->''"In Blackest Day, In Brightest Night\\
Beware your fears made into light\\
Let those who try to stop what's right\\
Burn like his power... Sinestro's might!"''
-->-- '''[[AlwaysChaoticEvil Sinestro Corps]] Oath'''

''Sinestro Corps War'' is a 2007 comic book storyline published by Creator/DCComics. The storyline is a BatFamilyCrossover for the ''ComicBook/GreenLantern'' franchise, spanning ''ComicBook/{{Green Lantern|2005}}'' #21-25, ''ComicBook/GreenLanternCorps'' #14-18, a prologue in the form of ''Green Lantern: Sinestro Corps Special'' #1, and a single tie in with ''ComicBook/BlueBeetle'' #20.

Following his defeat, Sinestro has retreated back to Qward, where he has taken over and started to amass an army of Yellow Lanterns capable of "instilling great fear." Modeling his army after the Green Lantern Corps and allying himself with the Anti-Monitor, he launches an all out war against the Green Lanterns.

The story entered production in 2006 and was released in June 2007. It proved to be a massive success, financially and critically. Fans consider it among the best Green Lantern stories and it is easy to see why. It introduced new storyline concepts including the variously colored Lantern Corps and the emotional spectrum.

----
!!''Sinestro Corps War'' provides examples of:
* AllThereInTheManual: The ''Green Lantern/Sinestro Corps Secret Files and Origins'' special has informative bios on every member of both Corps. This includes the names, homeworlds, Space Sectors and backstories of Corpsmen who either appeared only in crowd shots during this storyline or were [[WeHardlyKnewYe abruptly killed off before there was a chance to know them better]].
* AnthropomorphicPersonification: It's established that "Ion" is actually the embodiment of willpower, just as Parallax is the embodiment of fear. The rest of the emotional spectrum weren't covered for some time.
* AnArmAndALeg: When Risk attempts to take revenge of Superman-Prime for tearing off his arm during ''ComicBook/InfiniteCrisis'', Superman-Prime responds by tearing off his left arm.
* ArtEvolution: Ethan Van Sciver overhauled Sinestro's character model from ''Rebirth'', with his new look taking influence from Hitler and the Nazis to hammer home the fascism undertones.
* AscendedExtra: Many of the Sinestro Corps members. An example? Low and Maash have their own action figures now. "Who are Low and Maash?" you ask? They appear in the background of a few scenes.
* AscendedMeme: It didn't quite reach meme levels, but there's a rooftop fight with the sound effect "eepaa". The sound effect's origin? A one off gag in ''WesternAnimation/TheSimpsonsMovie''. (This is acknowledged as such in the commentary in the back of ''The Sinestro Corps War Volume Two''.)
* AsLongAsThereIsEvil: Sinestro makes this boast while he, Hal, and Kyle fight.
--> '''Sinestro:''' As long as there is life, the universe will never be without fear!
* BadGuysDoTheDirtyWork: Just like ''ComicBook/CrisisOnInfiniteEarths'', everything the heroes throw at the Anti-Monitor won't bring him down until [[spoiler:the Anti-Monitor's OWN TEAMMATE Superboy-Prime disposes of him in revenge for the death of his Earth]].
* BeatThemAtTheirOwnGame: [[MilitarySuperhero John]] forms a sniper rifle construct to take on Bedovian.
* BigDamnHeroes: ''Repeatedly.'' The Lost Lanterns on Qward, Kilowog's squad on Mogo, John and Guy on Qward...
* BreakoutCharacter: The Green Lantern franchise as a whole, in the larger DC universe. Most directly, ''Sinestro Corps''' success got its sequel ''ComicBook/BlackestNight'' expanded from a BatFamilyCrossover to a full-blown CrisisCrossover.
** The series also cemented Sinestro as one of the top villains in the DCU.
* BringIt: After Hal, Kyle and Sinestro have all had their rings drained and end up on a rooftop, Sinestro just glares at them. "Come on, then. The both of you."
* CListFodder: Particularly [[spoiler:Jack T. Chance]], who Geoff Johns admits was killed for being "Guy Gardner-lite".
* ColdSniper: Bedovian
* ColonyDrop: When discussing how to defeat the Anti-Monitor:
-->'''John:''' That'd take the grenade the size of a moon.\\
'''Guy:''' Hey, Johnny Boy... ''[points to Warworld]'' ...what do ya think ''that'' is?
* ColorCodedForYourConvenience: Obviously, but subverted by Parallax, who wears green while possessing Kyle.
* CombatBreakdown: Sinestro vs. Hal and Kyle, after all three get their rings drained.
* CostumeEvolution: The Sinestro Corpsmen uniforms have also been overhauled from what was seen in the lead-up in the pages of ''Green Lantern''. They've gone from the blue uniforms shown there (modeled on Sinestro's original outfit) into the now-familiar yellow uniforms.
* CueTheSun: Dawn breaks over New York in the middle of the battle with [[HeroKiller Superboy-Prime]], [[MassOhCrap meaning that]] he no longer needs his armor and can fight the assembled heroes of Earth at full strength.
* TheDeadHaveNames: During the epilogue, Vath insists on reciting the names of every Lantern killed in action.
* DeathSeeker: Henshaw / Cyborg-Superman, who only works for the Anti-Monitor because it's promised to kill him once and for all.
** UnwantedRevival: He almost gets his wish, but is revived by his Manhunters at the very end. He cries.
* DemonicPossession: Parallax does this to Kyle, and the resulting monstrosity [[spoiler: later absorbs Hal as well. This backfires: neither of them could beat him individually, but together they fight their way out from the inside.]]
* DespairEventHorizon: Coast City was already suffering from morale problems after being destroyed in ''ComicBook/TheDeathOfSuperman'', and Sinestro intended to hit the event horizon by razing it ''again''. Averted when the people support the Green Lanterns and refuse to evacuate.
* DidYouJustPunchOutCthulhu: Hannu PUNCHES The Anti-Monitor.
* DirtyCoward: Once the amendment to allow Green Lanterns to use lethal force is effected, Amon Sur flees the battle.
* DoNotAdjustYourSet: Late in the story, Hal uses his ring to broadcast a message through every TV set and computer monitor in Coast City, warning its inhabitants to evacuate before the Sinestro Corps comes and razes the place to the ground.
* DragonWithAnAgenda: Henshaw, who just wants to die, and Superboy-Prime, who wants revenge for losing his Earth.
* EarnYourHappyEnding: Definitely one for Coast City. A city already destroyed and left basically a ghost city is viciously attacked by the Sinestro Corps and Hal begs for the citizens remaining to evacuate immediately. Instead [[IChooseToStay no-one leaves]] and after the battle is over the city has a gigantic amount of people immediately moving in and also a brand new moniker "The City Without Fear".
* EarthIsTheCenterOfTheUniverse: Technically it's not; Oa is. But played straight because of:
* TheEarthPrimeTheory: The Sinestros don't want the center of the universe, they want the center of the ''multiverse''.
* {{Foreshadowing}}: When the Guardians of the Universe decide to rewrite the Book of Oa, they tore out the "ComicBook/BlackestNight" prophecy. Ganthet and Sayd, fellow Guardians who objected to this and are thus kicked out, later explained the prophecy.
* GeniusLoci: Mogo (sentient planet), Ranx (sentient space-faring mega-city).
* GodzillaThreshold: The threat from a rival Lantern Corps is so great that the Guardians decide to revoke ThouShaltNotKill. On a smaller note, Hannu lights up his ring against the Anti-Monitor, when he usually takes personal pride in ''never'' using the thing.
* GoodOldFisticuffs: It's established that Sinestro can handle himself well in a fist fight.
-->[[spoiler:'''Ring:''' ''Warning. Power levels approaching 0.0%.'']]\\
[[spoiler:'''Sinestro (to Hal and Kyle):''' Come on, then. The ''both'' of you.]]
* HeroKiller:
** The Sinestro Corps kills hundreds of Green Lanterns throughout the storyline.
** Parallax kills Jack T. Chance on Qward, destroying his ring for good measure.
** Superboy-Prime and the Anti-Monitor. When they arrive on Earth, the entire situation takes a turn for the horrible.
* HeroicSacrifice: One of the Guardians blows himself up to destroy Superman-Prime while the other Guardians contain the blast. [[spoiler:Prime doesn't die, but he ''does'' get banished to another part of the multiverse and is out of everyone else's hair for a while.]]
* ImprobableAimingSkills: Bedovian and John Stewart. The former repeatedly scores headshots on hapless Green Lanterns from three sectors away, while the latter manages to figure out Bedovian's position and counter-snipe him.
* ITakeOffenseToThatLastOne: Amon Sur mocks Hal for being despised and abandoned by his Corps. Enter the Lost Lanterns (who hold a grudge against Hal / Parallax for leaving them for dead in space) to correct him.
--> "Despised is one thing, but abandoned? ''That'' the Green Lantern Corps don't do."
* LastDisrespects: Superboy-Prime at one point sees the grave of Bart Allen, who was killed by the Rogues at the end of ''The Flash: The Fastest Man Alive'', and proceeds to vandalize Bart's tombstone by using his heat vision to cross out the epitaph "Fastest Man Alive" and write "Stupidest Boy Dead" in its place.
* LegionOfDoom: Sinestro's Corps includes major DCU baddies Parallax, Cyborg-Superman, Superboy-Prime, and ''[[ComicBook/CrisisOnInfiniteEarths the Anti-Monitor]]''.
* LiteralDisarming: Kilowog disarms the defeated Arkillo by cutting off his ring finger.
* ManaDrain: The Manhunters have power skulls which can suck the charge out of a power ring in seconds.
* MassOhCrap: Sinestro Corpsmen realizing that the Greens are now allowed to use lethal force against them.
* MeleeATrois: The battle for Earth briefly devolves into this at the end. The Green Lantern Corps and Earth's superheroes are on one side, the Sinestro Corps are on the other side, and Superman-Prime is in the middle, fighting everyone else for the hell of it.
* MonumentalDamage: The Sinestro Corps destroy the Art/StatueOfLiberty and, somehow, replace it with a statue of their leader while they're busy invading Earth. Kyle and Guy fix it during the epilogue. Averted with the bit at Mount Rushmore, as the mountain doesn't take any damage.
* NiceJobFixingItVillain: When Superboy-Prime does away with the Anti-Monitor, [[spoiler:[[ComicBook/BlackestNight allowing Nekron to claim the body]]]].
* OhCrap: Superboy Prime thinks that the 'stupid light' inside a Guardian of the Universe is how they bleed. He screams in ''fear'' when he realizes that no, [[spoiler: it's how they die, and he's at ground-zero for the effect.]]
** Earlier Prime regains his power when the Sunlight reaches him, causing every hero to go: OH CRAP!
* OmnicidalNeutral: Superboy-Prime stops caring about sides, deciding he'd really rather just kill anything that moves. "I'll take EVERYONE! Both Corps! Bring it on!"
* OrcusOnHisThrone: Superboy-Prime sits on the Moon watching Earth for much of the Sinestro War. When he finally gets involved, he does whatever he wants including punking his own teammates. The only reason Sinestro picked Superboy-Prime as a teammate, plus two other OmnicidalManiac, at all was that he knew they'd eventually try to kill each other but not before advancing their own plans by hurting their mutual enemies.
* PreAsskickingOneLiner: Quite a few, a notable one, however...
-->'''Sodam Yat as [[SuperMode Ion]]''': Now where were we?\\
'''[[HeroKiller Superboy-Prime]]''': '''Ion''', huh? you act tough, but you don't look so special to me.
* PsychoRangers: The Sinestro Corps. A handful of Lanterns even have specific {{Evil Counterpart}}s: Arkillo for Kilowog, Ranx for Mogo, Superboy-Prime for Sodam Yat, Enkafos for Salaak, even a guy called Romat-Ru for Tomar-Tu!
* PunchedAcrossTheRoom: Most of the Franchise/{{Superman}} fights had this, with everyone being punched across cities and whatnot.
* {{Retcon}}: Just like ''Rebirth'' established Hal Jordan and Parallax as two separate beings, ''Sinestro Corps'' reveals that Ion is an entity separate from Kyle Rayner.
* SealedEvilInACan: The Anti-Monitor becomes trapped in the Black Lantern Battery.
* SealedEvilInASixPack: The fear entity Parallax is captured by the Guardians of the Universe and split into four pieces, each stored in the power batteries of the four Earth Lanterns.
* SequelHook:
** Hunter Zolomon escapes Hal's attempted interrogation in the prologue and the League is unable to give chase. Johns would pick up the hunt for Zoom over in the pages of ''Justice Society of America''.
** Before the climax, Ganthet and Sayd explain that more Lantern Corps will be emerging, and at the end they begin laying out the foundations for the Blue Corps.
** TheStinger: Another Hook: The Anti-Monitor's body is drawn to a dead planet and becomes the Black Lanterns' Power Battery. We also see black-ringed hands rising from graves, but that's just metaphorical. For now.
* ShoutOut:
** When Karu-Sil comments that Earth's beasts are weak:
--->'''Guy:''' You ever see ''"Film/{{Red Dawn|1984}}"''? ''[makes constructs of]'' '''"Wolverines!"'''
*** Also to the [[UsefulNotes/PowerFiveConferences University of Michigan]] - said wolverines are [[StealthPun wearing U of M armbands]], and Guy's got a U of M sticker on his lantern battery. Johns is also an alum of UofM, so it's a nod to his ''alma mater''.
** Plus during the fight on the US West Coast, Kilowog and Arkillo go through the San Diego Comic-Con.
** Hal refers to Lyssa Drax as the "[[Film/TheWizardOfOz Wicked Witch]]", and then uses his ring to create a house which he then drops on her.
** John calls the Anti Monitor [[Franchise/{{Ghostbusters}} Marshmallow Man]] before the Green Lantern Corps engages him.
* SpaceWhale: Ion's true form is a giant green whale.
* StartOfDarkness: In retrospect, this war was one for the Guardians. The Sinestros and other emotion-powered Lantern Corps that emerged afterward terrified them so much that they started taking more extreme steps to fight them, until they tried to [[TheEvilsOfFreeWill get rid of emotion altogether]].
* StrawNihilist: Hank Henshaw.
* TheyDiedBecauseOfYou: Kyle's life was already the trope namer for "Women in Refrigerators", but now it turns out that the disease that killed his mother at the end of his ''Ion'' ongoing was a ''sentient virus'' who joined the Sinestro Corps. Sinestro lets him know this to weaken his mental defenses against [[PuppeteerParasite Parallax]].
* ThisIsSomethingHesGotToDoHimself: During the invasion of Earth, Salaak tells other Lanterns not to get involved in Kilowog vs. Arkillo.
* ThouShaltNotKill:
** No longer enforced - rather than take it too far in the other direction, debates over proper use of this power continued being discussed within the Corps even after the war. Most Lanterns (including the human leads) make it a point to leave killing as a last resort.
** Notably, Kilowog considers an eagerness to kill to be a weakness, and defeats [[BloodKnight Arkillo]] handily while Arkillo's focusing on murdering bystanders.
** Henshaw punches Superman through the Art/StatueOfLiberty, snarling that he can't kill him. Superman calmly replies that he's never tried.
* TookALevelInBadass: Every GL still alive after the Battle of Mogo, but particularly a young Daxamite named Sodam Yat, who was a simple nobody until he was given the Ion Entity to [[SuperMode increase his powers 100 fold]] (Oh and Daxamites have [[SuperpowerLottery all the powers of Superman]]).
* VillainRespect: During the Justice League's attempt to capture Zoom in the prologue, Hunter Zolomon expresses genuine (albeit twisted) admiration for Hal and what Sinestro put him through during ''Rebirth''. He considers Hal a living exemplar of the 'lesson' he tried to put Wally West through during Johns' original ''Flash'' run: A hero who experienced great tragedy and hardship and ultimately emerged from it better and humbled.
* XanatosGambit: Sinestro set things up so that no matter what the outcome was, he would win. Either he and his troops gained control of the Multiverse, or he forced the Green Lantern Corps into adopting more aggressive tactics that he feels would be more suitable to bringing order to the Universe.
