The Sinestro Corps are a group of intergalactic terrorists meant to be the foil to the universe protecting Green Lantern Corps. Where the Green Lanterns protect and inspire will, the Sinestro Corps terrorize and spread fear.
After being excommunicated by the Guardians of the Universe from the Green Lantern Corps, Sinestro's obsession with revenge and universal order led him to create his own self-titled corps as a foil to the Guardians Corps. Forcing the Weaponers of Qward to mass-produce duplicates of his yellow ring and create a yellow Central Battery designed to gather the light of fear, Sinestro created his own Corps to destroy the Green Lanterns and bring order to the universe through fear.
The members of Sinestro's corps include mainly enemies of the Green Lanterns Corps, or extraterrestrial beings of great and renown fear throughout the universe. Their only mission is to kill those who are a part of the Green Lantern Corps and spread fear throughout the 3600 known sectors of the universe.
The Sinestro Corps play a large role in the Year Two comic series. Sinestro himself comes to Earth to enlist Superman into his war with the Guardians, and orders the execution of Green Lantern Kyle Rayner just outside the planet.
A massive legion of Sinestro Corps members arrive on Earth to help repel the squadron of Green Lanterns sent to bring Superman to Oa. Though the Sinestro Corps successfully captures the Green Lanterns, Superman forbids them from executing them and instead detains Kilowog's squad as prisoners of war, before ordering Sinestro to remove his Corps from Earth. Though Sinestro complies, he tells them to await his next orders.
Though not seen, it is revealed that several members of the Sinestro Corps are guarding the path from Earth to Oa, having attacked Guy Gardner along it, though Gardner managed to escape them.
The Sinestro Corps attacks Despero and throws him down to Earth, allowing Sinestro to kill him in the pretense of defending himself from Despero's attack on Earth. In the next chapter, a large gathering of Green Lanterns Corps members spot two Sinestro Corps members fleeing from the path to Earth from Oa, but they fail to escape and are attacked by the Corps, presumably killed.
The Sinestro Corps accompanies their leader and Superman to confront the Green Lantern Corps outside of Earth, but over a quarter of their numbers are wiped out by Mogo, with Sinestro himself saved by Superman.
The Sinestro Corps continue to wage war with the Green Lanterns, and while their numbers have been thinned out, they work with Superman in stretching the Green Lantern Corps too far from each other and even take the battles to Earth, forcing the Green Lanterns to protect endangered civilians.
War continues between the two Corps while the Sinestro Corps members that accompanied their leader to Ferris Aircraft are killed by Ganthet, and two more who attempted to save a fallen Superman after Ganthet attacked him are forced back by aircraft missiles.
The Sinestro Corps suffers heavy losses as they fall at the hands and power of Ganthet.
The Sinestro Corps are bolstered when Superman returns to their ranks, now wielding a Qwardian Power Ring and slaughtering Green Lanterns in droves. By the end of the Year Two series however, the Sinestro Corps have suffered massive casualties, with Sinestro and Hal Jordan being two of the few remaining alive, though Sinestro accomplished his goal of tearing the Green Lantern Corps apart at the cost of his own Corps.
