'''Superman: New Krypton''' was a Creator/DCComics BatFamilyCrossover for the {{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 ''Brainiac'' 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 it's 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.
* ''{{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 arc ''ComicBook/SupermanGrounded'' depicts Superman dealing with the fallout.

!! New Krypton contains examples of the following tropes:

* AbusiveParents: Zod and Ursa, oh so much. Alura's not much better in her treatment of Kara.
* 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.
* BrainwashedAndCrazy: Captain Atom just can't catch a break.
* 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.
* ConservationOfNinjutsu: One Kryptonian? One of the most powerful characters in the DC Universe. 100,000 Kryptonians? So much cannon fodder.
* 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 are dead, the Kryptonians are 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.
* GeneralRipper: Zod and Lane both.
* 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.
* 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.
* 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.]]
* 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. She's nearing fifty but looks young, he's around six years old but has the body and mind of a twenty-year old.
* MugglePower: Comes in the form of Luthor and Lane and their Human Defence Corps.
* NuclearNasty: Reactron. [[spoiler:Taken UpToEleven when General Lane turns him into a living nuclear bomb powerful enough to blow New Krypton sky-high.]]
* 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.
* 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.
* 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.
