Back to the Green Lantern character sheet.
Beware your fears made into light
Let those who try to stop what's right
Burn like his powernote —Sinestro's might!
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 Wrath of the First Lantern, 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 Necropolis, renaming it "New Korugar" while also taking back command.
- Ax-Crazy: Well over half the team is comprised of violent, unstable psychopaths.
- Bright Is Not Good: Yellow is the brightest color of the primary and secondary colors of any colorspace, and the Yellow Lanterns are made up of Ax-Crazy Knight Templars
- The Dreaded: To be part of the Sinestro Corps, you need to be able to inspire great fear.
- Early Installment Weirdness: When the Sinestro Corps was originally formed, new ring wielders originally gained uniforms that were based on Sinestro's old black and blue costume, and instead of the Corps' symbol they simply had a yellow circle on their chests. They were later supposed to go through a process called a "Fear Lodge," where they were put inside stone rooms, cut off from the rest of the world, and would have to confront their greatest fears in order to ignite the power of their rings. Once that was done, they gained the proper Corps uniform as a symbol of being an official member. Considering the amount of the upheaval the Sinestro Corps' has been through, the lack of mention of the Fear Lodge is understandable, but ring wielders no longer start out with the preliminary uniform when they gain a ring.
- Egocentric Team Naming: They could have been called the Yellow Lantern Corps, but it was named the Sinestro Corps instead.
- Funnily enough, it was actually Booster Gold who inadvertently named the corps during an attempt to distract Sinestro (see Line-of-Sight Name).
- After Sinestro's HeelFace Turn, 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 Conquerors: They use fear to dominate, and several before their transformation were feared dictators.
- Green Lantern Ring: 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.
- HeelFace Turn: After Sinestro re-joined the Sinestro Corps (then called the Yellow Lantern Corps) following Forever Evil, having donned a Yellow ring once more since Wrath of the First Lantern, they have been more "defenders of Korugar" than "oppressors of them and everybody else". When the Green Lantern Corps suddenly vanishes from the universe, Sinestro wastes no time having his Corps take over the role of "universal police", and Soranik does her best to rein in the group's homicidal tendencies. However, once their role is accepted, Sinestro immediately orders them to once more bring terror to the cosmos.
- I Know What You Fear: Sinestro rings can materialize a victim's fears out of energy.
- Kick the Son of a Bitch: 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 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.
- The Last of These Is Not Like the Others: Unlike basically every other color of the spectrum, the yellow light of fear seems be based around if not originating in inflicting fear rather than feeling it. All the corp members are individuals singled out as capable of being highly intimidating, though that may be ring programming.
- Psycho Rangers: A great deal of the initial recruits were basically psychotic, evil counterparts of big name Green Lanterns.
- Red Shirt: A common Sinestro Corps character trait in the 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 Evil Genius 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.
- Shout-Out: You can find a Xenomorph and a Predator and many others in group shots, appropriately enough
- Your Worst Nightmare: 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
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.
You can read his own take on himself here.
- The Ace: Before Hal, he was considered the greatest of the Green Lanterns. It shows, as he has tricks up his sleeve that Hal still hadn't learned, even after over a decade on the job. When it comes to tactical use of the power ring, Sinestro has no equal.
- Adult Fear: Atrocitus was the first to discover Sinestro had a daughter in the first place, and vowed to kill her in retaliation for Sinestro's acts against him. This marked a very rare moment when Sinestro was genuinely afraid.
- Anti-Hero: When written by Geoff Johns he's much more willing to work with the heroes against bigger threats.
- Arch-Enemy: To all Green Lanterns, but Hal Jordan in particular.
- Awesome Ego: Perhaps the greatest example of this in the modern Green Lantern landscape. Despite all the defeats he's suffered over the years, despite his loss during the Sinestro Corps War and his failure to save his planet from Volthoom, Sinestro will still proudly proclaim himself to be the greatest Lantern of them all. His response to Hal telling him that Sinestro isn't any better than Hal is? Laughing in Hal's face and proclaiming "I am better than you".
- Back for the Dead: Sinestro's return during Emerald Twilight part 3. The character had not been seen for years, apart from an appearance as a spirit possessing John Stewart in Mosaic. Yet in what was meant to be Hal Jordan's final issue as Green Lantern, the Guardians seemingly resurrect Sinestro from his imprisonment inside the Central Power Battery in an attempt to stop Hal Jordan's rampage. It doesn't work, as Hal kills him by breaking his neck. Later stories would reveal that the Sinestro that died was a Parallax-created illusion to help break Hal Jordan's will, but at the time this was meant to be the final showdown between Hal and Sinestro.
- Big Bad: For most of the series' existence.
- Breakout Villain: In his first characterization he was a mostly one note villain with some claim to Hals arch-nemesis with not much going to him besides a yellow power ring. Compare that to now, where he along with Atrocitus are the pedestal characters of the lantern corps.
- Characterization Marches On: Initially Sinestro rarely had speaking roles in comics, and was often depicted as a Palette Swap variant of the Joker. Now, he's straddling the line between Anti-Villain and Anti-Hero, despite Word of God saying much of his characterization is based on Adolf Hitler.
- Comic-Book Fantasy Casting: His original looks were based on David Niven. Some fanon said, however that he was an expy of Gamal Abdel Nasser.
- Control Freak: Hal put it best:
- Sinestro wants complete control. Over everything and everybody. And what Sinestro can't control- he destroys.
- Daddy Had a Good Reason for Abandoning You: He gave up his daughter so she wouldn't be persecuted for her father's political ideas. Given what happened to her mother, it was clearly a good call.
- Dark Is Not Evil: The modern take on Sinestro explores this, as far as him wanting to instill "order" throughout the universe as the motive for his villainy, which often plays out like an Evil Plan.
- Dastardly Whiplash: Subverted; he's a villain and has a Snidely-esque whiplash, but his personality is nothing like the villain stereotype.
- Drunk with Power: His initial fall from grace had shades of this and revisiting the issue through flashbacks have only reinforced the idea.
- Even Evil Has Loved Ones: Deep down he still cares for his dead wife Arin Sur, and his daughter Soranik Natu. He also had a very close friendship with Abin Sur, who's dismissal by the Guardians is one of the reasons he hates them.
- Evil Former Friend: To Hal Jordan, who he mentored. The two still respect each other to a degree.Hal: Were we ever truly friends?Sinestro: That's the tragedy of all this, Jordan. Hal. We'll always be friends.
- Eviler Than Thou: During the Red Lanterns' introductory arc, he and Atrocitus spent much of the time boasting in each other's face about being the bigger threat.
- Fallen Hero: Sinestro used to be the single most respected member of the Green Lantern Corps, until he took a shortcut in his work by enslaving his home planet. Just to add to the tragedy, Johns' run suggests that Sinestro didn't just start off a jerk (though he was) who happened to turn evil, but through losing his family to violence on Korugar.
- Friendly Enemy: Claims he and Hal Jordan have always been friends.
- From Nobody to Nightmare: As a young man on Korugar, Sinestro was a simple student of archaeology. Years later, he became a despotic tyrant feared across the stars.
- HeelFace Revolving Door: Between starting off as Lantern, becoming a supervillain, forming his own Corps (that underwent its own FaceHeel Turn eventually), taking part in several Enemy Mine situations- it's not so much what 'side' Sinestro is on as much as what course of action best serves his purpose of bringing order to the universe.
- Heroic Willpower: Though he can't really always be said to be heroic, Ion himself said he had the strongest willpower of all Green Lanterns.
- Hero's Evil Predecessor: Evil Predecessor to either Hal Jordan (greatest Lantern) or Soranik Natu (Lantern of Sector 1417).
- Hijacking Cthulhu: Using both his mastery over fear and his exceptionally strong willpower, he's able to control Parallax, having it possess him and maintaining control, and practically treating it like a pet.
- Interspecies Friendship: He's Korugarian, while his partner, Abin Sur was Ungaran.
- Interspecies Romance: He's Korugarian, while his late wife, Arin Sur, Abin's sister was Ungaran.
- It's All About Me: Sinestro repeatedly shows himself to be incapable of believing that someone else can succeed where he failed, such as automatically concluding that Kyle Rayner's White Lantern ring came from Volthoom rather than accept that Kyle achieved that state on his own, blaming others for his failures rather than accept that he wasn't good enough on his own.
- Jerkass : He May be a Well-Intentioned Extremist but hes still a pretentious condescending asshole who respects very few people (his Archenemy Hal Jordan being one of them). He constantly reefers to Kyle Ranger as an unworthy street rat because of the nature in which he got his powers.
- Kick the Dog: Though he is portrayed more sympathetically as of late, Sinestro does occasionally do this to remind readers that while he might be justified in questioning the Guardians' authority, he is still a villain. He killed Red Lantern Laira just when it seemed like Hal might have calmed her down and taunted Hal about it, and then he later stabbed Ganthet.
- Kick the Son of a Bitch: Slaughtering all the Guardians but Ganthet is horrific, but given this was after they'd taken several major levels in jerkass from Sinestro Corps War onwards, up to and including trying to wipe out all sentient life in the universe... it's not unfair to say they kinda had it coming.
- Knight Templar: Above all, he wishes to bring order to the universe — and he's willing to completely enslave it to do so.
- Laser-Guided Karma: His puppy-kicking is not without consequence. Several members of the Red Lantern Corps, as Atrocitus himself is happy to point out, are victims of Sinestro's corps, making him partially responsible for the rise of the Red Lanterns. And killing Laira drives Hal into such a rage that he is inducted into the Red Lantern Corps himself and comes dangerously close to killing Sinestro and his corpsmen, if not for Saint Walker's intervention.
- A Lighter Shade of Black: He's evil, but he's generally treated as the better man when he fights over villains like Mongul or Nekron.
- Luke, I Am Your Father: He's Soranik Natu's father.
- Manipulative Bastard: Is very charismatic and intelligent, and very good at scheming and manipulating people.
- Meaningful Name: His name is derived from "sinestra", which is Latin for left-handed. It's also an indication he's not a nice guy.
- Names to Run Away from Really Fast: Sinestro. Considering A Sinister Clue, it's pretty clear he's up to no good.
- Never My Fault: He'll never admit that the reason his wife, Arin Sur, turned against him, that his people came to fear him, and that he was stripped of his position as Green Lantern, is all his own fault, due to what borders on a pathological need for control. Instead, he'll constantly blame Hal Jordan, the other Green Lanterns, and the Guardians of the Universe for being too weak or not intelligent enough to understand what's required to bring about order.
- Obviously Evil: He's scarlet-skinned with a Snidely-esque whiplash, and called Sinestro; the only thing shocking about his villainy is that it's well-intentioned.
- The Paragon Always Rebels: He used to be "The Greatest Green Lantern", now he's the Corps' worst enemy.
- Pride: Sinestro's fatal flaw.
- Scary Dogmatic Aliens: If Adolf Hitler had more foresight—and a power ring, and magenta skin—he'd be Sinestro.
- A Sinister Clue: He's left-handed, which is referenced in his name.
- Skunk Stripe: During his time controlling Parallax.
- The Starscream: 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 (which, all things considered, probably isn't far off).
- Took a Level in Badass: Johns has pulled this with a number of characters. Sinestro went from being a good arch-enemy to Hal and already badass to becoming a full-blown Magnificent Bastard.
- Trauma Button: During Blackest Night, Carol zaps him with the standard Star Sapphire technique of putting him in a crystal prison that makes him feel love. Unfortunately, it reminds him of Arin, and Sinestro promptly goes berserk, smashing out of the crystal instantly.
- Villain Has a Point: As shown in full from approximately Blackest Night, through Brightest Day and culminating in Rise of the Third Army and Wrath of the First Lantern, his opinion on the Guardians of the Universe was largely correct.
- Villainous Friendship: Considers Black Adam a friend and peer.
- Well-Intentioned Extremist: Depending on the incarnation, but the comic usually portrays Sinestro as this.
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.
- Ax-Crazy: When you piss him off.
- Berserk Button: 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.
- Boisterous Bruiser: A dark example. Extremely loud and always up for the chance to kill people.
- Character Development: Has received a great deal of this in Green Lantern: New Guardians.
- Deadpan Snarker: For a being who's generally a violent brute, sarcasm is surprisingly common from him.
- The Dragon: Sinestro's right-hand man.
- Drill Sergeant Nasty: 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.
- Evil Counterpart: To Kilowog, the Green Lanterns' drill instructor and fellow hulking alien. They dueled twice in the Sinestro Corps War.
- Guy Gardner sees Arkillo as the Yellow Lantern equivalent to himself.
- Fatal Flaw: 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 isn't capable of measuring up to/surpassing Sinestro's legacy and isn't owning up to it.
- Hidden Depths: 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 Undying Loyalty to Sinestro and why he took Sinestro's betrayal so hard. Time will tell if this is also why Saint Walker has become his Morality Pet after Walker re-grew his tongue.
- I'm a Humanitarian: Fail his tasks and he'll devour you on the spot.
- Insistent Terminology: 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.
- Insult Backfire: 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.
- Last of His Kind: After Sinestro betrayed and disbanded the Corps, Arkillo was the only Yellow Lantern left active. Didn't last for very long, though.
- Leeroy Jenkins: 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 curbstomping the rest of the New Guardians. And yet, in spite of all that, Arkillo is STILL going toe-to-toe with him.
- Lightning Bruiser: Extremely strong, tough, and fast.
- Memetic Badass: Considered this in-universe by his men, who simultaneously fear and revere him.
- Morality Pet: Saint Walker is one for him after he healed Arkillo's tongue. Their relationship grows more and more into this with time spent together. In issue 10 of New Guardians, as Saint Walker continues to fight while saying he'll never give up hope, Arkillo — who is fighting Reach soldiers at the time — tells Walker to "Fear not," which is notable since he's a bloodthirsty killer who gets off on inducing fear and despair but he just told Walker to not be scared. Then in issue 11 of New Guardians, for example, Arkillo is pleased with Saint Walker after he becomes adamant about making Larfleeze pay for the Reach invasion to the Blue Lantern homeworld. He pats Walker's shoulder and comments that he's glad to finally see some fire in Walker's belly.
- The Speechless: After his run-in with Mongul, Arkillo's tongue was ripped out and uses his power ring to communicate. Saint Walker eventually healed him.
- Super Strength: Even without his ring.
- Tongue Trauma: When Mongul ripped his tongue out.
- Took a Level in Kindness:
- Spending time with the New Guardians team has had this effect on him. This can be seen with his relationship with not only Saint Walk (see Morality Pet), but also Carol Ferris, who he doesn't want being insulted. Moreover, he doesn't seem to be as bloodthirsty as he was before joining.
- In Sinestro's solo comic, the Corps heads to Earth to defend it from an invasion of emotion-stealing creatures. After Arkillo protects a mother and daughter from one of the creatures, the little girl tells her mom not to worry because a superhero is protecting them. Arkillo instantly notices this. Shortly afterwards, the Corps heads out to fight some more, but Arkillo opts to stay behind in order to protect the defenseless civilians.
- Undying Loyalty: 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.
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 Blackest Night, his greatest contribution to the war was to shoot the zombie Anti-Monitor in the head and destroy him.
- Bizarre Alien Biology: Bendovian's alien metabolism enables him to survive for centuries in the harsh vacuum of outer space without air, food, or water.
- Cold Sniper: He's sniper and also stoic and humorless to an extreme degree.
- Eldritch Abomination: Considered something pretty close to it in-universe.
- Hero Killer: During the Sinestro Corps War, he was shown to have murdered at least both the Green Lanterns, Barin and Cundiff Cood.
- Improbable Aiming Skills: Can snipe people from three space sectors away.
- Really 700 Years Old: It's been stated that he can go 600 years between meals.
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 Sinestro Corps War, 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.
- The Dreaded: He is considered the deadliest member of the Sinestro Corps.
- Evil Counterpart: To Leezle Pon, another super-intelligent smallpox virus and member of the Green Lantern Corps.
- Frame-Up: He infected Mogo in the form of mushroom spores and used this to Driven to Suicide two Green Lanterns, framing Guy Gardner for murder. But Guy and Soranik Natu found out the truth and freed Mogo from the spore's influence just long enough for Mogo himself to destroy the mother spore.
- Omnicidal Maniac: Even before joining the Sinestro Corps, Despotellis was a genocidal maniac, having killed over three-fourths of the beings in Space Sector 119.
- The Virus: He is a sentient biovirus capable of infecting any living organism and killing it within mere minutes.
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.
- Butter Face: Gave herself a mouth like Mortal Kombat's Mileena.
- Death World: Her homeworld.
- Freudian Excuse: Grew up on a particularly brutal Death World, 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.
- Morality Pet: She has three of them in the forms of her three dead adoptive fathers that are resurrected during Blackest Night.
- Punny Name / Meaningful Name: A play on the word "carousel," as her three animal constructs circle around her like a demonic merry-go-round.
- Raised by Wolves / Wild Child: Her origin story.
- Stringy-Haired Ghost Girl: Sometimes depicted like one.
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.
- Abusive Parents: Subverted. She claims to love all the children she's stolen and says she'd never harm any of them, to the point that even the Star Sapphires believe her love is genuine. But in at least one appearance she deliberately scratched the cheek of Green Lantern Jeryll's child to make Jeryll lower her defenses and kill her, and she generally keeps all her kidnapped charges fed on a liquid which brainwashes them into seeing her as their mother. So while she's not usually physically abusive, she's emotionally and mentally abusive because she makes those children love her.
- Adult Fear: She's a monster right out of Grimm's fairy tales.
- And I Must Scream: Was among those female Sinestro Corpsmen the Star Sapphires attempted to convert via crystal prisons. As she was in their custody during the Blackest Night and its lead-up, however, she was forced to hear the voices of her stolen children as they were abducted by Black Lanterns while unable to do anything about it. This causes her to cry, and Miri Riam feels a moment of Sympathy for the Devil.
- Body Horror: The "cage" on her back isn't just an inverted ribcage. It has nipples for her stolen children to suckle.
- Invasion of the Baby Snatchers: She was believed to just be a ghost story parents told their children, but she is a very real monster and, in a twist of irony, the parents have more reason to be afraid of her than the kids.
- Mama Bear: Would you believe she genuinely loves and is protective of the children she steals?
- Mind Control: Whatever kind of milk she secretes has this effect, convincing whoever partakes that she is in fact their mother.
- Morality Pet: The kids she steals. She was not happy when they were missing.
- Nice Job Breaking It, Hero!: The Black Corphans were the direct result of nobody bothering to ask her where her children were. Which basically means the Green Lanterns and Zamarons were responsible for the mass starvation of thousands of innocent children of their own deceased comrades. Although Star Sapphire Miri points out if Kryb hadn't murdered their parents and kidnapped the children in the first place, they'd still be alive.
- Psychic Powers: Not that it's heavily expanded upon, but her milk apparently creates a telepathic connection between her and those who ingest it, which implies some level of Mind Control and Telepathy on her part.
- Punny Name / Meaningful Name: She's a crib.
- Stringy-Haired Ghost Girl: Has the hair for it, at least.
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 Brightest Day, Krona freed her and recruited her for his plans.

- Chained by Fashion: The Book of Parallax is kept chained to her wrist.
- Does Not Like Shoes: Though originally shown in a pair of evil go-go boots, her every appearance since has been barefoot.
- FaceHeel Turn: After Krona freed her, she turned against Sinestro for knowledge and not being rescued. She eventually came back around, though.
- Green-Skinned Space Babe: An hot alien babe with blue skin.
- Hot Librarian: She qualifies as this, since she keeps the Book of Parallax
- Humanoid Abomination: If she wasn't one before, she's definitely one in Brightest Day.
- Long-Lost Relative: Her surname implies she's a distant relation to Shadow Lass of the Legion of Super-Heroes.
- Mad Oracle: An insane oracle recruited for her lack of weaknesses and ability to inspire fear.
- Meaningful Name: You need Bilingual Bonus. "Lyssa" sounds sexy but it's Greek and means "rabies".

- Ms. Fanservice: A scantily-clad blue-skinned babe and also an Hot Librarian.

- Thong of Shielding: Her sinister attire.
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 Sinestro Corps War, Parallax possessed Kyle Rayner for a brief time.
- Anthropomorphic Personification: Of the yellow light of fear, and fear itself by extension.
- Arch-Enemy: The Spectre.
- Ax-Crazy: Batshit insane bug whose personality is full of malice.
- Badass Boast: Makes several to the Spectre during Rebirth and Blackest Night.
- "You are more likely to eradicate the color yellow from reality than you are to eradicate me, Black Lantern."
- Berserk Button: Does not take kindly to the idea that it fears anything, especially Hal Jordan.
- Big Creepy-Crawlies: Its true form evokes this, mixed with a little dragonfly and serpent/eastern dragon. Though the extent of this does depend on the artist.
- Body Horror: Tends to do this to its hosts, with the tamest example being how it likes to give them grins with More Teeth than the Osmond Family
- Card-Carrying Villain: While the Sinestro Corps as a whole may hover somewhere around Knight Templar-hood, Parallax itself is utterly and gleefully Chaotic Evil, with absolutely no redeeming features or any real goals other than spreading fear.
- Civilization Destroyer: The reason the Guardians had to seal it away. In the past, any planet it landed on would have its civilisations collectively driven insane by fear, which Parallax would feed off until they ultimately destroyed themselves.
- The Corrupter: Was responsible for Hal Jordan's descent into insanity and subsequent villainy by influencing his mind from inside the Central Power Battery. And when Krona returns it to the Central Battery to control all the Green Lanterns during Brightest Day, even though the Earth Lanterns (plus Kilowog and Ganthet) are able to resist being outright controlled, its influence almost turns them against one another anyway.
- Demonic Possession: What happens when he possesses people.
- The Dragon: To Sinestro in Sinestro Corps War and Krona in Brightest Day.
- Eldritch Abomination: It looks like a cross between a giant dragonfly and a serpent.
- Emotion Eater: Comes with being the embodiment of fear.
- Energy Being: His body.
- Evil Counterpart: To Ion.
- Eviler Than Thou: It makes itself clear that while it may be a member of the Sinestro Corps, it owes them no loyalty and they will die if they get in its way.
- Faux Affably Evil: At least acted this way towards Kyle Rayner when it had an internal conversation with his mind.
- From Nobody to Nightmare: Parallax used to be nothing more than an ordinary little bug... before it became the first being to experience fear.
- The Heartless: Embodiment of all fear.
- Last of His Kind: The only non-humanoid (as with Black Hand) emotional entity not sealed into the Source Wall as of the end of "Light's Out". It couldn't care less.
- Light Is Not Good: Quite possibly the ultimate example of this, being both an embodiment of light and also completely evil.
- Lovecraftian Superpower: During Sinestro Corps War, we got a lovely look into what Parallax can do to its host's bodies: most prominently, while possessing Kyle Rayner, it turned his chest into a mass of yellow tendrils so it could absorb Hal Jordan.
- When a host is freed from its control, the usual way of portraying this is that both of them are literally ripped out of the 'merged' body, which is then discarded as a husk of skin and teeth and yellow goo on the ground. It's even less pretty than it sounds.
- Omnicidal Maniac: In case that time it made Hal Jordan destroy the universe wasn't enough proof:Spectre: You will be destroyed...Parallax: No. I believe that's everyone else.
- Physical God: Anyone it possesses will essentially become this. Interestingly, it's implied that Parallax itself becomes much more powerful with a host, even if the host doesn't have any superpowers of their own. It is described as a 'parasite', after all.
- Psycho Ex-Girlfriend: Disturbingly, it tends to come off as this towards Hal, referring to him as its 'special someone'.
- Sealed Evil in a Can: Green Lantern: Rebirth revealed that the long-established "yellow impurity" in the Central Power Battery was actually Parallax, the "yellow fear entity," an insectile manifestation of that emotion, released when Hal "Greatest GL of them All" Jordan entered the Central Battery years before. Before that, 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.
- Slasher Smile: Its default expression. It only really drops it when it's angry.
- The Only One Allowed to Defeat You: It saved The Spectre from the Black Lanterns just so they could have a proper rematch.
- Villain Decay: Since the New 52, Parallax has been not so much a villain of its own as much as a tool for greater power over yellow energy, with its 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 precious Hal".
Ranx the Sentient City
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.

When he dig up his father body with Hal Jordan and he goes on to say how he should have been different and how his father was never there for him, and it the Green Lantern Corp fault. Hal Jordan had No Sympathy point out not having a father did not excuse his crimesAmon Sur Things should have been different. I should have been different. My father was never there for me. He was never there because of the damn Green Lantern Corps. What I become for so long was their fault.Hal Jordan You got to be kidding me. You don't get a free pass because your father wasn't there.

- Evil Twin: Inverted. Maash is in fact a set of triplets that merged into one in their mother's womb. The bottom two heads are in control all the time and are the actual monsters. The very top head is completely innocent and has no ability to stop his siblings.
- Multiple Head Case: Three heads stacked atop each other.

- Expy: He's a purple-skinned version of the Incredible Hulk.
