Sinestro of the Planet Korugar was one of the greatest Green Lanterns of all time but when his wife and children were slaughtered by the ruler of Korugar, because of that Sinestro thought himself that the only way of making the universe a better place is by fear and force so he kills the ruler of his home planet and he along with the other Lantern rogue called Boodikka decided to rule the Korugar as a dictator and then gain control in the other existent planets in the universe, then the Green Lantern Corps tried to stop Sinestro of abusing of his power but he and Boodikka kill them one by one taking their rings and absorbing the Central Power Battery in Oa which then Sinestro was possesed by Parallax (who was trapped inside of the battery) only to confronted by the Guardians who used all of the power of Ion to stop Sinestro and Boodika and imprison them for their crimes, but Sinestro and Boodikka escape and swore that they will found their own Lantern Corps by using the Qwardian Element from the planet Qward and then show the Guardians that a new universal order is about to begin, so Hal Jordan, the Green Lantern Corps and even the Justice League must stop the Sinestro Corps before they take over the universe.
