->''"You already have a pet. He's an Arco-flagellant combat cyborg. He's seven feet tall, and eats 30 pounds of raw flesh a day. You named him 'Skippy'."''
-->-- '''[[http://exterminatusnow.co.uk/2004-05-28/comic/a-little-blasphemy-never-hurt-anybody/yipee-for-skippy/ Eastwood]]''', ''Webcomic/ExterminatusNow''

A character keeps as a pet what would normally be considered (and the same species may be in every other instance) a bloodthirsty monster. Such a creature [[FluffyTheTerrible may be given a deceptive name]]. A person with such a pet may be a FluffyTamer, if not TheBeastMaster. May be a TeamPet.

[[folder:Anime & Manga]]
* In ''Manga/{{Tokko}}'', Kureha keeps a small pet phantom in her jacket pocket.
* In ''VideoGame/{{Utawarerumono}}'' the [[FluffyTamer child of the village]] adopts and raises the orphaned child of the tiger god that had been menacing the village. [[BewareTheNiceOnes And rides it into battle.]]

* There's a Creator/MartyFeldman sketch in which he visits the vet with a large creature in a basket. Of course it ends up eating everyone and their pets in the waiting room.

[[folder:Comic Books]]
* ''Comicbook/TheTransformersIDW'' have featured Sunstreaker's pet Insecticon, [[FluffytheTerrible Bob]].
** Later on there's an [[InvertedTrope inversion]] with Thundercracker (Ex-Decepticon gone native) and Buster (an ordinary puppy).
* ''ComicBook/{{Bone}}'': Smiley Bone adopts a Rat Creature and names him Bartleby.
* ''ComicBook/BlackMoonChronicles'': Pilou takes a dragon egg and decides to hatch it so he can raise the baby dragon. This makes sense, since his origin story shows that he himself was [[RaisedByWolves raised by dragons]].

[[folder:Fan Works]]
* In FanFic/TheMansionverse, the Ghost Host has a thing for… shall we say, ''unusual'' pets, ranging from [[http://haunted-mansion-fandom.wikia.com/wiki/DAV_CA_035 a man-eating bat called Attila]] to [[http://haunted-mansion-fandom.wikia.com/wiki/PHU_DA_005 an equally-dangerous octopus called Octavius]]. On a less dangerous note, he also had an ''elephant'' as a pet. (In ''Louisiana.'') Finally, he [[https://scroogemacduck.deviantart.com/art/The-Ghost-Host-s-First-Tour-of-Disneyland-703399670 really wants]] to adopt the ''Matterhorn Bobsleds'' ride's Yeti, though the Imagineers won't let him.
* In FanFic/TheFall, [[ZeroNoTsukaima Louise]] eventually adopts a [[FalloutNewVegas Night Stalker pup]]. A genetically spliced abomination cross of a rattlesnake and coyote.

[[folder:Films -- Animated]]
* Stitch from ''Disney/LiloAndStitch'', who is actually supposed to be one of the most dangerous alien experiments created by Dr. Jumba Jookiba.
* Toothless from ''WesternAnimation/HowToTrainYourDragon''. Despite his name, Toothless actually ''does'' have teeth. Retractable ones.

[[folder:Films -- Live-Action]]
* In ''Film/ReturnOfTheJedi'', the Rancor Keeper sobs over the corpse of the Rancor that Luke killed in self-defense.
* In ''Film/AdeleHasntHadHerDinnerYet'', Baron von Kratzmar grew a huge carnivorous plant Adele. He treats her as his pet, calling her very affectionately "Adelka" and speaking very softly with her. He grew her with one purpose only, though -- to get revenge [[spoiler:on his former biology professor.]]
* ''Film/LakePlacid'': It turns out that the old lady living on the lake has been keeping the giant crocodile as a pet for years, occasionally feeding it her livestock. And by the end [[spoiler:she's still looking after the baby crocodiles left behind after mama croc has been captured.]]

* Robin Goodfellow in the ''Literature/CalLeandros'' series is followed home from the Metropolitan Museum by an undead, mummified cat. He decides to keep her, and names her Salome. While this may not seem the most horrifying of pets, she does manage to kill his neighbor's Great Dane and leave it on Robin's pillow as a gift.
* In the ''Literature/HarryPotter'' series, Hagrid kept a pet [[GiantSpider Acromantula]] as a student, and hasn't really broken out of the habit by the time of the books (and likely, never will). He seems to have an innate natural rapport with such creatures, and always seems surprised that other people have trouble dealing with them.
* ''Literature/PercyJacksonAndTheOlympians'' Quintus [[spoiler: AKA Daedalus]] has a hellhound, a hummer sized shaggy killing machine that appear to mortals as poodles (miniature or full sized is unsaid), named Mrs. O'Leary. [[BigFriendlyDog She is actually quite nice]]. Quintus later gives her to Percy.
* ''Literature/TheReynardCycle'': Tiecelin's flock of [[MixAndMatchCritters Shrike Chimera]]. They're utterly loyal to him, and generally leave his allies be, but they are unsettling bird creatures with human faces, and they feed primarily on human corpses. Understandably, most people are uncomfortable around them.
* ''Literature/ASongOfIceAndFire'':
** The Stark children, including [[HeroicBastard Jon Snow]], each get a direwolf pup, who -- while they quickly become capable of tearing out throats -- are [[UndyingLoyalty very loyal to their master and family]] and [[NobleWolf generally don't attack people]] [[EvilDetectingDog unless they're a threat]], with the exception of [[FluffyTheTerrible Shaggydog]], who is extremely vicious and feral.
** Daenerys Targaryen has three dragons who hatched from petrified eggs. They grow fast and soon begin to terrify even her because she is unable to tame them completely. Dragons were thought to be extinct and she doesn't know how to train them properly.
* Mouse from ''Literature/TheDresdenFiles'' is a dog that can take on a van, or TheFairFolk, or he gets shot, and shakes it off. He's great with kids. When [[spoiler:Harry's daughter]] Maggie says that there used to be a monster under her bed until Mouse [[BuffySpeak slayerized]] it, Harry isn't sure whether she's joking or not.
* ''Literature/{{Boojumverse}}''. The protagonist of "Mongoose" has a pet 'cheshire', a small friendly EldritchAbomination with MoreTeethThanTheOsmondFamily used for hunting inter-dimensional horrors. [[spoiler:At the end of the story, someone speculates that a cheshire is a tamed and artificially-stunted Bandersnatch, the unstoppable EldritchAbomination that's at the top of the food chain.]]

[[folder:Live-Action TV]]
* ''Series/TheAddamsFamily'' has a pet carnivorous plant named Cleopatra, which is [[ManEatingPlant a bit different than]] your normal Venus Flytrap.
* ''Series/GameOfThrones'':
** The Stark children each get a direwolf pup that is soon capable of ripping out throats, as warned by Lord Eddard. Robb even becomes infamous among his enemies for taking his into battle. Fortunately, the wolves [[UndyingLoyalty are very loyal to their masters and family]] and generally [[NobleWolf don't attack]] without good reason. They do become aggressive if [[EvilDetectingDog there really is a good reason]], but their owners tend to ignore these warnings. Shaggydog is the wildest of the litter and ''really'' doesn't like being chained in a kennel, justified in that his owner and trainer is a six-year-old boy who has been rendered slightly unstable due to his entire life collapsing around him.
** Daenerys' dragons are also this, as they grow fast and they begin to frighten even her.
** Played with, with the Bastard's Girls. They're all regular domestic dogs, but they've been bred to be vicious and have a taste for human flesh.
* ''Series/TheMunsters'' has Spot, a pet dragon that lives in a secret room under the staircase.

* In Myth/GreekMythology, Hades had Cerberus, a massive, three-headed dog with a serpent tail and a mane of snakes.

[[folder:Tabletop Games]]
* Often happens to druids and, to a lesser extent, rangers in ''TabletopGame/DungeonsAndDragons'' 3.0 and 3.5. At higher levels, you can keep huge and dangerous beasts such as [[BearsAreBadNews dire bears]], [[PantheraAwesome tigers]], or [[EverythingsEvenWorseWithSharks sharks]] as your animal companion.

[[folder:Video Games]]
* ''Videogame/HalfLife2'' has Lamarr, a debeaked [[GoddamnBats headcrab]] named after HedyLamarr.
* ''Videogame/DwarfFortress'' allows for [[OurDragonsAreDifferent pet dragons]], hydras and [[SeaMonster sea serpents]], amongst other things.
* In ''VideoGame/DisgaeaHourOfDarkness'' one demon child has zombies as pets. Etna apparently had pet zombies as a child as well. The child's zombie was one of his own creation, complete with one of the most potent ingredients possible... [[spoiler: a horse weiner. ''[[RefugeInAudacity That you can steal for yourself.]]'']]
* ''VideoGame/{{Fallout 3}}'':
** A few Yao Guai (LightningBruiser mutant black bears) are tamed by scavengers.
** Moira's computer records mention her experiments with domesticating mole rats, and according to her they made good pets, as long as they were declawed, defanged, and lobotomized. (A couple of pet mole rats can be found in a shack in ''VideoGame/FalloutNewVegas''.)
* ''VideoGame/Fallout4'' comes up with several options:
** Two perks (Wasteland Whisperer and Animal Friend) allow the player character to tame any hostile creature or animal below their own level. The beast will then follow the Sole Survivor around until killed or left behind during an area transit. Higher perk levels unlock additional abilities like inciting the target to attack or giving it specific commands. The list of tamable critters includes pretty much everything the Wasteland has to offer, up to and including [[BearsAreBadNews Yao Guai]], [[ScaryScorpions Radscorpions]] and, yes, [[TheDreaded Deathclaws]].
** The ''Wasteland Workshop'' DLC allows for the construction of a wide variety of cages to catch an equally wide variety of monsters, including the ones mentioned above. Combined with a [[MindControlDevice Beta Wave Emitter]] they can be turned docile and used as a potentially extremely powerful defence force for player-owned settlements.
** Played with when it comes to Kat and Gus, [[ABoyAndHisX a young girl and her huge sentry bot]] who can be met roaming the Commonwealth in a random encounter. Sentry bots may not be monsters in the traditional sense, but since every single one of them is basically a BossInMookClothing, the trope applies regardless.
* In ''VideoGame/DragonQuestMonsters'' (Pokemon game play with the Dragon Quest bestiary), your main character allies himself with all of the monsters who you fought in all of the VideoGame/DragonQuest [=RPGs=], from little Drakee to huge Dragons.
%%* ''VideoGame/MetroidPrime'':
%% ** The games make occasional reference to SpacePirates with pet Metroids. It tends to end badly.
%% ** Samus gets a baby metroid for a pet at the end of ''Metroid 2''. This ends rather badly with RoaringRampageOfRevenge and HeroicSacrifice.
* ''VideoGame/{{Mabinogi}}'' has a wide assortment of buyable pets, some of them things like venomous snakes or {{giant spider}}s.
* ''VideoGame/{{Torchlight}}'' and the ''VideoGame/{{FATE}}'' series have ordinary pets, but they [[SuperMode turn into]] [[OneWingedAngel powerful monsters]] when [[PowerUpFood fed fish]].
* A crazy man you meet in the sewers in ''VideoGame/BaldursGate II'' has a carrion crawler, a seven-foot long flesh-eating grub, as a pet. Or friend. Hard to tell.
* ''VideoGame/WorldOfWarcraft'':
** Hunter class allows the player to tame a beast mob and keep them as a pet. This can include anything from cats and wolves to the Warcraft equivalents of crocodiles, zombie bears, and tyrannosaurus rexes. And that's just for starters. With the appropriate talents, you can tame even more interesting creatures.
** The Forsaken domesticate massive spiders.
* ''VideoGame/GuildWars'' allows Rangers to tame a number of dangerous beasts, ranging from tigers to bears to spiders the size of a large dog.
* Olaf, one of the vikings from ''VideoGame/TheLostVikings'' suggest keeping as a pet one of the dinosaurs found in {{Prehistoria}}, as he thinks they are "kinda cute".
* ''VideoGame/{{Vindictus}}'''s Tieve was friends with the giant spider that climbed the bell tower and was killed by the heroes in the prologue. While not technically a pet, it was kept to protect the town, and Tieve could talk to and understand the beast.
* ''VideoGame/RagnarokOnline'' has several tameable monsters. They don't do anything but hop around and talk when their [[LevelUpAtIntimacy5 intimacy reaches 'Loyal']]. Besides the cute {{Mascot}} monsters like Poring, Drops, and Poporing you can also befriend the suicidal undead ghosts of virgins and other undead monsters, demons, orcs, and half-human creatures. Another odd pet is Alice, a humanoid maid with a broom that doesn't seem to mind being nothing more than the player character's eye candy.
* In ''VideoGame/SkiesOfArcadia'', Alfonso calls Antonio 1 and 2 his pets. Since they resemble armored bulls, he probably doesn't pet them.
* The Dark Brotherhood in ''VideoGame/TheElderScrollsVSkyrim'' has a pet frostbite spider named Lis; killing it earns you the same penalty as attacking one of the other members (i.e., being suspended from the group). You also fight a crazy mage named Hamelyn who has a bunch of pet skeevers during a Thieves Guild mission.
* Muffet of ''VideoGame/{{Undertale}}'' has a pet giant, freakish spider/cupcake fusion with a voracious appetite, which seems appropriate given her love for her fellow spiders and for baking.
* Shayne from ''VideoGame/{{Battleborn}}'' treats [[EldritchAbomination Aurox]] like he's some sort of pet much to the djinn's chagrin.

[[folder:Visual Novels]]
* ''Deus Machina VisualNovel/{{Demonbane}}'': Al Azif keeps a freaking ''shoggoth'' as a pet. Its name is Dunsany, and she primarily uses it as a water bed. The fact that she can call upon the powers of the [[EldritchAbomination Great Old Ones]] probably goes a long way toward explaining why it never rebels.

[[folder:Web Comics]]
* Zomzom the undead RentAZilla in the webcomic ''Webcomic/{{Megatokyo}}'' that is shrunk and kept as a pet.
* Though we don't actually get to see it, in ''Webcomic/SluggyFreelance'' the Demon King's pet [[http://beta.sluggy.com/daily.php?date=041123 appears to be one of these]].
* The Verres family from ''Webcomic/ElGoonishShive'' have a cat with hedgehog spines as a pet. And it seems SternTeacher (among other things...) Mr. Raven also has one.
* In addition to Skippy (page quote), Virus from ''Webcomic/ExterminatusNow'' has Blasphemy, a [[SonicTheHedgehog chao]] which has modded itself with daemon DNA.
* ''Webcomic/TheOrderOfTheStick'' has Xykon keeping an unknown creature deep in the shadows. We have no idea the nature of this beast, as it has been eternally kept in shadow. We do know that it is ungodly powerful, [[DarkIsNotEvil and actually rather nice]].

[[folder: Web Animation]]
* WebAnimation/ADayWithBowserJr: Iggy Koopa owns a pet Chain Chomp, who is as tender as he is deadly. [[spoiler: Just ask some of the members of the Mario Fan Club.]]

[[folder:Web Original]]
* ''Wiki/SCPFoundation'':
** [[http://www.scp-wiki.net/scp-040 SCP-040 ("Evolution's Child")]]. Instances of SCP-040-1 are essentially this trope. They are created by SCP-040, a little girl that can cause mutations in animals to the point of creating entire new species, all of which behave like domestic house pets and are completely loyal to her.
** [[http://www.scp-wiki.net/scp-1550 SCP-1550 ("Dr. Wondertainment's Custom-Pets™")]]. They were designed to live in any environment that normal animals can live in and be pets to the children who live there.
* In ''Literature/VoidDomain'', Arachne in her spider form is one of these. Out of her spider form, she's just a regular monstrosity.

[[folder:Western Animation]]
* In ''WesternAnimation/SupermanTheAnimatedSeries'', Bizarro gets a horrifying three-mouthed beast as a pet, which bites him constantly. Of course, being an [[GoneHorriblyWrong imperfect clone]] of Superman, he [[NighInvulnerable can't be hurt by it]] and is in fact amused by its attempts, and he treats the monster like a dog (even calls it "[[MythologyGag Krypto]]").
* Joker gets a pair of hyenas in ''WesternAnimation/BatmanTheAnimatedSeries''. They seem perfectly tame except for one occasion where they hadn't been fed recently.
** ''WesternAnimation/TheBatman'' introduces the hyenas again and gives them an origin story (an EgomaniacHunter gave them to Joker as payment for a job). Egregiously, he intended them to be attack animals, but not only do they immediately cuddle up to him, they love Catwoman and take commands from Harley Quinn.
* ''WesternAnimation/TheLegendOfKorra'' features [[CanisMajor Naga]], Korra's tame [[MixAndMatchCritters polar bear dog.]] The ''only'' tame polar bear dog.
* [[MythologyGag Referenced]] in ''WesternAnimation/LegionOfSuperHeroes'' with Drax's PhantomZone pets, which look like two larger versions of the same creature, but ''with full Kryptonian powers''.
* ''WesternAnimation/SpongeBobSquarePants'': Puffy Fluffy. When [=SpongeBob=] leaves it alone, it transforms into an EldritchAbomination and tries to eat him and Gary.
* ''WesternAnimation/{{Animaniacs}}'': Dot's 'pet' is kept in a tiny box that grows three times larger into some horrendous abomination. Rarely the same creature twice.
* ''WesternAnimation/TeenTitans'': Beast Boy adopts one of Killer Moth's monster moth larvae as a pet, and names it Silky. Ownership switches to Starfire after she had to take care of it for awhile.
* In ''WesternAnimation/TheSmurfs'' episode "Reckless Smurfs", Sassette brings home an oversized frog called a grumper to be her pet while she was [[EverybodyMustGetStoned under the influence of Gargamel's Daredevil Dust]].
* In the ''WesternAnimation/WanderOverYonder'' episode "The Pet", Wander discovers a black spider-like monster with a pair of large red lips on an abandoned ship in space, where it's implied to have killed the crew. Wander doesn't realize its desire to do the same to him until the end, then when he does he anonymously gives it to [[CardCarryingVillain Lord Hater]].
* The HEAT team from WesternAnimation/GodzillaTheSeries essentially have a pet ''Godzilla'', although for Nick he's more of an adopted son.
