Maniac Monkeys

Go To
You cannot esc-Ape!
"Monkeys, apes, they all hold stuff with their feet, man! We're talking freaks of nature!"

Apes and monkeys with human-level intelligence, whether artificial or natural, have a recurring tendency to be antagonists in fiction. If the protagonists are humans, they might be suffering an inherent sibling rivalry with the human race, and want to either wipe it out or subdue it. If it's a story with a cast of animals, they might see themselves as "superior" to the other species and try to rule over them. Either way, these monkeys are used as signs that something bad is about to go down.

This trope is distinct from Killer Space Monkey in that these monkeys are usually Super Intelligent Mad Scientists who want to Take Over the World or at least make life difficult for humanity. Another possibility is that they are Genius Bruisers determined to both overpower and Out Gambit their fellow primates. However, often they are just highly aggressive animals that attack humans (which may be Truth in Television for some primate species).

This here is the opposite of Silly Simian. Compare Mischief-Making Monkey, where the trouble the monkey causes is more harmless. Killer Gorilla is a subtrope, as gorillas (and other great apes) are particularly often portrayed as malevolent, due to their great strength and menacing appearance. For the underwater equivalent, see Devious Dolphins. For primates in general being depicted as intelligent, regardless of whether or not they're dangerous, see Intelligent Primate.

  • The Beast Titan, from Attack on Titan. It's 17 meters tall, with Creepily Long Arms, a cruel, brilliant mind, and the ability to turn humans into Titans he can control. Its appearance heralds very bad things. He's the Warchief of Marley's Titan warriors and is rather fond of baseball.
  • Etemon from Digimon Adventure. And Makuramon from Digimon Tamers.
  • The Saiyans from Dragon Ball Z are like this. They are galactic conquerors who can transform into giant apes during the full moon. Their only simian-like characteristic in their normal form is their monkey tails.
  • One of the first monsters seen in The Fruit of Evolution are primates literally called "Clever Monkeys". Not only are they massively more powerful than you'd expect for something that looks like a chimpanzee with a spider monkey's tail, being Level 150, they back it up with high stats, high speed, and powerful attacks, including a Razor Wind kick attack called Guillotine Kick. Their highest stat is actually their intelligence, which allows them to craft (and use!) well-made tools and all kinds of herbal medicines and potions. The Clever Monkeys that Seiichi meets are encountered working under a Kaiser Kong, but it's unclear if that's normal for them.
  • Jojos Bizarre Adventure: Forever from Stardust Crusaders is an orangutan who gained human-level intelligence after acquiring the Stand Strength, and antagonizes Jotaro and his comrades.

  • In So I'm a Spider, So What? 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 the rest will pursue the killer endlessly, 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.
  • Aozaru from The Twelve Kingdoms.
  • Ushio and Tora has two notable examples: The Namahage, a monster who skins women and devours their intestines in an attempt to turn into a human, is revealed to be the transformation of a macaque, who originally wanted to become a human for the sake of his childhood human friend but eventually lost himself in villainy. A later arc has some monstrous babboons lead by a gigantic white elder monkey, who enjoy eating young women. They are a nod to the tale of Shippeitaro.

  • One of the rival teams faced by the Sunny Farm F.C. in Dreamkix had several spider monkeys who'd physically impede their progress, even in blatant displays like covering Roy's eyes and trying to drag George down.

  • The Pak in Known Space are 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 mutates them into Protectors, hyper-intelligent, super-strong sociopaths concerned only with the protection of their progeny. Most of them regard human beings as competitors, and therefore as appropriate targets for genocide.
  • Last and First Men: The sapient monkeys of the Second Men's time are possessed of a large selection of unpleasant traits, including immense avarice, high aggressiveness and bellicosity, a delight in chaos and mischief and an almost sociopathic inability to process the experiences of other beings.

  • One episode of Back at the Barnyard dealt with a space test monkey who pretended to be friendly for awhile before revealing his true colors by somehow intending to take over the entire farm in front of the horrified animals due to his opposable thumbs (which is sort of Fridge Logic as Otis and his friends never had problems with manipulating objects before despite not having opposable thumbs), although it could all be down to playing the entire scenario for comedy.

    Real Life 
  • Nonhuman primates in general are extremely dangerous animals.
    • Baboons are territorial, and they often raid human settlements to steal food. They tend to travel in groups, too.
    • Inverted with gorillas, who are generally docile and peaceful despite being more menacing in their appearance. In the wild, they’re even known to use diplomacy to resolve disputes amongst themselves and other tribes of their species. Harm them or their families, however, and you will soon learn why they have no natural predators. They also may react aggressively to a human chest pounding, smiling, or even looking them in the eye because these all are insults or threats to them. Unfortunately, these are all common things people do in front of them.
      • This silverback took particular offence at a young girl chest pounding, and quickly made the other humans laughing at him realise just who they were dealing with, courtesy of a punch that cracked the thick interior glass pane of his enclosure. Watch the reflections in the window closely, and you’ll see the exact moment everyone realises they made a serious mistake!
    • Chimpanzees are especially dangerous because the common comical and cute portrayal they get in media has led to a mass underestimation of just how violent they can be. People get them as pets for their "cuteness" and have been mauled to death. Seriously, they've been known to torture other chimps, and other animals, to death in the wild. Males fight for and enforce dominance with brutal fights and aggression. They also have been known, as Jane Goodall can tell you, to go to "war", where two troops stay in conflict for a extended period of time until one is entirely wiped out. They also have been caught killing and cannibalizing other chimps, including infant chimps.
    • It's been well documented and established in the animal kingdom that very few predators, despite the danger they pose, 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. 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 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 make them wish they hadn't.
      • 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.
      • 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 Serial Killer... 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.
