''Superman: New Krypton'' is a Creator/DCComics BatFamilyCrossover for the ''Franchise/{{Superman}}''-related titles, running from 2008 to 2010. It was written by, at various points and on various books, Creator/GeoffJohns, James Robinson, Sterling Gates, and Creator/GregRucka.

The storyline comes directly on the heels of the ''ComicBook/SupermanBrainiac'' arc, but has roots in the ''ComicBook/LastSon'' story by Geoff Johns and ''Film/{{Superman}}'' director Creator/RichardDonner.

Continuing from the end of ''Brainiac'' the story revolves around the Bottle City of Kandor becoming just the City of Kandor, having been finally unshrunk, and its 100,000 inhabitants freed from captivity. The resulting chaos and mistrust stemming from thousands of beings as strong as Superman now existing on Earth culminates in the the murder of Supergirl's father, Zor-El. His wife, Alura, believing that there is no place for her people on Earth, encases the city in a protective dome and launches it into space, using Kryptonian technology to form the planet "New Krypton" on the other side of the solar system. All Kryptonians except Superman are banned from Earth and Alura releases [[GeneralRipper General Zod]] to head up the defense of their people. On Earth, Sam Lane, the father of ComicBook/LoisLane, reappears, having previously faked his death to go underground and prepare for a day when humanity might need to oppose Superman.

From there, each title in the series goes in its own direction within the overall arc:

* ''World of New Krypton:'' Features Superman moving to New Krypton as a commander in their defense force, navigating the politics of both an interstellar cold war, as well as the rigid Kryptonian caste system.
* The main ''Superman'' book was taken over by Mon-El of ComicBook/{{Legion of Super-Heroes}} fame, freed from the PhantomZone and cured of his fatal lead poisoning, and serving as Superman's replacement, both on the Justice League and as the protector of Metropolis.
* ''Action Comics'' was headlined by newcomers Nightwing and Flamebird, two Kryptonians hiding on Earth to track down and imprison escaped criminals from the Phantom Zone.
* ''Adventure Comics'' got involved in mid-arc and showed how the other members of the Legion of Super-Heroes plus the Conner Kent Superboy handled the conflict.
* ''Comicbook/{{Supergirl}}'' dealt with the continuing fallout of Zor-El's assassination, with Kara trying to apprehend his killer, Reactron, while being both a literal illegal alien, and a HeroWithBadPublicity.
* ''Codename: Patriot'': A crossover within the crossover, revolving around the attempted assassination of General Zod.
* ''Last Stand of New Krypton:'' Brainiac makes one last attempt to reclaim Kandor, with Zod, ComicBook/LexLuthor, and the Legion of Superheroes all pursuing their own agendas in the chaos.
* ''War of the Supermen:'' The end of the road for New Krypton, with Lane and Luthor initiating their endgame, and Zod's forces vowing to wipe out the Earth. Ends with the ResetButton thoroughly pressed, and the status quo almost entirely restored.

The story arcs ''ComicBook/SupermanGrounded'' and ''[[ComicBook/{{Bizarrogirl}} Supergirl: Bizarrogirl]]'' depict Superman and Supergirl dealing with the fallout.

!! New Krypton contains examples of the following tropes:

* AbusiveParents: Zod and Ursa to Christopher, oh so much. Zod refers to him as a disappointment he's willing to replace in the future and Ursa refers to him as disgusting weak mewling mutation. Alura's not much better in her treatment of Kara in terms of emotional abuse after her husband's death to the point that Kara actually wished Alura had died first instead of her father.
* ActuallyADoombot: [[spoiler: Lex Luthor]] gets killed in the end?!?! Oh, wait, no... just a decoy robot he planted on Brainiac's [[spoiler: ship from the start]] to have some maneouvring space without being bothered by the other multiple fighting parties.
* ANaziByAnyOtherName: General Lane and General Zod.
* {{Archenemy}}: This arc firmly established Reactron as Supergirl's. It's also the first story to see Superman's three most deadly enemies--Luthor, Brainiac, and Zod--active at the same time, and in direct competition with one another.
* AteHisGun: General Lane. Because, as we all know, it's always...
** BetterToDieThanBeKilled: "I said no prisoners, Lois. And I meant it."
* TheBadGuyWins: Lane and Luthor achieve their goal of wiping out the Kryptonians, and Luthor regains control of his company in the process.
* BigBadEnsemble: Zod and Lane are EvilVersusEvil, while [[ComicBook/LexLuthor Luthor]], ComicBook/{{Brainiac}} and Jax-Ur have their own agendas.
* BookEnds: In the first issue, ComicBook/LoisLane is placing flowers at her father's grave as her sister Lucy reminds her angrily that Sam Lane never liked flowers. At the final issue, Lois visits her father's grave again. When asked why she didn't bring flowers she replies her father didn't like them and doesn't deserve them.
* BrainwashedAndCrazy: Captain Atom just can't catch a break.
* BulletCatch: In the ''World of New Krypton'' mini, Supergirl catches a sniper's bullet before the projectile hits its intended victim.
* CainAndAbel: Lois the Abel and Lucy/Superwoman is the Cain.
* CallingTheOldManOut:
** After an entire story arc's worth of emotional abuse, Kara finally calls her mother on her bullshit in the beginning of ''War of the Supermen''. Unfortunately, Reactron uses the opportunity to detonate himself in an explsion that blows New Krypton sky-high and Alura uses her final moments to save her daughter.
** Chris Kent's actions against Zod and Ursa can qualify this as well.
** Lois opposes both her father and her sister in their plans of genocide. By the end of ''New Krypton'', she hardly acknowledges them as family.
* ChekhovsGun: The False Rao.
* ColdBloodedTorture: Supergirl captures her father's murderer Reactron and takes him to her planet so he stands trial. However Allura gets him tortured for information, making her daughter, who wanted justice rather revenge, furious when she finds out.
* ConflictKiller: Brainiac. When he enters the scene, everyone has to put aside their agendas and team up to stop him, including Superman, Zod, Luthor, Lane, Supergirl, the Legion, and all the Kryptonians. Once he's finally beaten, things go downhill fast for the ad hoc alliance.
* ConservationOfNinjutsu: Played straight or averted depending on the issue. When Doomsday shows up, Superman, Supergirl and a dozen of Kryptonians beat him into the ground. Later, Reactron and Metallo sneak into Kandor and kill dozens of Kryptonians by themselves, while Brainiac kills over 11,000 of them with his ship and robots within minutes of beginning his attack. And in the ''War of Supermen'' arc 80,000 Kryptonians are cannon fodder. Perhaps justified because the powers are very new to the population and only a small amount such as Zod are accustomed to using them to a degree they would be considered on the same level as Superman.
* CryIntoChest: When [[spoiler:New Krypton gets destroyed]] during the "War of the Supermen", making [[spoiler:Superman and Supergirl the last of their kind once again]], Supergirl cries into her cousin's chest at least twice.
* DeathEqualsRedemption: When Reactron detonates himself, Alura uses what little time she has to put her daughter into safe zone. It's clear she loved her daughter, even if she picked the worst possible moment to prove it.
* DemonicPossession: [[FallenAngel Vohc the Breaker]] has possessed the Kryptonian criminal Jax-Ur.
* DownerEnding: Spectacularly so. Millions of people are dead, the Kryptonians are nearly extinct again, and Luthor is not only a greater KarmaHoudini than ever, but General Lane is regarded as a hero.
* TheDragon: Ursa to Zod, Superwoman to General Lane, and ComicBook/CaptainAtom to Mirabai.
* DragonInChief: Luthor is ostensibly working for Lane, but not only [[DragonWithAnAgenda has an agenda]], but is completely indispensable to Lane's operation. Remove Luthor, and the whole edifice comes crashing down.
* EarthShatteringKaboom: On New Krypton, courtesy of Lex Luthor and Reactron.
* EvilGenius: Luthor, Brainiac, and Dr. Calomar.
* EvilVersusEvil: General Zod, a ruthless, xenophobic GeneralRipper, has as his opposite number on Earth... General Sam Lane, a ruthless, xenophobic GeneralRipper.
* EvilerThanThou: Zod, Lane, Luthor, and Brainiac are all in competition for the title of biggest son-of-a-bitch in this story.
* FinalSolution: Generals Zod and Lane are both hellbent on annihilating one another's races. Lane, with a lot of help from Luthor, ends up achieving his goal; while he doesn't kill ''every'' Kryptonian, there aren't enough left to reestablish a breeding population.
* GambitPileup: Alura orders her daughter to capture Reactron and bring him back to New Krypton. When Kara drags him along to the planet, a mob tries to lynch him and Alura takes advantage of the ensuing chaos to fake his death, throw him in a cell and make him talk... [[spoiler: which was a bad idea because Luthor and Lane's gambit involved transforming Reactron into a living bomb and setting him off inside of New Krypton]].
* GeneralRipper: Zod and Lane both.
* GenesisEffect: Kryptonian scientists use Brainiac's technology to lift a newly enlarged [[CityInABottle Kandor]] into space and grow a planet underneath it. The ''Who Is Superwoman?'' story arc reveals, though, they don't appear to be able to terraform it.
* GodSaveUsFromTheQueen: Mirabai the Forlorn, the ruler of Sorcerer's World.
* GoodRunningEvil: Superman's main motive for joining New Krypton is to improve its culture (and keep an eye on Zod) from within. When he refuses to pick a Guild, he's placed in the Military Guild under Zod's leadership, but doesn't let that stop him from thinking outside the box, such as defusing hostage situations without bloodshed. When Zod's incapacitated by an assassin, Kal briefly becomes ''General'' Kal-El.
* GraveMarkingScene: Happens several times. At the beginning, Clark Kent and his mother visit Jonathan Kent's grave and Lois visits her father's (and has an argument with her sister Lucy). At the end of the story, Supergirl builds a grave for all Kryptonians who perished during the War and Lois visits her father's grave for the last time.
* GottaCatchEmAll: The Phantom Zone escapees in ''Action.''
* IfYouKillHimYouWillBeJustLikeHim: Lois convinces Supergirl not to kill her father with this argument.
* HateSink: Commander Fer-Gor of the Kryptonian army. At least Zod has the excuse of wanting to protect his people from the human hostilities, but Gor is a smug, sadistic bully who enjoys hurting people weaker than him, be they human or Kryptonian. [[spoiler:Readers can only cheer when Luthor kills him.]]
* HeroWithBadPublicity: Supergirl, right from the start, thanks to Cat Grant. Superman joins her not long after due to fallout from the Kryptonians' actions. Nightwing and Flamebird become this when Project 7734 frames them and Supergirl for murdering Mon-El and destroying the Metropolis water supply.
* IllGirl: Lana Lang.
* InsigniaRipOffRitual:
** In Supergirl (Volume 5) 5 #41, Supergirl rips the "S"-shield off Superwoman's clothes screaming she is a murderer who doesn't deserve to wear her family's crest.
--->'''Supergirl:''' You're asking for mercy? Like Agent Liberty got?! Like poor Mister Henderson!? Like my father!? You don't deserve mercy, you deserve a beating! And this? You don't deserve to wear this.
** In ''World of New Krypton'' #12, General Zod is so angry when he finds out that Commander Gor disobeyed his direct orders and gunned a fugitive down than rips his commander insignia off his chest and demotes him right away.
* KarmaHoudini: Luthor. Zod's back in the Phantom Zone. Reactron and Lane are dead. Metallo's in jail. Brainiac loses his ship and much of his accumulated knowledge. But Luthor? Luthor is rewarded for his role in the genocide, by having his company returned to him.
* KickTheSonOfABitch: Face it, you cheered when [[spoiler:Luthor killed Gor.]]
* KilledOffForReal: [[spoiler:Mr. Kent, Zor-El, Alura, and Reactron are all major players who die and were never brought back before the reboot. All Kryptonians not sent into the Phantom Zone or allied with Superman are also shown as dead.]]
* KnifeNut: Ursa, who uses a kryptonite knife, even though it makes her sick just holding it.
* [[WomanScorned Man Scorned]]: Vohc is a godly example. He was in love with Flamebird, but since her entire purpose in life was to wreck his stuff, it didn't turn out well.
* MayDecemberRomance: Thara and Chris. Thara's nearing fifty but looks young due to her time trapped by Brainiac. Chris is around six years old but has the body and mind of a young adult due to the Phantom Zone tampering with his genetics to make him age years more than he should and Zod's machines that accelerating and developing his mind. It becomes a Squick situation when it's revealed Thara actually fell in love with a six year old boy Chris in the midst of a mind meld they experienced.
* MugglePower: Comes in the form of Luthor and Lane and their Human Defence Corps.
* NeckLift: Supergirl does this to [[spoiler:Sam Lane]] after he has [[spoiler:successfully engineered the death of New Krypton and the Kryptonian genocide]].
* NuclearNasty: Reactron. [[spoiler:Taken UpToEleven when General Lane turns him into a living nuclear bomb powerful enough to blow New Krypton sky-high.]]
* OffscreenMomentOfAwesome: In the final arc "War of the Supermen", ComicBook/{{Supergirl}} defeats her old enemy Superwoman for good. It's a brutal, one-sided beatdown... which happens completely off panel.
* OlderThanTheyLook: All of the Kandorians and PhantomZone escapees. Thara Ak-Var, for instance, looks maybe twenty, and hasn't actually aged more than a couple of years, despite spending three decades active and awake in the bottle city. This is {{Handwave}}d as being a result of Brainiac's technology.
* OurHeroIsDead: When Mon-El, the only hero in the story that's actually liked by the masses, is "killed" by Lane's agents.
* PersonOfMassDestruction: Luthor and Lane's gambit involves transforming NuclearNasty Reactron into a living bomb and setting him off inside of New Krypton.
* PresidentEvil: Alura after she takes leadership of New Krypton.
* PsychoForHire: Pretty much the entirety of Project 7734, but Codename: Assassin and Reactron are the standout examples.
* RedHerring: [[spoiler: When Nightwing and Flamebird first appeared, much was made of Nightwing's tactile telekenesis and Flamebird's fire powers, in order to lead readers to believe they were the currently-dead Conner Kent and the somewhere-in-limbo Linda Danvers. They weren't, although Conner did join the storyline, having been resurrected in ''Legion of Three Worlds''.]]
* ReverseMole: Natasha Irons, inside 7734.
* SecretIdentity: Mon-El, who tries to blend in by posing as Science Police officer Jonathan Kent.
* SomeoneToRememberHimBy: Billie Harper reveals to the Guardian that she's pregnant with Mon-El's child.
* StatusQuoIsGod: Let's face it, Superman no longer being nearly the LastOfHisKind was never going to last.
* StrangerInAFamiliarLand: It happens to Supergirl when she moves to New Krypton and finds she's been living in Earth for so long that Kryptonians are "alien" to her now.
-->'''ComicBook/LanaLang:''' So what's it like over there?\\
'''Supergirl:''' On New Krypton? It's... different. Our people are happy there. The planet itself is beautiful, too, but... It's weird, but being around other Kryptonians like my mother, I'm really starting to feel... well...\\
'''Lana:''' Alien?\\
'''Supergirl:''' Some of them are so different from humans, Lana. They think differently, they speak differently, they... react differently. I've been on Earth so long, it's been hard for me to fall back into being "just another Kryptonian".
* TemptingFate: Zor-El tempted fate several times:
** In "Superman: New Krypton Special", Zor says now they have powers "We'll never be in harm's way again". [[spoiler:he got murdered shortly after. And New Krypton got blown up]].
** In ''Supergirl vol.5 #34'' Kara questions the wisdom of having a Brainiac's robot keeping Argo's shields up, and asks what would happen if it woke up. Her father reiterates over and again it can't and won't turn itself back on. Despite everything, the robot woke up and nearly killed them.
* TakingTheBullet: Krypto intercepting a kryptonite knife intended for Superboy.
* UndercoverCopReveal: Different members of the Legion Espionage Squad, at various points. Chameleon Boy was actually undercover ''as'' a cop.
* UnderestimatingBadassery:
** Reactron brought golden kryptonite (which nullifies the powers of a Kryptonian) to the fight, thinking he'd kill Supergirl easily. It turns out that Supergirl has been trained by both Batman and Wonder Woman and knows Klurkor (a Kryptonian martial art).
** General Sam Lane has the habit of declaring that his daughter Lucy Lane -a. k. a. Superwoman- is a soldier who will not be bested by a "teenage hussy" two minutes before Supergirl mops the floor with Superwoman.
* WillingChanneler: [[OurAngelsAreDifferent Nightwing and Flamebird]], two minor Kryptonian deities, choose Chris Kent and Thara Ak-Var as their respective hosts.
* XanatosSpeedChess: Between General Zod and General Lane, the latter receiving a lot of assistance from ComicBook/LexLuthor. Brainiac and Brainiac 5 get in on the game as well, partway through.
* YouKilledMyFather: The Guardian says this verbatim to Codename: Assassin.
* YoungerThanTheyLook: Chris Kent goes from looking his age (about six) to looking around 12, to his mid teens, early twenties, and eventually old age, due to being a mutant.
