Western Animation / How to Train Your Dragon: The Hidden World

Go To
"It's you and me, bud. Always."
"With love comes loss, son. It's part of the deal. Sometimes it hurts, but, in the end, it's all worth it. There's no greater gift than love."

How to Train Your Dragon: The Hidden World is the second sequel to How to Train Your Dragon. It was written and directed by Dean DeBlois (writer and director of the first two films), and was the first film by DreamWorks Animation to be distributed by Universal.

What began as an unlikely friendship between an adolescent Viking and a fearsome Night Fury dragon has become an epic trilogy spanning their lives. In this next chapter, Hiccup and Toothless will finally discover their true destinies: the village chief as ruler of Berk alongside Astrid, and the dragon as leader of his own kind. As both ascend, the darkest threat they’ve yet faced—as well as the appearance of a female Light Fury—will test the bonds of their relationship like never before.

The film is to be followed up with a second Dragons Holiday special following the events of the film's Distant Finale titled How to Train Your Dragon: Homecoming.


Character tropes (humans & dragons) go on to the respective Character Sheets.

How to Train Your Dragon: The Hidden World contains examples of:

  • Aborted Arc:
    • Drago Bludvist's intended return in this film was scrapped halfway through production. His absence is explained by Grimmel saying that he was "defeated" a year earlier, meaning that he either gave up after his attack on Berk in the previous film or had another failed attempt shortly after.
    • It's also unclear how his Bewilderbeast managed to find its way into the Hidden World, or whether he failed at his quests without his Alpha at his command.
    • The idea of Hiccup using his father's notes to find The Hidden World is abandoned once the vikings have left Berk. While Hiccup and Astrid end up finding it anyway, it is the result of unrelated circumstances and not thanks to Hiccup's original plan.
  • Advertisement:
  • Action Prologue: The film opens with Hiccup, his friends and Valka raiding dragon trappers, apparently being a common occupation for them now.
  • Adaptation Expansion: The original quote from the book series stated that "no one" knew why the dragons were disappearing. The quote from the film's trailer starts out identical to the book ("There were dragons, when I was a boy"), but goes on to say that "only a few know" where they went. The film gives an explanation for their disappearance contrary to the book.
  • All There in the Manual: According to one of the bonus features for the home video release, the offspring of Toothless (Night Fury) and the Light Fury are known as "Night Lights."
  • Anachronic Order: The film's narrative is slightly less linear than the previous films, mainly through flashbacks to Hiccup's childhood and a flash-forward to Hiccup as a grown man for the epilogue.
  • Animal Motifs:
    • The Light Fury has behaviors very similar to a cat, in contrast to Toothless' dog-like loyalty (though he has quite a lot of feline traits as well.) This theme carries over to their hybrid offspring, which have markings similar to tuxedo kittens.
    • The Deathgrippers have features of scorpions and pincer-like claws reminescent of a praying mantis, playing on the nightmarish factor of Big Creepy-Crawlies.
    • There is also one dragon, the Crimson Goregutter, bearing a resemblance to a moose.
  • Art Evolution: According to the creators, the new animation quality they developed for this film makes How to Train Your Dragon 2 look dated. Indeed the animation here is smoother, more detailed with finer gesturing with the characters.
  • Babies Ever After: The epilogue shows Hiccup and Astrid bringing their son and daughter to see Toothless and the Light Fury, who have three hatchlings of their own.
  • Badass Beard:
    • Tuffnut wants to grow one, but since he can't, he settles for tying his braids to mimic a beard and then constantly boasting of it.
    • Hiccup grows a spectacular one for the epilogue, complete with an equally awesome Badass Cape to boot.
  • Battle Couple: Astrid and Hiccup are this as they fight together to save dragons and later defeat Grimmel.
  • Berserk Button: Tuffnut, when his "beard" was cut by one of the Warlords during the final battle, causes him to yell in rage as he chases the terrified foe off.
  • The Big Damn Kiss: Astrid and Hiccup's kiss at the end during their wedding marks the beginning of their marriage.
  • Bittersweet Ending: Though the village and the dragons are saved from Grimmel and are still thriving, until the rest of the world is ready to live in harmony with them, the dragons retreat to live in the Hidden World, and fade into myth. Years later, when both have families of their own, Hiccup and Toothless reunite.
  • Breaking Old Trends: This is the first installment in the series to not have the Book-Ends of starting with "This is Berk" as the first words spoken in the beginning and have it again near the end in a monologue about Berk, and also the first movie to not end with the words "our dragons".
  • Call-Back:
    • Hiccup makes Toothless an automatic tail fin so he can fly on his own which makes Astrid reference "Gift of the Night Fury", questioning that he made Toothless one before and he didn't want it then. Hiccup answers that Toothless didn't have a reason at that time, but he does now; he wants to follow and court the Light Fury.
    • After Hiccup and his gang bring a Crimson Goregutter on the island, it begins to play with a baby Gronckle Fishlegs is taking care of and accidentally knocks over some pole, producing Disaster Dominoes knocking over few buildings, just like at the beginning of the first movie after Hiccup shoots down Toothless.
    • The Light Fury's rescue of Hiccup is framed in exactly the same way as Toothless's rescue of Astrid in the first movie was: the human is tumbling through the air, gets caught, and then looks up to see the dragon ducking its head down to smile at them.
    • While being held prisoner by Grimmel, Ruffnut references her crush on Eret in the second movie (saying that that ship has sailed and she's over him now), and also mentions Fishlegs and Snotlout fighting over her while expressing her misgivings about both of them.
    • Hiccup kills Grimmel in a similar manner to how he tried to kill Krogan during their first encounter (i.e. untying his prosthetic leg).
    • In the epilogue Astrid rushes past Hiccup on Stormfly and looks back, silently challenging him to a race. It's the same interaction they had at the end of the second film, and Hiccup even gives his son a look as if to say: "some things never change."
  • The Cameo: Drago's Bewilderbeast appears in the hidden world for a few seconds.
  • Cape Snag: A Running Gag has the cape to Snotlout's rider suit getting snagged during missions.
  • Central Theme: The Power of Love. Toothless falls in love with the Light Fury and spends the whole movie hoping to impress her. Hiccup's love for Toothless and dragon-kind has always been a motivating factor for him. Hiccup believes that fighting to keep Toothless and the dragons is a way of expressing that love, but eventually realizes that loving him means letting him go and allows him and the dragons to leave to the safety of the Hidden World. As Hiccup's Foil, the antagonist Grimmel the Ghastly believes that Hiccup's love for them is weakness, his own desire for Toothless and the Light Fury purely selfish in nature. In the Darkest Hour, Grimmel is proven right as Hiccup bringing Toothless and the Light Fury back to New Berk leaves them (and by extension, the rest of the dragons on New Berk) vulnerable to be enslaved by the warlords. Hiccup's willingness to let go (freeing the Light Fury at the cost of his own life so that she could save Toothless) leads to the Light Fury saving him while Grimmel, who has no one, to plummet to his death.
  • Cerebus Call Back: When Hiccup makes the new automatic tail fin for Toothless, Toothless rears up on his back legs to lick at his face and pull him into a hug. Before taking the dragons away to the Hidden World, he hugs a crying Hiccup in the same way, and this time, it's the furthest thing from humorous.
  • Childhood Friend Romance: At the end of the film Hiccup and Astrid finally tie the knot after all their years as both friends and lovers. Also during the wedding Ruffnut ends up choosing Fishlegs as her love interest.
  • Commitment Issues: While Hiccup and Astrid are still dating, it is very clear that everyone is expecting the two of them to eventually marry. Both are a little apprehensive at this, Astrid especially. Notably they don't necessarily act like they don't plan to marry each other, their apprehension is more about when to do it. They eventually do get married the following winter, followed by the Babies Ever After epilogue.
  • Continuity Nod:
    • A Freeze-Frame Bonus when the Riders return to Berk shows that one of the statues at the front of the island now has a different head, because Drago's Bewilderbeast destroyed it during the invasion of Berk in the second film.
    • One of the descriptions Hiccup read of the Night Fury in the first film was "the unholy offspring of lightning and death itself...". This film shows a literal evidence for this.
    • In the second movie, Hiccup irritatedly brings up that Toothless’ saliva ‘doesn’t wash out’ when the latter licks him. Turns out it makes a very effective coloured glue/fireproof coating when mixed with crushed dragon scales for the riders’ armoured flight-suits/Toothless’ new tail.
    • Astrid once again asks Hiccup an Armor-Piercing Question she asked in the first movie; "So what are you gonna do about it?", to which he responds "Probably something stupid."
    • When Hiccup is putting the finishing touches to Toothless's new tail fin that would allow him to fly without him, Astrid acknowledges that he got rid of the first one he made, only for Hiccup to point out that he did not have a reason for it until now.
    • While trying to court the Light Fury, Toothless eventually decides to draw for her which gets her attention as he draws her face. He then growls at her when she steps at a line of his drawing. Also, as he draws a very good image of the Light Fury's face, Hiccup comments, "Oh, now you can draw?"
    • At the end of the movie, as they are going their separate ways, Hiccup touches Toothless’ snout in the exact same way he did at their first meeting.
    • In the epilogue, Hiccup introduces his and Astrid's two children to Toothless, and they greet him by touching his snout with their hands.
  • Contrasting Sequel Antagonist: While both Drago Bludvist and Grimmel the Grisly have various qualities that make them Foils and Evil Counterparts to Hiccup himself, they both have various things that contrast one from the other.
    • While Drago was a Hades Shaded Brute, Grimmel is Lean and Mean with an Undeathly Pallor.
    • While both used morally irreprehensible means of controlling dragons, Drago relies on breaking their wills and using an enslaved apex predator dragon to command them while Grimmel skips a few steps and uses venom to make them slaves to his suggestions.
    • While Drago was leader to the Warlords, the warlords in-turn hired Grimmel to help take down Hiccup.
    • Drago is the kind of guy who would throw an army and his Bewilderbeast at a problem, Grimmel is a Chessmaster, outthinking his opponents several moves ahead with the help of his comparatively smaller group of Deathgrippers.
    • Drago wanted to enslave dragon-kind so that he could later move to conquering humanity, while Grimmel is an Egomaniac Hunter that would prefer killing all dragons, starting with the Night Furies.
    • While Drago shared Hiccup's physical distinction of being an amputee, Grimmel shares Hiccup's intellectual distinction of being an inventor of cunning dragon-handling gadgets and traps.
  • Contrived Coincidence:
    • The titular hidden world is far out into the sea and has never been discovered by vikings before, yet after the Light Fury takes Toothless there, Hiccup and Astrid take Stormfly to search for him and come across the hidden world almost right away. Although, they do mention that Stormfly is tracking Toothless' scent, giving an explanation.
    • The time skip at the end of the film has Hiccup and his family traveling to find Toothless. Despite Toothless having moved to the hidden world, Hiccup finds him, the Light Fury and their hatchlings chilling on some rocks on the surface at the same time they decide to search for them.
  • Costume Evolution: Most likely due to the improvements in animation quality, the riders now wear incredibly detailed scale-patterned battle armour that is coloured and customised to resemble the appearance of their particular dragon. Like Hiccup, Astrid now has a masked helmet that features back horns to resemble her dragon, Stormfly.
  • Crafted From Animals: Hiccup and the gang all have armor made from their dragon's scales, which serves the dual purpose of giving them a resemblance to their dragons and allowing them to walk through fire.
  • Creative Closing Credits: Features a Good-Times Montage of Hiccup and Toothless together from all three movies. Later, the headings for different sections/departments in the credits are animated with 2D Vikings acting out something related to the section's title (for example, for "modeling", a short animation shows two Vikings chipping away at a block to make a statue).
  • Demoted to Extra:
    • Eret gets hit by this hard in the movie, to the point his screentime is reduced to a couple of minutes at most.
    • Berk itself could be considered this, considering it is abandoned after the first thirty minutes of the movie and it is never referenced again.
  • Disney Villain Death: Grimmel plummets to his death into the ocean below, Hiccup dislodging his prosthetic foot as the Light Fury catches him.
  • Dragon-in-Chief: Grimmel may have been brought in by what was left of Drago's army to deal with Hiccup and Toothless, but he's clearly the bigger threat.
  • Dude, Not Funny!: Gothi certainly thinks this of Snotlout after he asks Hiccup "Who died and made you Chief?". She gives him a nice whack with her staff for this idiotic comment.
  • Dude, Where's My Respect?: Hiccup gets this in two forms in the movie:
    • Despite being the Chief of Berk, riding a Night Fury that was declared an Alpha in the previous movie, saving the townspeople from certain death at least twice, and dating one of the biggest badasses in the village, Tuffnut still feels the need to give Hiccup "dating advice" and constantly points out his flaws as if he was the same clumsy boy from the beginning of the first movie.
    • While they'll praise him if they feel it's warranted, the denizens of Berk in general seem to have no problem telling Hiccup that his plans are bad, his dreams of the Hidden World half-cocked, and that his dragon is probably never coming back.
  • End of an Era: The movie's ending parallels the books in explaining why there are no more dragons.
  • Explosive Breeder: According to The Art of How To Train Your Dragon: The Hidden World, this is the reason why more and more hobgobblers keep popping up, "They're big as beach balls and have a very specific ability: they reproduce really quickly."
  • Facial Dialogue: When he and Astrid watch Toothless' coronation and mating dance with the Light Fury in the Hidden World, Hiccup's awe-turned-sadness writes itself all over his face, as he fully confronts the possibility of having to let Toothless go for good.
  • Fantastic Racism: Grimmel wants to exterminate all dragons, considering them vermin.
  • Feeling Oppressed by Their Existence: Grimmel hates Hiccup and Berk so much because he despises dragons, and views a society where humans and dragons live in harmony as a personal injustice.
  • Finishing Each Other's Sentences: At least once does Astrid finish Hiccup's sentence.
  • Flaming Sword: Hiccup still wields his flaming retractable sword, Inferno.
  • Flanderization:
    • Toothless's doglike mannerisms are much more pronounced here, and his snark and intelligence are far less prominent. Hiccup even occasionally speaks to him in a baby voice, the way people often do when speaking to their pets — something he rarely did in previous films.
    • Ruffnut's general lack of good sense and thoughtlessness has been exaggerated to the point she reveals the location of New Berk to Grimmel by mistake and she doesn't even care to control if she is followed or not while going back to the island.
  • Flashback: Stoick appears in two of them. The first is one where he shows a younger Hiccup the village of Berk from a distance and tells him the myths about the Hidden World. In the second one, young Hiccup finds Stoick grieving over Valka, and he tells Hiccup how love comes with loss, words going through Hiccup's mind as he wonders if he has to let Toothless go.
  • Female Feline, Male Mutt: Behaviorwise, Toothless has always been an amalgamation of various animals, with dog and cat featuring in more or less equal measures. The Light Fury, however, is basically all cat.
  • Flaunting Your Fleets: In the trailer, Grimmel is shown to have command over a massive armada of ships (the insignia on the ships' sails led to the assumptions that he took over Drago Bludvist's fleet following the latter's defeat in the second film). The movie reveals that the fleet isn't really his. Drago's lieutenants are in charge and are simply working with Grimmel to get their hands on the dragons.
  • Flirting Under Fire: Astrid and Hiccup do this during the final battle, during which Astrid throws a canister of Zippleback gas for which Hiccup lights up with his sword.
  • Foil: Just as Drago was a foil to Hiccup in the last film, Grimmel the Grisly is another one; he not only controls dragons using drugs (specifically venom taken from one of the dragon species he controls) but Grimmel actually copied Hiccup's feat of shooting down a Night Fury when he was a child, except that Grimmel freely killed that dragon and all other Night Furies he could find where Hiccup was inspired to bond with the dragon and became a dedicated protector of all dragons.
  • Furry Reminder: Toothless' intelligence almost makes you forget he's an animal, so he thinks like one despite being sapient. His mating dance is a very animalistic behavior to remind the audience of this.
  • Giving Them the Strip: When Hiccup and Grimmel plunge off the Light Fury, Grimmel is trying to claw his way up Hiccup's body. Hiccup undoes his prosthetic leg and Grimmel plunges to his death clinging to it.
  • Good Taming, Evil Taming: While Hiccup tames dragons with patience and a gentle hand and Drago tames them by breaking their wills and mind control, Grimmel skips a few steps and drugs them with Deathgripper venom (including the Deathgrippers themselves) to make them mentally vulnerable to his commands.
  • Good-Times Montage: Featured in the credits, showing heartwarming scenes of Hiccup and Toothless together, starting from the first movie and making its way up to this one.
  • Grand Finale: This is the final film of the How to Train Your Dragon trilogy, as well as (presumably) the franchise as a whole.
  • Greater-Scope Villain: It has been implied many times throughout the series that Toothless is the Last of His Kind. Grimmel is the man responsible for that.
  • Happily Married: Astrid and Hiccup at the end of the film, being shown ten years after their wedding with two kids.
  • Heroic Sacrifice: Hiccup tells the Light Fury to let him go and save a critically wounded Toothless instead.
  • Holding Hands: Astrid and Hiccup do this during their wedding. It is a hand-fasting, after all.
  • Hollow Earth: This is what the Hidden World turns out to be, a massive hole in the open sea surrounded by walls just short enough to allow water to flow in as a constant waterfall but not so much water as to fill the hole. The hole leads to a massive underground space large enough to be considered a world in its own right, a world lit by various bioluminescent life and crystals. It is the ancestral home of all dragons, and where the surviving dragons end up retreating when humanity proves too powerful and dangerous to survive with. The people of New Berk become the guardians of the secret of the Hidden World, hoping one day humans and dragons can live alongside each other again.
  • Hollywood Kiss: Astrid and Hiccup's kiss during their wedding is this.
  • Honey Trap: Grimmel uses the Light Fury as this. Subverted since she does not serve as the trap on her own accord and given the chance she flies away with Toothless into the Hidden World.
  • Hordes from the East: One of the warlords is Chaghatai Khan, who is implied to be Mongolian.
  • Hotter and Sexier: This film has a lot more emphasis on romance compared to the previous films and with more blatant innuendos shown. Examples include Tuffnut having his "boy talks" with Hiccup on wedded bliss. The costume designs of some of the characters (such as Hiccup's form-fitting dragon armor and Astrid's top with a lower neckline) are more suggestive than before.
    • There are two scenes where Hiccup literally gets smacked in the butt twice by Snotlout and Tuffnut respectively, and it's not subtle.
    • Then there is a moment with Hiccup and Astrid openly flirting while battling on a ship with Astrid throwing one of Hiccup's gas cylinders at some Mooks, followed by Hiccup throwing his flaming sword that causes a huge ball of fire to ignite in the background while the two gaze lovingly at each other.
  • Hypocrisy Nod:
    • When Grimmel chastises Hiccup for the love he has for dragons, Hiccup is quick to point out that he himself has dragon minions. Grimmel defies this by retorting that he had not tamed his Deathgrippers so much as drugged them with their own venom, and he would not be upset should anything happen to them.
    • While a captured Ruffnut mocks Grimmel for his "long face", she acknowledges that she also has vertical facial features before mocking his for being much longer.
  • Hypocrite: Grimmel wants to destroy Berk and kill all the dragons there, but is perfectly willing to use the Deathgrippers he's managed to train to aid in said goal. Hiccup actually points this out, but Grimmel just counters that his dragons are drugged-up slaves he has no personal attachment to.
  • I Want My Beloved to Be Happy: Hiccup comes to the platonic version of this with Toothless. When Toothless successfully woos the Light Fury and is taken to the Hidden World, Hiccup becomes restlessly worried when he does not come back. When he, Astrid and Stormfly find him, seeing that he is perfectly at home in the Hidden World with the Light Fury, he mournfully realizes that he would be happier there than he would be with him and decides to leave. He tells Toothless that he should go back when he brings them back to New Berk, and after they successfully defeat Grimmel and the warlords, Hiccup says his goodbyes to Toothless, knowing that he and the other dragons would be safer there than with him and his tribe.
  • Informed Flaw: We don't really see much of the Fury dragons' apparent aversion to the cold. At the altitudes Toothless and the Light Fury are seen flying, temperatures would be very low especially when surrounded by clouds.
  • Interspecies Romance: Word of God is the Light Fury is not actually a Night Fury, just a similar related species. This doesn't stop Toothless from courting her. Several other Light Furies are shown in the Hidden World, so she's definitely not the Last of Her Kind, unlike Toothless.
  • Last Minute Hookup: After having spent the previous film being pursued by both Fishlegs and Snotlout, Ruffnut finally settles on Fishlegs during Hiccup and Astrid's wedding, claiming she likes sensitive guys.
  • Let Us Never Speak of This Again: At one point, the Light Fury gleefully knocks Hiccup off of Toothless, who then swoops down to save him. When next we see Hiccup:
    Hiccup: (as his companions snicker in the background) Not a word.
  • Living Emotional Crutch: Hiccup admits that without Toothless, he feels like The Millstone that he was before he met him. The big lesson he learns is how to stand tall without Toothless and to let his dragon make his own life.
  • Mating Dance: The Light Fury initiates one with Toothless, who makes a complete mess of himself. They eventually meet in the middle and combine both their courtship approaches into an exchange of prancing and gurgling.
  • Miming the Cues: Hiccup mimes a few courting methods to Toothless so the latter can keep up with the Light Fury and impress her, and ultimately not to shake a branch she's hanging from. The results are... mixed.
  • Mirrored Confrontation Shot: The poster shows Toothless and the Light Fury confronting each other.
  • Mook Horror Show: Drastically averted by Hiccup at the beginning as he tried to convince a poor mook that he is not a demon.
  • Mythology Gag: In the epilogue where Hiccup and Astrid bring their children to the Hidden World, the conclusion to the story he's telling them is taken word-for-word from the start of the original book.
    Hiccup: There were dragons, when I was a boy. There were great, grim sky dragons that nested on the cliff-tops like gigantic, scary birds. Little brown, scuttly dragons that hunted down the mice and rats in organised packs. Preposterously huge sea dragons that were twenty times as big as the big blue whale.
  • My God, What Have I Done?: Hiccup's clearly feeling some shades of this during and shortly after landing from the flight from the Hidden World. It's not just the fact that he found out the Hidden World is not a viable option for Berk or any of its humans... but the flashback with Stoick also makes it clear how much he values love and relationships... and he just forced Toothless to get him out of a very dangerous spot, separating the dragon from the one he loves. He does brighten up though when he realizes the Light Fury followed them home.
  • The Napoleon: When Snotlout is trying to intimidate Eret, he steps onto a crate and then on a barrel just to reach his height.
  • Nice Job Breaking It, Hero!: Grimmel heard Ruffnut babble about the tribe's new island settlement and followed her back to the island after she escaped. When she got back to the island, she hasn't realized she told Grimmel about where Hiccup, Astrid and the Berkians are before she left. Hiccup asked Ruffnut, then finds out she was followed by Grimmel and his armada to the island, jeopardizing the Berkians and dragons' safety. Even the tone of voice she does when answering to Hiccup if she was followed ALMOST sounded like if she betrayed her own friends, but never did.
    Hiccup: (cautious) Ruffnut, focus. Were you followed?
    Ruffnut: I never look back, Hiccup.
  • No Name Given: To emphasize the Light Fury's wild nature, the crew deliberately avoided giving her a name.
  • No-Sell: Hiccup and the gang now wear fireproof armor made from dragon scales, which leads to them being mistaken for demons due to them being able to walk through fire. Later, Toothless' autonomous prosthetic fin gets the same treatment.
  • Official Kiss: Astrid and Hiccup's kiss during the wedding is this as it marks the beginning of married life for them.
  • Off-into-the-Distance Ending: Much like the first movie, The Hidden World ends with Hiccup and Toothless flying off into the sky. This time, however, they are joined by their respective significant others and offspring (and also Stormfly).
  • Out of the Inferno: Hiccup and Toothless walk through a blazing fire side-by-side with no signs of flinching.
  • Pale Females, Dark Males: The Light Fury is white, whereas Toothless is black. Averted with the Light Fury species as a whole; we see a few standing around and they're all as white as one another.
  • Patchwork Kids: Two sets:
    • Hiccup and Astrid's kids: The girl looks very much like her mother, but with her father's hair color, and vice versa for the boy. He in particular looks so much like his father in the flashbacks that the same model was probably used for both characters.
    • Toothless and the Light Fury's hatchlings: All of them share the primary scale and eye color of one parent, but with spots of the other parent's color.
  • Pin-Pulling Teeth: Astrid does this with one of Hiccup's dragon gas grenades on board of Grimmel's ship.
  • Pity the Kidnapper: Invoked by Ruffnut as she annoys Grimmel with her incessant talking (including her annoying twin brother, her love life, and her hair braids) until he snaps, releases her, gives her a dragon fledgling to ride and tells her to just get out. Tuffnut even says he feels sorry for the kidnappers who got stuck with her. Unfortunately, she's not nearly as clever as she thinks; Grimmel also heard her babbling about the tribe's new island base and had her followed back to them.
  • Posthumous Character: After being killed in the second film, Stoick appears through flashbacks to Hiccup's childhood.
  • Precision F-Strike: Gobber at one point says "bloody hobgobblers".
  • Properly Paranoid: The Light Fury is deeply distrusting of humans, and will either attack or flee if she spots one. Considering her introduction to the plot involves being captured by trappers, given to Grimmel, drugged, and left in a clearing for Toothless to find, this is a very fair and reasonable reaction.
  • Reality Ensues:
    • It's mentioned that Berk has become seriously overcrowded due to the excess amount of dragons that Hiccup has brought in.
    • Gobber also points out that Hiccup can't just go off on adventures like he used to and has a responsibility to watch over Berk as chief.
    • Dragons are not domesticated animals and have been living with humans only a few years so, as beautiful as Hiccup and Toothless's friendship is, once a suitable mate appears, Toothless's instincts take over and he starts prioritizing courting the Light Fury over almost anything else.
    • Drago Bludvist's army is a driving force in the film and still significantly large in number. The army is now commanded by several Warlords. Just because their leader is gone, doesn't mean there aren't other people with authority who wanted the same goal.
  • Ruling Couple: With Hiccup being Chief of Berk, Astrid and Hiccup become this when they get married near the end of the film
    • Implied Toothless, still an alpha dragon, and the Light Fury are this for the Hidden World.
  • Sadistic Choice: Grimmel seems to have a habit for this:
    • First, he proposes to Hiccup to either give up Toothless, or he will raze Berk. Hiccup tries to Take a Third Option and moves his village away, which would have worked if not for botched kidnapping mission (although it's made clear that Grimmel knows the direction they went, so he would have found them eventually anyways).
    • Later, he also forces a bound Toothless to choose between his flock of dragons or the Light Fury's life. He chooses the Light Fury.
  • Scary Impractical Armor: While this is generally averted in that most of the riders now have flight suits that are quite practical and protect them from fire and make them look intimidating while on missions, Snotlout’s is the only one that is made more useless by it. His Badass Cape repeatedly snags whenever he tries to make a Three-Point Landing and his helmet done in Hookfang's likeness has a bad habit of being knocked at an angle, leaving him blind during fights.
  • Secret Keeper: It's quite possible that Hiccup and Astrid never told any of their companions where the Hidden World was. They are the only ones that return to its entrance years later with their children.
  • Shock and Awe: While flying with the Light Fury and trying to mimic her disappearance trick, Toothless finds out he can summon lightning to his body a la the Skrill, and temporarily become invisible that way.
  • Shown Their Work:
  • Silence Is Golden: Several sequences, like Toothless trying to woo the Light Fury and their flight together afterwards, play out with little to no dialogue.
  • Smoke Out: The Light Fury is able make herself temporarily invisible by flying through the explosion of her plasma blast.
  • So Much for Stealth: Hiccup's mission in the opening was supposed to be a stealth mission, but the others end up messing things up. Lampshaded by Astrid.
    Astrid: I thought this was supposed to be a stealth mission?
    Hiccup: Yeah, they always start that way.
  • Strong Family Resemblance: Hiccup and Astrid's kids look a lot like the parent of the same gender; the boy in particular is his father's splitting image but with blond hair.
  • Tag Line: The Friendship of a Lifetime. The Epic Conclusion.
  • Talking the Monster to Death: Ruffnut ends up getting left behind when the riders escape from Grimmel's tower. What follows is a scene where Ruffnut talks non-stop, either insulting her captors or goes on wild tangents about her personal life. It annoys Grimmel so much that he lets her out and demands that she leaves, even providing her a dragon to ride on. Granted they end up following her, but it is still hilarious.
  • That Came Out Wrong:
    Snotlout: (to Hiccup) Who died and made you chief?
  • The World Is Not Ready: In the end, the dragons retreat to the Hidden World until the rest of humanity is ready to live in harmony with them.
  • They Do: Hiccup and Astrid marry near the end of the film.
  • Throwing Your Sword Always Works: Hiccup tosses Inferno at a group of leaking barrels containing Zippleback gas, causing them to explode and set fire to the ship they're on.
  • Time Skip:
    • Downplayed with the main narrative. Unlike the five year gap between the first two films (which was bridged by the television series), The Hidden World takes place only one year after the second film, with Hiccup still struggling to cope with being chief after Stoick's death.
    • The epilogue takes place nine years after the main narrative, with a now married, 30 year-old Astrid and Hiccup bringing their two young children to meet Toothless.
  • Trailers Always Spoil:
    • The trailer shows the Light Fury saving Toothless, though that wouldn't surprise anyone, and Toothless flying without his saddle, but with a new tail prosthetic.
    • The second trailer revealed that Drago's Bewilderbeast would return in the film, though it's only for a cameo.
    • The above trailer and a December 2018 ad for the film shows brief clips of an emotional scene where Hiccup pets and holds Toothless while he's crying, strongly suggesting it may be the scene where they say goodbye.
    • Between the trailers, TV spots, and preview pages of the books, it's possible to get a very solid picture of how the movie ends. Word of God didn't exactly help either, outright confirming in interviews long before the movie's release that the dragons were going to leave.
  • Unflinching Walk: Hiccup and Toothless at the very beginning of the movie, strolling through the flames of a burning enemy ship, with Hiccup brandishing Inferno.
  • We Work Well Together: Valka acknowledges in the beginning that while the riders are impressive on their own or with their dragons, they lack any real chemistry when it comes to teamwork. They eventually get the hang of working together during the fight against the Warlord's armada. Hiccup and Astrid even get a Battle Couple moment.
  • You Are Better Than You Think You Are: One of the Central Theme of the film. Hiccup and his friends have become too dependent on their dragons, so when they face an Outside-Context Problem that dragons cannot or not available to solve, they became less competent. The crux of the film is Hiccup and friends learning to stand on their own, which allows them to deal with parting ways with their dragons so they can go live in peace in the Hidden World.
