Sinestro's History
Thaal Sinestro of Korugar is the arch-nemesis of Green Lantern. At one point the greatest member of the Green Lantern Corps, he was corrupted by his power and exiled for crimes against his own people. He now seeks to impose his own order and control onto the universe, employing a yellow power ring to combat the green he has grown to despise. His prowess and ruthlessness have made him one of the most feared villains in existence, and eventually he establishes his own Sinestro Corps.
Origins
Thaal Sinestro was born on the distant world of Korugar, when he was an adult he became an archaeologist as he was obsessed with the past. One day while on an archaeological dig Sinestro witnessed a space craft crash land near his dig site. Sinestro approached the spacecraft and discovered a mortally wounded alien inside. This alien was wearing a strange ring, which he offered up to Sinestro so he could battle the man that had injured him. At that moment the enemy arrived- a Weaponer of Qward. The Weaponers were a race of aliens from the Antimatter Universe whose culture was focused on war. Sinestro picked up the ring and slipped it on his finger, which instantly transformed Sinestro's clothes into a green suit. Sinestro soon figured out that the ring created whatever he desired as long as he had the will to power it. With this knowledge Sinestro quickly destroyed the Weaponer. When the alien asked for its ring back to he could receive medical attention, Sinestro refused and left the alien to die.
With this new power in his hands Sinestro decided that instead of digging up the past he would instead strive to build for the future. Eventually he was contacted by Abin Sur, another wielder of the green ring. Abin revealed to Sinestro that the ring was worn by all members of the Green Lantern Corps, a intergalactic police force tasked with ridding evil from the universe. Abin brought Sinestro to Oa, the home world of the Green Lantern Corps, to meet the Guardians of the Universe. The Guardians were the creators and leaders of the GLC, and they demanded Sinestro swear the Green Lantern Oath before being accepted into the Corps. Sinestro conceded and was inducted into the Corps, officially becoming a Green Lantern. He was tasked with keeping Sector 1417, which Korugar was situated in, safe from threats.
Sinestro soon became the greatest of the Green Lanterns, often fighting alongside his partner and friend Abin Sur. One day Abin took Sinestro to see his home planet, Ungara, where he met Abin's family. Sinestro soon became infatuated with Abin's sister Arin, and the pair quickly fell deeply in love. Eventually Arin and Sinestro wed, and Sinestro moved back to his home planet with his new bride. While on his home planet he realized that if he stretched his willpower to the limit he could make his world a paradise, an example of what a Green Lantern could really do. He began monitoring communications, populations and heartbeats so that nothing on his home planet would happen without his knowledge. He also created robots out of his willpower to patrol the bustling city of Korugar. Within a few years Sinestro controlled the whole planet, and was eventually named dictator for life.
Sinestro soon had a baby daughter with Arin which they named Soranik. However after threats to the baby were made by disgruntled civilians, Arin gave the baby up for adoption. Sinestro began passing his teachings and philosophies to the new recruits of the Lantern Corps. Arin would begin to resent her husband for what he was doing to his people. Eventually Abin Sur died on a mission and his replacement from Earth named Hal Jordan became Sinestro's new partner. In the same way he did with Abin, Sinestro found a quick friend in Jordan. When Sinestro brought Jordan to his home world, the new Lantern was appalled by what Sinestro was doing to his people.
With the arrival of a new Lantern on their side, the people of Korugar became restless and began rebelling against their overlord. Sinestro was stricken by grief when Arin was killed by a child suicide bomber after his head. Hal Jordan soon reported Sinestro's misconduct to the Guardians of the Universe, causing Sinestro to be stripped of his ring and banished to the Anti-Matter Universe. Other Green Lanterns who believed in Sinestro followed him into the Anti-Matter Universe. Sinestro made a pact with the Weaponers of Qward, who supplied him with a new ring. This ring would channel the yellow light of fear, making Sinestro the first Yellow Lantern. His followers in the Green Lantern Corps would also wield these rings as they became the first members of the Sinestro Corps, wielders of the yellow light.
Green Lantern
Returning to Korugar after the Guardians decide to leave him with the ring, Sinestro learns that his Corps have reverted to their brutal methods, terrorising and slaughtering the people of Korugar rather than ruling it. Sinestro creates a new Green Lantern ring for Hal Jordan, albeit one that he can shut off at will, so that Jordan can help him retake control of the Sinestro Corps, who now want him dead in the belief that his killer will become the new Sinestro Corps leader. After turning various Korugarian prisoners into a temporary Green Lantern Corps using short-lived duplicates of Sinestro's ring, Sinestro and Hal are able to hold off the Sinestro Corps long enough to drain the power away from the Central Power Battery of the Sinestro Corps, de-powering all of the Corps members on Korugar, although those more distant from the battery will still have access to their own power supplies. Later, all Lanterns' rings register that the Sinestro Corps have disbanded with 98% of all known Corpsmen dead or incarcerated, requiring Arkillo, who was cut off from the other Corps in the Orrery with the New Guardians during this attack, to use a new, independent power battery forged by the Weaponer from the fear of the Korugarians. It has since been revealed that the Guardians were responsible for Sinestro acquiring a Green Lantern ring in an attempt to undermine the Sinestro Corps as part of their future plans to destroy all seven Corps. During the conclusion of the "Wrath of the First Lantern" storyline, Sinestro once again becomes a member of the Sinestro Corps after the destruction of Korugar at the hands of Volthoom, and after bonding with Parallax, he reactivates the yellow rings and releases all the Sinestro Corps members who were incarcerated on Oa. Afterwards, he killed every one of the Guardians of the Universe but Sayd and Ganthet, exiling them from Oa instead, and left all of the corps' behind, nothing involving them having any meaning to him any longer with Korugar destroyed.
Forever Evil
Sinestro is revealed to be among the villains split on the idea of how to handle Earth. He is said to have a good relationship with Black Adam. He returns to Earth due to the powerful use of a Qwardian Power Ring by Batman against Power Ring. He later tells Batman that he left himself vulnerable by resisting the bond with the ring, and destroyed Power Ring. Sinestro also mentioned that Batman would make a fine Sinestro Corpsman, vaguely hinting at Batman's experience with the yellow ring of fear in the past.
Return to Prominence
Searching for Remnants
Sinestro would seek to isolate himself from his past as leader of his own corps. The years of fighting both as and against the Green Lanterns, the Guardians of the Universe and their Third Army coupled with the destruction of Korugar at the hands of First Lantern having taken a heavy toll.
The weary cosmic veteran left himself powerless and vulnerable, even with his ring at his side, to the predatory environs of the forgotten space he'd exiled himself too.
He is soon approached by the veritably insane Lyssa Drak; lorespeaker of his former corps whom etched the teachings and predictions of the Book of Parallax into her very body after it was destroyed. Though preferring to remain in his self-imposed banishment, his ring automatically charges itself upon news that the Korugarians still live.
A few of those who hated his rule having escaped some time prior to their world's destruction, an individual few who are still haunted and persecuted to this day by the former Tyrants actions.
Having ascertained this new knowledge from the fanatical acolyte, Sinestro set out to confront his former corps in order to regain control of his empire. A mining outpost on the fringes of the galaxy was jettisoning some of his people as a sacrifice to the Pale Vicars, people whom he'd rescued and taken to the last known outpost of surviving Sinestro Corpsmen.
While acting in a more diplomatic role than when he last had contact with his Corps, violence would ensue as the former leader encountered his replacement: Arkillo. This was further strained when the latter revealed he'd trapped and bound his daughter Soranik, having been tormenting her for days on end.
After a lengthy between his protégé and his selection of soldiers, Sinestro managed to subdue the errant regent and privately went to meet some of the new blood, that being Dez Trevius and Rigen Kale.
Seeing potential within the two, he would use them to lead a Korugarian search party with himself at the helm. Sensing a fellow tactician within Dez, Sinestro's course of conduct would serve a multi pronged purpose; that being finding the missing Korugarians, or leads to their whereabouts, punishing those who would profit off of their abuse and suffering, as well as weeding out any dissenters and potential traitors within the ranks of his peace keeping sect.
Threat of the Paling
While out on patrol for more of his lost people, the Sinestro Corps stopped at a slaver planet where many of Sinestro and Soranik's people were about to be sold off to the highest bidder. Naturally, when the Corps leader approached his would-be refugees, they were hesitant to accept rescue at the hands of another slave driver.
Soranik eventually managed to quell their fears as the other lanterns finished massacring both the rich & entitled, along with their hired help. Celebrations would be cut short however, as the Sinestro Corps were beset by The Paling seconds later.
Godhead
The Sinestro Corps was attacked by the New Gods, and Sinestro declared war on them in retaliation.
Legion of Doom
Sinestro was selected as one of the members of Lex Luthor's Legion of Doom, specifically because of his knowledge of one of the seven forces related with the Totality, the Invisible Spectrum. In fact, in his past, Sinestro helped locking that very power away, but now he will be the one to harness it. Once he took control of the Invisible Spectrum, he converted John Stewart into an Ultraviolet Lantern, and sent him to attack the Justice League. Stewart got himself back in control, but in the meantime Sinestro brought Umbrax, the living black sun who was battery for the Invisible Spectrum, to Earth.
As the Still Force used by Grodd fed on Flash's Speed Force, the membrane separating Umbrax with the Multiverse was destroyed, and the conversion of Earth into an Ultraviolet Lantern started: Sinestro took control of most of humanity, transforming them into Ultraviolet Lanterns. But John Stewart and Martian Manhunter found a way to counter, and made Earth become a White Lantern. Then, Flash was able to access himself the Still Force, and once again he exiled Umbrax.
He then took part in the conflict through time between the forces of Justice and Doom: the Justice League was trying to take pieces of the Totality inside other places in time, to build a Justice version of Lex's own Totality. Cheetah, Grodd and Sinestro were sent back in time to stop John Stewart and the Flash from taking the piece that was stored inside a ship part of the Pearl Harbor fleet. It was the Legion itself that assaulted the American base on the 7th of December, 1941. Battling against both the two members of the League and the Justice Society of America, they were not able to stop them from taking the Totality piece because of the return of Aquaman.
They kept the attack going in Atlantis, but in the end the League was able to send the Totality piece to the present. The League plan failed though, and Doom, with Perpetua, won. Thinking he would finally get his reward for his loyalty, Sinestro was trapped together with the rest of the Legion of Doom inside the Throne of Perpetua, which in truth was Brainiac, to empower Lex with the seven negative forces of the universe.
Death Metal
During the reign of terror of the Batman who Laughs, Sinestro was still trapped into the Throne of Perpetua, but was freed thanks to a combined effort of a Nightwing-led Justice League team and Lex Luthor. Initially ready to kill Lex together with the rest of the Legion, he then decided to follow Luthor again, and helped in the last fight against the Last 52 Multiverse, where he also regained his Green Lantern status after a reconciliation with his greatest rival, Hal Jordan.
