    Regular Animals 

Hedwig (Gizmo)

Harry's faithful pet snowy owl, and aside from Hagrid, his first friend in the magical world.
  • Artistic License – Biology: 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 snowy owls bark instead of hoot.
  • Berserk Button: 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.
  • Cool Pet: A white owl that's also a personal mail carrier.
  • Crosscast Role: Her role was played by several male owls in the movies, due to the Artistic License – Biology shown above.
  • Empathy Pet
  • Heroic Sacrifice: 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 the Death Eater who killed Hedwig identifies Harry as the real one because his pet protected him. Hence why Voldemort immediately attacks him afterwards.
  • Killed Off for Real: Along with Mad-Eye Moody during the Battle of the Seven Potters.
  • Meaningful Name: St. Hedwig of Silesia is the patron saint of orphans.
  • Named After Somebody Famous: Harry named her after someone he read about in A History of Magic.
  • Pride: Hedwig's notably vain, and bites Harry when he keeps her cooped up in her birdcage for too long.
  • Red Oni, Blue Oni: Blue to Pigwidgeon's red.
  • Sacrificial Lion: Her death marks the end of Harry's childhood, according to Word of God.
  • Tsundere: Type A.
  • Undying Loyalty: Toward Harry. In the film version of Deathly Hallows, she takes this trope to its zenith when she tries to save him from the Death the cost of her own life.

Mrs. Norris

Argus Filch's Right-Hand Cat. 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.
  • Amplified Animal Aptitude: 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 understands "cat" and they have Bilingual Dialogue. The usual Fanon is that they have some kind of psychic connection.
  • Cats Are Mean: Played straight here; she actively warns Filch whenever students are doing anything he can punish them for.
  • Formally Named Pet
  • Kick the Dog: The first book indicates that it's the deep desire of many students at Hogwarts to give Mrs. Norris a good kick.
  • Morality Pet: To Filch, who sincerely loves her, far more than any of his students
  • Non-Human Sidekick
  • Right-Hand Cat
  • Shout-Out: Named, by Rowling's own admission, for the character of the same name in Jane Austen's Mansfield Park.


Hagrid's gigantic boarhound dog.
  • Adaptation Species Change: Fang is a boarhound/Great Dane in the books, but he's portrayed by a Neapolitan Mastiff in the movies.
  • Big, Friendly Dog: He warms up pretty quickly to Harry and his friends.
  • Deathbringer the Adorable: Fang is a huge dog that can be quite terrifying, so long as you know it's cuddly and loyal.
  • Kick the Dog: Quite literally - Fang gets hit by a Stunning Spell during Umbridge's attempt to fire Hagrid
  • Lovable Coward: Fang's as nice as can be, but when faced with a cloaked figure drinking from a unicorn's corpse, it will not stay by your side.
  • Loyal Animal Companion: To Hagrid, Harry and Ron.
  • What Happened to the Mouse?: 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.

Crookshanks (Crackerjack)

Hermione's pet cat.
  • Amplified Animal Aptitude: 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, knows how to freeze the Whomping Willow, and knows right away that dog!Sirius is not a dog.
  • Cats Are Mean: Subverted. While he's a bit of a JerkAss when he first appears, it's because he knows Scabbers is Wormtail in disguise.
  • Cats Are Snarkers: This Pottermore article shows his probable thoughts during Prisoner of Azkaban. They're very sarcastic.
  • Demoted to Extra: He does appear in the film adaptation of Prisoner of Azkaban, but his "constantly trying to eat Scabbers" subplot is cut out.
  • Evil Detecting Cat: The first thing we see him do in the books is pounce on Scabbers, who's actually Peter Pettigrew in disguise. Justified, because this is a species trait for Kneazles as a whole. (Ron comes to recognize his authority and has him check Pigwidgeon before deciding to keep him).
  • Half-Cat Hybrid: Half-Kneazle, half-cat.
  • Only Sane Man: The Pottermore article on his thoughts has him consider himself this, because he's the only one who realizes that Scabbers is an animagus.
  • Spanner in the Works: In the film adaptation of Order of the Phoenix, he eats 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.
  • What Does She See in Him?: In the aformentioned Pottermore article, he knows that Hermione likes Ron and wonders why.
  • What Happened to the Mouse?: 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.


Voldemort's pet snake from book four onwards, ready to kill and eat any who threaten her master.
  • Anti-Magic: Her venom is resistant to healing magic.
  • Artistic Licence: 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.
  • Chekhov's Gunman:
  • Face Stealer: She takes Bathilda Bagshot's place upon her death.
  • Familiar: Voldemort's connection with Nagini goes far beyond the normal connection Parseltongue allows.
  • Off with Her Head!: At the hands of Neville in the Battle of Hogwarts.
  • Reptiles Are Abhorrent: Nagini is just a normal snake, but it acts like a straight-up horror villain in book 7.
  • Right-Hand Attack Dog: Voldemort will frequently injure people and leave Nagini to finish them off and consume the remains.
  • Sssssnake Talk: Speaks parseltongue with her master on occasion.
  • Soul Jar: She's a living Horcrux, and is the final of Voldemort's Horcruxes to be destroyed before his demise.


The very old pet owl of the Weasley family.

    Magical Beasts 

Norbert the Norwegian Ridgeback Dragon

A dragon that Hagrid illegally wins as a prize 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. It was revealed in The Deathly Hallows that Norbert is a female.
  • Adaptational Attractiveness: 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.
  • More Deadly Than the Male: How Charlie figured out that she's a girl.
  • Our Dragons Are Different: 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.).
  • Reptiles Are Abhorrent: While not evil, dragons in general are portrayed as extremely vicious and impossible to domesticate. Of course, Hagrid being Hagrid, he adores Norbert and doesn't see him as a fire-breathing wild animal.
  • Samus Is a Girl: As Charlie reveals in the seventh book.
  • Tertiary Sexual Characteristics: Female dragons are larger and more aggressive than male dragons.


Dumbledore's pet Phoenix. His feathers were used as the cores for both Harry and Voldemort's wands.
  • Big Damn Heroes: Comes to Harry's aid in the Chamber of Secrets.
  • Cool Pet
  • Familiar
  • Heroic Sacrifice: He takes a Killing Curse for Dumbledore in Order of the Phoenix. Since he's a Phoenix, he gets better.
  • Long Bus Trip: It's explicitly spelled out after Dumbledore's death that Fawkes has left Hogwarts forever.
  • Meaningful Name: 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.'
  • The Phoenix
  • She's a Man in Japan: In the Italian translation of the books, the male phoenix Fawkes becomes female, and is named Fanny. Possibly due to the fact that in Italian, "phoenix" is a feminine word.
  • Swiss Army Tears: An inherent Phoenix ability.
  • Undying Loyalty: To Dumbledore and by extension Hogwarts. When Dumbledore dies, he no longer has a reason to stay.

Aragog (voice by Julian Glover)

One of Hagrid's pets, an 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).
  • Affably Evil: Not unfriendly, but pretty darn frightening.
  • Androcles' Lion: 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. 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.
  • Back for the Dead: In Half-Blood Prince.
  • The Bus Came Back: Not Aragog himself, but his children return during the Battle of Hogwarts, attacking Death Eaters and Hogwarts allies alike.
  • Cool Pet
  • The Dreaded: Acromantulas are feared all across the Wizarding World, and Aragog and his family are no exception.
  • Giant Spider
  • I Owe You My Life: 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. Unfortunately for Harry and Ron, Aragog's family extends that courtesy ONLY to Hagrid himself.
    • Also, Hagrid himself realized that upon Aragog's death, his children would no longer feel bound by the promise and it wouldn't be safe for him to go into their territory anymore. Even when Aragog was still alive but clearly sick and dying, Hagrid commented that it was getting risky for him to go and visit Aragog because his children were getting more aggressive towards him.
  • Interspecies Friendship: 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.
  • Keeper of Forbidden Knowledge
  • Non-Malicious Monster: 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.
  • Red Herring
  • Roaring Rampage of Revenge: 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.
  • The Scapegoat: For what the Basilisk did. To add further insult to it, Acromantulas hate and fear Basilisks.
  • Spiders Are Scary
  • Talking Animal: Being an Acromantula, he and his brood are able to speak.
  • To Serve Man: A species trait, though he himself refrains from eating humans in honor of Hagrid. His children, on the other hand, consider any human other than Hagrid fair game.

Slytherin's Monster

Appears in: Chamber of Secrets
The legendary Monster of Salazar Slytherin, intended to be awoken by Slytherin's heir to purge all the Muggle-borns in Hogwarts. Serves as The Dragon to the heir of Slytherin in Chamber of Secrets, where it ultimately dies.
  • Ax-Crazy: All of its lines are about murder, blood, or killing.
  • Chekhov's Boomerang: 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.
  • Deadly Gaze: Making eye contact with her is instantly fatal.
  • Death Glare: Literally. Eye contact with it means instant death.
  • Dragon-in-Chief: The Heir in the second book. While he was calling the shots, she was the one doing the dirty work.
  • The Dreaded: With the exception of roosters and the Heir, everyone is terrified of this thing. Even Acromantulas refuse to speak of her.
  • Eye Scream: Ends up on the receiving end of this, courtesy of Fawkes, which allows Harry to properly fight it.
  • Impaled with Extreme Prejudice: Harry drives the Sword of Gryffindor up through the roof of the Basilisk's mouth and into its brain to kill it.
  • The Paralyzer: Eye contact through a mirror or other reflections paralyzes the victim, which can be reversed.
  • Reptiles Are Abhorrent: Harry's ability to use Parseltongue foreshadows its role as a Basilisk, a humongous snake monster.
  • She Is the King: The Monster is called the king of its species, but this specific one is female.
  • Undying Loyalty: To Slytherin and his heir.
    Tom Riddle: Parseltongue won't save you now, Potter; it only obeys ME!
  • Your Tomcat Is Pregnant: Missing the scarlet plume on the forehead characteristic of it in myths.

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.
  • Berserk Button: He doesn't take kindly to 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.
  • The Cavalry: Leads the Thestrals of the Forbidden Forest against Voldemort's giants during the final stage of the Battle of Hogwarts.
  • Cool Horse
  • Giant Flyer: Has a large and formidable wingspan.
  • Mix-and-Match Critters: Half bird, half horse.
  • Off with His Head!: The Ministry is forced to perform this on Buckbeak after he "injures" Malfoy. Subverted thanks to Harry and Hermione's meddling with the Time-Turner.
  • Our Gryphons Are Different: Specifically, he's a hippogriff.
  • Pride: Enough to demand consent to be ridden (that whole bowing thing). It's a hippogriff trait.

The Hungarian Horntail

Appears in: Goblet of Fire

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.
  • Death by Adaptation: Falls to her doom during the movie.
  • The Dreaded: 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.
  • Mama Bear: 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.
  • Non-Malicious Monster: 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.
  • Our Dragons Are Different: Is based on a wyvern.
  • Reptiles Are Abhorrent: Subverted. They are extremely vicious by nature, but are not evil. And the one in the books/movies is just following her maternal instincts.
  • Shout-Out: The design of the Hungarian Horntail in the film was based off of the dragons from the film Reign of Fire. As is it's method of breathing firenote 


Ginny's pet Pygmy Puff, purchased on a trip to Weasleys' Wizarding Wheezes in 1996.

The Gringott's Dragon

Appears in: Deathly Hallows
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.
  • Badass Grandpa
  • Cold-Blooded Torture: 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.
  • Dragon Hoard: A rather dark deconstruction; this dragon is forced to guard a hoard.
  • Giant Flyer
  • Handicapped Badass: It's blind and has clearly seen better days, but it's still quite strong.
  • Our Dragons Are Different
  • Woobie, Destroyer of Worlds: 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.
