->''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 [[FluffyTheTerrible "Skippy"]]''.

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. May be a TeamPet.

[[AC: {{Anime}} & {{Manga}}]]
* In the ''{{Tokko}}'' manga, Kureha keeps a small pet phantom in her jacket pocket.
* In ''{{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 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.

[[AC:{{Comic Books}}]]
* Recent issues of ''TransformersOngoing'' have featured Sunstreaker's pet [[spoiler: Insecticon]], [[FluffytheTerrible Bob]].
* ''ComicBook/{{Bone}}'' - Smiley Bone adopts a Rat Creature and names him Bartleby.

* In ''ReturnOfTheJedi'', the Rancor Keeper sobs over the corpse of the Rancor that Luke killed in self-defense.

* Robin Goodfellow in the ''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.
* ''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.
* In ''ASongOfIceAndFire'' the Stark children each get a dire wolf pup, which quickly become capable of tearing out throats, although they're very loyal to their master and generally don't attack people unless they're a threat. Then there's [[spoiler: Danaerys' dragons.]]
* I wouldn't call Mouse from TheDresdenFiles a monstrosity. At least, not to his face. But how many other dogs do you know that can take on a van, or TheFairFolk, or get shot, and shake it off? Plus, he's great with kids.

[[AC:{{Live-Action TV}}]]
* ''Series/TheAddamsFamily'' had a pet carnivorous plant named Cleopatra, which was [[ManEatingPlant a bit different than]] your normal Venus Flytrap.
* ''Series/TheMunsters'' has Spot, a pet dragon that lived in a secret room under the staircase.

[[AC:{{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.

[[AC:{{Video Games}}]]
* ''Videogame/{{Half-Life 2}}'' has Lamar, a debeaked [[GoddamnBats headcrab]].
* 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.]]'']]
* A few Yao Guai (LightningBruiser mutant black bears) are tamed by scavengers in ''VideoGame/{{Fallout 3}}''.
** 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''.)
* In the game 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 DragonQuest [=RPGs=], from little Drakee to huge Dragons.
* The ''VideoGame/MetroidPrime'' 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''. [[TearJerker This]] [[CrowningMomentOfHeartwarming also]] [[CrowningMomentOfAwesome ends]] [[RoaringRampageOfRevenge rather]] [[HeroicSacrifice badly]].
* ''VideoGame/{{Mabinogi}}'' has a wide assortment of buyable pets, some of them things like venomous snakes or {{giant spider}}s.
* ''VideoGame/{{Torchlight}}'' and the {{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's 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.
** Although maybe not pets in the strictest sense, the Warlock class's demonic minions could count as well.
* 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 ''TheLostVikings'' suggest keeping as a pet one of the dinosaurs found in {{Prehistoria}}, as he thinks they are "kinda cute".
* {{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.
* ''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 ''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.
* ''VisualNovel/DeusMachinaDemonbane'': 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.

* Zombie Godzilla 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 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.
** Not quite: we do know that it is ungodly powerful, [[DarkIsNotEvil and actually rather nice]].

* From the ''SCPFoundation'', 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.

* 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, it [[NighInvulnerable can't hurt him]] and is in fact amused by its attempts, and he treats the monster like a dog (even calls it "[[MythologyGag Krypto]]").
** [[MythologyGag Referenced]] in ''WesternAnimation/LegionOfSuperheroes'' with Drax's PhantomZone pets, which look like two larger versions of the same creature, but ''[[NightmareFuel with full Kryptonian powers]]''.
* 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.
* [[WesternAnimation/SpongeBobSquarePants Puffy Fluffy]]. ''Oh sweet lord''...'''''PUFFY FLUFFY.'''''
* [[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]].
