->''"If you were going to take over the world, would you blow up the White House ''Film/IndependenceDay''-style, or sneak in through the back door?"''
-->-- '''Casey''', ''Film/TheFaculty''

One of the [[OlderThanTelevision oldest stories]] in SpeculativeFiction: Beings from space come to Earth to conquer.

'''There are a few ways this can go:'''
* The All-Out Attack. Technologically superior forces aim their weapons of war and [[TripodTerror three legged walkers]] at Earth, which bravely fights back, driving them off through cunning, bravery, or just dumb luck... [[TheBadGuyWins most of the time]].
* The Infiltration. Aliens are replacing, [[{{Brainwashed}} brainwashing]], or [[PuppeteerParasite controlling]] humans in order to take over from within. Generally, the populace at large [[{{Masquerade}} doesn't even know it's happening]]. May involve TheVirus.
* A combination of the above, with an infiltration paving the way for an all-out attack.

Sometimes, there are good aliens that help us against the invaders; unfortunately, they tend to be much weaker and/or less numerous, since if they were equally or more powerful, the focus would be taken off humanity. Then there's the BenevolentAlienInvasion, where the invaders ''are'' the good aliens.

Often an allegory for some Earth-based conflict, either one that's happened in the past or one that people fear may happen. The Infiltration is especially popular as a metaphor for Communism.

This trope, in its modern form, was created by Creator/HGWells's novel ''Literature/TheWarOfTheWorlds''. It was actually a variation on another theme popular at the time, the "[[DayOfTheJackboot invasion story]]", where another country's army, usually France or Germany (depending on [[RippedFromTheHeadlines who relations were worse with at the time]]), would try to conquer Britain. [[TooSoon Then]] UsefulNotes/WorldWarI [[HarsherInHindsight happened.]] Today, similar themes are found in techno-thrillers, and crop up in works like ''Film/RedDawn1984'' and ''Literature/TheTomorrowSeries''.

A common TomatoSurprise nowadays is for [[HumansAreTheRealMonsters the invaders to be human]].

[[folder:Anime & Manga]]
* ''Manga/AxisPowersHetalia: [[BigDamnMovie Paint It White]]''. The plot involves an alien invasion of Earth in which about [[KillAllHumans 90% of the global population]] and their countries are transformed into what looks like [[FacelessMasses white featureless humanoid clay]], known as [[TheGreys the Pict]]. In the final scene of the movie, billions of converted Pict can be seen walking into a giant mothership [[AliensAreBastards which then]] [[AlienAbduction departs Earth]] after [[OnlyTheLeadsGetAHappyEnding our heroes save the day]]. So even with the "happy" ending, there are still [[InferredHolocaust only a few hundred million people left on Earth]]. And [[TrueNeutral the Swiss]]. And Iceland.
* In ''Anime/{{Bakugan}}''. After the BigBad was destroyed in the first season finale, the next two seasons had extradimensional aliens as their main villains.
* A Type 3 in ''Manga/CannonGodExaxxion'', which draws some (narratively intentional) parallels to 19th-century colonialism. The manga milks these for all it's worth.
* In ''Anime/{{Daimos}}'', the Brahmins (an alien race of {{Winged Humanoid}}s) had no intention of invading Earth and wanted negotiating a peaceful settlement. However, the death by poisoning of their Emperor and the belief of Terrans had assassinated him changed that.
* Subverted in ''Manga/DragonBall'', with Raditz being the first invader and being killed by Piccolo and [[HeroicSacrifice Goku]] anyway. A year after that, Vegeta and Nappa invaded the earth and they destroyed a city immediately. Unlike Raditz who was looking for his brother Kakarot/Goku, Vegeta and Nappa just wanted to find the [[MacGuffin Dragon Balls]].
** After hearing from the Dragon Balls, Freeza and his minions invaded Namek and stole the balls in a very brutal way. They killed almost every Namekian - some of them were killed by Vegeta, the Grand Elder died of old age, but his death was accelerated by Freeza's invasion, and Nail being the only survivor ([[DeathIsCheap all of them were revived, anyway]]). Except for the Namekians killed by Vegeta, since he was not one of Frieze's men, and Nail fused with Piccolo so he all by ceased to exist. The Grand Elder also died permanently not long after his revival.
*** Frieza's arrival on Earth with his army in ''Anime/DragonBallZResurrectionF'' is explicitly called an invasion.
** Goku's arrival on Earth was supposed to be an alien invasion/genocide until he hit his head and forgotten his mission.
** This scenario happened in some of the {{Non Serial Movie}}s, most notable are the invader groups of [[Anime/DragonBallZTheTreeOfMight Tarles]] and [[Anime/DragonBallZLordSlug Lord Slug]]. The former almost dried off the entire earth with a WorldTree, and the latter had actually a real army and he frozes the planet by darkening the sky with black clouds.
*** Paragas and his army invaded some planets, his son [[OmnicidalManiac Broly]] destroyed them anyway.
*** Another notable example: Janemba messed up with the Living World and Other World, causing that the killed villains invaded earth, including the {{Big Bad}}s and their respective armies.
** The alien wizard Babidi and his minions, a couple of whom are also aliens, sneak onto Earth to retrieve and revive Babidi's father's LivingWeapon Majin Buu.
* In the ''Anime/EurekaSeven'' TV series, the Scub Coral drove humanity off of Earth for 10,000 years (unintentionally) when it arrived. It grew and formed an outer layer around Earth, fooling humanity into thinking it was another planet when they returned and settled on the new surface. The Scub Coral later spawned human Coralians to live among humans to study and communicate with them. The BigBad uses this planet takeover history to justify his actions against the Scub Coral which was just trying to communicate with humanity.
* ''Manga/{{Gantz}}'': The various aliens that appear in the manga series. It is not known when, how and why the aliens appear on Earth. The aliens use a variety of technology and abilities to infiltrate the earth where the Gantz team hunts them. [[spoiler: Later HumongousMecha land on Earth and begin to level the planet.]]
%%* ''Anime/GEARFighterDendoh''
* In ''Manga/{{Gintama}}'' the story is set in an alternate late Edo period where is attacked by aliens called "Amanto" ("Sky People"). The samurai of Japan join the battle against the aliens, but when the Shogun realizes the power of aliens, he betrays the samurai and surrenders to the aliens. The Shogun writes an unequal contract with aliens which allows the aliens to enter the country and places a ban on carrying swords in public.
%%* ''Anime/{{GoLion}}''
* ''Manga/{{Heroman}}'' has the Earth attacked by BigCreepyCrawlies and giant spheres of doom.
%%* ''Anime/MiraiRoboDaltanious''
* Subverted in Dowman Sayman's ''Paraiso''. In simple [[{{Yonkoma}} 4koma]] format, the audience is shown a schoolgirl attempting to [[SchoolgirlLesbians take down another girl]] and [[BlackComedyRape rape her]]. As this is happening, a nearby UFO's [[TheGreys occupants]] are shown [[RapeIsASpecialKindOfEvil being repulsed]] and stopping whatever plans they had for a future invasion.
* ''Manga/{{Parasyte}}'': Infiltration by aliens called parasites which are worm-like creatures that enter human bodies and transform their brain, killing them. They then go about disguised as their host secretly eating other humans.
* ''Anime/PokemonDestinyDeoxys'': Rayquaza thinking this is happening is what kicks off its conflict with [[StarfishAliens Deoxys]].
* ''Anime/ProjectBlueEarthSOS'' is essentially a homage to 1950s/1960s-style science fiction shows, with two [[KidHero kids]] acting as the main protagonists and finding out about the incoming invasion and doing everything they can to stop it.
* In ''Anime/SamuraiFlamenco'' aliens have taken control of governments all over the globe, and Japan was the last stand until the Prime Minister was defeated.
* In ''Manga/SevenBillionNeedles'', the alien Maelstrom takes a host and then goes on a killing spree. Horizon follows him an attempt to stop him. [[spoiler: Repeat ad infinitum.]]
* Parodied in ''Manga/SgtFrog''. The main character is the alien-frog Sergeant Keroro, the leader of a recon team for an alien invasion from Keron, "the 58th Planet of the Gamma Nebula". But once his superiors realize he's been found out, they abort the mission and leave him and his crew behind. With no one else to turn to, Keroro ends up staying at the Hinata house with Fuyuki, Natsumi, and their mom Aki, living as something between a servant and a pet. He reunit with his squadron and still plot to take over the Earth....when he's not doing chores for the Hinata family or is distracted by such aspects of Earth culture as ''Gundam'' model kits and the Internet.
%%* ''Anime/ShinkonGattaiGodannar''
* Set in 2199, ''Anime/SpaceBattleshipYamato'' see a long battle against an alien race known as Gamilas that has redcued the Earth to an uninhabitable radioactive wasteland.
* ''Anime/SuperDimensionFortressMacross'' is also a deconstruction of this trope; it shows what would actually happen if a vastly superior alien race (which spends the majority of the series showing restraint, gathering intelligence, and generally being [[HumansAreTheRealMonsters more reasonable than the Earthlings]] despite being genetically programmed for war) decides that Earth is a threat. [[spoiler: Earth gets slagged, wiping out all of humanity in a single barrage. Only the titular Macross and her crew and refugees survive]]
* ''Anime/UFORoboGrendizer'': An early Anime example and the third series of the ''Anime/MazingerZ'' trilogy. The Vega homeworld had become unstable due to the radioactive materials within it and the King decided to expand his militaristic empire to find a suitable planet to settle on. The main character lived in Fleed, one of the first planets the Vegan army attacked and was forced to run away. He landed on Earth and settled peacefully in there. Then two years later the Vegan army struck his new homeworld.
* ''Manga/UruseiYatsura'' starts the unlucky (and pervert) boy Ataru chosen by lot to challenge a band of alien invaders from the planet Oni in a game of tag to decide the fate of the Earth. His opponent: the lovely Princess Lum, daughter of the Onis' leader, Mister Invader. He win, but make also an AccidentalProposal to Lum that fall in love with him...and the rest is history.
* In ''Manga/WorldTrigger'', Earth is caught in the middle of a vast interplanetary war.

** It also features the Xerbians in the role of the good aliens. Sadly the Xerbians are the survivors of a previous Evronian invasion and have little military power left (their help is more [[spoiler: attempting to]] FlingALightIntoTheFuture). Then there's Xadhoom, a Xerbian who had missed the invasion due an experiment that made her a PhysicalGoddess and wants to [[RoaringRampageOfRevenge exterminate the Evronians to the last]]...

The God Emperor of Mankind must rally His people and deliver Humanity from its [[http://forums.sufficientvelocity.com/threads/in-the-beginning-there-was-man-wh40k-x-sc-aka-omake-quest-aka-40k-warp-god-waifu-simulator.9721/ darkest hour.]]

* The ''Fanfic/PonyPOVSeries'': During the Dark World arc, it's revealed that at some point during the [[BadFuture Epilogue timeline]], Equestria was invaded by what is strongly implied to be the [[TabletopGame/{{Warhammer40000}} Imperium of Man]]. This forced all of [[EvilOverlord Discord's]] remaining enemies to [[EnemyMine ally with him]] in order to repel the invasion, which they eventually succeeded in doing.
* In ''[[Fanfic/TheLionKingAdventures The Lion King Adventures]]'' story ''The Master Plan'', an alien parasite known as the Vimelea attempts to invade the earth by possessing [[spoiler: Mufasa and Sarabi.]]

* ''Fanfic/YoungJusticeDarknessFalls'' points out that this has become a recurring issue for the league, with first the kroletaens, then the reach, then Despero, then Mongul, then Starfire, and finally Darkseid all being threats that came via alien invasion to their planet. ComicBook/BlueBeetle even gives a little note to Starfire that 1 is more than enough for a year. (Star ends up being good, but that's besides the point)
* ''Fanfic/{{Worldfall}}'' features two ''simultaneous'' alien invasions of Earth by the [[Literature/{{Worldwar}} Race]] and [[Literature/{{Footfall}} Fithp]].
* ''Fanfic/WarboundWidow'' has this happen with planet Earth via the Alternian Empire, which kickstarts the plot.
* ''Fanfic/EquestriaAcrossTheMultiverse'' features an extradimensional variant when the Flim Flam Brothers from their TheBadGuyWins timeline from the Season 6 finale launch an invasion of mainline Equestria with a robot army and assisted by one of [[BigBad Ispita's]] sons. They have apparently done this to a larger number of worlds by this point, but Mainline Equestria ultimately proves too much for them.

[[folder:Films -- Animation]]
* ''WesternAnimation/MonstersVsAliens'': An animated film that portrays and alien invasion by Gallaxhar seeking out the last remaining sources of [[{{Unobtanium}} quantonium]]. The invasion starts off with a giant robot sent to reclaim the remaining quantonium. [[spoiler: Later the main character is kidnapped and has the quantonium she absorbed extracted from her allowing the villain to clone an invasion army from himself.]]
* Inverted in ''WesternAnimation/BattleForTerra'', where it's the humans who are invading the titular planet (not [[PlanetTerra Earth]]).
* ''Animation/WarOfTheWorldsGoliath'' is a sequel to ''Literature/WarOfTheWorlds'' and has both the original invasion (as seen in the opening) and the one the movie focuses on.


[[folder:Films -- Live-Action]]
* {{Inverted|Trope}} in ''Film/{{Avatar}}''. The technologically-advanced humans colonise the moon of Pandora [[PlanetLooters seeking to mine out a rare ore]]. When diplomacy with the [[NobleSavage native, peace and nature-loving Na'vi]] breaks down, the GeneralRipper steps in and declares war on them, [[spoiler:destroying their home and killing thousands of them, elderly and children included. Only barely do the Na'vi succeed in pushing the human invaders off their planet, and even then, at great cost]].
* ''Film/BattleLosAngeles'': The alien invaders land off the coast of California and immediately launch a military offensive. The movie is notable for being reasonably accurate in its presentation of the military and the aliens operating as a military force. They also bring in tens of millions of soldiers, something that would be required to take over and control a planet of billions.
* The aliens in ''Film/{{Battleship}}'' appear to be an advance scout force whose task is to notify their homeworld about humanity's defenses in preparation for an actual invasion.
* ''WesternAnimation/Ben10'' [[LiveActionAdaptation live-action movies]]:
** In the first ''[[Film/Ben10RaceAgainstTime Race Against Time]]'', it is time-traveling creatures of which the leader needed to activate a specific device to make the invasion happen.
** In the second movie, ''[[Film/Ben10AlienSwarm Alien Swarm]]'', it is [[NanoMachines alien nanochips]].
* ''Film/EdgeOfTomorrow'' is a typical example of an alien invasion with the aliens having extremely advanced technology, and human militaries are barely holding on.
* A recurring trope in the Franchise/{{Godzilla}} films, always featuring hostile aliens finding a way to use {{Kaiju}} as weapons against humanity:
** ''Film/InvasionOfAstroMonster'': aliens from Planet X use MindControl to sic Godzilla, Rodan and King Ghidorah on the Earth after pretending to come in peace.
** ''Film/DestroyAllMonsters'': aliens from the planet Kilaak set up a base on the moon and initially take control of 10 monsters native to Earth and send them to attack different cities around the world, then dispatch King Ghidorah as their ace in the hole when the other monsters are freed from their influence.
** ''Film/GodzillaVsGigan'': aliens from the Space Hunter Nebula build a weaponized headquarters on Earth ([[ItMakesSenseInContext which looks like a giant statue of Godzilla]]) then try to demolish Tokyo with King Ghidorah and Gigan.
** ''Film/GodzillaVsMechagodzilla'' and ''Film/TerrorOfMechagodzilla'': aliens from a planet consumed by a black hole try to conquer Earth using Mechagodzilla, a colossal robot shaped like Godzilla, and Titanosaurus, an Earth-born monster they can control.
** ''Film/{{Godzilla 2000}}'': in a twist on the formula, the invading alien Orga ''is'' a giant monster itself, with its own ship and goals beyond just fighting Godzilla. Orga is able to download huge amounts of data about humanity off the internet using its ship, with plans to conquer the planet solo once Godzilla is dealt with.
** ''Film/GodzillaFinalWars'' has a reimagined version of the Planet X aliens basically pulling the exact same plan as the Kilaaks, but with the addition of a huge fleet of warships and fighter crafts just as dangerous as the monsters. Again, Ghidorah is the big gun pulled out during the climax.
* ''Film/IndependenceDay'':
** The aliens send several massive ships over major cities. They then use powerful WaveMotionGun to destroy the cities. They later launch assault with fighter craft to attack the human military attempting to fight back.
** They're back in ''Film/IndependenceDayResurgence'', set 20 years later. Humanity has rebuilt in the meantime and was able to study and adapt some of the alien tech, but the second alien force appears to be much larger than the first one.
* ''Film/InvasionOfTheBodySnatchers'': Is one of the most famous versions of The Infiltration as [[RedScare Communist metaphor]]. Humans are kidnapped and replaced with alien lookalikes..
* ''Film/InvisibleInvaders'': [[{{Invisibility}} invisible]] aliens attack the earth by [[PuppeteerParasite possessing corpses]]
* ''Film/ItCameFromOuterSpace'' (1953) : A subversion where the aliens appear to be carrying out a classic Infiltration-style attack, but are only trying to quietly repair their spacecraft which crashed due to a malfunction.
* ''Film/{{Knowing}}'': Aliens have been secretly visiting Earth to prepare themselves in to extract the chosen life forms from Earth in light of the Earth's destruction by the Sun. They disguise themselves as humans to do so (though they never speak human language).
* ''Film/LittleShopOfHorrors'' (1986): [[spoiler: In the ending it is revealed that the plant is an alien invader that is using infilitration to conquer the planet by having humans unwittingly spread its seeds around the world.]]
* In ''Film/ManOfSteel'', Zod comes to Earth in search of Clark, aboard a CoolStarship with a WaveMotionGun.
* ''Film/MarsAttacks'' : A parody which drew inspiration from the trading cards of the same name. Like the trading cards the movie portrays a military invasion by the Martians.
* Several examples in the Franchise/MarvelCinematicUniverse:
** ''Film/{{The Avengers|2012}}'': Loki brings the aliens known as the Chitauri to Earth to act as "his" army. Loki wants to rule Earth to spite his brother Thor, while the Chitauri merely want the Tesseract, so that they can conquer ''other'' worlds.
** ''Film/ThorTheDarkWorld'': The Dark Elves attack London in order to use Earth as a staging point for unleashing the Aether to [[OmnicidalManiac destroy the whole universe]].
** ''Film/AvengersInfinityWar'': Thanos invades Earth in order to gather the Infinity Stones hidden there.
* In ''Film/{{Oblivion 2013}}'' Earth has been invaded by a race called the Scavs. The setting is in the aftermath, about 60 years afterwards. [[spoiler: Or so Jack believes. Turns out, the AlienInvasion was actually by the Tet, a giant autonomous AI, and the Scavengers are the human resistance.]]
* ''Film/PacificRim'' has a race of beings from another dimension create progressively-larger {{kaiju}} to obliterate humanity and prepare Earth for their arrival. They get to Earth through a portal at the bottom of the Pacific.
* ''Film/{{Pixels}}'' involves the aliens misinterpreting the recordings of arcade games from TheEighties as a hostile message and modeling their attack on Earth as classic video game characters, such as VideoGame/PacMan and VideoGame/DonkeyKong. Creator/AdamSandler and Creator/KevinJames assemble a team of retrogamers to fight them with video game-inspired weapons.
* ''Film/{{Signs}}'':The aliens attempt a military invasion but are stopped by their crippling [[WeaksauceWeakness vulnerability to water]].
* ''Film/{{Skyline}}'': A military invasion aided by a blue light that mesmerizes humans allowing the aliens to suck them up into their ships. They also use large walking life forms and squid like entities on the ground. Is getting a sequel called ''Beyond Skyline''.
* ''Film/SpacedInvaders'' is a comedy about a crew of inept Martians who intercept a rebroadcast of Creator/OrsonWelles's ''Radio/TheWarOfTheWorlds'' radio drama and assume their fleet is attacking Earth (in fact, their fleet is in the process of being obliterated by their enemy the Arcturians). They crash-land in a small American town and begin their "invasion". HilarityEnsues.
* ''Film/{{Slither}}'': The alien invader uses infiltration by taking over human beings. The movie Includes a {{homage}} to the movie "Thing", by naming the town's mayor after Kurt Russell's character, R. J. [=MacReady=]. A character who gets a glimpse into the mind of the creature reveals that they have already taken over several other planets.
* Inverted in ''Film/StarshipTroopers''. After a series of attacks on human colonies and a direct attack on Buenos Aires on Earth, humanity declares war and invades the bug worlds.
* ''Film/TheyLive'': Space aliens use infiltration via technology and manipulation of the human mind to take over or place themselves in places of power.
* ''Film/TheThing1982'': A strange alien found in the artic with the ability to mimic any living creature. Whether it intended to go to Earth in the first place is unclear. It still threatens to take over.
* ''Film/TransformersDarkOfTheMoon'': Everyone's favorite evil robots, the Decepticons, decide to give the All Out Attack a shot. The Autobots are of course the good aliens helping out humanity here.
* The main plot in ''Film/WarCraft2016'' is alien invasion, [[RecycledInSpace Fantasy-style]]. The orcs come from another world, want to use the local population to bring the rest of their Horde to Azeroth, and then intend to (or at least Gul'dan intends to) magically terraform their new home in Draenor's image.
* ''Literature/TheWarOfTheWorlds'': A early work with aliens initiating a military invasion of the earth.
* ''Film/TheWhispererInDarkness'' (2011). The Mi-Go plan to open a wormhole to Earth to bring through an invasion force. This is different from the short story by Creator/HPLovecraft in which they've already decided the conquest of Earth is too much trouble.
* In ''Film/TheWorldsEnd'', extraterrestrial machines have invaded a small town in England. [[spoiler:And 20,000 other locations on the planet.]]

* Subverted in the ''Literature/ChooseYourOwnAdventure'' book ''Invaders of the Planet Earth''. The Taurons have conquered Earth and rendered all electrical devices useless since their own technology is [[WeaksauceWeakness extremely vulnerable to the slightest exposure to electricity]]. The protagonist in most paths tries (and mostly fails, this is one of the less forgiving books in the series) to find a way to defeat the Taurons. However, in one path [[spoiler:which is canon according to the sequel ''Planet of the Dragons'']], the protagonist has a chance to get the Taurons' side of the story. The Taurons were actually pursuing a very dangerous criminal (a member of the "good" Vork aliens opposing the Taurons) who found his way to Earth. The Taurons' occupation of Earth was merely a desperate attempt to keep the criminal trapped on Earth while they hunted him down. He is apparently so dangerous some Taurons want to ''destroy Earth'' just to get rid of him. The end of this path has the protagonist joining the very aliens he originally opposed.

* ''Literature/AllTomorrows'':
** The Qu are ScaryDogmaticAliens who are on a mission to remake the universe as they see fit, humans included. [[spoiler: [[TheBadGuyWins They Win.]]]]
** The homeworld of Bug Facers was at one point invaded by an alien species. The Bug Facers won, but the invasion left them with a deep, species-wide paranoia where extraterrestrial species were concerned.
** The Gravital are [[OmnicidalManiac Omnicidal Maniacs]] who want to destroy all other intelligent life in the galaxy. [[spoiler: Their extreme level of technological advancement made wiping out most of the other human species trivially easy.]]
* ''Literature/{{Animorphs}}'': The aliens use infiltration, with only five kids armed with alien technology and one helpful alien available to fight the threat.
* ''Literature/ArrivalsFromTheDark'': ''Invasion'' by Creator/MikhailAkhmanov: The novel details the arrival of a giant HumanAlien starship from another galactic arm in order to conquer and enslave humans, who only have a tiny fleet of ships with no shields, AntiMatter, or FTL capability. After the humans barely survive (thanks to [[spoiler:another alien]]), the following novels chronicle humanity using the leftover technology to build an interstellar empire (well, more of a [[TheFederation federation]] but with GunboatDiplomacy).
* ''Auf zwei Planeten'' ("On Two Planets") by [[Creator/KurdLasswitz Kurd Laßwitz]] was published a year before ''War of the Worlds'' and is probably the first subversion of the genre: It turns out the Martians [[BenevolentAlienInvasion really are more advanced then humans]].
* ''Literature/BattlefieldEarth'': Has two of them, one a thousand years before the book starts when the evil [[MeaningfulName Psychlos]] took over the planet, and then a coalition of other races swoop in after humanity retakes Earth. Thought it is more of an [[EasilyThwartedAlienInvasion Alien Incursion or Alien Fracas]] than an all-out invasion in the second case, as the alliance is more interested in leftover Psychlo plunder and selling the humans into slavery than the planet itself.
* ''Literature/{{Bolo}}'' book series: Several of the all-out invasion variety occur in the stories, one ultimately resulting in a near mutual genocide of humanity and their alien opponents.
* ''Literature/ChaosSquad'': Alien invaders nicknamed the X during wartime.
* The Hch'nyv from the [[TrilogyCreep fourth book]] of ''Literature/TheDarkswordTrilogy''. They are basically an alien invasion taking place in a fantasy setting. Almost all of their actions take place offscreen, but from what little is mentioned about them, they seem to go for the all out attack.
* In the early ScienceFiction story LesXipehuz (from 1888), the eponymous beings nearly wipe out humanity. It's not clear if they are indeed aliens, but they are strange enough to count as StarfishAliens and if they indeed are alien, it makes the story one of the first examples of this trope.
* ''Literature/{{Doom}}: Hell on Earth''. As the name implies, is about the aliens and their genetically-engineered-to-scare-humans creations attacking planet earth.
* In ''Literature/EdenGreen'', needle monsters make rare appearances on the edges of a recession-hit city. But before the main characters can figure out where the monsters are coming from and how to effectively kill them ''en masse,'' [[spoiler:the floodgates open and the city is hit with hundreds of monsters at once]]. The invasion and its aftermath are explored extensively in the web serial ''Literature/CityOnTheEdgeOfNowhere'' and sequel novel, ''Literature/NewNight''.
* ''Literature/EndersGame'':
** It takes place after ''two'' barely-thwarted invasions by the Buggers/Formics. The titular character is part of a program to train commanders in preparation for the Third Invasion. Subverted in that [[spoiler:the Buggers have no intention of attacking again, having experienced a WhatHaveIDone moment after realizing that humans are not a HiveMind like them but a collection of individuals. The Third Invasion is the reverse with humans sending a fleet to take out the Buggers]].
** The prequel novels ''Literature/FormicWars'' describe the First Invasion (although differently from how it's remembered in ''Ender's Game'').
* ''Literature/{{Footfall}}'': The 1985 Creator/LarryNiven / Creator/JerryPournelle novel has a [[MohsScaleOfSciFiHardness hard science]] look at this trope; the elephant-like Fithp ruined their own planet and have come in a [[GenerationShips SleeperShip]] to claim ours. A military type invasion is launched against the earth.
* ''The Greks Bring Gifts'' has a unique form of infiltration; [[spoiler:they make humanity dependent on their deliberately flawed technology]].
* ''Literature/LegacyOfTheAldenata'' by Creator/JohnRingo is initially presented as a BenevolentAlienInvasion, but not too far into the first book of the series hints start showing up that the [[CorruptCorporateExecutive Darhel]], the putative leaders of the [[TheFederation Galactic Federation]], have other plans, which aren't terribly beneficial to mankind. Earth is also invaded by the rapacious Posleen who conquer and devour their way across the galaxy. This invasion folds into the plans of the Darhel.
* ''Literature/ThePuppetMasters'' by Creator/RobertAHeinlein: A novel made into several movies. Of course, one of the major problems with making it into a movie is that near the end ''everyone'' [[AuthorAppeal walks around naked]] all the time, as it is a defense against the aliens. The aliens use, if you haven't guessed, the infiltration method.
* In ''Literature/ThePuppiesOfTerra'' (a.k.a. ''White Fang Goes Dingo'') by Creator/ThomasMDisch, highly advanced energy beings take over earth with no difficulty at all. They're a race of aesthetes--they behave exactly like late-Victorian gay males--and [[spoiler:they abandon Earth when humans will simply ''not'' cease thinking about disgusting things]].
* Played horrifyingly straight in ''Literature/RememberToAlwaysBeBrave''. And the characters feel that the invasion is due to a non military organization/corporation - and yet that non-military entity nearly wipes mankind out of existence.
* In Creator/HarryTurtledove's "Literature/TheRoadNotTaken" short story, the [[InsufficientlyAdvancedAlien Roxolani]] try to invade Earth, first by impressing humans with their ArtificialGravity-powered ship and then by their advanced weapons. These advanced weapons? Napoleonic muskets and appropriate tactics. To say "EasilyThwartedAlienInvasion" would be an understatement.
* One of the books in Creator/HarryHarrison's ''Literature/TheStainlessSteelRat'' deals with a full-blown invasion of human space by hyper-advanced (even by human standards) ugly-looking aliens. In a slight subversion, it's revealed that [[spoiler:they're under the MindControl of a rogue human faction]]. Once the ManBehindTheMan is taken out, the aliens decide that maybe they don't feel like fighting any more.
* Subverted in ''Supreme Commander'' by Nikolai Gudanets, loosely based on ''VideoGame/XCom''. This is the initial assumption for the alien attacks, and an international task force is created to combat them. When a new type of alien is taken captive, they find a way to communicate with it, and it reveals that the aliens are, in fact, HuntingTheMostDangerousGame. They have no interest in Earth beyond treating it like a fun outing. They do have a base on Earth, but it's actually a re-purposed Nazi sub pen far north.
* ''Literature/TheTrueMeaningOfSmekday'': The Boov aliens are speaking to Gratuity's mother through a mole in her neck. They then abduct her to teach them English. Then they invade and force all the humans onto reservations in Florida. [[spoiler: Then even more powerful aliens invade.]]
* In Creator/VernorVinge's novella "Literature/TrueNames", this is discussed as one possible explanation for The Mailman's peculiar method of communication with the on-line world of The Other Plane. In particular, the time-lag would seem to place him in the Asteroid belt, far beyond where any human has visited.
* ''Under Alien Stars'' a young-adult novel by Pamela Service: The planet is [[VichyEarth annexed as a military base]] by [[AmazingTechnicolorPopulation magenta-skinned]] HumanoidAliens who are fighting a BugWar. Although generally [[AliensAreBastards arrogant, callous, quite willing to wipe out whole neighborhoods]], and by ''no'' means fit the usual idea of a BenevolentAlienInvasion, they're by far the [[BlackAndGrayMorality lesser of evils]] compared to their foes. [[spoiler:Not that [[HumansAreTheRealMonsters humanity doesn't have to find that out the hard way]] before the two races finally team up against the common enemy...]]
* ''Literature/TheWarOfTheWorlds'': The TropeMaker and one of the earliest sci-fi novels. The alien tripods attack earth in a military invasion.
* ''When Literature/TheTripods Came'': The tripods utilize infiltration by mind control. A tv show is used to assert temporary control with caps used to assert permanent control. The populace is manipulated with the mind control until “The Capped” are in control in a majority of places.
* ''Literature/TheWildBoy'': The Lindauzi, who killed off millions with a virus, then showed up with a cure to draw what was left of humanity to them. After getting rid of humanity's companion creatures, they began keeping humans like dogs and breeding them to be replacement bond creatures for themselves.
* The ''Literature/WorldWar'' series by Creator/HarryTurtledove: The aliens invade during UsefulNotes/WorldWarII and this forces the warring sides to [[EnemyMine unite against them]]. Also, the aliens are deliberately given contemporary (at time of writing, i.e. 1994) levels of technology plus a little extra to allow them to travel between stars, rather than the usual insanely advanced aliens vs. present day humans. They are also really, [[TheyChangedItNowItSucks conservative]]. Like, they've been ruled by the same dynasty for [[SciFiWritersHaveNoSenseOfScale tens of thousands of years]] and are surprised that humans have advanced from the medieval era to the present in only a few hundred years, conservative. [[spoiler:By the end of the initial four-book series, the three superpowers (US, USSR, and Nazi Germany) manage to force the Race into a stalemate. Four books after that, and a human FTL-capable ship arrives to the Race's homeworld in a clear case of GunboatDiplomacy.]]
* ''Literature/WeKnewTheyWereComing'': Humanity gets some advance notice of the alien fleet, fires first and accidentally nuke the world. Surviving bombardment and nukes is as much a part of the story as eventually fighting back.
* In Creator/DavidWeber's ''Literature/OutOfTheDark'', the last time Earth was surveyed was in 1415. The peaceful aliens were so disturbed at the human savagery they observed at the Battle of Agincourt that, 600 years later, they granted the predatory Shongairi the right to colonize Earth and subjugate its supposedly primitive population. When the Shongairi fleet arrives, they are shocked that humans are both far more advanced than expected (developing at triple the standard rate) and not as advanced as expected in certain areas (despite the discovery of nuclear power, we still continue to burn fossil fuels). While galactic law forbids colonizing a Stage 2 civilization like 21st century Earth, the Shongairi commander points out that the permission given to him by the other races doesn't actually specify the required stage, so he uses a LoopholeAbuse to justify attacking Earth, figuring that the more peaceful races will be glad that humans are pacified regardless.

[[folder:Live-Action TV]]
* ''Series/The100'' [[PlayingWithATrope plays with the trope]]. The aliens are actually human beings descended from 21st Century astronauts, but they otherwise fit the trope to a T: they come from space, are more technologically advanced than the people of Earth, and intend to (re-)colonize the planet. They don't think of themselves as invaders, though: they've always thought of Earth as their real home, even if no living person among them has been there before, and when they first send people down to the planet, they thought Earth-based humanity had long since died out. It's not until one of Earth's natives gives them a WhatTheHellHero moment that they realize how much they've been playing the alien invader role.
* Series/ArrowVerse:
** An epic {{crossover}} event between ''Series/TheFlash2014'', ''Series/{{Arrow}}'', ''Series/LegendsOfTomorrow'', and ''Series/{{Supergirl|2015}}'' aptly titled "Invasion!" deals with an attack by a race of hostile aliens called Dominators, necessitating Barry to gather an all-star team, composed of Team Flash, Team Arrow, the Legends, and Supergirl. Kara mentions that they also exist in her home universe and have attacked Krypton in the past. The Dominators have previously come to Earth in the 50s in Redmond, Oregon. The US Army attempted to stop them only for several hundred soldiers to be slaughtered and their bodies dragged away. They appear to attack civilizations with the potential to eventually challenge them. In the case of the Kryptonians, it's because they gain superpowers, when exposed to yellow suns. In the case of humans, it's because of metahumans. They are also somehow able to tell that [[spoiler:Barry has changed history]].
** Additionally, in ''Legends of Tomorrow'', there's a possibility of an invasion from the planet Thanagar in one particular BadFuture. Thanagar also exists in Supergirl's universe, by the way.
** Near the end of ''Supergirl'' Season 2, a fleet of [[spoiler:Daxamite]] ships arrives and attacks National City, and it all started because [[spoiler:Mon-El didn't want to go home with his mom and dad]]. Supergirl ends up stopping the invasion by [[spoiler:using a device modified by Lena to saturate the atmosphere with trace amounts of lead, which is lethal to Daxamites, but Mon-El is forced to leave the planet]].
* ''Series/{{Colony}}'' takes place several years after an event called the Arrival, during which an alien race known only as "the Hosts" attacked and defeated all the world's militaries in about [[TheShortWar eight hours]]. Now, the survivors are herded into sealed off cities run as {{Police State}}s by LesCollaborateurs, under threat of OrbitalBombardment. Part of the show's mystery is the question of just ''why'' the Hosts invaded.
* ''Series/DarkSkies'': A series on NBC was pretty much a textbook infiltration, infiltrating with parasites and (at the end) electronic implants. The point of the series was that many of the events of the 20th century were secretly part of the infiltration, such as the Kennedy assassination.
* ''Series/DoctorWho'' has featured invasions from such things as shop dummies to satellite navigation systems. The series also inverts this tropes in many future-based stories, humans are themselves the invaders. They're usually not outright malicious, but often quite destructive to native species, paralleling historical imperialism and colonization. Notable invasion-themed serials:
** "The Sensorites": The first "alien invasion" story. The humans are the invading aliens, with the relatively peaceful Sensorites shown as mild-mannered victims.
** "The Dalek Invasion of Earth" plays it absolutely straight -- Daleks invade the Earth and it's up to LaResistance and the TARDIS crew to stop them.
* In an episode of ''Series/EarthFinalConflict'', two characters end up in an alternate universe where the [[EnergyBeings Taelons]] are in the process of conquering Earth through their [[LesCollaborateurs human subjects]] with LaResistance actually having more advanced weapons technology than Prime!Earth. Despite this, the Taelons are clearly winning. In the Prime universe, the Taelons come to Earth bearing gifts and claiming to seek peacefull cooperation. Their true motives remain hidden. The key point appears to be the arrival of an ancient Taelon named Ma'el to Earth in the Prime universe, which he never did in the alternate one. Ma'el, apparently, encouraged humans to urbanize and form centralized civilizations in order to resist the arrival of Taelons in the future. The alternate humans live in villages with the closest equivalent of cities being trading centers.
* ''Series/FallingSkies'': A TNT Show takes place about six months after an alien invasion devastates most major cities and wipes out a large percentage of the population. The show describes a ragtag group of survivors trying to find food and shelter to get by, while avoiding murderous aliens and roving bands of outlaws and trying to survive and fight back. While the series avoids showing the actual invasion (the background is told by a child and a series of drawings in the pilot), it involves huge circular {{Ominous Floating Spaceship}}s appearing over major cities. They hang there for a while, but the world leaders decide not to strike first, hoping the aliens are friendly. They aren't. The ships emit powerful EMP waves, shutting down power grids and defense systems before proceeding to obliterate most major cities. They land ground troops with infantry and mechs (the survivors note that the mechs are bipedal, despite the aliens having 6 legs) that proceed to wipe out much of the adult population, while capturing children and putting MindControl harnesses on them (presumably, to make them slaves). The large ships depart, while the invading forces begin constructing large structures in places of destroyed cities. The human survivors are forced to retreat and use only basic weaponry (rifles, machineguns, and C4), as any heavy munitions tend to piss off the aliens, and their bombers simply level the entire area. It's eventually revealed that [[spoiler:the actual aliens are indeed humanoids; the Skitters are mutated human children]].
* ''Series/FirstWave'': Presents an infiltration approach. The Gua aren't quite sure what to expect from humans and are trying to find ways to weaken Earth's defenses. Their goal is turn humans into slaves in preparation for an all-out attack.
** One episode revealed that the government was secretly preparing for an alien attack, building a series of satellites armed with nukes which were set to face away from Earth. However, [[spoiler:the Gua have no intention of attacking in a typical manner. Their goal is to grow an army of husks on Earth and start the invasion that way]].
** It's revealed early on that the Gua have themselves suffered this. After throwing off their oppressors, they have sworn to never be weak again (they used to be a [[ProudScholarRaceGuy race of scholars]]). A later-season episode reveals that they have destroyed at least one other civilization ([[spoiler:that of Nostradamus]]).
* ''Series/TheInvaders'' (1967) with Roy Thinnes as a man who accidentally sees a flying saucer land and can't convince people that we've been invaded. They use the infiltration method, altering their bodies to look like humans. Because of the year there was a lot of heavy handed storylines involving race and the youth culture.
* ''Series/{{Invasion}}'' : A 2005 ABC show is a bizarre case of the infiltration type in which the main aliens are seen only as glowing orange lights in the water, but the infiltrating "hybrids" have the [[EvilTwin exact appearances]] (sans scars or other non-genetic marks) ''[[GeneticMemory and memories]]'' of the dead humans they [[CloningBlues replace]]. This makes (most of) them ''[[TomatoInTheMirror unaware]]'' that they are are infiltrating aliens. It was cancelled after one season, so the actual goals of the invaders are never made clear.
* ''Series/TheOuterLimits1995'': The episode "Dead Man's Switch" dealt with a group of people locked in bunkers completely unaware of what was happening in the world. The last thing they heard was that a fleet of alien ships was heading for Earth with suspicions that they were here to colonize. The episode ends with only one of these people alive, as he is preparing to be rescued, unaware that the invasion has already succeeded.
* Extremely common as a source of villains in ''Franchise/PowerRangers'' and ''Franchise/SuperSentai''. Always an all out attack, but the aliens never attack anywhere other than where the protagonists live (sometimes handwaved as being because they want to take out the threat first).
* ''Series/StargateSG1'' The protagonists spend all their time trying to stop aliens from ''destroying'' Earth (and the Galaxy in general), only to end up with a Goa'uld infiltration of the NID on their hands. Several characters comment on this, citing the low priority this infiltration has compared to more pressing matters, such as the building of the [=McKay=]-Carter Intergalactic Gatebridge. Several episodes show us alternate universes where the aliens do succeed in taking Earth.
* ''Series/StarTrekTheNextGeneration'' and ''Film/StarTrekFirstContact'' : The Borg invasions of Earth shout-outs to ''Literature/TheWarOfTheWorlds'' (e.g. one of the ships fighting the Borg is named ''Thunder Child'').
* The BBC series based on ''Series/TheTripods'' book trilogy. The aliens utilize mind control for their infiltration and subsequent invasion.
* ''Series/TheTwilightZone1959'' had the episode "[[Recap/TheTwilightZoneS2E51TheInvaders The Invaders]]" where AgnesMoorehead (Endora from ''Series/{{Bewitched}}'') was fighting off an invader that was about as big as a mouse. The TwistEnding was that [[spoiler:the "invader" was a US Air Force pilot from Earth]].
* ''Franchise/UltraSeries'' practically runs on a combination of this trope and {{Kaiju}} (often [[AliensAndMonsters with overlap]] as many of the aliens can become {{kaiju}}-sized to battle Ultraman or command kaiju). ''Series/UltraSeven'', in particular, had nothing ''but'' alien invaders.
* Season 3 of ''Series/UnderTheDome'' makes it clear that [[spoiler:this is what the Eggs are supposed to accomplish, holding the life force of refugees from a destroyed planet, who are also fleeing their enemies]].
* ''Series/{{V|2009}}'' (and [[Series/{{V1983}} the original]]): is about a VillainWithGoodPublicity form of The Infiltration, with [[ANaziByAnyOtherName familiar overtones]].
* ''Series/WarOfTheWorlds'': A television sequel to the [[Film/TheWarOfTheWorlds1953 1953 film adaptation]] of ''Literature/TheWarOfTheWorlds'' novel, showing heavy influence from ''Invasion of the Body Snatchers''.

* Music/RunningWild's "Iron Heads" from the ''Death Metal'' split-album and ''Masquerade'' is about and alien invasion. While the chorus shows alien invaders in positive light ("They're coming tonight to make the world alright"), the end result is rather bleak ("Ruins are everywhere, the whole world is empty and dead").
* Music/WeirdAlYankovic wrote "Slime Monsters from Outer Space", which is a version 1.
* Music/CreatureFeature's "Look To The Skies" from ''The Greatest Show Unearthed'' details an alien invasion that starts by a meteor falling to earth that goes full ''Film/InvasionOfTheBodySnatchers'' to conquer the world.
* Music/XJapan's original 1994 anime PV for ''Rusty Nail'' centers around fighting an AlienInvasion of the combined types: an infiltration involving a HypnoTrinket, followed on by a full-scale invasion that destroyed the world. Humanity fights back with phallic weapons, the summoning of CrystalDragonJesus, roses, and [[UpToEleven roses as phallic weapons]].

* This is the basic plot of ''Pinball/AttackFromMars'' and its sequel ''Pinball/RevengeFromMars''.
* The final TV Mode in ''Pinball/TheSimpsonsPinballParty'' is this.
* According to the promotional ComicBook for Bally's ''Pinball/SpaceInvaders'', the pinball machines themselves are the alien infiltration force, disguised as addictive games that steal the minds (and quarters) of unsuspecting humans.
* An invasion occurs if you go to Seattle in ''Pinball/RedAndTedsRoadShow''.
* Just like the [[VideoGame/{{Defender}} video game,]] ''Pinball/{{Defender}}'' pits the player against aliens kidnapping helpless humanoids.

* Creator/OrsonWelles' famous dramatization of ''Radio/TheWarOfTheWorlds'' as a 1938 HalloweenEpisode of ''Radio/TheMercuryTheatreOnTheAir'', which changed the setting to contemporary New Jersey and incorporated a PhonyNewscast for the first portion of the story.

[[folder:Tabletop Games]]
* In ''TabletopGame/DamnationDecade'', the Dervos came to investigate Earth when they detected the Omega Blast and found it an ideal world for farming their vital narcotic Gank.
* No prize for guessing what the old ''TabletopGame/HeroSystem'' supplement ''Invasion: Target Earth'' was all about. It even discusses both styles of invasion and analyzes some of their most common narrative elements. (The sample "invasion" campaigns themselves are then sadly a bit less impressive, most likely due to lack of space.)
* ''TabletopGame/{{Monsterpocalypse}}'' has two extra-terrestrial factions, both launching All-Out Attacks ''at the same time''. The Martian Menace uses {{Tripod|Terror}}s and {{Flying Saucer}}s whereas the Planet Eaters use {{Kaiju}} and a HordeOfAlienLocusts.
* Happens quite often in ''TabletopGame/{{Warhammer 40000}}'', obviously. Said aliens include [[OurOrcsAreDifferent brutish, fight-happy green-skinned barbarians who vaguely resemble English football hooligans]], [[OurElvesAreBetter hyper-advanced space elves with psychic powers]], [[TheFairFolk the evil rape-happy space pirate cousins of said space elves]], [[TheGreys vaguely-East Asian grey skins with mecha]], [[RobotWar death-ray armed genocidal killbots]], and [[HordeOfAlienLocusts a gigantic horde of galaxy-consuming bugs from across the universe]]. They usually come in the form of All-Out Attack, but [[FaceFullOfAlienWingWong for the last one, they sometimes infiltrate]].
** As a mild excuse for the Imperium's AbsoluteXenophobe policies, quite a lot of isolated and defenseless colonies, including ones within the Solar system, were invaded by either some of the guys mentioned above or worse during the Long Night.
** And then inverted during the Great Crusade, where alien worlds frequently found themselves invaded by humans, often with the {{Space Marine}}s as the tip of the spear. [[FinalSolution Most of the alien races invaded in this way don't appear on the 40K tabletop]], whether or not they actually ever engaged in anti-human hostilities.
** The grey-skinned aliens with mecha sometimes use a side strategy where ''they'' don't infiltrate (they're not shape-shifters and are clearly not human), but use a mixture of trade, negotiation, and occasional infiltration by allied humans to bring worlds into their empire relatively peacefully (no sense shooting up the real estate if you don't have to). Depending on how badly the world they're visiting is being exploited by the Imperium, it may qualify as a BenevolentAlienInvasion.
* The point of the [[http://yugioh.wikia.com/wiki/Alien Alien]] monsters in the ''[[Tabletopgame/YuGiOh Yu-Gi-Oh!]]'' card game.
* ''The End of the World: Alien Invasion'' by Creator/FantasyFlightGames offers a few different flavors of this as part of the backdrop for a SurvivalHorror tabletop experience.
* The Mind Dune of the Moon in ''TabletopGame/RocketAge'' is actually an ancient colonisation effort. The aliens were shrunk down into sand-like particles for transport to Earth, but they hit the moon instead of the shallow sea they were aiming for. Now they are attempting an invasion to return themselves to their natural state.
* The Alien faction appear to be pulling this in ''TabletopGame/SmashUp''. How direct their strategy is will vary by which faction they're paired with: one like Ninjas is presumably more focused on infiltration, while Dinosaurs are [[TheBigGuy a bit more direct]].

[[folder:Video Games]]
* ''VideoGame/{{Achron}}'': The game starts immediately after the greatest space fleet humanity has ever assembled has been all but completely destroyed by the alien invaders. They did this despite actually being outnumbered and outgunned by the human forces. It turns out that TimeTravel actually gives you a hell of an advantage.
* In ''VideoGame/ArtemisSpaceshipBridgeSimulator'' you defend a sector of space from an alien invasion.
* ''VideoGame/CityOfHeroes'': Takes place in the aftermath of an extra dimensional alien invasion, which was hard-won and remnants of the Rikti forces still infest the world. [[spoiler: And of course, it turns out that the Rikti are mutated humans. BUT, that leads into another possible future invasion by different aliens.]] The Rikti's weakness? ''Magic''. The Shiva in Bloody Bay are the remains of a [[PlanetEater planet-devouring entity]] that was destroyed in deep space but is now trying to rebuild itself by conquering Earth for its resources.
* An invasion by Lovecraft-inspired aliens is the main conflict in ''VideoGame/CodeNameSTEAM''. To combat it, [[RuleOfCool Abraham Lincoln assembles a team of]] {{Public Domain Character}}s.
* ''VideoGame/CommandAndConquerTiberiumWars'' marks the debut of the Scrin, whose arrival throws the ongoing [[UnitedNationsIsASuperpower GDI]]-[[NGOSuperpower Brotherhood of Nod]] conflict into chaos and force the two sides to [[EnemyMine work together]]. But it's more complicated than an "All-Out Attack" example: the Scrin are trying to harvest the [[GreenRocks Tiberium]] they seeded the Earth with, and expected for the [[AlienKudzu xenoforming crystals]] to have wiped out the planet's indigenous population, but Kane tricked them into arriving early. The Scrin expedition is actually a mining operation, not a formal army, and once they're driven back by the humans they vow to return with a proper invasion force... a SequelHook [[TheyWastedAPerfectlyGoodPlot utterly ignored by]] ''Command & Conquer 4''.
* ''VideoGame/TheConduit'': It starts off with an invasion by the Drudge, a race of BigCreepyCrawlies. Later, [[spoiler:it is revealed that the invaders are actually human-created clones as part of a GovernmentConspiracy.]]
* In ''VideoGame/DestroyAllHumans'', YOU are the invading alien. Crypto utilizes both infiltration and outright military force.
* ''VideoGame/DoctorWho'':
** In the first chapter of the adventure game "[[Recap/DoctorWhoTAGE01CityOfTheDaleks City of the Daleks]]", The Doctor and Amy arrive in London to discover it has been conquered by Daleks and have to travel back in time to stop the invasion.
** The second chapter "[[Recap/DoctorWhoTAGE02BloodOfTheCybermen Blood of the Cybermen]]" has a cybership discovered in the Arctic by a group of scientists. It turns out it crashed there thousands of years ago, and the discovery triggers a reactivation. The Cybermen's goal is to thaw out their army and "upgrade" humanity. Naturally, the Doctor and Amy have something to say about that.
* ''VideoGame/DukeNukem3D'' with an all out assault and in ''VideoGame/DukeNukemForever'' the aliens come back. And they come back angry.
* ''VideoGame/EarthDefenseForce'': The common theme throughout all the games series is that the Ravagers appear and suddenly attack Earth unprovoked.
* ''VideoGame/EccoTheDolphin'': Both game storylines involve aliens. In the first game, the Vortex aliens have been content to just suck up critters from Earth's seas every 500 years, but after Ecco beats them, their Queen follows him back to Earth in the second game, where she and her children proceed to mess everything up. Eventually, she flees back in time to infiltrate Earth from there. WordOfGod has it that [[spoiler:it worked, but not the way she wanted it to; the Vortex lose their identity as a species and give rise to arthropods.]] The third game [[ContinuityReboot involves some completely different]] aliens called the Foe; their time travelling shenanigans actually work to change Earth's future, until Ecco stops them.
* ''VideoGame/EliteBeatAgents'': In the final level, a race of aliens known as the Rhombulans take over Earth and [[CulturePolice outlaw music.]] If anyone is caught singing, dancing, or trying to enjoy music in general, they either get TakenForGranite or sent to what's basically a concentration camp. [[spoiler: But as it turns out, they don't just hate music, music actually ''hurts'' them. [[ThePowerOfRock Which leads to their inevitable downfall as a result of a worldwide rock concert.]]]]
* The first two ''VideoGame/EscapeVelocity'' games featured space combat against alien invaders. In the original, the Confederation [[spoiler:nearly]] wiped them out completely. In ''Override'', the United Earth pushed the Voinians back pretty darn far; the war continues (apparently. There ''is'' a peace treaty, but no one seems to bother about it outside the treaty station of Pax), but has devolved into frequent border skirmishes.
* In the ''VideoGame/ExZeus'' series, the plot of the first installment has Earth retreating underground after an alien race crashes onto the planet and began attacking the human race. To address the alien invasion, the remain government of Earth developed battle robots to fight in a combat operation to back the alien forces and succeeded. It's sequel picks up hundreds of years after the first game with peace restored to Earth only for a new alien threat to emerge. This time they taken the three robots from the first ''[=ExZeus=]'' and combined them into a new battle robot and decided to take the fight into their turf.
* Inverted in ''VideoGame/FTLFasterThanLight'', the premise of which revolves around the [[FantasticRacism human-supremacist]] [[TheRevolutionWillNotBeCivilized Rebel]] fleet trying to destroy TheFederation, which is comprised of other humans and, more importantly, various united alien races.
* In ''[[VideoGame/FeedingFrenzy Feeding Frenzy 2: Shipwreck Showdown]]'', a lugubrious, green alien called the Intruder lurks in the seas, with the intention of colonize the entierity of the Earth oceans. It is up to the local fauna to take this extraterrestrial down.
* A variation in ''VideoGame/{{Freelancer}}'', where it's not Earth that's under threat but the humans living in the Sirius Sector. The aliens are infiltrating the four Houses and are attempting to cripple the human fleets before making their move.
* ''VideoGame/{{Gungrave}}'': A race of parasitic aliens called "Methuselah" came to the planet eons ago and just wanted to infect all living things with the substance that the main characters know as the designer drug called "Seed". It turns humans and animals into mindless mutants subservient to the alien consciousness. It was these beings that manipulated and corrupted Harry in the original game, provided the technology that created the Necrolization Project, and gave Garino, the BigBad of ''Overdose'', power beyond imagination. Garino was even planning to leave the planet to continue spreading seed.
* ''VideoGame/HalfLife1'' is about aliens from Xen coming through a portal to Earth, albeit unintentionally (though given the chance, the Nihilanth was more than happy to conquer, or try it anyway). The second is set in a {{dystopia}} where different aliens, the Combine, came through and defeated both the Xenians and Earth in a CurbStompBattle.
* ''Franchise/{{Halo}}'': The Covenant have a mission to wipe out every human world they can find. In order to ''prevent'' as many alien invasions as possible, humanity enacts "The Cole Protocol"; any human ship that is about to fall to the Covenant is required to wipe its memory banks and ''self-destruct'', denying the aliens knowledge of human colony locations, as well as of Earth itself. In the end, the Covenant find Earth anyway [[spoiler:(though they were looking for something else)]], but this particular strategy allowed humanity to hold out for almost three decades, when otherwise they would have been defeated in weeks or months.
* This is ''VideoGame/HelloKittyRollerRescue'''s plot. Following his last, disastrous attempt at conquering a planet, the evil Emperor Block-O stumbles upon Earth and decides that this time, he will succeed.
* ''VideoGame/{{Iji}}'' Starts six months after the ''almost'' all-out attack has succeeded. Then looms the danger of a ''really'' [[EarthShatteringKaboom all-out attack.]]
* ''VideoGame/{{Insaniquarium}}'' features an alien invasion... of the planet's '''aquariums'''.
* ''VideoGame/InvasionTheAbductors'' is a light gun rail shooter that revolves around saving the Earth from an invasion.
* One of the [[SelfImposedChallenge special challenge paths]] you can play in ''VideoGame/KingdomOfLoathing'' involves an invasion of super-intelligent bugbears from outer space.
* ''Franchise/{{Kirby}}'':
** The [[VideoGame/KirbysDreamLand2 Dark]] [[VideoGame/KirbysDreamLand3 Matter]] [[VideoGame/Kirby64TheCrystalShards trilogy]] consists of extraterrastial one-eyed beings called Dark Matters attempting to engulf Planet Popstar in darkness, they are sent by their boss Zero, a giant, white, red-eyed ball.
** ''VideoGame/KirbyPlanetRobobot'' features different invaders called the Haltmann Works Company, they seek to mechanize and harvest the planet's energy in order to [[spoiler:reactivate a supercomputer named Star Dream.]]
* ''VideoGame/MarioAndLuigiPartnersInTime'' The main plot has the Mario Bros. [[MyFutureSelfAndMe team up with their infant selves]] to thwart the invasion of the alien Shroobs.
* ''Franchise/MassEffect'': The Reapers, the ManBehindTheMan in the first two games, directly assault Earth (having already gone through the batarians) in a massed invasion in the opening of ''VideoGame/MassEffect3''. Next on their list are the turians, and the krogan, and so on.
* ''VideoGame/MegaManStarForce'': In the story, alien life forms, called [[EnergyBeing FM-ians]], must fuse with humans who are very lonely through manipulation in order to attack other people. This is because being energy waves they have no physical form and thus can't harm physical beings under normal circumstances. They can't even be ''seen'' normally. Fusing with humans allows the FM-ian to materialize and thus cause physical harm. They can also disrupt electronic devices or if there is enough electromagnetic energy being emitted, turn people ''into'' energy waves to attack them. KidHero Geo Stelar and a renegade FM-ian, Omega-Xis, merge into Mega Man to defend the Earth from the FM-ians who, in turn, attempt to draw the pair out in order to defeat them and reclaim an item Omega-Xis has to unleash their DoomsDayDevice on Earth.
* ''VideoGame/MetalSlug 2'': The Mars People arrive ''Literature/TheWarOfTheWorlds'' style aliens who attack using flying saucers. When they're driven off, one of them impersonates Morden and tries to use the Rebellion Army as a weapon in ''Metal Slug 3''. Once that's uncovered, the heroes attack their mothership and destroy their leader, Rootmars. Properly chastised, the Mars People become a bit more peaceful, and serve as allies in the sixth game to fight an invasion from BeneathTheEarth that considers them snack food.
* The Kreegans of ''VideoGame/MightAndMagic'' and ''VideoGame/HeroesOfMightAndMagic'' turn out to be this. The twist is that it looks like a ''[[TheLegionsOfHell Demonic]]'' Invasion to most natives (the Kreegan look similar to the actual demons of the setting, and they are unambigiously evil), to the point that ''Heroes'' only presents a slight hint that there's something else going on.
* Eons before the beginning of ''Videogame/NierAutomata'', an alien invasion drove what was left of humanity to the Moon. Since then, humanity's android soldiers have been fighting against the alien's own machines to retake the Earth. [[spoiler:As it turns out, not only had humanity already gone extinct years before the aliens first arrived, but the aliens themselves were annihilated by their own machines centuries ago.]]
* One of the main threats for the mankind and player in ''VideoGame/DieReiseInsAll'' is one from martians. [[spoiler: No big surprise, if you know [[Literature/TheWarOfTheWorlds is what it is influenced by]].]]
* In ''VideoGame/SaintsRowIV'', the plot revolves around the Zin invading Earth, and it's up to the Saints to kill them and save Steelport and Earth altogether.
* Franchise/SonicTheHedgehog and his allies have dealt with a few:
** The Black Arms invade in ''VideoGame/ShadowTheHedgehog'', though the all-out assault on Earth had been planned out at least fifty years prior. The purpose, however, is not so much to conquer or destroy as it is to obtain the Chaos Emeralds.
** The Marauders in ''VideoGame/SonicChronicles'', though not strictly aliens, do arrive en masse from an alternate dimension, and their attempt to conquer Earth plays out very much like one.
** The Zeti attempt an invasion in ''VideoGame/SonicLostWorld'', though the invasion force consists of only six members. They each can psychically hijack an unlimited number of machines to do whatever they want, making them a major threat anyway. Sonic immediately takes the fight over to their planet, the Lost Hex, and stops them before they can do any significant damage.
** [[InvertedTrope Inverted]] in ''VideoGame/SonicTheHedgehogCD'': Dr. Eggman and his robot army invade the Little Planet in order to take it over. Eggman succeeds, covering the planet in a metallic shell, requiring Sonic to travel to the past.
* ''VideoGame/SpaceInvaders'', of course. The Invaders use the all-out attack approach. [[FridgeLogic And they always win.]]
* ''VideoGame/StarCraft'': the Terrans are facing two invasions: the [[BugWar Zerg]] and [[WellIntentionedExtremist Protoss]]. The Zerg favor infiltration [[BodyHorror infestation]] as a way to soften up targets for the Swarm. The Protoss, on the other hand, employ a range of tactics, from "shoot missiles at it" through "shoot [[MacrossMissileMassacre more missiles at it]]" past "[[BeamSpam throw in lasers]] for good measure" and on to "screw it, let's just [[ApocalypseHow sterilize the planet]]". Notable in all of this is the Battle of Tarsonis, where the Zerg, Protoss, and [[LaResistance Terran rebels]] all try the All-Out Attack on the poor planet [[ClimacticBattleResurrection at the same time]]. The Protoss were not as much invading the Terrans as they were containing the Zerg who would then perform an all out invasion on the Protoss.
* Inverted in ''VideoGame/{{Stellaris}}'', your empire, or AI empires for that matter, can invade pre-FTL species through either an all-out assault or infiltration. The primitives can sometimes thwart the latter, the former, [[OrbitalBombardment not so much]].
* ''VideoGame/SuperMarioFusionRevival'' has Martians invade World 2, which is based on our Earth (with a good helping of ''VideoGame/MetalSlug'' thrown in). In World 6, the Covenant and other alien forces are making war with each other.
* Inverted in ''[[VideoGame/ToejamAndEarl ToeJam & Earl: Panic on Funkotron]]''. The aliens on the planet of Funkotron are fending off an Earthling invasion.
* In the ''VideoGame/UFOAfterBlank'' series, the aliens are launching all-out attacks. Unlike many examples, the first invasion was not only successful, but [[CurbstompBattle devastatingly so]], and the human resistance is made up of the survivors of the initial invasion. In addition, the first invasion force, made up of the [[TheGreys Reticulans]], is actually a small renegade force from their main, benevolent empire who have limited resources, which is the only reason you're able to hold your own against them at first. The subsequent alien invasions in the later games have their own reasons for being limited in overall force. Ultimately, it turns out that [[spoiler: all of the alien invaders from the first two games are subsets of larger civilizations, and have been mind-controlled by ''another'' alien force that are engaging in a massive interstellar mating ritual in which the "males" take over civilizations and have them fight to prove themselves worthy to mate with a female, which the first Reticulan invaders brought to Earth.]]
* ''VideoGame/UniverseAtWar: Earth Assault'': An all out attack, In a subversion, humanity fails utterly at repelling the invading Hierarchy and are reduced to bit players, forced to watch as a race of mechanical {{Laser Guided Tykebomb}}s arrive on Earth and the [[AncientAstronauts ancient Atlanteans]] awake, both species intent on bloody revenge against the Hierarchy for crimes committed against them in the past.
* ''Franchise/{{Warcraft}}'':
** The [[TheLegionsOfHell Burning Legion]] manages to be a demonic invasion and this trope at the same time. Most demons in the ''Warcraft'' universe are born from the Twisting Nether, the series' demonic realm that connects to all worlds. However, a good number of the Legion's ranks, such as the Eredar, were originally races from various planets who were corrupted with [[TheCorruption fel energy]] and then recruited by the demons. The Old Gods are a similar case, being horrific [[PlanetaryParasite Planetary Parasites]] created by extradimensional [[CosmicHorrorStory Lovecraftian beings]], sent to infest Azeroth long ago.
** The First and Second Wars can also be seen as this, as Orcs are not native to Azeroth, having come through the Dark Portal from Draenor. They were meant to be the vanguard for the Burning Legion, but failed when the Alliance defeated them in the Second War.
* ''VideoGame/WonderlandAdventures: Planet of the Z-Bots'' is about the invasion of alien Z-Bots.
* ''VideoGame/XCom'': The various aliens in the game series are generally set on utterly destroying humanity. The infiltration method they attempt in the first game was merely a tactic toward the goal of total destruction.
** ''X-COM: Interceptor'' is an inversion, of sorts, as it's the ''humans'' who are trying to muscle in on the aliens' turf.
** ''VideoGame/XCOMEnemyUnknown'' (2012) changes things up a bit. The aliens are still invading, but world domination or the extinction of humanity are not their goals this time around. [[spoiler: They're actually ''testing'' humanity to see if we can A) survive their limited but devastating onslaught and B) see if we can develop PsychicPowers, and thus join the Ethereals as equals.]] The sequel ''VideoGame/{{XCOM 2}}'' occupies an AlternateContinuity from the first game's good ending and assumes that the player failed (badly too). Earth is now firmly in alien hands, and what remains of XCOM is now LaResistance, attempting to get the remaining population of Earth to rise up.
** And the theme returns in the ''X-COM'' series' Main/SpiritualSuccessor, ''VideoGame/{{Xenonauts}}''. The game even comes up with a plausible new reason for the escalation. It turns out that the alien ships are not designed for atmospheric flight, much less [[OldSchoolDogfight old-school dogfights]], but the aliens are slowly modifying their craft with the smallest craft modified faster.
** ''VideoGame/TheBureauXCOMDeclassified'' (which occupies an AlternateContinuity, despite being touted as a prequel), has the aliens as PlanetLooters who need to constantly take other planets, as they quickly use up any planet under their rule. Any new race is added to [[HiveMind Mozaic]] to be used as soldiers for the next invasion.

[[folder:Web Comics]]
* The Earth of ''Webcomic/DeviantUniverse'' has had two of them, [[spoiler: led by the same individual.]]
* ''Roleplay/EnemyQuest'': The Visitors invaded earth from [[AnotherDimension another dimension]] and started slaughtering humanity. [[spoiler:Internal strife and growing sympathy for the humans led to a truce.]]
* In ''Webcomic/{{Galaxion}}'' 76432-69-GM has been infiltrated by {{Puppeteer Parasite}}s [[AfterTheEnd a while ago]].
* The webcomic ''Webcomic/{{Hexenringe}}'' [[http://hexenringe.blogspot.jp/2013/10/001-prologue-1.html starts with]] a meteor crashing to Earth from which an alien {{Kaiju}} emerges. Soon after [[spoiler: A very hip {{HenshinHero}}]] who is also an alien [[spoiler: arrives to save the day.]]
* ''Webcomic/TheInexplicableAdventuresOfBob'': Subverted, where the Nemesites have legally owned Earth since before mankind even evolved. Until we develop good enough technology to leave Earth, they don't particularly ''care'' whether or not we know they own the planet. SpacePirates do attack Earth once, not to conquer it but to randomly steal stuff. Nemesite Princess Voluptua comes to stop them, informing them, "Earth is a ''nature preserve,'' you feebs! This isn't even piracy--It's ''poaching!"''
* ''Webcomic/{{Titanzer}}'': They not only invaded but [[http://titanzer.com/new-readers/ punched the head off the statue of liberty]].

[[folder:Web Original]]
* Several on John Dredge's [[Podcast/TheJohnDredgeNothingToDoWithAnythingShow various programmes]]:
** On ''The Daily Dredge'', the Prunes from Omicron 3 want to invade earth, but have to phone in and ask for the way:
--->'''Listener:''' ''[calling in]'' Yeah, they need to take the A14. That'll take them directly from Omicron 3 to Prestwood Town Centre.
** In a later episode, ''The Human League'' has to prevent a race of evil aliens from stealing all the synthesisers in the world:
--->'''Phil Oakey:''' But don't they have / any synthesisers of their own?\\
'''Secret Service Head:''' Their synth pop technology is way behind ours. They've only just mastered the [=LinnDrum=].
** And finally, on the ''Nothing to Do with Anything Show'' itself, there's the ongoing series of ''The Aliens That Came from a Completely Different Planet to Earth''.
* In ''Literature/TheLastAngel'', this is how the compact grows. Standard first contact protocol is to jump a fleet in above an enemy world and ask it to join. If they decline, the fleet starts shooting until they say yes.
* ''Wiki/SCPFoundation'', [[http://www.scp-wiki.net/scp-2069 SCP-2069 ("AEGIS")]]. SCP-2069 is the debris that washed up on the shore of Australia after falling into the Foundation's Earth through a transdimensional breach. In an AlternateUniverse, an alien space fleet attacked the Earth and destroyed all major cities, then invaded. The Foundation and the Global Occult Coalition teamed up (calling themselves "AEGIS") to fight them, and ultimately deployed a weapon of mass destruction that caused the breach.
* ''WebAnimation/SuperMarioBrosHeroesOfTheStars: The main plot is the Shroobs invading.

[[folder:Western Animation]]
* ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'': Three separate times. [[WesternAnimation/JimmyNeutronBoyGenius The first time the Yolkians arrived to Earth]] they stole every adult in Retroville (except Miss Fowl) only to take them to their planet in order to feed them to their giant chicken god. The second time they arrived on Earth they successfully earned everyone's trust and tried to kill off all the adults once more. Then there is Grandma Taters, who's apparently one of many similar aliens that take over planets using hypnosis.
* ''WesternAnimation/Ben10AlienForce'''s first season finale climaxed with the Highbreeds beginning their planned invasion of Earth. Oddly enough, they aren't so much as fought off as [[spoiler: convinced to stop when the heroes learn their invading due to being a DyingRace whose genetics won't let them repopulate. It isn't until Ben uses the Omnitrix to mix various alien species with their own, saving them, that they call off their attack.]]
* ''WesternAnimation/BumpInTheNight'' featured a pair of aliens named Sleemoth and Gloog as minor antagonists, whose attempts at conquering Earth were always thwarted by Mr. Bumpy, Squishington, and Molly Coddle thanks to the aliens being highly arrogant and gravely underestimating our heroes.
* ''WesternAnimation/{{Futurama}}'':
** Happens from time to time. To paraphrase a ''Futurama'' comic:
--->'''Fry:''' So what, Earth gets invaded twice a week. It's how I remember to brush my teeth.
** The professor actually looks forward to them. According to him, the last invaders made all the smartest humans "[[GeniusBreedingAct pair off and mate continuously]]... [[AnticipatoryBreathSpray oh yes.]]"
* ''WesternAnimation/InvaderZim'': The show is about an alien using the third method. [[ChaoticStupid He's really bad at it]]. However the Irkens are really good at what they're doing, no matter how bad Zim is. We've seen them successfully take over several planets and they seem to run a galactic monopoly that can't be challenged by any other being in the Universe (to our knowledge).
* ''WesternAnimation/JusticeLeague'' and ''Justice League Unlimited'':
** The very first story arc, "Secret Origins", sees the Justice League come together for the first time to combat shapeshifting aliens. Initially, the aliens infiltrate society to undermine Earth's defense systems, then they begin their All-Out Attack. The Good Alien role is filled by [[ComicBook/MartianManhunter J'onn J'onnz]], the [[LastOfHisKind sole survivor]] of a Martian civilization that these invaders had destroyed centuries ago.
** The Season Two GrandFinale "Starcrossed" sees the League nearly destroyed by another invasion. The [[spoiler:Thanagarian]] infiltration was far more effective, because they had a [[TheMole Mole]] in the Justice League itself, providing them with the information to neutralize its members. These invaders initially present themselves as the Good Aliens, claiming that they're fortifying Earth to defend it from their enemies; the ''real'' Good Alien turns out to be their Mole, [[spoiler:Hawkgirl,]] who learns of their true intentions for Earth and is [[BecomingTheMask unable to go through with it]].
** The ''JLU'' episode "Dark Heart", in which the League faces Grey Goo from outer space.
** The ''JLU'' GrandFinale "Destroyer" has Darkseid leading the forces of Apokolips on an All-Out Attack on Earth. The League is forced to [[StrangeBedfellows temporarily team up]] with the remaining members of the Legion of Doom in order to fight them off.
* ''WesternAnimation/KimPossible'': The GrandFinale had the previously once introduced ScaryDogmaticAliens invade Earth for rather no real reason at all. All they did was send in {{Humongous Mecha}}s while the two aliens just sat and relaxed. Rather than an "official" government-backed invasion, it appears that the whole attack was simply a private vendetta against Drakken/Earth on the part of Warmonga.
* ''WesternAnimation/LittleAudrey'' cartoon "Dizzy Dishes": In Audrey's dream there are alien invaders attacking with a disintegrator.
* A recurring theme in ''WesternAnimation/MenInBlack'', very often the MonsterOfTheWeek is an alien invading force including some recurrent villains like the [[LilliputianWarriors Fmeks]] and the [[PlanetLooters Blastula]].
* ''WesternAnimation/OhNoItsAnAlienInvasion'' is about a group of kids dealing with, well, [[ExactlyWhatItSaysOnTheTin an alien invasion]] that has abducted all of the grown-ups.
* The ''WesternAnimation/ThePowerpuffGirls'' episode "Beat Your Greens" featured the Broccoloids, alien invaders who happen to be broccoli. [[spoiler: The Girls and the kids of Townsville unite to stop the Broccoloids... by EATING them.]]
* ''WesternAnimation/TheSimpsons'' did this many times with Kang and Kodos. The best was prior to the 1996 presidential election where they kidnap Clinton and Dole and take their places (infiltration method). In the end they are discovered but still win because they have both major candidates and "It's a two party system. You have to vote for one of us." Someone suggests voting for a third party candidate: Alien: Sure, THROW your vote away!" In the end they are our rulers.
* The backstory of ''WesternAnimation/StevenUniverse''. Far from being magical protectors, it turns out that Gems are actually StarfishAliens who arrived on Earth thousands and thousands of years ago to drain its resources, even if it would kill all life living there. The Crystal Gems are the only survivors of a [[MySpeciesDothProtestTooMuch rebellion]]. Then [[spoiler:the Homeworld Gems start returning to finish the job...]]
* ''WesternAnimation/TeenageMutantNinjaTurtles2003'' : There was a 3-part episode "Space Invaders", which centered on the Triceratons invading Earth in their frantic search for the Fugitoid.
* ''WesternAnimation/TeenTitans'': In the episode "Troq". [[InvertedTrope Gets inverted]] The Titans launch a preemptive attack against the [[WhatMeasureIsANonHuman robotic, alien]] menace on their own, alien planet. Our heroes succeed in killing the entire planets’ population off! Then they tell off the guy who brought them there for being a [[FantasticRacism racist douche]].
* ''WesternAnimation/ThunderCats2011'' episode "Journey to the Tower of Omens": a massive invading army [[WeWillUseManualLaborInTheFuture comprised]] of multiple {{Slave Race}}s housed in a giant [[TheBattlestar Battlestar]] are depicted invading an unidentified planet to serve as PlanetLooters, combing over land and sea in seach of a single, extremely valuable AmuletOfConcentratedAwesome called the War Stone, by order of their commander.

* The original ''Film/MarsAttacks'' trading cards shows the Martians invading Earth and committing all sorts of war crimes for the fun of it, so the audience won't feel sorry for them when the trope is later [[InvertedTrope inverted]] and the humans [[GuiltFreeExterminationWar invade and destroy Mars]].
