Although not always well behaved, the Hooligan Tribe's dragons have made themselves at home in Berk and live with them. Naturally this was not a smooth change, but they have integrated with their human allies.


Toothless is the name of Hiccup's Dragon in both the book series and the film franchise and is the Dragon protagonist. In the books, Toothless is a young Seadragonus Giganticus Maximus, although it is originally believed he is a Common or Garden Dragon, while he's a larger, black Night Fury in the film adaptation.

He is the quintessential dragon in the series, and remains unrivaled in intelligence. He is presumed to be the only living Night Fury, at least on Berk and the surrounding Isles. Better said in the whole world probably.

  • The Ace: In terms of speed, firepower, and intelligence, the Night Fury is rarely matched. The other Hooligan dragons are easily outclassed by Toothless's abilities, and only the Skrill (who is in same dragon class as Toothless; Strike) has been able to rival him in all aspects. To drive the point home, whenever something affects, scares off, or captures Berk's other dragons, Toothless is usually the only one who manages stay with the riders and protect them from further harm.
  • Adaptational Angst Upgrade: In the books, Toothless didn't have deal with a war with Vikings, losing a part of his tail, and being the Last of His Kind.
  • Adaptational Badass: In the books he's a Basic Brown/Garden Dragon, one of the smallest, most common dragon species (the template for the Terrible Terrors in the movies) while in the films he's a Night Fury, a Lightning Bruiser phantom dragon nicknamed "the unholy offspring of Lightning and Death." Though Book 11 reveals that the book series Toothless is an adolescent Seadragonus Giganticus Maximus, the same species that the Big Bad of the first film was based off of. It is further revealed that Toothless will grow up to be the size of a mountain, dwarfing even the Alpha dragons of the films.
  • Affectionate Nickname: Is affectionately referred to as "Bud" by Hiccup.
  • All Animals Are Dogs: Toothless's behavior is drawn from a hodgepodge of various animals. Creators have said that the aim was to create a character dog owners could look at and see their own dog, while at the same time cat owners could look and see their cats. Some of his behaviors are also based on horses, others on birds.
  • Amazon Chaser: In the third film, when he meets the Light Fury. After Toothless draws a picture of her, she accidentally steps on part of it, causing Toothless to growl at her (the same way he did to Hiccup in the first film). However, the Light Fury growls right back. And Toothless is even more smitten.
  • An Arm and a Leg: Lost part of his tailfin due to Hiccup's invention. This is one of the reasons he and Hiccup meet and befriend one another.
  • Artificial Limbs: Toothless has a very complicated artificial tail fin made for him by Hiccup. He initially needed Hiccup mounted to operate a mechanical system to help him fly but Hiccup eventually devises a more complex mechanism that allows the prosthetic fin to mirror his real one so he can fly on his own.
  • Asskicking Equals Authority: Becomes Alpha Dragon by challenging and defeating the reigning Alpha. Said reigning Alpha is a massive Bewilderbeast that is hundreds of times bigger than Toothless and has mind control powers. Toothless defeats him in a head on fight!! His first act as Alpha? Command the swarm of dragons to blast the Bewilderbeast into submission!
  • Babies Ever After: Has three babies with the Light Fury at the end of Hidden World.
  • Badass Adorable: He’s one of the very few dragons who’s traditionally cute rather than Ugly Cute... and he’s got a Breath Weapon that’s basically a Wave-Motion Gun built into his throat.
  • Badass in Distress: He gets mind-controlled by the Dark Alpha during the beginning of the attack on Berk and Drago seizes him as a mount. Luckily Hiccup manages to get through to him.
  • Berserk Button: He really hates the Whispering Death. Just its presence makes Toothless fly into such a rage to the point he even disobeys Hiccup.
  • Beware the Nice Ones: When he's not in battle, he's like a cuddly pet. When in battle, just pray he's on your side.
  • Big Brother Instinct: Don't hurt Hiccup if you know what's good for you—he made sure a Monstrous Nightmare got the message. In the second film, Hiccup's put through the ringer enough to enrage Toothless to the point that he takes on the Bewilderbeast from the ground. This thing is twice the size of the Red Death, and Toothless specifically takes it on without Hiccup, so he can't fly or outwit his enemy. No tricks, no traps, just pure fury and willpower enough to free the dragons from the Bewilderbeast's control. If it's not clear yet, do not mess with Hiccup, ever. Regardless if you are human, dragon or whoever; do not do it
  • Big Good:
    • Becomes the Alpha of the dragons by the end of the sequel, with Hiccup as the new Chief of Berk.
    • He's also this in the Hidden World, which is quite possibly the last dragon sanctuary on the planet.
  • Bioluminescence Is Cool: His back begins glowing blue in the climax of How to Train Your Dragon 2.
  • Breath Weapon: Night Furies have a unique one that launches small precise blue fireblasts that explode when they hit something, as opposed to a stream of fire, which proves far more destructive than the more traditional flames. They can adjust the size of the blasts, ranging from fairly harmless bursts that do little more than stun, up to huge explosions. He can also spit narrow jets of flame, which he uses to make a nest early in the first film.
  • Cat Like Dragons: One of the most iconic examples.
  • Cute Bruiser: A cuddly reptile that is also the most feared dragon.
  • Dark and Troubled Past: Implied. Much of Toothless' past remain a mystery except that he and the rest of the Berk dragons were under the thumb of the Red Death. In the third movie, Grimmel reveals he hunted and killed every Night Fury...except Toothless. This means that Toothless was somehow separated from his family at a young age and then somehow became a slave to the Red Death.
  • Dark Is Not Evil: Movie only, where he is a Night Fury, a dark coloured species with a semi-demonic look.
  • Deathbringer the Adorable: He's a Night Fury, one of the most feared dragons in history. In person, he's rather cat-like, occasionally with the same level of maturity.
  • Determinator: Nothing stops him from protecting Hiccup; not a cliff, not a chain and especially not other dragons.
  • Defrosting Ice King: To say he was hostile to Hiccup at first is an understatement. Of course, Hiccup did cut off part of his tail, preventing him from flying. It was through building another tailfin and helping him fly again that Hiccup managed to win his trust.
  • Deuteragonist: The second main focus after Hiccup.
  • Disabled in the Adaptation: In the original books, Toothless never acquired a prosthetic tail.
  • Disabled Love Interest: Inverted. Toothless is the deutergaonist of the franchise and has a prosthetic tail. And in the third film, he becomes mates with unnamed Light Fury.
  • The Dreaded: Implied to be this to (most) vikings by The Dragon Manual.
  • Extreme Mêlée Revenge: Cue Toothless taking on and beating the crap out of said Bewilderbeast, then usurping the Alpha role from it and using its newfound power to deliver a No-Holds-Barred Beatdown upon the giant dragon and its trainer.
  • Female Feline, Male Mutt: With the unnamed Light Fury. Behaviorwise, she's basically a cat, but Toothless has always been an amalgamation of various animals, with dog and cat featuring in more or less equal measures.
  • The Fettered: Shows signs of this, especially in various scenes in the T.V. series. Toothless largely follows Hiccup's "do not kill" philosophy toward his enemies, and thus often holds back when fighting them. If he stops holding back then the fight usually ends quickly but the enemy's life will be in danger.
  • Fluffy the Terrible: His name is Toothless, plus he's a Night Fury.
  • Game Face: Toothless extends his teeth when eating or being aggressive.
  • Genius Bruiser: Night Furies are the cleverest dragon species.
    • Toothless has repeatedly shown to understand meaning behind behaviors of other species, such as when he understood the meaning of Hiccup's smile (for most animals, baring one's teeth means agression), or when he intentionally copied Terrible Terror's challenge to a fight, causing Terror to open mouth in order to try and breathe fire (and leave itself vulnerable to his fire blast). He also seems to fully understand human speech, even though he cannot replicate it.
    • He understands that he needs Hiccup to fly immediately after first test flight with the new tail fin. Not to mention, he takes him about three seconds of wiggling his tail to figure out that Hiccup had attached a new tail fin in the first place, without turning around and looking at it.
  • Good Scars, Evil Scars: Upon closer inspection, Toothless has a number of scars on his body. It's heavily implied that his scars are a result of him being trapped by Hiccup's bola shooter.
  • Guile Hero: Toothless must've been taking lessons on this from Hiccup, as in the season one finale, he stops eating and thereby forces his captors to remove his muzzle to try to force feed him. He immediately hits them with a plasma burst and tears off his remaining restraints, then swats the guards with his tail.
  • Handicapped Badass: One of his tail fins is lopped off by Hiccup early on in the first movie. Throughout the show, Toothless tends to only be inconvenienced whenever Hiccup isn't around to help him fly.
  • Heel–Face Turn: In the first film he went from a sort of unlikable and stubborn dragon to a cute, sweet, and eternally loyal badass.
  • Hellish Pupils: Deliberately invoked: when he becomes angry his pupils narrow into vertical slits, but when he's calm and happy they're round.
  • Heterosexual Life-Partners: An interspecies example with Hiccup, a Viking human.
  • I Am Not Left-Handed: Toothless generally holds back his firepower in fights, unless he's fighting a mountain sized dragon.
  • Informed Ability:
    • In the movie, Night Furies are said to be the fastest and never miss their mark. In the series, Toothless has missed a few times and Stormfly is said to be getting closer to his speed. Toothless does have a handicap, though, and by and large every target in the film was stationary (relatively or otherwise).
    • Likewise, both the tie in ads and Defenders of Berk states that Night Furies only have six shots. Toothless regularly unleashes far more in a fight.note 
  • Interspecies Romance: With the unnamed Light Fury. DeBlois commented that the Light Fury is not actually a Night Fury, just a similar related species. This doesn't stop Toothless from courting her, and later, their mutual attraction.
  • It Can Think: As noted above in Genius Bruiser, Toothless is incredibly intelligent. When Hiccup draws him in the first movie, he recognizes himself. This is potentially based off of the mirror test used in animal studies to determine whether or not an animal can recognize its own reflection. Toothless recognizing that the drawing Hiccup makes is intended to be him shows that he's a step above most animals in intelligence, as very few animals are known to be able to tell that renderings of themselves are indeed themselves.
  • Jerk with a Heart of Gold: He may be smug, but he still cares for Hiccup and loves him. He even nearly gets killed when he saves Hiccup from The Red Death.
  • Last of His Kind: Implied to be the last remaining Night Fury. The Hidden World confirms this, with his entire species being hunted to extinction by a notorious dragon poacher named Grimmel.
  • Let's Get Dangerous!: When they encounter Eret's dragon-hunting crew, Toothless goes into screeching, plasma-shooting blur mode... which is significantly less effective in broad daylight.
  • Lightning Bruiser: A flying stealth plasma cannon. He is a Night Fury after all, and is no exception to the species.
  • Lightning Can Do Anything: With a little help from the Lightfury demonstrating her own cloaking ability, Toothless realizes his ability to channel electricity. Though whether it allows him "cloak" like the Lightfury or if it's an instance of Ride the Lightning is a bit unclear.
  • Love at First Sight: When he finally meets the Light Fury, Toothless is instantly smitten.
  • Masculine Lines, Feminine Curves: With the unnamed Light Fury, who is softer and rounder in appearance; whereas Toothless has sharper, more angular features.
  • Meaningful Name: Toothless has retractable teeth.
  • Monster Lord: By the end of HTTYD 2, Toothless is the new dragon Alpha.
  • Moody Mount: Sometimes he'll decide, on a whim, 'T-T-T-Toothless do b-b-barrel roll...' and Hiccup will just have to hold on.
  • My God, What Have I Done?: Has this reaction after realizing that he was hypnotized into killing Stoick. note 
  • Mysterious Past: Toothless's life before Hiccup is largely a complete mystery. We know he was helping the dragons that raided Berk for food, and the series reveals he had rivalry with a certain Whispering Death.
  • Non-Indicative Name: His teeth are retractable, not missing. Doubles as a Meaningful Name — if he's not given a reason to be otherwise, he's gentle as can be.
  • Pale Females, Dark Males: With the unnamed Light Fury. While she is a white Light Fury, Toothless is a black Night Fury.
  • Panthera Awesome: Has several characteristics of a panther and even moves around like a panther.
  • Papa Wolf: In the third film's ending, he becomes a father of three with the Light Fury as the mother. When a grown up Hiccup and Astrid with their two kids find them, Toothless menacingly approaches them. And had Toothless not recognized his friend, it's highly likely he would've killed him in defense of his family.
  • Phrase Catcher: Two lines precede his appearance in the first movie, whenever the vikings hear his signature whine. Played for laughs the last time it is said.
  • Pint-Sized Powerhouse: Toothless is one of the smallest dragons that can be ridden, and he doesn't measure up to many other dragons in terms of generating actual fire. But his unique form of fire breath lets him generate small, precise shots with extreme explosive force, more like an artillery strike than a blast of fire. This lets Toothless damage other dragons, which are immune to fire, with his shots, up to and including the Red Death and the Bewilderbeast, two dragons that dwarfed Toothless like an elephant dwarfs a rat. Despite his size, he is much stronger than he looks, tossing off a Monstrous Nightmare and also pinning Stoick.
  • Red Eyes, Take Warning: The sclera in Toothless' eyes will turn red around the edges when he gets exceptionally angry, likely from blood rushing to them. Given that he belongs to the most feared species of dragon in the world, this is understandably a very strong indicator that whomever or whatever he's looking at is in a load of trouble.
  • Red Is Heroic: His normal tailfin is with Berk's symbol also painted white on it.
  • Revenge Before Reason: Wouldn't even let Hiccup get on him to let him fly in "What Flies Beneath" because of his grudge with a Whispering Death, even though it meant he couldn't fly and was left at a serious disadvantage.
  • Ridiculously Cute Critter: Toothless is essentially a giant, winged axolotl, complete with "gills" reimagined as an expressive fleshy crest on his neck.
  • Shipper on Deck:
    • The look on his face after Astrid pecked Hiccup's check in the first movie.
    • And the way he nudged Valka into Stoick's arms, plus his expression, suggests that this is something of a part time hobby for him.
  • Shock and Awe: The final movie has him mastering the ability to summon and manipulate lightning.
  • Silent Snarker: In the movie. He is the most expressive dragon, primarily due to his size-changing pupils. He takes after a certain someone.
  • Snarky Nonhuman Sidekick: To Hiccup. In the series he certainly has his moments of snark.
  • Super Reflexes: Not only lightning fast in a straight line, but the most agile and maneuverable of the dragons, excepting only Meatlug (who is the nearest thing this 'verse has to a helicopter), at one point using his agility to keep up with a Speed Stinger on foot.
  • Super Speed: One of the fastest species of dragons.
  • Takes Ten to Hold: After forming a close bond with Hiccup, Toothless became highly protective of him, and reacts very strongly to any perceived threat to the young Viking. When Hiccup's nearly successful attempt to prove to his village that dragons and Vikings can coexist is botched by Stoic hitting the metal cage of the arena, the sound of which sending the Monstrous Nightmare into a fury, Toothless comes to Hiccup's rescue and fights off the other dragon, only to get jumped by the village, then pinned down and captured by nearly half a dozen Vikings. Of course, that was after he easily knocked three of them away and nearly killed Hiccup's father, Stoic.
  • Technicolor Fire: His explosive fireblasts are blue, and he can also breathe narrow jets of blue flame, which he uses to make a nest in the first movie.
  • Throat Light: His Super Mode involves his back glowing, as shown in the climax of How to Train Your Dragon 2.
  • Took a Level in Badass:
    • In the second movie, Toothless unlocks a blue glow and challenges Drago's Bewilderbeast after the latter attacks Hiccup. And wins. Thus, Toothless becoming the Alpha of the Berk dragons.
    • The third film has not only Toothless unlock the ability to summon lightning to his body that would help to camouflage but also him becoming the alpha of the Hidden World.
  • Trademark Favorite Food: Downplayed. Toothless has a liking towards all types of fish but his favorite kind are trout.
  • Troll: When camping with Hiccup, Toothless snatched a fish from a Terrible Terror, deliberately provoked it into trying to attack him, then shot a fireball down its throat, smiling smugly the whole time.
  • Tsundere: Toothless likes to switch among affectionate, aloof, and hostile at the drop of a hat. Yet he'll always pull through for Hiccup in the end.
  • Uncatty Resemblance: To Hiccup, being (comparatively) small, smart, snarky, deceptively strong, have green eyes, and use a prosthetic body part. According to Valka, they're even in roughly the same age range!
  • Undying Loyalty: To Hiccup. He would protect Hiccup from bigger dragons, Vikings, and himself when gets too carried away with his inventions. Not even Mind Control can make him hurt his rider.
  • Unstoppable Rage: We see a few glimpses of how terrifying he can be when his trainer/friend Hiccup is threatened. First one was when Hiccup was tackled to the ground by Astrid when she sees Toothless nearby. Toothless, taking it as Astrid attacking Hiccup, goes absolutely mental and charges at her, Hiccup snaps him out of it but even as he was introducing Astrid to him Toothless was giving her an absolutely terrifying Death Glare as well as a snarl to remind her that he still wasn't finished with her. Later when Hiccup's life is in danger in the fighting ring, Toothless hears his cries, proceeds to speed through the forest, jump through into the ring and deliver a Curb-Stomp Battle on the offending dragon. Also in the second movie when Drago orders the Bewilderbeast to end Hiccup, Toothless dives to take the blast, then blows the ice prison up, declaring to all that his Berserk Button is well and truly pressed. He then channels a Godzilla impersonation that is far more accurate than a twenty-foot-long animal has any right to pull off.
  • Violently Protective Girlfriend: Gender-inverted. Toothless becomes fiercely protective toward the Light Fury in the third film. To the point of surrending against Grimmel when the hunter threatens to harm her.


Snoutlout's Monstrous Nightmare. While he's a very powerful dragon, he has an unruly personality and tends to ignore his owner's commands.

  • Adaptation Name Change: Snotlout's Monstrous Nightmare in the books was called "Fireworm"
  • Adaptational Heroism: While he's still belligerent, he doesn't have Fireworm's Chronic Backstabbing Disorder.
  • Blow You Away: Astrid discovers he can create a powerful wind attack by clapping his wings together.
  • Cool Bike: His horns resemble motorcycle handlebars, which is especially noticeable when Snotlout is riding him.
  • Chronic Hero Syndrome: Out of all the dragons Hookfang shows this characteristic the most, in the show having at least two separate instances of answering another dragons distress call before any of the humans know whats going on and insisting on saving the distressed dragon even at his own risk. notably in both of these cases the dragon in question needed help defending their eggs
  • The Ditz: He has shown to be rather... spacey.
    • In one instance, Snotlout tries to prove their bond by leaping from Hookfang, who did not notice until Toothless informed him.
    • Another time he did not notice Snotlout screaming due to watching a falling leaf.
  • Gender Flip: Fireworm (Snotlout's Monstrous Nightmare from the books) was female. Hookfang is male.
  • Jerk with a Heart of Gold: Generally indifferent to his owner and tends to cause intentional harm to him for a quick laugh, but always proves to care about him when the chips are down.
  • Let's Get Dangerous!: He listens to Snotlout's orders much more closely when either of them is in danger.
  • Lightning Bruiser: The physically strongest of the dragons by far, has the most powerful breath attack after Toothless, and is beaten only by Toothless and Stormfly in speed.
  • Living Emotional Crutch: When Snotlout thought Hookfang was going to leave him for a female Monstrous Nightmare, he was so depressed he was ready and willing to quit being a dragon rider and leave for Berk.
  • Morality Pet: Snotlout's love for his dragon is one of his better qualities.
  • Running Gag: Has a tendency to set the pants of his rider on fire. Good thing Gobber had his "iron skivies"!
  • Simple, yet Awesome: In the second film, Hiccup uses Monstrous Nightmare saliva to coat a wire sword, which he can then ignite. This helps him tame dragons, as creating the fire makes dragons see him as one of them.
  • Snarky Nonhuman Sidekick: His silent reactions to Snotlout's antics are probably second only to Toothless, especially in the series.
  • Strong, but Unskilled: He's a very powerful dragon, but his poor teamwork with his rider makes him much less useful than he could be.
  • Took a Level in Kindness: At the start of the movie, he was just as angry and Viking-hating a?s most dragons. In the season 1 finale he acts to defend a bound Hiccup and Toothless without any order or request from Snotlout. By season 3 of Race to the Edge, he seems to have finally warmed up to Snotlout to the point of obeying him much more frequently.
  • Trademark Favorite Food: His favorite type of fish is mackerel.
  • Uncatty Resemblance: Both Snotlout and Hookfang look big and tough, and act mean and irresponsible, but are actually examples of a Jerk with a Heart of Gold.
  • Vitriolic Best Buds: Sure, he sets Snotlout's pants on fire regularly, but when Snotlout is in genuine danger, Hookfang always comes through. Snotlout himself was clearly distressed when it looked like Hookfang would have to be put down in "Viking For Hire".
  • With Friends Like These...: While he always pulls through for his rider in the end, that still doesn't stop him from being a massive jerk most of the time.


A Deadly Nadder, Stormfly is Astrid's dragon and the two often act as Hiccup and Toothless' main backup.

  • All Animals Are Dogs: Zig-zagged, her design and behavior are both very bird-like but she occasionally displays dog-like qualities, such as a love of playing fetch.
  • All-Loving Hero: In the show and second movie, Stormfly befriends people who start out as villains but then become good. In fact, her saving Eret is what prompts his Heel–Face Turn.
  • Attack Its Weak Point: Astrid tries to stop Stoick from grabbing Stormfly on the nose, as a Nadder's weak point is a blind spot directly in front of it. Stormfly thinks this trope is happening and panics. That said, Stormfly allows Astrid to touch her there when she hugs her dragon in "Heather Report" part 2.
  • Bioluminescence Is Cool: When she flies Astrid and Hiccup into the Hidden World, the underground realm's strange illumination reveals that she has a spectacular pattern of pale-glowing rings on her wings and body.
  • Improbable Aiming Skills: She usually attacks by flinging a barrage of spines at her target but in "Tale of Two Dragons" Snotlout discovers she can fire a single spine with pinpoint accuracy.
  • Nice Girl: She's right up there with Meatlug as a contender for being one of the nicest dragons.
  • Power-Up Food: Astrid uses chicken to make her fly faster.
  • Spike Shooter: All Deadly Nadders can shoot spikes from their tail, but Stormfly does it a lot in the TV series.
  • Took a Level in Kindness: At the start of the movie, she was just as angry and Viking-hating as most dragons. In the season 1 finale she acts to defend a bound Hiccup and Toothless without any order or request from Astrid.
  • Trademark Favorite Food: Apparently, Stormfly will let anyone ride her, provided they feed her chicken first. It Tastes Like Friendship.
  • Uncatty Resemblance: Graceful and beautiful, but often aggressive and violent - a lot like Astrid.


Fishleg's large but cuddly Gronkle.

  • Acrofatic: Rather subtle in that Meatlug can keep up with the group despite her appearance and the fact the rider is Fishlegs; she is also pretty agile in combat too. Her short wings and it's hover ability also make her far more resistant against strong winds than normal dragons with large wings.
  • Adaptational Badass: Horrorcow (Fishlegs's dragon from the books) was a Basic Brown (the second smallest and most common dragon species after the Common-or-Garden Dragon) who was a vegetarian. Meatlug is a much larger Gronkle and an Extreme Omnivore.
  • Adaptation Name Change: From "Horrorcow" to "Meatlug," as she's not as cow-like as her book counterpart.
  • Bruiser with a Soft Center: Fishlegs mentions several times that she is as much a sweetheart as she is a hitter.
  • Extreme Omnivore: Gronckles can eat rocks and regurgitate them as flaming boulders. Meatlug and Fishlegs have trained so she can do this in combat by catching catapulted enemy boulders in her mouth and sending them back.
  • Fartillery: Can stun a whispering death that was coming at her backside.
  • Gentle Giant: She's about as sensitive and sweet-natured as a flying tank can get.
  • Mundane Utility: In "The Iron Gronkle", Fishlegs discovers that by ingesting specific metals Meatlug can regurgitate a new alloy, Gronkle Iron, which is lighter than period iron but significantly stronger as well. In "Night of the Hunters II", he discovers Riker's dragon hunters have perfected Gronkle Iron and steals the formula from them.
  • Nice Girl: One of the sweetest and most compassionate dragons in the entire franchise.
  • Platonic Life-Partners: Has the closest relationship with her rider, after Toothless.
  • Samus Is a Girl: Fishlegs thought she was male at first until her true gender was revealed in the Christmas special.
  • Spin Attack: The "Gale Force Gronkle." The downside is it leaves Fishlegs horribly dizzy.
  • Stone Wall: The slowest of the dragons and the least equipped for combat, but is naturally sturdy.
  • Took a Level in Kindness: At the start of the movie, she was just as angry and Viking-hating as most dragons. In the season 1 finale she acts to defend a bound Hiccup and Toothless without any order or request from Fishlegs.
  • Uncatty Resemblance: She's chubby, slow and gentle, not unlike Fishlegs.
  • Undying Loyalty: She flew into a storm and against a Scauldron to protect Fishlegs.
  • Your Tomcat Is Pregnant: To Fishlegs' subdued surprise in the Christmas special.

    Barf and Belch

The twins' Zippleback. Is just as eager to cause destruction and chaos as the people who ride them.

  • Organ Autonomy: Ruffnut and Tuffnut know if they're on the wrong head (one has teeth, the other doesn't.) They also hug each head separately when bidding goodbye at one point.
  • Simple, yet Awesome: In the second film, Hiccup collects Zippleback gas and stores it in canisters, which he uses to simulate dragon fire that will help dragons trust him more easily since they see him as a dragon. On the more combat-oriented side of things, Barf is shown strafing the battlefield with huge gas clouds for the other Berk dragons to ignite, so they can generate huge explosions and waves of fire without putting Ruff and Tuff in danger.
  • Stuff Blowing Up: The heads together have the highest firepower of the main five. They abuse this constantly in the second film.
  • Took a Level in Kindness: At the start of the movie, they were just as angry and Viking-hating as most dragons. In the season 1 finale they act to defend a bound Hiccup and Toothless without any order or request from the twins.
  • Uncatty Resemblance: The two heads often bicker with each other but can work as a team, just like the ditzy Half-Identical Twins who ride them.
  • Undying Loyalty: Barf and Belch will try their best to follow all of the twins commands, even if the commands contradict each other and force the dragon into a stall.
  • Wonder Twin Powers: Separately, the heads aren't as dangerous since the gas is merely an annoyance and the spark isn't powerful. Together, they can create huge detonations.


A Thunderdrum that formerly swam the waters around Berk before Stoick forged a friendship with it, and it subsequently became Stoick's dragon.

  • The Bus Came Back: Returns in the spin-off game School of Dragons, along with Bing, Bam and Boom and the series finale during the fight against the dragon hunters.
  • Demoted to Extra: Other than his introduction episode he's had only minor parts. More notable in that he is the Chief's dragon and yet we only see Toothless eating near the family table. Even if he doesn't fit inside the house (his mouth is wider than Stoick's body) you would still expect him to pop up more. Then he gets Put on a Bus to protect some adolescent Thunderdrums on Dragon Island.
  • Doomed by Canon: Once Stoick's dragon in How to Train Your Dragon 2 was revealed, Thornado had to be Put on a Bus to make way for Skullcrusher.
  • Fire-Forged Friends: Bonded with Stoick by fighting off a horde of wild boars.
  • Meaningful Name: Blending 'Thor' because of Thunderdrom's legendary connection to the lightning god and 'tornado' because of its strength.
  • Papa Wolf: To a group of adolescent Thunderdrums in "Bing! Bang! Boom!", so much so that Stoick ultimately sets Thornado free to protect them on Dragon Island.
  • Small Name, Big Ego: Stoick recited the legend about Thunderdroms in front of it and now "it won't answer to anything else" than Thornado.
  • Smarter Than You Look: His design is even more ridiculous and exaggerated than most of the other dragons, and when you see him going straight at Toothless with his mouth wide open, you expect him to suffer the same fate as one Terrible Terror in the movie. Except that he dodges Toothless' blast and immediately goes back into the water, where he can hide and pull surprise attacks on the Vikings. He doesn't even have the ability to fall for that fate given his unique breath weapon.
  • Uncatty Resemblance: He is just as stocky and stubborn as his rider.


A young Monstrous Nightmare tamed by Gustav. While well-meaning, Fanghook is usually just as accidentally destructive as his rider.

  • Annoying Younger Sibling: Toothless treats him like this, generally finding him quite irritating.
  • Expy: In universe - Gustav wasn't the most original when it came to naming his dragon. He picked a Monstrous Nightmare that looks just like Hookfang and named it "Fanghook".
  • Heterosexual Life-Partners: Unlike Hookfang and Snotlout, he and Gustav are as thick as thieves and usually on the same mental wavelength.
  • Running Gag: He tries to put burning things out like a human, by blowing on them. Being a dragon, this just makes them burn even more.
  • Uncatty Resemblance: Somewhat ditzy, overenthusiastic and unintentionally destructive, just like his rider.
  • Up to Eleven: This for Hookfang's ditzy tendencies, much like Gustav himself in relation to Snotlout

    Academy Terrible Terrors

A group of Terrible Terrors trained by the riders on a bet made by Fishlegs and Snotlout.

Hiccup's Terror, Sharpshot, a loyal little dragon trained to shoot with impressive accuracy.
Astrid's Terror, Sneaky, a Stealth Expert.
Fishlegs's Terror, Iggy, which he trained to fetch objects by cue cards.
Snotlout's Terror, Pain, which he "trained" to bite things (mostly himself) and be nearly impossible to remove once it does.
Ruffnut and Tuffnut's twin Terrors, Butt and Head, which they trained to run into each other.
  • All There in the Manual: The names of Astrid and Snotlout's Terrors weren't mentioned in the show, but the mobile game reveals them to be called Sneaky and Pain, respectively.
  • Chekhov's Gun: All their unique skills came in handy for rescuing Meatlug from the Outcasts.
  • Early-Bird Cameo: Each of the Terrors uses a model that was seen around Berk before. For example, Snotlout's was the one that was knocked out by Gobber's stench.
  • Instant Messenger Pigeon: Fishlegs and Hiccup train their Terrors to carry messages.
  • Mythology Gag: Hiccup's Terror, Sharpshot, matches up closely with Book!Toothless as Toothless' species in the books were the source for Terrible Terrors.


A Rumblehorn who has become Stoick's dragon in the second film since Stoick let Thornado go in the series. After Stoick's death, Eret adopts Skullcrusher as his own dragon.

  • Names to Run Away from Really Fast: Stoick certainly picked an intimidating name for this dragon.
  • Not Evil, Just Misunderstood: When Skullcrusher first appeared chronologically, he was knocking down Hiccup's base, but only because he wanted them to leave the island due to a tidal wave coming there soon.
  • Scarily Competent Tracker: Rumblehorns are from the newly-discovered Tracker class. In the second film, Skullcrusher is able to find Hiccup at the glacial sanctuary just by sniffing his helmet, even though the helmet had been left in the water for a while.
  • Super Strength: He could tear through a wood base like nothing, and strike a boulder wall hard enough to shake it and knock off any looser materials on top.
  • Uncatty Resemblance: Huge, strong, and intimidating, but also benevolent and protective, just like Stoick.


Gobber's dragon in the second film, a Hotburple who Gobber uses to keep the fires in the forge aflame...when he isn't asleep, anyway.

  • Beware the Silly Ones: Grump may be lazy and goofy looking, but he can be quite terrifying once ticked off, as some dragon hunters learned the hard way.
  • Brilliant, but Lazy: His first chronological appearance has him in the dragon hunter's captivity. Thing is, Grump can chew through otherwise dragon proof metals, and is capable of throwing his weight around when he feels like it. But he's so lazy, that the hunters don't even bother keeping him in a cage, and he's allowed to wander around their base since they think he's no threat.
  • Extreme Omnivore: Like Gronckles, but since he's a Hotburple he eats iron instead of rocks.
  • Lazy Bum: Grump is rather lazy and spends most of his time asleep. According to the official site, he'll even fall asleep while in mid-flight.
  • Like an Old Married Couple: The official site describes his relationship with Gobber as this, since Gobber often has to put up with his laziness.
  • Mundane Utility: Gobber uses him to light the fires in his forge.
  • No-Sell: Is able to bite through dragon-proof metal.
  • Sleepyhead: Grump spends most of his time napping. Even when reunited with Gobber, he falls on his master and immediately falls asleep.
  • Tastes Like Friendship: Gobber wins Grump's affection by feeding him some scrap metal and rocks.

    Smidvarg and the Gang 

A pack of Night Terrors, led by an albino named Smidvarg, that serve as the sentries of the Edge.

  • Animal Espionage: Serve as the Edge's sentries. Unfortunately, the Dragon Hunters start exploiting this by knocking them out with dragon root arrows, forcing the Riders to erect a watchtower and start supplementing them with human lookout rotations.
  • Dark Is Not Evil: Though they start out as a Monster of the Week, they turn out to be friendly and playful once tamed.
  • Monster of the Week: Start out as this in their first appearance.
  • Synchronized Swarming: As is characteristic for all Night Terrors. The Dragon Riders take it upon themselves to teach them how to swarm in specific patterns for tactical purposes.


Spitelout's Deadly Nadder.

  • Flat Character: As opposed to Fanghook, Kingstail doesn't exhibit a unique personality or take after its rider in any meaningful way, and might as well be a prop.

    Whip and Lash 

Bucket and Mulch's Hideous Zippleback.

  • Flat Character: See Kingstail's entry. Less egregious of a case, however, as Whip and Lash, along with their riders, rarely make more than token appearances and are usually overshadowed by the other members of the auxiliary riders.

How well does it match the trope?
