->''"Okay, that's it. It's official: All aliens are bastards!"''
-->-- '''[[VideoGame/HalfLife Gordon Freeman]]''', ''Machinima/FreemansMind''

When man looks up at the stars, the sense of wonder, and emptiness, can be as overwhelming as the questions they inspire. Is there life out there? Is it intelligent? Are they friendly? In fiction, the short answers are: "Yes", "Yes" and "''Hell no!''" Why? Because Aliens Are Bastards.

In SpeculativeFiction stories dealing with the extraterrestrial and otherworldly, the beings from beyond the veil are rarely friendly, and if they are it's usually a pretense so they can [[ToServeMan eat us]] or [[FaceFullOfAlienWingWong make us mommies]] less than consensually. The reason is that it makes good drama, [[CosmicHorrorStory it exploits humanity's latent fear of the unknown with implacable and indecipherable menaces]]. Traditionally this trope uses aliens not as characters but as forces of nature. They will be the MonsterOfTheWeek for the heroes to fight, a terrifying and nigh-unstoppable foe with little to no motivation other than violence for its own sake.

This type of alien bastard is usually very visually distinct from [[AlwaysLawfulGood "good" aliens]] ([[BeautyEqualsGoodness who tend to be]] {{Green Skinned Space Babe}}s). They will be [[WhatMeasureIsANonCute ugly]], obviously [[WhatMeasureIsANonHuman inhuman]] and rarely [[WhatMeasureIsAHumanoid humanoid]]. Of course, they [[WeComeInPeaceShootToKill won't be friendly]], [[WhatIsThisThingYouCallLove do not understand love]], want to [[MarsNeedsWomen steal our women]], [[PlanetLooters natural resources]] and possibly leave [[EarthShatteringKaboom nothing behind of the planet itself]]. Despite having the technology needed for space travel, they will make no attempt to communicate or explain their actions and seem to have targeted us for [[JustForFun/WhyYouShouldDestroyThePlanetEarth no good or readily apparent reason]].

This is aliens being AlwaysChaoticEvil. If they are {{Precursors}}, they were either {{neglectful|Precursors}} or are [[AbusivePrecursors downright abusive]].

On a lesser scale, there are, of course, TheGreys with the reputed stereotype of [[AliensStealCattle mutilating cattle]] and [[AlienAbduction abducting humans]] for the sole sake of [[AnalProbing probing]] them [[ForScience in the name of Science]] for their own, vague, nefarious purposes.

When the aliens' motivations for bastardry are placed parallel to humanity's negative traits, revealing the two to be NotSoDifferent, then HumansAreTheRealMonsters.

When the aliens are used as allegories for a certain ideal, organization or country that the writer doesn't like, then they're ScaryDogmaticAliens. As with the above, the negative traits of the targeted group are almost always excessively exaggerated. Expect the aliens to display traits displayed by said group's VocalMinority, with the implication being that the ''entire group'' is as crazy and violent as the aforementioned minority. The similarities with JerkassGods, especially when the aliens are god''like'' in power, may not be coincidental.

Something of a DiscreditedTrope, as the depiction of aliens as mindless beasts or imperialists bastards has generally fallen out of use in favor of more civilized beings who can discuss [[ArmorPiercingQuestion the finer points of philosophy]] and provide a convenient canvass for the writer to [[AnAesop paint his or her message onto.]]

'''NOTE: This trope does not apply to animalistic aliens without intellect. Violent as they are, they aren't ''knowingly'' being bastards.'''

----
!!Examples:

[[foldercontrol]]

[[folder:Anime & Manga]]
* ''Franchise/DragonBall'' has many races in its universe and only a small percentage are actually good. Most are [[JerkAss assholes]] who either HeelFaceTurn or die a KarmicDeath; [[EvilOverlord Frieza]] is the most blatant of these characters.
* ''Manga/HoushinEngi'' has [[spoiler:Jyoka. She has been playing God with this little planet of ours for ''millions'' of years,modifying genomes of species,altering face of the world,causing rise and fall of major dynasties and in short controlling the history of the entire planet in order to evolve it into a perfect replica of her lost home planet. When something goes wrong in her plan,she life wipes the entire planet,destroying the planet's surface and starts afresh.She has repeated this rinse and repeat tactics quite a few times,by the time the story begins.Oh,and she does all this in spirit form,cut off from her physical body and much of her power!]]
* In ''LightNovel/HaruhiSuzumiya'', it is eventually revealed that both the Data Integration Thought Entity and the Sky Canopy Dominion, the two opposing races of SufficientlyAdvancedAlien, are too concerned with fighting each other than caring about the effect their actions will have on humans, or even their own interfaces. Indeed, [[spoiler:The DITE is willing to send Yuki as an ambassador to the [[EldritchAbomination Dominion]], in order to [[BreakTheCutie break her]], as punishment for going rogue due to an error which wasn't her fault in the first place. The only reason they can't enforce a more direct punishment is because [[BadassNormal Kyon]] is threatening them with a [[TrustPassword trump card]] that could potentially fuck over the universe.]] The Sky Canopy are the villains, so they're even worse than that. When Kyon tells another DITE Interface that "Earth is not a playground for aliens", the response is, roughly, [[CosmicHorrorStory "What an entertaining joke."]] So at this point, it seems that the only unambiguously good alien is [[MySpeciesDothProtestTooMuch Yuki]].
* The aliens in ''Anime/SeikimatsuOccultGakuin''.
* ''Anime/UFORoboGrendizer'' plays with this trope: At the start [[Anime/MazingerZ Kouji]] believes he can try to communicate with the Vegans -the alien invaders- and befriend them, but [[TheHero Daisuke]] tries to warn him they are NOT his friends and are NOT peaceful or reasonable. However, Daisuke himself was an alien and a decent person. And although the BigBad, Great King Vega and several of his subordinates are definitely evil, throughout the series more aliens -including Vegans- are introduced are decent people or at the worst are [[WellIntentionedExtremist Well-Intentioned Extremists]] who believe UtopiaJustifiesTheMeans.
** This approach on alien morality is common within many other SuperRobotGenre series of ''Grendizer'''s ilk. The Anime/RobotRomanceTrilogy especially comes to mind.
* One of the most twisted examples of this trope is the [[spoiler: Anti-Spiral]] of ''Anime/TengenToppaGurrenLagann''. Ostensibly, he's a WellIntentionedExtremist who's trying to prevent the death of the universe. That's a noble goal, right? ''WRONG!'' The way he goes about preserving the universe involves MindRape to send entire races past the DespairEventHorizon, [[OmnicidalManiac attempted omnicide]] and [[MoralEventHorizon torturing]] TheWoobie. And he enjoys seeing other species cross the DespairEventHorizon. His VillainousBreakdown at the end reveals that a good chunk of this is simple envy of the other races who haven't sacrificed their Spiral power.
[[/folder]]

[[folder:Comics]]
* In the ''ComicBook/TwoThousandAD'' strip, ''Bec & Kawl'', TheGreys who abduct Pierre seem to view humans as play-things to be abused and toyed with for their amusement, at least when not partaking in the traditional AnalProbing and [[HalfHumanHybrid alien-human hybrid]] experiments. When The Greys decide to recruit Pierre (who is a pest control expert) for the job of "taking on the filthiest vermin of all" (a separate malevolent alien race hiding amongst us on Earth, waiting for the opportune moment to strike), it turns out to be [[spoiler:a BatmanGambit for The Greys' own benefit of helping them conquer Earth themselves.]]
* Pick an alien race from Creator/MarvelComics. Any of them will do:
** [[SecretInvasion The Skrulls]] like to infiltrate other planets with their [[VoluntaryShapeShifting shape-shifting power]] in order to destroy them from the inside. This is usually because they're ([[{{Irony}} ironically enough]]) just that damn paranoid.
** [[ComicBook/TheAvengers The Kree]] like to [[EvilutionaryBiologist play god with genetics]], are big fans of enslavement, and are [[ANaziByAnyOtherName Nazis]] InSpace!
** [[ComicBook/{{X-Men}} The Brood]] are {{exp|y}}ies of the Xenomorphs from the Franchise/{{Alien}} franchise except they are a bit more intelligent, thus giving them no excuse to act like animals.
** ComicBook/{{The|Avengers}} [[ComicBook/{{X-Men}} Shi'ar]] [[ComicBook/FantasticFour Empire]] are probably the "nicest" aliens. They're a militaristic empire that bounce back and forth between [[WellIntentionedExtremist Well Intentioned Extremists]], [[AntiHero Anti-Heroes]], and [[TheSocialDarwinist Social Darwinists]] depending on who is in charge of the empire and what mood they are in. They tend to fight against Earth's heroes as often as they team up with them. They're not above murdering [[ThePurge someone's family]] just because they ''might'' conceivably become a threat someday.
** The aliens in ''GuardiansOfTheGalaxy'' killed Earth's heroes and took over the galaxy for a time as the backstory for the series. Which alien race is responsible depends on the {{retcon}}.
** The symbiotes from ''ComicBook/SpiderMan'' are parasitic organisms that cling to people who are [[AxCrazy violently insane]] and then drive them even more insane before killing them. Spidey's villain, ComicBook/{{Venom}}, has a rare symbiote in that it actually cares for "her" hosts. Yes, that's right. Venom ''is the nicest product of that race''.
** [[http://en.wikipedia.org/wiki/Badoon The Badoon]] not only hate you, but they [[MonsterMisogyny hate women as well]]. They're not above turning your corpse into a cyborg monstrosity, sometimes not [[StrappedToAnOperatingTable even waiting until you're dead]].
** [[RomSpaceKnight The Dire Wraiths]] are related to Skrulls but [[MagicVersusScience use magic instead of technology]].
** [[ComicBook/TheAvengers The Space Phantom]] was the shapeshifting advance scout of a race of aliens from the planet Phantus who wanted to conquer Earth... [[{{Retcon}} that is until Immortus recruited him and revealed his true origin.]]
** [[ComicBook/{{X-Men}} The Phalanx]] combine the [[Series/StarTrekTheNextGeneration Borg]] with a ZombieApocalypse. Fun!
*** The technarchy they come from want to eat everything, [[GoneHorriblyWrong the Phalanx are why they don't play with their food.]] Keeping their numbers low is that technarchy are also bastards to each other.
** There are some races such as the TheInhumans and [[{{Thanos}} Eternals]] who are [[TranshumanAliens more or less aliens but they are also off-shoots of humanity.]] They are usually good guys but they've had their moments (read ''WarOfKings'' to see what the Inhumans have been doing lately). In this way, they combine Aliens Are Bastards with HumansAreTheRealMonsters in one, neat package.
** The [[CrisisCrossover crossover event]] "Maximum Security" debuted with a conference of many different alien races voting on what to do about Earth, since Earthlings were always meddling in their affairs. The only race that spoke up for us were the Kymellians from ''PowerPack,'' who seem to be AlwaysLawfulGood and knew us mostly from their dealings with the friendly Power {{children|AreInnocent}}. And for the record, the decision that was reached at said conference was "impose an inter-species blockade on Earth and use it as a dumping ground for all our worst criminals."
*** And speaking of ''PowerPack'', the Snarks count too. Though apparently not all Kymellians weren't as good as Aelfyre.
** And of course, aliens from AnotherDimension instead of another planet are like that too - Just look at the Negative Zone's [[DimensionLord Blastaar]] and [[OmnicidalManiac Annihilus]], or worse, [[EldritchAbomination Dormammu and Shuma-Gorath.]]
* This is less true over at Creator/DCComics, probably because so many DC alien races first appeared as members of the Comicbook/{{Legion of Super-Heroes}}.
** Prior to the Comicbook/{{New 52}} DC reboot, the most recent depiction of the [[Franchise/{{Superman}} Kryptonians]] cast them in an unflattering light. LackOfEmpathy for anyone that isn't a Kryptonian is their [[PlanetOfHats Hat]].
** The Daxamites' [[PlanetOfHats Hat]] is [[AbsoluteXenophobe vicious xenophobia]]. {{Iron|y}}ically, the Daxamites are taught their entire lives that Aliens Are Bastards, which makes ''them'' bastards when they kill any alien they meet just for existing. Notably, Daxamites are the product of a genetically-diverged Kryptonian LostColony, so at least the genus is consistently xenophobic.
** [[Comicbook/NewGods The people of Apokolips]]. All of them. Even the downtrodden Lowlies prove themselves to be total bastards if they are given power -- {{Darkseid}}'s TortureTechnician Granny Goodness used to be one of the Lowlies. One of Darkseid's hobbies is to free some slaves and make them his new overseers just so he can watch them become as cruel as their former tormentors. Considering [[AGodAmI who's]] [[GodOfEvil in]] [[FisherKing charge]] of the place, being the biggest bastard you can be is actually a ''very'' sound survival strategy.
** The Thanagarians from Comicbook/{{Hawkman}}, Tamaranians from Comicbook/TeenTitans, and the citizens of Rann from AdamStrange have all had turns being antagonists at some point but they tend to be more gray than many of the aliens here.
** The DC crossover ''Comicbook/{{Invasion}}'' involved many races forming an alliance to invade Earth, this included the aforementioned Thanagarians and [[Comicbook/{{Legion of Super-Heroes}} Chameleon Boy's race]]. A race called the Dominators were the main villains, however.
** Coluan scientist and Superman villain {{Brainiac}} has personified this trope since 1958. The Coluans as a whole aren't always evil, but pretty much all of them are jerks. It's an entire planet of [[InsufferableGenius insufferable genuises]], and no, they don't like offworlders.
* The ''MarsAttacks'' series, based on the trading card series from TheSixties (see page image), featured Martians running amok on Earth. This race seemed to be AlwaysChaoticEvil in every version.
** The trading card series ''did'' have a reason for the attack ([[spoiler:Mars will soon blow up, so the Martians need a new home quickly]]), though jumping ''directly'' to a brutal, excessively cruel invasion was kinda bastardly.
* The comic ''Brain Camp'', whose alien birds were collaborating with the leaders of a kids' camp to use the kids as incubators for their young. True the race was dying on its own, but it's still squicky to see aliens bursting out of teenagers.
* The Xorda in ''ComicBook/SonicTheHedgehog'' is this. Granted, they're still sore over having their diplomat captured, killed and dissected by humans, but deciding that Mobians were just the same as the humans they all but wiped out was a little harsh. Most other worlds, such as the Bern, are much more friendlier, but they don't get involved with Mobius because they don't want the Xorda breathing down their necks. Doesn't stop [[VideoGame/ShadowTheHedgehog the Black Arms]] from trying to claim Mobius as their own and getting stuck in a massive war.
* The [[ComicBook/TransformersMoreThanMeetsTheEye Decepticons]], as usual. At one point in their ForeverWar, they started creating their own empire, by wiping out organic civilisations and altering the planet to suit their needs. Their usual tactic consisted of escalating conflicts, letting the locals do most of the damage, then sending in a SuperSoldier to finish the planet off.
[[/folder]]

[[folder: Fan Works]]
* In [[Fanfic/EquestriaAHistoryRevealed Equestria: A History Revealed]], the narrator theorizes that this was the reasoning behind [[spoiler: the birth of Discord]]. Apparently, he was created through an alien [[spoiler: intergalactic space orgy]], which they only did for kicks.
* In ''[[Fanfic/TheLionKingAdventures The Lion King Adventures]]'', the Inque and the Vimelea are vicious alien parasites that take over minds and, in the case of the latter, entire ''souls''. Naturally, they wish to enslave the earth.
* The flipside to [[HumansAreTheRealMonsters the original idea]] of ''Fanfic/TheConversionBureau'': several pro-human spin-offs characterize ponies as xenophobic {{Social Darwinist}}s with KnightTemplar tendencies. In-universe comparisons between Equestria and UsefulNotes/NaziGermany are common.
* In ''Fanfic/WorldwarWarOfEquals'' alien aircraft pilots don't seem to care whether their targets are civilian or military and then [[spoiler: there is the nuking of several highly populated Human cities, killing thousands]].
[[/folder]]

[[folder:Films -- Live Action]]
* ''{{Film/Avatar}}'' by Creator/JamesCameron inverts the trope to make humans the bastard aliens.
** The ''averted'' part comes from the fact that the sentient race which is considered "alien" at first (the Na'Vi) are clearly a good-natured people who are willing to consider any life sacred, and they accepted the humans' presence until the {{Corrupt Corporate Executive}}s decided to destroy their homeland and hire trigger-happy mercenaries to murder the natives for greedy purposes.
** The part ''played straight'' comes from the fact that the humans (particularly the greedy corporation) are the ones invading a foreign planet, destroying the land, and murdering innocent natives, all for a mineral that's worth a lot of money. The protagonist even refers to the invaders as "aliens" by the end of the movie, [[FridgeBrilliance making us realize that we didn't notice the humans' "alien-ness" all along]]. So the movie can be viewed as an Alien-Invasion film from the point of view of the aliens.
* ''Film/TheDayTheEarthStoodStill2008'' has aliens nearly wipe us out because we were potentially about to destroy the environment. In their defense, they were going to negotiate first, but then their envoy was shot and captured, and his request to speak to the UN was denied. [[HumansAreTheRealMonsters None of this went far toward proving that humans were no longer careless, violent, or wasteful]]. [[Film/TheDayTheEarthStoodStill1951 In the original version]] the aliens only come to Earth after Earth developed nuclear [=ICBMs=]... they don't care at all what humans do on their own planet, but the instant they can launch weapons towards other planets they intervene.
* ''Film/MarsAttacks'' parodies the whole thing with TheUnintelligible belligerent Martians.
** Accentuated, if only because all the HumansAreMorons.
* ''Film/IndependenceDay''. And how! They are a race of PlanetLooters who take what they need and wipe out what's left of the planets they ravage.
* ''Film/TheWarOfTheWorlds'' has the Martians attack Earth. The remake shows them using people as compost; for AlienKudzu, in fact.
* Fresh addition: ''Film/{{Skyline}}'''s aliens are complete assholes. Sure they invade the planet, hypnotize people with their blue lights and brutally steal the brains of anyone they capture to use as {{Wetware CPU}}s, but what do they do when they come across ''pregnant women''? They try to suck the babies out of them, that's what.
* The Franchise/{{Predator}}s, who use Earth as a game reserve for HuntingTheMostDangerousGame. The ExpandedUniverse of the ''AlienVsPredator'' comics show they regularly seed other planets with aliens so they'll have a good hunting spot later on.
** Note that this is a major case of DependingOnTheWriter; nobody seems to be able to agree on how good or evil the Predators are. Most try to portray them as extremely honor-bound and having a society built on "the strong led". There's one comic where a Predator comes to Earth not to hunt, but to apprehend a serial killer who has come to Earth for that purpose. There's been multiple times where Predators have acted very respectful of other races (particularly humans) and worked with them to deal with a problem (most commonly dealing with a xenomorph infestation).
* In ''Film/BattleLosAngeles'', within minutes of the first alien craft crashing down in the ocean, they're opening fire on civilians and shooting indiscriminately. Corpses of massacred human civilians and soldiers are visible nearly everywhere throughout the movie, and news reports state that the aliens are rounding up humans with death squads and executing them in the streets. One scientist suggests that the aliens are using textbook "colonization" tactics: invade, wipe out the indigenous population, and take their resources.
** [[spoiler: Possibly subverted, since there's an implication that ''extreme'' ValuesDissonance is going on between the humans and aliens.]]
* ''Film/CowboysAndAliens'' featured a race of alien miners who make it a point to capture and dissect humans out of curiosity.
* In ''Film/{{Prometheus}}'', [[spoiler:while an Engineer did seed life on Earth, at some point in history the other Engineers decided humanity needed to die. Extinction was averted when the Engineer ship sent to destroy humanity fell prey to the Engineers' own bioweapon. The lone surviving Engineer tries to complete the mission moments after being woken up by the Prometheus' crew. WordOfGod confirms that the Engineers by and large are monsters. The fact that they created a horrific mutagenic bioweapon -- the Xenomorphs being a mere ''by-product'' of it -- capable of wiping out all life on a planet also doesn't paint them in a good light.]]
* In ''Film/PacificRim'', it's initially assumed that the {{Kaiju}} are just enormous animals who are attacking from predatory instinct. However, the scientist Newt accesses kaiju memories at one point and discovers [[spoiler:they're bioweapons being created by aliens to wipe out humans, because they intend to colonize Earth to drain it of its resources like they've done to so many other worlds.]]
* In ''Film/{{Impostor}}'', the Alpha Centauri aliens attacked humanity and try to destroy Earth civilization for no apparent reason, as their motives aren't revealed in the film.
* ''Franchise/{{Godzilla}}'' takes this trope and runs with it. While some of the earthborn {{kaiju}} eventually reform, the alien ones have all remained evil to the end. Whether they are {{cosmic horror}}s like [[AnimalisticAbomination Ghidorah]], AxeCrazy lunatics like [[PsychoForHire Gigan]], or would-be conquerors like [[EvilTwin [=SpaceGodzilla=]]], they've all been bent on killing as many people as hideously as possible. And that's without even getting into the Simians, Xillians, and various other alien races who have employed their services.
[[/folder]]

[[folder:Literature]]
* The Martians from ''Literature/TheWarOfTheWorlds'' by Creator/HGWells, although it's a somewhat complex example. The author notes that Mars is a dying world, and that the Martians are only carrying warfare sunward so that their species can survive (in the epilogue, it is implied that after the invasion failed they settled for colonizing Venus instead). He also compares them with Imperialists of the 19th century, making the Martians something of a ThisLoserIsYou to his [[TheBritishEmpire primarily British]] readers.
* The [[MeaningfulName Pierson's Puppeteers]] from Creator/LarryNiven's ''Literature/KnownSpace'' series are not just alien bastards, they are [[ManipulativeBastard alien manipulative bastards]]. How so? They maneuvered all of humanity into the sights of the predatory, warlike, technologically superior Kzinti, just to give them some breathing room, then after the war was over used humans as if we were a race of Polish landmine detectors. Plus the thousands of humans they kidnapped and enslaved under the guise of "spacecraft failures".
** On the side of helping us to screw over other races, the Puppeteers set up a starseed lure because they knew that (for their own impenetrable reasons) the Outsiders follow the starseeds. When the Outsiders encountered humanity, they sold us the hyperspace drive. Humans quickly become a much bigger problem for the Kzinti.
** When a Puppeteer told a Human and a Kzinti the truth about their manipulation in ''Ringworld'', both were furious. The human was furious that his race had been forced to fight, the Kzinti was furious that his race had been forced to lose.
* As far back as the 1940s, Creator/CSLewis noted the tendency in sci-fi literature for aliens more advanced than humans to be amoral and regard humanity as inferiors. ''Literature/TheSpaceTrilogy'' was a deliberate reaction against this trend--his aliens are more moral than humanity.
* [[http://www.sff.net/people/lisanne/ Lisanne Norman's]] SholanAlliance series gives us two examples out of numerous interstellar species who are willing to be nice.
** The Chemerians are conniving, double dealing tree-climbing...
** The Valtegans from planet M'Zull have already wiped '''ALL''' life off the face of '''two''' Sholan colony planets for no other reason than that of being Sholans. They then go off and do the same to another planet of Valtegans simply because they are rivals.
* A rather nasty science fiction novel by Charles R. Pellegrino, ''Flying to Valhalla'' is built around the theory that a species looks out for itself only, destroying all competitors. Also a sort-of-sequel, ''The Killing Star''.
* The Prador of the ''Literature/ThePolity'' are a GiantEnemyCrab race whose culture revolves around a [[TheSocialDarwinist Social Darwinist]] "kill-or-be-killed" mindset. Members of the species are cruel to those weaker than themselves and maim or even eat their own children. They are just as sadistic when they go to war with humanity.
* {{Subverted|Trope}} in ''Literature/{{Animorphs}},'' which often explores the implications of any sentient species supposedly being AlwaysChaoticEvil. The main antagonists, the Yeerks, are trying to enslave humans as hosts, but only because their natural forms are weak, blind slugs desperate for the lives other races can enjoy. It's explored further with the Howlers, servants of the {{Sufficiently Advanced|Alien}} EldritchAbomination Crayak; while dedicated to wiping out every other species in the universe, it's revealed that [[spoiler:Crayak keeps them unaware that other species have any sort of sentience or sapience, allowing them to slaughter other races as easily as people playing a video game]].
** The Andalite case is far more interesting. In the beginning of the series, kids look up to their erstwhile saviors, the great and glorious Andalites, and are counting on them to swoop in and save the day. It becomes increasingly obvious, however, that Andalite military command couldn't care less about humans. In the end, their strategy for for winning the war was to ''bombard Earth from orbit'' to take out as many Yeerks as possible.
* Discussed in passing in ''Literature/{{Blindsight}}'': a mention is made of the benevolent aliens of Creator/CarlSagan, then compared with the idea that someone who ventures into space must have strong instincts of conquest and expansion.
* {{Zigzagg|ingTrope}}ed in Pamela Service's ''Under Alien Stars'': Yes, [[AlienInvasion Tsorians]] ''are'' [[ProudWarriorRaceGuy brutal]], [[VichyEarth paternalistic]] [[FantasticRacism bastards]]. [[spoiler: {{Humans|AreTheRealMonsters}} don't have [[FantasticRacism much of a moral high ground]]. And compared to the [[HordeOfAlienLocusts Hykzoi]], ''both'' races [[BlackAndGrayMorality look like saints]].]]
* The Toralii in ''Literature/{{Lacuna}}'' destroy three major cities on Earth just because humans were developing jump drive.
* The Vogons of ''Literature/TheHitchhikersGuideToTheGalaxy'' are every ObstructiveBureaucrat stereotype turned UpToEleven and armed with planet destroying weaponry (and horrible poetry). Even ''evolution'' considers them to be a mistake.
** The Silastic Armorfiends of Striterax are actually worse - [[spoiler:the whole Krikkit War fiasco was an indirect result of [[OmnicidalManiac their desire to destroy the entire universe]]]].
* ''Literature/EndersGame'' is a long deconstruction of this trope. The Formics, during the First and Second Invasions, would board captured ships and colonies and brutally murder the captives - while the recording equipment was still transmitting. Naturally, the humans have a deep hatred and fear of them because of this. [[spoiler:It turns out the aliens did this because they operate as a HiveMind. Killing all the individuals aboard a ship was simply their way of disabling the ship's communications equipment, and they never imagined until it was too late that each individual was an independent, thinking, feeling being. By the time the humans launch their counterattack, the Formics have figured this out and are deeply remorseful for their actions.]]
* Creator/RobertReed's short story, ''Five Thrillers'' has an unknown race of aliens shooting the sun with a relativistic ship, causing it to eject plasma straight at the Earth. Because ''they can''.
* The Masters in ''Literature/TheTripods'', who enslaved humanity with mind control caps and then planned to annihilate life on Earth in the process of making the planet's atmosphere breathable for themselves.
* The Lindauzi of ''The Wild Boy''. They were just trying to avoid their race regressing to wild animals. But they still released a virus on Earth, then released a second wave, killing millions before it was over. And to further endear us, they came with a vaccine, appearing to be saviors. They killed off our pets, cats and dogs, then started breeding humans like dogs to re-engineer the bond they once shared with the Iani, the creatures who originally created ''them''.
* Most aliens in the Franchise/StarWarsExpandedUniverse are pretty variable. PlanetOfHats is in effect and there are many nasty species, but search for long enough and there are always some who feel that MySpeciesDothProtestTooMuch, and individuals can be anywhere from bastards to very much not. However, there are a handful of antagonistic species who are ''never'' shown to have any sympathetic representatives at all.
** The [[Literature/BlackFleetCrisis Yevetha]] are pretty hideously genocidal towards... well, everything. They're also {{Manipulative Bastard}}s, playing nice for a long time so that when they ''did'' start war, the New Republic was caught unawares.
** The Enzeen in ''Literature/GalaxyOfFear: EatenAlive'' similarly play nice, encourage tourism, and make visitors to their world feel welcome, when in fact [[spoiler: the ground [[QuicksandSucks eats offworlders]], and the Enzeen then feed from it.]]
** Subverted nicely with [[Literature/NewJediOrder the Yuuzhan Vong]]. Initially introduced as quite possibly the most implacably evil faction in the setting- the one guy (a pacifist) who tries to negotiate with them gets ritually murdered and has his gem-encrusted skeleton shipped back to his friends for his troubles- but about a third of the way through the series a more openly sympathetic light starts getting shone on certain members of the species, and once [[HeWhoFightsMonsters the Vong's backstory]] is revealed, it's stated outright that they're no better or worse than humans would have been under the same circumstances. Oh, and the guy who murdered the pacifist diplomat? He was a member of a group that were considered particularly extreme and depraved even by Vong standards.
* Subverted in ''Literature/TheFifthWave'' by Rick Yancey. [[NotUsingTheZWord The Others]] are at first depicted as coldly killing off humanity, but then [[spoiler: the main love interest, [[MysteriousPast Evan]] is discovered to be one, and he explains that some of The Others wanted to live side by side with the humans, but were outnumbered by those who wanted to KillEmAll]].
[[/folder]]

[[folder:Live Action TV]]
* ''Series/DoctorWho'' has plenty of good aliens, most notably the Doctor himself. However, the Doctor fights all manner of sundry horrors bent on our demise every other episode.
** Foremost on the list are the Daleks; super-intelligent, genetically engineered, AlwaysChaoticEvil [[ANaziByAnyOtherName space Nazis]] designed to feel no other emotion than hate (though they sometimes display fear and others). They are utterly fanatical about their own [[FantasticRacism inherent superiority]], to the point where civil wars have broken out amongst them if factions start displaying minor differences, and to where they have chosen death when "contaminated" by foreign DNA. Their goal is nothing less than to [[CatchPhrase exterminate]] [[OmnicidalManiac every living thing in the universe]] (and, once, the multiverse) other than themselves, and they often tend to find themselves dealing with Earth.
** The Cybermen (at least the version of them appearing from 1966-1988 and from 2010 onwards) are, basically, alternate humans from Earth's twin planet Mondas who converted themselves into [[CyberneticsEatYourSoul emotionless cyborgs obsessed with the survival of their race]], and the best way to do that is to forcibly convert humanity into them. That they are a direct threat to mankind means that they have also sought to destroy them, or sizable chunks, in the distant future when we manage to successfully fight back.
** The Time Lords themselves are a race of supposed non-interventionists, but they are really a controlling, elitist, and somewhat stagnant race of {{Sufficiently Advanced Alien}}s who, as their name suggests, have mastered {{time travel}}, amongst other technologies. Generally they are not malevolent and have plenty of decent members -- notably the Doctor himself [[note]]for varying definitions of "decent" and "good", given how much blood he has on his hands even before the Time War[[/note]] -- but they throw up plenty of maniacs like {{the Master}} and the Rani, not to mention their insane founders Rassilon and Omega, amongst other miscreants. As the Time War drew to a bloody close they became a race of {{Omnicidal Maniac}}s who were ready to [[ApocalypseHow put an end to time itself]] in an effort to avoid ultimate defeat, which means in their appearance in 2009 they showed up as a villain race.
** The Sontarans are an entire race of {{Blood Knight}}s who are engaged in a 50,000-year war with another species, and to ensure a ready supply of troops turned to cloning, to the point where practically every living Sontaran is now a clone of someone else, resulting in a buttload of uniformity. They usually attack Earth as part of a strategy aimed at achieving victory in their war rather than any particular feelings about us, though they enjoy it when we fight back because to them because WarIsGlorious, always.
** The Master inverts this by holding this view of humanity, revealing to the Doctor that despite the Utopia Project's attempt to find a way to survive the end of the universe, the ultimate fate of humanity is to cannibalise themselves and devolve into [[PsychopathicManchild the Toclafane]].
---> '''The Master''': The human race. [[HumansAreTheRealMonsters Greatest monsters of them all]].
* ''Series/{{Torchwood}}'' has a lot more bastard aliens than its parent show, ''Doctor Who'', but ''Series/TorchwoodChildrenOfEarth'' goes much further: Aliens [[spoiler:repeatedly]] subject humans to [[spoiler:{{Sadistic Choice}}s involving HumanSacrifice just so that [[FantasticDrug they can get high]] [[PoweredByAForsakenChild ... off children]]]].
* The Franchise/StargateVerse is full of these:
** ''Series/StargateSG1'' has the Goa'uld, the Ori and the Replicators.
** ''Series/StargateAtlantis'' has the Wraith and the Asurans.
** ''Series/StargateUniverse'' deserves special mention because in addition to the non-sentient aliens creatures (and even some of the plants) that are desperately trying to kill them, the sentient ones are no better, particularly the race obsessed with ''Destiny'' who make no attempt to communicate beyond "SURRENDER" and "NO ESCAPE", the latter sent after they pursued them into a completely different ''[[SuperPersistentPredator galaxy]]''. {{Lampshade|Hanging}}d by Volker when Rush wants to investigate an energy signature that could be intelligent life; he reminds them that the last time they encountered aliens didn't work out so well. And the time before that. And the time before that... [[spoiler:Maybe they should have listened to him, because this energy signature leads them to the [[AIIsACrapshoot Berserker Drones]]]]
** Also, the franchise as a whole has the Ancients themselves, who are ([[MySpeciesDothProtestTooMuch bar a few notable exceptions]]) the poster boys for NeglectfulPrecursors (although from what we see of their present-day actions or lack thereof and how those threaten their own survival, it may be more of [[TooDumbToLive another trope]] than this one).
* From ''[[Series/{{V 2009}} V]]'' (both 2009 and [[Series/{{V}} predecessor]]): "We are of peace, always". More BlatantLies were never spoken.
* One of the main themes of ''Franchise/StarTrek'' in all its incarnations is a deliberate aversion of this Trope. There is a huge variety of alien cultures out there, and only a handful are treated as objectively better or worse than humanity. And of those, fewer still are depicted as irredeemably evil, with some even becoming allies or members of the Federation eventually. Still, too many episodes to count revolve around the concepts of "Alien Race Does Something Morally Reprehensible That They Think Is Normal", or "Alien Race Acts With Subterfuge Against The Federation For Evil Reasons", or "Human Does Something Of Little Importance And Alien Race Responds With Reckless Force".
** The Borg Collective is one of the few truly irredeemably evil races in all of ''Franchise/StarTrek'', being an insane HiveMind of cyborgs with an insatiable appetite to assimilate anything that might benefit the Collective -- which is everything. Drones that gain individuality are usually decent people, but since they aren't part of the Collective anymore they arguably aren't really Borg anymore either.
*** Even that depends on your definition of evil. If that happens to be manevolence, well the Borg do not hate any species and literally cannot wish harm against them. Their only desire is to advance the Collective, and they act exclusively on that desire. It seems the more powerful they are in an area the less dangerous they - as a single isolated Borg will assimilate just to gain numbers on its side, but in the heart of Borg space they are happy to ignore individuals, ships or even the occasional (simplistic) species if they have nothing to specifically gain from assimilation. They are a major power in the Delta Quadrant, yet other species abound in space surrounding them. In the rare instances they respond to the idea others do not want to be assimilated they act confused, as if the assimilation is a kindness the rejection of which they cannot comprehend. And by all accounts, being part of the collective is quite the experience and apparently not an unhappy life - for a given definition of the word 'unhappy'.
** The Pah-Wraiths of ''Series/StarTrekDeepSpaceNine''. There's a reason the Bajorans consider them to be devils.
* The Vardians of ''Series/{{Tracker}}''. Apparently they *could* cooperate with other races, they just hate doing it and prefer to be in control. They did create a DoomsdayDevice capable of destroying a planet. They're also notorious for betrayal, apparently. The fugitives were of all six of the series' races, but not all of the species were as evil as Vardians. Most of the others were just all the races' criminal element rather than the norm.
-->'''Zin''': Never trust a Vardian. Sorry.
* The Skins in ''Series/{{Roswell}}'', plus Kivar. The Skins wore human skin to blend into Earth's environment. Kivar was the resident BigBad who'd taken over Antar and who the Pod Squad were meant to defeat.
* In ''Series/TheOuterLimits'', episodes dealing with aliens sometimes take this approach. One episode featured aliens that wanted to steal the Earth's atmosphere and even looked like literal devils. But there were just as many episodes with nice aliens who wound up in conflict with humans due to misunderstandings or because HumansAreBastards.
* The ''Franchise/UltraSeries'' practically have these kinds of alien races ''by the dozen''. Then again, the title heroes are, themselves, members of an alien race.
* The Overlords in ''Series/FallingSkies''. They not only invade and destroy a lot of Earth and humanity, they put children in harnesses that turn them into monsterous Skitters. And we aren't the first race they did it with. Subverted with the other alien races, who are pretty much in the same situation as humanity and later bring humans into their rebellion against the Overlords.
* In ''Series/PowerRangersMegaforce'', the Armada often see humanity's traits as weaknesses and their desire to destroy or take over Earth is based primarily on EvilCannotComprehendGood and HumansAreFlawed. It's dialed up in ''Super Megaforce'' where Vekar's [[MonsterOfTheWeek Monsters of the Week]] are decidedly less comical than Malkor's and they're shown to have enslaved the [[SixthRanger Silver Ranger]]'s planet.
* Subverted in ''Series/TheXFiles''. The Greys are a bunch of bastards [[spoiler: but it's not their fault. The Black Oil corrupted and twisted them into monsters just like it does to every other living being.]]
[[/folder]]

[[folder:Tabletop Games]]
* Every alien species in ''TabletopGame/{{Warhammer 40000}}'':
** The [[OurOrcsAreDifferent Orks]] are [[BloodKnight ridiculously violent and warlike]], and think nothing of rampaging across the galaxy and killing everyone they come across, all in the name of the WAAAGH!
** The [[SkeleBot9000 Necrons]] [[OmnicidalManiac want to kill all life in the universe]] to rebuild their old dynasties.
** The [[SpaceElves Eldar]] are {{Manipulative Bastard}}s who [[ItsAllAboutMe would let millions of humans die to save a handful of Eldar]] (it is worth noting that that only happened once, and it was hundreds of thousands of Eldar. [[FantasticRacism The humans in the setting do much worse to the other races]]). Although, given the [[DyingRace situation]] they're in, they're much more sympathetic than most.
** Their cousins, the [[TheFairFolk Dark Eldar]], are even '''worse'''.
** In fact, the only aliens that ''don't'' fit are the [[HordeOfAlienLocusts Tyranids]] (who aren't sentient, but are still driven by a HiveMind that wants to eat the universe) and the [[TheGreys Tau]] (who are more "Aliens Are GoodIsNotNice {{Well Intentioned Extremist}}s", as long as you don't mind living in a place that's equal parts ''Literature/BraveNewWorld'').
*** Oh, and one more thing: the humans of the setting? [[HumansAreTheRealMonsters They]] [[BlackAndGrayMorality aren't]] [[HumanityIsInsane much]] [[AbsoluteXenophobe better]].
* Averted in ''TabletopGame/{{Traveller}}''. The closest to this is the K'kree which are herbivores on a holy war against carnivores (and omnivores, since those also eat meat), but even the K'kree have good qualities and are not an "evil race" as such. There are no "evil races" in ''Traveller''.
** Likewise in ''Traveller'''s [[MohsScaleOfScienceFictionHardness harder cousin]] ''TabletopGame/TwentyThreeHundredAD''. The major races avoid this trope except for the [[BigCreepyCrawlies Kafer]], and it's {{justified|Trope}} in that [[spoiler: [[BizarreAlienBiology their biology only allows them full intelligence when they're fighting or fearful via an adrenaline analog]]]].
[[/folder]]

[[folder:Toys]]
* In ([[TransformersShatteredGlass almost]]) every version of the ''Franchise/{{Transformers}}'', The Decepticons. Usually, they're on Earth for a reason, but even if they get what they want, they mostly still decide to stay and cause untold devastation anyway. They are a faction of merciless warriors, led by a fanatical tyrant (Megatron) who willingly destroyed most of their home planet, as well as a large percentage of their own species, so it probably shouldn't be surprising that they would show even more disdain to another species that are like insects by comparison.
** Some versions of the franchise (*''ahem''*[[WesternAnimation/TransformersAnimated Animated]]*''ahem''*) have less than flattering portrayals of the Autobots as well.
** Stories that feature races other than humans show that because of this warmongering, Cybertronians in general have a very bad reputation.
** There's also the [[StarfishAliens Quintessons]], who manage to be ''worse'' than the 'cons. Manipulative, greedy and cruel, they'll mess with a planet for money, resources or [[ForTheEvulz for the kicks]]. They usually try and conquer Cybertron, because as far as they're concerned the Transformers are just some of their products gone haywire. Anyone who ends up on their planet either gets eaten by the [[EverythingTryingToKillYou local wildlife]] or dragged before a KangarooCourt which always ends with the victim being eaten alive.
[[/folder]]

[[folder:Video Games]]
* The [[StarfishAliens Grekim]] and Vecgir from ''VideoGame/{{Achron}}'' introduce themselves by wiping out three human colonies. They then engage and shatter the largest and most advanced fleet humanity has ever assembled... and then turn on each other.
* The Furons from ''VideoGame/DestroyAllHumans'', as the title suggests. Also mildly deconstructed. The reason the Furons are collecting DNA from humanity is because they've driven their race into sterility through constant conflict and war. In other words, by acting like stereotypical AlwaysChaoticEvil aliens, they're essentially driving their race into extinction.
* Zemus from ''VideoGame/FinalFantasyIV'', who is coincidentally the least human-looking of the moon dwellers. (He is blue-skinned, with a bald dome.) He was the only Lunarian who opposed peaceful coexistence with humans, and sought to take over their planet.
** The Terrans from ''VideoGame/FinalFantasyIX'' were thinking along similar lines. After several failed attempts at keeping their dying planet alive, they went into stasis while their guardian, Garland, works to terraform Gaia and make their world live again.
** Jenova from ''VideoGame/FinalFantasyVII'' is an odd mix of humanoid and gross, veiny alien. Folklore suggests that she is a shapeshifter who mimics the appearance and voice of humanoids; hence her being stuck in mid-transformation from long-haired beauty to a Lovecraftian mass of wriggling tendrils.
* The Combine from ''VideoGame/{{Half-Life 2}}'' had been draining the Earth of its resources for the past two decades, and letting roads and cities rot. The surviving humans are essentially imprisoned in the few cities not overrun by alien fauna and are ruled with an iron fist, chemicals in the water, and a dampening field that prevents natural reproduction.
** And that's not the worst of it. The Combine is experimenting with humans in order to find the best method of converting them into a new Synth race like the Gunships. The Overwatch is the most successful; the Stalkers the least. By the time the Combine is done, humanity won't be human any longer.
* This trope in video games dates back to ''VideoGame/SpaceInvaders''.
* The ''VideoGame/{{X-Com}}'' games use this in spades. Attempts to communicate with the aliens are made, but it's generally [[WeComeInPeaceShootToKill a bad idea]].
** In ''TheBureauXCOMDeclassified'', the Outsiders (AKA Zudjari) are PlanetLooters who have ruined their own planet and dozens of others and have to keep on conquering new worlds in order to maintain their unsustainable culture. In fact, they have managed to conquer and enslave the Sectoids and the Mutons. Earth is just their latest attempt, but it can also be their last.
** In ''XCOMEnemyUnknown'', the Ethereals want humanity in order to [[spoiler:create the perfect SuperSoldiers, with all the others races being failures. Assuming you succeed in destroying TheMothership, their attempt has GoneHorriblyRight]]. Interestingly, the Sectoids and the Mutons in this game look the same as in ''The Bureau''. According to Firaxis, ''The Bureau'' can be treated as a sort-of prequel, meaning that, as soon as the Zudjari were defeated by the original XCOM, the two races were re-conquered by the Ethereals.
* Portrayed to some extent in ''Stars!'' and other 4X space empire games. Each race is alien to each other, and the players generally think nothing of bombing/killing millions of colonists of the opposing players whose only crime, presumably, is not being the same race. No concept of assimilation (or at least subjugation, sparing lives) is typically offered.
** ''VideoGame/MasterOfOrion'' is an exception, as a planet's civilian population can be either annihilated or assimilated after its military is dealt with. Certain government types get bonuses or penalties for how quickly assimilation happens (for example, [[HiveMind Unification Governments]] assimilate new populations very slowly, while [[FeudalFuture Feudal Governments]] will have their planets instantly assimilate as the local Baron kowtows to a new master), and the Democracy government doesn't even have the ''option'' to annihilate. The depth of bastardry depends entirely on the player's actions.
* The Zerg from ''VideoGame/{{Starcraft}}'' are largely mindless, but are controlled by Cerebrates and the Overmind. Who are all pretty bastardly. As a HordeOfAlienLocusts, they desire to assimilate the most favorable genetic traits from sentient species and essentially swallow them whole. They get a dose of HumansAreTheRealMonsters mixed in when Sarah [[NamesToRunAwayFromReallyFast "Queen of Blades"]] Kerrigan takes over, even explicitly referring to herself as [[BadassBoast "Queen Bitch of the Universe.'']]
** The Protoss and [[HumansAreTheRealMonsters Terrans]] also have their moments, and if the sequel is anything to go by, [[{{Precursors}} the Xel'Naga]] aren't/weren't exactly saints either. The latter's [[BiggerBad true enemies]] are probably worse.
* The Shroobs in ''VideoGame/MarioAndLuigiPartnersInTime'' play this as straight as possible, destroying entire towns for very little reason and using the life force of native species like Toads for UFO fuel. Not set on Earth, but the town being destroyed during Christmas is definitely the bastard part of this trope.
* The ''Franchise/MassEffect'' series generally averts this, giving every species more or less the same saint-to-asshole ratio. The batarians are as close as it gets, and that's largely because any batarian outside their home space is, by definition, an outlaw.
** The Reapers. Can't get much worse than AbusivePrecursors who are also {{omnicidal|Maniac}} and {{sufficiently advanced|Alien}}. Justified considering [[spoiler: they're all basically insane AIs who are trying to function off of downright ''broken'' logic and programming that tells them that the solution to mass extinctions is ''to personally cause the mass extinctions themselves''.]]
** There's an asari on [[WretchedHive Illium]] who thinks that Aliens Are Bastards (and since [[CaptainObvious she's not human]], [[HumansAreTheRealMonsters we count]] [[HumansThroughAlienEyes in that statement]]), or at least horrifically incompetent. Subverted when Shepard calls her out on her FantasticRacism and she reveals that she was once married to a quarian and lost both of her daughters during the attack on the Citadel, making it clear that it was [[OutlivingOnesOffspring simply the grief talking]].
** The Yahg can certainly count. Giant bipedal aliens who are the apex predators of their planet (Parnack). When they were discovered, the Council sent a delegation of ambassadors to meet them. They immediately slaughtered all of the ambassadors and the planet was immediately deemed off-limits to all races.
*** Even in their case, its not a clear cut thing. With the Yahg possessing ocular setups with more in common with Jumping Spiders than anything else, they are capable of easily picking up on the tiniest details. Like body-language - the sort that might indicate lying. What the diplomats actually told them is unknown, but it's clear that little ability was not something they appreciated.
** In the first contact war, the Turians were pretty bastardly too. Due to a cultural dissonance, they assumed that, like them, every human was military trained and simply in reserve, so they were left rather confused when humanity considered them horrible monsters for attacking civilian targets. Even after the council put a stop to the war, some Turians (such as the instructor at Kaiden's biotics academy) continued to be right assholes to humans, though thankfully most of them chilled out by the time the games start.
* ''VideoGame/DukeNukem3D'', coupled with MarsNeedsWomen. Those alien bastards are gonna pay for shooting up his ride.
-->"''Nobody steals our chicks... and lives!''"
* ''SinsOfASolarEmpire'' has the Vasari who eventually get a racial bonus towards enslavement.
** Subverted in ''Rebellion the Loyalist''; Vasari stick to their plan on looting worlds and leaving, but the Rebel Vasari also want to do the same, but they are willing to bring the TEC, and Advent along with them.
* ''Franchise/{{Halo}}'' gives us the Covenant. Which is led by its 'Prophets'. These Prophets have declared that humans are sacrilege incarnate and must be cleansed from the galaxy. Bastards indeed. Even worse is the reveal that [[spoiler:the Prophets realized that [[HumansAreSpecial WE]] are [[{{Precursors}} their gods]]' real descendants and they passed their Mantle to us, so they resolve to kill us lest their thousand-year-old Covenant founded on convincing their people that THEY are destined for godhood goes down the drain.]]
** Subverted with (most of) the other members of the Covenant. The Elites are the ProudWarriorRaceGuy types who just follow orders, and actually respect the humans for their fighting spirit. When they found out the [[IronicName truth]], [[spoiler: they ally themselves with the humans and win the war for them]]. The Grunts are just an enslaved race who are forced to work as CannonFodder and don't have any real grudge against the humans. Same thing with the Hunters, who were forced by the Covenant to join them if they wanted their planet saved from been nuked, and the Engineers, who even tried to make peace from day one of the war. [[spoiler:The major part of them would ally with the humans too during the Covenant Civil War]]. The [[MeaningfulName Jackals]] are just HiredGuns who are OnlyInItForTheMoney, but they [[spoiler:remained loyal to the Prophets during the civil war]]. Played straight with the Brutes, who are savages in the Covenant ForTheEvulz anyway, and the Drones, who are too {{hive mind}}ed to think independently, and played completely straight with the [[TheVirus Flood]].
** [[{{Precursors}} The Forerunners]] were said to be a highly advanced, wise, and peaceful species. The first two parts were true. The latter? [[spoiler:Instead they conquered humans and forcibly devolved their society down to the literal Stone Age. Ironically, they did this because humanity appeared to be destroying their colonies, but it turned out the humans were actually trying to contain the Flood, with Forerunners caught in the crossfire.]]
** Their creators the Precursors were no better, [[spoiler:as they would create new species but then exterminate them if they didn't like the result. The last time they tried it, the Forerunners rebelled and wiped out the Precursors themselves. But a few remained, plotting their revenge...]]
* What do you get when you blend this trope with the HumansAreTheRealMonsters trope? You get ''AlienVsPredator''. There is all-out war between everyone and everything and they all kill each other for petty reasons (Xenomorphs [[ForTheEvulz for fun]], Yautja for some few more bits of pride and humans for resources they don't need, power or fun as well).
* ''VideoGame/UFOAfterBlank'' starts off with aliens called Reticulans seeding Earth with a [[TheVirus biological agent that eventually kills off most of the life on the planet]]. The agent was actually used to grow a huge web of alien biomass called Mycelium, which the Reticulans planned to incorporate into a [[GeniusLoci planet-sized supercomputer with godlike psionic powers]].
* The Terrans in ''VideoGame/{{Freespace}}'' had once outright hated the Vasudans for this reason during the Great War. Naturally, the Vasudans had the [[HumansAreTheRealMonsters same opinion about Terrans]]. Then came along the vastly more powerful [[OmnicidalManiac Shivans]]...
* Deconstructed in ''VideoGame/JeffWaynesWarOfTheWorlds''. The Martians only invade Earth because their planet and their species is dying, all their efforts to maintain a habitable biosphere have failed, and the surviving population are so desperate that they have actually started ''lynching'' their leaders until they come up with a solution.
* [[TheLegionsOfHell The Burning Legion]] of the ''VideoGame/{{Warcraft}}'' franchise. They all hail from other worlds -- some from ''[[AnotherDimension other dimensions]]'' -- and thanks to [[TheCorruption fel corruption]], are all bastards.
* The ''VideoGame/StarControl'' series has several fairly nice (if quirky) alien races, but has its share of bastards as well. The most obvious are main antagonists [[AbsoluteXenophobe the Ur-Quan]], who depending on which faction you're dealing with either gives you a choice between becoming their slave-soldiers and being stuck forever on your home planet, or kill you dead, no choice given (although their StartOfDarkness does give them [[FreudianExcuse an understandable motivation]] for their acts).
** The Dnyarri are an evil race of powerful psychics who enslave other races because they are too lazy to do anything for themselves. When they enslaved the Ur-Quan in the distant past, their first orders were to have them attempt genocide on their former allies in the Sentient Millieu. The Chmmr outright call the Dnyarri the devil.
** Similarly, the Ilwrath are a spider-like species that revels in death and pain. But, like the Dnyarri, they are not the main antagonists in the games.
* The Vortex from ''VideoGame/EccoTheDolphin'', who use Earth as their all-you-can-eat buffet every 500 years until Ecco fights back.
** The Foe in the reboot timeline seem to exist only to conquer various worlds.
* In ''VideoGame/StarTrekOnline'', [[spoiler:the Iconians play this straight unlike most alien races in Star Trek. They are responsible for all of the recent conflict in the galaxy and are bent on re-establishing their empire. The Iconians truly live up (down?) to the name the other races gave them: the Demons of Air and Darkness.]]
* The Kreegans in the ''VideoGame/MightAndMagic'' series. Given their appearance and behavior, it's not hard to see why people thought they were actual devils.
* The Tasen in ''VideoGame/{{Iji}}'' invade and decimate the population of Earth. And then [[spoiler:the Komato, another alien race, turn up and begin exterminating ''them'']].
* ''VideoGame/{{Fallout 3}}'': The aliens from ''Mothership Zeta'' have been abducting humans and performing horrific experiments on them for the past 600 years, for reasons unknown. It's also heavily implied that it was ''they'' who launched the nukes that started the Great War and ravaged the Earth, [[PassThePopcorn for no other reason than to see what would happen]].
[[/folder]]

[[folder:Web Comics]]
* ''Webcomic/TheCyantianChronicles'' gives us the Moulin Phedra, AKA the [[UnusualEuphemism Squid]]. They wanted to have some new sport fighters for their fighting pits. Their creations drove them off.
** More recently we have been introduced to the Rastin. One of them kidnapped one of the main characters. The Rastin ship's commander implied that some of his passengers/crew did this sort of thing all the time.
* The [[AllTrollsAreDifferent trolls]] in ''Webcomic/{{Homestuck}}'' start out as ''literal'' Internet {{Troll}}s, and are revealed to be children of a race consisting of ScaryDogmaticAliens [[spoiler:who created our universe]]. However, in some ways subverted, in that some of the trolls (such as [[GenkiGirl Feferi]] and [[WheelchairWoobie Tavros]]) are actually fairly nice once we learn more about them, and some of the ones who are jerks get a fair amount of CharacterDevelopment over the course of the story. It's implied that the trolls being forced to work together, along with their interactions with the human kids, is "humanizing" them to an extent.
** It turns out the trolls were only ScaryDogmaticAliens thanks to [[spoiler:the influence of Lord English's agents -- Doc Scratch, the Handmaiden, and the Condesce.]] In a session without this outside interference, the trolls were a peaceful race.
*** Though this in turn is subverted when we meet the members of the "peaceful" session, and they're a collection of the most banal stereotypes of shallow modern suburbia, combined with deconstructive parodies of how the fandom perceived the initial troll characters. In short, they're a nasty bunch of hypocritical backstabbing jerks themselves.
* ''Webcomic/TheLydianOption'' involves a prison filled with aliens hostile to humanity. Outside the prison, aliens resent humanity for winning the Spiral War - inside, humans lack protection and must travel together as a group.
* In ''Webcomic/{{Spacetrawler}}'' the G.O.B. will declare a species "non-sapient" for reasons up and including bad fashion sense and their technology is built by a race of highly intelligent but weak-willed (and therefore non-sapient) aliens known as "Eebs". And the AnimalWrongsGroup devoted to Eeb rights shanghaied six humans from pre-contact Earth into helping them. And then it turns out that [[spoiler: Eebs are only weak-willed because of [[PowerLimiter brain clamps]] placed on them at birth, and they're naturally psychopaths.]]
* In ''Webcomic/{{Terra}}'' the Azatoth have BloodKnight tendencies, practice slavery, and antagonist Azatoth, particularly the [[NebulousCriminalConspiracy Shadow Cabal]], have little respect for other races' concept of civilians. [[HumansAreBastards The UEC isn't really any better, however.]]
* In ''Webcomic/Jack'', the Arc Debs involve an alien race who plan on invading planets, and they have no known reason for doing this. They also ruthlessly kill the soldiers stationed there during the story. Probally one of the worse parts was when they gunned down an Injured Arthour Sullivan for en SECONDS straight. In other words, they're genocidal assholes.

[[folder:Web Original]]
* In ''Literature/{{Cradleland}}'', the alien ''ba'thulaz'' had used humans as cattle and slaves, and still viewed them as such even a thousand years after they were overthrown in a slave uprising and forced to flee. [[spoiler: [[HumansAreTheRealMonsters Humans]] were not much better, as the slaves were purchased from human slave traders on Earth during the MiddleAges]].
* In the ''GlobalGuardiansPBEMUniverse'', the Daribi invade the Earth three times because once, two hundred thousand years ago, they used the planet as a forward base and now want "their" planet back. They get beaten back worse after each invasion, killing nearly three million people and levelling three cities in the process.
** Also the Xorn, a {{Proud Warrior Race|Guy}} who invaded Earth just because it was there to invade. They ended up killing nearly a billion people worldwide and came close to wrecking Earth's ecology by introducing alien life. And when they left, they stranded hundreds of thousands of imported alien slaves, who had to find new lives on a new planet, surrounded by humans who were hostile to most of them.
* In ''Machinima/FreemansMind'', Gordon frustratedly provides this page's quote after getting ambushed and zapped by a Vortigaunt for the ''n''th time.
** Which is pretty ironic, since Vortigaunts are some of the only aliens that ''aren't'' bastards after they are freed.
* In WebVideo/TheCinemaSnob's "Catching Up" review of ''Film/DarkSkies'', he points out that the alien invaders pretty much come to Earth for the sole purpose of being dicks.

[[folder:Western Animation]]
* [[WesternAnimation/LooneyTunes Marvin the Martian]] was an AffablyEvil bastard in his shorts, being perfectly willing to [[EarthShatteringKaboom murder billions of lives]] solely because Earth [[DisproportionateRetribution was blocking his view of Venus]]--though like most of WesternAnimation/BugsBunny's foils, he's not too bright.
* In ''WesternAnimation/InvaderZim'', the Irken Empire. Not only are they after total intergalactic domination, but, they destroy all the life on a planet, just to build a [[PlanetOfHats parking lot on it!]]
** The humans [[HumansAreTheRealMonsters aren't any better]], if not [[HumansAreMorons worse]].
* ''WesternAnimation/AmericanDad'': Roger, so very much. However, it is later revealed that this is justified, as his species needs to "let their bitchiness out", or else it will turn to bile and poison them to death.
** One episode revealed that the reason Roger's species abandoned him on Earth was because he wasn't ''enough'' of a bastard, he was too nice by their standards, so they turned him into a crash test dummy for a spaceship and just left him there.
* Averted and subverted in the ''WesternAnimation/{{Ben 10}}'' series, where there are good aliens, evil aliens, and everything in between. With some minor exceptions (most notable being the [[TheEmpire Inku]][[BloodKnight rsians]]), it seems most aliens avert the AlwaysChaoticEvil status ([[TheMentor Azmuth]]'s assistant, Myaxx, is from the same species than ''[[BigBad Vilgax]]'', yet is in no way as evil as he is, and most of their species aren't portrayed as evil either.).
* ''WesternAnimation/TeenTitans'' did have some good aliens (one of the main heroes was one, after all), but normally an alien species would only show up if some of their members were going to be the episode's villains. {{Lampshade|Hanging}}d with The Source, whose only reason for wanting to [[EarthShatteringKaboom blow up the Earth]] is "It is our way."
* JustifiedTrope in ''WesternAnimation/AxeCop'': When Axe Cop kills the last remaining bad guys on Earth, he decides VictoryIsBoring and wishes for every alien to be a bad guy so he can go kill them.

* StephenHawking believes any aliens that would come to earth would be imperialists [[RecycledInSpace (in space)]].
* Others have argued that any species behaving like the typical version of this trope would be unlikely to cooperate among themselves long enough to discover CasualInterstellarTravel in the first place.
