[[Characters/HarryPotter Return to main.]]

!Hedwig (Gizmo)

Harry's faithful pet snowy owl, and aside from Hagrid, his first friend in the magical world.
* ArtisticLicenseBiology: Hedwig is a female, but only male snowy owls are pure white like she's described as being. Hence, the owls who have played her in the films are actually all male. Hedwig is often described as hooting, but [[http://www.youtube.com/watch?v=hghJ7Aym26M snowy owls bark instead of hoot.]]
* BerserkButton: Being locked in her cage for long periods of time pisses her off. Also, she doesn't like it when Harry is rude to her for whatever reason or when Harry uses another owl for messages.
* CoolPet: A white owl that's also a personal mail carrier.
* EmpathyPet
* HeroicSacrifice: [[spoiler:In the film version of ''Deathly Hallows'', she attacks a Death Eater chasing Harry and Hagrid, then flies into the path of a Killing Curse meant for Harry.]]
** This almost backfires on Harry when [[spoiler:the Death Eater who killed Hedwig identifies Harry as the real one because his pet protected him. Hence why Voldemort immediately attacks him afterwards.]]
* KilledOffForReal: [[spoiler:Along with Mad-Eye Moody during the Battle of the Seven Potters.]]
* MeaningfulName: [[UsefulNotes/PatronSaints St. Hedwig of Silesia]] is the patron saint of orphans.
* NamedAfterSomebodyFamous: Harry named her after someone he read about in ''A History of Magic''.
* {{Pride}}
* RedOniBlueOni: Blue to Pigwidgeon's red.
* SacrificialLion: [[spoiler:Her death marks the end of Harry's childhood, according to WordOfGod.]]
* {{Tsundere}}: Type A.
* UndyingLoyalty: Toward Harry. In the film version of ''Deathly Hallows'', she takes this trope to its zenith when [[spoiler:she tries to save him from the Death Eaters...at the cost of her own life]].


Dumbledore's pet Phoenix. His feathers were used as the cores for both Harry and Voldemort's wands.
* BigDamnHeroes: Comes to Harry's aid in the Chamber of Secrets.
* CoolPet
* {{Familiar}}
* HeroicSacrifice: He takes a Killing Curse for Dumbledore in ''Order of the Phoenix.'' [[spoiler:Since he's a Phoenix, he gets better.]]
* LongBusTrip: It's explicitly spelled out after [[spoiler:Dumbledore's death]] that Fawkes has left Hogwarts forever.
* MeaningfulName: Guy Fawkes is famous for trying to blow up (which would lead to burning) the Houses of Parliament. Phoenixes burn at the end of each 'life.'
* ThePhoenix
* SwissArmyTears: An inherent Phoenix ability.
* UndyingLoyalty: To Dumbledore and by extension Hogwarts. [[spoiler:When Dumbledore dies, he no longer has a reason to stay]].

!Aragog (voice by Creator/JulianGlover)

One of Hagrid's pets, an [[GiantSpider Acromantula]] who lives in the Forbidden Forest with his mate and thousands of children. In ''Chamber of Secrets'', Hagrid, while a student at Hogwarts, cared for him when he was young, and Aragog was accused by Tom Marvolo Riddle of being the creature living in the Chamber of Secrets. Years later, he tells Harry and Ron about the creature living in the titular chamber, then sics his sons and daughters on the two (don't worry, they escape).
* AffablyEvil: Not unfriendly, but pretty darn frightening.
* AndroclesLion: Hagrid cared for Aragog since he hatched, saved his life when the Hogwarts higher-ups might have had him killed, and even arranged to him to meet his mate after he set up shop in the Forbidden Forest. As a result Aragog, in spite of its species being very bloodthirsty and eating humans, cares deeply for Hagrid and has even forbidden his children from harming him. [[spoiler: Unfortunately, Harry and Ron find out that that treatment only extends to Hagrid. Anything else that wanders into Aragog's neck of the woods is fair game.]]
* BackForTheDead: In ''Half-Blood Prince''.
* TheBusCameBack: Not Aragog himself, but his children return during the Battle of Hogwarts, attacking Death Eaters and Hogwarts allies alike.
* CoolPet
* TheDreaded: Acromantulas are feared all across the Wizarding World, and Aragog and his family are no exception.
* GiantSpider
* IOweYouMyLife: Hagrid cared for a young Aragog after he hatched and later got him to safety in the Forbidden Forest following Riddle's accusation. The two maintained contact, which saw Hagrid getting him food and a mate. As such, Aragog forbade his children from ever harming Hagrid. [[spoiler:Unfortunately for Harry and Ron, Aragog's family extends that courtesy ONLY to Hagrid himself.]]
* InterspeciesFriendship: A rare example of Hagrid's affection towards extremely dangerous animals being reciprocated. Aragog and Hagrid have been good friends for over fifty years and when Hagrid is in trouble he gets very concerned for him. This friendship was so strong that Aragog, a member of a species that is considered one of the most dangerous animals on the planet, refused to consume human flesh out of respect for him.
* KeeperOfForbiddenKnowledge
* NonMaliciousMonster: During the Battle of Hogwarts, his children get royally (but understandably) ticked off when the Death Eaters drive them out of the forest, leading them to attack ''everyone'' on the battlefield in an angry frenzy.
* RedHerring
* RoaringRampageOfRevenge: During the Battle of Hogwarts, his children swarm the castle, attacking everyone regardless of their affiliation because the Death Eaters had driven them out of their nest.
* TheScapegoat: For what the Basilisk did. To add further insult to it, Acromantulas hate and fear Basilisks.
* SpidersAreScary
* TalkingAnimal: Being an Acromantula, he and his brood are able to speak.
* ToServeMan: A species trait, though never seen doing so himself. Aragog tells Harry and Ron that he never ate humans, as repayment for Hagrid's kindness. His children, on the other hand...


Voldemort's right-hand pet snake. [[spoiler:She is also one of his horcruxes, and is killed by Neville with the sword of Godric Gryffindor in the Battle of Hogwarts.]]
* AntiMagic: Her venom is resistant to healing magic.
* ArtisticLicence: Nagini is described as being venomous in the books, but portrayed as a reticulated python in the movies, a species of giant constrictors that are non-venomous.
** It's entirely possible, however, that Nagini is from a unique magical species of giant venomous snakes or that she had been altered by Voldemort to better suit his purposes. Nagini's venom definitely has magical properties, judging by how her bites resist healing spells.
* ChekhovsGunman:
* FaceStealer: [[spoiler:She takes Bathilda Bagshot's place upon her death]].
* {{Familiar}}
* [[spoiler: OffWithHerHead]]
* ReptilesAreAbhorrent
* [[RightHandAttackDog Right-Hand Attack Snake]]
* SssssnakeTalk: Speaks parseltongue with her master on occasion.
* [[spoiler:SoulJar]]

!Crookshanks (Crackerjack)

Hermione's pet cat.
* AmplifiedAnimalAptitude: He is able to find Neville's list of common room passwords, understands enough English to understand Ron saying that Scabbers is in his bag, [[spoiler:knows how to freeze the Whomping Willow]], and knows right away that [[spoiler:dog!Sirius is not a dog.]]
* CatsAreMean: Subverted. While he's a bit of a {{JerkAss}} when he first appears, it's because [[spoiler:he knows Scabbers is Wormtail in disguise]].
* DemotedToExtra: He does appear in the film adaptation of ''Prisoner of Azkaban,'' but his "constantly trying to eat Scabbers" subplot is cut out.
* EvilDetectingDog: The first thing we see him do in the books is pounce on Scabbers, [[spoiler:who's actually Peter Pettigrew in disguise.]] Justified, because this is a species trait for Kneazles as a whole.
* [[HalfHumanHybrid Half-Cat Hybrid]]: Half-[[http://harrypotter.wikia.com/wiki/Kneazle Kneazle]], half-cat.
* SpannerInTheWorks: In the film adaptation of ''Order of the Phoenix,'' he breaks the Extendable Ear that Harry, Hermione, Ron, Fred, George, and Ginny are using to eavesdrop on the adults' conversation downstairs.
-->'''Ron:''' Hermione, I hate your cat.
* WhatHappenedToTheMouse: Hermione doesn't take him on the Trio's journey in ''Deathly Hallows''. Crookshanks's last appearance in the series is at the Burrow, a few days before Bill and Fleur's wedding, so it can be assumed he stayed there during the events in the rest of the book.


Ron's pet owl, sent to him by Sirius as a replacement for Scabbers.
* FunSize: Harry mentions that he looks like a very fluffy Snitch.
* {{Keet}}: He is quite hyper.
* RedOniBlueOni: Red to Hedwig's blue.


Hagrid's gigantic boarhound dog.
* BigFriendlyDog
* DeathbringerTheAdorable
* LovableCoward
* WhatHappenedToTheMouse: Whether or not Fang survived the battle of Hogwarts is unknown. As Hagrid showed no signs of mourning over him, it is presumed he is alive, though there has been no actual word on it.

The very old pet owl of the Weasley family.
* ButtMonkey
* CaptainCrash: In the films, at least.
* RunningGag: He faints a lot after delivering letters.

!Mrs. Norris
Argus Filch's RightHandCat. She seems to have a high enough degree of sentience to act as Filch's sidekick. Everyone who's not Filch considers her an annoying spy.
* AmplifiedAnimalAptitude: Mrs. Norris is capable of identifying when students are misbehaving and then running off to get Filch. Filch often speaks to her, calling her "my sweet", although it's not clear to what extent she can actually understand him. Mrs. Norris can apparently communicate back, although we never find out how. Maybe Filch [[SpeaksFluentAnimal understands "cat"]] and they have BilingualDialogue. The usual {{Fanon}} is that they have some kind of psychic connection.
* CatsAreMean: Played straight here.
* FormallyNamedPet
* KickTheDog: The first book indicates that it's the deep desire of many students at Hogwarts to give Mrs. Norris a good kick.
* MoralityPet: To Filch, who sincerely loves her.
* NonHumanSidekick
* RightHandCat
* ShoutOut: Named, by Rowling's own admission, for the character of the same name in Creator/JaneAusten[='s=] ''Literature/MansfieldPark''.

Ginny's pet Pygmy Puff. First introduced in ''Order Of The Phoenix''.
* ExtremeOmnivore: Pygmy Puffs are scavengers and will eat anything. See TrademarkFavoriteFood below.
* RidiculouslyCuteCritter: Pygmy Puffs in general are bred to be small, affectionate, and adorable.
* ShoutOut: To [[Series/StarTrekTheOriginalSeries Tribbles]] of all things. Both are round furry creatures that give off a soft purring sound when content.
* TrademarkFavoriteFood: Boogers.

!Buckbeak / "Witherwings"

Hagrid's pet hippogriff, who was provoked into attacking Malfoy during a Care of Magical Creatures class and set up to be executed by the Committee for the Disposal of Dangerous Creatures. [[spoiler:He's saved by Harry and Hermione and escapes with Sirius instead.]]
* BerserkButton: He doesn't take kindly to [[BullyingADragon Malfoy calling him a "great ugly brute".]]
** It's a Hippogriff thing. Go up and insult one, it'll probably be the last thing you'll ever do.
** Don't attack Harry in front of him, either. He very nearly kills Snape for (seemingly) doing that.
* TheCavalry: Leads the Thestrals of the Forbidden Forest against Voldemort's giants during the final stage of the Battle of Hogwarts.
* CoolHorse
* GiantFlyer: Has a large and formidable wingspan.
* MixAndMatchCritters: Half bird, half horse.
* [[spoiler:OffWithHisHead]]: [[spoiler:Subverted thanks to Harry and Hermione's meddling with the Time-Turner.]]
* OurGryphonsAreDifferent: Specifically, he's a hippogriff.
* {{Pride}}: Enough to demand consent to be ridden (that whole bowing thing). It's a hippogriff trait.

!Norbert ([[spoiler:Norberta]]) the Norwegian Ridgeback Dragon

A dragon that Hagrid illegally wins as a prize ([[spoiler:thanks to a disguised Quirrell)]] and tries to raise as his own. Hagrid tries to keep Norbert a secret, but soon allows Charlie Weasley to take the dragon to a dragon sanctuary in Romania. [[spoiler: It was revealed in ''The Deathly Hallows'' that Norbert is a female.]]
* AdaptationalAttractiveness: A variant. While Norbert is described as being rather ugly and vicious in the books, in the movies he is portrayed as cute and affectionate as a baby.
* MoreDeadlyThanTheMale: How Charlie figured out [[spoiler:that she's a girl]].
* OurDragonsAreDifferent: Was depicted as a classic "Western Dragon" (IE: Four legs, a pair of bat-like wings, and a lizard-esque appearance) in the books (and in older official plush). In the movies, and in newer toys, Norbert's appearance is more based on that of a wyvern (IE: A bipedal reptilian creature with two legs and a pair of bat-like wings.).
* ReptilesAreAbhorrent: While not evil, dragons in general are portrayed as extremely vicious and impossible to domesticate. Of course, Hagrid being [[FluffyTamer Hagrid]], he adores Norbert and doesn't see him as a fire-breathing wild animal.
* [[spoiler:[[SamusIsAGirl Norbert Is A Girl]]]]: [[spoiler:As Charlie reveals in the seventh book.]]
* [[spoiler:TertiarySexualCharacteristics]]: [[spoiler:Female dragons are larger and more aggressive than male dragons.]]

! The Hungarian Horntail

A large, extremely vicious dragon that Harry faces off against during the first task of the Triwizard Tournament. In the books, the Hungarian Horntail is said to be the most dangerous breed. Harry manages to obtain the golden egg the dragon is guarding by flying past her using his Firebolt.
* DeathByAdaptation: Falls to her doom during the movie.
* TheDreaded: Harry is horrified to learn of it's existence and is ready to pass out as the time draws near for him to face it. Even Hagrid admits it's a "nasty piece of work" in the film.
* MamaBear: Dragons are extremely protective of their young in the books/movies. And Harry ends up having to steal an egg from the most dangerous one.
* NonMaliciousMonster: She's technically just trying to protect what she thinks is her own egg. Of course, Hungarian Horntails are extremely vicious by nature to begin with.
* OurDragonsAreDifferent: Is based on a wyvern.
* ReptilesAreAbhorrent: Subverted. They are extremely vicious by nature, but are not evil. And the one in the books/movies is just following her maternal instincts.
* ShoutOut: The design of the Hungarian Horntail in the film was based off of the dragons from the film ''Film/ReignOfFire''. As is it's method of breathing fire[[note]]Specifically, it spits out twin jets of flammable chemicals that ignite upon contact with the air.[[/note]]

! Salazar Slytherin's Basilisk
The legendary Monster of Slytherin, intended to be awoken by Slytherin's heir to purge all the Muggle-borns in Hogwarts. Serves as TheDragon to [[spoiler: Tom Riddle's memory]] in ''Chamber of Secrets'', [[spoiler: where it ultimately dies]].
* AxCrazy: All of its lines are about murder, blood, or killing.
* DeathGlare: Literally. Eye contact with it means instant death.
** TheParalyzer: But only ''direct'' eye contact. Eye contact through a mirror or other reflections paralyzes the victim, which can be reversed.
* ChekovsBoomerang: [[spoiler: Harry uses a fang from the Basilisk to destroy Tom Riddle's diary (one of Voldemort's Horcruxes) in the ''Chamber of Secrets". Years later, when they need to destroy another Horcrux, Ron hits on the idea of doing the same thing and heads down to retrieve fangs from the Basilik's carcass]].
* DragonInChief: To [[spoiler:Riddle's memory]] in the second book. While he was calling the shots, she was the one doing the dirty work.
* TheDreaded: With the exception of roosters and [[spoiler:Tom Riddle]], everyone is terrified of this thing. Even ''Acromantulas'' refuse to speak of her.
* EyeScream: Ends up on the receiving end of this, courtesy of [[spoiler: Fawkes, which allows Harry to properly fight it]].
* ImpaledWithExtremePrejudice: [[spoiler: Harry drives the Sword of Gryffindor up through the roof of the Basilisk's mouth and into its brain to kill it]].
* ReptilesAreAbhorrent
* SheIsTheKing: The Basilisk is the King of Serpents. Yet Slytherin's one is a female.
* UndyingLoyalty: To Slytherin and his heir.
--->'''Tom Riddle''': Parseltongue won't save you now, Potter; it only obeys '''''ME!'''''
* YourTomcatIsPregnant: Missing the scarlet plume on the forehead characteristic of male Basilisks.
** Although in the Main/LEGOAdaptationGame, it has the plume.

! The Gringott's Dragon
An ancient and decrepit Ukranian Ironbelly dragon that guards a chamber in Gringott's bank. The trio uses it to escape in the seventh book.
* BadassGrandpa
* ColdBloodedTorture: Went through some severe abuse before it was released. For reference, the goblins had conditioned it to associate the sound of metal with pain by ''repeatedly stabbing it with a burning sword''. In the movie, the poor thing ''whimpers'' when it hears that noise.
* DragonHoard: A rather dark deconstruction; this dragon is ''forced'' to guard a hoard.
* GiantFlyer
* HandicappedBadass: It's blind and has clearly seen better days, but it's still quite strong.
* OurDragonsAreDifferent
* WoobieDestroyerOfWorlds: It basically amounts to a scared, brutally tortured puppy in the body of a huge, fire-breathing beast. Once it's been freed, you better believe that it went on a ''rampage''.
