General
There are a variety of dragon species throughout the islands, ranging from small and mostly harmless to large and lethal, everywhere in between, and mixing all of that.
For individual dragons, see the entries where they come from.
- All Animals Are Domesticated: Averted. While Berk's dragons eventually settle in (though not always the most well-behaved), other dragons are still dangerous and often hostile, at least under certain circumstances.
- All There in the Manual: The Book of Dragons and Bork's Papers are in-universe manuals. In one of the shorts, "The Book of Dragons", we learn about several more dragons. Some have appeared in the show proper, others, like the Snaptrapper and Timberjack, haven't. At least a few species from the tv show and the second movie get expanded information on them in the ‘Rise of Berk’ App game.
- Animal Motifs: More than a few dragons have designs, behaviors, or abilities inspired by real animals. A lot of them have a mixture of traits from certain animals.
- Asskicking Leads to Leadership: They seemed to follow this rule in general. One is not born into the Alpha status but has to earn it through power. Once a dragon becomes the Alpha, it can control other dragons through sheer force of will.
- Breath Weapon: Almost all dragon species have them, and most commonly they breathe fire, which is created by expelling a flammable gas and then igniting it with sparks from a mechanism in the mouth/throat. The Stoker Class, in particular, are well-known for their firepower and high shot limit for their fire attacks. Certain species have more unique weapons, though.
- Hideous Zipplebacks exaggerate the gas to spark by having different parts in different heads. This means they technically breathe explosions, as their standard tactic is to exhale a cloud of gas and let it settle before igniting it in a single sharp burst. They can envelop prey in their gas and use it as a poisonous Knockout Gas instead of just blowing it up.
- Gronckles and Hotburples eat rocks and metals, heat them to melting point in their stomachs, and then vomit them up as globs of lava.
- Eruptodons consume lava and regurgitate it.
- Scauldrons spray superheated water to flash-boil prey.
- Changewings spit corrosive slime.
- Thunderdrums use sonic blasts that can pulverize stone.
- Night Furies shoot blasts of concentrated plasma, which explode when it hits a target.
- Flightmares spit a paralytic toxin that takes effect in seconds and can be absorbed through the skin.
- Skrills can launch bolts of lightning that can even hit multiple targets. They do this by absorbing ambient electricity from the clouds and exhaling specialized ionizing gas to give the projected lightning a route to follow.
- Bewilderbeasts swallow tons of seawater before regurgitating it as ice, and use that ability to make glacier nests.
- The Red Death exhales what looks like pyroclastic clouds— that is cloud-like formations of super-heated cinders and gas.
- Snow Wraiths and Windgnashers spit rapid-fire frost.
- Death Songs spew amber, which hardens when it cools, to cocoon and immobilize prey.
- In addition to their Vacuum Mouth, Submarippers weaponize the indigestible materials they swallow, coughing up the debris of rock formations and shipwrecks in the direction of their enemies.
- Slitherwings spit and excrete deadly venom that is debilitating in moments and lethal within a day.
- Sandbusters fire globs of superheated sand that hardens into glass.
- Grim Gnashers fire volleys of their own TEETH.
- Snifflehunches SNEEZE fire.
- Hobblegrunts breathe ethane and set it alight.
- Windstrikers fire super-heated air.
- Typhoomerangs and Stormcutters breathe their fire in flaming cones.
- Smothering Smokebreaths produce obscuring clouds of smoke to hide their movements.
- Sentinels utilize a weaker version of the Thunderdrum's sonic blast, coupled with extremely powerful gusts of wind from the beating of their wings.
- Shellfires launch molten boulders that explode like cannonballs and can hit a target from over a mile away.
- Gembreakers spit "loogies" of a burning blue liquid that explodes on contact with a solid object.
- Early-Bird Cameo: A lot of times, dragons that are shown or mentioned in the book pop up later in shorts of the television series itself.
- Elemental Powers: Most of the dragon species use at least one the elements of nature to their advantage. Whether it's emitting through their bodies, living in an element, or having an element as a Breath Weapon.
- Earth: Boulder Class Dragons are this due to either living in the ground or shooting magma (a liquid version of Earth) from their mouths. Sandbusters and Cavern Crashers are this as well due to also living the ground. Shellfires can shoot blue lava boulders.
- Fire: While most dragons can use fire for their Breath Weapon's, Stoker Class Dragons do it perfectly. If not, even better. They can even emit fire from their body parts too. Light Furies use fire to cloak themselves in a way through their plasma blasts. Mist Twisters can shoot fire from one of their heads.
- Wind: Sentinels use a big gust of wind to defeat other dragons. Windstrikers superheat air from their bodies before blasting it on their enemies. Submarippers suck in big amounts of air that not only sucks in anything water, but also sucks in prey from the air as well. Razorwhips can create tornadoes with their wings and tails.
- Water: Tidal Class dragons either live in the water or use water for their attacks.
- Lightning: Night Furies and Night Lights either use electricity for their attacks or to cloak themselves. But Seashockers and Skrills use this perfectly when it comes to battling other dragons.
- Ice: Bewilderbeasts, Snow Wraiths, and Windgnashers breath out blasts of ice. Mist Twisters can blast ice from one of their heads.
- Light: Flightmares, Fireworms, and technically, any dragon who eats the Glowing Algae, has the power of Bioluminescence.
- Shadow: Night Furies and Night Terrors can blend into dark environments.
- Plants: Foreverwings not only blend into the forests, but also, grow plants on their backs as well. Buffalords eat specific herbs that give their saliva healing powers.
- Crystal: Gembreakers have crystals for horns.
- Metal: Razorwhips have metallic scales.
- Poison: Venomous dragons inject poison on either Vikings or other dragons.
- Sound: Screaming Deaths and Thunderdrums roar very loudly to fight their opponents. Death Songs sing to attract prey.
- Elite Mook: Most dragon species have a known variant called a Titan Wing, which are larger, more colorful, and more aggressive members of whatever species it is.
- Flying Seafood Special: Most of the dragons, even the most flying specialized, are still very capable swimmers, and vice-versa. Many even use their wings as paddles, not unlike several seabirds.
Must come in handy when fish is a major part of many species' diet. - Giant Flyer: A majority of dragons are at least bigger than an elephant and are capable of flight.
- Gigantic Adults, Tiny Babies: Most dragons get really big, but their young ones more often than not hatch from ball-sized eggs and can be easily carried by a human.
- Handy Feet: Many species of dragons are capable of picking things up with their feet.
- Hellish Pupils: Most dragons have slit pupils. The thickness of the pupil however varies between species.
- It Can Think: Intelligence varies between species and individual dragons, but the protagonists learn that dragons are capable of problem-solving and will recognize previously used traps. Most show some signs of intelligent reactions, while others are smart enough to hold crude conversations with and operate simple machinery. Special mention to the Strike Class, as they're regarded to be the more intelligent species of their kind.
- More Predators Than Prey: A vast majority of dragons seem to be predatory (or at least omnivorous) animals. It makes one wonder how so many of them can find enough food to eat. It probably helps that some eat unconventional food like rocks or gems.
- More Teeth than the Osmond Family: Generally, the bigger the head the more teeth it has. A majority of dragon species have long sharp teeth that stick out their mouths. The current kings, however, are the Whispering Death (which has six rows of teeth that can rotate like a rock-cutter) and the Snaptrapper (which has four heads, each of which has three toothy jaws).
- Our Dragons Are Different: As seen in the rest of this page, dragons have many different species, and come in all shapes and sizes.
- Our Wyverns Are Different: There are a number of dragons with bodies structured like a wyvern.
- Predators Are Mean: There's a certain invocation of this. Canonically, all of the "friendly" species of dragons are piscivores (fish-eaters) and have no interest in animal flesh (except Stormfly, who will eat fish if offered but treats chicken as her Trademark Favorite Food). Those few that explicitly or implicitly do eat non-fish meat, however, have been villains — first the Whispering Death (although that is later shown not to be so bad), and then the Flightmare, who explicitly eats humans to boot, and then the Skrill, who chooses to go after sheep rather than fish upon being set free. By contrast, the Buffalord, which is a herbivore, is incredibly docile, to the point of barely caring that there are humans around it until they try to take it away from the island it lives in.
- Reused Character Design: A creatively utilized version of this trope is used according to the behind-the-scenes crew of How to Train Your Dragon 2. Various new dragons created for the sequel only used two basic dragon models. A modular system was used to add and switch around claws, spines, and horns onto different models, which in turn made 14 distinct models for new dragon species. the long-necked basic dragon model was used for the Hobblegrunt, Windstriker, Thornridge, Threadtail, Raincutter and two currently unnamed species. The burly basic dragon model was used for the Snafflefang, Shovelhelm, Snifflehunch, Windgnasher, Thunderclaw, and two other currently unnamed species.
- Unreliable Narrator: Several facts about the book are shown to be wrong, including that the Scauldron DOES have venom ("Dragon Flower"), and in regards to some dragon types it knows nothing (case in point: Night Furies).
- Weaksauce Weakness: Most species are susceptible to certain toxic substances like the toxic pollen of Blue Oleander, have a fear of Eels, can easily be infected by Grimora parasites which cause dragons to revert to a feral state, are poisoned by Dragonvine and Dragon Root plants make them go wild or if weaponize they disorientate them for a while, have a limited number of 'shots', as well as a blind spot. Most dragons appear to have a weak spot near their underbelly. Dragons can also be affected by diseases, such as Eel Pox (but only by eating eels). Scratching or pinching a specific spot at the bottom of a dragon's neck will incapacitate them and due to their acute senses, loud noises caused by clattering objects or loud noises from other dragons can be momentarily disorientated and cause them to see obscureness in their vision. This would also throw out their aim.
- Why Did It Have to Be Snakes?: All dragons (except for Typhoomerangs), are afraid of eels. This is a good reason, though. In Nine Reams, it is establish that dragons are also afraid of rubber Halloween snakes, which resemble to eels enough to scare the dragons.
Strike Class
Dragons who possess high speed and great intelligence. They are infamous for their often alarmingly fast and devastating attacks. General
- The Ace: They technically have very high stats compared to the other dragons.
- The Dreaded: These dragons are so powerful, they have a frightening reputation towards others.
- Genius Bruiser: See It Can Think and Super-Strength.
- It Can Think: They're capable of expressing emotions and learning new tricks to attack enemies.
- Lightning Bruiser: They're not only good at blasting powerful projectiles, but also, they're super fast at it too.
- Logical Weakness: Strike Class dragons have standard dragon weakness are vulnerable to Eels, Dragon Root, Blue Oleander, Dragonvine, and Grimora parasites. They unique weakness that are related to their unique physiology.
- Night Furies, Light Furies, and Night Lights are unable to fly if one of their tailfins are cut off.
- Skrills can't generate electricity if they are in water. This is due to water neutralizing electricity.
- Snow Wraiths are blind and due to relying on their thermal vision they can't see in their prey covered in snow (ironically their own environment which they use to hid in).
- Triple Strykes are the best close-range fighters but they can become overconfident and careless in a fight.
- Deathgrippers are not immune to their own venom.
- Super-Strength: Capable of lifting and knocking out larger dragons. Not to mention they have strong bite forces.
- Super-Speed: Not to the extent of the Speed Stingers but when it comes to flight, they outclass every other dragon.
Night Fury
Introduced: the How to Train Your Dragon movie.
The Unholy Offspring of Lightning and Death itself, Night Furies are fast, stealthy, and hit with enough firepower to blow the tops of catapult towers into cinders. They are the most feared dragons amongst the ranks of the Vikings. They belong to the Strike Class of dragons, emphasizing the classification's hard-hitting firepower and speed. They have a closely related subspecies with white coloration known as Light Furies.
- 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) and possibly the Light Fury 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 to stay with the riders and protect them from further harm.
- Always Accurate Attack: Their plasma blasts were described by Hiccup in the movie to "never miss", which was backed up in that almost all of their attacks (in the film) hit their mark. The fact that Toothless sometimes missed during the show is explained by the fact that the Night Fury is a night fighter and before the first film, always appears at night and picking off stationary objects like catapults.
- Catlike Dragons: They have characteristics very reminiscent of panthers and house cats.
- Cute Creature, Creepy Mouth: The species has a mouth full of small, sharp teeth, though they can retract them at will.
- The Dreaded: Vikings will gladly fight any of the other dragons, even ones that can swallow them whole, and have a long and impressive list of kills. If this one's screech is even heard? They run for cover screaming "NIGHT FURY! GET DOWN!". So much so that it was the only dragon listed where Vikings are advised to not even attempt to fight it.
- Endangered Species: Implied—they're extremely rare compared to other species of dragons, to the point of where up until Toothless came along, virtually no one had ever actually seen one (there wasn't even a drawing of it in the Dragon Manual that Hiccup was studying during his dragon training). In the second film, Eret admits that he thought Night Furies were "gone for good" and Valka (Hiccup's mother) notes that Toothless very well could be the last of his kind. The exact reason for the species' absence is never fully specified.
- Grimmel the Grisly, the main antagonist of the third/final film, is revealed to have hunted Night Furies into endangerment, claiming to have hunted every Night Fury except for Toothless—while there very well could be other Night Furies out there (outside of the Archipelago), Toothless is the only Night Fury ever actually seen in the (living) flesh.
- Eminently Enigmatic Race: Night Furies are the most feared of dragon species, precisely because they're the least known. They are too elusive to capture, and so swift and stealthy in their attacks that no one has lived long enough to study one.
- Expy: Fans of Monster Hunter notice a similarity between a Night Fury and a Nargacuga, and perhaps now, the Gore Magala.
- Game Face: When a Night Fury’s pupils contract while baring all their teeth, it is best to keep away from them.
- Genius Bruiser: Night Furies are the cleverest dragon species.
- Toothless has repeatedly shown to understand the 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 aggression), 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 the 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.
- Hero Killer: For the Vikings. That's why they are The Dreaded to them.
- Informed Flaw:
- In the tie-in ads and Defenders of Berk, it is mentioned that Night Furies only have six shots, similar to Gronckles. Toothless regularly fire dozens of shots in a fight.
- In the third film, Grimmel reasons that Hiccup hasn't taken the dragons North because Night Furiess has a weakness to cold and cannot survive in the cold. Toothless showed no aversion to the cold when staying in constant cold environments like Glacier Island in the tv series, at Valka's ice sanctuary in the second film, and in this film, both Toothless and the Light Fury are shown flying high in the clouds, where the temperatures would be very low.
- Also in the third film, Grimmel says that Night Furies cannot fly for long distances without resting because when traveling they need to take breaks on some islands before they can continue on (If a Night Fury is tired/sleepy they are easy prey to catch), Toothless has shown no aversion to being tired from flying from long distance, he still can be physically and mentally active and not be easy prey to catch by other predators.
- Innate Night Vision: Night Furies can see in the dark because they are adapted to flying at night, but they can’t see in pitch black areas forcing them to use Echolocation. However, only Toothless demonstrated these abilities and it is likely to weaken due to adapting to the daytime.
- Lightning Bruiser: They're called the unholy offspring of lightning and death, after all. As a Strike Class dragon (and the first one to be revealed, after all), they're incredibly fast, pack large amounts of firepower, and can take a fair bit of punishment as well.
- Mysterious Animal Senses: "We Are a Family" reveals that they can use echolocation.
- Metal Slime: Toothless is the only known Night Fury encountered so far, indicating either Last of Its Kind or their extreme rarity.
- Names to Run Away from Really Fast: Both its name and the Red Baron-status invoke this in the Vikings.
- Nocturnal Mooks: Their coloring and fighting approach indicates that this is invoked.
- Nothing Is Scarier: To an extreme extent—not a whole lot is really known about Night Furies, other than the fact that they're (typically/mostly) nocturnal and are considered dangerous to the point of being The Dreaded.
- The Quiet One: They are silent compared to most other dragons. Combined with their firepower, speed, and camouflage, they are downright nightmarish at night. One of the reasons the Vikings are downright scared of these dragons in particular is because you won't hear or know their presence until the start of their attack run.
- Red Baron: "The unholy offspring of lightning and death". In fact, the Night Fury is the only dragon in the movie to get a Red Baron-like title.
- Shock and Awe: Interesting that their dragon fire seems to give off this more than Playing with Fire. Also, if the battle with the Red Death in the movie is to go by, they have a concentrated blast so powerful they can topple the most gargantuan of dragons. The third movie shows that Toothless has the ability to summon lightning to strike himself, dealing cataclysmic damage to nearby foes and temporarily cloaking himself.
- Super-Senses: They can echo-locate much as bats and some birds can, enabling them to maneuver in complete darkness and helping explain their accuracy when attacking at night.
- Stuff Blowing Up: One of the reasons why they are feared. Their Breath Weapon attack is powerful enough to destroy catapults with ease and knock gigantic dragons down. As well as the fact that it can One-Hit Kill Vikings. Compare that to the fact that the other dragon's attacks seem to have a degree of survivability hammers home the fact that Night Furies are extremely dangerous to combat.
- Super-Strength: Surprisingly strong for its size—while it's obviously not the largest dragon species out there, Night Furies can wrestle the likes of a Monstrous Nightmare, a Whispering Death, a Razorwhip, and many other dragons into submission. They can also carry very heavy items, such as boulders or adult Vikings in flight for short periods of time.
- Super-Speed: One of the fastest breeds of dragons, so much so that nobody had ever seen what one looked before Hiccup injured Toothless. Only the Red Death is known to have matched or exceeded its speed, and Stormfly (a Deadly Nadder) only gets close because of Astrid's training and care of being feed chicken. It has been implied many times that Night Furies don't use their full speed and they are very fast even for average speed.
- In Fishlegs' Dragon Stats on the How To Train Your Dragon 2 DVD, he states that Night Furies can fly faster than the speed of sound. Hiccup and Toothless are seen doing this in the Dragons: Riders of Berk opening.
- Wave-Motion Gun: Their plasma blasts can do serious damage, toppling things like the Red Death or sinking ships in one hit. In the 2nd movie, it gives Drago's Alpha pause each time it hits, interrupting its attempts to fire its ice breath weapon and eventually even breaking off its left tusk.
- You Are Already Dead: The Book of Dragons mentions that if you encounter one, you are already screwed.
Skrill
Introduced: "View To A Skrill Part 1"
An elusive member of the Strike Class of dragons, the Skrill are known for their unique electrical abilities.
- Achilles' Heel: It cannot use its electricity when submerged underwater.
- Arch-Enemy: With Singetails.
- Ax-Crazy: According to the Book of Dragons, the Skrill is "Untrainable". Hiccup was willing to try, but he ultimately settled for just taking it out of the picture. Later on, however, the same individual proved capable of gratitude toward humans, though it remains to be seen if it's possible to train one. Viggo then shows that it is possible to tame one using metal objects.
- The Dreaded: The Skrill is said to be feared as much as the Night Fury. It is also the only dragon who can rival the full speed and firepower of the Night Fury.
- Early-Bird Cameo: Its first "appearance" is as a drawing in the Dragon Manual in the film (Hiccup even mentions its name). It isn't properly introduced until the show.
- Freeze-Frame Bonus: Some Skrills can be briefly glimpsed in the Hidden World.
- Harmless Freezing: It can survive decades frozen solid in a block of ice. Justified due to its efficient internal body temperature.
- It Can Think: It's a smart dragon, no doubt on that. When the riders were going to trick it into getting into the glacier through a small opening to freeze it again, it certainly knew better than to fall for it and sealed it.
- Lightning Bruiser: Being an electric Strike Class dragon, it is one of the few species that can match a Night Fury in speed and destructive power.
- Lightning Gun: Its breath weapon. The Skrill breathes out concentrated beams of powerful electricity. This means its attacks have limited homing ability towards metal and it can electrocute water to create a lethal surge.
- Monster in the Ice: It's found frozen in an iceberg — and unlike most other dragons in the franchise, that thing cannot be tamed. Unlike all the other dragons who are portrayed as quirky and highly intelligent animals, the Skrill is nearly demonic in how relentless it is in its assault, and how incredible its lightning Breath Weapon is. In the end, the only option Hiccup and Toothless have was to freeze it in an iceberg again.
- No-Sell: The electrical field it can generate can block Toothless' plasma blasts, though it needs to recharge to keep it up and it only demonstrated this while it was under the control of Dagur. According to Viggo its ability to control electricity also makes it immune to all the Singetail's fire attacks and gives it an inherent advantage against them, which is why it's the Singetail's only predator.
- Purple Is Powerful: One of two dragons that utilize an electrical/plasma Breath Weapon (the other being a Night Fury) and its colored violet.
- Ride the Lightning: It can call down a lightning strike and use it to get in the air in the blink of an eye.
- Shock and Awe: Thanks to unique organs and metallic scales, the Skrill can absorb electrical energy from the clouds and channel it through its body. It can erect a field of static electricity to ward off attacks or project it as a blast from its mouth.
- Shoot the Bullet: Can nullify other dragons' attacks this way using its own Breath Weapon.
- Spikes of Villainy: Is covered in spines. According to the series wiki, they're laced with metal and used to absorb lightning from the clouds.
- Undying Loyalty: While they prefer to be free, Skrills displays immense loyalty towards its trainer, willing to fight alongside them even in the face of death. This was demonstrated in "Triple Cross", when the Skrill refused to leave Viggo's side despite the latter instructing him to do so.
- Your Size May Vary: The Skrill is shown to be at least around the same size as Toothless in the tv series. However, their cameos in the third film show them being smaller than Gronckles. Things get more inconsistent in The Nine Realms, where one individual was shown to at least be bigger than a Monstrous Nightmare. However, this can be excused if one considers that Skrill to be a Titan Wing.
Snow Wraith
Introduced: "Dragon Eye of the Beholder Part II"
An erratic Strike Class dragon that lives in glaciers.
- Big Ol' Eyebrows: They have long point brows above their eyes.
- An Ice Person: To the point of hibernating during the summer.
- The Dreaded: After an ill-fated voyage that killed two Vikings, Gothi is hesitant to go back and find it.
- Fast Tunnelling: It can dig through ice and snow pretty quickly.
- Icy Blue Eyes: It’s an ice-themed dragon with piercing blue eyes.
- Lightning Bruiser: Like all the other dragons of its class, it packs both the speed and power to take down virtually any opponent - especially if it's in a blizzard, where it can use its stealth to further boost its fighting prowess.
- Magic Missile Storm: It's not really magic, but its Breath Weapon fires frost in rapid succession.
- Night-Vision Goggles: Sort of; its eyes see differences in temperature instead of actual color vision, allowing it to see in a blizzard.
- No-Sell: Its thermal vision isn't affected by the Chameleon Camouflage of Changewings or Featherhides, making their usual strategies useless against a Snow Wraith.
- Stealth Expert: Fighting it on its home turf is a terrible idea since its white scales let it blend into the surrounding snow.
Triple Stryke
Introduced: "Stryke Out"
An extremely dangerous Strike Class dragon that specializes in melee combat.
- Animal Motifs: The tails and claws are strongly reminiscent of a scorpion, while the coloration seems more like a wasp.
- Arrogant Kung-Fu Guy: Similar to Sharp Class dragons, they're described as being very vain and overconfident due to their incredible power, which is a weakness that can be exploited.
- The Berserker: Its fighting style seems simply based around attacking as fast and as often as possible, with little regard given to the defense. This is what gets Sleuther chosen as a ride dragon by Dagur, who shares its Blood Knight and all-out attacking tendencies.
- Beware My Stinger Tail: Three tails that end in scorpion stingers. It can braid them together to act as a single tail.
- Blood Knight: They're described as being incredibly violent and battle-hungry even from birth.
- Bright Is Not Good: It has a bright yellow and black color scheme and has an incredibly violent disposition.
- Lightning Bruiser: It's a Strike Class dragon, after all. The Triple Stryke is very fast, exceptionally durable, and has incredible strength in its physical strikes - although, in contrast to the other Strike Class dragons, it specializes in close-range combat rather than ranged attacks.
- Multiple-Tailed Beast: Three scorpion-like tails, which can strike individually, or all at once.
- Poisonous Person: Each one of its three tails holds a different type of venom. One numbs the target, one disorients them with hallucinations, and one induces agonizing pain.
- Power Pincers: Notably has large pincers instead of conventional claws.
- Prehensile Tail: Sleuther was able to throw Toothless around with just one of his tails.
- Scary Scorpions: Its body shape resembles that of a scorpion, and it's a very powerful dragon.
- World's Strongest Man: Downplayed. In the fighting arena that Ryker put Sleuther in, it won all its battles so efficiently that people were beginning to get bored of them. It quickly learned a lesson in humility after Toothless soundly defeated it.
Light Fury
Introduced: How to Train Your Dragon: The Hidden World
A Strike Class dragon, an elusive subspecies to the Night Fury that has the ability to cloak itself with its Breath Weapon.
- Catlike Dragons: They behave very similarly to cats, perhaps even more than a Night Fury.
- Chameleon Camouflage: The Light Furies' ability to disappear is caused by flying through their fireballs, which heats their scales and enables them to become reflective of their surroundings.
- Eminently Enigmatic Race: They are just as elusive as Night Furies. They are apparently limited to the Hidden World thanks to their skittishness towards other creatures and dragons.
- Pale Females, Dark Males: Averted, at first it seems that the Light Furies are the female equivalent of the Night Fury in a case of Bizarre Sexual Dimorphism, but they're a subspecies instead, with males of similar coloration to the females.
- Underground Monkey: Due to being closely related, Light Furies are basically Night Furies with white skin and smoother features.
Deathgripper
Introduced: How to Train Your Dragon: The Hidden World
A fearsome Strike Class dragon that travels in packs and preys on other dragons. They possess tusks, pincers, and a clubbed tail with a venomous stinger on its end.
- Beware My Stinger Tail: The tail of the Deathgripper is tipped with a stinger filled with venom that can sedate other dragons.
- Brainwashed and Crazy: Their venom is capable of making dragons susceptible to commands.
- The Dreaded: The Dragon Riders and all dragons, including the large Rumblehorn and Fearless Infant Scuttleclaws are afraid of these dragons.
- Handicapped Badass: At least one of Grimmel’s Deathgrippers has a blind left eye, yet is just as ferocious and competent as the rest of the group.
- Hoist by His Own Petard: Grimmel uses their own venom to control a small pack of Deathgrippers.
- Hollywood Acid: Deathgrippers spit highly flammable acid.
- I'm a Humanitarian: They prey on other dragons and DeBlois refers to them as "vicious dragon killers".
- Power Pincers: They have pincers on their forelegs, similar to that of a mantis.
- Red and Black and Evil All Over: These dragons have black scales on their upper bodies and red scales with black stripes on their underbellies. They are also used by the villainous dragon hunter Grimmel to help him on his hunting expeditions. Dean Deblois says they were partially based on black widow spiders.
- Scary Scorpions: They are venomous, scorpion-like dragons that prey on other species.
- Scary Teeth: They have very long, retractable tusks.
- Slave Mooks: Grimmel forces them to act as his personal dragon killers using head collars that inject their venom into their wearers.
- Super-Strength: On paper, Deathgrippers are considerably stronger than your average dragon. The official dragon statistics show that their "attack" stat is third-highest at 27.note Additionally, their jaw strength is listed at 16, whereas most dragons' jaw strength is in the single digits.
Night Light
Introduced: How to Train Your Dragon: The Hidden World
A Strike Class dragon, a hybrid between a Night Fury and a Light Fury.
- Artistic License – Biology: In The Nine Realms, Night Lights are shown to still exist well into the present day. Not only are hybrid animals unable to breed, but the darker coloration inherited from Toothless would not be present in future generations as they would only have other Light Furies to breed with.
- Catlike Dragons: Being a mix of a Night Fury and Light Fury, they are very reminiscent of cats. Their black and white patterns even bring tuxedo cats to mind.
- Chameleon Camouflage: Night Lights inherit the Light Fury's ability to temporarily camouflage themselves by flying through their own Breath Weapon.
- EMP: They can send out an electromagnetic pulse that briefly shorts out all electronics.
- Shock and Awe: They can fire blasts of electricity from their mouths, inherited from their Night Fury parent.
Stoker Class
Dragons that take their species' mastery of flame to another level and utilize fire in many unique and lethal ways. Personality-wise they are often aggressive and fearless. General
- Playing with Fire: They use firepower more often than most dragons for their main attacks.
Monstrous Nightmare
Introduced: the How to Train Your Dragon movie.
The iconic Stoker Class dragon, Monstrous Nightmares are the largest of the common dragons and are well-known for their violent streak and their copious firepower.
- Blood Knight: It was said in the DVD commentary that even though all the dragons will fight, the Monstrous Nightmare fights simply for the joy of fighting.
- Burning with Anger: Whenever these dragons are upset, they burst into flames.
- Expy: A Monster Hunter fan with a keen eye might notice several similarities between this dragon and the ferocious King of the Skies, Rathalos.
- Defeat Means Friendship: In the TV series, at least, this seems to be the most effective method to earn their friendship. In the film, Hiccup can tame one with far less effort.
- Hair-Trigger Temper: It is very easy to piss of a Monstrous Nightmare.
- Incendiary Exponent: Monstrous Nightmares attack after setting themselves on fire.
- Names to Run Away from Really Fast: Most dragons have these, but theirs is a particularly extreme example.
- Optional Stealth: Monstrous Nightmares are shown to be almost stealthy like a Deadly Nadder. However as seen in As shown by Hookfang in "Cast Out, Part 1", and "Not Lout", Monstrous Nightmares tend to stomp loudly on the ground when they are walking, which gives their prey a chance to escape.
- Super Spit: All There in the Manual sources state it coats itself with flammable spit, which is how it lights itself on fire. In a moment of brilliance, Snotlout (who rides a Nightmare) comes up with the idea of harvesting this spit (as "Monstrous Nightmare Gel") to use as tinder, an idea Hiccup later expands on.
- Wreathed in Flames: Once on fire.
Terrible Terror
Introduced: the How to Train Your Dragon movie.
Terrible Terrors may be small, but they are no less dangerous than their larger kin amongst the dragons.
- Instant Messenger Pigeon: Hiccup and Fishlegs turn them into this in "Appetite for Destruction".
- Killer Rabbit: They are about the size of a medium-sized cat. That won't stop them from attacking larger foes. The fact that, according to the Book of Dragons short, they're social dragons who tend to hang out in dozens-strong packs, makes them even more dangerous.
- Mythology Gag: They literally look like the book's version of Toothless.
- Pintsized Powerhouse: Like all dragons, it is stronger than its size implies.
- Ridiculously Cute Critter: Especially when one sleeps next to Hiccup because he gave the dragon a fish.
- Shoulder-Sized Dragon: Terrible Terrors are about the size of house cats.
- Team Pet: Due to its size, there's no one small enough to ride one. That doesn't mean they aren't liked all the same. "Worst in Show" has the riders each adopting one in a competition to see who the best trainer is. No one wins since they get distracted by an attack from Alvin.
- Hiccup and Fishlegs have plans to use them as carrier pigeons to deliver messages to Berk from far away, calling it "Air Mail".
- Zerg Rush: While vicious on its own, a single Terrible Terror is not too much of a threat. But they are social creatures and tend to work in packs.
Red Death
Typhoomerang
Introduced: "The Terrible Twos" First appearance of a dragon not from the movie.
Typhoomerangs have a unique ability during flight: they rotate (by analogy with the typhoon/ boomerang) at high speeds, zooming through the air. Though, as they rotate, they seem to pop off the objects around them, making them extremely dangerous. The ash from their fire breath leaves a distinctive burn on the ground. The ash apparently acts as a fertilizer; flowers will grow in the burn mark afterward.
- Giant Flyer: They can grow to be as tall as a conifer tree. They also boast an impressive wingspan.
- No-Sell: Can eat eels that are poisonous to all other dragons.
- Power-Up Food: As stated above, unlike most dragons, Typhoomerangs can eat eels, which is something their Breath Weapon is dependent on. If a Typhoomerang runs out of fire breath, it can just eat some eels to regain it.
- Ring of Fire: They hunt by surrounding their prey with fire. The flames they exhale are also tornado-shaped, meaning an agile enough dragon can fly through the center without touching them.
- Spectacular Spinning: Its main way of breathing fire.
- Super-Speed: It can get a speed boost by igniting itself like a Catherine Wheel firework.
- Wreathed in Flames: As noted, this is the catalyst for its Super-Speed. Not only does this make it fly faster, but it also turns it into an airborne, spinning saw blade.
Fireworm
Fireworm Queen
Average Fireworm
The Hidden World redesign
Introduced: "Portrait of Hiccup as a Buff Man"
Small Stoker Class dragons, Fireworms are lizard-sized and lizard-like dragons that rely on their fiery skin to shield them from bigger enemies. They swarm in large numbers. Their Queen, however, is massive and can breathe fire like regular dragons.
- Art Evolution: The Fireworms that appear in the third film have been redesigned to have visible pupils, four pairs of legs, and stubby spines going down their back.
- Breath Weapon: The little ones don't seem to have it, but the Queen does.
- Canon Immigrant: They are the only dragons created exclusively for the tv series to physically appear in the main movies, specifically the third film.
- Incendiary Exponent: Said to burn with the heat of the sun. It is a miracle that Tuffnut’s hand has no lasting injuries when he picks one up that burns in his hand.
- Ironic Fear: Fireworms are apparently afraid of fire. This is because burning fire indicates danger to them.
- Large and in Charge: The Fireworm Queen is larger than most regular dragons, about halfway between the Monstrous Nightmare and the Screaming Death.
- Mama Bear: Do not mess with the Queen's nest if you want to live.
- Monochromatic Eyes: All the Fireworms have eyes with no pupils. Their redesigns in the third movie give them pupils though.
- Mythology Gag: Snotlout’s dragon was named Fireworm in the original book series.
- Prehensile Tail: The Queen was able to pick up Hookfang with her tail.
- Shoulder-Sized Dragon: The little Fireworms are about the size of rats.
- Vertebrate with Extra Limbs: They have five pairs of legs. Along with their wings, that makes twelve limbs.
- Zerg Rush: You will get more than just third-degree burns when thousands of little Fireworms start to swarm towards you.
Night Terror
Introduced: "When Darkness Falls"
A species of dragon found by Hiccup's group, similar to Terrible Terrors but slightly larger. They make up for their lack of size by flying in formations to make themselves look like one very large dragon. There are two notable subspecies: a white-colored, subterranean variant that is sensitive to light, and a red-colored, volcanic variant that lives on Defenders of the Wing island.
- Animal Espionage: After Hiccup's group help them out, the Night Terrors essentially volunteer to be sentries for the Edge.
- Awesomeness by Analysis: The entire pack can perfectly imitate a new shape simply by observing it for a few moments. So far they've used this ability to pay homage to Toothless in one episode, then they use this ability to impersonate the Fireworm Queen in a later episode to draw the Fireworms away from their island.
- Decapitated Army: The pack follows an alpha and if the alpha is gone then the others will be easily take down the whole flock.
- Feed It with Fire: An ability that the volcanic subspecies have demonstrated.
- Red Eyes, Take Warning: The volcanic Night Terrors have glowing red eyes, though subverted as they're not malevolent.
- Synchronized Swarming: As long as the alpha is there to guide them, they can swarm to form a larger approximation of themselves or mimic other dragons.
- Weaksauce Weakness: Without the alpha, they cannot swarm and become vulnerable to predators.
Singetail
Introduced: "Turn and Burn"
A large Stoker Class dragon that launches fireballs from its tail as well as its mouth and can even jet fire from its underside. Their combat abilities are among the most versatile of any dragon and due to this, they become the mounts the Dragon Flyer Krogan specifically seeks to use.
- Abnormal Limb Rotation Range: Its eyes are exactly like a chameleon's, being able to move independently of each other and point behind it. This makes them difficult to surprise or sneak up on
- Acrophobic Bird: One of their few weaknesses is that they avoid flying too high up into the air. If forced to fly beyond a certain altitude they become disoriented and may outright crash land.
- Animal Motifs: The Singetail's physical appearance greatly resembles a chameleon, a thorny lizard, and a horned lizard combined.
- Arch-Enemy: With Skrill. According to Viggo, it is the only dragon species they have a disadvantage against as its electric field can neutralize all their fire attacks.
- Black Bead Eyes: Singetails have small eyes that are structured in a cone-shaped eyelid like a chameleon.
- Distress Call: Lights signal fires to call for backup.
- Fog of Doom: Singetails are shown to be very reluctant to fly into a heavy fog. However, this weakness does not seem to affect all Singetails, as Krogan's Singetail had no problem flying through the fog, though it was more force to go in than willing.
- Giant Mook: Krogan rides one several times the size of the others.
- Playing with Fire: Can breathe fire, fling fireballs from its tail, and vent fire from its underbelly.
- Recoil Boost: The flame vents on its underbelly can be used to give it a short boost of speed.
- Spread Shot: Can fling up to four fireballs from its tail at once.
- Vertebrate with Extra Limbs: Eight limbs this time; four legs and four wings.
- Zerg Rush: One Singetail's distress signal can summon dozens of others.
Shadow Wing
Small Shadow Wing
Large Shadow Wing (with Small Shadows clinging to its wings)
Introduced: "The Longest Day"
The aircraft bomber of dragons, the Shadow Wing is never on its own. The smaller dragons are seen first, herding prey into the jaws of one larger dragon that hides the rest of the pack in the shadows of its wings. They are two separate species that work together to give each other protection and food.
- Brains and Brawn: The small Shadow Wings are coordinated attackers while the large Shadow Wing is relied on as the muscle that brings down the prey.
- Fireballs: The smaller Shadow Wings' shots are fireballs of molten lava that bounce several times before exploding like fireworks.
- Giant Flyer: The large Shadow Wing is massive enough to almost fit Toothless into its mouth.
- Mighty Glacier: The larger Shadow Wing is this, it makes up for its lack of speed by having the smaller Shadow Wings cling onto its wings and unleash More Dakka.
- One-Shot Character: Only appears in a single episode. They at least appear in some tie-in games though.
- Super-Scream: The larger Shadow Wing can roar loud enough to stun potential prey, and it also calls back any hidden smaller Shadow Wings to its location.
- Wounded Gazelle Gambit: How the smaller Shadow Wings hunt. One of them pretends to be injured to lure in potential prey looking for a meal (or any human wanting to investigate) before the rest of the pack ambushes them.
- Zerg Rush: The smaller Shadow Wings make up for their lack of presence by grouping up and attacking from all directions.
Hobblegrunt
Introduced: How to Train Your Dragon 2
A frilled Stoker Class dragon that changes color based on mood.
- Chameleon Camouflage: Played straight with real-world chameleons in that the color changes of the Hobblegrunt are based on mood, as opposed to the camouflage of the Changewing that is based more on Hollywood Chameleons.
- Colour-Coded Emotions: The color of their scales change to reflect their current mood.
- Curious as a Monkey: When these dragons are purple, it means they are curious or interested in something.
- Emotion Bomb: Their color changes can also alter the mood of other dragons around them, allowing them to pacify perturbed dragons.
- The Empath: Their frill allows them to detect the moods of surrounding dragons, as well as changes in temperature or barometric pressure. This allows Gruff, the blinded Hobblegrunt in Valka's care, to navigate its surroundings normally.
- Hate Plague: They can also use their mood-altering abilities to rouse fellow dragons in their nest into aggression for defensive purposes.
- Perpetual Smiler: The way their lower jaw curves up with their teeth exposed make Hobblegrunts look like they are always smiling.
- Red Is Violent: Apparently, if the Hobblegrunt turns red, you're in for quite the beatdown.
- You Don't Look Like You: The Hobblegrunts in the School of Dragons mobile game actually look like Threadtails, implying their names and models have been mixed up during the games’ production.
Threadtail
Introduced: How to Train Your Dragon 2
A Stoker Class dragon that secretes poison through its skin.
- Acquired Poison Immunity: Averted, the Threadtail is allergic to its own poison to a lesser degree than other species, causing it to suffer only from extreme itchiness whenever it utilizes its own defense mechanism.
- Living Prop: Most of them stay in the background throughout the sequels and are not very noticeable.
- Long Neck: They have long slender necks.
- Poisonous Person: Like the Slitherwings, Threadtails secret poison through their skin, but only when defending themselves, as excreting it constantly, due to their aforementioned allergy, would likely be unending torment.
- Weaksauce Weakness: Are, again, allergic to their OWN poison.
Flame Throwers
Introduced: "Ride or Die"
A Stoker Class dragon that travels in packs and prey on other dragons.- Animal Motifs: Clearly takes inspiration from hyenas.
- Fangs Are Evil: They have big teeth sticking out of their mouths and are not docile in the slightest.
- I'm a Humanitarian: Since they first appeared they are shown to prey on other dragons.
Sky Torcher
Snowtail
Introduced: "The Decoy"
Small dragons inhabiting the Ice Realm.- Irony: Snowtails are Stoker Class dragons that live in the Ice Realm.
- Living Prop: They are not given any focus in the episodes they appear in and just fill the ranks of dragons in the Ice Realm.
- Reused Character Design: They look pretty similar to Death Songs, which may imply they are closely related species.
Boulder Class
Mostly big and bulky dragons whose abilities relate to stone and great strength. They tend to feel more at home on the earth or even under it. They are usually even-tempered and friendly even before being tamed. General
- Dishing Out Dirt: They're basically dragons who do anything related to the ground. Like digging and eating rocks.
- Extreme Omnivore: They can eat rocks.
- Muscles Are Meaningful: They are large and strong. Capable of lifting heavy objects.
- Super-Strength: As if Muscles Are Meaningful wasn't enough.
- Super-Toughness: They're highly durable dragons.
Gronckle
Introduced: the How to Train Your Dragon movie.
The iconic Boulder Class dragon, Gronckles are relatively small and sluggish dragons, but extremely tough and strong.
- Dumb Muscle: Gronckles are generally lazy and easygoing, but rouse them, and they're as temperamental and direct as an angry rhino.
- Ear Fins: While Gronckles don’t live underwater, they possess these kind of ears.
- Extreme Omnivore: It can eat rocks. And its Breath Weapon depends on this fact.
- Limit Break: In the movie, it is stated they only have enough fuel for six shots. Meatlug and other Gronckles can be seen firing more shots during the series. However, this is due to the rocks they primarily eat that act like Power-Up Food to recharge their shot limit.
- Magma Man: The Gronckle is one of the few dragons that doesn't directly produce fire. Instead, it gobbles up rocks and mouthfuls of soil and then heats them to a molten state inside its belly. This superheated rock is then spat out at targets as distinctive fireballs. With the right combination of rocks, it can also produce Gronckle iron, a lightweight metal that is tougher than period iron and excellent for weapon and armor crafting. Though whether it's a real material under a different name or not is unspecified.
- Mighty Glacier: The slowest of the rider-sized dragons, but its magma attack is pretty powerful. It can even stagger a Screaming Death simply by ramming into it and keeps coming back for more!
- Mix-and-Match Critters: The Gronckle looks like a cross between a bulldog, a bumblebee, and a toad.
- Mundane Utility: Amongst the dragons, Gronckles have the most of this. They can hover in place, they can ingest rocks to make materials (for example, with sandstone they can make glass), and can carry significant loads while flying.
- No-Sell: Immune to Dragon Root (an herb that causes all other dragons to go crazy).
- Ridiculously Small Wings: Gronckles have wings disproportionately smaller than the rest of their body, so they make up for it by beating them really fast.
Whispering Death
Introduced: "What Flies Beneath".
A rare and deadly member of the Boulder Class, the Whispering Death is a subterranean species of dragon that uses its wide mouth, spike-covered sinuous body, and six rows of rotating teeth to bore through the ground and come up from below when pursuing prey.
- Awesome Mc Cool Name: Tuffnut certainly thinks so.
- Blank White Eyes: Though it isn't blind.
- Dark Is Evil: One of the scariest looking dragons has also been one of the cruelest, with the first one harassing the entire village of Berk, including eating livestock, out of a feud with Toothless and the second one ending up being used by Alvin the Treacherous. This perception changes later in the series when it's shown that they're not all bad after all.
- Early-Bird Cameo: First mentioned in the Dragon Manual in the first film, but didn't make an actual appearance until Riders of Berk.
- Flying Seafood Special: Thematically invoked; despite being a mostly subterranean creature, the Whispering Death is still quite capable of flight.
- Lean and Mean: They're the archetypal 'villain' dragons, with long, limbless, eel-like bodies.
- More Teeth than the Osmond Family: Six rows of rotating teeth. Between this, their oversized, ball-like heads, and their hostility, they're a draconic Langolier.
- No-Sell: Unaffected by Dragon Nip (an herb that has a calming effect on all other dragons), just in case they weren't hard enough to deal with.
- Ridiculously Small Wings: Whispering Deaths have rather small wings compared to their long serpentine bodies. To make up for this, they twirl their bodies around as they fly.
- Ring of Fire: It breathes concentric rings of fire, with a normal fireball running through them.
- Spectacular Spinning: They have rotating jaws and their tails move in a circular motion while in flight.
- Spikes of Villainy: One of the archetypical "evil" dragons and the one with the most spines per surface area.
- Spike Shooter: Like the Deadly Nadder, only from virtually every point on its body.
- Tunnel King: This is its signature ability and mode of travel.
- Weakened by the Light: They retreat from direct sunlight, though even mild cloud cover is sufficient for them to go outside.
Screaming Death
Catastrophic Quaken
Introduced: "Quake Rattle and Roll"
A large Boulder Class dragon that can curl and roll its body like a giant ball.
- Ear Fins: Just like the Gronckle, Quakens have fins for ears.
- Flower Mouth: It has a lower jaw that splits down the middle and can separate into two jaws.
- Gentle Giant: Befriend the Quaken, and it becomes this.
- The Juggernaut: When it's rolling, it can't be stopped. The only thing to do is get out of the way.
- Mighty Glacier: It can tank direct hits from Toothless' plasma blast without slowing down.
- More Teeth than the Osmond Family: A Quaken has two lower jaws, splitting down the middle. Both parts have their own set of boulder-crushing teeth.
- No-Sell: Marble can withstand attacks from all other dragons except this one.
- Rolling Attack: How it moves through its tunnels, also likely squishing anyone unfortunate to be in them.
- Shockwave Stomp: It can smash into the ground hard enough to rattle opponents in the air.
- Spikes of Villainy: Quakens have spikes on every square foot of their topside. Subverted when it turns out to not be villainous.
Hotburple
Introduced: How to Train Your Dragon 2
A lazier, fussier member of the Gronckle's family tree.
- Beware the Nice Ones: The easiest way to motivate a Hotburple is to make it angry. If it was casually destructive before, it'll prove that intentional destructiveness is so much worse.
- Ear Fins: Just like the Gronckle, Hotburples have fins for ears.
- Exhausted Eye Bags: They all have this look at all times. Combined with their mouth, it makes for a weirdly cheerful sleepy expression.
- Extreme Omnivore: If it's not sleeping, a Hotburple is most likely going to be chowing down on rocks and metal.
- Lazy Dragon: Laziness is this species' hat, and if Grump is any indication, they'll even fall asleep while flying. And then they'll continue flying because they've adapted to doing so while asleep.
- Magma Man: Much like their Gronckle cousins, Hotburples eat rocks for minerals and to fuel their Breath Weapon. What sets them apart is that they'll also eat metal, and actually prefer to do so.
- Metal Muncher: Their jaws are strong enough to tear through dragon proof metal and are capable of digesting iron.
- Mundane Utility: Anything a Gronckle can do, a Hotburple can also do, be it hover in place or forging materials. They're just harder to motivate into doing so.
- No-Sell: All those dragon-proof metals developed by the dragon hunters are just another meal to a Hotburple. Now, if only they were properly motivated...
- Underground Monkey: They are very similar to Gronckles, yet have some minor differences. They eyes are on the sides of their heads, they are bulkier in terms of body mass, and they are extremely slow and lazy.
Eruptodon
Introduced: "Defenders of the Wing Part 2"
A huge Boulder Class dragon that lives in volcanoes, feeding off of the lava flow.
- Bruiser with a Soft Center: When it is not fighting for self-preservation, it is actually quite docile.
- Gentle Giant: It protects anyone friendly to it, as the Defenders of the Wing have proven.
- Horror Hunger: What it eats (rocks and lava) isn't horrifying, but the fact that it can fall into a feeding frenzy that results in an exploding volcano is.
- Lava Adds Awesome: Not only does it eat lava continuously, but its skin looks like cooling lava.
Sentinel
Introduced: "A Matter of Perspective"
Gargoyle-like dragons that pretend to be statues. Entirely blind, they stand guard over the final dragon resting place of Vanaheim.
- Blow You Away: Their Breath Weapon consists of a powerful blast of air that can force a flying dragon down or redirect projectiles back at them.
- It Only Works Once: They adapt to the strategies and abilities of any dragon that comes to Vanahiem and new tactics won't work a second time.
- Handicapped Badass: They are completely blind but serve as both caretakers and guardians for Vanahiem.
- Our Gargoyles Rock: Their general appearance is gargoyle-like and they even sleep in a way that makes them resemble statues.
- Nobody Here but Us Statues: They sleep standing up and completely still which due to their stony skin are easily mistaken for carved statues.
Shovelhelm
Introduced: How to Train Your Dragon 2
An intelligent and hard-working Boulder Class dragon that uses its own head as a tool.
- Animal Motifs: They are very similar to beavers because they are the builders of the dragon world. They even have flat fins on their tail reminiscent of a beaver’s tail.
- Awesomeness by Analysis: They prefer to analyze a situation before acting out.
- Mundane Utility: Following the events of the second movie, the Shovelhelms that have relocated to Berk are being used for digging and hammering.
- One Shovelhelm is shown in the third film breathing fire to cook a Viking's fish.
- The Reliable One: Diligently work at tasks set to them and are known to seek out others in need of assistance, be they Vikings or other dragons.
- Use Your Head: Shovelhelms, as the name implies, use their pointed chins to dig out holes for dragon nests or their Viking companions. Their armored heads are also used as hammers.
Snafflefang
Introduced: How to Train Your Dragon 2
A playful and sturdy Boulder Class dragon that feeds on geodes.
- Beware My Stinger Tail: Has the trademark tail bludgeon of its Gronckle and Hotburple cousins, but the spikes dotting it are longer and sharper.
- My Species Doth Protest Too Much: Extremely nimble and active, a rarity among the normally slow and lazy Boulder Class dragons.
- Trademark Favorite Food: Geodes, which it crushes with its very sharp teeth.
- Weaksauce Weakness: Their diet of geodes restricts them to certain habitats, making them VERY easy to locate for dragon hunters, as well as very easy to bait into traps. Valka's Snafflefang in the second film, Lump, lost its leg in this manner.
Crimson Goregutter
Introduced: How to Train Your Dragon: The Hidden World
An enormous Boulder Class dragon with moose-like antlers.
- Beware the Nice Ones: Crimson Goregutters are generally docile until they are provoked.
- Casually Powerful Giant: When the Crimson Goregutter accidentally backs up into a statue on Berk, the statue tips over and causes many buildings to fall on top of each other into the sea.
- Gentle Giant: One of these massive dragons grows fond of the baby Gronckle Fishmeat.
- Giant Flyer: They are almost 20 feet tall and have broad wings to carry their bulky bodies while in flight.
- Giant Foot of Stomping: When the rescued Crimson Goregutter is freed from a cage during the final battle of The Hidden World, it manages to step on one of the dragon hunting soldiers. The camera pans up before we can see the man get stomped on, but the implications are very clear.
- Endangered Species: Supplementary material states that they are very rare dragons facing extinction.
- Horn Attack: They spew lava onto their antlers, setting them ablaze before charging.
- The Marvelous Deer: It's a huge dragon with moose-like antlers.
- Use Your Head: Grimmel’s fort is sent tumbling down when this dragon flys into the tower and rams it.
Fault Ripper
Magma Breather
Introduced: "Magma Breather"
A pig-like dragon that wallows in the magma it spews.
- Animal Motifs: Pigs. A pig-like nose, springy tail, boar tusks, and rolling around in magma all add up to a dragon that might as well be a wild hog.
- Ear Fins: They have little ones on the sides of their heads.
- Magma Man: It eats magma, and regurgitates it to ward off foes, or make a nice, superheated puddle to relax in.
- Ridiculously Small Wings: It’s wings are extremely tiny, which contrasts with its comically fat body.
- Suspiciously Similar Substitute: They are fat dragons that breathe molten rock and have large tusks sticking out their mouths with tiny ear fins and small wings. This dragon has a lot of similarities with Gronckles.
Tracker Class
The newest class of dragon, replacing the Fear class. All of these proud dragons are defined by their unmatched tracking abilities, sharp senses, and great cleverness. General
- The Nose Knows: They use smelling to track their targets.
Deadly Nadder
Introduced: the How to Train Your Dragon movie.
The Deadly Nadder was originally the iconic Sharp Class dragon, a category of dragons distinguished by their natural arsenal of spines. However, after the events of Gift of the Night Fury and the discovery of the Tracker Class, they were categorized into this new class which is distinguished by sharp senses with Nadders being noted to be able to detect spies from upwards of a hundred meters away. Amongst the most avian-looking dragons, these vainglorious dragons spend much of their time preening themselves.
- All Flyers Are Birds: Nadders are one of the most bird-like dragons. They attack their prey with their feet like a bird of prey, preen themselves constantly, and perform a mating dance similar to that of a blue-footed booby.
- Attack Its Weak Point: The primary weak point of the Deadly Nadder is the blind spot in front of its head. To correct for this, it will attack anything that even gently touches the nose or hears something it cannot see. As Gobber said, "Blind Spot, yes. Deaf spot ... not so much." That said, trainers who build up a strong rapport with their Nadders are allowed to touch them there.
- Dinosaurs Are Dragons: Aside from the obvious bird comparison, the Nadders' body plan, gait, and facial structure also bring non-avian theropods to mind.
- Fragile Speedster: They are capable of matching speed with a Night Fury, but don't have the stamina or durability to keep up with one.
- The Fighting Narcissist: Deadly Nadders are extremely vain, evidenced by the generous amounts of time spent preening themselves.
- Our Wyverns Are Different: They share several characteristics with classical wyverns, being very birdlike, four-limbed bipedal dragons with tails bristling with (admittedly non-poisonous) blades.
- Spike Shooter: Deadly Nadders can shoot spikes from their tail with frightful accuracy. These spikes were the original reason for it being iconic for the Sharp Class before the Tracker Class was discovered between movies.
Rumblehorn
Introduced: How to Train Your Dragon 2, chronologically introduced first in "Crushing It."
Discovered in the episode "Crushing It," of Race To The Edge, but first seen in How To Train Your Dragon 2, the Rumblehorn also resulted in the discovery of a new classification of dragons: Tracker Class. Described as the bloodhounds of dragons, Rumblehorns serve as the iconic dragon for the class alongside the former Sharp Class iconic, the Deadly Nadders.
- Gentle Giant: Rumblehorns appears to have an instinct to protect, given that a wild Skullcrusher did his best to save humans and dragons he didn't know from a tsunami.
- Mix-and-Match Critters: Described as a truffle pig mixed with a rhino and a scarab beetle.
- Scarily Competent Tracker: Called the 'Bloodhound of Dragons' for a reason - Skullcrusher, Stoick's dragon after letting Thornado go, was able to track down Toothless to the Glacial Sanctuary despite no land trail and the scent is coming from a helmet that had been in the water for some time.
- Super-Strength: Rumblehorns can break giant rock pillars by smashing into them, and look no worse for wear afterward.
- Tough Beetles: They are tough dragons with beetle-like plates covering their necks.
Thunderclaw
Introduced: How to Train Your Dragon 2
A free-spirited Tracker Class dragon found in herds.
- Animal Stampede: Lives in groups for protection, and will often resort to this tactic as a means of defense.
- Armored Dragons: Most of the dragons in Drago’s army are made up of Thunderclaws wearing body armor.
- Good Colors, Evil Colors: The Thunderclaws in Valka’s dragon sanctuary come in bold and bright colors. The ones in Drago Bludvist’s army are colored a dull grey.
- Hoist by His Own Petard: They don't fly while stampeding, a behavior that is easily exploited by dragon trappers.
- Technicolor Fire: They can breathe orange and/or green fireballs.
- The Nose Knows: Has an extremely powerful sense of smell, like many Tracker Class dragons.
Snifflehunch
Introduced: How to Train Your Dragon 2
A curious Tracker Class dragon with not much of a sense of boundaries.
- All Animals Are Dogs: Pestbud sniffs Toothless’ rear to get more familiar with him.
- Evil-Detecting Dog: Snifflehunches can use their sense of smell to tell if someone is good or bad based on the hormones they give off.
- No Sense of Personal Space: Valka's Snifflehunch, Pestbud, sniffs up Toothless' rear like a dog, much to the latter's irritation.
- The Nose Knows: Has an extremely powerful sense of smell that it uses to identify friends and foes.
- Sneeze of Doom: Literally SNEEZES fire as part of its Breath Weapon.
Windgnasher
Introduced: How to Train Your Dragon 2
A hunch-backed Tracker Class dragon.
- An Ice Person: Breathes out blasts of icy wind and has a "blizzard" attack, a very powerful icy blast with whirling winds, which comes out in concentrated rings. Despite this, they are still shown to breathing fire too.
- Beware My Stinger Tail: Has a large bludgeon on its tail, even if no individuals are seen using them.
- The Nose Knows: Has an extremely powerful sense of smell that can follow targets across the Barbaric Archipelago and supposedly even beyond.
- The Noseless: Interestingly, Windgnashers lack visible nostrils despite being reliant on their sense of smell.
Gembreaker
Introduced: "A Hole New World"
A large rhino/beetle-like dragon with a crystalline horn.
- Animal Motifs: Rhinocerous beetles. They're as aggressive as a rhino, and their wings are folded into a beetle-like carapace.
- The Bully: Gembreakers are foul-tempered by nature, form gangs, and pick on any other creature they encounter for the crime of crossing their path. Even members of their own kind aren't safe.
- Gem Tissue: Their distinctive horn appears to be made of crystal.
- Tough Beetles: They have carapaces like a beetle and are not to be messed with.
Glass Caster
Introduced: "Heart of Glass"
A large hyena-like dragon with no wings.
- Expy: It's ability to produce glass is similar to the Sandbuster.
- Mighty Roar: It can unleash a roar that causes the glass structures to vibrate, allowing the Glass Caster to use echolocation to detect the other dragon.
- Lightning Bruiser: It is very fast dragon, despite it being flightless and has a large size. It manage to fight off Webmaster and Thunder.
Sharp Class
Fierce dragons who all utilize sharp metallic body parts on themselves. They are also sharp mentally and usually super agile. General
- Absurdly Sharp Blade: These dragons have sharp appendages used for cutting.
- Absurdly Sharp Claws: If these dragons have an Absurdly Sharp Blade, it's possibly the claws that are sharp.
Timberjack
Introduced: the How to Train Your Dragon movie (mentioned), "Book of Dragons" (described)
A giant Sharp Class dragon, the Timberjack gets its name from its ability to cut down trees with its huge wings.
- Crippling Overspecialization: The Timberjack's wings are made from two sets of limbs (there's a thumb claw on the top and bottom of them). This makes for an impressive wingspan with a dangerously sharp edge but leaves the Timberjack unable to scratch its own back.
- Giant Flyer: Even by dragon standards, Timberjacks dwarf most dragons with their long bodies and gigantic wings.
- Inconvenient Itch: Thanks to lacking arms and legs, Timberjacks are unable to scratch their bodies when they have an itch. Scratching their backs is apparently an easy way to tame a Timberjack.
- Luckily, My Shield Will Protect Me: Timberjack wings can take a lot of punishment, so naturally they use them for defense.
- Mix-and-Match Critters: A case that involves other dragons, Timberjacks look like legless Typhoomerangs with the head of a Monstrous Nightmare.
- Meaningful Name: "Timber" and "Lumberjack."
- Out of Focus: Timberjacks are only given attention in the “The Book of Dragons” short film. They do not appear in any episodes of the tv series and only make cameos in the sequels.
- The Nine Realms does finally get to feature a Timberjack under Buzzsaw’s control.
- Razor Wings: According to the Book of Dragons, Timberjacks cut down trees just by flying into them.
- Tiny-Headed Behemoth: Compared to their wings which make up most of their body, Timberjacks have really small heads.
- Weird Beard: Timberjacks have a few thin tendrils on their chins.
Speed Stinger
Introduced: "Frozen"
A breed of raptor-like, flightless dragons.
- All Animals Are Dogs: The injured adolescent the riders find in "The Next Big Sting" begins acting like a dog once they gain its trust, playfully running around with Fishlegs and affectionately licking Snotlout's face when he carries it.
- Beware My Stinger Tail: Anything they sting gets paralyzed for the better part of a day.
- Decapitated Army: The pack follows an alpha, and will follow it anywhere. The riders exploit this to get them off Berk by capturing the alpha and flying it away from the island.
- Early-Bird Cameo: It is not immediately obvious due to Hiccup not calling out their name, but their first "appearance" is as a drawing in the Dragon Manual in the first film.
- Fragile Speedster: They aren't very big or tall and look frail, but they are very, very fast.
- Instant Sedation: Their poison takes effect instantly.
- Law of Chromatic Superiority: The alpha has a red crest and red stripes.
- Nothing Is Scarier: There is absolute no information on them in their research notes.
- The Paralyzer: Their stingers are essentially the Flightmare's spraying mist on steroids.
- Pint-Sized Powerhouse: Their leader in particular, who breaks free of Hiccup's bola like it was nothing and just yanks Hiccup's shield off his arm with his tail. Their stingers can also work on dragons much bigger than they are.
- Raptor Attack: With their super speed and pack hunting, they act like dragon raptors.
- Red Eyes, Take Warning: They are very dangerous dragons with blood red eyes.
- Super-Speed: To make up for the fact that they can't fly.
- Walk on Water: Some species of Speed Stingers have developed a membrane on their feet so they can run across bodies of water.
- Zerg Rush: They attack in one massive pack, using their stingers to quickly eliminate any threats before making off with any food they can find.
Razorwhip
Introduced: "Have Dragon Will Travel Part I"
A Sharp Class dragon with metallic scales.
- Absurdly Sharp Blade: The tail spikes of one can casually cut through tree trunks and stone.
- Armored Dragons: The dragon has armor-like scales.
- Blow You Away: As revealed in The Nine Realms, Razorwhips have evolved to create and control tornadoes; they can even ignite their tornadoes with a single flame blast.
- Child Eater: The adult males are this, having nearly driven the entire species to extinction.
- Does Not Like Men: Females become violently aggressive towards males of any species during nesting season.
- Extra-ore-dinary: Its scales are made of metal, including its wings, and the tail spikes that it can shoot.
- Expy: It greatly resembles the Kushala Daora, but with a horn instead of a rusty snout.
- I'm a Humanitarian: See Child Eater
- No-Sell: Its tail can slice through dragon-proof metal.
- Poisonous Person: Razorwhips have poisonous tears.
- Prehensile Tail: A Razorwhip snags its prey with its tail, which is strong enough to uproot a tree.
- Spike Shooter: Like the Deadly Nadder, Razorwhips can shoot tail spikes.
- Tail Slap: A long, prehensile, metal tail will most definitely hurt opponents when used as a whip.
- Technicolor Fire: A Razorwhip's fire breath is blue instead of yellow-orange.
- Trademark Favorite Food: According to the Dragon's Eye, Razorwhips live chiefly on sea slugs. Hiccup and the others use this knowledge to locate Windshear.
Grim Gnasher
Introduced: "Searching for Oswald... and Chicken"
The vultures of the dragon world, these pack hunters prey on the aging and ailing dragons that come to Vanaheim. They can fire their thousands of teeth out of their mouths at would-be attackers.
- Decapitated Army: If the Lead Grim Gnasher is captured then it would render the others completely defenseless.
- More Teeth than the Osmond Family: Described as having thousands of teeth, which they can fire at their prey.
- I'm a Humanitarian: Eat sick and injured dragons.
- Scavengers Are Scum: Behave like carrion birds and frequently fly to Vanaheim to target the sick and injured dragons living there.
Stormcutter
Introduced: How to Train Your Dragon 2
A large Sharp Class dragon is introduced in the second movie. Notable for its four wings and owl-like appearance.
- Abnormal Limb Rotation Range: Fitting in with their owlish look, Stomcutters can turn their heads all the way around and more.
- Ambiguous Situation: Valka’s Stormcutter, Cloudjumper, is the only individual of his species seen throughout the films. It is uncertain whether the species is endangered or if they live in areas far from the archipelago.
- Animal Motifs: The shape of its head, its ability to turn its neck 270 degrees, and a crest on its face resembling a beak, all combine into a dragon with an owl motif.
- Giant Flyer: Is 48 feet long, according to the official website
. When in flight, he dwarfs Toothless in body mass and wingspan. - Ring of Fire: A Stormcutter's Breath Weapon is a tornado of fire.
- Vertebrate with Extra Limbs: It's not unusual for a dragon to have six limbs, but it certainly is unusual for the extra limbs to be a second pair of wings. A unique case. Most of the dragons are the iconic "four legs, pair of wings" variety, with a small minority that avert it by having just hindlimbs and wings (Monstrous Nightmares and Deadly Nadders from the first film, for example). Cloudjumper, like all Stormcutters, has a pair of hindlegs and four wings, though these lay flat atop of each other when he's gliding and so can be missed until you watch him flapping.
Raincutter
Introduced: How to Train Your Dragon 2
A Sharp Class dragon that enjoys rainy weather.
- Long Neck: They have long slender necks.
- No-Sell: The fire of the Raincutter is uniquely unhampered by wet conditions such as heavy rain.
- Trademark Favorite Food: Worms and grubs, which it emerges to forage for during storms.
- Weird Beard: They have a few tendrils hanging from the tip of their chin.
Windstriker
Introduced: How to Train Your Dragon 2
A Sharp Class dragon that attacks foes with jets of super-heated air.
- Blow You Away: The Windstriker superheats air within its body before expelling it in powerful jets to scald enemies.
- Living Prop: Most of them stay in the background throughout the sequels and are not very noticeable.
- Long Neck: They have long slender necks.
- Meaningful Name: Windstrikers quite literally strike their enemies with hot air.
- Use Your Head: It is easy to miss, but one Windstriker uses its head to hit one of Drago’s soldiers as his army charges towards the Ice Sanctuary.
Thornridge
Introduced: How to Train Your Dragon 2
A reclusive, but loyal Sharp Class dragon.
- Big Brother Instinct: Normally aloof and shy, but will rise to the occasion to defend its home and friends.
- Clip Its Wings: When one Thornridge tries to save another dragon caught inside a large dragon trap, the machine snaps shut and closes with a part of the Thronridge’s wing poking out.
- Living Prop: Most of them stay in the background throughout the sequels and are not very noticeable.
- Long Neck: They have long slender necks.
- The Quiet One: The Thornridge is unusually reclusive among the normally vain Sharp Class dragons, but can be persuaded to join battles for the sake of their pack.
- The Stoic: The Thornridge is normally content to live in the shadows, striking out when it is called upon and rarely entering the front lines of a battle.
Scuttleclaw
Introduced: How to Train Your Dragon 2
A Sharp Class dragon with a powerful bite and boisterous offspring.
- Brown Note: The evolved Scuttleclaws in The Nine Realms can make a high-pitched whistling sound that can disorientate other dragons.
- Chekhov's Skill: The rebellious nature of the young Scuttleclaws renders them immune to the call of Bewilderbeasts, allowing them to serve as mounts for the Riders after all their dragons were hypnotized by Drago's dark Alpha.
- Ear Fins: The evolved Scuttleclaw seen in The Nine Realms has fins on the side of its head that could be ears.
- Fearless Infant: The young Scuttleclaws seen are entirely carefree, making the Alpha Bewilderbeast's FACE into their own personal playground. Averted in the third movie where one is visibly nervous around Grimmel’s Deathgrippers.
- No Sense of Personal Space: The Scuttleclaw hatchlings love to play around Toothless, even though it is clear he does not tolerate their presence.
- Not Allowed to Grow Up: Infant Scuttleclaws are the only kind of Scuttleclaws seen in the movies.
- Out of Focus: We never see any adult Scuttleclaws.
- Puppy-Dog Eyes: All young Scuttleclaws have these eyes.
- Reused Character Design: Their adult forms are only scene in the app games and look like Nadders without the spiky features and Zippleback-like spines.
- Ridiculously Cute Critter: The young are absolutely adorable.
- Stronger Than They Look: They aren’t much bigger than a human, yet they are strong enough to carry Vikings like Gobber and Fishlegs on their backs.
Bubblehorn
Introduced: "Uniconned"
A small dragon with the ability to blow an exploding bubble out of its horn.
- Bubble Gun: Its explosive bubbles move as slow as expected, but it can create dozens, and those bubbles can merge into a bigger bubble.
- Cute Is Evil: As adorable as it is, it's also a relentless scavenger that will tear rooms apart to get food, and quickly turn off people that take exception to this. The Bubblehorn gang tries blowing up all of I.C.A.R.I.S. out of spite when the Dragon Club succeeds in driving them away.
- Deliberately Cute Child: Humans and dragons will mistake it for a helpless hatchling, and try protecting it from others. This proves to be a mistake, as it eats all the food it can find, refuses to share, destroys things when it doesn't get its way, and calls in reinforcements when its victims get sick of it.
- Non-Standard Character Design: They look way more overly cutesy and simplified compared to the other dragons in the franchise. This makes sense considering their designs are reused from dragons created for a preschool spin-off.
- Reused Character Design: The Bubblehorn has the same design as the Relentless Rainbowhorn from Rescue Riders'.
- Spikes of Villainy: When in combat mode, they'll grow more spikes to look intimidating.
- Zerg Rush: Once a Bubblehorn finds food, or itself in trouble, it will scream and alert its whole pack, who will come to investigate.
Woodchipper
Introduced: "Hearts of Heroes"
A group of small dragons with a stocky build and stubby legs.
Tidal Class
Dragons who all dwell in water, both fresh and salt. Contains some of the biggest dragons in existence. General
- The Big Guy: Most dragons are huge already, but these sea-dwelling dragons are truly titanic.
- Fantastic Fauna Counterpart: Tidal Class Dragons are clearly this world's analogue of whales, cetaceans, amphibians, and mosasaurs.
- Flying Seafood Special: Some of these dragons are just as good at swimming as they are flying.
- Making a Splash: Tidal Class Dragons use water-based attacks on their enemies.
- Sea Monster: More like "Sea Dragon". But their bizarre appearance and ocean-living behavior makes them appear as sea monsters.
- Shown Their Work: Since almost all Tidal Class Dragon are much larger than their land and sky counterparts, it is clear that all these dragons have followed an evolutionary trend called "deep-sea gigantism" in which animals adapted to spend their lives in the sea can reach massive sizes.
Thunderdrum
Introduced: "How To Pick Your Dragon".
One of the original two Tidal Class dragons known in the series, Thunderdrums are large, frog-like dragons who spend most of their time in the water.
- Crippling Overspecialization: As seen in “Imperfect Harmony”, the Thunderdrums short legs makes them slow when they run on land and in combat they are unable to fight back properly when they are pinned down.
- Disability Immunity: Thunderdrums' being hard of hearing makes them immune to the Death Song's spell. However, the Screaming Death’s scream is loud enough to stagger Thornado, as shown in “Tunnel Vision”. Keep in mind that Thunderdrums are hard of hearing, and nearly deaf, when out of water.
- Early-Bird Cameo: Its first "appearance" is as a drawing in the Dragon Manual in the film. It isn't properly introduced until the show.
- Flying Seafood Special: Its introduction has it switching from swimming expertly underwater to a flying Lightning Bruiser. The Other Wiki confirms that it is at least semi-amphibious to survive on dry land.
- Gale-Force Sound: It produces a roar that is so load and powerful, it can sends its opponents flying backwards.
- Lightning Bruiser: Is fast enough to dodge Toothless' fast-firing plasma shots, and strong enough to plow through solid rock without a scratch, or tow large ships single-handedly.
- More Teeth than the Osmond Family: Its mouth is all fangs and its head is wide enough to hold Stoick the Vast comfortably.
- Prehensile Tail: It uses its tail to grab Stoick and drag him under without leaving the water itself.
- Required Secondary Powers: Hiccup speculates that they're deaf to an extent, (At least to their own sonic vibrations, given that tame ones can understand their riders). Additionally, they're immune to other dragon species', (such as the Death Song siren song), sound-sound-based abilities, or hypnosis.
- Sea Monster: According to The Other Wiki, Thunderdrums are capable of growing too, or exceeding the size of a Blue Whale. This is shown to be true in How to Train Your Dragon 2 when Hiccup and Toothless fly past a pod of gigantic Thunderdrums, with one individual being big enough for Toothless to fly under its entire wing.
- Super-Scream: It has a sonic scream, though its ability to scream someone's head clean off (as Hiccup narrated in the film) seems to have been an exaggeration, or not shown due to violence restrictions. It can, however, shatter reinforced wood and rock. This makes it one of the two dragons confirmed as not having fire-based breath weapons.
- Thunder Drum: Related to this trope In Name Only - its sonic scream resembles rolling thunder but has nothing to do with drumming.
Scauldron
Introduced: "Dragon Flower"
A large Tidal Class dragon that lives almost entirely out to sea. Spends most of its time underwater and so is rarely a threat unless it takes a hankering for a netload of fish, or decides to get territorial around a ship. It drinks in gallons of seawater, boils it in its stomach, and sprays it out like a firehose to scald its enemy.
- Balloon Belly: When Scauldrons swallow lots of and lots of water, their stomachs can rapidly expand while the water boils inside it.
- The Cameo: One Scauldron can be seen amongst Berk’s dragons in the third movie sitting half-submerged in a water tower.
- Early-Bird Cameo: Its first "appearance" is as a drawing in the Dragon Manual in the film. It isn't properly introduced until the show.
- Flying Seafood Special: It is implied in Book of Dragons and shown in Race to the Edge that Scauldrons can fly too, despite being an aquatic dragon.
- Hair-Trigger Temper: Scauldrons are very aggressive and will attack anyone in an instance.
- I'm a Humanitarian: Preys on the Seashocker. One would also have been willing to eat Fishleg’s Gronckle, Meatlug.
- Long Neck: They have very long necks that they can use to poke their head above the water while the rest of their body is submerged.
- Making a Splash: As an aquatic dragon, its Breath Weapon is based on swallowing liters of water and heating them to boiling inside its belly, allowing it to spray targets with powerful geysers of searing water. As with the Thunderdrum above, the book embellishes this ability; the water may be hot, but it's certainly not as dangerous as the book would have one belief, given how easily the attack is blocked.
- No-Sell: Can eat the blue oleander, a flower that is deadly poisonous to all other dragons.
- Poisonous Person: If it eats the right kind of flowers (which are deadly to other dragons), it becomes one of these. This also makes its venom a good cure for the poison in the flowers.
- Sea Monster: Gobber mentions they can grow over 60 feet long, but the individuals the Dragon Riders come across are show to grow much bigger than a ship. They also happen to be very hostile beasts.
Seashocker
Introduced: How to Train Your Dragon 2
A manta ray-like Tidal Class dragon with two heads and electrical abilities.
- Advertised Extra: Despite getting a promotional render and being one of the many new species hyped for the 2nd movie, Seashockers only appear two times in the entire movie and aren’t particularly focused on. At least there would be an entire episode focusing on a stranded individual later down the line.
- Bioluminescence Is Cool: The light from their electricity aside, Seashockers can glow in the dark, a useful ability when one can dive into the deep ocean. Some can be seen glowing a bright blue in some pools within the Hidden World.
- Cold-Blooded Whatever: The HTTYD website described Seashockers as being related to electric eels, even though dragons are reptiles and eels are fish.
- Graceful in Their Element: Unlike some Tidal Class dragons, Seashockers are not capable of flying in the air and are mostly found under the sea.
- Jagged Mouth: Their upper jaws are serrated.
- Limit Break: Joining the two heads causes a Seashocker to release its electricity in an electromagnetic pulse, allowing for an attack with a large spherical range. Said attack is stronger underwater than in the air, but either way, the Seashocker requires a cooldown period afterward.
- Mysterious Animal Senses: Living underwater, they benefit from using echolocation to catch prey.
- Razor Wings: Some are seen cutting through sea ice with their dorsal fins.
- Shark Fin of Doom: Subverted; When their fins poke above the water and the ice as Toothless struggles to stay afloat, they drag him beneath the water to take him elsewhere. However, they apparently bring him over to another one of Valka’s dragons, who carries him to the Dragon Sanctuary to reunite with Hiccup.
- Shock and Awe: It's in the name, and this ability gets stronger if they join their heads.
- Zerg Rush: They hunt in pods, much like orcas.
Submaripper
Introduced: "Dire Straits"
A giant, frog-like Tidal Class dragon that is known for creating whirlpools strong enough to drown entire Viking ships.
- Arch-Enemy: Submarippers and Shellfires are natural enemies, and attack each other on sight.
- Blow You Away: It can make whirlwinds in addition to whirlpools, meaning flyers aren't safe from it either.
- Gasshole: A Submarripper's presence is heralded by the foul stench of its breath.
- I'm a Humanitarian: Humans and dragons alike aren't safe from the Submaripper's jaws. That being said, it is noted that they're not known for attacking humans and usually live in very deep water, far from people. Albeit the attacks are indicated to be more about it being territorial and defensive rather than hungry.
- Making a Splash: It can inhale hard enough to create whirlpools and tidal waves, making it a destructive force all on its own.
- Mega Maelstrom: The whirlpools created by a Submaripper are stronger than any natural whirlpool, to the point of being able to suck down dragons that aren't even touching the water.
- Retcon: The Submaripper seen in the comics and mobile games was a different-looking and behaving dragon, though whirlpools were still associated with it. When RTTE depicted this new one, that dragon was renamed the Ripwrecker, which was its name in some localizations.
- Vacuum Mouth: It sucks its prey into its mouth through water and air.
Shellfire
Introduced: "Shell Shocked"
A giant, armored Tidal Class dragon with a blue, meteor-like Breath Weapon.
- Arch-Enemy: Shellfires and Submarippers are natural enemies, and attack each other on sight.
- Armored Dragons: Unlike the Boneknapper and Armorwing, the Shellfire's armor plating is natural.
- Dishing Out Dirt/Magma Man: Its Breath Weapon is an explosive half-melted boulder, with the lava part being blue.
- Long-Range Fighter: It can launch its explosive boulders over a mile. Not that being close to it is any safer.
- Suspiciously Similar Substitute: A large Tidal Class dragon enslaved by dragon hunters and used as the ace up their sleeve to attack the heroes. The Shellfire even has horns similar to the tusks of a Bewilderbeast.
- Technicolor Fire: The Shellfire's boulder blasts are blue and explode like fireworks.
- Turtle Island: Given how big they are, it's only natural for Vikings to have mistaken Shellfires for islands in the past, complete with wrecking their ships on them.
Bewilderbeast
Introduced: How to Train Your Dragon 2
Described as the alpha species, Bewilderbeasts are titanic Tidal Class dragons that naturally tend to find the role of alpha dragon amongst packs.
- An Ice Person: In a world filled with fire-breathing dragons, Bewilderbeasts deserve special notice for having ice breath. They are even capable of using these to form massive nests.
- Animal Motifs: Has some leonine characteristics, including a certain majesty and a large "mane" of head spikes. Their tusks and large size in comparison to other dragons also make them resemble elephants.
- Bizarrchitecture: Bewilderbeasts make these for a living, fashioning near-impenetrable nests out of their ice breath. You wouldn't guess that if you were outside.
- Cool Crown: Their spines give the allusion to this.
- Gigantic Adults, Tiny Babies: The Bewilderbeast egg Hiccup finds is the size of a typical dragon egg, i.e. the size of a football. The adult Bewilderbeasts are 500 feet long— 500 times the length of the said egg.
- The High King: See the below quote.Valka: Every nest has its queen, but this is the king of all dragons!
- Icy Blue Eyes: Their natural eye color is light blue. Drago's one appears to have bloodshot red eyes, which is a sign of its abuse.
- Kaiju: Bewilderbeasts are nothing short of titanic. They're 160 feet tall according to the official website.
- Lightning Bruiser: A fully-grown Bewilderbeast swims at incredible speeds according to the ''How To Train Your Dragon'' website.
- Royals Who Actually Do Something: The official website states that Bewilderbeasts are not born into alpha status; it is earned through combat, vigilance, and most importantly, a desire to protect the dragons in its nest. It helps that their massive strength and power make the task relatively easy for them, but they still earn it.
- Weird Beard: They have several spines covering their chins that look similar to a beard.
- Wings Do Nothing: Downplayed; Although Bewilderbeasts have short stiff wings that would make them unable to fly, their wings actually help them swim at great speeds.
Mist Twister
Introduced: "A Hole New World"
A two-headed eastern dragon that breathes fire from one head, and ice from the other.
- Big Ol' Eyebrows: Both heads posess thick eyebrows.
- Blue Is Calm: The blue head is more composed than the red head.
- Fiery Redhead: An almost literal example. The red head is the head that breathes fire and has more of a temper.
- Fire/Ice Duo: A single being with two heads that use fire and ice, and the personalities to match.
- Multiple Head Case: In this case, the red head has a more firey personality, and the blue head is more cool-headed. Naturally, they breathe the corresponding element.
- Yin-Yang Bomb: Their ice-and-firepower is formidable on its own, but creates more useful effects if used in tandem.
Flood Fang
Introduced: "Downpour"
A large, aquatic dragon resembling a mix of a basking shark and a manta ray.
- Animal Motifs: Floodfangs are comparable to baleen whales because they are both gargantuan sea-dwelling creatures who exclusively eat mouthfuls of tiny animals.
- Delicious Distraction: Its favorite prey, which is fireflies, is small, yet tasty enough that it will follow a bag of them for miles out of its habitat.
- Flying Seafood Special: Like the Thunderdrums, the Flood Fangs can fly out of the water and have an amphibious nature to survive on dry land.
- If It Swims, It Flies: Despite having wings like Seashockers, sea dragons incapable of flight, Floodfangs can fly pretty effortlessly.
- Making a Splash: It can store enough water in its mouth to resemble a sudden downpour when it opens.
Octofin
Introduced: "In Too Deep"
A wingless, crocodile-like aquatic dragon with eight tails.
- Multiple-Tailed Beast: It has eight tails, each one of them as prehensile as an octopus tentacle.
Mystery Class
Enigmatic and highly varied dragons who exhibit incredibly unusual and unorthodox abilities, some almost supernatural in nature. General
- The Dreaded: Most of the Mystery Class Dragons are former Fear Class Dragons. A.K.A. the most feared dragons. Due to their habit of ambushing their prey.
- Non-Standard Character Design: Mystery Class Dragons have very strange anatomies.
- Nothing Is Scarier: We know very little about these bizarre dragons. Which makes them all the more terrifying.
- Stealth Expert: Most of these dragons are very good at remaining hidden in their own unique ways.
Hideous Zippleback
Introduced: the How to Train Your Dragon movie.
The Hideous Zippleback was originally the iconic Fear Class dragon but was reclassified when the Vikings of Berk no longer need to fear dragons. This two-headed dragon exemplifies the bizarre nature of its class with its two heads which must work in tandem to be dangerous. One head breathes the gas, and the other lights it, resulting in major explosions. The gas itself is also dangerous, but only with long-term exposure.
- I Owe You My Life: They understand the concept of a life debt and will gratefully follow anyone that saves their lives.
- Knockout Gas: The gas emitted by the right head can be this; after all, breathing flammable gas is never a good thing.
- Long Neck: Both heads are connected to really long necks that can “zip” together when in flight.
- Multiple Head Case: Inverted in that the two heads work together quite well, with one providing flammable gas, and the other a pilot light.
- Multiple-Tailed Beast: Two heads means two tails.
- Organ Autonomy: The two heads of a Hideous Zippleback are distinct and do not share each other's thoughts. If the heads start arguing, the dragon can stall out, leaving it vulnerable to attack.
- Rolling Attack: Zipplebacks can turn into a flaming wheel by releasing a large amount of gas before biting onto their tails and setting themselves alight, knocking and burning everything in their path.
- Stuff Blowing Up: Zipplebacks can create explosions when one head breathes gas and the other head generates sparks that ignite it.
- Super-Strength: Zipplebacks have incredible strength that matches a Night Fury and a Monstrous Nightmare. In fact, Barf and Belch were able to use their neck strength to break Gronckle Iron metal (which Fishlegs thought to be dragon proof).
- Weaksauce Weakness: Throw a bucket of water onto the head that sparks the gas and it is unable to light its gas. That said, finding the right head is the trick.
- Underestimating Badassery: Zipplebacks are stated to be poor fliers and walkers but they showed repeatedly that they are quite flexible, agile, and fast. Also despite their large size and relatively short but broad wings, Zipplebacks are overall the second or third fastest dragons in flight.
Boneknapper
Introduced: "Legend of the Boneknapper Dragon"
A large Mystery Class dragon, Boneknappers earn their moniker due to their macabre habit of assembling an armor of dragon bones to shield their bodies.
- Arch-Enemy: To Gobber, until it's revealed why.
- Armored Dragons: Armor made from bones.
- Bad with the Bone: A cluster of bones at its tail similar to an Ankylosaurus club implies some sort of combat use.
- Collector of the Strange: It collects the bones of other dragons and wears them like armor.
- Determinator: The Boneknapper that was Gobber's rival in the short. Its lifelong feud with Gobber has lasted for what can only be described as decades two. Even after being attacked by a Hammerheaded Whale and Yak being sent by Thor, not only did the dragon survive, but it continued to hunt.
- Elemental Armor: The dragon bones it covers its body with qualify as this.
- Gale-Force Sound: Gains this ability once it has every bone it needs, though it's not as strong as Thunderdrum's Super-Scream.
- Heel–Face Turn: Once a Boneknapper gets all its bones, they become incredibly docile. Best described by Gobber:Gobber: You give a Boneknapper whatever it's looking for and it's just like an overgrown puppy dog.
- Scary Impractical Armor: Zigzagged with the Boneknapper's shell of dragon bones, which seems to be quite practical and is intended mostly to be scary.
- Skeletons in the Coat Closet: It scavenges the bones of dead dragons to create a coat of armor that can protect its soft hide.
- The Voiceless: Unless it has every bone it needs for its armor, the Boneknapper can't roar.
Snaptrapper
Introduced: the How to Train Your Dragon movie (mentioned), "Book of Dragons" (described)
A four-headed Mystery Class dragon, Snaptrappers are often compared to Venus Flytraps due to their ability to lure prey into their flower-like jaws with a sweet scent.
- Flower Motifs: When a Snaptrapper's triple jaws are wide open, it looks like a blooming flower, and might even smell like one. However, comparing it to a Venus Flytrap is more accurate.
- Flower Mouth: They have three separate jaws that can open up like a blooming flower.
- Happy Rain: The "Book of Dragons" short mentions how these dragons love rainy weather.
- Multiple-Tailed Beast: Snaptrappers have a forked tail, like the Zippleback.
- Organ Autonomy: Given the Zippleback, it's likely that Snaptrappers have this problem times two.
- Out of Focus: So far, there hasn't been much material covering Snaptrappers since the "Book of Dragons" short. Other appearances it has across the franchise amount to a cameo on one of Fishleg’s dragon cards in the second movie and some appearances in the video games and comics.
- Poisonous Person: Snaptrappers have the most deadly venom of any dragon.
- Signature Scent: According to the Book of Dragons, the Snaptrapper can imitate the smell of chocolate. Odd, given that the Vikings didn't have chocolate.
- Stealth Expert: At first glance, a Snaptrapper would look like a weird plant. This is due to its ability to hold still long enough for prey to fall into its reach.
Smothering Smokebreath
Introduced: "Breakneck Bog"
Small Mystery Class dragons that dwell in isolated regions. They produce thick clouds of smoke and use this as camouflage.
- The Collector: They collect any metal items encountered, which they then meld together to build their nests. Justified, as they're rather small in size and use those nests to protect themselves from attacks by larger dragons.
- Dragon Hoard: Building a nest of metal is clearly intended as a play on this tradition, although it's mostly not precious metal (they were very interested in Snotlout's gold chain, though, because it was shiny).
- Greed: All the Smokebreaths seen so far will stop at nothing to get any metal they see, much to the ire of humans and Armorwings.
- Jagged Mouth: They are fierce dragons with little serrations on their mouths.
- The Napoleon: Third shortest breed of dragons seen so far, they're also fiercely territorial and very aggressive. Hiccup and the others didn't even try to train these things!
- Smoke Shield: Invoked. They make a foggy-like smoke to act as protection, combined with metal scraps, to appear larger and scare others off.
- Pintsized Powerhouse: Surprisingly strong for little dragons too.
- Shoulder-Sized Dragon: Smothering Smokebreaths are about the same size as Terrible Terrors.
- Zerg Rush: They attack swiftly and in great numbers to overwhelm (or at least scare off) their victims.
Changewing
Introduced: "Gem of a Different Color"
A member of the Mystery Class of dragons, Changewings are best known for their chameleonic scales, which make them extremely difficult to find.
- Constantly Curious: Stated to be their natural personality trait in Book of Dragons.
- Early-Bird Cameo: Its first "appearance" is as a drawing in the Dragon Manual in the film. It isn't properly introduced until the show.
- Face–Heel Turn: After the Outcasts tame and weaponize the local Changewing population. They're animals, so they're not inherently evil, but they're certainly being used for evil ends.
- Fiery Redhead: Although they don't have hair, Changewings have a hair-like braid and have red skin (although some have green).
- Hollywood Acid: Not as strong as in many examples of the trope (it can damage stone but can't go through it and it barely scratches metal bars) but the speed at which it melts wood is still uncanny.
- Hypnotic Eyes: Demonstrated in Book of Dragons that it possesses this ability, though it hasn't used it yet in the series. It was used in a Dragons: Riders of Berk tie-in comic.
- I'm a Humanitarian: Preys on other dragons like the Night Terrors and Scauldrons.
- Invisibility: Can flawlessly blend in with their surroundings. However, in open skies, they are unable to camouflage.
- Mama Bear: Stealing their eggs is not a good idea. In fact, if multiple eggs are taken, ALL the mother dragons will work together to retrieve them, and they won't leave until they have them ALL back.
- No-Sell: Not only is their acid non-soluble in water, but underwater, it can dissolve "dragon-proof" metal.
- Squishy Wizard: For a dragon, anyway. Gobber mentions in the Book of Dragons that their scales are softer as a side effect of their concealment, making them more vulnerable to attack once found.
Flightmare
Introduced: "Fright of Passage"
The Flightmare is a Mystery Class (originally from the Fear Class) dragon that appears in Dragons: Defenders of Berk. It is among the most terrifying and frightening dragons.
- Arch-Enemy: To Astrid and her family.
- Bioluminescence Is Cool: Its diet of glowing algae causes its entire body to glow with bright blue light. This extends to other dragons that eat the algae, but the effect would seem to be permanent (or at the very least quite long-lasting) for the Flightmare.
- Blinded by the Light: The Flightmare uses this as one of its abilities. As with its general bioluminescence, other dragons can copy the effect.
- The Dreaded: It was one of the most feared dragon species in the Barbaric Archipelago before the Dragon Riders discovered its true natural behavior.
- Fear Is the Appropriate Response: Lampshaded by everyone in Berk.
- Light Is Not Good: The Flightmare glows bright blue and attacks anything it feels is a threat to its food supply.
- Nightmare Face: It looks more like a ghostly deep-sea creature than a dragon.
- The Paralyzer: It sprays a mist that causes its victims to freeze up for about a minute, allowing it to eat them with impunity. As most people don't survive this effect, the villagers attributed it to the victims choking in fear at the last moment, a fact which shamed Astrid's family when her "fearless" uncle fell prey to it.
- Super Spit: Its Breath Weapon. See The Paralyzer above.
Death Song
Introduced: "Imperfect Harmony"
One of the first new species of dragons the group encounters on their travels. The Death Song gains its name from its ability to lure prey with an enthralling screech.
- Animal Motifs: Clearly designed to resemble a butterfly, but it also cocoons its prey as a spider would.
- Beauty Is Bad: They are one of the most eye-catching species of dragons with their beautiful colors, yet they prey on just about any dragon that wanders into their domain.
- Big Eater: Judging by the piles and piles of dragon bones near its territory, the Death Song has a voracious appetite. It is even shown taking away dragons stuck in its amber to eat them and quickly coming back for more.
- Compelling Voice: Lures dragons in with it screeches, traps them in an amber-like substance, and then moves in for the kill at its leisure.
- Hoist by His Own Petard: The Death Song's trapping substance can only be dissolved with the heat of its fire breath. So Hiccup jury rigs things so it attacking will free the riders and their dragons.
- I'm a Humanitarian: It eats the dragons it captures. It also was willing to eat their riders too.
- Luring in Prey: Uses its enticing call to lure dragons into coming into its territory.
- Music Soothes the Savage Beast: Death Songs communicate via melody, so Garff is less troublesome when the riders try singing to him. The adult Death Song, on the other hand, doesn't like how they sing.
- Names to Run Away from Really Fast: This dragon is a flat-out equal opportunity predator. There is no room to take chances with one.
- No-Sell: Their hardened amber can serve as a shield against Slitherwing poison.
- Siren Song: Its screeching sounds like a haunting melody from afar, and it hypnotizes other dragons into getting close enough to be eaten by it.
- Tail Slap: The Death Song's unusually long tail is strong enough to knock a Thunderdrum onto its back.
Armorwing
Introduced: "Snotlout Gets The Axe"
A Mystery Class dragon that lacks natural armor, but steals metal objects to create a metal armoring to protect its body.
- Armored Dragons: It's a dragon that makes its own armor out of scavenged metal.
- The Collector: Like the Smokebreaths, it collects metal. Like the Boneknapper, its collection is made into armor.
- Desperation Attack: The Armorwing can set parts of its armor ablaze before flinging them at intended targets. This ability, however, will gradually expose its scaleless body and makes it more vulnerable to its enemies.
- Dragon Hoard: It collects any metals it can find and hides them away in case it needs to replace any pieces of its armor.
- Eye Scream: Armorwings have an incredibly bright flame, and blast other dragons in the face to blind them.
- Reused Character Design: They look like thinner Boneknappers in terms of body proportions.
- Selective Magnetism: This dragon is somewhat magnetic, as it needs to affix scraps of metal onto its body somehow. It's too weak of an attraction to be considered Magnetism Manipulation.
- Underground Monkey: They strongly resemble Boneknappers in appearance and behavior. For instance, both species collect specific materials to build a suit of armor out of to protect their soft skin.
Cavern Crasher
Introduced: "Crash Course"
A large salamander-like dragon that forces other dragons out of their caves and takes over.
- Breath Weapon: A less powerful variant than most dragons, because it serves more to activate its flammable slime than as a weapon of its own.
- Child Eater: Eats the eggs and babies of other dragons.
- Evil Egg Eater: Eats the eggs (and hatchlings) of other dragon species, which unsurprisingly puts it at odds with the Hooligans and their dragons.
- Fast Tunnelling: Helped along by its collapsible skeleton and slimy coating, allowing it to slip through smaller openings.
- Fiery Salamander: It looks a lot like a salamander and breathes green blasts of fire. It also secretes flammable slime.
- I'm a Humanitarian: See Child Eater
- Incendiary Exponent: It secretes flammable slime and flings it at its opponents.
- Lightning Bruiser: Moves much faster than something its size should.
- Made of Iron: Shrugs off every attack the dragons throw at it, including plasma blasts and massive boulders.
- Technicolor Fire: The flames it breathes out are green.
- Wall Crawl: It can stick to walls like a gecko, giving it a major advantage in caves.
Buffalord
Introduced: "Buffalord Soldier"
A yak-like dragon that was hunted to near extinction because its saliva could cure the Scourge of Odin.
- Berserk Button: Usually docile, but take it away from its food source and a Buffalord will show its displeasure by inflating, followed by flames and spines.
- Endangered Species: An in-universe example. These dragons have been hunted for their saliva to near extinction. Only one individual is ever seen in the flesh. The ambiguously canon video games Rise of Berk and School of Dragons shows there are other Buffalords though.
- Fantastic Medicinal Bodily Product: It has medicinal saliva which is the only known cure for the disease known as the Scourge of Odin. However, this is only after it chews a special type of grass.
- Gentle Giant: A dragon of imposing size, but gentle in nature. Until you move it from its island.
- Herbivores Are Friendly: They are some of the few primarily herbivorous dragons and are extremely passive.
- Implacable Dragon: An inverted example; rather than stopping at nothing to get something, it will stop at nothing to stay where it is. It smashes through dragon-proof cages and ship decks with ease to get back.
- Spike Shooter: When a Buffalord puffs up like a pufferfish, that means it's going to shoot the spines on its body.
Sandbuster
Introduced: "Sandbusted"
An aggressive dragon that attacks Vikings with shiny objects and drags them beneath the sand to its underground lair. Fortunately, it can be harmed by direct sunlight.
- Antlion Monster: Humans that walk through sand patches it hunts in are immediately dragged under.
- Dragon Hoard: It collects any items from its victims and becomes protective over them.
- Pinball Projectile: Its glass shots bounce off surfaces.
- Prehensile Tail: It can coil its tail around humans like a python and drag them underground.
- Sand Worm: See Tunnel King
- Tunnel King: It can burrow through sand like a fish through water.
- Weakened by the Light: Lives underground because sunlight instantly burns its skin.
Slitherwing
Introduced: "No Dragon Left Behind"
Dragons that resemble giant snakes with wings with the ability to spit and secrete an extremely deadly poison.
- Animal Motifs: Snakes. Their red, black, and yellow coloring is reminiscent of coral snakes, and they have the ability to spew poison like a spitting cobra.
- Artistic License – Biology: As mentioned above, they're poisonous snake-like dragons that have a red, black, and yellow pattern. The problem though is that the red is touching the black as opposed to the yellow, thus making them look like some North American milk snakes, a non-poisonous species. Subverted in that this color pattern is found in some venomous coral snakes in South America and such.
- No-Sell: Their poison-coated scales cause Death Song amber to slip off before it can harden.
- Poisonous Person: Not only do they have a venomous bite, but they're also coated in poison. Merely touching one will kill the victim by the next moon.
- Red and Black and Evil All Over: Slitherwings have these bold colors and are extremely hostile.
- Snakes Are Sinister: They're snake-like dragons that attack on sight.
Dramillion
Introduced: "Loyal Order Of Ingerman"
A Mystery Class dragon with the mysterious ability to replicate the Breath Weapon of any dragon species they see.
- Endangered Species: They have been hunted to near extinction by the Ingerman family. The last remaining individuals are secluded to a single island.
- Invisibility: Being related to Changewings, Dramillions can also flawlessly camouflage themselves (though it seems only their Titan Wing variant can do this).
- Large and in Charge: The Titan Wing Dramillion is much larger than the other Dramillions and seems to act as their leader.
- No-Sell: Having both lava and concussive fire blasts, they're able to destroy "dragon-proof" metal on their own (they can weaken the metal with lava and shatter it with a magnesium blast, something no other dragon species could do). Albeit they had to be shown how to do this before they could make use of combining their breath attacks. However, one Dramillion cannot combine the blast together by itself so they each have to do one at a time.
- Not So Extinct: After learning his ancestors practically wiped most of the Dramillion population out in "Loyal Order Of Ingerman", Fishlegs is relieved to find a small island with a pack of these dragons.
- Power Copying: Able to mimic the fires of other dragons they encounter.
Silkspanner
Introduced: ''How To Train Your Dragon Burning Midnight "
Spider-like dragons spit a strong silk.

- No-Sell: The Silkspanners are immune to Dragonvine, a plant that is poisonous to humans and deadly to dragons.
- Not Quite Flight: They can use the silk webs in between their three pairs of legs to glide great distances. This makes up for their lack of wings.
- Projectile Webbing: Silkspanners shoot flaming silk webs.
- Spider Limbs: They have six legs like a spider.
- Wall Crawl: It is expected for spider-like dragons.
- Zerg Rush: Silkspanners hunt in packs to bring down large prey.

Introduced: How To Train Your Dragon: The Serpent's Heir
A colossal Mystery Class dragon that grows tree-like spines and can hibernate for decades.

- Giant Flyer: Just like the Red Death, they are capable of flight despite their immense size.
- Long-Lived: Considering how long these dragons can take their naps, they must live for many many years.
- Walking Spoiler: Talking about their presence in The Serpent’s Heir would reveal the fact the island Nepenthe was made up of six Foreverwings who have been asleep for generations.
- Weird Beard: They have long stringy beards shaped like tree roots.
Hobgobbler
Introduced: How to Train Your Dragon: The Hidden World
A small and round frog-like Mystery Class dragon.
- Explosive Breeder: The Dragon Riders only brought one Hobgobbler to Berk from their latest rescue mission. When they settle on New Berk, there are dozens or even hundreds of these chubby critters.
- Extreme Omnivore: When Gobber unleashes a tide of Hobgobblers on an opponent during the final battle, the swarm of razor-toothed little dragons ends up stripping the planks off the deck.
- Fly in the Soup: Gobber is startled to see one Hobgobbler swimming in a large cauldron of soup. Toothless stares it down to make it come out.
- Hellish Pupils: A unique variant when compared to other dragons; Hobgobblers have horizontal pupils like a goat.
- The Jinx: Gobber believes they are a bad omen.
- Killer Rabbit: Gobber comments on how these plump yet ravenous dragons can breed faster than rabbits.
- Mix-and-Match Critters: The Hobgobbler is described to be a mix of a bullfrog, a French bulldog, and a beachball, with the fearsome appetite of a piranha.
- No-Neck Chump: Hobgobblers have no room for necks on their round little bodies.
- Offscreen Telaportation: They have a habit of showing up in random places when no one is looking. Gobber is especially creeped out by this.

A shy dragon with a crest that resembles a set of feathers.
- Chameleon Camouflage: It can turn completely invisible, though with occasional Visible Invisibility for the viewer's sake.
- Disability Immunity: Featherhides are immune to the high-pitched screams of modern-day evolved Scuttleclaws.

- Spider Limbs: They have eight legs like a spider.
- Suspiciously Similar Substitute: For the Silkspanners of the comics, being spider-like dragons that can catch larger prey in their webs.

Jörmungandr
Introduced: "Rise of Jörmungandr"
The Apex Predator of all dragons
- Snakes Are Sinister: Like the Slitherwings, Jörmungandr has a snake-like body. D'Angelo believes the Jörmungandr could also be the reason dragons fear serpent-like creatures, due to its status as the apex predator of all dragon kind. Unaware that eels are very poisonous to most species of dragons and can cause the disease Eel Pox if ingested by a dragon.
Other
Lycanwing
Introduced: "Bad Moon Rising"
Dragon Class: N/A
Dragon Class: N/A
A mythical dragon that allegedly bites humans to turn them into fellow members of its species.
- Animal Motifs: Clearly takes inspiration from werewolves, and wolves by proxy.
- The Dreaded: Upon hearing that he might have been bitten by one, Tuffnut freaks out badly.
- Meaningful Name: "Lycanwing", as in lycanthropy or being a werewolf.
- Our Werebeasts Are Different: They're practically weredragons.
- Real After All: Subverted. While Hiccup begins to panic after thinking that it may be real, he and Fishlegs discover that Tuffnut was bitten by a wolf. The so-called Lycanwing was just made up to scare away marauders. To date, of the three mythical dragons mentioned in the continuity, it is the only one with no actual proof of its existence.
- Shout-Out: To werewolves in general.
- Shrouded in Myth: As can be expected from something based on a werewolf.
