* ''Franchise/{{Pokemon}}'': Mankey and its evolution, Primeape are characterised for their HairTriggerTemper and violent outbursts, making them notorious for going on a RoaringRampageOfRevenge [[DisproportionateRetribution for minor slights]]. Various renditions of Primeape describe it as being willing to "[[{{Determinator}} chase you down]] '''[[{{Determinator}} forever]]'''" in order to give you a thorough beating if you piss it off.

** It's been well documented and established in the animal kingdom that very few predators, despite the danger they pose, do not usually attack with the intent to draw out their prey's suffering; they simply do so to survive and eat, and most wild animals who attack humans do so out of fear or provocation and don't actively try to kill unless they have to. [[AxCrazy Chimpanzees]] are an exception. As our closest living relatives and one of the most intelligent animals on Earth, they are one of the few animals to understand the concept of [[{{Sadist}} sadism]]. When they attack other animals - even their own kind - it is often premeditated and planned out by them (individually or more chaotically in groups) and they often go out of their way to inflict as much pain as possible. While many victims of their savage attacks, animal or human alike, survive the encounter, chimpanzees will ''[[EyeScream make them]] [[GroinAttack wish]] [[FacialHorror they]] [[AnArmAndALeg hadn't]]''.

* ''WebOriginal/BadTwoSentenceHorror'': Don't open the monkey closet. If you do, evil monkeys will come out and they will [[BuffySpeak eat you to death]] and there will be blood.

* An infamous scene from ''Film/TheOmen'' has [[CreepyChild Damien]] and his mother at a drive-through safari park when a troop of Chacma baboons suddenly go berserk and attack their car. We eventually learn that the baboons, much like an EvilDetectingDog, were responding to Damien's diabolical aura.

** [[https://www.livescience.com/1518-female-chimps-kill-infants.html Passion]] was a female chimpanzee and mother of three infants. She was part of the Kasakela community, studied and pioneered by Dr. Jane Goodall herself (who gave Passion her name), who took note of Passion's savagery. What was so unique about her? She was essentially a chimp female cannibalistic SerialKiller... of ''babies.'' She would lure the parents of chimps away using her daughter Pom as a "femme fatale" sort, before capturing, kidnapping and brutally murdering the offspring, then eating them and giving the remains to her three children. She would also viciously maul or kill any parent who wised up to her tactics and tried to defend their babies. Dr. Goodall even noted that her behaviour was very unnatural for a chimpanzee mothers and she was basically the chimpanzee equivalent of [[https://vocal.media/criminal/female-cannibal-killers-that-will-make-your-skin-crawl Mashilipa]], who had no lasting affection for her own infants, when even her daughter Pom, who helped her commit these atrocities, was [[MamaBear protective of her own son.]]

*** [[https://en.wikipedia.org/wiki/Travis_(chimpanzee) Travis]] was a pet chimpanzee who lived happily and peacefully for 13 years with his human owners. He had been treated like a surrogate son by them and socialized to humans since birth. But one day when he saw his owner's friend holding one of his favorite toys, he savagely mauled her, ripping off her face and hands. His owner tried to stop him by beating him with a shovel and stabbing him with a butcher knife, but he was only stopped when police arrived and shot him.

* ''VideoGame/ListenToTheWind'', for some inexplicable reason, sics a gigantic albino gorilla as one of the bosses, who immediately tries pounding you into a pulp on sight. Despite every single boss before (and after) being humans.

* ''VideoGame/SonicTheHedgehog'':

* In ''LightNovel/SoImASpiderSoWhat'' the Anogratch are a species of aggressive monkey-type monsters. They will attack anything that enters their territory and if a member of a troop is killed [[SuperPersistentPredator the rest will pursue the killer endlessly]], [[RevengeBeforeReason no matter how many die in the pursuit]]. Given their troops can number in the thousands, the Revenge Monkeys are exceptionally dangerous. Their evolved form, the Bagragratch, is a much larger and stronger baboon-type monster but is actually considered less of a threat as it lacks the Vengeance and Wrath skills of the previous form.

* ''Ape and Essence'' by Aldous Huxley uses apes to symbolize the decline and fall of human civilization.
* In ''[[Literature/TheHungerGames Catching Fire]]'', the Hunger Games arena contains genetically-modified killer monkeys with claws and fangs.
* Apes were a common monster in Robert E. Howard's Literature/ConanTheBarbarian stories, being prominent antagonists in "Literature/ThePhoenixOnTheSword", "Literature/IronShadowsInTheMoon", and "Literature/RoguesInTheHouse".

* The Pak, in Larry Niven's ''Literature/KnownSpace'', are [[spoiler:the ancestors of mankind, and are known to Earthly science as ''Homo habilis'']]--young Pak look like somewhat leggy chimpanzees. Their life-cycle is odd, consisting of an animalistic "breeder" phase followed by eating a poisonous root, Tree of Life, that [[PowerUpgradingDeformation mutates]] them into Protectors, hyper-intelligent, super-strong [[EvilOldFolks sociopaths concerned only with the protection of their progeny]]. Most of them regard human beings as competitors--and therefore as appropriate targets for genocide.

* The [[TalkingAnimal talking]] ape Shift serves as an [[TheAntichrist Antichrist]] figure in Creator/CSLewis' ''Literature/TheLastBattle''.

* ''Human'' primates are sometimes considered [[HumansAreTheRealMonsters the most dangerous]] [[HumansAreBastards animals]] [[HumansAreCthulhu on Earth]].[[note]]While people tend to throw a hissy fit and say that "humans aren't monkeys, they're apes!", based on cladistics, [[https://paoloviscardi.com/2011/04/21/apes-are-monkeys-deal-with-it/ apes are monkeys]] (apes are more closely related to [[https://en.wikipedia.org/wiki/Old_World_monkey some monkeys]] than they are to [[https://en.wikipedia.org/wiki/New_World_monkey others]]). This means that, technically, humans ''are'' monkeys.[[/note]] Which makes sense, considering we're the only ones with [[AtomicHate nukes]].

* Koba from ''Film/DawnOfThePlanetOfTheApes'' is a vicious {{sadist}} whose hate causes him to become a genocidal tyrant.

* 1986 film ''Film/{{Link}}'' had a killer chimpanzee butler, rather similar to Ella above.

* A heroic aversion in ''Film/{{Phenomena}}'' with Inga, a chimpanzee of normal intelligence who helps Creator/DonaldPleasence's character Professor Mc Gregor (who is disabled) get around. Inga spends most of the movie as a fairly gentle, amiable primate, but in the film's climax, [[spoiler: after her master has been killed]], she goes on a RoaringRampageOfRevenge and [[spoiler: [[OffWithHisHead decapitates]] the villain with a straight razor.]] This is one of those movies where HumansAreTheRealMonsters.

* Medieval bestiaries [[http://bestiary.ca/beasts/beast148.htm often portrayed them]] as allegories of the devil, and sometimes illustrated [[FaunsAndSatyrs satyrs]] (another source of [[BigRedDevil Satanic imagery]]) to look [[http://www.theoi.com/Thaumasios/SatyroiNesioi.html very ape-like]]. This may be where Lewis got the idea for the above example.

* ''WesternAnimation/Primal2019'': The eponymous ape-men of the episode "Rage of the Ape-Men" are a tribe of savages with a violent culture, holding some kind of fighting tournament in an arena and having a [[PsychoSerum magical serum that enhances size, strength and aggression]]. Their champions are [[KillerGorilla gorilla-like brutes]], but the commoners are smaller monkey-men who ZergRush their opponents.

* ''VideoGame/{{Smite}}'': Hun Batz, the Howler Monkey God of the Mayan pantheon, is a rather sinister monkey driven with vengeance of being humiliated by the Hero Twins. While at first being introduced to replace Sun Wukong, at least Wukong's old kit was meant to be silly, Hun Batz made the kit more sinister as he's more serious in cracking the enemy's skulls wide open. Also, he babbles about TheEndOfTheWorldAsWeKnowIt because [[MayanDoomsday he's Mayan]].

* In Creator/ErinHunter's ''Bamboo Kingdom'' seriese A Troop of Snub-nosed Monkeys kill Root Rising-Tree by knocking the panda into a flooded river leaving his mate Orchid and soon to be mother a widow. Sunset Deepwood forges and alliance with another troop of monkeys lead by Brawnshanks who cause trouble for Rain and Ghost (2 of Root's posthumous children). By the end of the second book, Brawnshanks Troop intended to betray Sunset.
