Line #50 Main/InscrutableAliens


1	->''"About Khaak culture absolutely nothing is known. From their behaviour it is difficult to determine a recognisable analogue, prompting some Argon exobiologists to comment on the 'fundamental impenetrability' of the modes of thought of extraterrestrials."''
2	-->-- ''[[VideoGame/{{X}} The X-Encyclopedia]]''
3
4	Sometimes, it's considered a mark of good WorldBuilding in the ScienceFiction genre to develop an alien culture like you would any aspect of the story. To talk about their history, culture, motivations and character.
5
6	Other times, writers find it best to leave these questions [[RiddleForTheAges for the ages.]]
7
8	The aliens are simply there. Any attempts at communication are met with silence. Their origins, motives, and plans are all mysterious. Nothing is known about their society and culture. Their actions come across as bizarre, incomprehensible, and frequently terrifying. Your best bet is to stay far, far away from them and not do anything to attract their attention, because the consequences of even being in their way are frequently horrific, ''let alone'' when they have noticed you.
9
10	This trope is common in [[AlienInvasion invasion literature]] and {{Horror}}, in order to add to the "other-ness" of the aliens.
11
12	Often the aliens in question are StarfishAliens and may speak a StarfishLanguage. Will often act on BlueAndOrangeMorality. Given most are malignant invaders, many times they're PlanetLooters. Contrast this with ScaryDogmaticAliens, who are mainly used as allegories of real-life ideologies ([[AuthorTract usually ones the author dislikes]]), while these aliens are completely inhuman. While they are not required to be {{Eldritch Abomination}}s, per se, they usually wind up in this territory.

14	''Please'' don't confuse this trope with InscrutableOriental.

20	[[folder:Anime & Manga]]
21	* The JAM from ''Literature/SentouYouseiYukikaze''. It has been 33 years since their attempted invasion of Earth. In that time, the Faery Air Force has been attempting to figure out what they are and why they invaded. After over 3 decades of fighting, they have learned absolutely nothing about them. Everything about the JAM that ''might'' be remotely accurate is all pure speculation. It also does not help that they may or may not even have physical bodies, as the only thing the FAF has seen of them are their aircraft and the makeshift "runways" they use to launch from.
22	* The Zai from ''Literature/GirlyAirForce'', which cribs ''heavily'' from the JAM example above from ''Yukikaze''.
23	* While the audience may have obtained a lot of information about the Angels of ''Anime/NeonGenesisEvangelion'' in between the show's initial release and the current day, most of it is strictly AllThereInTheManual territory and a manual that is ''[[NoExportForYou very]]'' hard to get at that. ''InUniverse'', most of the characters have no damn idea of what the Angels are or what the heck they plan and the ones that ''do'' have a clue are both absurdly cryptic about it and it's hinted that they only have ''just enough'' information to make [[AssimilationPlot their schemes]] and that is about it.
24	[[/folder]]
25
26	[[folder:Comic Books]]
27	* ''ComicBook/{{Trees}}'' follows the many misadventures of people who are part of an Earth that knows that aliens exist, because multiple gigantic black "posts" landed around the world (the TitleDrop lies on the fact that humanity has had as much luck contacting the aliens that sent or are inside said posts as they would have asking a tree to talk, and so "like trees" the posts watch the world unfold).
28	[[/folder]]
29
30	[[folder:Fan Works]]
31	* ''Franchise/{{Godzilla}}'' fanfiction ''[[Fanfic/AbraxasHrodvitnon Abraxas]]'': We don't know much about the ancient alien AbusivePrecursors called [[Characters/AbraxasHrodvitnonTitansAndOtherCreatures the Makers]] who transformed [[DraconicAbomination Ghidorah]] into what it is now, except that they were at least loosely comparable to humans in size and shape from Ghidorah's perspective, they had advanced enough technology to turn alien animals into a gigantic, planet-destroying, space-traveling DraconicAbomination with eons-spanning immortality, they earned Ghidorah's ire by hurting it with their experiments to turn it, they set Ghidorah loose from its cage to [[BioweaponBeast destroy something for them]], and they ''weren't'' powerful enough to stop Ghidorah from killing them when it turned against them and made the Makers die screaming in revenge. ''Fanfic/AbraxasEmptyFullness'' reveals [[spoiler:that the Makers made Ghidorah to commit genocide against another planet whose people had "refused" the Makers' "offers" three times, and that the Makers regarded concepts of religion and faith as "primitive superstition" which they'd moved past]].
32	[[/folder]]
33
34	[[folder:Films -- Live-Action]]
35	* The true motive and appearance of the aliens in ''Film/Annihilation2018'' remains mysterious.
36	* ''Film/{{Arrival}}'' essentially takes this type of alien and has the protagonist attempt to communicate with them despite their inscrutability. They appear without warning in vessels shaped like giant lenses, with no obvious technology inside or outside. They look like giant seven-fingered hands, and have nothing resembling a face. They let humans in at scheduled times, apparently just to tromp around in front of them making incomprehensible noises, sometimes making jagged black circles out of fog. [[spoiler:When Louise becomes relatively fluent in their language, she gains a sort of MentalTimeTravel ability. She doesn't know how this works; it's {{Hand Wave}}d as having something to do with the non-linear language structure. The aliens tell her that humanity will need this inexplicable time-warping language to help them with something in 3000 years, then they disappear; that's as close as we get to knowing anything substantive about them.]]
37	* ''Film/AsteroidCity'' is all about this. An alien arrives in a small town, steals the town's local meteor tourist attraction, disappears, then returns and gives the meteor back before leaving yet again. It never explains itself or why it did those things. [[RiddleForTheAges The audience and characters alike are left to speculate about it]]. Lampshaded in the [[NestedStory upper layer of the plot]], where Creator/JeffGoldblum — the actor playing the alien in the ShowWithinAShow — points out that the alien is more [[AllegoricalCharacter a metaphor and representation of the story's themes than a real character]].
38	* The aliens in ''Film/BattleLosAngeles'' don't make any attempt at contact before they crash in and start killing people. One character suggests the aliens themselves are as clueless as the humans fighting them, being mere grunts shipped off to fight with no idea why, though it's hinted they're PlanetLooters siphoning Earth's water.
39	* ''Film/{{Brightburn}}'': The aliens that Brandon belongs to are this, in [[DarkerAndEdgier stark]] [[PlayedForHorror contrast]] to [[ComicBook/{{Superman}} Jor-El and his fellow Kryptonians]]
40	* ''Film/CloseEncountersOfTheThirdKind'' is quite possibly the TropeCodifier. The aliens do bizarre, inscrutable things like abducting people, placing things they took in the wrong location, meddling with machines, flying around seemingly aimlessly, and all sorts of other general weirdness. We never learn why and they certainly never explain themselves; it's not til the end that anybody even manages to communicate with them to any real extent. They're not malevolent, just something beyond current human understandings.
41	* ''Film/IndependenceDay'': The aliens just show up and blow up cities, the only time they communicate with humans is when one is taken prisoner and takes telepathic control of a scientist in order to demand its release.
42	--> ''Peace? '''No peace'''.''
43	* ''Film/IndependenceDayResurgence'': It is revealed that the aliens that were defeated in the first film and the ones thar are being faced this time are a HiveMind and like to extract planetary cores. There's also a lot more than a single fleet.
44	* ''Film/{{Nope}}'': The UFO [[spoiler:appears this way at first as it showed up out of nowhere and doesn't seem to have any motives until OJ realizes it's actually a single alien organism motivated by animal instinct.]]
45	* [[{{Precursors}} The Engineers]] in ''Film/{{Prometheus}}'' seeded life on Earth billions of years ago, guided early humanity and left maps to their nearest outpost, then two thousand years ago decided to send a ship armed with bio-weapons to destroy everyone, the only thing that stopped them being that [[TurnedAgainstTheirMasters the weapons broke out]]. One of them escaped and made it to a stasis pod, to be awakened 2000 years later by human explorers. [[RidiculouslyHumanRobots David]] had a grasp on their language and even spoke a few words to it, but its first act upon waking up was to start killing people and launch the ship.
46	** It's even stranger when you consider that this impossibly advanced race is genetically ''identical'' to humanity. They look like humans but are ''utterly alien''.
47	* The alien probe in ''Film/StarTrekIVTheVoyageHome'' approaches Earth emitting an extremely powerful signal that resembles the calls of (by then extinct) humpback whales, and all other attempts to communicate with it (including recordings of whales) fail completely. It leaves when Kirk and company manage to travel into the past and retrieve a couple whales to give it a real answer, and nobody ever figures out what it wanted to know, where it came from, or who built it.
48	[[/folder]]
49
50	[[folder:Literature]]
51	* As with many AlienInvasion tropes, the TropeCodifier is probably ''Literature/TheWarOfTheWorlds''. The Martians make no attempt to communicate and the humans can only speculate on their motives.
52	* The ''[[Literature/EndersGame Ender]]'' series has a word for such a species: varelse. More than one of the species placed in this category were later reclassified as the understanding between them and humans improved.
53	* The entire planet in ''Literature/{{Solaris}}'' is an EldritchAbomination, the workings of which are fundamentally incomprehensible; what it does is frequently hard to describe, and ''why'' it does these things is wholly beyond anyone's grasp-- the scientists studying it can't even figure out whether or not it's trying to communicate with them. At least a third of the book consists entirely of the protagonist recounting various scientific papers hypothesizing about how and why Solaris works-- his point being that they are ''all'' nothing but blind guesses with equal chances of being true or untrue, because none of the available facts permit Earthlings to come to any rational understanding of it.
54	** Similarly in ''Literature/{{Fiasco}}'' the alien civilisation turns to be completely out of the human frame of reference, frustrating the protagonists to no end. This trope tends to resonate throughout Creator/StanislawLem's novels in subtler ways.
55	* The Ark Megaforms in ''Literature/SpaceMowgli'', though they do attempt to communicate with humans via the title character.
56	* The Wanderers in the ''Literature/NoonUniverse'' novels: humanity finds traces of their presence all over the galaxy but has never encountered one in person.
57	* Variation in ''Literature/{{Blindsight}}''. The alien ship does make contact but the crew quickly figure out that they're talking to a [[http://en.wikipedia.org/wiki/Chinese_room "Chinese room"]]. They spend a lot of the novel trying to figure out whether the giant starfish-like creatures patrolling the ship are sentient or just drones of some kind as they make no attempt at communicating. The truth is far more sinister: [[spoiler:the aliens are not sentient, self-awareness is not required to build starships, sentience is an anomaly unique to ''H. sapiens sapiens'' and will be corrected eventually, as things like art, culture, and self-awareness are an utterly unacceptable waste of energy that ensure we will not survive in a galaxy full of far more ''efficient'' aliens]].
58	* Creator/JohnWyndham's ''Literature/TheKrakenWakes'' (retitled ''Out of the Deeps'' [[MarketBasedTitle in the US]]): A group of aliens invades the Earth's oceans. They never contact the human race in any way, and the two sides engage in a war without either side ever seeing the other face-to-face.
59	* Creator/RobertAHeinlein's short story "Goldfish Bowl". Unknown creatures (it's not clear if they're from Earth or aliens) suck a huge pillar of seawater into a cloud and then return it to the ocean. They also send out fireballs that kidnap people. They're never seen by humans and don't communicate with humanity.
60	* Stewart Cowley's ''Spacecraft: 2000 to 2100 A.D.''. The City Ships of Alpha are huge cities that float from one pillar to another at irregular intervals. They have existed as far back as the Alpha Centaurians' history goes. All attempts by the Alpha Centaurians to communicate with their occupants have failed, and all attempts to enter the cities are prevented by a protective force field.
61	* The contagion embedded in the deep space probe in ''Literature/TheAndromedaStrain'' is a crystal-based organism that kills Earth creatures by reorganizing the minerals in their bodies to fit the crystalline template. It turns out that the crystals have predefined stop points, leading to the hypothesis that the organism was created by an extraterrestrial intelligence as a data storage medium.
62	* John Varley's ''Literature/EightWorlds'' series involves a {{Transhuman}} future where humanity has colonised much of the Solar System… and then one day aliens came and evicted humans from Earth, with no (visible) rhyme, reason, nor response when contact was attempted.
63	* In Christopher Nuttall's ''Literature/ArkRoyal'', the aliens ignore all calls for communication and simply dice humanity's ships to pieces. [[spoiler:However, late in book 2, a faction of the aliens attempts to make contact, before being destroyed by the war faction.]]
64	* In ''Literature/TheNamelessWar'' the Nameless make no attempts at communication; expeditions after the Mississippi Incident discover their handiwork, but not the Nameless themselves. [[spoiler: In Last Charge, the Nameless do offer terms of surrender-- humanity must stop breeding and go extinct peacefully.]]
65	* Creator/JanuszZajdel had these in ''Limes Inferior'' (very inscrutable, we can only speculate why they [[AlienInvasion invaded]], and most humans don't ''even know'' there's been an invasion in the first place), as well as ''Wyjście z cienia'' (we get a chapter from their point of view).
66	* The Presger in ''Literature/ImperialRadch'' exist mainly as an unknowable outside force that has put a dampener on [[TheEmpire The Radch]] by proclaiming humans a 'significant' species that are worth not being disassembled in an amusing fashion. From what little we learn from one of their ArtificialHuman 'translators', their way of thinking is completely alien to ours and they don't seem to understand individuality or personhood, or at least not in a way translatable to us.
67	* ''Literature/EdenGreen'' follows a rationalist young woman attempting to learn the origins of the alien needle monsters invading her city, including the horrifying symbiote they sometimes transmit to humans. After [[spoiler:crossing over to their world, she discovers a mountain stronghold, abandoned for centuries (or more), and gains zero useful information about the monsters, symbiote, or ancient alien civilization]].
68	* Creator/NancyKress's short-story "Savior" starts TwentyMinutesInTheFuture, when an alien ship lands in Minnesota and... just sits there, completely inert and quiet, protected by an impenetrable force field, for the next three ''centuries''. Civilization experiences a minor collapse, and then bounces back better than ever, and still the ship just sits. It isn't until researchers in China create the first [[spoiler:quantum-based artificial intelligence]] that the ship suddenly takes action and [[spoiler:steals the AI, apparently to protect it.]] But we still have no idea how to communicate with it or any real idea of what its motivations might be.
69	* In ''Literature/TheThreeBodyProblem'', this is the key issue that makes the galaxy [[CosmicHorrorStory such a terrible place]]: because it's so hard to understand other species, it's essentially impossible to establish trust, civilisations have to assume everything Out There is hostile, and as such, the objectively correct response to first contact is to schedule extermination. [[spoiler: Later subverted, as the universe isn't ''completely'' full of hostile life, but even friendly aliens consider it gauche to ask where someone's home planet is.]]
70	* In ''Literature/StolenSkies'', the aliens responsible for UFO sightings exist in multiple dimensions, and have bodies and minds fundamentally different from anything on Earth. The few times a human has interacted with one with any degree of success, it's been when one of the aliens has become trapped within local spacetime and attempted to make some (always incomplete and ultimately unsuccessful) attempt to adapt to local conditions, and even then only ever get a tiny vague glimpse of their thought processes and intentions.
71	* ''Literature/AllTomorrows'': The Qu are a vaguely insect like species of extraordinarily advanced biologists. They invaded the galaxy very suddenly and violently, and after conquering humanity's budding galactic civilization, they removed humanity's sapience and bio-engineered them into thousands of post-human subspecies (some of which don't even remotely resemble humans)... for no apparent reason other than they just could. They spent a few thousand years doing this and building strange monuments on the planets they controlled before just up and leaving as suddenly as they'd arrived, and they haven't come back for millions of years since. The epilogue does mention that the Qu were eventually re-encountered a ''very'' long time down the line by humanity's descendants and "tamed", but doesn't go into specifics.
72	* Played with in ''[[Literature/TheShipWho PartnerShip]]''. Due to a FirstContactFauxPas, humans destroyed the culture of the people of Angalia, who became entirely dependent on human charity as a result. Generations later a lazy survey team evaluating them for personhood determined that they weren't people because they had no technology or culture and no spoken language. The human appointed to keep distributing food would throw the food into mud just before earthquakes to watch them scramble after it and sometimes die in the process. [[ReassignedToAntarctica His replacement]] Blaize was kinder and actually bothered scrutinizing them and even ended up teaching them sign language - a nearly lost language in TheFuture, apparently - and discovered that actually, they were quite understandable. It's just that no one had actually bothered to pay enough attention to figure out their situation and that they can't speak verbally.
73	** Because he broke several laws in helping the Angalians terraform a few miles of their planet and giving them a less precarious legal existence, Blaize was sentenced... to five years of community service working with another species of possible sapient aliens that no one had managed to communicate with, these [[FriendlyNeighborhoodSpider resembling giant spiders]].
74	* ''Literature/RoadsidePicnic'': Nothing at all is known about the aliens who visited Earth and created the Zones. They landed on the planet, milled around for a couple of weeks, and then left, all without ever approaching or interacting with humanity in any way. Why they landed on Earth and created the Zones is one of the driving questions of the book. [[spoiler:It's never revealed. One character's best guess is that they basically stopped for a "picnic" and left when they had rested up, and that all the miraculous technology and anomalies they left behind are just their discarded garbage.]]

77	[[folder:Live-Action TV]]
78	* ''Franchise/StarTrek''
79	** In the ''Series/StarTrekEnterprise'' episode "Silent Enemy," the ''Enterprise'' encountered a species that answered hails but did not speak, and soon turned inexplicably hostile.[[labelnote:Expanded Universe]]The ''Literature/StarTrekEnterpriseRelaunch'' and ''VideoGame/StarTrekOnline'''s expansion ''Legacy of Romulus'' gave them [[AlternateContinuity mutually contradictory names and backstories]]. The ENT relaunch books dub them Gamma Vertians, while STO names them the Elachi and makes them {{mooks}} of the [[BigBad Iconians]].[[/labelnote]]
80	** ''Series/StarTrekDeepSpaceNine''[[note]]primarily; they're also referred to on occasion in late ''Series/StarTrekTheNextGeneration''[[/note]] has the Breen, a race of HumanoidAliens who always go around in [[TheFaceless full-body, face-hiding spacesuits]] and speak only in [[TheUnintelligible a deep electronic warble]]. There's several (often mutually contradictory) pieces of {{exposition}} about their physiology, but apart from them allying with the Dominion in exchange for taking possession of Earth there's little known for certain about them. The contradictory information is acknowledged on-screen as intentional: allegedly their space suits are cooling units because they would die at anything above sub-freezing temperatures, but Weyoun remarks that he's heard that their homeworld is actually temperate, so the "cooling suits" explanation must be a lie to cover...''something'' else. [[labelnote:Expanded Universe]]The ''Literature/StarTrekTyphonPact'' novels explain most of the contradictory exposition by revealing the Breen to be a [[HegemonicEmpire multi-species polity united by a common creed]], rather than a single race. The suits are mostly a countermeasure against FantasticRacism.[[/labelnote]]
81	** ''Series/StarTrekDiscovery'': In Season 4, a strange anomaly travels through the galaxy destroying everything in its path, including inhabited planets. Eventually it is discovered that the anomaly was on a mission to scoop up boronite, and was created by an alien race that lives outside the galaxy. The ''Discovery'' is sent to negotiate with the aliens, who they label as species 10-C, and ask them to stop their anomaly. The aliens prove to be so unlike anything that had been encountered earlier, the universal translator doesn't work, and the team sent to negotiate with them has a very hard time establishing even basic communication.
82	** ''Series/StarTrekVoyager'':
83	*** One episode had them rescue an alien that was so bizarre they had to start from scratch on trying to understand it. Its biology was such that the medical computers, including the Doctor, couldn't make sense of it, and its language was beyond the universal translators capacity to decode.
84	*** In another episode, ''Voyager'' itself played this role. They were in orbit around an unknown planet. Unbeknownst to them at first, time passed much faster for the inhabitants of that planet, so from their point of view ''Voyager'' had been in their sky for centuries, and was a complete mystery to them.
85	*** In "Twisted", an UnknownPhenomenon turns Voyager into a MobileMaze of rooms and decks all jumbled up. The problem sorts itself out and afterwards the crew discover their computers have been scanned and a whole lot of new information downloaded. Janeway believes that the whole affair was an attempt at communication, but the nature and motivations of whoever did this remain a mystery.
86	* ''Franchise/StargateVerse'':
87	** The ''Series/StargateSG1'' episode "Grace" had the ''Prometheus'' encounter a ship which refused to respond to hails and opened fire on them, chased them into a NegativeSpaceWedgie which trapped them both, and abducted all of the crew save Samantha Carter. Even after Carter manages to figure a way to get everybody out (using a hyperspace "bubble"; ItMakesSenseInContext), the alien ship doesn't respond to her when she hails it to demand the return of the crew in exchange for help; it just teleports the crew back.
88	** ''Series/StargateUniverse'' had the crew aboard the ''Destiny'' chased by a StarfishAliens species ([[WordOfGod dubbed the Nakai by executive producer Joseph Mallozi]]) that only transmitted the word "surrender" as a constant enemy, and the crew ends up finding little (if any) information about them during the course of the series.
89	* The Vorlons from ''Series/BabylonFive''. While they can be spoken to, it's debatable whether they can be communicated with.
90	-->'''Sinclair''': Yes we have files on them, very large files. There's nothing in them, of course.
91	* The Midnight Entity in ''Series/DoctorWho'' was so mysterious that not even the Doctor knew what it was, where it came from, or what its goals were.
92	[[/folder]]
93
94	[[folder:Video Games]]
95	* The ''Mothership Zeta'' expansion of ''{{VideoGame/Fallout 3}}'' features the player character fighting his way through an alien space ship. We hear a variety of accounts of (horrifying) experiences with the aliens from a number of people, but the human characters can only guess at the aliens' motives for the atrocities they commit.
96	* ''VideoGame/{{X}}-Universe'':
97	** The Khaak, a species with point-to-point jumpdrive technology that invaded the [[TheAlliance Community of Planets]] in ''X2: The Threat'', and was finally defeated midway through ''X3: Terran Conflict''. No attempts to communicate with them have gotten a response, prompting speculation in-universe that they're just too mentally alien. All the Community of Planets races have learned is that they are attracted to [[{{Unobtainium}} nividium]] and that they seem to be BeePeople rather than individuals (the latter from having cracked their video communication codecs).
98	** The Outsiders from the backstory. They tried to invade this universe from another one some millions of years ago. The Ancients tried every method of communication they could think of, but never got a response. Finally, the Ancients blew up an Outsider scout/colony ship, and that seemed to convince them to back off, but pretty much nothing is known about these beings even now.
99	* The Shivans in ''VideoGame/{{Freespace}}'' never communicate with anyone. They reveal nothing of their culture, or their mindset, or anything about themselves. Their only method of interaction is by destruction. The only things we learn of them are through ruins and left-behind information by the {{Precursors}} that had previously fought them (and lost), and consists entirely of their wild guesses. The endgame of the second game has the Shivans perform some very strange actions that are completely unexplained (and also make clear that they could have wiped out the humans and vasudans way before, but had chosen not to). No explanations are forthcoming either because the games were cancelled at this point.
100	* In [[https://www.youtube.com/watch?v=H91qZSfYLoU the intro video]] to ''VideoGame/SwordOfTheStars'' FirstContact with the Hivers is described thus: ''"They came in silence, no statement of intention, no declaration of war. Without even a demand for our surrender."'' Though, of course, other factions of the Hivers proved more talkative, as well as all the other playable species out there.
101	* ''VideoGame/WorldOfWarcraft'' has the Naaru. They're basically portrayed as space angel windchimes whose only known motivation is stopping the Burning Legion (who are demons/evil aliens). They also have absurdly high tech spaceships which for some reason seem to be built to be run by creatures with hands, like the draenei. Of course, in the Exodar's case, O'ros simply could have been piloting the ship psychically. He either lost concentration or crashed on Azeroth on purpose. The Naaru are known for doing harmful things to themselves to further their goal of stopping the Legion. Basically nothing else is known about them and they cannot/will not communicate in any way beyond psychic image projection.
102	* Arcen seems to be fond of this on the whole. The three alien races from the ''VideoGame/AIWarFleetCommand'' expansions are very non-human in their wants and priorities, though their view of humanity ranges from being friendly to antagonistic depending on the racial group.
103	** This carries over to ''VideoGame/StarsBeyondReach'', where Spire prove to be even weirder when they aren't intergalactic refugees. By contrast (AI) Zenith are clearly making an effort to integrate with other races but they aren't good at it.[[note]]Player Zenith adopt human culture and are not millennia old building sized super-organisms, so they're much more relatable.[[/note]]
104	** VideoGame/TheLastFederation's Obscura put the rest to shame though; they're a particulate based form of life with which communication is impossible.
105	* The Varelsi from ''VideoGame/{{Battleborn}}'' are a [[HordeOfAlienLocusts legion of extra-dimensional cosmic horrors]] who have for thousands of years been dragging stars back to their dark dimension, essentially [[TheStarsAreGoingOut consuming them all]] for some unknown reason. Very little is understood about these {{eldritch abomination}}s and less their actual motives especially since violence seems to be the only language they communicate with to those whose stars they consume. There seemingly is no way to communicate with these beings yet [[TheQuisling Rendain]] was somehow able to broker an alliance with them in order to save his people the Jennerit from the Varelsi's onslaught as he came to the conclusion that the complete heat death and darkening of the universe was inevitable.
106	* ''VisualNovel/MuvLuv'': The BETA are completely inscrutable. Numerous attempts to decipher their language were made, but ended in failure when humanity was unable to determine if the BETA even ''have'' a language. This eventually culminated in using limited telepathy in an attempt to get anything at all out of them... which also failed, as the impressions and thoughts they got from the BETA were too out-of-context and vague to be understandable. All humanity managed to figure out after forty years of research is that the BETA do not consider humans to be living beings.
107	* There is one remote civilization in ''VideoGame/{{Meteos}}'' of which the only known aspect is what their people look like. They have an AstonishinglyAppropriateAppearance, having small round bodies with huge floating hook-shaped heads such that they look like question marks. The size of their planet, population, and people are completely unknown, and as such, they're given the fitting name of simply "Unknown." This civilization is so mysterious that it's the only planet in the galaxy with confirmed intelligent life that [[GeniusLoci Planet Meteo]] does not target for [[EarthShatteringKaboom annihilation]]--even Planet Meteo knows too little about Planet Unknown to attack it.
108	* The Traveller in ''VideoGame/{{Destiny}}'' and [[VideoGame/Destiny2 its sequel]] is surprisingly inscrutable, given its prominence. It's a white orb the size of a small moon, with capability to terraform worlds and bestow technologies, which it uses to uplift species into golden ages before moving on elsewhere. On the rare occassions it choses to communicate, it mostly does so through cryptic dreams and visions. Even its sapient creations, the Ghosts, are unsure as to what its motivations are. The very first species it uplifted, billions and billions of years ago, simply discovered it half-buried in the desert of their homeworld with no further explanation where it came from or how it got there.

111	[[folder:Webcomics]]
112	* None of the aliens in ''Webcomic/AnnaGalactic'' seem particularly talkative [[spoiler:aside from the Hishla, who speaks through Anna while slowly consuming her mind]].
113	[[/folder]]
114
115	[[folder:Web Original]]
116	* The beings in ''WebVideo/GeminiHomeEntertainment'', including [[ReplicantSnatching Woodcrawlers]], [[TheAssimilator Skinwalkers]], [[EldritchOceanAbyss Gardeners]], and [[MeatMoss Nature's Mockery]], are very disturbing in just [[StarfishAliens how inhuman they are]]. They are all the result of a planetwide infection [[spoiler:engineered by a RoguePlanet GeniusLoci who uses the planets of our Solar System]] against humanity. Their end goal, if they really have one, is unknown.
117	[[/folder]]
118
119	[[folder:Western Animation]]
120	* ''WesternAnimation/StarTrekLowerDecks'': Deconstructed with the Vendorians. InUniverse they are seen as this, but after a few appearances the audience can see that they are yet another example of [[AliensAreBastards asshole aliens]] who are acting mysterious for a lark.
121	[[/folder]]
122
123	[[folder:Real Life]]
124	* Some scientists theorize that the reason we haven't found any signs of alien life is that we're limited by the assumption that it would be anything like Earth life. Rather, aliens, if they exist, could be so 'alien' that we wouldn't even be able to recognize them by comparison to anything familiar if we did encounter them.
