Viking Era
The Red Death
Appearances: How to Train Your Dragon
A massive dragon who ruled the nest of the dragons raiding the Hooligan village. It forces them to bring it food, and if any them fail to bring enough to satisfy it, it eats them.
- Adaptation Name Change: In the books, it is known as the Green Death. In the movie, it was a case of No Name Given; as such, this section was previously listed under the dragon's literary name. It was changed after the dragon was referred to as the Red Death in a couple of the animated series' episodes.
- Ambiguous Gender: It's referred to as male in the movie, but also called a "Queen", and referred to as female sometimes out of the movie. Its counterpart in the books was male. In general, fans mostly consider this one to be female.
- Bad Boss: It forces the other dragons to deliver food; if they don't, or fail to bring it enough, it will eat them instead.
- Big Bad: It's the one forcing the other dragons to hunt for it, which drives them to attack the Hooligan village. The rest of the dragons being able to co-exist with them in the second movie implies it eats more than all of them combined.
- Big Eater: Given its size that's inevitable. Since it decided getting food for itself was too much trouble, it had the other dragons in the first film get food for it, and from what seen of its raids, it eats enough food to feed entire communities.
- Breath Weapon: Like all dragons its got one, but its breath weapon is one based on making pyroclastic clouds. Nothing near it stands much of a chance, until our heroes get into the fight.
- Continuity Cameo: One of Fishleg’s dragon cards in the second movie has a Red Death on it. In the third movie, a drawing of the Red Death can also be seen on Hiccup’s map.
- Cruel and Unusual Death: After Hiccup and Toothless lure the Red Death high into the sky, they torch holes through its wings and set it on fire from the inside before baiting it into a powerdive after them: only pulling up right at the last moment. Unable to stop due to both its gargantuan mass and moving Too Fast to Stop, it plows head-first into the ground and kills itself: its head exploding in flames on impact.
- Dragons Are Demonic: It is a horrifying force of nature that is treated as the most terrifying dragon to have ever lived.
- Dragons Are Dinosaurs: The Red Death looks like an unholy cross between a turtle, an ankylosaur and a large theropod, is as big as Godzilla, and worst of all, it can fly. The overall cast of the monster gives the feel of a leftover primordial dragon, or perhaps even an ancient dragon deity.
- The Dreaded: The dragons are terrified of this thing and visibly shake in fear when delivering it food. When it gets up to fight up the vikings, they run away in fear not wanting anything to do with it.
- Establishing Character Moment: The first thing this draconian monstrosity does on-screen is swallow a Gronckle whole for not meeting its feed quota. It follows up that appetizer with an entire Hideous Zippleback - in one bite.
- Evil Is Bigger: This guy is the only out-and-out evil dragon and it's HUGE.
- Extra Eyes: Further emphasizing its monstrous appearance in comparison to the smaller dragons.
- The Fagin: A monstrous draconic version of it. It forces plenty of smaller dragons to seek food to feed itself, lest they want to be devoured.
- Family-Unfriendly Death: Being set on fire from the inside certainly isn’t very kid friendly.
- Flat Character: While she has moments where It Can Think, the screen time it has doesn't give much room for personality, so in terms of character it's little more than an aggressive giant animal looking for food.
- Genius Bruiser:
- It's smart enough to know it'd get more food by forcing other dragons to work for it. When the vikings try to escape it after they find its lair? It destroys the ships so they can't.
- When it loses track of Hiccup and Toothless in a cloud, it sprays fire in every direction, which does manage to hit Toothless' prosthetic tail fin.
- Giant Flyer: It's as big as a mountain.
- Hero Killer: Very narrowly subverted - it nearly crushes Fishlegs underfoot after his Gronkle is downed, only to be distracted by Snotlout; it nearly swallows Astrid and her Nadder whole courtesy of its Vacuum Mouth, and it nearly torches Gobber and Stoick before being distracted by Toothless and Hiccup.
- Hidden Villain: As it never left its lair, the Vikings had no idea it even existed.
- Hive Queen:
- It appears to have some kind of influence over the dragons even at a distance. One scene all but spells this out when Toothless appears to endanger the lives of Hiccup and Astrid by taking them neck deep into the heart of the dragons' nest for no apparent logical reason. This also explains why the dragons don't just leave, because they have no choice. Astrid even Lampshades this, comparing the dragons' nest to a giant beehive ruled over by a queen.
- With the advent of the second movie, it might be an "Alpha" dragon, just like the two Bewilderbeasts.
- Horrifying the Horror: All the dragons that have terrified and attacked many a Berkian are afraid of this titanic beast that can eat them in an instance.
- It's All About Me: Doesn't care about the dragons giving it food and will eat them if they don't bring it enough to satisfy it.
- It Can Think: Despite her mostly animalistic behaviour, the Red Death does show occasional signs of higher intelligence and planning.
- The Juggernaut:
- It makes its entrance at the climax of the movie through a hole made in the dragon's nest by the vikings siege engines that wasn't big enough for it to fit through, plowing through the rock like it's not even there, then casually tanks several shots from the mountain-cracking catapults (which were previously shown as a serious threat to dragons).
- While the Red Death is chasing them, Hiccup and Toothless fly around, over and under large rocky outcroppings. The Red Death smashes right through them without so much as slowing down. Multiple shots from Toothless' fire (shown to be capable of breaking stone and steel alike) do nothing but knock it back slightly or cause it to flinch for a moment. It takes being set on fire from the inside-out, having its wings burned through, then slamming head-first into the ground from hundreds of meters in the air to bring it down.
- Kaiju: A dragon the size of a truck would generally be considered large in this setting. The Red Death can (and does) swallow those whole. In the books he eats a younger version of his own kind. Easy to believe, considering he considers normal dragons tasty snacks. For reference, he's as long as Legendary Godzilla is tall.
- Knight of Cerebus: Once it shows up, the film starts getting darker with The Reveal of why the dragons are stealing food which nearly drives a wedge between Hiccup and Stoick, to say nothing else of how it nearly killed the men who came to face it.
- Large and in Charge: The other dragons are like flies compared to it.
- Lightning Bruiser: It's astonishingly agile for its size when in the air, and turns surprisingly quickly, but it's still no match in that department to Toothless.
- Made of Explodium: Its breath is extremely flammable. Naturally, Hiccup exploits that to blow it up.
- Mighty Glacier: On the ground, it is rather slow and sluggish. However, it is not much of a disadvantage in the final battle, as the Vikings don't have anywhere to run to after it burned their ships. And when it takes into the air, it's faster than the looks.
- Mix-and-Match Critters: Its body resembles a turtle, the tail looks like an ankylosaur's, and has a head resembling a theropod, in addition to its bat-like wings.
- Monstrous Cannibalism: Perfectly willing to eat other dragons if given the opportunity, especially if they fail to bring enough food.
- More Teeth than the Osmond Family: While all the dragons have lots of teeth, it has a far more menacing set since it has a head like a theropod.
- Names to Run Away from Really Fast: Red Death. Assuming the thing doesn't reach your boats first.
- Nigh-Invulnerable: Catapults that managed to break down the side of a mountain and knock dragons from the sky merely annoy it; even the explosion from Toothless' Breath Weapon, which had been seen breaking rock and steel, did little more than knock it down for a few seconds.
- Non-Indicative Name: It's more of a sort of blue-grey in colour, though the name may be more to do with what happens whenever one shows up... A few rows of its unusual spikes are red in color as well. Maybe a similar case to the Yellow-Spotted Lizard, picking the least apparent feature for the name.
- Non-Standard Character Design: All the dragons in the first film have some cartoonish or outright goofy elements to their design. This thing has none of that, instead having a more monstrous dinosaur-like appearance.
- Obviously Evil: Looks more terrifying than the other dragons and eats them if they don't bring it enough food.
- One-Man Army: The entire nest of dragons would rather run than stay in the same place as it, and the whole Viking army couldn't scratch it.
- Orcus on His Throne: Is far too lazy to go looking for its own food, so it forces the dragons of the first movie to find food for it. It only bothers to get out of its lair when an army shows up on its door step.
- Spanner in the Works: To Stoick's entire plan to drive the dragons out of their nest, as he had no idea about this thing. The result was the Viking force being decimated, as the very annoyed Red Death sets their ships and siege engines on fire with a single breath and routs them in short order.
- Starter Villain: It is the first antagonist of the entire franchise, who is taken out by Hiccup and Toothless.
- Vacuum Mouth: Being as massive as it is, merely inhaling is enough to suck potential prey into its mouth, as it almost did with Astrid and Stormfly.
- Vile Villain, Saccharine Show: A lighthearted movie about a boy befriending a dragon has a giant voracious murder machine as its main villain.
- Villainous Glutton: Implied. The dragons it forced to find food for it could comfortably be supported by the same Vikings they were stealing from, giving the hint that Red Death ate more than all of them combined.
- You Have Failed Me: Its Establishing Character Moment has it eat a Gronkle for failing to bring it enough food.
Toothless’ Nemesis
Appearances: Dragons: Riders of Berk
A male Whispering Death had a history with Toothless and not a good one. They are willing to fight to the death. He is the first Whispering Death that appeared in the series and appeared in the episode "What Flies Beneath."
- Ambiguous Situation: How he and Toothless developed a nasty hatred for each other which is never explained.
- Arch-Enemy: He is this for Toothless.
- All There in the Manual: His name is only known from supporting material.
- Every Scar Has a Story: The Whispering Death has a scar in the shape of a Night Fury bite. Fishlegs and Hiccup conclude that Toothless and the Whispering Death are bitter rivals engaging in a Duel to the Death.
- Foil: To Toothless. While Toothless has retractable teeth, no spikes, has large wings, has legs and arms, and hunts from the sky, Whispering Deaths have many terrifying rotating teeth, many spikes, tiny wings, no arms or legs, and just a head with a long tail, and hunts from the ground. Also, in terms of combat, Toothless tends to emphasize stealth and hit-and-run tactics, while the Whispering Death ignores all subtlety and just digs and destroys anything that gets in its way.
- The Bus Came Back: Makes a surprise reappearance in Race to the Edge, the episode “Darkest Night”, but only in a flashback.
- What Happened to the Mouse?: Disappears for nearly the entire series, even after his first appearance, only to be seen again in a flashback.
Torch
Appearances: Dragons: Riders of Berk
First introduced in "The Terrible Twos"
Originally a baby Typhoomerang (a then-unknown dragon species) that Hiccup discovers, he eventually returns to his mother after a short misunderstanding. He later returns in "Zippleback Down", fully grown.
- The Bus Came Back: In "Zippleback Down".
- Flashback: How his true identity is revealed in "Zippleback Down".
- Gigantic Adults, Tiny Babies: When he was young, he was Terrible Terror-size. As an adult, he is larger than any academy dragon by two easily.
- He Is All Grown Up: In "Zippleback Down".
- Sibling Rivalry: Torch and Toothless can't stand one another. In "The Terrible Twos", Toothless resented Torch due to how much attention Hiccup was giving him. It got worse when he found out that his mother was looking for Torch, to which Hiccup mistook Toothless as hating him. However once Torch returned in "Zippleback Down", their rivalry seemed to have watered down, but only to where Torch will save Toothless if necessary. They will still bicker fiercely while in the presence of Hiccup.
- Took a Level in Badass: After growing to adult size Torch can carry three of the teens, Barf and Belch, and Toothless with ease. His firepower has increased as well.
Screaming Death
Appearances: Dragons: Riders of Berk
Introduced: "Tunnel Vision"
An offshoot of the Whispering Death, the Screaming Death is five times the size and proportionately dangerous. It gets its name from its dragon-disorienting scream, specifically coined by Tuffnut. And this dragon is a complete unknown, with no entry into the Book of Dragons.
- Asskicking Leads to Leadership: Has the command over several of it's Whispering Deaths siblings and hands Berk its ass on a silver platter without so much as trying.
- Brown Note: Its scream causes other dragons to become disoriented while commanding the loyalty of the smaller Whispering Death.
- The Dreaded: In his first appearance all the dragons were scared of it when it came out of the ground. By it's second appearance, Astrid is terrified of it.
- Even Bad Men Love Their Mamas: The motivation for his rampage throughout the season is to find his mother. Its mother is also just about the only thing that keeps it in check - its surprise appearance in Race to the Edge had it either forgotten or not care that Hiccup and the other riders had helped it before. However, its mother did remember and promptly got it to back off, despite being a fraction of its size.
- Expy: To the Red Death. Their names are similar, it has several dragons under their command, are quite large, can shrug off everything, and are antagonists. However, unlike the Red Death, the Screaming Death isn't strictly malicious and just wants to find its mother and be left alone - though it does have a monumentally bad attitude.
- Foil: To Toothless. While Toothless is Dark Is Not Evil, has a rider, and used to work alone, The Screaming Death invokes Light Is Not Good, has no rider, and commands its own dragons. In terms of combat, while they both have incredible power, Toothless tends to emphasize stealth and hit-and-run tactics, while Screaming Death ignores all subtlety and just smashes anything that gets in its way.
- Giant Mook: It's a larger version of the Whispering Death.
- Heel–Face Turn: Somewhat. Just not antagonistic anymore.
- It Only Works Once: When it returns it is no longer attracted to the light or at least learned to ignore it.
- Jerkass: Even after its sort of Heel–Face Turn, it has an incredibly bad attitude.
- The Juggernaut: Smashes through rock formations without even trying and can easily shrug off bombardment from a dragon like Toothless. For context, even the Red Death flinched at Toothless' plasma blasts.
- King Mook: To Whispering Deaths, which it can sometimes command. Except for its mother, which puts it in its place.
- Large and in Charge: It's larger than its relatives and commands their loyalty.
- Lightning Bruiser: Very fast and agile, can demolish rock formations and even islands, fires like a machine gun, and shrugs off everything.
- Light Is Not Good: A pure-white dragon that is downright vicious.
- Made of Iron: Rams headfirst through a bunch of rock pillars and then headlong into a giant rock formation, the latter only managing to knock it out for a few seconds. The collapsing rock face damaged its much more fragile wings, however, but it wasn't going to let it stop him. As it gets bigger, it even no sells the types of rock formations that almost got it killed in its first appearance and causes them to shatter into enough pieces it does not have to worry about its wings. It also takes the combined attacks of at least twenty dragons and shows no wear or tear from repeated spine attacks, fireballs, and being rammed by Gronckles.
- More Dakka: The Screaming Death shoots fireballs like a machine gun.
- More Teeth than the Osmond Family: Similar to the Whispering Death, but it doesn't have the Langolier-like mouth.
- No-Sell: Its scales are hard enough to fully protect it (and anybody who salvages them for armor) from arrows.
- Person of Mass Destruction: Can cave in and sink islands without breaking a sweat.
- Red Eyes, Take Warning: Fishlegs describes them as 'boring into your very soul', and there are worse descriptions for a dragon that is, at the very least, extremely destructive and incredibly bad tempered.
- Smarter Than You Look: Lampshaded by Hiccup when it realizes it was being distracted from destroying Dragon Island.
- Spike Shooter: Just like the Whispering Death, except they're spikes the size of spears.
- Super-Scream: The aforementioned Brown Note, disorienting dragons mid-flight while it screams. But fortunately, it does not cause sonic booms like the Thunderdrum.
- The Bus Came Back: Returns in a surprise one-episode appearance in Race to the Edge, where its scales get used as armor to defend against the Dragon Hunters' dragon root arrows.
- Also makes a cameo in the Grand Finale to answer the roar of the Bewilderbeast.
- Took a Level in Badass: If it wasn't bad enough, it ends up bigger and near-invincible in its second appearance.
- Tunnel King: Just like its smaller counterparts. Except as it grows, its capable of bringing down entire islands from its tunneling.
- Weakened by the Light: Played with. Despite being albino, it is attracted to light, instead of retreating from it. But, as Hiccup figures out..."Attracted to the light? That can be a weakness, too!"
- White and Red and Eerie All Over: Mostly white, beyond the blood-red eyes and tailtip. Is also a complete spook without any information on it in the Book of Dragons.
Windshear
Appearances: Dragons: Riders of Berk
Introduced: "Have Dragon will Travel, part 1"
Heather's Razorwhip dragon. She is a sharp class and has a lot in common with Deadly Nadders including throwing tail spikes, but looks a lot sleeker and seems to have a coating of metal all over her body.
- Absurdly Sharp Blade: Her tail spikes are sharper than anything man-made.
- Extra-ore-dinary: Her body is covered in metal including the tail spikes that she can shoot. Heather has turned some of the spikes into bits of armor for her arms and shoulders.
- Meaningful Name: Explained by Tuff, she "rides like the wind, shearing through it."
- Morality Pet: Hiccup is able to use Heather's love of Windshear to get the girl to stop acting so suicidal.
- Recruitment by Rescue: A non-villainous example, Heather found Windshear after the dragon had been injured and Heather nursed her back to health, afterwards the two became inseparable.
- Spike Shooter: Like the Nadder, Razorwhips are able to shoot tail spikes.
- Uncatty Resemblance: She's skittish and has a hard time trusting people, but is a fiercely loyal friend if she does, just like Heather.
Shattermaster
Appearances: Dragons: Riders of Berk
Introduced: "Family on the Edge"
A green Gronckle picked out to be Dagur's mount.
- Keet: Shattermaster is very energetic.
- Morality Pet: Besides Heather, Shattermaster also helped Dagur change for the better.
- Papa Wolf: He's also shown to be quite protective of Dagur, as seen when Astrid threatened to harm his rider if he betrayed them.
- Undying Loyalty: To Dagur, actually willing to fight other dragons if they threaten him. The Riders are genuinely surprised by how quickly the two bonded.
- The Bus Came Back: Makes a cameo in Dagur's wedding.
- What Happened to the Mouse?: Disappears entirely in Season 5 of Race to the Edge. He shows up alive and well in the final episode though.
Sleuther
Appearances: Dragons: Riders of Berk
A Triple Stryke was captured by Ryker and forced to fight in an arena. After being freed by the Riders he followed them to The Edge before bonding with Dagur.
- Ascended Extra: Becomes Dagur's mount in Season 7.
- Animal Motifs: The tails and pincers are strongly reminiscent of a scorpion, while the color scheme seems more like a wasp.
- Beware My Stinger Tail: Three tails that end in scorpion stingers. He can hold them together to act like a single tail.
- Breath Weapon: Fire, though he prefers to get up close and use his tails.
- Bright Is Not Good: He has a bright yellow and black color scheme. Averted after he is freed from the arena.
- Defeat Means Friendship: A bit of a tricky example. After being defeated and freed he happily leaves with the riders but remains hostile due to his experiences with humans. He doesn't become a true ally until the riders manage to start training him.
- Red Eyes, Take Warning: Bright red eyes and first appeared as a vicious area combatant.
- Uncatty Resemblance: Just as vicious and unpredictable as his rider, Dagur. As well as starting off as an enemy before becoming an ally.
- What Happened to the Mouse?: His introduction episode ends with him following the riders back to their base, with Hiccup promising that he'll like it there. He isn't seen until next season, where it's revealed that he's been roaming the island and avoiding the riders. The season after that, he has become Dagur's mount, amicably shoving his previous dragon, Shattermaster, into this role.
Bing, Bam and Boom
Appearances: Dragons: Riders of Berk
A trio of young Thunderdrums that start wreaking havoc across Berk. After attempts to train them fail, Stoick releases Thunderdrum so that he can watch over them.
- The Bus Came Back: In the School of Dragons game, they're discovered locked in the hold of the Reaper and along with Thunderdrum move into the school. They also accompany Thornado when answering the call of the Bewilderbeast.
- Not Allowed to Grow Up: Although dragons in the series are established to have pretty quick childhoods, they haven’t aged a day when they return to aid the Bewilderbeast’s call, even though at this point in time, 4 years have passed.
- Palette Swap: All of them have the same character model, but with different colors. Bing is teal, Bam is blue, and Boom is purple.
- Ridiculously Cute Critter: As with all baby dragons in the franchise, these three are basically chibi versions of Thunderdrums and are thus quite adorable.
- Sidekick Creature Nuisance: Though cute, they're also extremely noisy and cause many problems for the inhabitants of Berk while they're around.
Garffiljorg
Appearances: Dragons: Riders of Berk
A Deathsong the Dragon Riders hatch out of an egg and raise, before leaving it with the adult Deathsong on Melody Island after he becomes too much of a hassle.
- Badass in Distress: Hiccup and Astrid find him badly wounded after a tussle with the dragon hunters.
- The Bus Came Back: Returns around a season after his initial appearance, fully grown and extremely injured after a run in with Krogan and his dragon hunters. He came back in season 6 and plays a role in the series finale.
- Four Legs Good, Two Legs Better: He alternates between moving on two legs and four legs.
- He Is All Grown Up: He appears as a mature individual when he returns in Season 5.
- Platonic Life-Partners: With Stormfly, who even becomes immune to his song.
- Ridiculously Cute Critter: Young Garff is very, very cute.
- Sidekick Creature Nuisance: However, similar to Bing, Bam, and Boom, he's also extremely loud and keeps trying to prey on Chicken, Smidvarg, and the other Night Terrors.
- Vibrant Orange: He is very playful as an adult dragon, and even becomes close friends with Stormfly.
Darkvarg
Appearances: Dragons: Riders of Berk
A member of the subterranean colony of albino Night Terrors that Fishlegs discovers. Darkvarg bonds specifically to Fishlegs and is the only one to not turn on him when he tries to leave.
- The Bus Came Back: Returns when Fishlegs wanders back into the Night Terror caverns when trying to escape Krogan's Dragon Flyers. This time around, he's managed to become the leader of all the other Night Terrors and sics them on the Flyers at Fishlegs' command.
- Token Good Teammate: The only Night Terror actually loyal to Fishlegs, to the point of working against the others when they try to stop Fishlegs from leaving.
- Undying Loyalty: To Fishlegs.
Scauldy
Appearances: Dragons: Riders of Berk
A Scauldron the Riders find beached and go to great lengths with rescue, causing it to bond with Ruffnut in the process.
- A Lizard Named "Liz": Scauldy is a Scauldron.
- Badass in Distress: Is found beached and dying of dehydration, as well as having a wing broken and pinned under a boulder. Things go from bad to worse when a pack of hungry Changewings arrive.
- The Bus Came Back: Makes a small cameo in the spin-off game School of Dragons.
- Defrosting Ice Queen: When the dragon riders try to help him at first, he is extremely hostile towards them. Hiccup and Fishlegs even almost consider leaving him to die due to just how uncooperative he was. Slowly but surely, he develops a liking to Ruffnut thanks to her tenderness towards him (and her fish-smelling hair).
Snuffnut
Appearances: Dragons: Riders of Berk
One of the Changewings that arrives on the Edge for the annual Changewing migration, Tuffnut frames it to make it look like it ate him in order to fake his death so that Ruffnut would feel free to marry Throk. Ruffnut instead paints a picture of Tuffnut on its chest, names it Snuffnut, and declares to remain with it forever, leading to Throk trying to tame it.
- Badass in Distress: Despite being the episode's Monster of the Week along with the other Changewings, they turn on him when his invisibility is ruined by Ruffnut's painting, forcing the Dragon Riders to try and save him.
- Fall Guy: Gets framed for Tuffnut's death, leading the others to think it ate him.
- Spanner in the Works: The painting of Tuffnut on his chest foils his camouflage, causing the other Changewings to shun him. This in turn is a spanner in the Riders' attempts to drive the Changewing migration on to the next island since they won't leave without Snuffnut, but refuse to travel with him either.
Groundsplitter
Appearances: Dragons: Riders of Berk
A female Whispering Death trained by Alvin, who is also the mother of the Screaming Death. After the Dragon Riders release her, she and the Screaming Death retreat to a remote island to live in seclusion.
- All There in the Manual: Her name is only known from supporting material.
- Big Damn Heroes: Remembers Hiccup, Toothless, Snotlout and Hookfang from when they saved her from the Outcasts, leading to her defending them from the Screaming Death, who has forgotten this.
- The Bus Came Back: Makes a surprise reappearance, along with her monstrous son, in Race to the Edge.
Wingnut
Appearances: Dragons: Riders of Berk
A Razorwhip baby that confuses Ruffnut for a Wingmaiden, resulting in her having to train to become one.
- Back for the Finale: Shows up along with Atali in the final battle.
- Leap of Faith: One of the training missions is flight with a Razorwhip baby. Since Ruffnut doesn't have any experience in this, it amounts to this for her.
The Light Fury
A Light Fury who is introduced in the third movie and becomes Toothless' mate.
- Babies Ever After: Has three babies with Toothless by the end of Hidden World.
- Changed My Mind, Kid: She's had next to no positive experiences with humans. She eventually carried one to safety, however.
- Character Development: The Light Fury starts off as distrustful towards humanity since she was kidnapped by trappers, then given to Grimmel to use as bait. Her interactions with Hiccup and Astrid (especially the former) has her trying to kill them thinking they were dangerous. However, after seeing Hiccup's selflessness to protect Toothless, the Light Fury returns the favor to save him. And in the epilogue, she eventually comes to trust Hiccup, and by extension, his family to be around her mate and offspring.
- Dark and Troubled Past: How she ended up imprisoned by trappers is not touched upon, but it increased her distaste towards humanity.
- Female Feline, Male Mutt: With Toothless. Behaviorwise, Toothless has always been more or less both a dog and cat. The Light Fury, on the other hand, is 100% cat.
- Honey Trap: Zigzagged. Grimmel releases the Light Fury because he knew that Toothless would be attracted to her, and that Furies mate for life. However, unlike most examples of this trope, the Light Fury has no loyalty to Grimmel and is unaware of his plans. And she does become mutually attracted to Toothless, but her following him back to New Berk does allow Grimmel to briefly capture her, Toothless, and every Berk dragon.
- Interspecies Romance: With Toothless, a Night Fury. DeBlois commented that the Light Fury is not actually a Night Fury, just a similar related species. This doesn't stop Toothless from courting her, and later, their mutual attraction.
- Mama Bear: When all three of her offspring snuck off to New Berk, she and Toothless immediately departed from the Hidden World to find them.
- Masculine Lines, Feminine Curves: With Toothless, who has straighter and more angular features; whereas she is softer and rounder in appearance.
- Messy Male, Fancy Female: She does not have any fur, but her skin is smooth and nearly featureless compared to Toothless and most other dragons with their textured scales.
- Neutral No Longer: For most of the film she distances herself from all humans - both the hunters who enslaved her, and the tamers of Berk. Notably, she is one of the few dragons in the series to never have a rider. But when she sees Hiccup sacrificing himself so she can save Toothless, she flies off to catch him before he hits the water.
- No Name Given: According to
Word of God, her lack of a name is a stylistic choice to symbolize her wildness. - Pale Females, Dark Males: With Toothless. While he's a black Night Fury, she's a white Light Fury.
- Pink Means Feminine: Under certain lighting conditions, she sports faint pink stripes.
- Straight Man: Compared to Toothless' lovestruck enthusiasm and ignorance of Fury ways.
- Violently Protective Girlfriend: When she thinks that Hiccup is harming Toothless, the Light Fury snatches him from the latter's back and tosses him into the ocean.
Dart, Pouncer, and Ruffrunner
Pouncer (left), Dart (middle), and Ruffrunner (right)
A trio of Night Lights who are the hybrid offspring of Toothless and the Light Fury.
- All There in the Manual: Their names are spoken in the RPG-style game School of Dragons.
- Foolish Sibling, Responsible Sibling: Dart is more reckless than her brothers, but also far more intelligent and curious; the latter are only interested in squabbling and sleeping.
- Gender Equals Breed: Averted; Pouncer looks more like the Light Fury, but is a boy, while Dart looks mostly like a Night Fury, but is a girl. Ruffrunner on the other hand looks the most like his father with his green eyes and darker coloration.
- Intrigued by Humanity: Unlike her brothers who loaf about, Dart is endlessly curious about Hiccup and the vikings.
- Pale Females, Dark Males: Subverted; Pouncer is a boy despite his great resemblance to his mother. Dart on the other hand is a girl even if she looks more like her father. Ruffrunner plays this more straight though.
- Patchwork Kids: They are a mixture of both Night and Light Fury dragon species.
- Sleepyhead: Ruffrunner tires easily and has a habit of falling asleep.
Modern Day
The Fault Ripper
Appearances: Dragons: The Nine Realms
A large, blind dragon with the ability to drill through rock.
- Back for the Finale: It, alongside the Sky Torcher, is recruited by Thunder to fight Jörmungandr. With its help, the Apex Predator can be defeated.
- Crippling Overspecialization: Its hearing is excellent to make up for its lack of eyesight, but certain dragons have sonic attacks that will send it spinning away.
- Handicapped Badass: Despite this species being blind, Fault Rippers are able to dig efficiently and can put up a good fight when threatened.
- Scary Teeth: It has long needle-like teeth sticking out of its mouth.
- This Is a Drill: By spinning on a horizontal axis, it can burrow through solid rock.
The Sky Torcher
Season 1-7 (left), Season 8 (right)
Appearances: Dragons: The Nine Realms
A very large Stoker Class Dragon that commands the Flame Throwers.
- Fangs Are Evil: It has two very long fangs growing out of its upper and lower jaws.
- A Father to His Men: It goes into the ice realm, an area that slowly drains its stamina and firepower, to rescue the Flame Throwers trapped by Buzzsaw.
- Giant Flyer: It has a very long body and is much bigger than any dragon the Dragon Club has encountered.
- Good Scars, Evil Scars: The Sky Torcher is covered with scars and bite marks from its Curb-Stomp Battle with Jörmungandr.
- Herd-Hitting Attack: It breathes four streams of fire from its mouth rather than just one, giving it a wider range of attack.
- Light Is Not Good: It is a giant white dragon that dominates over other species with aggressive tactics.
Old Jack
Appearances: Dragons: The Nine Realms
A Timberjack forcibly tamed by Buzzsaw.

The Apex Predator of all dragons who was caged in the Dark Realm by Hiccup using Valka's staff. He was set free by Thunder when Tom was about to be attacked by the Sky Torcher and proceeded to go on a rampage throughout the Hidden World.
- Batman Gambit: In the finale, Jörmungandr attacks the Night Lights, knowing the riders would stay and protect them. This gave the Apex Predator the opportunity to attack the God's Realm without interference.
- Big Bad: Of the 8th Season of Dragons: The Nine Realms. His presence and threat is felt throughout the season both directly and indirectly.
- Breath Weapon: Jörmungandr breathes out poisonous, light blue smoke that severely weakens anyone who inhales it.
- Electricity Knocks You Out: In the finale, after having been weakened by the Spam Attack of the dragons, Jörmungandr is finished off by Thunder channeling his lightning through Tom's sword, shooting it out as a beam and electrocuting the Apex Predator into unconsciousness.
- Final Boss: He is the last threat in the series, and the reason the riders must defeat him.
- The Great Serpent: While not big enough to wrap around the world, Jörmungandr is still big enough to prey on a dragon as big as the Sky Torcher.
- Horrifying the Horror: After Jörmungandr invaded the territory of the Glass Caster, a usually extremely territorial and dangerous dragon, the Glass Caster has become so frightened, it cowers before the riders when they enter his territory.
- Knight of Cerebus: The moment Jörmungandr is released there is a tonal shift as it immediately bites down on the Sky Torcher's neck and drags it into its former prison before it crashes through the gate out of the Dark Realm into the rest of the Hidden World.
- Monstrous Mandibles: His lower jaw can split into two halves.
- Nearly Normal Animal: Even among the already smart dragons in Dragons: The Nine Realms, Jörmungandr stands out in terms of cunning and intelligence. While appearing more like a vicious animal bound by its natural predatory instincts to hunt and kill any dragon it crosses paths with at first, it has been shown to be able to learn, recognize and avoid traps and even formulate strategies such as when it pulled a Batman Gambit on the riders by attacking the Night Lights as a distraction for its real target, the God's Realm, the so-called "lungs" of the Hidden World were most of the Hidden World's oxygen is produced. Even the riders who already treat dragons as their equals are taken aback by Jörmungandr's cunning.
- Nigh-Invulnerability: It shrugs off most attacks thrown at it. In the end, it takes a small army of dragons, including the Fault Ripper and Sky Torcher, attacking at once to defeat it.
- Oh, Crap!: When Thunder faces Jörmungandr for the last time, now glowing blue symbolizing his ascension to the rank of Alpha, Jörmungandr looks surprised with a trace of fear in his eyes. Once Thunder commences the Spam Attack of his small force of dragons, the Apex Predator tries to run away rather than fight.
- Predators Are Mean: Like other dragons who hunt other dragons, Jörmungandr is portrayed as being bad. In fact, the Apex Predator even serves as the Big Bad in the final season.
- Really 700 Years Old: He was originally caged by Hiccup, meaning he is over 1,000 years old.
- Won't Get Fooled Again: When Tom manages to get Jörmungandr to the gate of his prison using Valka's staff, his fragile control over the Apex Predator slips as soon as it recognizes Tom doing the exact same thing Hiccup did to imprison it and attacks Tom, stealing and subsequently breaking the staff.
