into Grodd's Secret Society in a ploy to avenge himself on John Stewart, Sinestro was defeated once more. Sinestro attempted his most ambitious revenge scheme next, when he impersonated Stewart to discredit him as a criminal. A weakened Stewart was nearly imprisoned as a result and was only able to defeat Sinestro and clear his name with Static's assistance. Sinestro later joined the Legion of Doom, notably taking part in a train robbery with Doctor Polaris, Tala, and Lex Luthor.
When the Society split between loyalty to Grodd, their original leader, and Luthor, his usurper, Sinestro sided with Luthor. Surviving the battle between both sides, Sinestro saved the lives of his allies by shielding them when a newly resurrected Darkseid destroyed the Society's ship. Putting aside his feud with Green Lantern and the Justice League, Sinestro helped fight back Darkseid's forces, taking on Parademons in Tokyo. In the aftermath, Sinestro and the other surviving members of the Society were given a five minute head-start to run for their defense of the Earth.
Powers & Abilities
Sinestro has the same powers and abilities as members of the Green Lantern Corps thanks to his yellow Power Ring.
In the DC comics, Sinestro was once the Green Lantern of Sector 1417, often regarded as the greatest Lantern in the history of the Corps. When the Guardians assigned him to train Hal Jordan, he discovered that Sinestro used his power ring to bring peace to Korugar by installing himself as a dictator. The Guardians stripped him of his ring and banished him to Qward, but the Weaponers of Qward gave him a Yellow Power Ring and allowed him to return to his universe, where he became the archenemy of the Corps and Hal Jordan, who many now believed to be the greatest Lantern in the History of the Corps.
Recently, Sinestro allied with the Manhunters, the Anti-Monitor, the Weaponers of Qward, and Parallax to form his own "Sinestro Corps", giving living beings Qwardian yellow power rings fueled by Parallax, with the stated purpose of forcing the Guardians to allow the Green Lantern Corps to use deadly force against opponents to sully their reputation. He recruited Hank Henshaw, Amon Sur (son of Abin Sur), and a number of others before the Sinestro Corps were defeated by Hal Jordan and Kyle Rainer in the Battle of Coast City. Currently, Sinestro is a prisoner on Oa, awaiting execution.
In the Duck Dodgers episode The Green Loontern, Sinestro was voiced by John DeLancie. Dodgers pointed out that Sinestro looks like the Devil, to which Sinestro replied that that he's heard that before.
