Adorkable: There's been plenty of fan gushing at how cute the geeky Hiccup is. This should really be expected when he's voiced by Jay Baruchel.
Aesop Amnesia: In "Terrible Two" he causes problems because he trusted a strange dragon over Toothless. He didn't learn his lesson because in "Heather Report" he trusted a strange girl over Astrid. Downplayed in "We Are A Family Part 2" where he is very reluctant to trust Mildew but ultimately does so. Like the previous occasions, this is a horrible idea because Mildew used him to learn dragon training which he passed onto Alvin. A storyboard of an unused intro by Hiccup says this has less to do with amnesia and more to do with Hiccup simply being too trusting.
All-Loving Hero: Believing that humans and dragons can coexist will definitely make him this. Deconstructed in the series, where his habit of trusting people immediately has led to problems.
All of the Other Reindeer: Nobody likes him; he's the village pariah because he's scrawny and usually messes everything up. In keeping with the trope, things get better for him after he ends the Dragon Wars.
Amazon Chaser: A large part of his crush on Astrid is because of her Action Girl-ish qualities. Take a look at her introduction: she's fighting dragons amid flames and Hiccup has the 'hearts in his eyes' expression.
Artificial Limbs: Hiccup loses his left foot during the battle with the Green/Red Death in the movie. It's replaced with a metal prosthetic. Leads to Angst? What Angst? as he seems to adjust to it very quickly; in the series other characters make a bigger deal out of it than he ever does.
Badass Pacifist: His role in the movies, since the "Vikings vs. dragons" conflict doesn't exist in the books. His ability to tame dragons comes from Hiccup being friendly instead of defending himself. This takes more courage than killing them on sight.
Badass On Paper: He looks like a scrawny teenage kid with a knack for inventing, but he did create the art of dragon taming, ended the war, and instigated the demise of the Red Death.
Badass Teacher: Slowly becoming the second part as the main teacher of the Dragon Academy.
Underestimating Badassery: A lot of people tend to think Hiccup is just the scrawny, nerdy, weirdo...then they actually see him in action.
Fluffy Tamer: While giving them names like 'Toothless' and cuddling them.
Bigger Stick: Discussed. His friends sometimes wonder how much of his success is due to his own skill, and how much is due to being the rider of an absolutely fantastic dragon. Of course, when they attempt to test this by having the group train Terrible Terrors, Hiccup quickly teaches his to blow things up with impressive accuracy.
Black Sheep: In the movies, as an inventor and scientist in a society of warriors.
Born in the Wrong Century: In the 21th century here, Hiccup might be bullied, but at least he'd have a niche in society where he belonged, and his intelligence would be recognized. In the films' setting, he's treated as a child and disowned by his family and tribe for trying to train a particular species of animal instead of killing it on sight. Instead, he has to make his own niche.
Classical Anti-Hero: Originally a Type one, a wimp who nobody really likes. Compared to the paragon hero his father acts like, Hiccup's runtiness is constantly mocked. Even his ingenuity in making newer weapons was mocked because while being smart about hunting and trapping and killing dragons is a good thing, none of what Hiccup created seemed to work. Eventually, he accepts himself and all his flaws, turning them into his strengths and would become a hero in the eyes of his village.
Cowardly Lion: In the books; understandable since he's only about ten.
Crazy-Prepared: Justified though experience. He carries a complete set of spare parts for Toothless' tail fin at all times.
Hiccup:"I'm the first Viking who would not kill a dragon!" Astrid:"First to ride one, though."
Expecting Someone Taller: Alvin couldn't believe that the famous "Dragon Conqueror" was 'Stoick's little embarrassment'.
Shrouded in Myth: It's implied (in the Portrait of Hiccup episode) that no matter what Hiccup does, Viking mythology in the future will portray him as a fearless, tough, fire-breathing badass admired by everyone- because that's what Vikings do. They make awesome ballads out of their heroes' exploits even if they must warp the truth to do it. Hiccup finds this exceedingly depressing: he spent his whole childhood ignored and degraded because he didn't fit Viking standards of strength.
Friendless Background: Except for Gobber, Hiccup had no friends, that change during the course of the first movie.
Gadgeteer Genius: He can make an interlocked tail fin for Toothless centuries ahead of when such technology was possible. This may be a reference to the books, where Vikings have fully-operational STEAMSHIPS, hot-air balloons and gliders well before the Industrial Revolution.
The trailer for the sequel film shows him using a fully functional wingsuit!
In Defenders of Berk, he designs a shield. Initially it simply fires a grappling hook, but once upgraded with Gronckle Iron it would put Howard Stark and his designs for Cap to shame. Among the functions it has, it can deflect large numbers of throwing daggers and crossbow bolts, fire the aforementioned grappling hook, and also transform into a crossbow.
Graceful Loser: Discussed. In "Thawfest", Astrid said this was his most admirable trait in her eyes when he began acting unpleasant at the thought of winning the games just to spite Snoutlout.
Green Eyes: Showcasing his Brains over Brawn compared to the other Vikings
Guile Hero: Stoick wants him to be an Action Hero, but Hiccup is much better with smarts and cunning. In fact, it was due to his intellect that he was the first person to solve a poem-based puzzle that nearly destroyed Stoick's and Gobber's friendship. This was because the puzzle was created by a Guile Hero himself.
That said, Hiccup has become quite capable physically by Defenders of Berk, facing off with Dagur the Deranged in single combat while Toothless was trapped by bolas.
More Dakka: Has a particular fondness for using this in dragon combat, bombarding the enemy with a hail of highly accurate shots. It becomes obvious that this is his preference rather than just a Night Fury thing when he trains a Terrible Terror to do it as well.
Nice Guy: Hiccup is kindhearted, easy going and always willing to help.
Beware the Nice Ones: Keep in mind he ended the war with the dragons by killing the Red Death, and he is very protective of his dragon and friends. Dagur the Deranged discovered this the hard way.
With Stoick. It takes a while for both to realize they have the same hardheaded tendencies about things they truly believe and won't listen to arguments against it lightly.
With Toothless. A significant turning point in the film is when he musters up the courage to look into Toothless' eyes. Upon seeing the fear there, he realizes that dragons are not, as he'd been taught from childhood, a mindless Always Chaotic Evil race that wants to kill everyone.
The Southpaw: Shown subtly in the film, which is accurate to the book portrayal. Hiccup writes with his left, and any closeups on his control of Toothless' prosthetic tail-fin are on the left stirrup. His clumsiness may be a factor of having to use right-handed objects, or his weak hand, or both.
Squishy Wizard: Subverted. Snotlout and several others assume Hiccup would be useless without Toothless, but it turns out Hiccup is still quite capable on his own and can kick ass using just his smarts and tools.
Speaks Fluent Animal: In the books he's able to understand and talk to dragons based on long periods of observation. The movie follows a similar path; he can't talk with dragons, but he can communicate his feelings to them very well, and this is because he's compassionate and patient enough to look for intelligence where everyone else sees evil.
Stepford Snarker: It's heavily implied that the main reason Hiccup is so sarcastic because it was a way to deal with the constant shunning from his tribe, teasing from his peers, and disappointment from his own father. Now sarcasm is just another part of his character.
Genius Ditz: He's a prodigy at everything relating to dragons and inventing but little else. In a pre-modern world where dragons are a source of speed, protection and martial ability far above anything technology can supply, this is very useful.
Teens Are Short: In the films, Hiccup is seen as the shortest teenager in his village.
Took a Level in Badass: In both the books and film and even more so in the books, where he started off as a scrawny shy boy that no one notices except when he messes up, and grows into a talented sword fighter and dragon whisperer who's saved the Archipelago several times and is prophesied to one day become the King who will unite the tribes again.
He graduates into a fully-fledged Badass in the TV show given he now leaps into highly dangerous situations in a calm demeanor and is trying to become a Badass Teacher by running the Academy.
Weak, but Skilled: Hiccup is a very scrawny Viking compared to his more physically-capable friends, but he makes up for it with good application of his brains and tools. Case in point, he curb-stomps Dagur the Deranged.
In the movie, Hiccup points out how ridiculous his name is, but explains the reasons for awful names (scaring off gnomes and trolls) and says that there are other people with worse ones.
In one episode of the series, Hiccup mentions that it's traditional to call the runt of a litter a 'Hiccup'. It ends up being a key point later in learning he wasn't the first chieftain son to be a Hiccup either.
Hurt anyone he cares about, be it his son, village or his dragon, and you're in big trouble. This is ESPECIALLY true in the books as seen when Skullion's (A species of vicious eyeless dragons) soon discover when they were about to harm Hiccup.
He reacts badly to people who mock those he does respect. Dagur almost finds this out violently three times in the span of a day.
On a less extreme angle, he gets somewhat irritated when somebody makes a remark about his weight. Or interprets a statement as one about his weight.
Birds of a Feather: He and his dragon, Thornado, are quite stubborn. This is something Hiccup is quick to comment on.
Character Development: He starts the movie as a dragon-killing viking. Any good dragon to him would be a dead one. But he comes to see them not just as trainable beasts but close allies. His worry for Thornado when he was ill in "Dragon Flower" and later telling Gobber he would rather kill Dagur than allow him to kill Barf and Belch and risk war with the Berserkers in "Twinsanity" shows exactly how far he has come from the movie.
The Cobbler's Children Have No Shoes: In Riders of Berk, Stoick rises before dawn to sort out other people's problems (from marital disputes to yak-tipping) until sunset, which implies that he had less time to spare for his own son.
Collector of the Strange: In "We Are Family part 1" it reveals he enjoys woodcarving as a hobby. He was carving a duck when Astrid came to the house early in the morning.
Dad the Veteran: He, like other adults, has spent his life in the war against the dragons before his son ended it.
Genre Savvy: When he and the vikings attack the dragon's nest, all the dragons immediately flee from the island. While the rest of the vikings are quick to celebrate their "victory", Stoic, upon seeing Toothless' reaction, realized something far worse was on its way.
The Good King: He genuinely cares about his village and seeks to keep them safe and well. If he has to make a choice between personal and his duty as chief, the later comes first.
"Look at that...All my people are safe. It's a good feeling."
He Who Fights Monsters: His drive to protect his home from dragons led him to invade the dragon's home to kill them. He eventually turns around.
Huge Rider, Tiny Mount: Before looking for his own dragon, he "borrows" Toothless from Hiccup and looks very awkward riding such a small dragon, and Toothless is dead tired after flying him around. Averts this when riding Thornado.
I Have No Son: In the movie he says "You're no son of mine" after Hiccup publicly refuses to kill a dragon, and is revealed to have been working with Toothless. During the final battle he realizes his mistake and he tells Hiccup "I'm proud to call you my son."
I Need a Freaking Drink: Shown when he comes home stressed in "Viking for Hire" and Hiccup quickly gets him a drink from a tankard.
Jock Dad, Nerd Son: He's always wished that his son had more beef on his arms but he comes to respect the "nerd" aspect of it as it helps him become a better chief.
Large And In Charge: He's the biggest and broadest viking, (400 pounds according to Hiccup, though that may have been exaggerating), and his beard is the biggest too.
Being as large as he is, this leads to a particular funny moment.
Hiccup: But there are two of you. Stoick: Is that another crack about my weight?
The Leader: Type levelheaded. He gives the dragons the benefit of the doubt but if they become a threat to his people he has to deal with it.
Made of Iron: The man takes the sharp end of an ANCHOR to the face in his fight with Alvin the Treacherous, shrugs it off, and afterwards there's not a single scratch on him!
Then in Live and Let Fly, he catches a rock launched from an Outcast catapult and throws it back at the ship.
Despite Hiccup's status as 'village failure', Stoick is still quick to protect his son from danger.
After he gets Thornado, this extends to him (and probably the other dragons). When he realized Mildew had poisoned them, the look on his face is one of pure hatred. Probably the only thing keeping him from beating the stuffing out of Mildew himself was he had no way to prove he intentionally poisoned the dragons.
Reasonable Authority Figure: He tries to do what's best for everyone. Mildew uses this to his advantage when confronted for something he obviously did by using the fact there is no evidence, especially concerning the affairs of Dragons, to get away with it.
Royals Who Actually Do Something: Takes his role as chief of Berk very seriously and is often one to lead the charge. It's also shown in two episodes that he spends his days "chiefing" which involves everything from settling disputes and inducting babies to the tribe to fixing ships or removing fences.
Zigzagged in the movie. Initially disappointed, then proud when Hiccup demonstrated his dragon knowledge, then outraged when Hiccup refuses to kill dragons, then proud again during the final battle.
Also zigzagged in the series but to a lesser extent. There are some kinks to work out in relation to the dragons and while he's more accepting of his son's scrawny stature he'd still prefer him to be buff and strong.
The Stoick: It's his name, after all. While he is a man of few words, he clearly cared about his son even at the beginning of the movie.
Hiccup:[sarcastically imitating Stoick] Excuse me, barmaid! I'm afraid you brought me the wrong offspring! I ordered an extra-large boy with beefy arms, extra guts and glory on the side! This here, this is a talking fishbone!"
Drill Sergeant Nasty: He's in charge of training the new recruits; his approach is yelling suggestions while they duck and weave.
Gadgeteer Genius: He can make working flame throwers, though since dragons exist this is probably easier to achieve than in real life medieval times.
Ditzy Genius: Yet he has shown his mind is sorta out there, such as attaching said flame thrower to the harness of a fire breathing dragon.
Genius Bruiser: In the movies he's the village blacksmith and second only to the Chief in combat.
Handicapped Badass: He may lack an arm and a leg but that doesn't slow him down when it came to fighting dragons. He even stayed with Stoic to delay the Red Death.
Hates Baths: It takes the Stoick and the dragonriders with their dragons to force him into a tub. He smells so bad after a whiff a Terrible Terror flies disoriented and hits a wall.
Honorary Uncle: Hiccup was his apprentice, and Gobber took care of him as much as Stoick did. This is historically accurate. Nordic people would frequently ask allies to foster their children as a sign of deepest trust.
Jerkass: His portrayal in the books is nastier than the movie or series.
Number Two: He's Stoick's best friend and the one he turns to first for help but he made a mess of things when filling the role officially.
Running Gag: Numerous mention of or jokes involving his undies.
His belief for the first day of training in the film is to release a Gronkle, then ask the students what they know about it.
Gobber's father was also an example as he taught Gobber to swim this way. Sadly, this doesn't translate well to training the dragons at the academy. Oddly, Gobber seems to remember this fondly.
Shield Bash/Luckily My Shield Will Protect Me: His training sessions often include the merits of shields. In the movie, he said he would choose a shield if given a choice between it and a sword because the shield can be offense and defense.''
That Came Out Wrong: Never admits so himself, but his advice never carries out the intended message.
Voiced by: America Ferrera (film and TV series)
Action Girl: She's a skilled Viking and originally first in her class. She always takes the front lines in the film. In the series, she's the only one to attack Alvin the Treacherous (Snoutlout chickened out), despite the fact that he's a match for Stoick and thus way out of her league.
Always Second Best: To Hiccup for Dragon Fighting and then Dragon Riding. She doesn't mind it anymore in the series. To Snotlout for axe-throwing - she is very skilled, but it is mentioned that Snotlout always won the Thawfest festival, though if this year is the norm, that can be blamed by other candidates messing up her throws. This year it is Fishlegs.
Anger Born of Worry: She tends to get very angry at Hiccup when he does something incredibly foolish and not think things through.
Armor-Piercing Question: Astrid is good at these, first asking Hiccup why he is acting so oddly and discovering Toothless as a result. She then breaks him out of a Heroic BSOD by asking why he didn't kill Toothless when he had the chance.
Blood Knight: A more child-friendly example. She's fearless and enjoys the respect that other villagers give her for being good at fighting but she takes battle seriously and is the Only Sane Woman among the riders.
Call Back: In Fright of Passage, she directly quotes her dead uncle's last words before the Flightmare killed him.
In-film, she is suspicious of the worst-performing student suddenly rising to the top of the class and investigates Hiccup accordingly.
In the series, She is suspicious about the conditions surrounding Heather's back story, and gets more so once she spots her out in the middle of the night. She ends up being correct on her status as being a threat.
Girly Bruiser: If her performing acrobatic jumps on the back of her dragon is any indication.
Snotlout: "When the Flightmare comes, the Hofferson's freeze. Right Astrid? You are a-" (Astrid hurls a greataxe that almost kills him) "Hofferson..."
Fishlegs: "Legend has it that the Flightmare is so terrifying it actually freezes its prey in their tracks." Snotlout: "Yeah, just ask Frozen Fin Hofferson, right Astrid?" (Astrid slams him into the ground and puts her boot on his face)
The Lancer: To Hiccup, both at the Dragon Academy and life in general. While Hiccup has Geek Physique, she is the picture of an ideal viking warrior; aggressive, strong and skilled in combat.
Leitmotif: An excerpt from "Romantic Flight" plays during her introduction; violins are also a recurring instrument for her.
Lethal Chef: For all her fighting talents, it would seem Astrid cannot cook. In Gift of the Night Dragon, her Yaknog is so bad that even Hiccup (who swallowed raw, regurgitated fish) spat the stuff out.
Master of Disguise: She's able to pass herself as Heather when infiltrating the Outcasts and manipulate them into giving her the book of dragons and a dragon to escape on. It would have worked, except that the real Heather wasn't lying about her parents being held prisoner.
Meaningful Name: "Astrid" is an old Norse name meaning "Divine Beauty". Hiccup is clearly awestruck during her introduction in the movie, and Snoutlout also tries to get her attention. Astrid is also partnered with a Deadly Nadder, the most beautiful dragon species.
In the movie, this is Astrid's role in the climactic battle; directing the rest of Hiccup's flying corps in the fight against the Red Death while Hiccup tries to free Toothless.
In the series, this is her position in the Dragon Academy because she's the second most skilled and no one's brave enough to tell her otherwise.
Only Sane Woman: Compared to the other trainees in the film, she is the only one to keep her cool and not lose herself to some quirk or another. This extends to the television show, usually sharing it with Hiccup (most of the time).
Peek-a-Bangs: As pointed out in the DVD commentary, her pushing back her bangs later on in the story signifies her being open with her feelings, especially around Hiccup.
Pint-Sized Powerhouse: Is seen carrying a sheep on her shoulders about the same size as one which Snotlout is carrying.
Tomboy: An odd example because Berk is the land of dragon killing vikings. A rough attitude and enjoying competition is normal in such a place and so would be expected.
Tsundere: Type A in the movie; tsuntsun to everyone with deredere emerging later. In the series she mellows into type B. A typical example there would when an event touches on her affection for Hiccup she'll blush and then punch his shoulder as if to deny it.
A less-than-typical example occurs in "The Thawfest Games." After calling Hiccup out on being a bad winner, she punches his shoulder and then kisses him for doing the right thing; letting Snotlout win and keep his family's tradition.
The World Is Just Awesome: Seeing this while on Toothless with Hiccup helps her realize dragons are not the chaotic evil she had been raised to believe and Hiccup had deeper hidden depths than she realized.
Voiced by: Christopher Mintz-Plasse (film and TV series)
Beware the Nice Ones: Snotlout found out the hard way that Fishlegs is downright terrifying when pissed off. It's possibly a nod to the books, where Fishlegs became a flat-out berserker.
Deadpan Snarker: In the books. Sometimes dabbles into this on occasion in the series itself.
Demoted to Extra: While he was Hiccup's best friend in the books, he's more of a friendly classmate in the first film (he's still the only one in the class who doesn't make fun of or speak badly about Hiccup).
Genius Bruiser: Once he gets some confidence, he and Meatlug can do serious damage.
Genre Blind: If someone (especially a teenager who has a suspicious backstory) starts bringing up questions about how well your dragon can be in a serious battle, you'd figure he would have a few red flags raised in his head.
Gentle Giant: Films only; in the books he's just as scrawny as Hiccup.
Huge Rider, Tiny Mount: His Gronkle is far from tiny, but Fishlegs still is about a third of its size. It should be noted that, out of all of the dragon breeds encountered so far that are large enough to be ridden, the Gronkle is definitely the smallest.
Dude, Not Funny!: In-universe example. He makes a few jokes alluding to Toothless being unable to fly in "What Flies Beneath". Astrid and Hiccup were not amused.
Neither Astrid or Hiccup were amused by his mocking of Frozen Fin Hofferson.
Dumbass Hasa Point: He might be an idiotic jerk, but in the same episode above, he accurately guessed that Toothless wouldn't allow Hipccup to help him to fight off the Wispering Death because his (Toothless) grudge against such that dragon and personal pride are too strong to make him listen to reason.
Get Rich Quick Scheme: He seems to be mildly prone to these for unknown reasons. In "Gem of a Different Color" he sells lucky rocks actually changewing eggs to various villagers, even getting one woman's son in payment. In "Tunnel Vision" he responds to Berk's lack of water by trying to sell the water he and Astrid were sent to get to alleviate the problem.
Hopeless Suitor: For Astrid. Even Astrid's voice actress agrees. After the film, it switches between playing sweet and flirty teasing. Astrid nearly throws up when he suggests her to be his "queen".
In the film he's a traditional example but eases up.
According to "Thawfest" this is due to pressure from his family.
Jerk with a Heart of Gold: As in the books, he's very huff-puff about growing up to be a manly Viking, but has a definite soft spot, especially for his dragon Hookfang.
The Load: His only use comes from commanding Hookfang, which he barely has at that. It says a lot that the twins, being the Dumb Muscle of the group, are more reliable as the big guys than him due to it.
Zigzagged in "The Defiant One", where his physical strength is useful in fighting off Outcasts, but it would have been avoided if he didn't defy Hiccup's orders.
He seems to be growing slowly out of this. During the events of "Tunnel Vision", he worked with Astrid to set a trap for a Whispering Death, with her acting as bait and he and Hookfang springing the trap.
Leader Wannabe: When Hiccup is forced to put Toothless back in the cove during "The Terrible Twos", Snotlout tries to use the fact that Hiccup no longer has a dragon to take his place as leader of the Academy. Astrid quickly reminds him that she, as Hiccup's second, will be taking the position. Making it worse is that help tends ignore or argue with Hiccup, which gets them in trouble.
Made of Iron: Can take a giant rock to the face and shrug it off with a grin. He's also the most physically capable of the young Vikings, having won every Thawfest festival because of his strength and stamina.
Miles Gloriosus: He has won every Thawfest game, but in daily life Astrid and Hiccup are much more reliable.
The Resenter: "The Defiant One" reveals that a lot of his issues with Hiccup stem from jealously over Hiccup's accomplishments, especially in light of the fact that Hiccup is far from a conventional Viking. Given what we've seen of his father, and the way Snotlout was listing Hiccup's accomplishments as if they were things he'd heard over and over again, it could well be that we're hearing his father's sniping at his son for not seizing more recognition for himself.
Running Gag: Hookfang lighting his pants on fire, forcing him to leap into the nearest water source.
Vitriolic Best Buds: There are moments when you wonder if he and Hookfang aren't trying to kill each other, but Snotlout was visibly upset when it looked like Hookfang would have to be put down, and Hook does seem to genuinely care when Snotlout is in real trouble.
"Well Done, Son" Guy: In some ways he has it worse than Hiccup ever did. Stoick may have been visibly disappointed at times when Hiccup messed up, but he never threatened to withhold his parental love. Snotlout's father made this a clear threat when he was in danger of losing the Thaw Games.
Wouldn't Hit a Girl: Played with. Before punching Tuffnut, he checks to make sure he's the male twin.
Tuffnut and Ruffnut Thorston
Voiced by: T.J. Miller (Tuffnut) (Film and TV series) and Kristen Wiig (Film)/Julie Marcus (Ruffnut) (TV series)
Dumb Blondes: It would be charitable to say there's one whole brain between them.
Fearless Fools: One of Hiccup's monologues notes that someone people "don't know when to be afraid."
Half-Identical Twins: The only difference appears to be the fact that Ruffnut has braids and Tuffnut is slightly taller.
Hidden Depths: Ruffnut was able to instantly realize that Meatlug laid eggs and was a girl, before Fishlegs was able to comprehend either.
They also seem to have a love of exploring, so they tend to know quite a bit about Berk Island, including all the tunnels the Whispering Death hatchlings made. At least Ruffnut also seems to have a good memory for paths.
When stuck in a trap and left alone with Barf and Belch, Tuffnut becomes suprisingly philosophical with them.
Sibling Rivalry: Both of them are a classic case of the "bickering twins" stereotype.
Token Evil Teammates: Downplayed compared to the rest of the group. Both of them mention that their motivation for doing most things is seeing things get destroyed (typically through their dragon), conducting pranks all around Berk, or just simply getting themselves injured for no reason other than fun. When they find out the metal dragon perches they've been building are to help stop buildings collapsing from under the weight of dragons, they feel betrayed that they were coerced into helping things not break. Of course they are noble when it comes to genuinely helping others.
Took a Level in Dumbass: Ruff and Tuff weren't the brightest in the movie or the specials, but they weren't particularly stupid either. Mainly, Tuffnut was just egotistical, and no more so than Snotlout. Come the TV show, they've been downgraded into the Dumb Muscle of the team, completely missing things such as what Hiccup and Astrid are trying to convey when they say there is no Dragon Flight Club while trying to recruit them into it.
Too Kinky to Torture: Whenever someone jokes about a plan involving one of them getting seriously injured or sacrificed, the usual response is that they're happily to oblige.
Use Your Heads: They cracked nuts on each others heads while watching lightning rain down on Berk.
Vitriolic Best Buds: They're never seen apart and usually hitting each other. The behavior extends to their dragon.
Would Hit a Girl: Tuffnut. Though, to be fair, Ruffnut usually asks him to and hits back.
Gothi, the village Elder
A tiny old woman. She is a respected elder of the village who not only selects the top graduate of the Dragon Academy back when they killed them, but also is the auger of the village.
Cool Old Lady: Don't let the fact she doesn't speak fool you, she will hit you if you bad mouth her.
Demoted to Extra: According to some behind-the-scenes content, Gothi was intended to be a Mage who would've foretold of Hiccup making peace with the Dragons and the Vikings. However the writers felt it took up too much time for her to be established and that Hiccup's friendship with Toothless was a better indicator of what was to happen in the film.
Everyone Calls Her Gothi: In old Norse, Gothi is the title of a priest, not an actual name. Admittedly, it is the masculine form, but it still fits with her use of divination and general reverence from the community.
No, Except Yes: According to rumor, she can tell you when you will die by looking at your fingernails. Gobber assures Astrid and Fishlegs this is completely wrong. She looks at your tongue.
Bucket Helmet: Bucket, naturally, in contrast to his fellow Vikings. Even so, he took a mace to the head and wasn't even dazed.
Cloudcuckoolander: Bucket, as a result of a dragon-induced traumatic brain injury that "cracked his skull". He wears a Bucket Helmet and has some obvious memory and attention problems for which Mulch serves as...
Cloudcuckoolander's Minder: Mulch frequently gives the forgetful Bucket verbal prompts, and tries to find him when he wanders off.
Demoted to Extra: seen frequently in the first season, they haven't been seen at all in the second one.
Disability Superpower: "When he (Bucket) lost half his brain...he suddenly became an artist." Not just any artist either, but the best in Berk.
The Guards Must Be Crazy: Bucket is a terrible guard because he didn't call for help or even calmly look inside Heather's cell before opening it and getting knocked out.
All of the Other Reindeer: Despite his ability to sway public opinion against the dragons, Mildew is widely disliked amongst the adult Vikings; so much that they collectively decided to build his house well outside of Berk proper. When they recall surviving a blizzard, his fellow townsfolk speak of him thusly:
Bucket: It took us a week just to dig Mildew out.
Mulch: And the rest of our lives to wonder why we bothered.
Animal Nemesis: Downplayed. Mildew deeply resents the presence of the Dragons, and conspires to see them exiled from Berk. In "Dragon Flower", he poisons them..
Bestiality Is Depraved: Implied as strongly as a kids' show can - the wall of his hut contains paintings of his three wives and his pet sheep, leading Hiccup to make the obvious conclusion.
Big Bad: As close as the TV series has to a main villain. Alvin the Treacherous is a bigger threat, but not around enough to count. As of "We Are A Family, Part 2" Mildew has become the Evil Genius of the Outcasts which makes Alvin the true Big Bad.
The Bluebeard: Implied. Mildew is thrice-widowered, and the obvious, wistful joy he takes in reminiscing about his wives' funerals is both disturbing and suspicious.
Destroy the Evidence: From his years of dragon hunting he has a pair of Zippleback boots and claw of a Monstrous Nightmare. He used to frame those two for some crimes and once the dragons are gone, he tossed them into the ocean.
Evil Counterpart: to Hiccup. Both are outcasts in Berk who finally managed to find their place through dragon training. Mildew just needed to become another kind of Outcast to make it work.
Evil Genius: Of the Outcasts as of of the season finale. He teaches dragon training.
Mildew tends to this whenever he thinks he's notched a petty victory against Hiccup, though his intent is usually undermined by Hiccup's tendency to carefully consider the implications of whatever Mildew has said when trying to solve a problem.
In "Alvin and the Outcasts," Mildew makes the mistake of prematurely gloating over Hiccup's likely capture in front of the much more-direct Astrid, who simply punches Mildew's lights out before he can alert Alvin of Hiccup's whereabouts.
Evil Old Folks: He's the oldest person on the island is constantly plotting evilly against the kids.
Face-Heel Turn: He wasn't exactly on the side of Hiccup, but this still applies considering he is on the Outcasts' side at the end of season 1.
Grumpy Old Man: The ill-tempered town crank who loathes the dragons and the nuisance they pose to both his property and Berk. His status is lampshaded by Gobber in "How to Start a Dragon Academy"
Gobber: Ah, here's Mildew with the complaint o' the day.
Heroic Sacrifice: Stays behind on Outcast Island to help the group escape at the end of "We Are A Family Part 2" S ubverted because he planned on staying to teach Alvin how to tame dragons.
Irony: Berk's number one dragon hater becomes the Outcast's number one dragon trainer.
Jerkass Has a Point: When introduced, Mildew is unable to sleep for the dragons tromping about on his roof, and he finds they've decimated his crops. He's entirely correct to point out the dragons' destructive potential, and that they can't be allowed to run loose and destroy property. He also does this unintentionally, since his observations of Hiccup's failures, while calculatedly mocking, are astute enough that Hiccup inevitably uses them as a source of advice.
Karma Houdini: Every time Mildew does something that would warrant severe punishment, he is able to hide the evidence or manipulate things so that he wouldn't be directly blamed, otherwise he wouldn't be on Berk for long.
He gets away with framing the dragons and rendering the village vulnerable to attack from the Outcasts, and the only real "punishment" he suffers is the dragons earning their way back into the village. Stoick is suspicious, however, and Hiccup makes it clear he'll be watching.
Subverted beautifully for Mildew in "Dragon Flower" where it looks like he was going to get away with trying to poison and kill the dragons, but starts suffering amusing injuries one after another near the end. The only thing more appropriate would have been exile. Not only that, but he is on Stoick's bad side for his actions, who is now aware he is trying to do any act to get rid of the Dragons.
As of "When Lightning Strikes" Tuffnut and Snotlout came up with a way to get him back for turning the town on Toothless in that episode: put a stature of Thor that is essentially a giant lightning rod right outside his front door. He gets zapped right before the credits.
Lean and Mean: Mildew is notably the wiriest of all the adult Vikings, with a reputation as a sourpuss.
Motive Decay: His motive has downgraded from driving the dragons out of Berk to getting rid of Hiccup and Toothless. By the end of the first season his motives have decayed to the point that he is willing to abandon his home and side with someone who himself wants to train dragons, JUST to prove he is superior to Hiccup. His speech about outsmarting Hiccup is full of pride and glee; the previous times Hiccup has beaten him have really gotten to him).
Not-So-Harmless Villain: Started out as more of an annoyance than an actual threat, but as the series continues, he's been getting more and more heinous in his actions. He comes dangerously close to getting them banished and then tries to outright kill them with poisonous flowers. Then comes the "We Are a Family" two-parter, where he betrays Berk and tricks Hiccup into teaching him how to train dragons so he can pass the knowledge onto Alvin.
Pick on Someone Your Own Size: Even when he feels he's gotten his way, Mildew doesn't hesitate to personally antagonize the Viking teenagers, especially Hiccup.
Retired Badass: Mildew uses a large glaive decorated with several dragons' teeth as a walking staff, and his home is decorated with a painting of him delivering a Coup de Grâce to a dragon, a mounted dragon skull, several weapons and other dragon-related Battle Trophies.
The Social Expert: He displays several of these traits, most of them the very reasons he can be threatening, primarily to avoid being expelled from the Island or just antagonizing Hiccup. "When Lightning Strikes" shows he is fully capable of downright exploiting the irrationality and fear of the residents against Toothless to a frightening effect. This almost got Toothless boarded on a boat to nowhere that Stoick was unable to stop because of the panic everybody was in.
Staff of Authority: He likes waving his spear about when fear mongering or some other plan to get rid of dragons.
Villain Decay: Inverted. He becomes increasingly more dangerous as the series progresses. From getting the dragons expelled for awhile, to nearly killing them with poison, to manipulating a crowd against Hiccup and Stoick. Then he defects to the Outcasts and becomes Alvin's dragon trainer.
Villain Team-Up: Sides with the Outcasts to capture Hiccup and Toothless. Then he tricks Hiccup into teaching him how to train dragons while pretending to have been betrayed by them, allowing him to teach Alvin after he is "captured" during Hiccup's escape.
Badass: One of the few people who can fight evenly with Stoick.
Batman-Gambit: In the two part season finale, "We Are A Family" he sets one up to not only capture Hiccup but trick him into training Mildew how one bonds with dragons, so Mildew can train him in return. This relies not only on Hiccup's trusting nature but Alvin's own tendency to betray people.
He continues into Defenders, where he shows up near Berk's shores, knowing the riders would react and leave the island ready for his real ploy of planting Death Whisperer eggs.
The Beastmaster: Can tame dragons as of Part 2 of "We Are A Family" season finale. He picks a Whispering Death.
Big Bad: With his introduction, he becomes a clear and constant background threat to Berk, making various Evil Plans to take Hiccup or what he knows for his own people. As of Part 2 of "We Are A Family", Mildew is working for him so he is now the undisputed head villain of the series.
As of View to a Skrill, he has been replaced with Dagur after being on the receiving end of many biggajoules of lightning from the Skrill.
Unlike Mildew, he embraces the potential Dragons can bring (for more nefarious reasons). This is why he sends Heather to act as The Mole in order to obtain the book to learn taming and exploiting the weaknesses of the other dragons.
He is willing to listen when it is clear something is beyond his skills, like when Astrid, disguised as Heather, points out the Book only goes so far. When one of his men is nearly killed by a Deadly Nadder despite following the Book's help, he agrees to this fact. To test that, he gives it to someone else.
Later, upon seeing the Monstrous Nightmare Astrid befriended in his training area comes back for her because of the bond they formed in the brief moment, he realizes he also needs Hiccup to teach them about the bonding aspect.
In "We Are a Family, Part 2", he tries to force Hiccup to train dragons for the Outcasts, but knows better than to think Hiccup will ever cooperate. Instead, he has Mildew pretend to change his mind about defecting and then trick Hiccup into teaching him the tricks of dragon training under the guise of escaping. Once Mildew fakes capture and the others escape, he teaches Alvin and they begin taming dragons.
Evil Counterpart: To both Stoic and Hiccup. He is a wise, but evil chief who leads through fear and a firm hold on power, where Stoic doesn't abuse his power in such a fashion. To Hiccup, who wants to make peace with dragons and possibly a world where all can be friends, Alvin wants dragons to conquer and destroy his enemies. At the end of "We Are Family Part 2" it is shown the dragon he bonds with is a Whispering Death, Toothless' enemy.
Evil Plan: Force Hiccup to tell him the secrets of Dragon Training so he can take over Berk. He succeeds by tricking Hiccup into teaching Mildew, who has defected to the Outcasts.
Faux Affably Evil: Treats his heinous actions with the same air one would talk about the weather, but nonetheless clearly enjoys performing them.
Genius Bruiser: Equally clever as he is strong; look at his gambit entries for proof.
I Have Your Wife: Threatened to kill Heather's parents if she didn't do as he commanded. He also used this on Hiccup with his dragon as the hostage, though that was merely part of a larger ploy.
Knight of Cerebus: Also unlike Mildew, any episodes shown involving him are completely serious. The only thing he lacks to be a true threat is the ability to tame dragons which he learns how to do in the season 1 finale.
Names to Run Away From Really Fast: Not the Alvin part, but certainly the "Treacherous" as he clearly has little intention of honoring a promise unless he can still get something out of it.
Smarter Than You Look: He looks like some vicious thug yet he is brilliant strategist when it comes to getting what he wants.
Seems to be his favorite line to use, as Savage has commented he tells him that often if he was to fail. When Astrid disguised as Heather returns to them, he planned to have her killed.
Exploited with Mildew. While it looked like he was doing this, it was actually a Batman-Gambit learn Hiccup's dragon taming techniques by proxy. It works. Later played straight when Mildew's plan with the Whispering Death eggs failed, but Mildew managed to talk his way out.
Crying Wolf: No one believes her when she says Alvin had her parents because of her stealing the book.
Genre Savvy: While she charms the males into revealing bits and pieces of info about their dragons, she heads straight to the book when gaining intelligence on the Deadly Nadder because she knows that Astrid wouldn't divulge information. Of course Astrid expected that.
The leader of the Berserker tribe, taking control from his father Oswald the Agreeable, and, it is implied, killing him. Now, Dagur seeks war where he can find it and Berk was barely able to keep the peace.
Ax-Crazy: He's known to have done several really cruel things to some of the Vikings teens, such as locking Fishlegs in a cage for three days and using Hiccup as a knife-throwing target. This is more apparent when arrives. He later tries to behead half of the twins' Zippleback and in The Night and The Fury he is actively hunting dragons.
Badass: Fought Alvin one-on-one and held his own. While Alvin did get the upper-hand eventually, that's pretty impressive against a guy who can match Stoick.
Big Bad: As of "A View to a Skrill", he has seemingly killed Alvin and usurped control of the Outcasts.
Blood Knight: He is eager to fight and by ''eager' we mean "looking for any excuse to declare war". He brought an armada with him just in case, and claims there's fifty thousand soldiers in it. He also brought the Armada to hunt dragons on Dragon Island later on.
Broken Pedestal: Of a very strange sort with Hiccup. After "Twinsanity" where he sees Hiccup fighting "a Night Fury", he comes to see Hiccup as this awesome Viking who succeeded against something no Viking had ever before won. When they meet in "The Night and the Fury" he wants to kill a Night Fury together with Hiccup, going so far as to call Hiccup his "brother." Upon learning Hiccup had deceived him and was no longer killing dragons but training them, he goes back to hating Hiccup but on a more personal level.
The Caligula: They don't call him "Dagur the Deranged" for nothing.
Evil Counterpart: To Hiccup. They are both sons of viking chiefs, but while Hiccup is intelligent and compassionate, Dagur is dimwited and brutish. While Hiccup respects his father and seeks to earn his approval, Dagur utterly despised his father (to the point of supposedly killing him) and often insults his memory.
Considers Hiccup to be very similar to himself.
Evil Laugh: He tends to have long, slightly creepy laughs. Considering his mental state, he might be considered Laughing Mad.
Evil Plan: He thinks Berk is hiding an army of dragons; he wants to find it for a pretex of declaring war on Berk.
Expy: He is a viking version of Justin Hammer. They are the opposite to the main character, took over his father's tribe/business, and both are heavily implied to have killed their father to gain it. Oh yeah, and they are both Ax-CrazyPsychopathic Manchildren.
Fiery Redhead: Brief shots of the braid sticking out from under his helmet show he has red-ish hair.
In Love with Your Carnage: Somewhat. He mentioned to Hiccup that he couldn't stop thinking about him and how well he handled Toothless (thinking it was a wild Night Fury) and mentions how he thinks he should kill Stoick to become chief, before getting pissed when he learned the truth.
Jabba Table Manners: Subverted in that he despises people who smack their lips while eating, and threatens to remove Tuffnut's legs for doing so. The only reason he doesn't is because Tuffnut impresses him with a poem.
Jerkass: The guy is one enormous prick that also is extremely unhinged, to put it mildly.
As of The Night and The Fury, he has it now that he knows that Berk has dragons.
Self-Made Orphan: It's heavily implied that he killed his father, as he says he "retired," repeatedly refers to him in the past tense, and (most tellingly) does a mock impression of his father cowering while telling Dagur to put down the axe.
Implied no more in The Night and The Fury where he mentions 'disposing' his father and being willing to do so to Stoick so Hiccup could take control.
The previous leader of The Berserkers, and Dagur's father. In the past, he made a peace treaty with Berk that had been upheld for over fifty years. While liked by Berk, his power was respected and Berk takes steps to make it clear that they were not doing anything to threaten them. However, before the latest treaty signing, it is implied Oswald died of unspecified circumstances, and either way his son Dagur took command of the tribe.
Adaptational Badass: In the books he's a Basic Brown/Garden Dragon, one of the smallest, most common dragon species (the template for the Terrible Terrors in the movies) while in the films he's a Night Fury, a Lightning Bruiser phantom dragon nicknamed "the unholy offspring of Lightning and Death."
All Animals Are Dogs: Or more precisely cats; Toothless's look in the film was inspired by the black panther and he has several cat-like tendencies mixed with canine traits.
Arch-Enemy: With the Whispering Death in "What Flies Beneath".
Artificial Limbs: Toothless has a very complicated artificial tail fin made for him by Hiccup.
Badass: The premier example of Badass in this series, aside from Stoick.
Determinator: Nothing stops him from protecting Hiccup; not a cliff, not a chain, not other dragons.
The Dreaded: Implied to be this to (most) vikings by The Dragon Manual.
Exactly What It Says on the Tin: In the books he literally has no teeth. Eventually he grows teeth near the end of the first book (though he loses them in a fight), and he started out with none because he is a very young dragon.
Guile Hero: Toothless must've been taking lessons on this from Hiccup, as in the season one finale, he stops eating and thereby forces his captors to remove his muzzle to try to force feed him. He immediately hits them with a plasma burst and tears off his remaining restraints, then swats the guards with his tail.
Handicapped Badass: In the films, where one of his tail fins is lopped off by Hiccup early on.
Happiness In Handicap: In Gift of the Night Fury, Hiccup makes him a prosthetic tailfin that Toothless can control much like he does naturally, so he won't have to rely on Hiccup while flying. After retrieving Hiccup's helmet, which was lost at the beginning of the short, he destroys it because he prefers to have Hiccup as a mount.
In the trailer for the sequel, Hiccup has rigged up a new version which can switch between manual control and automatic so Toothless can fly solo. The latter is to accommodate Hiccup's new wingsuit, allowing him to fly alongside Toothless.
Informed Ability: In the movie, Night Furies are said to be the fastest and never miss their mark. In the series, Toothless has missed a few times and Stormfly is said to be getting closer to his speed. Toothless does have a handicap, though, and by and large every target in the film was stationary (relatively or otherwise).
Moody Mount: Sometimes he'll decide, on a whim, 'I want to barrel roll' and Hiccup will have to hold on.
Revenge Before Reason: Wouldn't even let Hiccup get on him to let him fly in "What Flies Beneath" because of his grudge with a Whispering Death, even though it meant he couldn't fly and was left at a serious disadvantage.
Ridiculously Cute Critter: Toothless is essentially a giant, winged axolotl, complete with "gills" reimagined as an expressive fleshy crest on his neck.
Shipper on Deck: The look on his face after Astrid pecked Hiccup's check in the movie.
Silent Snarker: He is the most expressive dragon, primarily due to his size-changing pupils. He takes after a certain someone.
Tsundere: Toothless likes to switch among affectionate, aloof, and hostile at the drop of a hat.
The Red Death
Adaptation Name Change: In the books known as The Green Death. Was, in the movie, a case of No Name Given, and 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 recent episodes.
Big Bad: It's the one forcing the other dragons to hunt for it, which drives them to attack the Viking village.
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.
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.
Establishing Character Moment: The first thing this draconian monstrosity does on-screen is swallow a Gronkle whole for not meeting its feed quota. It follows up that appetizer with an entire Hideous Zippleback - in one bite.
Extra Eyes: Further emphasizing its monstrous appearance in comparison to the smaller, Ugly Cute dragons.
Evil Is Bigger: This guy is the only out-and-out evil dragon and it's HUGE.
I'm a Humanitarian: Perfectly willing to eat other dragons if given the opportunity. This is implied to be one of the reasons they're doing its bidding; if they don't, or fail to bring it enough, it will eat them.
The Juggernaut: While the Red Death is chasing them, Hiccup and Toothless fly around, over and under large rocky outcroppings. The Red Death plows right through them.
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.
Demoted to Extra: Other than his introduction episode he's had only minor parts. More notable in that he is the Chief's dragon and yet we only see Toothless eating near the family table. Even if he doesn't fit inside the house (his mouth is wider than Stoick's body) you would still expect him to pop up more.
Meaningful Name: Blending 'Thor' because of Thunderdrom's legendary connection to the lightning god and 'tornado' because of its strength.
Small Name, Big Ego: Stoick recited the legend about Thunderdroms in front of it and now "it won't answer to anything else" than Thornado.
Smarter Than It Looks: His design is even more ridiculous and exagerrated than most of the other dragons, and when you see him going straight at Toothless with his mouth wide open, you expect him to suffer the same fate as one Terrible Terror in the movie. Except that he dodges Toothless' blast and immediately goes back into the water, where he can hide and pull surprise attacks on the Vikings.
In one instance, Snotlout tries to prove their bond by leaping from Hookfang, who did not notice until Toothless informed him.
Another time he did not notice Snotlout screaming due to watching a falling leaf.
Running Gag: Has a tendency to set the pants of his rider on fire. Good thing Gobber has his "iron skivies"!
Took a Level in Badass / Took a Level in Kindness: At the start of the movie, he was just as angry and Viking-hating as most dragons. In the season 1 finale he acts to defend a bound Hiccup and Toothless without any order or request from Snotlout.
Vitriolic Best Buds: Sure, he sets Snotlout's pants on fire regularly, but when Snotlout is in genuine danger, Hookfang always comes through. Snotlout himself was clearly distressed when it looked like Hookfang would have to be put down in Viking For Hire.
Acrofatic: Rather subtle in that Meatlug can keep up with the group despite her appearance and the fact the rider is Fishlegs; she is also pretty agile in combat too. Her short wings and it's hover ability also make her far more resistant against strong winds than normal dragons with large wings.
Extreme Omnivore: Gronckles can eat rocks and regurgitate them as flaming boulders. Meatlug and Fishlegs have trained so she can do this in combat by catching catapulted enemy boulders in her mouth and sending them back.
Fartillery: Can stun a whispering death that was coming at her backside.
Gentle Giant: She's about as sensitive and sweet-natured as a flying tank can get.
Took a Level in Badass / Took a Level in Kindness: At the start of the movie, she was just as angry and Viking-hating as most dragons. In the season 1 finale she acts to defend a bound Hiccup and Toothless without any order or request from Fishlegs.
Attack Its Weak Point: Astrid tries to stop Stoick from grabbing Stormfly on the nose, as a Nadder's weak point is a blind spot directly in front of it. Stormfly thinks this trope is happening and panics. That said, Stormfly allows Astrid to touch her there when she hugs her dragon in "Heather Report" part 2.
Spike Shooter: All Deadly Nadders can shoot spikes from their tail, but Stormfly does it a lot in the TV series.
Took a Level in Badass / Took a Level in Kindness: At the start of the movie, she was just as angry and Viking-hating as most dragons. In the season 1 finale she acts to defend a bound Hiccup and Toothless without any order or request from Astrid.
Expy: Of the fact that Ruffnutt and Tuffnutt are twins. Barf and Belch even mirror some of their fights.
Organ Autonomy: Ruffnutt and Tuffnutt know if they're on the wrong head. They also hug each head separately when bidding goodbye at one point.
Stuff Blowing Up: The heads together have the highest firepower of the main five.
Took a Level in Badass / Took a Level in Kindness: At the start of the movie, they were just as angry and Viking-hating as most dragons. In the season 1 finale they act to defend a bound Hiccup and Toothless without any order or request from the twins.
Undying Loyalty: Barf and Belch will try it's best to follow all of the twins commands, even if the commands contradict each other and force the dragon into a stall.
Wonder Twin Powers: Separately, the heads aren't as dangerous since the gas is merely an annoyance and the spark isn't powerful. Together, they can create huge detonations.
Academy Terrible Terrors
A group of Terrible Terrors trained by the riders on a bet made by Fishlegs and Snotlout.Hiccup's Terror, Sharpshot, a loyal little dragon trained to shoot with impressive accuracy. Astrid's Terror, a Stealth Expert. Fishlegs's Terror, Iggy, which he trained to fetch objects by cue cards. Snotlout's Terror, which he "trained" to bite things (mostly himself) and be nearly impossible to remove once it does. Ruffnut and Tuffnut's twin Terrors, Butt and Head, which they trained to run into each other.
Chekhov's Gun: All their unique skills came in handy for rescuing Meatlug from the Outcasts.
Early-Bird Cameo: Each of the Terrors uses a model that was seen around Berk before. For example, Snotlout's was the one that was knocked out by Gobber's stench.
Mythology Gag: Hiccup's Terror, Sharpshot, matches up closely with Book!Toothless as Toothless' species in the books were the source for Terrible Terrors.
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.
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 Gronkles.
Make Me Wanna Shout: The aforementioned Brown Note, disorienting dragons mid-flight while it screams. But fortunately, it does not cause sonic booms like the Thunderdrum.
More Dakka: The Screaming Death shoots fireballs like a machine gun.
In one 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.
Foreshadowing / 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.
Breath Weapon: Almost all dragon species have them, and most commonly they breath fire, which is created by expelling a flammable gas and then igniting it with sparks from a mechanism in the mouth/throat. Certain species have more unique weapons, though.
More Teeth than the Osmond Family: Dragons in general have lots of teeth. Generally, the bigger the head the more teeth it has. 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).
Unreliable Narrator: Several facts about the book are shown to be wrong, including that the Scaldron DOES have venom ("Dragon Flower"), and in regards to some dragon types it knows nothing (case in point: Night Furies).
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.
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.
The iconic Fear Class dragon, 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, the other lights it, resulting in major explosions. The gas itself is also dangerous, but only with long term exposure.
Knockout Gas: The gas emitted by the right head can be this; after all, breathing flammable gas is never a good thing.
Multiple Head Case: Inverted in that the two heads work together quite well, with one providing flammable gas, and the other a pilot light.
Limit Break: In the movie, it is stated they only have enough fuel for six shots. Meatlug and other Gronkles can be seen firing more shots during the series.
Magma Man: The Gronkle is one of the few dragons that doesn't directly produce flame. 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 rock, 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 tough and its magma attack is pretty powerful.
It can even stagger a Screaming Death simply by ramming into it and keeps coming back for more!
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.
The Deadly Nadder is the iconic Sharp Class dragon, a category of dragons distinguished by their natural arsenal of spines. Amongst the most avian-looking dragons, these vainglorious dragons spend much of their time preening themselves.
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 strong rapports with their Nadders are allowed to touch them there.
Fragile Speedster: They are capable of matching speed with a Night Fury if raised properly.
The Fighting Narcissist: Deadly Nadders are extremely vain, evidenced by the generous amounts of time spent preening themselves.
Viking Parrot: Deadly Nadders resemble crested parrots rather than the traditional lizard, with rounded beak-like heads, bright scales resembling tropical plumage, and lack of forearms.
Spike Shooter: Deadly Nadders can shoot spikes from their tail with frightful accuracy.
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 dragon, emphasizing the classification's hard hitting firepower and speed.
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 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.
Fragile Speedster / Glass Cannon: Night Furies are scary and tough like all dragons and have top speed and have a Breath Weapon strong enough to severely damage giant dragons, but compared to other dragons they lack brute strength as Toothless could not handle carrying Stoick.
Nocturnal Mooks: Their coloring and fighting approach indicates that this is invoked.
The Quiet One: They are silent compared to most other dragons. Combined this with their firepower, speed, and camoflague, they are nightmarish when the sky is dark. This one of the reasons the Vikings are downright scared of these dragons in particular because you won't hear or know their presence until the moment of attack.
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 between the 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 Gobber until it got what it wanted.
Expy: To the Timberjack, according to fans of the show.
Ring of Fire: They hunt by surrounding their prey with fire.
Seldom Seen Species: A small number of them reside in the forests outside Berk. Despite this, no-one had ever seen one prior to the series (And they have only appeared in two episodes so far).
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, it also turns it into an airborne, spinning saw blade.
Introduced: "How To Pick Your Dragon".
One of the two Tidal Class dragons known in the series, Thunderdrums are large, frog-like dragons who spend most of their time in the water.
Badass: It's able to dodge Toothless's plasma blasts, and Toothless fires several times faster than any other fire-breathing dragon. It is also said to get its power from Thor itself, but that is more of an exaggeration. It is also able to plow right through solid rock without a scratch in a manner reminiscent of the Red Death.
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.
Make Me Wanna Shout: 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.
Prehensile Tail: It uses its tail to grab Stoick and drag him under without leaving the water itself.
Introduced: "Portrait of Hiccup as a Buff Young 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.
Breath Weapon: The little ones don't seem to have it, but the Queen does.
A large Tidal Class dragon that lives almost entirely out to sea; it's unclear if it can even fly any more. Spends most of its time underwater and so is rarely a threat unless it takes a hankering to a netload of fish, or decides to get territorial around a ship.
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.
Kill It with Water: 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 believe, given how easily the attack is blocked.
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.
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.
Dark Is Evil: The scariest looking dragon seen so far has also been the nastiest, with the first one harrassing the entire village of Berk, including eating several livestock, out of a feud with Toothless and the second one ending up as the mount of Alvin the Treacherous.
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.
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.
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.
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.
Light Is Not Good: The Flightmare glows bright blue and attacks anything it feels is a threat to its food supply.
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.
