Created by John Broome and Gil Kane, Sinestro is a former Green Lantern Corps member who was dishonorably discharged for abusing his power.Ted Levine, Miguel Ferrer, Xander Berkeley, Ron Perlman, Victor Garber, Jason Isaacs, and others have voiced the character in animated television series and films.When Jordan disobeys orders and contacts the Lanterns for help, Sinestro's dictatorship is exposed, and he is forced to appear before the 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.Creating a yellow power ring for Sinestro to use, the Weaponers send him back to the "positive matter" universe to seek revenge.Before the Guardians take a leave of absence from their universe to attempt mating with their female counterparts, the Zamarons, they construct an inescapable prison for Sinestro and thousands of others on Oa.Wielding nearly unlimited power, Sinestro murders entire star systems until he is finally subdued by the Green Lantern Corps of Earth.Yet Sinestro earns an even greater personal victory as the so-called "yellow impurity" turns out to be a sentient entity known as Parallax, the living embodiment of fear.The newly restored Corps is short-lived, thanks to the inadvertent efforts of the alien warlord Mongul and Hank Henshaw, a cyborg who is at the time impersonating Superman.Parallax then bonds to Jordan, who takes the entity's name for himself, and promptly finishes off the Green Lantern Corps by absorbing the Central Battery's energies into himself.created the duplicate Sinestro after watching videos of his old battles, believing that he is just playing a computer game, and unaware of the real-world damage that he is causing.Although he lacks Sinestro's tactical genius, the unrestrained use of his power destroys a bridge and a building, nearly suffocating Wonder Woman before he is defeated by the hero Champion (really a disguised Hercules).Although he initially distracts Hal at a crucial moment, Kyle's ring's immunity to yellow proves vital in preventing Sinestro from executing the Guardians of the Universe.Nearly killing the two heroes, Sinestro is stopped by the newly resurrected Hal Jordan, who reclaims his ring and is purged of Parallax's influence.When Sinestro formed his insignia from blood, the power rings stationed on Oa seemed to react violently, threatening to break free of their confines.[18] After being taken to Ysmault, he is nailed to a cross to await his execution at the hands of Atrocitus, who wishes to make Sinestro suffer by taking revenge on everything he cares for.The Sinestro Corps' celebration is cut short when a ship crash lands nearby, containing Black Lanterns Abin and Arin Sur.Under Indigo-1's direction, they combine their lights, thinking it will destroy the Black Lanterns' source of power, but this fails and in an attempt to bolster their ranks, Ganthet duplicates the Corps leaders' rings, having them seek out candidates to deputize.This enables Hal to access the Entity's power and transform himself and the other heroes into White Lanterns, resurrecting Black Hand and breaking Nekron's tether to the living universe.[35] In the War of the Green Lanterns storyline, Lyssa Drak traps Sinestro and the other 'New Guardians' in the Book of the Black while trying to recover the emotional entities from Krona.Hal and others escaped only thanks to their prior experience with Parallax granting them an immunity to the initial assault, to give himself a weapon against the other Lanterns.[51] When Simon Baz enters the Dead Zone during a fight with Black Hand, a way out is provided by Green Lantern B'dg.He then claims the yellow power battery instead and leaves to exact revenge, as he became a member of the Sinestro Corps again while Simon Baz fails to resurrect Korugar as well after he was rejected as an unsuitable host while wielding the white ring.[58] When it comes to the final battle against the Crime Syndicate, Sinestro and Black Adam move the moon where the sun ends up weakening Ultraman.He forces Arkillo to yield and kills a Yellow Lantern who tries to attack him from behind as he said that Sinestro must die, melting his ring to stop it from finding a replacement.Sinestro brings a Green Lantern Power Battery for Soranik to recharge and she joins his team in rescuing a group of Korugarians that are being sold into slavery on the planet Muz.[65] Subsequently, in DC Rebirth, Warworld transports to the ruins of the planet Oa, while Sinestro (with seemingly old age) plans to control the universe.[68] Later, Sinestro alliances with the priests of the Sacrament, who are an enemy of the Green Lantern Corps, who reconsider him to aiding enforcement controls of the Vega system.Hal then uses his energies as a living construct to incinerate the Fear Warlord and destroys Warworld, apparently sacrificing himself and killing Sinestro in the process.Physically, the Master of Fear gains a dynamism boost as well, putting him on par with some of DC's strongest characters such as Superman or most notably Black Adam, shown when both he and Adam moved Earth's moon out of the path of its sun together,[59] or when he was under assault by equally powerful assailants such as Superwoman, Deathstorm and Alexander Luthor who had stolen multiple powers.
