Maybe it's because they land somewhere in the UncannyValley. Maybe, as with the MonsterClown, it's because writers like subverting the traditionally "cute". Maybe it is a reflection of our savage ancestry. Maybe it's a remnant of our struggle with our differently-evolved cousins. Or maybe it's simply that EverythingsBetterWithMonkeys. Whatever the reason, killer simians make for good alien monsters.

Such extraterrestrial monkeys tend to be brutish killing machines - an intelligent alien ape is usually a subversion.

Yes, we ''know'' this should be called Killer Space Non-Human Primate. No, Earthly villains who happen to be actual apes are not Killer Space Monkeys.

See also ManiacMonkeys. May be a KillerGorilla InSpace. Not to be mistaken with ApesInSpace, who are monkeys that go ''into'' space.


[[folder: Anime and Manga ]]

* The Saiyans from ''Franchise/DragonBall''. They used their power to transform into giant "apes"[[note]] they're referred to as apes, but, having tails, are technically monkeys[[/note]] during the full moon to conquer planets for Frieza. And calling the Saiyans 'monkeys' was a bit of a [[FantasticSlur racial slur]] used by Frieza and his underlings.


[[folder: Comic Books ]]

* A group of intelligent killer space monkeys appear in the ''Magazine/DoctorWhoMagazine'' strip "Sins of the Fathers".
* The Thunes in Mike Baron and Steve Rude's comic book ''ComicBook/{{Nexus}}'' resemble apes. Thunes are an intelligent race, though, and are just as varied morality-wise as humans. The two most prominent Thune castmembers are Nexus's two best friends, Dave and his son Fred, who calls himself Judah.
* Titano from the ''ComicBook/{{Superman}}'' comics, who features in the page image, started life as an ordinary Earth ape. Rocketed into space, he and his ship were bombarded with radiation, which changed him into a giant ape with incredible strength and the ability to emit beams of Kryptonite radiation from his eyes.
* The {{Creator/Marvel}} ''[[ComicBook/TheTransformers Transformers Generation 1]]'' comic had a race of (somewhat) intelligent, vicious cyborg monkeys living in limbo.
* The Gorilla Swarm from ''Comicbook/AstroCity''.


[[folder: Film ]]

* The aliens in ''Film/{{Evolution}}'' start evolving into ape-monsters around the third act of the film as they reach the monkey [[EvolutionaryLevels stage of the evolutionary "ladder"]].
* The Simeons in the ''Franchise/{{Godzilla}}'' series were a race of apes from a planet that was coming close to being sucked into a black hole, deciding to relocate themselves to Earth and building Mechagodzilla to try and conquer the planet in ''Film/GodzillaVsMechagodzilla'' and ''Film/TerrorOfMechagodzilla''.
* One variation is the ''Franchise/PlanetOfTheApes'' franchise, in which the apes are exactly as brutish and nasty as humans. [[spoiler:Also, they're not from space.]]
* [[ProudWarriorRaceGuy Wookiees]] in ''Franchise/StarWars'' are intelligent and heroic, but they're still among the biggest badasses in the galaxy. The Wampa from Hoth is a more traditionally monstrous version.
* The Morlocks in the 2002 adaptation of ''[[Film/TheTimeMachine2002 The Time Machine]]'' were particularly ape-like.


[[folder: Literature ]]

* [[Creator/LarryNiven Larry Niven's]] ''Literature/KnownSpace'' setting has multiple hominids evolved from the Pak, including a whole Literature/{{Ringworld}} full of sentient and non-sentient types. The [[ShoutOut Morlocks]] of Wunderland are also apelike [[UndergroundMonkey cave-dwellers]].
* ''Literature/JohnCarterOfMars'' has the White Apes - gigantic, four-armed Martian primates.


[[folder: Live Action TV ]]

* The Magog from ''Series/{{Andromeda}}''.
* The Ogrons, a race of mercenary grunts often turning up as henchmen to the Daleks in ''Series/DoctorWho''.
* A Doctor Who spin-off novel revealed that the Soviet equivalent of UNIT was called OGRON (Operativnaya Grupo Razvedkoy Obyedinnyonich Natsii- United Nations Surveillance Operations Group); this is regarded as a metafictional in-joke.
* ''Series/{{Firefly}}'': Space monkeys are raised as a possible reason why Kaylee's engine room is so untidy in "Train Job".
* Goldar of ''Series/MightyMorphinPowerRangers'' fame was treated as one (though the original version in ''Series/KyoryuSentaiZyuranger'' was griffin-themed).
* BigBad Pearl Forrester acquired a killer space monkey named Professor Bobo as a henchman in later seasons of ''Series/MysteryScienceTheater3000''. He... wasn't particularly good at his job.
* The Kromaggs, the product of parallel evolution on one of the worlds of ''Series/{{Sliders}}'' with a taste for human eyeballs. In their initial appearance, they were most definitely ape-descended, though later appearances made them more human, with something of a [[LooksLikeOrlok Nosferatu bent]]. (Note that their name comes from "Cro-Magnon", but the actual Cro-Magnons were modern humans.)
* The Mugato from ''Series/StarTrekTheOriginalSeries''.
* ''Series/UltraSeven'': One of [[MonsterOfTheWeek Alien of the Week]] was Goron, a simian MadScientist intent on replacing humanity with a new race of genetically-engineered human-ape hybrids.

* An EasterEgg in Adobe Photoshop [=CS2=] enables you to bring up an alternate about box, (very temporarily) relabeling the program "Adobe Space Monkey".


[[folder: Tabletop Games ]]

* ''TabletopGame/{{Space 1889}}'' High Martians look and act like evil flying monkeys.
* Not so much ''killer'', as their role is more of TheEngineer despite questionable sapience, but ''TabletopGame/{{Warhammer 40000}}'' features the Jokaero, a race of space orangutans. They produce fantastically advanced and powerful weapons which can fire in a variety of modes (heavy flamer, lascannon, melta), and it's possible to have an ''entire army of them'' plus one Inquisitor.
* Another tabletop wargame, ''TabletopGame/AT43'', features the Karmans a race of intelligent apes (actually uplifted Earth gorillas), fond of philosophy and simian-related {{Shout Out}}s. With fondness of {{BFG}}s.
* ''TabletopGame/StarFrontiers'' had the Yazirians as a playable race. They were generally good guys, of the ProudWarriorRaceGuy sort.
* ''TabletopGame/{{Spelljammer}}'' brought the Yazirians back, but renamed them "Hadozee," or "deck apes."
* ''TabletopGame/{{Alternity}}'' had the Weren, who were also [[ProudWarriorRaceGuy Proud Warrior Race Guys.]]
* In ''TabletopGame/EclipsePhase'' police forces on Mars often use genetically modified baboons adapted to the atmosphere, a lot of people are scared of them. In one of the stories an Olympus Ranger character has two of them, one of which smokes and is prone to tearing faces off if he doesn’t get his nicotine fix.

[[folder: Video Games ]]

* ''VideoGame/SystemShock2'' had creepy zombie space lab monkeys. With PsychicPowers (either cryokinesis or pyrokinesis, depending on which kind of monkey).
* ''VideoGame/CityOfHeroes'' has transdimensional psychic monkeys. Which emit toxic gas when defeated.
** And gives you a [[BraggingRightsReward badge]] for [[NeverSayDie "arresting"]] 1000 of them.
* ''Franchise/{{Halo}}'':
** ''{{VideoGame/Halo 2}}'' introduced the Brutes, who are basically gorilla-bears. Gorilla-bears in PoweredArmor who [[GunsAkimbo dual-wield shotguns]]. They become even more ape-like in subsequent games.
** The Grunts also have ape-like features; the Covenant name for them is even "Unggoy", which in Tagalog means "monkey".
** ''VideoGame/HaloReach'' includes the [[http://www.halopedia.org/Gúta Gúta]], essentially tusked lizard monkeys that look kind of like [[AllTrollsAreDifferent trolls]]. However, due to resource constraints, only two appear in the entire game (in "Nightfall"), so some think of them as a GiantSpaceFleaFromNowhere.
* Andross, the BigBad of the ''VideoGame/StarFox'' series is an evil scientist appearing as a giant orangutan head and hands. Most of his underlings are also monkeys and apes.
* The Cosmic Silverback in the ''Dead Ops Arcade'' minigame of ''VideoGame/CallOfDutyBlackOps'', along with the much smaller Space Monkeys in the VideoGame/NaziZombies map ''Ascension''.
* A literal case with General Skun'ka'pe in the third season of the ''SamAndMax'' episodic adventure game.
* The Tarka from ''VideoGame/SwordOfTheStars'' are one part reptile and one part this. In return, they consider us this too.
* The Purr-Lin in the ''VideoGame/{{Turok}}'' series. They are essentially a combination of gorilla and reptile
* Kuja from ''VideoGame/FinalFantasyIX''.
* The FinalBoss of the first ''VideoGame/AeroFighters'', which also appears as a final stage mid-boss in the sequels.
* Despite having four arms, bullymongs from ''VideoGame/{{Borderlands 2}}'' are considered ape analogues.
* The Drengin in ''VideoGame/GalacticCivilizations'' are an AlwaysChaoticEvil race with notably simian features and largely act as the main antagonistic force during the story campaign. And then they get a splinter faction in the Korath Clan, who are even [[OmnicidalManiac worse]].
* ''VideoGame/{{Overwatch}}'' has an entire colony of angry gorillas who live on the moon. One of them succeeded in reaching Earth, but he is, thankfully, a GentleGiant and a scientist (though willing to get violent when he feels he needs to).


[[folder: Western Animation ]]

* ''ComicBook/BuckyOHareAndTheToadWars'': The Betelgeusian Berserker Baboons make up the bulk of S.P.A.C.E.'s SpaceMarine contingent and are more likely than not to go for GoodOldFisticuffs in a setting where FrickinLaserBeams are the standard armament. The first baboon seen is a warp drive engineer, but that doesn't stop him from drop-kicking his way through a bulkhead. However, the baboons are firmly in the heroic camp, though they are TheDreaded to the Toads, and tend towards the BloodKnight side of the spectrum.
** They are also, unlike most examples of this trope, rather small (by human standards, they tower over most of the cast). Willy is a pre-teen human boy, but he can comfortably wear Betelgeusian combat armor with only minor alterations.
* ''WesternAnimation/CaptainSimianAndTheSpaceMonkeys'' had as its main cast a group of ''good guy'' space monkeys. The BigBad, meanwhile, had an evil ''cyborg'' space monkey after them, RHESUS-2.
* An episode of ''WesternAnimation/SupermanTheAnimatedSeries'' has Titano (see Comics section) as Lois Lane's pet monkey (her father was part of NASA at the time.) He eventually lands in Metropolis, starts growing to massive size and runs amok downtown.
* An odd twist on the trope is the ''WesternAnimation/SuperRobotMonkeyTeamHyperforceGo''. They're technically the good guys, but they have no compunction whatsoever against killing their enemies, and being brutal about it.
* Simion from the "WesternAnimation/DextersLaboratory" segment ''Dial M for Monkey'' seeks revenge on the human population for sending him into space and becoming a super ape.


[[folder: Web Comics ]]

* The Lespuko from ''WebComic/ElGoonishShive'' probably count as this. It is a species of alien, its name means "Rock Ape" and it has been shown to be aggressive.


[[folder: Real Life ]]

* There are apes (and other animals) in satellites within Earth's orbit. They are [[ApesInSpace the test subjects in mostly US and former USSR space exploration research.]] They were sent up to monitor the effects of such an environment on living things. They were left up there. Only they are most likely to have been killed instead of mutated into killer space monkeys.
