->''"That's no ordinary rabbit! That's the most foul, cruel, and bad-tempered rodent you ever set eyes on!"''
--> --'''Tim the Enchanter''', ''MontyPythonAndTheHolyGrail''

It's small. It's fluffy. [[WhatMeasureIsANonCute It's adorable]]. And if you get on its bad side, your death will be painful, but swift.

Related to but distinct from FluffyTheTerrible, as well as being sort of a subtrope to OurMonstersAreWeird, the KillerRabbit is any monster that's [[PintsizedPowerhouse far more dangerous than it looks.]] Maybe it's strong for its size, poisonous on a massive level, has flesh-rending pointy bits that aren't readily apparent, or can just [[OneWingedAngel turn into something far more dangerous]]. Either way, it can make a person wary of [[PickOnSomeoneYourOwnSize picking on small, defenseless animals]], much like the OldMaster can make a person more eager to respect their elders.

This trope takes its name from the "Dread Killer Rabbit of Caerbannog" in ''MontyPythonAndTheHolyGrail'', which seems to be a completely ordinary bunny rabbit, with the notably unusual ability to leap through the air at high speed and tear out people's throats.

This creature is also known as a "VorpalBunny", a name which comes from the monster of that name in the original ''{{Wizardry}}'' game from 1981, possibly inspired by the Monty Python movie and is named after "The Vorpal Blade", a fictional sword used to decapitate the titular creature in the LewisCarroll poem "Jabberwocky". The name also spread (via ''DungeonsAndDragons'') to other games such as ''Quest for Glory'' and ''UltimaOnline''.

There's [[TruthInTelevision enough truth behind this]] that one of the first things many children are taught is "Don't try to play with any animal until you know it's friendly." (Another lesson, learned later in life by many, sometimes ''too'' late, is: "Animals can become ''un''friendly ''pretty damn fast''".)

Specific types of Killer Rabbits include [[GirlScoutsAreEvil Evil Girl Scouts]]. {{Ridiculously Cute Critter}}s that are [[SugarApocalypse secretly evil]]. ''Civilizations'' that are more dangerous than they look are {{Superweapon Surprise}}s. Killer Rabbits are the most notable subversion of WhatMeasureIsANonCute, which is pervasive enough for everyone to assume that cute animals are friendly.

This trope is pervasive enough that if any of the FiveRaces in games seems to be cute and harmless, they would by definition have to be occasional Killer Rabbits to make them viable to play.

Compare HappyFunBall, BewareTheNiceOnes, TheCatfish and CuteButCacophonic.

Contrast LevelFiveOnix, HolyHandGrenade (which is often the most effective way to deal with this).

Not to be confused with [[WhatsOperaDoc Kill the Wabbit]].

!!Examples

[[folder: Anime]]
* The Puchuus in ''ExcelSaga''. They resemble adorable teddy bears, but plan to take over Earth by any means necessary, even if it means blowing up major population centers.
** They also have a [[{{Gonk}} piss-ugly]] GameFace when struck and/or in pain, which happen to look like Golgo 13's.
* ''GalaxyAngel'' had a cute little pink hamster that was in fact a bioweapon that is capable of destroying worlds. It also had a penchant for exhibiting GlowingEyesOfDoom and blowing things up with [[BreathWeapon energy blasts from its mouth]].
*Ryo-Ohki from the ''TenchiMuyo'' and company {{anime}} can transform from a cute little bunny-cat thing into a spaceship (or a mecha, depending on which permutation you're watching).
**How about the knife-shooting stuffed animals in Yuzuha's dimension from the second movie? Though that's borderline NightmareFuel as well.
* In ''ParanoiaAgent'', one should stay VERY wary of [[spoiler: the cute, pink, cuddly little plushie Maromi, who is nothing short of a powerful ChessMaster.]]
* ''AzumangaDaioh'' deserves mention for Kamineko, a.k.a. the Biting Cat. While he hasn't ''killed'' anyone, the facade of a cute, irresistible little gray kitty that poor Sakaki can't resist petting hides unearthly speed, a rotten attitude, and [[MoreTeethThanTheOsmondFamily a set of teeth that resemble nothing so much as a bear trap]]. His life's mission seams to be to continually tease and beat up [[TheWoobie poor Sakaki]]. Most cats seem to attack her out of fright, but Kamineko tends to seek her out with [[CatsAreMean malicious intent]].
* Kirara from ''{{Inuyasha}}'' is usually a small and cute kitty, but can transform into a giant, flying, saber-toothed, ''[[IncendiaryExponent flaming]]'' version of itself at will.
* The first episode of ''[[{{Slayers}} Slayers REVOLUTION]]'' introduced Pokota, a small creature entirely suitable as the possible NonHumanSidekick... until he was upgraded (almost immediately) to TheRival status with the town-destroying Dragon Slave spell in its arsenal.
** It's later revealed that his true form is a [[CuteShotaroBoy Cute Shotaro Prince]] of a lost kingdom.
** And let's not forget that the first season gave us Tiiba, who just looked like a chicken but was, in reality, a massively powerful [[OurDemonsAreDifferent Monster]] [[PowerLimiter once he put on his mask.]]
* Japoro from ''Shamanic Princess'', being a ferret-like creature who is also the BattleButler to [[ActionGirl Tiara]].
* Reinforce Zwei and Agito from ''MagicalGirlLyricalNanoha''. Their adorable, six-inch tall stature belies the fact that they were [[RidiculouslyHumanRobots designed to be weapons]] and [[AnIcePerson can encase you in ice]] or [[PlayingWithFire launch giant fireballs]] [[FusionDance even without their masters]].
** And while we're on it? About half the freakin' cast could probably count. That adorable little girl in the frilly dress who hangs around with the talking ferret is ''[[BadassAdorable not to be messed with]]''.
* Yachiru from ''{{Bleach}}'' might be one. While not yet shown in combat, she's a pink-haired [[ReallySevenHundredYearsOld six-year-old seeming]] CheerfulChild who's the vice-captain of a division of {{Blood Knight}}s, was raised from a baby by the baddest BloodKnight of them all, and can scare grown men with her BattleAura.
* The DarkMagicalGirl Rosine from ''{{Berserk}}'' appears as a cute little fairy with butterfly wings, antennae, a furry collar and a butterfly's proboscis on her forehead. But she's also an Apostle. Her proboscis is a WhipSword, the dust of her wings is highly poisonous and if you really piss her off, she'll simply turn into a [[CuteMonsterGirl giant moth moth capable of supersonic speed]] among other things...
* ''FullMetalPanic'''s Bonta-Kun, the series mascot which Sousuke Sagara just so happened to convert into Japan's most adorable little harbringer of destruction. [[http://www.youtube.com/watch?v=QPdV8Qi3Ut4 And God help you]] if you ever have to face more than one...
* CatShitOne (Known in the US as Apocalypse Meow) replaces people with animals depending on their nationality. Americans are rabbits. [[http://www.youtube.com/watch?v=Gr4QBZfjtqs Animated Series Trailer here]]
* Hiyokokko from ''[[TokimekiMemorial Tokimeki Memorial]] ~ Only Love'' definitely qualifies, though she doesn't actually ''kill'' anyone.
* Satchii from ''DennouCoil'' looks like a giant, squishy beanbag chair with a big smiley face that announces its own arrival with a bright, "Me Satchii!" every time. It also fires laser beams that kills kids' digital pets and breaks expensive cybernetic glasses.
* See the ridiculously cute lion and kitty in [[http://www.onemanga.com/Katekyo_Hitman_Reborn/240/16-17/ this picture]] from KatekyoHitmanReborn? Well, they sometimes turn into [[http://www.onemanga.com/Katekyo_Hitman_Reborn/233/17/ this]] and [[http://www.onemanga.com/Katekyo_Hitman_Reborn/195/01/ this]].
* Mappy from ''DragonHalf''. Looks like a cat-sized ball of mousy fluff, but can spontaneously transform into a huge, bear-like hulk. Though admittedly this editor has yet to see it actually attack -- just the threat of bodily harm seems to suffice.
* Played straight when [[HayateTheCombatButler Hayate]] buys Maria-san a cute little bunny as a present. She then sees the bunny in its TV show, where it declares, "I am Muffy! An assassin from hell! Ok! Today, we'll happily cause chaos!"
* ''KyoKaraMaoh'''s tiny, yellow, and bred-by-humans [[RidiculouslyCuteCritter Bearbees]] (which are actually mud with magic on it) will turn into [[{{Gremlins}} fierce, dark colored beasts]] that try to kill you if you get them wet. If they're not wet, hey, they're freaking adorable and cuddly.
** Those are magical counterfit bearbees. Real bearbees are cute, huggable, completely non-dangerous, endangered, and their dung makes high-quality paint.
* Mugetsu from ''{{xxxHolic}}'' is an adorable tube fox who takes to Watanuki and can be seen glomping him, slithering through his clothing, or hanging around his neck - until Watanuki is in danger, at which point he [[spoiler: transforms into a normal Kitsune who can detect evil spirits and produce fire]].
* For a literal example, in {{Digimon}}, Terriermon transforms into a trigger-happy rabbit.
** And of course even earlier in DigimonAdventure: Patamon digivolve into... ''Angemon!''
* ''Kirby: Right Back At Ya!'' features the Devil (or Demon) Frog. Not quite a ''killer'', but instead a mind possessor who infects the victim and forces it to go on a rampage (also increasing its physical capacities by quite a bit). An infected Kirby, due to his normal innocence, merely becomes a mean trickster bent on breaking everything and anything he sees. A (voluntarily) infected Dedede, on the other hand, becomes ''even more evil'' than normally, and comes dangerously close to killing Kirby.
* ''PetShopOfHorrors'' features another literal example in its first episode "Daughter," which involves a rich couple that recently lost their daughter Alice paying a visit to Count D's eponymous shop. Count D sells them a very rare species of rabbit that [[ReplacementGoldfish looks just like Alice]]. Things go well for the couple until the mother concedes to the rabbit-Alice's request for sugar instead of the water and vegetables indicated in the rules of the contract. It goes very badly for the couple VERY quickly. [[spoiler:It turns out that feeding sweets to this rabbit will cause it to "give birth" to (read: get eaten from within by) dozens of flesh-eating killer bunnies that go forth, kill, eat, and "give birth" to more killer bunnies until the town is overrun]].
** And don't forget- the rabbits [[spoiler:eat people]]!

[[folder: Comic Books]]
*In the Marvel Universe, a powerful hero is [[PettingZooPeople Squirrel Girl]], a young woman with [[WhatKindOfLamePowerIsHeartAnyway the powers of squirrel-agility and control]]. Thanos, Dr. Doom, MODOK, and Deadpool, among others, have all (somehow) fallen to her.
** To be fair, her defeat of Dr. Doom and Deadpool were the only ones that weren't in joke comics.
*** As Monkey Joe would say "it's canon fanboy!"
*** The fact that's said by a talking squirrel who breaks the fourth wall sort of deflates it.
*** Squirrel Girl is Marvel's LethalJokeCharacter.
* Also in a Marvel Vein, during Civil War (specifically {{Runaways}} and YoungAvengers crossover) when the Young Avengers arrive to find the Runaways lair, they meet 11 year old Molly Hayes outside. Due to a mix up Molly assumes they are bad guys and 'hides under their car'. Now by 'hide under their car' I mean find a better place to lift the car and throw it at them. Yeah, they were not really expecting that.
**Well before, when Wolverine scared her at the front of a cathedral, the comic cuts from him starting to threaten her to shut her up...to him flying across the street outside.
* In both the animated ''SonicTheHedgehog'' and the Archie comic series, Bunnie Rabbot has brute strength coming from being a cyborg, although you probably won't see her killing anything more objectionable than a few (dozen) robots.
* ''{{Nextwave}}'' features some "Unusual Weapons of Mass Destruction", including the Drop Bears - koala bears trained to kill, which are deployed by throwing them out of an aircraft. "Cuddly widdle bears of DEATH?!"
** This is based on a joke played by Australians on tourists. See the Real Life section below.
* There was a DoctorWhoMagazine [[DoctorWho Fourth Doctor]] comic, "The Star Beast", where the villain was named "Beep the Meep", a [[RidiculouslyCuteCritter wide-eyed alien ball of fluff]] who just happened to be an unrepentant omnicidal bloodthirsty intergalactic war criminal. Beep proved memorable enough that he got two followup strips and an audio drama.
* In TheDCU, there is a {{Rival}} group to the GreenLantern Corps called The Red Lantern Corps, whose rings are powered by rage. One of the members of the Red Lanterns is a cute-looking kitty... and he is just as dangerous as any other member. Don't fall for his "innocent" act...
* ''KnightsOfTheDinnerTable''. There was the 'squirrel as a fifth level' monster from the strip "The Most Dangerous (Small) Game". Also llamas in B.A.'s campaign have horns and gore people.
* ''TwistedToyfareTheater'' usually brings in [[TheScrappy unpopular characters]] in order to gruesomely kill them for a TakeThat. [[StarWars The Ewoks]], however, instead became a race of vicious, psychopathic Killer Rabbits who dismember, kill, and [[ImAHumanitarian eat]] anything that crosses them.

* The child-like alien miners in ''GalaxyQuest'' had surprisingly sharp teeth. Guy, being GenreSavvy, provides a LampshadeHanging about how they may seem cute now but they'll turn out to be nasty and there'll suddenly be tons more... Yep, right on cue. Guy then notes that he hates being right.
* Early in ''Barbarella'', the title character is similarly menaced by a group of dolls whose mouths show very pointy teeth. Later in the movie, she is nearly killed by vicious killer budgies (parakeets).
* The Mogwai in ''{{Gremlins}}'', except the original Gizmo; fluffy and adorable, they are cruel tricksters who eventually turn into hideous ([[GrotesqueCute yet still somewhat cute]]) monsters which go on a deadly rampage. Indeed, every imaginable variant on this trope seems to run through most, if not all, Gremlin folklore.
* Dennis Nedry in ''JurassicPark'' gets killed by a fairly harmless-looking dilophosaurus... after it spits poison in his face, then ambushes him when he tries to get back to his truck.
**It should be noted that dilophosaurs probably [[SomewhereAPaleontologistIsCrying couldn't do that]]. Then again, we really have no way of knowing But they certainly did ''not'' have those nifty-looking frills.
*** No, there is a way to know. Lizards with neck frills have ridiculously complex hyoid (tongue) bones that help support the frill. This is present both in lizards like anoles and in the infamous frilled lizard. Dilophosaurus did not have this.
*** Also, Dilophosaurs were much bigger than the one in the movie. Which is ironic, considering that the diminutive Velociraptors, actually the size of sheep and covered in feathers, were sized up by RuleOfScary. In the movie, the "Velociraptors" looked more like ''Deinonychus'', a big raptor (though related to Velociraptor) found in Montana (Velociraptor is from Asia). A more [[http://upload.wikimedia.org/wikipedia/commons/c/cd/Velociraptor_dinoguy2.jpg realistic raptor]] would've been the ''perfect'' KillerRabbit.
*** And they're fluffy! Fluffy raptors of DEATH!
**** Well, there are small, harmless-near-cute-looking Proscompnagthus in ''Jurassic Park: The Lost World'', whose packs is enough to turn a male, healthy, adult Caucasian (Not that I hate Caucasians) into...
***** Did you find him?
***** ...Just the parts they didn't like.
*''{{Night of the Lepus}},'' a movie about [[AttackOfThe50FootWhatever giant]] [[AttackOfTheKillerWhatever killer rabbits]]. It is [[NightmareRetardant intended as a horror film]].
* The TropeNamer White Rabbit in ''MontyPythonAndTheHolyGrail''. (Ironically Arthur and his knights are warned repeatedly by Tim about the power of the rabbit. They don't listen and he laments how no one listens to him because "it's just a harmless little bunny!")
** "Look at the ''bones''!"
* The gopher in ''{{Caddyshack}}''.
* ''CatsAndDogs'' had their antagonist Mr Tinkles--the cute cat who's also a DiabolicalMasterMind.
* Let's not forget ''{{Screamers}}''. Can I come with you?
* This troper made a film for a high school project that was inspired by the Monty Python killer rabbit with, obviously, a genetically altered killer rabbit as the antagonist. Can be seen in two parts on Youtube. The first part is [[http://www.youtube.com/watch?v=IzzUiEF86qA here]]. Trust me though, it's only for the brave of heart.
* The Vampire Pomeranian in ''{{Blade}}: Trinity'' named Pac-Man.
-->'''Hannibal King:''' You made a goddamn vampire... ''Pomeranian''?!?
* In ''MomAndDadSaveTheWorld'', Dick Nelson encounters a group of cute mushroom-like creatures which appear to be friendly... until he tries to pet one. It opens a huge mouth with sharklike teeth and almost takes off his hand.
* DonnieDarko - the main character sees a demonic rabbit named Frank.
* [[StarWars Ewoks]]. Yes, they're cute. Yes, they're fuzzy and huggable and all that. Yes, they're adorable minature bears. Think about that one. Miniature ''[[EverythingsWorseWithBears bears]]''! With astonishing engineering skill for a neolithic technology, extensive knowledge of sophisticated warfare, and a willingness to kill and eat other sapient beings. Think of them as armed, sapient, and highly sophisticated bipedal giant koalas who regard you as potential food, and you'll start to understand exactly why the Ewoks qualify for this trope.
** Still don't believe us? Go read ''Apocalypse Endor'' (Star Wars Tales 14). [[spoiler: That's right -- Endor is TheEmpire's 'Nam]].
* The titular character in the ''Leprechaun'' series.
* Mom & Dad Save the World! There's a veritable truckload of these in the form of adorable mushrooms!

* ''[[http://www.amazon.com/Tuf-Voyaging-George-R-Martin/dp/1592220045/ref=pd_bbs_sr_1/104-6117255-8583944?ie=UTF8&s=books&qid=1191036129&sr=8-1 The Plague Star]]'', by George R.R. Martin (of ''ASongOfIceAndFire'' fame) featured creatures called "hellkittens." These were much like the Arduin "killkittens," (see below) except with paralytic venom in acidic saliva rather than in hollow claws.
* Another ''literal'' killer rabbit is the Miraj (also rendered Al-Mi'raj, or various other variations on the two) of Islamic poetry. A yellow rabbit with a single large horn, it can kill and eat things much larger than itself. It appears in early editions of ''DungeonsAndDragons'' -- with a third-party company porting it to 3e -- where some of them have PsychicPowers. It also appears in ''DragonQuest'' where, due to the translators apparently flipping coins, it's sometimes called the "bunnicorn".
* Margaret Atwood's ''OryxAndCrake'' includes wolvogs, creatures that look like friendly dogs, but act like aggressive wolves.
**It's worse than that. Wolvogs look like friendly dogs, and when they are not ruthlessly killing other creatures, they ''act'' like friendly dogs. They can go from friendly to homicidal, and back, quickly.
* ''Bunnicula'' has a vampire-like rabbit that Chester ''assumes'' is a killer rabbit, but there's no evidence that he ever actually does any harm whatsoever besides draining vegetables.
* Norska in the ''{{Dragaera}}'' series are carnivorous rabbits that eat dragons.
* In Terry Goodkind's ''Soul Of The Fire'', an embodiment of evil either possesses or impersonates a chicken. Strangely, the main characters are capable of realizing this...which means you have two badasses who rule the known freaking world and who can alternately make people her slave or destroy armies with a wave of his hand ''scared shitless by a goddamn chicken''.
** [[MemeticMutation This was no chicken! This was evil manifest!]]
* In the Robert Heinlein juvenile ''Tunnel in the Sky,'' a group of teenagers on a survival-training exercise are stranded on an Earthlike planet when the wormhole they used to get there malfunctions. One local animal is the "Dopey Joe," a stupid, slow-moving cat-sized reptiloid which appears utterly harmless . . . until the season comes when it, well, swarms.
* [[{{Redwall}} EULALIA!]]
**And that's just the badgers. The other species like hares, mice, otters, squirrels, hedgehogs, and even ''moles'' are also quite capable of fucking up the shit of any vermin that threaten them.
** Although a badger isn't exactly in a KillerRabbit scenario when what it's fighting is a rat.
* [[WatershipDown Gen. Woundwort.]] As opposed to Bigwig, who is One BadAss Rabbit.
* The bunnydogs from ''TheWarAgainstTheChtorr'' series by David Gerrold appear to be the only friendly Chtorrans encountered by the humans. Unfortunately they also [[spoiler:represent humanity's future in the Chtorran ecology: as passive, contented creatures who are [[EatTheDog glad to be eaten]] by higher members of the food chain.]] There are also meeps. A mother rabbit will reject her own young to nurse meeps, who will then suckle her to death. One character darkly theorises that the excessively cute bunnydogs are meant to be the equivilent for humans.
* Mr. Rabbit from ''Rainbows End'' qualifies as "the next bad thing" in the eyes of one expert character. The previous "bad thing" was a plaque worse than bubonic, and the one before that was the nuclear destruction of Chicago. It's never made clear how much rabbit-nature he actually has.
* The political satire ''The Year of the Angry Rabbit'' by Russell Braddon. The rabbits are infected with a highly toxic (to humans) strain of myxomatosis. Rather than trying to wipe them out however, the Australian government is more than happy to possess the most feared biological weapon in the world. Was the inspiration behind the classic BMovie ''{{Night of the Lepus}}''.
* TheEdgeChronicles is covered in TheLostWoods and full of [[CrapsackWorld all manner of horrific animals]] and [[ManEatingPlants plants]], but the effectively undisputed top of the foodchain are Wig-wigs. Small, orange fluffballs that also happen to be pack hunters that can and will kill anything they can reach, no matter how big or strong it is. Their only real weakness is their inability to climb.
* Most of the "Furies" from the StarTrek [[ExpandedUniverse novel series "Invasion"]] resemble demonic creatures (because they're the beings that spawned the legends). A few, however, are fluffy and cute. They're still vicious killers who want their ancestral home back, though.
* Treecats in David Weber's [[{{HonorHarrington}} Honorverse]] are cute, fluffy, six-limbed felinoids who are great with children, wonderful, supportive companions for life who'll be with you through thick and thin...and will turn into fuzzy, flying ''buzz saws'' if they think you're a threat to their kittens or adopted humans.
** Treecats think that enemies come in only two states: those that have been properly dealt with, and those that are still alive.
* In ChinaMieville's [[PerdidoStreetStation The Scar]], the head of Armada's underwater police force is a sadistic dolphin named Bastard John.

*In one episode of ''XenaWarriorPrincess'', sidekick Gabrielle must fend off a vicious attack by what is essentially the Rabbit of Caerbannog.
* The original Basil Brush.
* The Furbie-esque Nubbins in {{Sanctuary}} are a variant of this--they're only dangerous in large groups and when being directly attacked, but their extremely high reproductive rate and lack of predators outside their natural environment make them potentially highly destructive to the ecosystem. Unfortunately, [[spoiler:they're a {{Hive Mind}} far brighter than they seem, and are more than willing to sacrifice individual lives to escape and spread.]]
[[/folder]]

[[folder: Music]]
* Synth-Rock band TheBirthdayMassacre seem quite fond of this trope, as a cartoonish, silhouetted killer rabbit is featured prominently as the band's main logo
* The titular critters in the Frank Hayes filk song ''[[http://www.pairlist.net/pipermail/mid-ohio-filk/2005-October/000102.html Little Fuzzy Animals]]'' are examples of this trope.

* In the the radio show ''OldHarrysGame'', Satan finds the most evil being in the world is a Dolphin. Called Chuckles.

[[folder: Tabletop Games ]]
* The original ''[[http://www.arduin.com Arduin Grimoire]],'' a very early third-party supplement for ''DungeonsAndDragons'', included among its bestiary a creature called the "killkitten". Resembling normal kittens, these beasts were actually cunning pack predators whose hollow claws could inject a paralytic poison. Their normal procedure was to set one of their number as [[SchmuckBait bait to attract a potential victim]] by acting like an injured kitten, while the remainder of the pack lurked, hidden, nearby. When the unsuspecting schmuck picked the "kitten" up, it would paralyze him with its venom, after which the rest of the pack would swarm and eat him.
** Somewhat related, in the 3rd edition of ''DungeonsAndDragons'', due to quirks in the system, a common house cat poses a serious threat to the average first level {{NPC}} and some of the physically weaker first level player characters. Given the large numbers of claws and teeth possessed by the common house cat, they would pose a serious threat to the average {{RealLife}} NPC and player characters.
** Your standard adult domestic housecat in 3.5E DnD is also much more dangerous than one would think-between their bite and claw attacks, cats are entirely capable of fighting and killing entry-level characters.
** Two words: ''Tucker's Kobolds''.
* ''{{Deadlands}}: The Weird West'' features jackalopes, which are evil and carnivorous versions of the infamous "rabbits with antlers" from Wild West folklore. They kill their prey by cursing them with bad luck, then stalking them until they suffer a fatal accident.
* ''{{GURPS}} IOU'' includes lethal versions of rats and squirrels.
* The Unglued expansion set from ''MagicTheGathering'' gave us the Infernal Spawn of Evil, a powerful beast from the darkest pits of hell. [[http://ww2.wizards.com/gatherer/CardDetails.aspx?&id=9779 This is what it looks like]]. Not to be outdone, the Unhinged set introduced its even stronger child, the demon known only as the [[http://ww2.wizards.com/gatherer/CardDetails.aspx?&id=73981 Infernal Spawn of Infernal Spawn of Evil]].
** Then there's that other Unhinged set card, [[http://ww2.wizards.com/Gatherer/CardDetails.aspx?name=when%20fluffy%20bunnies%20attack When Fluffy Bunnies Attack]].
** The ''real'' "killer rabbit" of the Magic world is the ''squirrel'. Some squirrel-themed cards, such as "Deranged Hermit" and "Squirrel Nest" have seen extensive TournamentPlay.
** Also, [[http://ww2.wizards.com/gatherer/CardDetails.aspx?&id=6138 Jackalope Herd]]. A bunch of bunnies with antlers, amazing combat stats for their mana cost, and a drawback (returning to your hand when you play another spell) that can be turned into an advantage fairly easily.
* This troper once participated in a game of ''DungeonsAndDragons'' in which a party of first-level characters was slaughtered by rabbits. Said lapines had +4 attack/damage bonuses against first-level [=PCs=] but were otherwise perfectly normal.
** There's a long-standing semi-joke that an ordinary housecat can destroy a first-level wizard in ''DungeonsAndDragons''. [[http://www.giantitp.com/forums/showthread.php?t=93068 This thread]] over at the ''OrderOfTheStick'' forums didn't make it past the first page before being hijacked by Snuggles the Death Kitty. (Later, Snuggles ascended to [[PhysicalGod godhood]]).
** The 3.5E Monster Manual IV introduced the Skiurid-an evil squirrel from the Plane of Shadow, and generally regarded as one of the worst monsters DnD ever introduced. Then an infamous column on the WizardsOfTheCoast DnD section came along, specifically looking for ways to make Skiurids lethal. The troper can attest that the squirrels are quite capable of bringing even a mid-level party of well-equipped adventurers to their knees.
** The giant shrew, a critter from Basic D&D, looked like a normal-sized grayish rat, yet could do a pretty good VorpalBunny impression on low-level adventurers.
** Quite a few fey arguably qualify-the well known nymph, for example, has one ability you don't hear about too often: if you happen to catch a sight of the nymph naked, she can force you to make a fortitude save or die on the spot. Other kinds of fey are more "harmlessly cute" than the nymph, but tend to have a wide range of powerful magical abilities.
*** Very few fey are harmless. In fact plenty of them will to horrible things to you given the chance.
* ''{{Warhammer 40000}}'', a setting known for a habit of EverythingTryingToKillYou cropping up everywhere, brings us the Catachan Barking Toad: a large, sad-looking amphibian sometimes dubbed the "Ronery Toad". If attacked, hurt or even surprised, it explodes into a cloud of obscenely virulent toxins, killing absolutely everything for miles around and poisoning the earth so that nothing will ever grow there again.
** [[FridgeLogic Which raises the question]] of how Catachan manages to be a jungle planet when it's stuffed to the gills with toads that render acres of land into blasted wasteland if you so much as give them a particularly mean look.
***Because everything else on Catachan is [[DeathWorld just as mean.]]
* Plenty of the weapons in the (coincidentally-named) KillerBunniesAndTheQuestForTheMagicCarrot game fall under this. Included:
** Quite Irascible Diffractable Cheese Balls
**(Bitter-Sweet) Chocolate Covered Anti-Matter Raisins
** Europan Robotic Titanium Termites
* ''Munchkin'' has a level 2 monster that's basically a rabbit with a switchblade, where the Bad Stuff is "you die" (yes, a literal KillerRabbit; not surprising since he's actually Bun-Bun, the {{Sluggy Freelance}} character mentioned below). One time in six, it turns into a level 15 monster, as "That One Rabbit From [[MontyPythonAndTheHolyGrail That One Movie]]", and it's too late to get help.

* An almost literal example from OdinSphere is Prince Cornelius. He looks all cute and stuff, but easily he'll hand you your ass with his [[MegaMan Zero]] like fighting style.
* The slimes from ''DragonQuest''. Most of them actually aren't that dangerous, but given how incredibly adorable and harmless they look, it doesn't take a lot for them to be much more dangerous than they look. [[http://tvtropes.org/pmwiki/pub/images/rocket.jpg Tell me you'd think this could do any harm.]]
* Similarly, the Rabites from the ''Seiken Densetsu'' or ''[[ManaSeries Mana]]'' series, which are sort of [[http://tvtropes.org/pmwiki/pub/images/Rabite_Mana.png blobby killer rabbits]]. Although the yellow ones are little more than a nuisance, even to a small child, some of the other colors really are quite dangerous, especially the [[BonusBoss black ones]].
** The Black Rabite, one of the adorable little creatures mentioned above, with the respective color, is the most dangerous thing in the game. It looks like a small black bunny slipper until it opens a can of whoop-ass on you.
* The Fairy you can recruit in ''{{Romancing SaGa 3}}'' is a very versatile character, good with Spears, and Bows.
* The knife-carrying, explosive and possessed-by-the-souls-of-criminals penguins known as Prinnies from most of the NipponIchi games since ''{{Disgaea}}''. [[spoiler: And as if the regular ones weren't bad enough, the [[OneWingedAngel final ultimate form]] of Overlord Baal, the most powerful BonusBoss in all said games is a prinny as well]].
** '''B'''efore even prinnies, we h'''a'''d Eryngi, cute little mushroom creatures that c'''a'''ll up mushrooms to attack and say 'gii!' a '''l'''ot. One of them actually demands that you kneel down and beg for your lives lest "your blood will rain on me, gii!" I don't need to say who.
** Prince Laharl counts as well. Given that he looks like a perpetually peeved CuteShotaroBoy and doesn't even graze four and a half feet in height, it is very easy to forget that he's powerful enough to destroy ''an entire planet'' on an angry whim.
*** And in ''[[{{Prinny}} Prinny: Can I Really Be the Hero?]]'', [[spoiler:''he'''s a Prinny, too. This is because ''Prinny'' follows the [[MultipleEndings normal ending]] of ''{{Disgaea}}'', while the other ''Disgaea'' games and all games in which Laharl appears as a BonusBoss consider the ''good'' ending to be canon.]]
**** [[spoiler: And closes it, making possible for both normal and good endings to be the real ending.]]
** That's a quirk of the game style--almost every character in your party in ''Disgaea'' looks perfectly cute and harmless, ''anything'' from LittleMissBadass and DoubleAgent Overlord-Wannabe Etna to any random unit such as the [[MoeMoe ever-moe]] archers can be level 9000 and able to take on the rulers of universes while still looking like [[{{Lolicon}} twelve year olds]]. So, basically, in ''Disgaea'' anything, ''anything'' can be a KillerRabbit. Caution is advised while in the Netherworld.
*** This is actually a quirk of NipponIchi games in general. Many of the characters and enemies are simply adorable, but very, very deadly.
* [[LittleBigPlanet Sackboy]]. He's adorable, perpetually happy and silly, and wants to pal around with his friends. He's also a reality altering God who can create whole worlds with pure thought, alter the state of any object, fly, control time, and has a mean right hook.
* The old adventure-game series, ''Legend of Kyrandia'', has the Kyrandian Killer Squirrels. In the third installment, ''Malcolm's Revenge'', there's one on the very first screen--allowing you to produce one of the fastest Game Overs in videogame history, simply by teasing the squirrel twice--at which point it'll leap at your face, kill you, and drag off your corpse to feed its young.
* The Tonberry and all its variations in the ''FinalFantasy'' series. Its first moves are to walk slowly towards one of the heroes, until it gets near enough and it "Doinks" him. ''Then'' you start taking it seriously.
**{{Lampshaded}} [[http://www.newgrounds.com/portal/view/169933 by Legendary Frog]], when Cloud thinks that he can take on the cute little Tonberry, despite the Narrator's warnings telling him that ''this'' would be a good time to use the "Run Away" option.
** Also apropos to this, ''FinalFantasyXI'' features a number of cute-but-deadly monsters, including rabbits, composing families with level tiers reaching up to very high levels in most cases. Rabbits are one of the more powerful mob-families in general, leading to the saying: "No matter how powerful you are, somewhere in the world there is a rabbit that can kick your ass."
*** From the same game, the Tarutaru race are adorably short and cute; with adorable pointed ears and button noses to boot. They're every bit as powerful as any other player race, though, and especially skilled in magic. Of particular note is [[BreakoutCharacter NPC Professor Shantotto]], who flat-out ''scares'' a good number of the heroes and villains in ''{{Dissidia}}''
** Mog from ''FinalFantasyVI'' can do quite a bit of damage with his dances. [[http://img451.imageshack.us/img451/5270/ad1go6.jpg This]] [[http://img451.imageshack.us/img451/2893/ad2nn0.jpg ad]] for the SNES version of the game is a bit of an exaggeration, but just ''a bit''...
** ''FinalFantasyXII'' has several classes of cutesy enemies, including mandragoras, onions, cacti, and some fiends that actually look like rabbits. The cute enemies your party encounters early in the game generally will not attack unless you attack them first, but later versions are more hostile and can inflict lots of nasty status effects. The king of them all is Fury, a cute little boss bunny who lives in the Necrohol of Nabudis.
*** There's also an enemy that's actually called the "Vorpal Bunny."
**Cactuars. They look like cute little cactus people. but they have an attack that can deal 1,000 damage, no matter what. Even worse is that some games have a second version that can do 10,000 damage, more than the normal HP cap, meaning instant death to anything it hits.
** In FinalFantasyV, there's a cave where you are attacked by "nut eaters"- squirrel monsters, who are not very dangerous, having only 1 hit point each... but frequently, you'll run into a "skull eater" instead, which looks identical (except for being black) and who is powerful enough to ''kill'' your whole party! (Ironically, it ''still'' only has one hit point, so if you manage to penetrate its defense, it goes down in one hit.)
** Chocobos can kick some ass too. Not so surprising really, with those big clawed feet.
* The Cuccos in the ''LegendOfZelda'' games are perfectly harmless chickens for the most part. If attacked, although they are clearly being hit and react with distress, they suffer no ill effect. If attacked persistently, the Cucco will begin to hit back, and an endless swarm of other, equally invulnerable Cuccos will come to its aid, pursuing the player and attempting to peck him to death.
** Their chicks are also masters of deception. In ''The Minish Cap'', the bouncing yellow babies with their cute chirping noises appear to be completely harmless. That is, until you turn Minish-sized and enter Anju's house, where about fifteen or twenty chicks will take notice of you and chase you around in an attempt to eat you.
* In ''MortalKombat 3'' (and the ''Ultimate'' version), the characters have special finishing moves called "Animalities" where they turn into animals and attack their opponent. In ''Ultimate'', the character Kitana turns into a white rabbit and then attacks the enemy in some savage manner.
* The creature from [[http://www.youtube.com/watch?v=T4E0e-ZCn14 The Last Guardian]]. This adorable thing that makes you love it just from the trailer also managed to splatter an armored guard against a wall with a swing of its claw.
* The insanely difficult BonusBoss in ''NeverwinterNights2: Mask of the Betrayer'' is a [[http://www.badgerbadgerbadger.com/ giant badger]].
**Badgers are actually incredibly vicious and dangerous, a giant one even moreso.
*** This may be connected to a DND joke where people found a line the badgers monster manual entry highly amusing: "THIS CREATURE CANNOT END ITS RAGE VOLUNTARILY." http://fearthebadger.ytmnd.com/
* The Hares from ''MonsterRancher,'' in a very literal sense. They're {{Glass Cannon}}s who can deal very high amounts of damage. The Pixies are also pretty bad: {{Cute Monster Girl}}s with SquishyWizard powers. They can also breathe enormous sheets of flame, suck you of your LifeEnergy, and ''claw your friggin' eyes out.''
* In the MMORPG ''[[AsheronsCall Asheron's Call]]'', the second most powerful monster in the entire game was the level-666 White Rabbit, nicknamed "Pookie" by players. It was not uncommon for Pookie to slaughter entire parties of high-level characters using spells such as "Bunny Smite".
* In the secret quest of ''DungeonSiege II'', you fight Killer Prairie Dogs.
** In the secret quest of the first game, you fight Killer Chickens.
*Arguably, many {{Pokemon}} would fall under this. Several of the incredibly powerful "legendaries", like Mew and Jirachi, are certainly small and harmless-looking, although many of them (Mew especially) are also relatively harmless. For that matter, many {{Mons}} series critters and cute anime mascots fall into this trope.
** However, in the game, Mew has good stats and can learn every available technique.
** And we can't forget Pikachu itself. Those rosy cheeks pack enough power to kill darn near anything.
** Lets not forget FEAR, a special setup of a level 1 Pokemon that will take out at least 1 of the opponents
*** The only FEAR that can even remotely work against a good player is Swinub, however. I mean, THE WEATHER can remove the threat of a FEAR
*** FEAR only works on non-ghosts. Substitute also ruins it. Probably the thing that discourages it most is entry hazard, though (and Stealth Rock is pretty much omnipotent in any competitive matches). Cleffa is probably the best Endeavor user out there due to Magic Guard that negates those pesky passive damage, though it doesn't get priority and has to rely on weather to do the actual killing.
** Best example: Manaphy. That thing seems so harmless, but when it was recently tested in Over Used, it centralized the game so much that it was banned again. Basically, it is harmless without the rain, but as soon as, say, Kyogre sets up an infinite rainstorm, that thing becomes a little demon!
* ''CommanderKeen 4'' features an enemy that looks like a teeny-tiny green ball that sorta looks like a particularly cute, though living, pet rock. Approach it and a gigantic mouth extends from it, killing you instantly (although if you know what you're doing, you can paralyze it in the split-second that it takes for the mouth to reach you).
** The above is actually described as a plant in the manual. There are actual deadly living rocks in the game, and plenty other creatures that look either goofy or cute, but can kill you with a mere (venomous) touch. Or by breathing fire. Or pushing you into a death trap. Or gobbling you up.
* In the MMORPG ''EverQuest'' there are certain fish considered sacred by a god. A god who sometimes poses as one of the fish. Attack them at your extreme peril.
* ''WorldOfWarcraft'' parodies this trope in a Warlock class quest. After fulfilling the desires of a clearly insane Gnome warlock NPC, he attempts so summon a powerful demon... but gets a giant chicken named "El Pollo Grande" (The Great Chicken) instead which, despite its appearance, isn't much a challenge.
* {{Kirby}} himself. Adorable little pink puffball with a [[ExtremeOmnivore black hole for a stomach]].
** Don't forget Scarfy. Try to have Kirby inhale this cute little dog, and he gets ugly and chases you around until he explodes.
* Pretty much every enemy in ''MapleStory'' falls into this trope. As a rule, the cuter the creature is the faster it will kill you.
** There are tons of high-leveled monsters that would like to object to that, but examples do exist, especially when low-leveled. See: Slime King, Mushmom, (Dark) Yeti and Pepe, and Bob the Snail. Be especially careful with that last one.
** The most recent addition to the Korean version is Pink Bean, a pink, Pikachu-like boss that eats, sleeps, and plants flowers during the first half of the fight, and then starts killing half of your party members off in a single attack.
** Don't forget the Elemental Kittens of Doom (Jr. Cellion, Sakura Cellion, Jr. Lioner, and Jr. Grupin). They act all pathetic when getting beat up and all but they mob like crazy and can spell doom for those who are more than a few levels below their Level 33.
* The Rabbids from ''{{Rayman}}: Raving Rabbids'' aren't quite literal {{Killer Rabbit}}s (their violence tends more towards slapstick AmusingInjuries), but they're still violently insane and insanely violent.
** And they're trying to take over the Earth and television. ''They're succeeding.''
* The Orz from ''StarControl II'' seem relatively harmless: they talk funny, and resemble disembodied heads with tentacles and parrotfish-like faces. But their ships are actually quite powerful. And then the game starts dropping hints that they're [[EldritchAbomination extensions of a sinister extradimensional monster]] and were responsible for the disappearance of the Androsynth... and if you continue to pester them with questions about the Androsynth, the Orz won't hesitate to silence you ''violently''.
* The Memaus in ''Startopia'' are cute little cat-like creatures that wander around the station. They eat litter, and any guests who pet one get a bonus to happiness. The problem is that, if it's been well-fed, it simultaneously infects the petter with a parasite which will transform the guest into a decidedly not cute "Skrasher" which cuts a swathe of destruction and can absorb a terrifying amount of damage before keeling over.
** And if your security can't kill the Skrasher fast enough, it explodes... into ''more Memaus''.
* ''{{Earthbound}}'' brings us the Clumsy Robot, whose combat actions include sweeping up dustbunnies, picking up nuts and bolts that jiggled loose from its body, eating bologna sandwiches, accidentally firing party-devastating beams and missiles while tripping over its own two feet and being completely unkillable by all normal forms of attack. The party eventually has to be bailed out by the Runaway Five... Who simply run in while it's distracted and turn it off.
* [[RatchetAndClank Ratchet]]. Small, fuzzy, and carries around more firepower than even the Pentagon could dream of.
**Also from the second game in the ''RatchetAndClank'' series, we have the Protopets--cute, Tribble like critters that have rows of shark-like teeth, a nasty temperment, and the tendency to eat anything or anyone they encounter. Oh, and they have the reproductive ability of the original Tribbles as well.
* The Precursors from the [[JakAndDaxter Jak and Daxter]] games, the most powerful beings in the universe, are revealed towards the end of Jak 3 to be [[spoiler: Ottsels, just like Daxter]]. Ever wondered why you never saw one?
* In ''EarthwormJim'', there is a part in the level "Down The Tubes" where you ride on top of a huge hamster that can eat pretty much anything.
** The big hamster? That was the least of the harmless-looking things in ''EarthwormJim'' that can beat you to a bloody pulp. On that same level are small red creatures about half the size of Jim that resist gunfire and if he approaches too close, they slam him against the ground. In a later level, a slime-dwelling creature dwells at the bottom of a massive chasm that looks like a little tan balloon with a smile unless you get too close to it. If you do, it will swiftly start to resemble a tyrannosaur. Then, of course, there's quite possibly the reigning king of this trope (screw seniority) Peter Puppy. A little, pink puppy who, if he gets hurt, changes into a massive, purple, spikey monster with lots of teeth and drains a third of your heath as it literally chews you up and spits you out.
* The deadliest monsters in ''ValkyrieProfile'' are neither dragons nor demons. No, the deadliest creatures in the game are... hamsters. [[BossInMookClothing And they will slaughter your party if you don't know how to handle them]]. In the BonusDungeon of both games, there is a possibility that you may fight hamsters right before the BonusBoss. ....it's actually ''worth'' killing the Angel Iseria Queen, BonusBoss of the game, ''10 times'' to receive the [[InfinityPlusOneSword Angel Slayer]] as it may give you a chance to hurt the hamsters.
* Similarly, in another one of tri-Ace's games, ''[=~Star Ocean: Till the End of Time~=]'', the Sooties (little balls of soot with eyes) are by far the most difficult regular monsters you'll ever meet. They're insanely fast and strong, and due to their tiny size are really difficult to hit. Incidentally, the first ''[[StarOcean1 Star Ocean]]'' includes a "Vorpal Bunny" as one of its enemies. Though it does look cutesey, it's also twice the size of a human, so not ''all'' that cute.
* This is pretty much the entire point behind the ''GaiaOnline'' MMO: ''zOMG!''. Yes, that is actually the name. The basic plot is that relatively harmless inanimate objects such as garden gnomes, cotton balls, and cloves of garlic are somehow becoming animated. A literal case of EverythingTryingToKillYou, if you will.
** The result can be best summed up in a promotional poster featuring a musclebound, heavily armored Orc trapped up a tree by a ''Lawn Gnome'', "Cute? Cute never tried to eat your leg."
** Not to mention those damn Cherry Fluffs, toward the beginning. After easily dispatching three other varieties of Fluffs, you might try your luck on one of these pink fluffy whatsits, only to have the entire thing [[ActionBomb blow up in your face.]]
** The Garlic Animated (a chubby garlic bulb with feet and MoeMoe eyes) might be even cuter than the Fluffs (cotton balls with MoeMoe eyes), but its breath weapon is a force to be reckoned with.
** Nobody's even mentioned the fact that Gaia's ''original'' KillerRabbit, Grunny, is now piloting HumongousMecha submarines in the last two areas? For shame, fellow Gaiafen.
** Arguably, Frank. He's effectively a male {{Meganekko}} of the "shy sweet HollywoodNerd" variety. [[spoiler: And he's a MadScientist working with the BigBad to [[EndOfTheWorldAsWeKnowIt destroy Gaia]] ForScience!]]
* ''{{Braid}}'': Killer Rabbits squared. Or cubed. Not only are these rabbits vicious, but they initially disguise themselves as flowers and sound like cats. No matter what you find cute and charming, there's a good chance Braid's rabbits will undermine it.
* Pick a ''FireEmblem'' game. If it's a cute little girl that looks to not belong in a battle, probably looks to be about 10. She's a Dragon, and can eat most enemies faces without ANY worry of being hurt. Otherwise characters like Est (''Shadow Dragons and the Blade of Light''/''Mystery of the Emblem''/''Shadow Dragon'') and Nino (''Fire Emblem'') are MagikarpPower housed and fit this trope too.
** One exception: Mist from ''Path of Radiance''. She looks no more than a petite 13, can't fight until she gets a class change, and then deals substandard damage. Not quite as young or ineffective in ''Radiant Dawn'', but still unimpressive.
*** She's far from ineffective though, although it takes a bit of work and luck, she can be capable of almost soloing whole maps thanks to her high luck.
* The MMO ''LaTale'' has so many of these that a good rule of thumb is "if it looks cute, run like hell." Especially annoying are the Prring {{Palette Swap}}s and Shaggies, which mob you and jump behind you to deliver devastating back attacks.
* [[MahoujinGuruGuru Kukuri]] in ''MagicalBattleArena''. She's a SuperDeformed sorceress that uses hillariously cute spells and out-adorables every other character by miles (which is saying something since this game is filled to the brim with {{Magical Girl}}s), but good grief, she is deadly. Between the strawberry firing Strawberry Snake (read: Machine Gun), the smiling pink Mini-Planet (read: [[GravitySucks Gravity]] Mines), and the cat totem-pole Long Voiced Cat (read: ManaDrain), all of which she can cast nigh-instantaneously, she's a deceptively dangerous fighter in the battlefield.
* Near the end of ''{{Wizardry}} VI: Bane of the Cosmic Forge'', you may run into faeries in the same areas you're routinly facing down dark crusaders, greater demons, elite samurai squads, and mind flayers. The faeries are much more dangerous than any of the enemies just mentioned, and indeed one of the toughest enemy types in the game. Just be glad these unassuming DemonicSpiders don't show up until around the final dungeon.
* ''Perfect World'' has antelope. They look almost harmless compared to the typical werewolf or protoplasmic ooze, but they are both aggressive and equipped with a dangerous {{Mana}} burn.
* ''Every single monster'' in the obscure GameBoy Color RPG ''Li'l Monster'' is like this. Although some of them are meant to be fierce and imposing, every monster in the game is rendered in a cute, SuperDeformed style. Even the final boss, portrayed as a kind of EldritchAbomination, still has a head that's half the size of his body and dewy eyes.
* The Hairy Bulborb from ''{{Pikmin}} 2'' has huge blue eyes, a tubby round body, and is covered all over in incredibly soft-looking white fuzz. It's downright ''cuddly.'' However, as with any enemy in ''Pikmin'' games, if you so much as ''look'' at it wrong, the Pik-carnage ''will'' be endless.
* The Liir from ''SwordOfTheStars'' are a playable example. They look like friendly whales and dolphins, and are, whenever possible, {{Actual Pacifist}}s. However, if you push them to the point that this is no longer possible, it can easily lead to ''bad'' things. The game's resident AbusivePrecursors, the Suul'Ka did this by enslaving the Liir and threatening to pollute their oceans to an uninhabitable state. There are no more Suul'Ka in this sector of the galaxy, and possibly in the universe; the Liir used their talent for biotechnology to wipe them out with a genetically engineered retro-plague.
* You know what rabbits [[AnimalStereotypes stereotypically]] like to eat? Carrots. However, as anyone who has ever played ''MushroomMen'' can attest, this is a ''damn lie.'' They actually enjoy eating tasty little mushroom boys. Take one step toward one of those GreenRocks-possessed, lapine monstrocities, and just ''watch'' how fast you die.
* Mortal Kombat: Shaolin Monks, there is a secret, unlisted move called Unfriendly Rabbit. That thing is MURDEROUS! The enemy just sits there and pets it while you get the hell back, and then, out of nowhere, the little lagomorph suddenly tears INTO the enemy. When it says Fatality, the rabbit POPS out of the enemy's... I think it was stomach, sitting there as if nothing happened. [[NightmareFuel Nightmare Fuel]] if I ever saw it
** And Kung Lao can use a bunny to beat his enemy to death.
* The Rampage Rabbit from ''Summon Night: Swordcraft Story 2''. After you beat it the first time, it trains itself so that it can beat you afterwards, and is aiming to be the most powerful rabbit.
* The original ''PaperMario'' brings us Anti-Guys. So you're in the Shy Guy Toybox, and you've been running around fighting all these Shy Guys. They aren't too hard; there are a ton of different kinds, but most of them have between 7-9 HP and 2-4 attack. Nothing you can't handle. Then you see a Black Shy Guy with a gray mask, who tells you to get away from his treasure chest. You fight him anyway, and he proceeds to kick the stuffing out of you, because he is a Anti-Guy, and has 50HP, and 12 attack. So you learn from your mistake, and give him a Lemon Candy in exchange for his chest. And everything is right with the world. Until Bowser's Castle. You go through most of Bowser's Castle, and you get to a big talking door, who says he won't let you through unless you answer five questions correctly, and if you get three wrong before you get five right, he'll mess you up. So you get three wrong, but figure "What's he gonna do about it? He's just a door." But then, instead of fighting you himself, he releases three Anti-Guys into the room. The Anti-Squad is harder than the final boss and the Bonus Boss, so you almost invariably die in a horrible fashion. These are the only times Anti-Guys are ever encountered, and there is no warning that you are about to get your bum handed to you on a platter made of your friends' bums.
** Good thing the questions are so easy. Still, if you've properly {{Level Grind}}ed, that could make for an interesting challenge... After all, the lone Anti-Guy in Shy Guy's Toybox wasn't ''that'' hard. (Kent C. Koopa was tougher, as he had 70 HP ''and'' a legitimate defense score.
** On the topic of the PaperMario games (first and second), Amayzee Dayzees. Cute, shiny anthropomorphized flowers, have a tendency to just run away from the battle...and when they don't, WATCH OUT!!! 20 HP, '''20 attack''', and 1 defense. Good luck taking one out, as it'll either run before you get the chance, or kill you.
* The Pig Butoh in [[TheWorldEndsWithYou The World Ends With You]]. Usually, pigs are cute, harmless [[PuzzleBoss Puzzle Mooks]]. Then you find the second-to-last of them. Unlike his fellows, he can be simply beaten to death... but can attack. And his attack stat is [[OhCrap five times the final boss']].
* In ''DarkCloud 2'', [[spoiler:Dark Emperor Griffon's true form is that of an adorably cute bunny person]]. Even the protagonists are surprised. But then the boss battle starts, his true skill as a master mage surfaces, and the infinite ''power'' of his CosmicKeystone shines forth. Hint: [[GadgeteerGenius Max]] and [[ActionGirl Monica]] embody the Earth and Moon in their Atlamillia. Their foe wields the ''[[OhCrap Sun]]''.
* One of ''MetalGear 2: Solid Snake'''s most GuideDangIt obstacles is the [[ProductPlacement MSX cartridge]] guarded by '[[spoiler: deadly poisonous]] Zanzibar hamsters'. At this point, Snake's life bar is as long as it can get, and he has shot down a Hind D helicopter, and Metal Gear D's guided missiles only take off about a sixth of his health bar, but ''touching one of the tiny brown rodents causes instant death''. That said, they [[GlassCannon die in one hit]], so once you've worked out the puzzle to lure them from their hiding place you only need to stand in front of the hole and fire.
* ''CaveStory'' has the Mimigas, friendly anthropomorphic rabbits that are your main allies throughout the game. But, give a Mimiga a red flower to eat, and... they enter a "frenzied" state, which means they mutate into horrific, bloodthirsty, mindless monsters that simply kill and kill and kill until they die. Even the weakest Mimiga becomes powerful enough to be an early-game boss in this form. The Mimigas are aware of this power, but only use it as an absolute last resort.
** And then there's an optional late game boss, Ma Pignon, which is a small, smiling blue mushroom. A smiling blue mushroom that begins rocketing around the room hard enough to cause landslides to fall from the ceiling.
* Max from SamAndMaxFreelancePolice mixes this with PsychopathicManchild and AxCrazy to an eeire extent...
* The SNES action-RPG ''The Twisted Tales of Spike [=McFang=]'' features rabbits that will suddenly open their large mouths filled with sharp teeth in order to latch onto the hero. They are called Python Bunnies. This editor only recently got that joke.
* The Nintendo DS game ''TheDarkSpire'' features Killer Rabbits. Ok, bunnies. Close enough. Subversion in that they are not only not that dangerous but are the ''least'' dangerous enemies on any floors they appear.
* ''DwarfFortress'' has carp.
--> '''Dwarf Fortress Wiki''' [T]here is only one thing to do if you come across a river full of carp and you don't want your dwarves to die... Run. Run and never look back.
* The Chichifa from ''StarFlight 2''. You never see a picture of them. But the Humna Humna trade buoy orbiting their homeworld describes them as "A race of highly prolific, small, furry creatures with long, upright ears and puffy tails. Extremely aggressive, they will swarm to any heat source and attack. Recommend caution."
* Baragon in the game ''{{Godzilla}}: Unleashed'' certainly applies...even if he is a giant dinosaur-thing. Sure, he's the smallest monster in the entire game, and he is [[UglyCute adorable in an odd sort of way]], but he's more than able to take down his opponents including the '''biggest''' monster in the game, Biollante.
*In the ''Guild Wars'' Eye Of The North expansion, the player can be lured by a cute little bunny into a small hollow filled with cute little bunnies... that then turn into a LOT of nasty Vaettir with a named boss in their midst.
*Many of the animals in ''[[NetHack NetHack]]''; it is quite easy to be "killed by a kitten, while helpless" early in the game, and easier to be killed by the chickens.
* ''{{Okamiden}}'', a NintendoDS followup to ''{{Okami}}'', stars Chibiterasu, [[SpinOffspring a puppy replacement]] for Amaterasu. Being the main player character in an ActionAdventure game, how couldn't it be a KillerRabbit?
* There's a Killer Rabbit ''terrain'' in ''{{Populous}}.'' Piglet World is a land of pleasant, grassy meadows and flowering trees...and is apparently so deadly that your little piggy people will start dying immediately after leaving their homes.
* If you think about it, the Sparda family in ''DevilMayCry'' is a family of PintsizedPowerhouse [[KillerRabbit Killer Rabbits]] for other demons, [[BossInMookClothing looking a lot like humans]], until they are attacked and [[NoOneCouldSurviveThat survive mortal wounds]] [[JustAFleshWound as if it was nothing]], [[FlashStep dash under their legs]] and [[DeathOfAThousandCuts slice them repeteadly to death]]. And they even can [[OneWingedAngel Devil Trigger]]. Of course, we can't say much about Sparda himself, but most of this is because Dante, Vergil and Nero are WeakButSkilled. Trish and Lucia also could qualify.
** Then there's [[CharlesAtlasSuperpower Lady]]...
* Arguably anyone from the TouhouProject series. If nobody else, Nazrin qualifies, being a mouse youkai.
* ''QuestForGlory IV'' has actual killer rabbits. Then there's the old lady's pet kitty in the first game, if you're a thief. And those pesky antwerps...

[[folder: Web Animation]]
* The [[http://www.newgrounds.com/portal/view/212095 Bunnykill]] web animation series. A liberal exercise in the trope of Killer Rabbitry (and KatanasAreJustBetter).
[[/folder]]

[[folder: Web Comics ]]
* Mr. Boodles, an average looking cat, from Eerie Cuties proved to be this in the November 18th update

* Bun-bun from ''SluggyFreelance'', whom this author is convinced is portrayed by the same bunny with a dye job and his ears let down. He once skeletonized a shark that had the misfortune of attacking him, and went on a holiday-massacring rampage as part of his vendetta against Santa Claus.
** Also in ''Sluggy Freelance'' there's "The Evil", 18 ([[NumberOfTheBeast 6 + 6 + 6]]) "demon kittens" that go on a killing spree if they have not had milk in the last 24 hours. Of course, these kittens are literally the spawn of {{Satan}}. They show up in two story arcs found [[http://www.sluggy.com/daily.php?date=000626 here]] and [[http://www.sluggy.com/daily.php?date=021021 here]].
* Keeping on the killer rabbit theme, Coney from ''KevinAndKell'', the child of a wolf and a fearless rabbit, Coney quickly became the top predator in her family before the age of 1, capable of (for example) eating a turtle right out of its shell while still crawling, and ''not even breaking stride'' recently, she saved her grandmother from a cat at least twice the size of her dad, and had ''reduced it to a pile of bones'' by the time she turned around to see what happened.
** Her dad, Kevin, might count as well. He's three times the size of any other rabbit we've seen in the strip (including his parents and sister) and mostly muscle. (In fact, he used to have a side job as a masked wrestler).
*The superhero FurryComic ''{{Supermegatopia}}'' features a number of characters who are more dangerous than they appear. The [[TheSpeechless mute]] and docile-seeming Zippy the Sloth is able to [[http://www.supermegatopia.com/comics/zippy.php?thisLink=zippy-03.gif defeat hulking supervillain Brute Force with one punch]], while AntiHero Hell Kitty of the Offenders is a bratty little girl... with razor-sharp claws, super-healing, and a hair-trigger temper.
** The creators of ''Supermegatopia'' also spoofed this trope in [[http://www.supermegatopia.com/booty/gallery/gallery.php?thisLink=bushtail.jpg this]] ''WorldOfWarcraft'' fan comic.
** Also, [[http://www.supermegatopia.com/booty/gallery/gallery.php?thisLink=cliffhanger.jpg The Claw]].
* Subverted in an ''ElGoonishShive'' strip with Jeremy, who attacks Sensei Greg... Only to [[http://www.egscomics.com/?date=2002-07-18 run facefirst into a ki forcefield.]] Ow. Of course, it was [[http://www.egscomics.com/?date=2002-05-13 earlier stated]] that Jeremy did have some punch.
** Grace combines this with BewareTheNiceOnes. A normally sweet and cute squirrel-girl who, once angered, destroys a [[WithGreatPowerComesGreatInsanity self-proclaimed]] god.
* In ''SparklingGenerationValkyrieYuuki'', the [[NorseMythology Norse trickster god Loki]] walks the earth in the body of a ''stuffed animal''.
* ''[[EightBitTheater 8-Bit Theatre]]'' featured the diminutive but dreaded camel spider (based on a real-life arachnid, whose threat is greatly exaggerated), which "viciously attacks anything it perceives as a threat, which is anything it can perceive."
*Arguably, the entirety of ''[[http://bunny.frozenreality.co.uk/ Bunny]]'' is based off this trope, particularly Orange Bunny.
*Slim the Jackalope from ''[[http://www.mopsy.com NeverNever]]'' has sixguns. Very tiny sixguns. And he bites. Extremely hard.
* ''SchlockMercenary'' features a species of "cute and cuddly koalazoids" known as the Tausennigan Ob'Enn. The Ob'Enn, despite their small size and disarming appearance, are referred to as the "psycho bears" by every other species in the galaxy, as they have one of the most powerful and advanced interstellar militaries in the galaxy, and are led by a xenocidal doctrine that calls for the destruction of every other species in the galaxy.
* Lepus, the awakened Fiendish rabbit from ''[[http://www.dungeoncrawlinc.com/comic6.html Dungeon Crawl, inc.]]'' As the page's title suggests, he was originally a homage to the original Killer Rabbit (before he became a full-fledged character).
* [[http://bukucomics.com/loserz/index.php?comicID=478 Deadly venomous chipmunks]] in ''{{Loserz}}''!
* In ''{{Adventurers}}!'', the [[http://www.adventurers-comic.com/d/0302.html Devilrabbit]] is mistaken for the mostly harmless Cuterabbit.
* Reynardine, in ''GunnerkriggCourt''. He's apparently a cute little stuffed toy. He's actually a fearsome possessor demon that kills the body of whoever he takes over. He just happens to be stuck in Antimony's toy. For now. An illustrative [[http://www.gunnerkrigg.com/archive_page.php?comicID=407 example]].
* On the website Muse Blog, run far, far away if you see a Hot Pink Bunny. They are out to rule the world, can turn people into zombies, and can survive atomic blasts. This may or may not be where their powers come from.
* The Racconans, in ''TalesOfTheQuestor''. They're cute, fuzzy two foot tall talking raccoons... who turn into lightning-flinging shredding whirling balls of death when backed into a corner. A typical saying in the Questorverse is "there's no such thing as an unarmed Racconan." Alternatively, the Redcaps, who bear a marked resemblance to the little dancing mushrooms from Fantasia, till the needle-sharp claws and fangs come out and they leap into your face. Those bright red "mushroom caps" they wear are actually BLOOD SACS, and they've been known to drain an ox dry of blood in moments....
* The Video Games section paid plenty of attention to GaiaOnline's MMO aspect, but Grunny from the webcomic has yet to be mentioned. It is a predatory green rabbit that also carries [[TheVirus the G-Virus]] and turns its victims into zombies.
* ''CharCole'' gives us [[http://kyrio.deviantart.com/art/CharCole-67-116061624 Maoh]] the [[http://kyrio.deviantart.com/art/CharCole-73-116777367 Magnificent]]. Not ''all'' Mew have pleasant temperments...
* [[spoiler:Dolphins]] in ''TheAdventuresOfDoctorMcNinja''. You could punch out and kill all the gorillas, dinosaurs, giant lumberjacks, ninja, vampires, and ghosts you want, but if you treasure your continued existance, leave the [[spoiler:[[http://drmcninja.com/page.php?pageNum=70&issue=14 dolphins]]]] alone.
* [[HollywoodVoodoo Voo Doo]] Doll in ''The Repository of Dangerous Things''. Little. Funny. Quiet. Won't get in the way. [[http://www.drunkduck.com/The_Repository_of_Dangerous_Things/index.php?p=149502 Does not object when grabbed and carried]]. When [[http://www.drunkduck.com/The_Repository_of_Dangerous_Things/index.php?p=156651 thrown]] around, gets really, ''really'' [[http://www.drunkduck.com/The_Repository_of_Dangerous_Things/index.php?p=156652 pissed off]].
* Coleman of ''Sore Thumbs''. A tiny blue polar bear that served in Iraq alongside its owner. [[http://sorethumbs.keenspot.com/d/20050523.html You've never seen such an adorable terrorist-slaughtering machine]].
* ''{{Digger}}'' and other wombats may look small and chubby, but they spend most of their lives swinging heavy pickaxes, and are, as she once put it, "like biceps with feet." When pressed into battle, Digger has shown herself to be an effective combatant, not only soundly defeated bandits, but also lecturing them on what poor condition their weapons are in.

* ''WatershipDown''. I'm sorry, in case I didn't say that loud enough, WATERSHIP DOWN. If you need this explained, you clearly haven't watched the movie.
*In the ''FostersHomeForImaginaryFriends'' episode "Eddie Monster", "the Champ" at the imaginary friends fighting league is a harmless looking Pikachu-esque rodent... that sprouts huge electrified tentacles when provoked.
*One episode of ''MenInBlack'', in an obvious jab at ''E. T.'', had a cute and cuddly alien... which could transform into a hideous behemoth on a second's notice when hungry, and was preparing to devour the young boy who had "bonded" with him.
* Nibbler of ''{{Futurama}}.'' It's not his fault he's an unstoppable killing machine... who can devour several hundred times his own body weight in a matter of minutes. His entire species are superintelligent warriors working to save the universe, but it's a {{running gag}} in any episode they appear in that they're also adorable and cuddly.
** His very droppings are ''dark matter'' more dense than the material in a neutron star.
*Several of Stitch's "cousins" from ''LiloAndStitchTheSeries''. Let's not forget Stitch himself, a synthetically crafted living war machine... In a cute fuzzy body.
*One of the ''Aesop And Son'' segments from ''RockyAndBullwinkle'' had a wolf attempting to steal the dentures from a sheepdog in order to render him harmless. After actually managing to succeed, he proceeds to attack one of the sheep, immediately getting fought off by one of the sheep since it also has dentures.
* The ''LooneyTunes'' character Slowpoke Rodriguez is Speedy Gonzalez's cousin, and "the slowest mouse een all Mexico," but he knows hypnosis and carries a .45 revolver.
* The Dark Lord Chuckles the Silly Piggy in ''DaveTheBarbarian'', who is a cute little piggy and a dark lord of evil.
* Played rather straight in ''TheGrimAdventuresofBillyandMandy'' when Pud'n wishes for a cute bunny that will love him forever...and it immediately reveals itself to be a [[AxeCrazy psychotic]], [[LoveMakesYouEvil murderous]] nightmare.
** Also, the Happy Huggy Stuffy Bears, adorable stuffed bears that were [[spoiler: created by Eris to sow chaos in the world by hypnotizing their owners to do their bidding. Eris' scheme is undone when one angers Mandy by saying that she'll be the 2nd most powerful in the world, at which point Mandy orders Grim to decapitate all of them.]]
** Subverted with Billy's "son" Jeffy, a huge, hideous spider who's extremely friendly and wants only to be loved.
* The Chubb Chubbs, from the [[http://www.youtube.com/watch?v=wzqi1bfflDg video]] of the same name, are the terror of the galaxy. [[spoiler: They look like a combination of the cutest features of piglets and ducklings...except when they're baring their several rows of shark-like teeth and eating barbarian invaders alive. They also enjoy cuddling and karaoke.]]
* ''{{Catscratch}}'' had an episode which had a duck in it--and Gordon was extremely terrified of said duck because of an incident that happened when he was a kitten (The duck beat the snot out of him with tremendous superhuman strength) but later on Gordon musters up the courage to defeat the duck.
* ''JohnnyTest'' has a cute kitty cat as one of its villains; said kitty cat possesses a cannon that turns people into cats.
* ''TheFairlyOddparents'' played with this trope as well. The Gigglepies are a race of cute little bunny like creatures that are a cross between Care Bears in terms of looks and cuteness and Pokemon in terms that they are apparently collectible. They roam the galaxy, coming in cereal boxes and use their cuteness and mind-controlling rhymes to subjugate the population, force them to buy them in excess and eventually cost the planet its freedom. Of course with the Yugopotamians, who fear anything cute, making the populace afraid of them works just as well. Once they're done looting the planet they destroy it and move on to the next one. "ISN'T THAT CUTE!?"
** "No! It's horrible! And didn't rhyme!"
*[[FanNickname "Cujo"]] the ghost dog in ''DannyPhantom''. A small, playful, super adorable ghost puppy...that can turn into a twenty-foot monster who's aggressive meter is off the charts. "Beware of Dog" signs would be an ''understatement''.
* ''{{Metalocalypse}}'': the band buys an island full of nuclear mutants and converts it into a home for "wayward kitties." The kitties kill everyone on the island.
* Ling Ling from ''DrawnTogether'', like the ''FostersHomeForImaginaryFriends'' example, is an adorable Pikachu-esque rodent...who is also a murderous HeroicSociopath who kills at the drop of a hat (in the beginning of the show anyway). In just the first episode, he brutally kills and devours another house mate because his name is uttered 3 times. This applies to any of the {{Pokemon}} spoofing characters on the show though, as it takes the battling aspect of the series and cranks it up to GrotesqueCute levels.
* ''Ed, Edd, and Eddy'', quoting Johnny- "I told you bunnies would take over the world, Plank!
* In the ''TheLifeAndTimesOfJuniperLee'' episode "Welcome Bat Otter", the titular bat otter looks like an adorable little otter with bat wings. It's threat level is hyped by the antagonist of the episode, the corrupt businessman mummy Skeeter Khommen-Gettit. It turns out it's threat isn't just hype when it ''eats'' Skeeter. The expression on the bat otter's face at the end of the episode hints that its diet isn't limited to evil magical creatures...
* ''BeastWars'' had a ''flower'' that looked harmless, but got its point across to ProudWarriorRaceGuy Dinobot, by nailing him with a spiky seed right where he couldn't reach.
--> '''Dinobot''': From now on I ''shoot'' my dinner salad before I eat it!
* ''"Attack of the Twonkies"'' says it all in ''JimmyNeutron''.
* The "psycho duck" that Penny Proud adopts in one episode of ''TheProudFamily''. It even beat up the Gross Sisters, the neighborhood bullies!
* The Pandemic episodes of ''SouthPark'' feature giant guinea pigs (which were actual guinea pigs filmed and placed into the cartoon), which are repelled by Peruvian pan flute bands. Several of the guinea pigs wear costumes, such as bee, dinosaur, mouse, and pirate costumes.
** Also the Woodland Critters, who seem cute but are actually rapists with satanic powers.
* In the ''EarthwormJim'' animated series, Jim's sidekick [[http://www.geocities.com/TimesSquare/Stadium/8421/puppy1.gif Peter Puppy]] immediately goes OneWingedAngel when he's [[http://www.geocities.com/TimesSquare/Stadium/8421/puppy4.gif pissed off]].
** This also happens in the games -- the levels where he appears consist solely of trying to keep him -- or his puppies, in the sequel -- from getting hurt so he doesn't turn into a horrifying mutant and maul Jim.
* Bugs Bunny: once something means war, there's no stopping him.
* An episode of [=~Eek! The Cat~=] featured a cute seemingly harmless bunny arriving at Eek's family door, as it turns out the bunny is a deranged psychopath who plots to kill Eek's family after they've thrown Eek out.
* ''WallaceAndGromit - The Curse of the Were-Rabbit''
* The Warners in ''{{Animaniacs}}'' three cute "puppy children" who are basically avatars of chaos. And you ''really'' don't want to piss off Wakko.
* Duck Dodgers: In "Pet Peeved", Duck Dodger's selfish demand for a pet results in him adopting "Koo-koo", an energy mutator that happens to look like a cross between a puppy, rabbit, and kitten. It becomes larger, stronger, and uglier as it absorbs eletrical energy. http://www.youtube.com/watch?v=gTtVu9Ik4kQ
* The title character in RikiTikiTavi. Awww...he's so cute and fuzzy....HOLY SHIT LOOK WHAT HE DID TO THAT COBRA!
** However, Riki Tiki Tavi isn't malevolent. He's actually trying to kill the cobras because they're harming the humans, so this is a more traditional example of ReptilesAreAbhorrent and possibly also WhatMeasureIsANonCute *grumbles*.

* [[http://en.wikipedia.org/wiki/Koala#Ecology_and_behaviour Koalas]]. It's not hard to piss them off, especially if you interrupt one of their 19 hours of sleep, and they have huge teeth and claws that can do some real damage when you rile them up. [[LandDownUnder Please stay away from them.]]
** In Australian mythology there's dropbears which are the EvilTwin versions of the koala.
** [[http://en.wikipedia.org/wiki/Wombat#Wombats_and_humans Wombats]] can do a fair amount of damage too - one naturalist ended up with a 2cm deep bite in his leg. Through a gumboot, trousers, and thick socks. And if they get some speed up (40km/hr at maximum, despite being generally slow) they can knock grown men over. This being [[DeathWorld Australia]], their main defence against predators is to hide in a hole and use their cartilage-heavy, armour-plated arse to keep themselves from serious harm.
* Actual rabbits. They aren't ferocious at all, but they do have a nasty tendency to bite unwary fingertips clean off. Also, don't try to pick up a rabbit unless you know what you're doing, their back feet are powerful and their nails are better described as claws. Pick one up with the pointy bits toward you? Expect it to flail around and for you to bleed.
** This troper's rabbit weighs approximately one pound, is adorable and soft, and has given at least ten people scars, most of whom don't believe her when she says [[SchmuckBait don't touch the rabbit]].
** Hard to believe, but rabbits once defeated Napoleon. He made a hunting party for himself and his fellow generals. The gamekeeper bought over 1000 rabbits, which, alas, were tame - and hungry. When they were released they didn't scatter from shooting - rather they all ran towards Napoleon at 55 km/h. They overran the shooting party and forced Napoleon to flee.
* The platypus. "Awww, lookit the cute little mixed-up thing! It's so adorable, it's like a little beaver-duck, let me pet you little beaver-duck and OH MY GOD POISON STINGER! ''MAKE THE HURTING STOP!!!''"
** TwoWords, Cone Snail.
** As in the Cracked article below: "Mother Nature's way of saying "I made this thing out of spare parts, and it can STILL horribly maim you." [[EverythingTryingToKillYou Pretty typical for]] [[DeathWorld Australia]].

** Is it any surprise that two thirds of the entries on the list can be found in Australia?
* The frickin' Swan, not only because it's fiercely territorial, but you can't even explain that you got bit by a f#$^ing Swan. Not to mention their wingbeats are powerful enough to break bones...
** "A swan can break a man's arm, you know" became a running gag in one of the AdrianMole books.
** Their bills _look_ soft, but they're not. They're not.
** All birds, really. Getting bit by any bird hurts like swear words. And if it's close enough to bite you, there's a good chance it will poop on you too.
*** [[http://www.youtube.com/watch?v=PO5ifLzLYiU This Pelican]].
*** You wouldn't think a chicken would have talons, but having one placed on your head at age five will leave you with a different impression of the hateful little things.
**** There's a reason the ancient Romans considered roosters to be warrior animals...
* [[http://youtube.com/watch?v=_E_SxwbotS0 This rabbit.]]
** This Troper's sister had a very vicious pigmy rabbit that ''attacked and killed'' a 2 ft long snake!
* Due to causing of vehicular accidents, the deadliest animal in the USA is the deer. Repeat after me.
** Car crashes aside, there's still a distressing number of people who seem to think deer=Bambi. Come on, what do you think those huge pointy things on the top of its head are ''for''?
** Though they seem to look mostly like large deers, elks are in fact more like FREAKING HUGE DEERS! Though it's difficult to judge their size correctly from a distance, it's highly unlikely to mistake them as cute and fuzzy animals as bulls can reach a height of 2,30m at the shoulder. Weighting up to a tonne and having a tentency to land on your roof in a car crash, accidents with elks often end up deadly for everyone involved. This makes them the deadliest animal in Skandinavia.
* While emus don't fall under the generally accepted category of "cute", they are essentially human sized birds with fluffy feathers and big, expressive eyes. They can also kick you to death in a matter of seconds. Most of those tall, long-legged, flightless birds [[NotSoHarmless aren't that harmless]]. Ostriches are reputed to be able to disembowel a lion.
** And then there's the Cassowary, which is essentially a Velociraptor with a beak, insanely strong legs with claws and an attitude to match. Anyone still wondering where the dinosaurs went?
** This is the reason why this troper always laughs whenever people say that feathered dinosaurs are NightmareRetardant.
*** A cassowary was used in an episode of BatmanTheAnimatedSeries for The Penguin's [[strike: [[LargeHam Aviary Of Doom]]]] [[LampshadeHanging Big Birdhouse]]. Bruce Timm apparently had to first convince the rest of the writers that it really existed.
* Not physically dangerous but the subjects of the website [[http://www.disapprovingrabbits.com/ Disapproving Rabbits]] can cause a severe feeling of inferiority. Especially [[http://www.disapprovingrabbits.com/2008/03/mr-browny-brown.html this one]].
* Wolves. They look like some breeds of dogs, e.g., German shepherds or Siberian huskies; many breeds of dogs are larger and/or more dangerous-looking. But wolves are ''not'' dogs. Dogs are wolves that have been selectively bred for thousands of years to be safe and tractable companions to humans. Wolves have been naturally selected to survive in the wild as apex predators. They are strong and they are fierce. Genetics matters. Even a wolf raised by humans from birth can prove rather . . . unpredictable. Never have anything to do with a wolf you might see in the wild; don't try to get it to fetch a stick, and definitely don't try to pet it. Never go near even a "domesticated" wolf unless its owner is very, very clear it's OK, and even then, with extreme caution.
** Cute or not, most people ''do'' think of wolves as being dangerous. Considering how many have been killed or hopitalized by domesticated dogs, it's safe to say that Fido is more of a KillerRabbit than the [[BigBadassWolf Big Bad(ass) Wolf]].
** For their SIZE, wolves are not that dangerous, rarely attacking humans unless in packs. Dog have much less respect for humans and are much more dangerous if trained on aggression. A bulldog can kill a wolf twise its mass.
** For that matter (see Cracked above), Dingos. They're essentially the Australian equivalent of wolves, [[{{RecycledINSPACE}} in the outback]].
*** Aren't dingos more like feral dogs?
**** No, '''wolves'''.
* The blue-ringed octopus. Not exactly cute, but it definitely wouldn't look very threatening, despite being one of the most poisonous sea creatures known to man. As comedian Billy Connolly says "It wouldn't fit in the palm of your hand, but if this thing's in a bad mood ''you don't make it to the ****** phone!''"
** Maybe not cute, but definitely pretty. It's a golf-ball sized octopus, mostly white, with iridescent blue rings. (Hence the name...) Most of the time they are pretty docile, but if one bites you, you literally have only a few minutes before first aid has to be performed to artificially keep your lungs and heart working or you ''will'' die -- there is no antivenin. And hey, the best part? Even while you are being ventilated and kept alive by machines, you're totally conscious and aware and ''totally paralyzed!'' Good times ...
* Gorillas are quite peaceful and gentle creatures, but cross them and they'll rip your arms off. Seriously. They can do that. All that tree-climbing and knuckle-walking gives them unmatched upper-body strength.
** Personal testimony: [[{{Geoduck}} this troper]] was once at a zoo's gorilla exhibit, which featured a large Plexiglases viewing window. Some human cretins were tapping on the glass, and one of the gorillas finally wandered over and ''idly'' punched the window. The glass held, but the impact sounded like a shotgun blast.
** Also in the [[strike: ape]] primate category, mandrills are silly-looking rainbow-faced [[strike: apes]] monkeys with big red bums and dewy eyes... as well as huge teeth able to tear through your flesh like pizza dough.
** Chimpanzees, the adorably human like ape often cast in popular culture as inconcequencial childlike roles, can also be quite dangerous when provoked, even when domesticated. A recent article featured a woman who was attacked by a 14 year old domesticated chimpanzee who she had known personally who could open doors, dress himself, and even eat at the dinner table..[[TastesLikeDiabetes awww]]. By the time the chimp was subdued, he had [[NightmareFuel literally torn off her face and was]] ''[[NightmareFuel eating her]]''.
*** Interesting factoid : a full grown adult man can, on average, pull about 200-300 pounds' worth on a [[http://en.wikipedia.org/wiki/Dynamometer dynamometer]]. A female chimp once recorded a pull of 1.260 pounds. ''One handed''.
** In fact, pretty every ape species shouldn't be pissed off. Keep a close eye on monkeys too.
*** It may not be wise to piss off one of those goofy-looking hairless apes you find wandering all over the place, while we're on the subject. They're a very short tempered race and of all the mean animals out there [[HumansAreBastards they're in charge]]. They're no nearly as strong as other members of Order ''Primates'', but they're smarter, and unpredictable as hell, especially when [[{{ZergRush}} in large groups]]. An apex ''social'' preditor, whose natural weapon ''is the club''. Any wonder that domestic dispute calls make cops the ''most'' nervous?
** Pretty much all primates seem to share mankind's tendencies towards [[HumansAreBastards being dicks]], but with super strength and huge fangs on top of it.
* Ferrets, minks, weasels, martens, sables and all mustelids in general (which includes the wolverine) are unbelievably strong for their size. They are not afraid to fight back fiercely when threatened by greater predators, despite their cute, fluffy appearance and alleged cowardice, the latter being a completely false UrbanLegend. Don't believe me? [[http://www.youtube.com/watch?v=WGF-pofc-lQ Watch This...]]
* [[http://www.global-greenhouse-warming.com/images/Cassowary_head.jpg The Cassowary]]- sure, they look like something out of a Jurassic Park Marti Gras parade, but they hold the world record for "Most Dangerous Bird". Normally docile, but if they're threatened or cornered they will disembowel you with a single kick of their huge, taloned feet.
** Given their relation to emus and ostriches, this shouldn't come as a surprise.
*** Their deadliness is somewhat overrated, though, given that only one human death has been attributed to them, and that was a lucky shot to the neck on a really dumb teenager.
* The Werebears toys were seemingly adorable teddy bears with reversible heads and paws that would reveal their "nasty" face when turned inside out.
* Black bears. Arguably the cutest of the bears with their docile, innocent look and sleepy-looking eyes. The Teddy bear was actually based on this bear species. But they are incredibly dangerous and can seriously mess you up if you provoke them. And playing dead doesn't work on them, because if you do they will start to ''eat you.''
** This is because black bears are essentially very large herbivores that evolved to eat a little meat, but would run away from larger predators... all of which happened to go extinct during the last ice age. Since the meat their ancestors generally ate was left behind by other predators, they've learned to eat the dead--or that which is playing dead. On the other hand, those herbivore instincts mean that they can be scared off by anything that makes confident aggressive moves.
*** But just to show you that nature is evil, brown bears (which look similar to the untrained eye) ''did'' evolve as apex predators and should be treated in the exact opposite fashion. Helpful hint--if you're about to go to an area where both bears are possible to meet, learn how to tell them apart.
**** You might also want to carry a gun. And an extra magazine or two. Or three. Thousand.
** This troper personally thinks that polar bears are the cutest bears by far, and their ability to mess people up kinda goes without saying. But... so... ''cute''.
* Polar bears deserve to be a first-level entry here. So cute in the Coke ads, and in zoos - but to a polar bear, all animals that are not polar bears are '''prey'''.
* The panda. Another contender for "cutest bear" (it makes up for not being a bear by being extra cute), a truly ridiculous amount of time, effort and money has gone into saving these fat and lazy animals. Some people might think pandas are vegetarians because they only eat bamboo. They only eat bamboo because it's one of the only things that can't outrun them, being plants. Give an adult 200 pound panda a chance, and it will kill and eat small animals, possibly including children. Fortunately, no one has ever been stupid enough to allow a small child near a hungry panda (and if someone was, this Troper doesn't want to hear about it). Even a lazy panda can be dangerous if you let it. Though this troper loved ''KungFuPanda'' and Po, he ''hates'' real pandas.
** Fun fact: Pandas actually have a carnivore digestive system. Its round face is the result of powerful jaw muscles, which attach from the top of the head to the jaw.
*** This just in: Pandas ''are'' a species of bear, according to genetic analysis.
** Recently, an adult human jumped a fence into a panda cage at a zoo [[WhatAnIdiot and attempted to hug the creature.]] [[http://www.cnn.com/2008/WORLD/asiapcf/11/22/panda.bites.man.china.ap/ He was hospitalized, but survived.]]
* The orca. Despite its cute panda like appearance and entertaining performances at marine parks, the orca lives up to its nickname "killer whale". Basically take a shark, give it a warm blooded body and an intelligent mammmalian brain and a good bit of muscle and you've got an orca. Add to that the orcas' tendency to hunt in packs and they basically take the title of apex predator of the ocean. Though this troper hated ''Free Willy'' given what happened to the whale in RealLife, he ''loves'' real orcas...but stays clear of them all the same.
** Two things to think about--first, "killer whale" is a corruption of "whale killer". Yes, this thing takes down the biggest things [[strike:since the dinosaurs]] ever. Second, it's one vowel away from an almost universally evil fantasy race.
** They also kill sharks. For fun, as near as science can tell.
** Better than that, its species name (''orcinus'') is Latin for "FROM HELL". Everything in the universe is trying to tell you this things will kill you.
** Their name comes also from the Greek ''Orcus''. Meaning ''demon''.
***Interestingly, there have been no documented instances of Orca attacking humans in the water, ever.
**** That's because we're tiny, bony, and have freaky limbs all over the place, instead of proper fins. We are extremely far cry from these creatures' ideal prey. You still may want to think twice whether to stick your hand in one's mouth.
**** ...Or, to quote Gaspode, "what you just said is basically that no humans in the water ever returned to tell the tale".
**** Two things: first, Orcas are ''technically'' dolphins. Dolphins on steroids, but dolphins none the less. Second, Stephan Pastis (creator of ''Pearls Before Swine'') once introduced a killer whale character into the strip. His prey, Johnathan Seal (a seal) was watching a wildlife program on television, where the killer whale on screen partially beached itself so it could reach and chow down on a seal that was basking in the sunlight. Pastis' comment to this strip was "Makes you think twice about volunteering to be kissed by Shamu the next time you're at Sea World."
*** At least they're smart enough to cooperate with humans.
**** And in fact have in the wild in at least one place (alerting whalers to whales in exchange for some choice bits of the carcasses)
*** Which says something interesting, doesn't it? Thanks to their apparent affection for us, and us returning it, Orcas have no natural predators. None. Barring a sudden human interest in killing them for whatever reason, Orcas are the highest species on the food chain that doesn't have nuclear capability.
* This troper believes that ''every "cute" animal'' on Earth is a potential KillerRabbit, due to all animals possessing a 'fight or flight' response. Wild animals are hardwired to consider nearly anything they can't eat a threat (like us). If we deny them the option of 'flight' by trying to cuddle them too much, they can and will 'fight' with everything at their disposal. Even a little mouse can cause significant damage if you let it with its sharp teeth, possibly infecting you with disease in the process.
* A recent article in the London newspaper Metro involved a viper that was rescued from a house in China. The rescuers tried to feed it a live mouse and the mouse ''killed it'' after a half-hour struggle. They could only theorise it had run out of venom during the capture.
* This Troper's friend has a Cockatoo Attack Squad. They not only have sharp pointy bits, but they have SONIC WEAPONRY. THEY WILL FIND YOU. AND THEY WILL END YOU.
* Hamsters. "Aww itsa widdle tribble lookalike fluffyball! C'mere little fluffyball and OWJESUSBLEEDINGFINGER!!" After five years of living with the adorable little buggers, [[AcrossTheStars this troper]] has learned how to deal with them. Do yourselves a favor and don't pick up that adorable little fluffyball unless you're ''sure'' you know what you're doing.
** This editor is particularly wary of the little beasts after one of them ''pissed on him'' while he was cuddling it. Ungrateful bastard.
** Dwarf hamsters (possibly excluding the usually-docile Roborovski breed) are the spawn of Satan. This troper used to work at a pet store and dreaded handling them. Fast, nasty, and quick to bite.
* Arguably, some human beings can fit into this category (humans technically count as animals). See, for instance, [[CuteBruiser Cute Bruiser]].
** There are arguably a few charming children out there who are evil enough, vile enough, and sugary enough to drive any sane person to suicide. This troper's first grade cousin certainly qualifies for all three categories.
** What harm could [[http://en.wikipedia.org/wiki/Manhattan_project a bunch of science geeks]] ''possibly'' do? SoYeah, don't underestimate people who plumb the secrets of the universe for a living.
* [[RidiculouslyCuteCritter Raccoons]], anyone? They look like fuzzy little puppy-cat things with domino masks, but their teeth and claws can kill pets and send people to the emergency room. To top it off, they're the biggest carrier of rabies in North America.
* Dachshunds, aka wiener dogs. They look ''adorable''. They're also bred to go into badger holes and ''eat the badger'', making them cute Killer Rabbit Killers.
* Popular depictions in media notwithstanding, dolphins can be ''very'' dangerous. They use those "cute" pointy faces of theirs like billy clubs to beat up helpless porpoises, baby dolphins, and the occasional ''human'' to death. And that's when they're not trying to ''rape'' them.
** Not only that, but dolphins have been found to kill baby dolphins of other species. ''For no reason.''
** Also, they can kill ''sharks.''
** Oh if you're woundering, not this isn't something males do (like male Loins) ''females will kill their own young for "Shits and giggles"''
*** That's supposed to be spelt "wondering", but that way is [[RuleOfFunny much funnier]].
** Also, as mentioned above, ''orcas'' are a type of dolphin. [[SoYeah Yeah, exactly.]]
***Not to mention in Greek mythology, dolphins used to be pirates. Look up some of the myths of Dionysus.
** They're basically the [[HumansAreBastards humans of the sea, really]]
* The moral of this trope? Don't Let Things Bite You.
** Or maim you!
* Given the sheer number of real life examples in this trope, it's safe to say that ''Earth'' is a killer rabbit ''planet'' - there's always something down here more than capable of making you wish you never came down from space.
** Well, since a big part of nature is "kill or be killed", it's no surprise.
* Also cats. This troper's cat had his front claws removed and he ''still'' puts lots of scratches on me.
** You think EverythingsCuterWithKittens? Imagine a full-grown cat with no restraint. When this troper got her cat when she was kitten, her hands were so badly beaten up that a teacher pulled her asside and asked her what happened.
**It's not uncommon for cats to become ''more'' dangerous after being declawed, because they've lost their main form of defense. Also, declawing is terribly inhumane, but I won't get started on that one.
* Not just animals, but a few ''plants'' out there are pretty nasty:
** Mistletoe and holly- both lovely plants generally associated with holiday romance as well as internal bleeding, cramps, vomiting and diarrhea if eaten. Fun fact: Mistletoe is parasitic.
*** Mistletoe even ''killed a god'' in NorseMythology.
** The seeds of several edible plants, such as apples, cherries, apricots, peaches and plums all contain cyanide-based poisons.
*** Doesn't it take about sixteen million apple seeds to make a lethal dose, though?
** Pineapples are delicious, nutritious, and covered with razor-sharp spikes. Yum yum.
*** And that's without even bringing up [[SuperDimensionFortressMacross Pineapple Salad.]]
** Brazil nuts, coconuts and durians can cause severe injuries or death if they fall on you...and they can fall on you with no warning.
*** And {{House}} taught us that eating too many brazil nuts will mess you up.
*** Don't forget ''Coco de Mer'', the "seeds" of which can weigh as much as 65 pounds.
** Foxglove is a very common decorative flowering plant with the scientific name ''Digitalis purpurea.'' As you might gather, the roots of the Foxglove contain large amounts of digitalis. Not that you are likely to eat it, but if you did, you'd probably have a heart attack and die.
** Oh look! Such nutritious dark berries that looks like cherries! With a sweet taste to top it all! Congratulations! You've just eaten the delicious yet highly toxic berries of the Belladonna, also know as... the Deadly Nightshade!! Better go to the hospital quick if you don't want to die delirious once your nervous system gets permanently disrupted by the extremely potent alkaloids contained in the apparently harmless berries.
** The Monkshood (Also known as Aconite and Wolvesbane) is another decorative flowering plant that contains a ''powerful'' neurotoxin called aconitum in just about all parts of the plant. It's strong enough that you can experience tingling and numbness in hands and arms and cardiac arrythmia just from getting sap from picked leaves on your skin. If for some ''unholy'' reason you ate it, you'd start to feel numbness and gastrointestinal pain in a few minutes, start vomiting profusely within an hour or so, start to lose motor control, your lungs and heart would stop working and then you'd die. There ''are'' reported deaths from accidental aconite poisoning.
* There are some tree frogs, small and rather beatiful. And whether they are alive or dead, merely ''touching'' them with one's bare skin is a bad idea. With [[PoisonedWeapons a tip of blowgun dart]], on the other hand...
* Hippos. This troper once went to a zoo with a hippo tank (Calgary, Alberta) and happened to be in the room when the zookeeper came out and did his talk on them. Two minutes about the tank, two minutes about how they get fed and poop, twenty minutes on ''how they will kill you''. Hippos are highly territorial, aggressive creatures that can indeed run on land, have de-facto armor exceeding that of elephants, and kill more humans than any non-domesticated species of vertebrate out there per year. SteveIrwin 's moment of greatest fear during his career, he once said in an interview, was simply crossing a river at dusk ... in an area known to have hippos.
* Skunks, while they can't kill you, can certainly make you wish they had. That doesn't stop them from being incredibly cute as babies, all the moreso in that they're not afraid of anything.
** Except for Owls. By GOD the Owls. They look so damn wise and cuddly with their giant eyes and noble plumage that we sometimes mistake them for cute things in the forest who hoot at night. Dead wrong. These things are the terrors of the night and even Skunks steer clear of them because of their plumage. it is built to not make a sound when it is in flight, a virtual ninja in the night. You can't spray what you can't see which is why Owls are considered the natural predator of Skunks.
***Also, they're immune to skunk stink.
* Shrews are fuzzy and tiny, which is a recipe for textbook cuteness. Gram for gram, they're also the most voraciously-bloodthirsty predators on the planet, killing prey many times their own size and eating anything that moves. Some of them have venomous saliva as well, so be ''glad'' these things are so little.
* Ever hear of the [[http://en.wikipedia.org/wiki/Honey_badger honey badger]]? Cute, adorable, and capable of killing several creatures much bigger in size, including ''crocodiles''. This troper once saw a video where a honey badger attacked a venomous snake, killing it while sustaining several bites, eating it, and then taking a nap to sleep off the venom. Two hours later, it was up and about like nothing had happened. You do NOT want to mess with these things, EVER.
* Dromaeosaurs (better known as "Raptors" to most people). A group of (mostly) small feathered carnivorous dinosaurs. [[http://upload.wikimedia.org/wikipedia/commons/c/cd/Velociraptor_dinoguy2.jpg Aww, look at how cute it is....]] OH, GOD, IT'S TEARING ME APART WITH ITS CLAWS!!! Good thing they're extinct.
** Heck, modern day ''birds'' certainly apply since they're essentially present-day dinosaurs. You know those cute lil' chickens you see in petting zoos? Those adorable lil' finches and whatnot you see hopping about in the cities? Those fat robins snacking on worms in the backyard? Yeah, you're pretty much looking at the descendants of ancient Theropod dinosaurs (IE: Tyrannosaurus rex, Velociraptor, etc.).
*** They are no less as fearsome as now they sacrificed their size for the ability to fly. Flying raptors. Now imagine if they still hunted in packs and were the size bigger than a sheep. The world is doomed if they existed now.
* Nothing worse than being attacked by a rapid squirrel http://www.foxnews.com/story/0,2933,226760,00.html http://www.metro.co.uk/weird/article.html?in_article_id=2821&in_page_id=2 .
* Killer squirrel eats a live bird! Soon he'll take your nuts! http://www.youtube.com/watch?v=L8pT_8FwmVg&feature=related
* The mongoose. See entry on Rikki Tiki Tavi.
