Editing Sinestro (section)

===Green Lantern===
Sinestro is born on the planet Korugar in space sector 1417. His dedication to preserving order originally manifests in his previous career, an anthropologist specializing in the reconstruction of ancient Korugan civilizations. One day, Green Lantern Prohl Gosgotha crash-lands near him, injured and apparently dying. Prohl gives his ring to Sinestro, who barely understands what to do with it before coming under attack from the Lantern's pursuer: a Weaponer of [[Qward]]. In the end, Sinestro has to destroy the ruins he was restoring to crush the Qwardian. Afterwards, Gosgotha turns out to still be alive and asks for his ring back so he can summon help. Addicted to the ring's immense power, Sinestro lets him die and convinces the Guardians that the ring chose him as Gosgotha's successor.<ref>''Secret Origins of Super-Villains 80-Page Giant'' #1, DC Comics, 1999</ref>

In ''Green Lantern (2005)'' #45, his wife is shown for the first time in a flashback and revealed to be the sister of [[Abin Sur]].

When [[Hal Jordan]] joins the [[Green Lantern Corps]], Sinestro, now a seasoned and respected Lantern, is assigned to be his instructor. Jordan is horrified at his new mentor's totalitarian methods, though Sinestro maintains that he is only doing what he considers necessary to protect Korugar. During his training, Jordan helps Sinestro repel an attempted invasion by the alien warlords known as the [[Khund]]s. When Jordan disobeys orders and contacts the Lanterns for help, Sinestro's dictatorship is exposed, and he is forced to appear before the [[Guardians of the Universe|Guardians]] for punishment. [[Katma Tui]], the leader of a Korugarian resistance movement who feels that Sinestro's "protection" keeps her people from growing as a society through contact with other alien races, is recruited as his replacement in the Corps. Katma Tui eventually grows into one of the most respected Green Lanterns, but she and the rest of Korugar initially resists her appointment to the Corps. Due to Sinestro's actions, Korugar has come to consider the symbol of the [[Green Lantern Corps]] an emblem of terror and oppression.
