History Main / HostileTerraforming

** In the ''WesternAnimation/TheTransformers'', episode "The Key to Vector Sigma", Megatron finds out the titular key has the ability to turn the planet Earth into the metal, but fortunately, the damage is limited to a few poor trees.

** This idea was used earlier, in the ''WesternAnimation/TheTransformers'', episode "The Key to Vector Sigma."

* ''Film/TheyLive''. One of the members of the Resistance says in a TV broadcast that the alien infiltrators have caused the release of certain gasses (such as flourocarbons and methane) in order to make the Earth's atmosphere more like that of their home planet ("turning our world into theirs"). Since the aliens are capable of surviving on Earth even with its current atmosphere, it clearly isn't necessary for them to live here, so it's probably just to make them feel more comfortable.
* In ''Film/TheTrollenbergTerror'', a mysterious [[FogOfDoom fog]] on the side of a Swiss mountain turns out to be the result of alien invaders, trying to create more hospitable conditions for a large-scale invasion.

* ''Literature/TheWarOfTheWorlds'': Possibly an UrExample. Martians use areoforming as a weapon, introducing "[[AlienKudzu red weed]]" that chokes out all other plants and sucks up Earth's water. [[spoiler: Fortunately it's as susceptible to Earth microbes as the other Martians]].

* This is the purpose of the Mimics in ''LightNovel/AllYouNeedIsKill'', though in fairness they don't know the Earth has intelligent life.

** ''Series/StarTrekDeepSpaceNine'': Sisko used a specialized warhead to poison the atmosphere in such a manner that it would be uninhabitable for human life, but functional for Cardassian in an attempt to force Eddington to surrender. Though the Maquis did pretty much the same thing (except rendering it uninhabitable to Cardassian life but safe to human) to multiple Cardassian colonies.

** In "Corner of the Eye", the aliens plan to destroy Earth's atmosphere to make the planet habitable for them.
** In "Birthright", the alien infiltrators' long-term plan is to use a chemical to terraform Earth over the course of 30 years by giving it a methane atmosphere which they can breathe. Of course, this would result in humans being wiped out. The aliens claim that said chemical, BE-85, is a fuel additive designed to clean up the atmosphere, meaning their plot entails tricking humanity into releasing the chemical themselves on a global scale.
** In "To Tell the Truth", the native population of Janus Five view the human colonists' terraforming of their planet as such.
** In "Manifest Destiny", the UFS ''Rhesos'' wiped out the indigenous population of Trion, millions of beings at an early stage of evolutionary development, using neutron bombs in order to terraform and eventually colonize the planet.
* In ''Series/QuatermassII'' an alien vanguard takes over selected humans so they can build a chemical plant to make an atmosphere that will support their kind of life, and kill off all terrestrial life.

* Creator/BrianWAldiss' ''The Saliva Tree'' has a pair of aliens landing near a farm somewhere in England and spreading a chemical that greatly increases crop yield and starts changing the local animal life, including humans, to better suit the invaders' tastes. It starts when everyone at the market complains of the milk being spoiled, and the farmhand who's selling it tastes it as perfectly fine. The main character barely has time to take his lady friend (later fianceé) before the mutagenic effects of the chemical become irreversible (as is, she spends some time violently ill as her body struggles to resist the chemical). The others who stayed were not so lucky.

* In ''The Taking'', a 2004 novel by Creator/DeanKoontz, characters speculate that this may be the goal of whatever has arrived with the storm that sweeps across the West Coast. [[spoiler:After the discovery that the aliens are in fact demons that have (possibly) come into the Universe through a black hole, it becomes clear that their intention was to reverse terraform the world into a literal HellOnEarth]].

* Creator/IsaacAsimov's ''Literature/InAGoodCause...'' has information on the sulphur-reducing Diaboli terraforming the obscure human colony of Chu Hsi to be fit for Diaboli life falling into the hands of a group of human anti-Diaboli Federalists, who intend to release it to break up a Diaboli-sponsored all-human conference. Subverted: [[spoiler: Except it turns out the information was a forgery by Earth's government, as part of a long-running scheme to manipulate things so that when the human-Diaboli war comes, no human power is on the Diaboli's side.]] Then ''double''-subverted: [[spoiler: Earth's government had found out the Diaboli eventually planned to terraform human-populated worlds, but they weren't going to do it ''yet'']].

* Creator/IsaacAsimov's ''In A Good Cause...'' has information on the sulphur-reducing Diaboli terraforming the obscure human colony of Chu Hsi to be fit for Diaboli life falling into the hands of a group of human anti-Diaboli Federalists, who intend to release it to break up a Diaboli-sponsored all-human conference. Subverted: [[spoiler: Except it turns out the information was a forgery by Earth's government, as part of a long-running scheme to manipulate things so that when the human-Diaboli war comes, no human power is on the Diaboli's side.]] Then ''double''-subverted: [[spoiler: Earth's government had found out the Diaboli eventually planned to terraform human-populated worlds, but they weren't going to do it ''yet'']].
* In ''The Keys to December'' by Creator/RogerZelazny the homeless protagonists are cooling down a planet too hot for them. This forces the local humanoids to evolve civilization on par with Ice Age humans. The main point of the story is the Catforms' dilemma, if they should doom the intelligent natives. There are multiple hints that Ice Ages on Earth may have been a similar terraforming project, which somehow was reverted.

* The Alectors of the ''Corean Chronicles'' carried this out against the Ancients when they began colonizing Corus.
* In the ColdWar thriller ''A Cage of Ice'' by Duncan Kyle, the Soviet Union is using aircraft to spray black powder on the Arctic icecap to increase its absorbing of sunlight and melt the polar icecaps, with the aim of creating an ice-free Northern port as well as flooding coastal cities in the West. The novel is HarsherInHindsight, as Western politicians might be more willing to take measures to combat GlobalWarming if it was a DirtyCommunist plot!

* ''WesternAnimation/StormHawks'': The Blizzarians' {{Terraform}}ing of a desert terra (converting it into an arctic tundra) in "Fire and Ice" counts two ways. In a somewhat heroic twist on the trope, the desert terra was actually, unbeknownst to them, Repton's personal leisure retreat and the Raptors are irate at the new climate. But on the downside, the Blizzarians didn't bother to properly check there weren't any heat-adapted animals living on the terra (which there are) before they froze it over.

* Franchise/MonsterVerse: This trope is generally theorized by Monarch to be the motivations of most of the hostile Titans -- the [=MUTOs=] and MUTO Prime, Ghidorah, Camazotz -- respectively. Forcibly and rapidly reshape the region or the entire planet to suit themselves, in a way which kills off the pre-existing ecosystems. For examples, King Ghidorah's process involves spreading {{Perpetual Storm}}s worldwide with his WeatherManipulation whilst forcing the other Titans to create a NaturalDisasterCascade, and Camazotz's process involves permanently enveloping Skull Island in an endless destructive superstorm to block out the daylight. This draws an interesting parallel between the antagonistic Titans and the human race (who, as described under the Real Life folder, are themselves doing this to the Earth), especially when one considers that Godzilla and Kong who do battle with these Hostile Terraforming Titans are guardians or straight-up embodiments of nature's ability to strike its own balance respectively.

** Megatron's ultimate plan in ''VideoGame/TransformersDevastation'' is to turn Earth into a second Cybertron. [[spoiler: However, the technology he uses comes from Optimus's assumed heroic predecessor.]]

* The ''VideoGame/CommandAndConquerTiberianSeries'' centres around humanity adjustments to a world being transformed by the eponymous ToxicPhlebotinum, which not only converts the atmosphere and the ecosystem, but also extracts useful minerals from the Earth's crust for easy harvesting when the invaders finally arrive in person.

* ''VideoGame/HalfLife2'' in its released form contains hints of this - most notably, the Combine drain the Earth's oceans and use Xen species such as Headcrabs and Leeches as biological weapons. The original beta however went much further - a key location in the game was the "[[http://half-life.wikia.com/wiki/Air_Exchange Air Exchange]]", which replaced the air with noxious gases breathable by the Combine, and which meant that all human characters in the game had to wear gas masks.

* In ''VideoGame/{{Spore}}'', you can deterraform planets of an enemy empire to reduce the level of colony that planet can maintain (especially effective against enemy home-worlds, as it reduces them from thriving T-3s with extra settlements, to a basic T-2 with two settlements at best). Empires will regard this as an act of war. More in line with this trope, the Grox, EnemyToAllLivingThings, can be killed by terraforming their planets, and likewise they specialize in deterraforming.

* ''VideoGame/TransformersDevastation'': Megatron's EvilPlan is to use the Plasma Core Generator on the Proudstar, an ancient Cybertronian ship, to terraform Earth into a new Cybertron (which will naturally have lethal consequences for all life on Earth). Megatron believes that [[EvilCannotComprehendGood Optimus Prime will balk at destroying the Proudstar]] because it's a repository for ancient Cybertronian knowledge that were lost long ago due to Cybertron's war.

A specific context for {{Terraform}}ing, and if it's Earth or an Earth-like world being changed to another ecosphere, the term would be "xenoforming". Often overlaps with AtmosphereAbuse, though the latter doesn't have to occur specifically for terraforming purposes. Depending on methodology, it can involve GreyGoo, GaiasVengeance, TheNightThatNeverEnds, AlienKudzu, or MeatMoss. Due to the destruction, this is an ApocalypseHow of the Planetary Species or Total Extinction variety, depending on how much of the planet's multicellular life is replaced.

[[folder:Multiple Media]]
* ''Franchise/DoctorWho'':
** The Ice Warriors do this a couple times. In [[Recap/DoctorWhoS6E5TheSeedsOfDeath "The Seeds of Death"]], they attempt to xenoform Earth using a fungus that will extract oxygen from the atmosphere. The novel "[[Literature/EighthDoctorAdventures The Resurrection of Mars]]" shows them successfully Hostile Terraforming another planet, making it hostile to both humans and its once-abundant native life within a year.
** And from [[HumansAreTheRealMonsters the other direction]], [[Recap/DoctorWhoS9E4TheMutants "The Mutants"]] has a group of evil human colonists plotting to terraform an inhabited planet in a way that will genocide the indigenous sentient culture.
** [[Recap/DoctorWhoS30E2TheFiresOfPompeii "The Fires of Pompeii"]]: It's briefly indicated that the [[LivingLava Pyroviles]] would've done this to Earth once they started merging with and converting with millions of humans for their AlienInvasion. Lucius shoots down the Doctor's pointer that the planet they're trying to invade is 70% water by stating water can boil.
** [[Recap/DoctorWhoS30E4TheSontaranStratagem "The Sontaran Stratagem"]]/[[Recap/DoctorWhoS30E5ThePoisonSky "The Poison Sky"]]: Weakened by their eternal war with another race of ScaryDogmaticAliens, the Sontarans hatch an uncharacteristically circuitous plan to bathe the Earth in gas which is poisonous to native life but nutritious to themselves, so that they can turn the Earth into a clone world for themselves on which to mass-spawn more soldiers.
** In the audio story "The Runaway Train", an aquatic alien race to whom oxygen is poisonous sent a terraforming device to Earth which would've turned it into a [[SingleBiomePlanet water world]] so they could use it as an outpost.
** ''Literature/DoctorWhoNewAdventures'': In the AlternateUniverse in "Blood Heat" where the Silurians are retaking the Earth from humanity, they've been reverting Earth to a similar prehistoric state as it was in when they originally ruled it. They've brought back extinct plants and animals which now coexist alongside their modern counterparts in new ecosystems, mutated fruit which is inedible to humans grows now, they're heating up certain parts of the planet, and they're converting deserts into rainforests. Unusually for this trope, the Silurians aren't introducing an alien ecosystem to Earth but rather are reverting the landscape partly to what it was like in prehistoric times, although the conditions are still very much hostile to humans.

* Franchise/MonsterVerse: This trope is generally theorized by Monarch to be the motivations of most of the hostile Titans -- the [=MUTOs=] and MUTO Prime, Ghidorah, Camazotz -- respectively. Forcibly and rapidly reshape the region or the entire planet to suit themselves, in a way which kills off the pre-existing ecosystems. For examples, King Ghidorah's process involves spreading {{Perpetual Storm}}s worldwide with his WeatherManipulation whilst forcing the other Titans to create a NaturalDisasterCascade, and Camazotz's process involves permanently enveloping Skull Island in an endless destructive superstorm to block out the daylight.

* ''Franchise/StarTrek'':
** ''Series/StarTrekDeepSpaceNine'': Sisko used a specialized warhead to poison the atmosphere in such a manner that it would be uninhabitable for human life, but functional for Cardassian in an attempt to force Eddington to surrender. Though the Maquis did pretty much the same thing (except rendering it uninhabitable to Cardassian life but safe to human) to multiple Cardassian colonies.
** The ''Series/StarTrekTheNextGeneration'' episode [[Recap/StarTrekTheNextGenerationS1E17HomeSoil "Home Soil"]] featured a Federation terraforming project that was doing this by accident. And the locals didn't like the "Ugly Bags of Mostly Water" mucking up their planet.
** In ''Literature/StarTrekTheGenesisWave'', the titular Wave is designed to do this, transforming planets into new homes for PlantAliens the Lomarians. Fired from the Lomarians' hidden base, the energy wave transforms worlds in its path into swampy hellholes through use of Genesis technology stolen from Dr. Carol Marcus. The Lomarians even go as far as to program their own genetic profile into the genesis matrix, combining colonization with reproduction by having new Lomarians spontaneously generated on transformed worlds.
* ''Franchise/StarWarsLegends'': The Yuuzhan Vong in the ''Literature/NewJediOrder'' use OrganicTechnology exclusively and "Vongform" many of the planets they conquer, including Coruscant. In the ''ComicBook/{{Legacy}}'' comics a century later the Jedi and Vong shapers attempt to use their technology to re-terraform several devastated planets in the galaxy, but the Sith sabotage the effort.
* ''Franchise/{{Transformers}}'': This crops up quite a few times with the Decepticons and/or other hostile Transformers planning to remake organic worlds such as Earth into mechanical replicas of Cybertron.
** This idea was used earlier, in the ''WesternAnimation/TheTransformers'', episode "The Key to Vector Sigma."
** In ''ComicBook/TransformersGeneration2'', the Cybertronian Empire's modus operandi was to kill all the inhabitants of each planet and then mechaform the planet itself to make replicas of Cybertron.
** ''ComicBook/TransformersTwilightsLastGleaming'': With control of the Allspark, Megatron's EvilPlan at the series' start is to use it to transform Earth into a new Cybertron. Although he's killed and the Allspark destroyed before he can complete the plan, the humans and Autobots were too late to stop the Allspark's influence poisoning the Earth to its core, threatening to destroy the planet anyway.
** ''WesternAnimation/TransformersPrime'': Specifically Hostile Cyberforming. The Decepticons twice attempt to use the Omega Lock's [[{{Terraform}} cyberforming]] beam to instead convert Earth into a Cybertron-like world, which threatens to eradicate all organic life on the planet in the process. The same technology could be used for simply restoring Cybertron to its former glory, but Megatron uses it to attack Earth out of megalomania.
** On a smaller scale, Decepticon pirate, Hammerstrike of ''WesternAnimation/TransformersRobotsInDisguise2015'' causes oil spills to try to recreate the Cybertronian seas that he's accustomed to.
** Megatron's ultimate plan in ''VideoGame/TransformersDevastation'' is to turn Earth into a second Cybertron. [[spoiler: However, the technology he uses comes from Optimus's assumed heroic predecessor.]]

* ''Franchise/CthulhuMythos'': Allies of the Great Old Ones and Outer Gods are occasionally found trying to work towards "clearing off the Earth" for their masters. This was Wilbur Whateley's goal in ''Literature/TheDunwichHorror'', for instance.

* ''Literature/LastAndFirstMen'', the Fifth Men escape a dying earth by terraforming Venus. Halfway through the process they discover that Venus is inhabited and oxygen is lethal to the natives, they keep at it anyways.

* The ultimate plan of the alien conquerors in John Christopher's ''[[Literature/TheTripods Tripod]]'' novels is to convert Earth's atmosphere into something they can breathe.

* In ''Literature/TheWarOfTheWorlds'', Martians use areoforming as a weapon, introducing "[[AlienKudzu red weed]]" that chokes out all other plants and sucks up the planet's water. [[spoiler: Fortunately it's as susceptible to Earth microbes as the other Martians]] Possibly an UrExample.

* The ''Series/{{Andromeda}}'' episode "Point of the Spear", the Pyreans (aliens that live in Venus-like environments) tried to forcibly pyroform a Commonwealth world. A large battle breaks out, and to prove that the Commonwealth is not one to be messed with, Dylan orders the planet's destruction via [[EarthShatteringKaboom Nova Bomb]].

** [[TheCorruption Chaos energy]], which is spread into the Materium from [[HyperspaceIsAScaryPlace the Warp]] through [[NegativeSpaceWedgie Warp rifts]], is the pure destructive kind. Ground tainted by Chaos can be distinguished through its deadened or charred appearance, the [[BodyHorror horrifically mishapen people, animal and plantlife]] caused by spreading through contact, and the crazy effects on the sky. Standing on such ground and not going crazy requires considerable mental fortitude.
** "Tyrantforming" is the first stage of devouring a planet by the Tyranids - the spores dropped onto the surface merge with local plantlife, turning it into HungryJungle - rapidly draining the ground of all nutrients. The Tyranids then devour the plants. By the time they're finished with a planet the lack of a breathable atmosphere and any oceans makes the planet inhospitable without substantial effort, while Tyranid organisms left behind make that prospect extremely unwise.
** Orks are described as "an invasive ecosystem by themselves", and shed spores to generate new creatures, which will grow to be squigs, grots, gretchen or full orks depending on the conditions. With enough orks, they create their own flora and fauna, and the whole ecosystem is "orkoformed".

* ''WesternAnimation/TransformersPrime'': The Omega Lock in Season 2 is capable of producing pure "cybermatter" to rapidly transform planets into environments similar to [[MechanicalEcosystem Cybertron]]. The Autobots and Decepticons both pursue it the hopes of restoring Cybertron to its former glory, but the victorious Megatron announces that he intends to use it on the Earth as well, which would destroy all existing life upon it. Optimus Prime [[ShootTheDog makes the hard decision to destroy the Omega Lock]], but [[spoiler:it still functions long enough to provide Megatron with a massive, technologically-advanced fortress on Earth, dubbed "New Kaon"]]. [[spoiler:Towards the end of Season 3, the Decepticons rebuild the Omega Lock and attach it to the ''Nemesis'', producing their own raw cybermatter with the aid of Ratchet's synthetic energon formula, and attempt once again to xenoform the Earth.]]

* ComicBook/TheAuthority battles God ("The Outer Dark," issues 9-12). Earth's creator is a moon-sized alien being that created the planet as a retirement home. Since Earth's creation, changes to its orbit and ecosystem led to the rise of life as we know it, instead of somewhere its creator would be comfortable. God immediately sets about "fixing" that. Or as The Engineer calls it, "turdscaping".

* In the ColdWar thriller ''A Cage of Ice'' by Duncan Kyle, the Soviet Union is using aircraft to spray black powder on the Arctic icecap to increase its absorbing of sunlight and melt the polar icecaps, with the aim of creating an ice-free Northern port as well as flooding coastal cities in the West. The plot is HarsherInHindsight, as Western politicians might be more willing to take measures to combat GlobalWarming if it was a DirtyCommunist plot!

* A minor example in Creator/HarryTurtledove's ''[[Literature/{{Worldwar}} Colonization]]'' books: when the [[LizardFolk Race]]'s Colonization fleet finally arrives, they bring with them plants and animals from Home, a [[SingleBiomePlanet desert world]]. The plant life thrives in Earth's desert regions and spreads faster than weeds. Since the Race also happens to control most of Earth's desert regions, this works out for them. However, arid American states are also being taken over by the [[AlienKudzu alien plants]]. Home's animals are even worse. Since they're used to food being scarce, they eat all plants down to the roots, leaving not a blade of grass in their wake. Many characters compare them to goats, only much worse. When the US complains to the Race about their animals crossing into American territory, Fleetlord Atvar simply tells them they're free to destroy any plants and animals in their own territory as they wish. Of course, while a farmer with a rifle may scare off and shoot a coyote, good luck doing that to a brontosaurus or a whole herd of them. Neither the plants nor the animals are likely to move into the colder regions, though.

* ''The Genocides'' by Thomas M Disch has aliens reconfigure Earth for cultivation, with the subsequent destruction of humanity being more along the lines of pest control.

** The 2012 reboot, ''Anime/SpaceBattleshipYamato2199'', puts more focus on this aspect of the Gamilas attacks on earth, describing the effects as "pollution" instead of explicit radiation like the original series and live-action movie. The Planet Bombs also seeded poisonous AlienKudzu that's shown penetrating the underground cities, [[spoiler:which is discovered as identical to the plant life on the Floating Continent. However, that ecosystem is not suitable for Gamilan life in this version; the Hostile Terraforming is strictly a way to SaltTheEarth]]. This was {{RetCon}}ned, however, in ''Anime/SpaceBattleshipYamato2202'', where it's shown the Gamilas attacks on Earth were meant to be transforming Earth into a state more habitable to the Gamilons all along.

* ''Young Samson & Goliath'' episode "Cold Wind From Venus". Two robots from Venus plan to impose "environmental control" over the entire Earth by reducing the temperature to -200 degrees Fahrenheit (turning it into an [[SingleBiomePlanet Ice Planet]]) so Venusians can settle here.

* ''Literature/TheWarAgainstTheChtorr'' features an invasion by an alien ecosystem, almost all of it deadly to man.

* ''Anime/GodzillaPlanetOfTheMonsters'': Godzilla has inflicted this on the Earth's biosphere in the 20,000 years since humanity's HomeworldEvacuation; making the planet a DeathWorld for humans with unbreathable air and with extensions of Godzilla in place of plant life which are hard enough to break knives, which release metallic pollen that interferes with radio communication, and can produce Flying-type Servum monsters. Interestingly for this trope, it's suggested the Hostile Terraforming is [[GaiasVengeance the work of Mother Nature herself purging the planet of humanity's ecologically-destructive ways]] rather than the work of an invasive species.

** This is the ultimate goal of HADES. [[spoiler:Specifically, he was designed as a subroutine for GAIA, the AI responsible for terraforming the planet back to habitability after Zero Day. Building an ecosystem is complicated, but if she got something wrong, she was too much of an AllLovingHero to do what needed to be done. HADES was designed to take control away from her if necessary, use the terraforming system to reset everything back to zero, and then give control back to her so she could start again. Unfortunately, nineteen years before the start of the game, a foreign signal of unknown origin caused HADES to activate unnecessarily. GAIA sacrificed herself to destroy him (while also creating a way to have herself rebooted eventually), but he managed to upload into a damaged Titan and continue his work to destroy everything. Worse, if he succeeds, GAIA won't be around to re-terraform the Earth again.]]

* The Pupa from ''WesternAnimation/SolarOpposites'' is designed to eventually turn Earth into a duplicate of the planet Shlorp. [[spoiler: "99 Ships" reveals that the Shlorp the main characters come from isn't the original one, not by a long shot. There have been ''thousands'' of Shlorps which repeatedly get [[EarthShatteringKaboom destroyed]], after which teams are sent out with Pupas to make a new Shlorp.]]

** It is revealed that had Earth become a Gem colony as planned, it would have been completely gutted to serve the Gem homeworld's purposes. The [[StoryboardingTheApocalypse graphic simulation]] shows us a world that is nearly hollowed out, to the point that it can only charitably be called a planet at all, with Gem technology covering what's left. We don't know how many inhabited worlds have met this end. While the Crystal Gems managed to save the Earth, in-universe maps show that the Earth's geography was still drastically altered — most prominently, Siberia has largely sunk.
