The Sinestro Corps are fueled by fear the way Green Lantern rings are fueled by willpower and their powers are very similar, including flight, constructs and communication. Whereas the Green Lanterns seek to bring order to the universe by promoting justice, the Sinestro Corps want to rule the universe through fear.

Since Sinestro was drafted back into the Green Lanterns, his corps have gone rogue without his rule to keep them in line. When Sinestro discovered that they had taken over his home planet of Korugar, he forcibly disbanded them, and most of the Corps were captured or killed in the aftermath.

With the destruction of Korugar in ''ComicBook/WrathOfTheFirstLantern'', Sinestro has left his Corps with Parallax, leaving Arkillo in charge of the renamed "Yellow Lantern Corps", though he did eventually come back and bring the survivors of the planet's destruction to [[IDontLikeTheSoundOfThatPlace Necropolis]], renaming it "New Korugar" while also taking back command.

* AxCrazy: Well over half the team is comprised of violent, unstable psychopaths.
* TheDreaded: To be part of the Sinestro Corps, you need to be able to inspire great fear.
* EgocentricTeamNaming: They could have been called the Yellow Lantern Corps, but it was named the Sinestro Corps instead.
** Funnily enough, it was actually ComicBook/BoosterGold who inadvertently named the corps during an attempt to distract Sinestro (see LineOfSightName).
** After Sinestro's HeelFaceTurn, Arkillo's in charge, and wants to change the name because of the betrayal, now wanting to be called the Yellow Corps. or the Fear Corps.
* {{Galactic Conqueror}}s
* GreenLanternRing: Yellow power rings work pretty much exactly like their green counterparts, with the addition of being able to sense their opponents' fears and project them as energy constructs.
* HeelFaceTurn: After Sinestro re-joined the Sinestro Corps (then called the Yellow Lantern Corps) following ''ComicBook/ForeverEvil'', having donned a Yellow ring once more since ''ComicBook/WrathOfTheFirstLantern'', they have been more "defenders of Korugar" than "oppressors of them and everybody else".
* IKnowWhatYouFear: Sinestro rings can materialize a victim's fears out of energy.
* KickTheSonOfABitch: Their depredation of Daxam while under Mongul II's control was absolutely brutal, with wholesale slaughter and the enslavement of the few survivors that they left being the order of the day. That being said, Daxam was one of the most [[AbsoluteXenophobe xenophobic]] planets in the galaxy, with a cultural belief that they were the lone civilized species and that anything else was a mud race deserving of extinction. Sodom Yat was practically the only Daxamite who ''wasn't'' like this, and his disgust for the rest of his species was so great that he very nearly just left it to Mongul II and the rest of the Corps to tear apart.
* PsychoRangers
* RedShirt: A common Sinestro Corps character trait in the ComicBook/{{New 52}}. In the opening arc of the relaunched Green Lantern book, any Sinestro Corps character introduced that was not existent from the group's inception, from the hunter sent after Sinestro in issue 2 to EvilGenius Professor Insidd, was killed off before the arc's conclusion. Meanwhile, most of the established Yellow Lanterns were said to have been forced into a hibernating state.
* ShoutOut: You can find a [[Franchise/{{Alien}} Xenomorph]] and a Franchise/{{Predator}} and many others in group shots.
** And [[FridgeBrilliance fitting, to boot]]: where else would horror movie monsters find a home than the Corps of Fear?
* YourWorstNightmare: Members are first initiated by experiencing their worst fear in a "fear lodge", then they get the ability to weaponize others' worst nightmares.

!Notable Sinestro Corps Members

!!Thaal Sinestro
->'''Homeworld:''' Korugar

Sinestro was a former Green Lantern who carried out his oath through the use of tyranny. When exposed, Sinestro was brought in by Hal and imprisoned in the Battery. There, he made contact with Parallax, a living yellow parasitic embodiment of fear. Years later, after his plot against Hal Jordan had run its course, he retreated to the Anti-Matter universe and built a Yellow Power Battery, making him the first to harness one of the new colors to form a Corps.

* ArchEnemy: To all Green Lanterns, but Hal Jordan in particular.
* BigBad: For most of the series' existence.
* ComicBookFantasyCasting: His original looks were based on [[http://en.wikipedia.org/wiki/David_Niven David Niven]]. Some fanon said, however that he was an {{expy}} of [[http://en.wikipedia.org/wiki/Gamal_Abdel_Nasser Gamal Abdel Nasser.]]
* DastardlyWhiplash: At least in appearance.
* HerosEvilPredecessor: Evil Predecessor to either Hal Jordan (greatest Lantern) or Soranik Natu (Lantern of Sector 1417).
* FromNobodyToNightmare: As a young man on Korugar, Sinestro was a simple student of archaeology. Years later, he became a despotic tyrant feared across the stars.
* TheParagonAlwaysRebels
* ScaryDogmaticAliens: If UsefulNotes/AdolfHitler had more foresight--and a power ring, and magenta skin--he'd be Sinestro.
* TheStarscream: Back when he was still a Green Lantern. He had major plans to dethrone and murder his superiors, the Guardians, due to his belief they were doing a poor job running the universe ([[JerkassHasAPoint which]], [[Comicbook/BlackestNight all]] [[ComicBook/BrightestDay things]] [[ComicBook/RiseOfTheThirdArmy considered]], [[JerkassHasAPoint probably isn't far off]]).
* VillainHasAPoint: As shown in full from approximately ComicBook/BlackestNight, through ComicBook/BrightestDay and culminating in ComicBook/RiseOfTheThirdArmy and ComicBook/WrathOfTheFirstLantern, his opinion on the Guardians of the Universe was largely correct.
* WellIntentionedExtremist: Depending on the incarnation, but the comic usually portrays Sinestro as this.

->'''Homeworld:''' Vorn

Sinestro's right-hand man and most loyal supporter. Arkillo was the first being Sinestro chose to join the Sinestro Corps, and he quickly proved his worth as a leader and taskmaster. The hulking, ogre-like alien is the Corps' main drill sergeant and overseer of the ring forges. After the Sinestro Corps War, when Sinestro was imprisoned on Oa, Arkillo led the faction that remained loyal to him; he challenged the usurper, Mongul, for control of the Corps, but lost and had his tongue ripped out as punishment. Following Sinestro's return, Arkillo resumed his old duties.

Arkillo was off with the New Guardians when the Corps went rogue and Sinestro disbanded them, and was incredibly angered at Sinestro's apparent betrayal. The Weaponer provided him with a new (albeit likely flawed) battery, and Arkillo now serves no one but himself and the Yellow Light.

* AxCrazy: When you piss him off.
* {{Badass}}: Sure, he lost to Mongul II in the end, but the fact that he was able to hold his own against him is pretty impressive. So is repeatedly being able to go toe-to-toe with Kilowog.
** Oh, he's upped the ante even further. When the New Guardians encounter Invictus, a terrifyingly powerful archangel, what does Arkillo do? ''He charges right at him and decks him.'' Oh, and keep in mind that Invictus was otherwise [[CurbStompBattle curbstomping]] the rest of the New Guardians. And yet, in spite of all that, Arkillo is STILL going toe-to-toe with him. If this doesn't cement him as one, nothing does.
* BerserkButton: If you either mention Mongu-er, the M-word around him or ask about his necklace, he'll kill you on the spot. No questions asked.
* BoisterousBruiser
* CharacterDevelopment: Has received a great deal of this in ''Green Lantern: New Guardians''.
* DeadpanSnarker: For a being who's generally a violent brute, sarcasm is surprisingly common from him.
* TheDragon: Sinestro's right-hand man.
** DragonAscendant: With Sinestro's HeelFaceTurn, Arkillo's in charge of the Corps. Unfortunately he's one of the few left.
* DrillSergeantNasty: If you fail his tasks in any way, shape, or form, he'll devour you then and there. Well, that's how he used to be; he's become ''far'' more reasonable since his life fell apart and he was forced to rebuild everything.
* EvilCounterpart: To Kilowog, the Green Lanterns' drill instructor and fellow hulking alien. They dueled twice in the ComicBook/SinestroCorpsWar.
* FatalFlaw: Although he believes his ring isn't working correctly, according to Carol the reason it isn't working is because (ironically) he's afraid that he [[InadequateInheritor isn't capable of measuring up to/surpassing Sinestro's legacy]] and isn't owning up to it.
* HiddenDepths: He's always been portrayed as a bloodthirsty, murderous savage, but it was recently revealed by Carol Ferris that Arkillo actually loves Sinestro and is afraid he'll never measure up to him. Though it's not yet known if his love for Sinestro is in a romantic way or if it's loving him as a fatherly figure (Carol mentions him having "daddy issues"), it helps explain his UndyingLoyalty to Sinestro and why he took Sinestro's betrayal so hard. Time will tell if this is also why Saint Walker has become his MoralityPet after Walker re-grew his tongue.
* ImAHumanitarian: Fail his tasks and he'll devour you on the spot.
* InsistentTerminology: Now that he's the leader of the Sinestro Corps, Arkillo would rather have the corps be called Yellow Lanterns or Fear Lanterns, as Sinestro betrayed them.
* InsultBackfire: When the Archangel defeats several members of different Corps. he advances on Saint Walker and Arkillo, saying that they're more black hearts, Arkillo lunges at him saying "The Blackest".
* JerkAss: During the Corps' initial run, he was an absolutely brutal and merciless drill sergeant who felt that fear was the best motivator and would keep lower-ranked members in line with the threat of being devoured alive. After his life fell apart and he had to rebuild everything, he became a hell of a lot more reasonable.
* LastOfHisKind: After Sinestro betrayed and disbanded the Corps, Arkillo was the only Yellow Lantern left active.
* LightningBruiser
* MemeticBadass: Considered this in-universe by his men, who simultaneously fear and revere him.
* MoralityPet: Saint Walker is sort of one for him after he healed Arkillo's tongue. It's still in the works though.
** It does seem to grow more the more time they spend together. In issue 11 of New Guardians, Arkillo is quite pleased with Saint Walker after Walker becomes very adamant about making Larfleeze pay for the Reach invasion to the Blue Lantern homeworld, [[spoiler:which, it turns out, Larfleeze was not responsible for after all]]. He pats Walker's shoulder (quite hard) and comments that he's glad to finally see some fire in Walker's belly. He still seems unable to stop calling Walker "Blue Worm" from time to time, though.
** Even before that, during the Reach invasion in issue 10, as Saint Walker continued to fight while saying he'd never give up hope, Arkillo, who was at the time attacking Reach soldiers, told Walker to "Fear not". A bloodthirsty killer who basically gets off on inducing fear and despair on others, just told Walker to not fear while he fought the invaders alongside him.
* TheSpeechless: After his run-in with Mongul. Saint Walker eventually healed him.
* SuperStrength: Even without his ring.
* TongueTrauma: When Mongul ripped his tongue out.
* TookALevelInKindness: As hard as it may seem to believe, but it seems spending time with the New Guardians team has had this effect on him. Not only as seen with Saint Walker, now to the point of having actually polite conversations with him, but it can also be seen with Carol Ferris, as he warns Jediah Caul to be very careful with what he says when Caul is about to insult Carol. Even outside his interactions with the team, as he seems to be not as bloodthirsty as before.
** In Sinestro's solo comic, the Corps head to Earth to defend it from an invasion of emotion stealing creatures (and even manage to recruit heroes and villains from Earth into the Corps to help out). When Arkillo protects a mother and daughter from one of the creatures, the little girl, with absolutely no fear of Arkillo's appearance, tells her mom not to worry because a superhero is protecting them, which Arkillo instantly notices. Shortly afterwards, the Corps head out to fight some more, but Arkillo opts to stay behind to protect the defenseless civilians.
* UndyingLoyalty: He's pretty much a very violent and barbaric brute, but he is also fiercely loyal, namely being Sinestro's most loyal Corps member. He's also been showing this towards Saint Walker after the latter used his ring to re-grow Arkillo's tongue, first by trying to protect him from Invictus (though he finds it difficult to actually voice the word "friend" when referring to Walker) and then by quickly and with no hesitation coming to help Walker and the Blue Lantern corps fight against the forces invading their home planet.

->'''Homeworld:''' Unknown

A mysterious being resembling a hermit crab, Bedovian usually drifts through space, emerging from his shell only to feed. He was recruited by the Sinestro Corps, as their sniper. It was noted by Lyssa Drak that unlike the others, he did not have to train to conquer his own fears, as the centuries of isolation within his shell had numbed him to all emotion.

He was defeated in battle by John Stewart, who managed to figure out where he was and snipe him back. He survived, and in the ''ComicBook/BlackestNight'', his greatest contribution to the war was to shoot the zombie Anti-Monitor in the head and destroy him.

* ColdSniper: Can snipe people from ''three space sectors away''. He's also stoic and humorless to an extreme degree.
* EldritchAbomination: Considered something pretty close to it in-universe.
* ImprobableAimingSkills
* ReallySevenHundredYearsOld: It's been stated that he can go 600 years between meals.
** BizarreAlienBiology: He won't go hungry for a while.

->'''Homeworld:''' Unknown

A sentient virus recruited into the Sinestro Corps. Even before joining the Sinestro Corps, Despotellis was a genocidal maniac, having killed over three-fourths of the beings in Space Sector 119. Sinestro used Despotellis to murder Maura Rayner, using her death to break her son Kyle's will to make him susceptible to possession by Parallax. During the ''ComicBook/SinestroCorpsWar'', Despotellis infected Guy Gardner, but it was defeated by his counterpart in the Green Lantern Corps, the sentient smallpox virus Leezle Pon, whose partner Despotellis had killed. Despotellis is currently in custody on Oa.

* ArchEnemy: To Leezle Pon.
* EvilCounterpart: To Leezle Pon.
* TheVirus

!! Karu-Sil
->'''Homeworld:''' Graxos III

Born on a harsh jungle world, Karu-Sil was orphaned by a rival tribe. She was soon taken in by a small pack of predators, eventually thinking of herself as one of them and mutilating her mouth to look more like them. Eventually, a Green Lantern named Blish found her and killed her "fathers", thinking they were threatening her, and she was institutionalized until her yellow ring found her. She's now constantly accompanied by yellow constructs in the form of her pack.

Sometime after the Sinestro Corps War, Karu-Sil and several other female members of the Sinestro Corps are captured by Zamarons. Her body along with the two others are shown to the Guardians and Green Lantern Corps who visit the home world of the Zamarons. The trio are being subjected and conditioned to be members of the Star Sapphire Corps. The impurity of the subject to instill fear being eliminated, replaced by love it was not finished as she was released by Sinestro. During the Blackest Night, Karu-Sil was attacked by the corpses of her pack, reanimated as Black Lanterns. Although initially unwilling to fight her "fathers", she was convinced by a passing Green Lantern to join her light with him and destroy them. She then killed the Green Lantern herself.

* ButterFace: Gave herself a mouth like ''Franchise/MortalKombat'''s Mileena.
* DeathWorld: Her homeworld.
* FreudianExcuse: Grew up on a particularly brutal DeathWorld, saw her entire family killed by a rival tribe, saw her adoptive family killed by a Green Lantern who had no clue what the fuck he was doing, and was thrown into an institution where she languished for some time until her ring found her. Given the sheer horror of her entire existence, it's a wonder that she wasn't drafted by the Red Lantern Corps instead.
* MoralityPet: She has three of them in the forms of her three dead adoptive fathers that are resurrected during ComicBook/BlackestNight.
* PunnyName / MeaningfulName: A play on the word "carousel," as her three animal constructs circle around her like a demonic merry-go-round.
* RaisedByWolves / WildChild
* StringyHairedGhostGirl: Sometimes depicted like one.

!! Kryb
Kryb kills parents she views as unworthy and takes their baby children as her own, keeping them in the cage growing out of her back. Since joining the Sinestro Corps, she has begun targeting the children of Green Lanterns.

During the Blackest Night, Kryb escaped Zamaron, and convinced Miri Riam into helping her find her children, who had become the Black Lantern Corphans. She found them attacking Oa, being destroyed by a Red Lantern Guy Gardner. She attempted to stop him, during which time Gardner tore off one of her arms and rammed it down her throat. She is however, later seen when all of the Lantern Corps assembled over the Earth to fight Nekron, and is seen fighting the Black Lanterns of Xanshi.

* AbusiveParents: Ironically averted, but she's certainly abusive to the parents.
* AdultFear: She's a monster right out of Grimm's fairy tales.
* BodyHorror: The "cage" on her back isn't just an inverted ribcage. It has [[{{Squick}} nipples for her stolen children to suckle.]]
* InvasionOfTheBabySnatchers
* MamaBear: Would you believe she genuinely loves and is protective of the children she steals?
* MindControl: Whatever kind of milk she secretes has this effect, convincing whoever partakes that she is in fact their mother.
* MoralityPet: The kids she steals. She was not happy when they were missing.
* NiceJobBreakingItHero: [[spoiler: The Black Corephans]] were the direct result of nobody bothering to ask her where her children were. [[spoiler: Which basically means the Green Lanterns and Zamorans were responsible for the mass starvation of thousands of innocent children of their own deceased comrades.]]
* PunnyName / MeaningfulName: [[DontExplainTheJoke She's a crib.]]
* StringyHairedGhostGirl: Has the hair for it, at least.

!!Lyssa Drak
->'''Homeworld:''' Talok VII

The Keeper of The Book of Parallax, she records the history of the Sinestro Corps in its pages. Her past is unknown, but she is incredibly loyal to Sinestro and her leader obviously trusts her with their group's greatest secrets. She also supervises the final test for membership: a potential recruit is locked in a Fear Lodge, a sealed box of absolute darkness, with an uncharged power ring. If they can overcome and master their own fears, they can ignite their ring and escape. Failure means death from thirst, starvation, suffocation, or suicide. She noted with interest the example of Bedovian mentioned above, and she unexpectedly gave Amon Sur a bit of encouragement by reading to him the tales of the others before him.

She was arrested and imprisoned on Oa, but broke free from her cell during a prison riot. While searching for her book, she found the mysterious Book of the Black, only for the Guardian known as Scar to trap her within it. During ''ComicBook/BrightestDay'', [[spoiler: Krona]] freed her and recruited her for his plans.

* AbsoluteCleavage
* AndIMustScream: When she was trapped in The Book of the Black.
* BadassBookworm
* BadassCape
* [[GreenSkinnedSpaceBabe Blue Skinned Space Babe]]
* ChainedByFashion: The Book of Parallax is kept chained to her wrist.
* DoesNotLikeShoes: Though originally shown in a pair of evil go-go boots, her every appearance since has been barefoot.
* FaceHeelTurn: After Krona freed her, she turned against Sinestro for knowledge and not being rescued. [[HeelFaceRevolvingDoor She eventually came back around, though.]]
* HotLibrarian
* HumanoidAbomination: If she wasn't one before, she's ''definitely'' one in ''Brightest Day''.
* LongLostRelative: Her surname implies she's a distant relation to Shadow Lass of the ComicBook/{{Legion of Super-Heroes}}.
* PointyEars
* TheStoryteller: Lyssa loves to tell stories about her corps to anyone willing to listen. When she gets interrogated by some [=GLs=], she only tells them stories about the corps.
* {{Stripperific}}
* [[HumanNotepad Talokite Notepad]]: In the aftermath of Wrath of the First Lantern, Lyssa senses that the Book of Parallax has been destroyed, and proceeds to use her ring to burn it all into her skin from memory.
* TomeOfEldritchLore: The Book of Parallax holds the life story of every member of the Sinestro Corps, and every atrocity they have done in the name of fear.
* ThongOfShielding

->'''Homeworld:''' Qward (originally Earth)

The Fear Entity--the embodiment of the Yellow Light, given life and strength from the fear of every sentient being. It was born when early life experienced fear for the first time. The Guardians bound it on Maltus eons ago, until it was released by Larfleeze. Eventually, the Guardians ended Parallax's reign of terror by trapping it in the Central Power Battery on Oa, where it stayed for countless ages until everyone, even the Guardians themselves, forgot about its existence. Parallax ''was'' the Yellow Impurity that prevented Green Lantern rings from affecting the color yellow.

Like Ion, Parallax can possess a living host, but it either dominates them completely or subtly manipulates their actions. Hal Jordan was its best-known host, through whom Parallax destroyed the Green Lantern Corps and nearly remade the entire universe. During the ''ComicBook/SinestroCorpsWar'', Parallax possessed Kyle Rayner for a brief time.

* ArchEnemy: ComicBook/TheSpectre.
* AxCrazy
* DemonicPossession
* TheDragon: To Sinestro in ''Sinestro Corps War'' and [[spoiler: Krona]] in ''ComicBook/BrightestDay''.

* EmotionEater: Comes with being the embodiment of fear.

* FauxAffablyEvil: At least acted this way towards Kyle Rayner when it had an internal conversation with his mind.
* FromNobodyToNightmare: Parallax used to be nothing more than an ordinary little bug... before he became the first being to experience fear.
* TheHeartless: Embodiment of all fear.
* LastOfHisKind: The only non-humanoid (as with Black Hand) emotional entity not [[spoiler:sealed into the Source Wall]] as of the end of "Light's Out". It couldn't care less.
* SealedEvilInACan: ''Green Lantern: Rebirth'' revealed that the long-established "[[KryptoniteFactor yellow impurity]]" in the Central Power Battery was actually ''Parallax'', the "yellow fear entity," an [[AnthropomorphicPersonification insectile manifestation]] of that emotion, released when Hal "Greatest GL of them All" Jordan entered the Central Battery years before. Before it was in a box that was stolen from Maltus by Larfleeze and his crew. Later it was imprisoned in a Sciencell, and finally got ripped apart and stashed in four separate batteries.
* TheOnlyOneAllowedToDefeatYou: It saved ComicBook/TheSpectre from the Black Lanterns just so they could have a proper rematch.
* VillainDecay: Since the ComicBook/{{New 52}}, Parallax has been not so much a villain of his own as much as a tool for greater power over yellow energy, with his own personality having been ignored for the most part.
* {{Yandere}}: Shows some elements of this to Hal, wanting to use him as a host again and sometimes calling him "my Hal".

!!Ranx the Sentient City
->'''Homeworld:''' Ranx

One of the most powerful of the Sinestro Corps, Ranx is an interstellar city the size of a moon. Its origins are unknown, but it is said to be as old as the stars. The circuitry running through it allows it to be aware of every activity on its surface, and it can manipulate its own landscape and gravity, similar to Mogo. Ranx's only inhabitants were criminals and drifters, but it developed a grudge against the Green Lanterns for attacking it and taking them away. The other Sinestro Corps members used Ranx as a base and training ground, similar to Mogo and the Green Lanterns.

An ancient prophecy decreed that Ranx would destroy Mogo, but Sodam Yat defeated it and blew it up. Ranx has survived shutdowns and destruction before, and it may rise again.

* ArchEnemy: Very fixated on Guy, owing to their previous encounter in which Guy detonated a bomb in Ranx's sewers, causing the city to "void it's bowels".
* EvilCounterpart: To Mogo.
* GeniusLoci
* MalevolentArchitecture
* ShoutOut: To the [[StarWars Death Star]].
