"Such is the life of an adventurer."

A blue-haired, adventure-loving girl who fears nothing and enjoys exploring the wonderful, supernatural world around her even in the face of danger.

---

• Action Girl: Hilda is someone who isn't afraid to leap into the thick of things and prefers to pick up a sword to fight her problems head on. However this attitude also doesn't make her a good candidate for a witch, that focuses on applying knowledge and deductive reasoning.
• Adaptational Nice Girl: Hilda is more of a Bratty Half-Pint in the comics, being easily annoyed when things don't go her way, and less considerate of her mother's worries. She's not a bad person deep down, though. While she still has her questionable moments, the show's portrayal of Hilda is much nicer, and a saint compared to her comic counterpart. The novelization tie-ins bring her more negative traits back, and even cranks them up a little; Alfur notably called her a big bully in "Hilda and the Hidden People". However, in Season 2, Hilda acts more ornery, especially towards her mum.
• Aesop Amnesia: In "The Fifty Year Night", Hilda learned a lesson about the consequences of one's actions, and respecting her Mother's wishes. However, the ending of the same episode also saw Hilda tell her mother a lie by omission about sneaking out, implying the lesson didn't fully stick. In "The Stone Forest", Hilda once again gets into an argument with her Mother, and decides to sneak out. This leads to the events of the aforementioned episode, but in the end they make up more properly. This is explicitly lampshaded in the song "The Life of Hilda", as it begins with "My name is Hilda/I don't learn from my mistakes."
• All-Loving Heroine: Hilda is a good-natured young girl who does all that she can to help those in need. Be it her mother Johanna, her friends David and Frida, and any mystical creature that Hilda befriends, she will do anything to help them.
• And Then John Was a Zombie: Season two ends with Hilda transformed into a troll.
• Animation Anatomy Aging: After the Time Skip at the end of "Hilda and the Mountain King", Hilda is now a preteen or young teenager and is about a head taller.
• Artsy Beret: Wears a black beret as part of her usual attire, and she likes to draw the fantastical creatures around her.
• Bait-and-Switch: Season 1 sets up the possibility that Hilda might become a witch, but Season 2 revealed that Hilda doesn't have the right temperament to become one, and she instead becomes Frida's familiar.
• Be Careful What You Wish For:
  • In "The Tide Mice", Hilda uses a spell to make sure that David and her mother achieve their goals. However, she never read the whole thing, and ends up finding out that the Tide Mice are actually part of a spell to steal the souls of the people they grant the wishes of.
  • In the Season 2 finale, Hilda has a bad argument with her mom that makes her wish she was a troll so she could live free in the wilds. She is turned into one against her will by the end of the episode.
• Blue Is Heroic: She has blue hair, and is the hero of the show.
• Bold Explorer: Insatiably intrepid.
• Brains and Brawn: Hilda is the brawn to Frida's brains. This is the reason why Hilda was not qualified to be a witch due to her taking action first over thinking things through.
• Break the Cutie: Hilda lets it out when she has to let Twig go. He comes back eventually.
• Broken Pedestal: Let's just say the admiration she had for Victoria Van Gale goes out the window once she sees her darker colors.
• Brutal Honesty: She doesn't mince words when she tells her classmates and teacher that the "Troll Protocol" they practice would do no good in an actual troll attack.
• Character Check: As noted in Adaptational Nice Guy, Hilda in season one is nicer than her comic counterpart, who was a mouthy brat. Season two fixes this by having her take a few levels in jerkass, becoming more aggressive and treating her mother like a nuisance at certain points.
• Character Development:
  • She starts out as a mostly agreeable if single-minded girl who just wants to live an isolated life in the wilderness adventuring. She later realizes the need for her to move to Trolberg, both for the good of her and her mum and for the sake of magical creatures like the elves. Although reluctant at first, she comes to see Trolberg as a home as well.
  • In season 2, she reveals a more ornery side when she doesn't get what she wants. She starts to lie to her mother to keep her independence, and lashes out when she's caught and grounded. However, she also shows angst about whether or not she's a bad girl, and will eventually try to patch things up with her mother whenever it goes sour.
• Characterization Marches On: In the first two episodes, she makes a big deal about having a sketchbook and drawing magical figures, but she doesn't do anything of the sort once she moves to Trolberg and it's not mentioned again till Chapter 13, where she uses her sketchbook to make a quick drawing of Tontu. This despite finding many creatures to draw in Trolberg.
• Child of Two Worlds: Though not literally (probably), Hilda feels torn between the world of humans and the supernatural.
  • The finale reveals that Hilda is part-fairy; while her father is a regular human, her grandfather is indeed from another world.
• Chronic Hero Syndrome: Hilda loves trying to help people and will go to great lengths to do so. The downside to this though is Hilda often gets into situations well over her head and has a very hard time asking for help herself.
• Constantly Curious: She is always curious about the magical world around her, sometimes to her own detriment.
• Cool Big Sis: It's somewhat implied that after the Trolls and humans made peace with each other, that Hilda started treating Baba as a surrogate younger sister.
• Country Mouse: While very plucky and social, she still loved growing up in the wilderness and has trouble adapting to city life.
• Cute Monster Girl: Despite being turned into a Troll, Hilda still resembles the adorable young adventurer we all know.
• Deal with the Devil: Upon meeting Trundle, Hilda makes a pact with him that if she completes three tasks, Trundle will turn her back into a human. Unfortunately, this was all a ruse so that Trundle would be released from his prison.
• Determinator: Throughout the series, Hilda is shown to do whatever it takes to accomplish something. Whether it's helping a giant find his lost love, to helping a talking bird regain his memory.
• Didn't Think This Through: Tends to leap before she looks. Especially in "The Tide Mice," where she casts a spell to help David and her mum with their ambitions without reading the footnote, side effects, or means to break the spell.
• Disappeared Dad: Her father is never seen or mentioned, and it's outright stated in episode 11 that her mother is single. Luke Pearson confirms her father is still around, but doesn't live with them. Note that she asks Trylla, her then adopted troll mother, if she has a "troll dad" and looks downcast.
  • Her father finally turns up in the third season.
• Ditzy Genius: While she is highly intelligent, she also tends to be socially-awkward and impulsive.
• Digging Yourself Deeper: She finds herself doing this during the season two mid-point, since rather than come clean about what she was doing, even if her mother would get worried, she tries to uphold to lie, causing Johanna to ground her.
• Don't Tell Mama: If her Mum doesn't find out Hilda's going on an adventure, she always tries to make sure she stays in the dark, mostly to stop her from worrying for her. This gets Deconstructed in the middle of season two, when Johanna finally grows sick of being Locked Out of the Loop regarding Hilda's adventures and grounds her as a result.
• Don't You Dare Pity Me!: At the end of "The Deerfox", after Hilda had to let Twig go off with his family, she starts to lament that her old house was gone, having to leave the wilderness, and never getting to see her pet deerfox again, Johanna tried to comfort her daughter, but Hilda shrugged her off and begins to breakdown in tears. Luckily, Twig decided to stay with Hilda.
• Empowered Badass Normal: Downplayed. After the events of "Hilda and the Mountain King," she's gained the ability to speak to trolls, and its implied she's retained some measure of physical strength and agility.
• Establishing Character Moment: Hilda finds a troll rock and hangs a bell on its nose for safety, then sketches it until nightfall, at which point it comes to life and chases her back to her house. Once she realizes the troll is only trying to get the bell off, she gently unties it and gets her sketchbook back as thanks. We can already tell that Hilda is a smart, resourceful girl with a deep understanding and respect for the supernatural creatures around her, with a curiosity and overconfidence in her own abilities that can sometimes get her into trouble.
• Evil Costume Switch: Well, not evil, but more like Jerkass. In the Stone Forest episode, she has switched out her beret, scarf, and skirt in favor of a ponytail, a turtleneck, and pants. By this point, her relationship with her mother has been strained, and she acts more snappish and rude towards her.
• Failed a Spot Check: At the end of "The Tide Mice", after Hilda undid the spell to free David and her Mom from having their souls taken, she forgot to feed the Tide Mice a piece of bread. This would come to bite her in "The Jorts Incident" where the Tide Mice placed themselves on top of a random delivery man, then overtaking the Jorts factory. Thus, Hilda and her friends had to capture all of the Tide Mice before all of the factory employees get their souls taken.
• False Flag Operation: Hilda holds Erik Ahlberg in a low enough regard for being an extreme gloryhound that she wouldn't put it past him to having faked the monster attacks in episode "The Beast of Cauldron Island".
• Fatal Flaw:
  • Overconfidence. She's genuinely brave, clever, and talented, but she often gets herself in unnecessary trouble due to her belief that she can handle anything. Aside from her Establishing Character Moment, this bites her in the butt hard (and almost costs her friendship with Frida) in "The Ghost," where she insists she can fulfill her promise to Frida to fix the situation of her bedroom despite increasing evidence that even her best abilities might not be enough in this situation. She also has a hard time not only accepting she needs help, but also asking for it: from the thunderbird incident, to "The Ghost" mentioned above, she'd be able to deal with her problems more easily if she swallowed her pride and asked for a hand.
  • Independence. She dislikes rules and restrictions, and initially doesn't think she needs other human friends. In Season 2 she starts to lie to her mother so that she can do what she wants, and when she's caught and grounded, she chalks it up to her mother doing "what parents are supposed to do."
  • Trusting others. Overall, Hilda is a very trusting person, and is willing to trust those whom she only just met. But there are those who would take advantage of Hilda's trust for their own purposes. One example is when Trundle tricked Hilda into releasing him from his prison by pretending to be a friend in need and promising that he will turn her back into a human. Hilda was not happy when Trundle betrayed her.
• Fish out of Water: She is not exactly at home in Trolberg, thinking that all streets and houses look the same. It takes her a while to adapt to it.
• Forced Transformation:
  • Is turned into a troll against her will at the end of the season two finale.
  • Before that, she's given a slap-on-the-wrist punishment for her having caused the tide mice incidents: she's forced to have mouse whiskers until the day is over (she's doesn't even see it as a punishment, but seems to find them cute).
• Friendless Background: It's not given much attention, but since she spent most of her time on the wilderness, the only real friends she really had were her Mum and Twig. In fact, the first thing her Mum has her do once they've moved to Trolberg is try to make some friends.
• Friend to All Living Things: She easily makes friends because of her caring heart. There really doesn't seem to be a creature alive that she can't befriend, except the Marra.
• Future Me Scares Me: During the climax of "The Fifty Year Night", Hilda meets a future version of herself who was trying to warn her about something. But Future Hilda kept on berating Present Hilda for "Messing with time", and not giving her direct answers. Naturally, Hilda felt uneasy interacting with her future self.
• Girlish Pigtails: Chapter 9 of Season 2 shows that she used to wear her hair in pigtails when she was younger.
• Going to Give It More Energy: In season 2, when she can't stop Erik's automated bell-ringing system from happening, she instead turns up the volume loud enough that the central tower's bell gets thrown clear out of the tower.
• Going Native: Downplayed. After spending a few days in Troll society, Hilda starts to enjoy the perks of being a Troll. Such as the enhanced strength and the ability to roar. However, Hilda still longs to be human again, and to return home to her mother and friends.
• Heroic BSoD:
  • In "The Storm", she's shown having fallen into one after her falling out with Frida. She snaps out of it once said episode's plot gets going, though.
  • In "The Mountain King" movie, After Hilda sees her reflection as a Troll, she is horrified and begins to cry. Until Trundle comforts her and tells her that he knows a way to change her back into a human.
  • When Trylla told Hilda that she has no idea how to reverse the changeling spell, Hilda did not take it very well.
• Heroes Prefer Swords: Picks up a sword to fight against a monster during her trip with Frida and Kaisa, and she even tries to bring it along before Kaisa shoots down the idea. Later episodes however show the sword in Hilda's room, implying she managed to keep it anyway.
• I Don't Know Mortal Kombat: Despite being a great adventurer, who has lived most of her life in the forest, she cannot get any badges during her first year as a Sparrow Scout.
• Interspecies Friendship: Has more of these than human friendships, basically: Twig, Alfur, the Thunderbird, Tontu, the list goes on and on.
• It's All My Fault:
  • Hilda has a tendency to blame herself for incidents that she may have had a hand in causing. Such as in "The Jorts Incident", where Hilda feels responsible for the Tide Mice nearly taking over the Jorts factory.
  • In "The Mountain King" movie, Hilda blames herself for freeing Trundle from his prison.
• Jerkass Ball: Grabs a slight one during the second season, where she begins treating her mother as more of a hindrance to her adventures. This exacerbates when she lies to her, causing her mother to take more issue with her acting independently and ground her. Hilda rudely lashes out in turn.
• Jerkass Realization: After seeing her mom well-nigh breakdown in tears during their adventure in the Stone Forest, Hilda realizes how much grief she's been giving her.
• Laser-Guided Karma: Whenever Hilda goes on an adventure and her mother doesn't find out about it, she prefers to keep her in the dark rather than tell her the truth. This comes back to bite her in the season two mid-point, as Johanna grounds her for her inability to be honest with her for once.
• Morphic Resonance: Once Hilda was transformed into a Troll, she still somewhat resembles her normal self, but with grey, stone-like skin, bigger feet, a longer nose, and Troll teeth.
• Nature Lover: She loves life in the wilderness, and doesn't want to live in Trolberg at first precisely because it's more urban look is the exact opposite of what she's used to.
• Never Bareheaded: She usually has some type of hat on during the day, normally her beret.
• Nice Girl: She is sweet and amiable; if she sees someone in need of help nothing is going to stop her. That said, she's got her own rough spots.
• No Good Deed Goes Unpunished: At the end of "The Beast of Cauldron Island", after Hilda managed to prove the Lindworms's innocence, and reuniting the baby Krakens with their mother, her mother found out that she lied to her about where she was. This leads to Hilda's mother having no choice but to punish her.
• Not Afraid to Die: Zigzagged. In the first comic, after she gets lost in the woods, she's more upset over the possibly of dying without anyone know how it happened than actually dying, but she showed more fear towards the idea of dying when dealing with her other near-death-experiences.
  Hilda: There's no point in dying if no one knows how it happened.
• Not Quite Back to Normal: While Hilda is restored to her human form after a few nights as a troll, she retains an understanding of their language.
• Plucky Girl: Very much so!
• Poor Communication Kills: Hilda has a really bad habit of doing what she feels she needs or wants to do, without really explaining herself well or justifying it beyond her curiosity or doing good things. The result is often charging into problems without her friends knowing ahead of time, getting into danger while her mother is either oblivious or clearly aware of the threat but not Hilda's involvement, and more than a few characters get worried about a literal child wandering into trouble. Season 2 hits the point that she prefers to lie to her mother about her adventures, which only gets her into more trouble with a deeply-concerned Johanna, getting grounded over it; while Johanna hadn't let her say her piece on the matter, Hilda straight up took the worst ways possible to try to justify it.
• Primary-Color Champion: She's the heroine of the series, and her casual look has all three primary colors in its palette: a red sweater, a yellow scarf, and blue skirt.
• Puppy-Dog Eyes: What she uses to try and talk her mum out of moving. She even pulls Twig up to her cheek for bonus cuteness!
• Red Is Heroic: She wears red, and is the hero of the series.
• Sacrificed Basic Skill for Awesome Training: Hilda can ride a Woff, but not a bicycle. One could also argue that her ability to deal with the supernatural came at the expense of people skills.
• School Is for Losers: Kind of. Much like a lot of real-world children who take up an interest thinking they can immediately do all sorts of cool things, once Hilda finds out how much studying and schoolwork it takes to become a witch her interest in being one falls like a rock.
• Screw the Rules, I'm Doing What's Right!: She will do the right thing and help whoever is in need, regardless of what anyone else thinks. Her insistence on helping Tontu in spite of her mother's wishes ultimately ends up solving the conflict caused in "The Black Hound". Prior to that, in "The Storm" her insistence on aiding Victoria Van Gale despite Johanna's orders for her to stay indoors ends up saving the entire city.
  • This would be deconstructed in season 2 where Hilda's desire to do good lands her in trouble. At the end of "The Beast of Cauldron Island", after Hilda proved the Lindworm's innocence and reuniting the baby krakens with their mother, Johanna found out that Hilda lied to her about where she was. This leads to Johanna having no choice but to punish her. In "The Fifty Year Night" after Hilda convinced the young Mr. Ostenfeld to go after his lost love (later revealed to be Tildy), this unfortunatley caused the Time Worm to appear and proceeds to devour all of the Mr. Ostenfelds, and Hilda as well.
• Shy Blue-Haired Girl: Was initially like this when she first came to Trolberg and tried meeting new children her age. It also makes her stand out since she's the only human character in the series with abnormal hair color. There’s a reason for that.
• Signature Headgear: Her beret, and her winter hat.
• Socially Awkward Hero: Is confused about how exactly to interact with kids her own age when she first moves to Trolberg, since she and her mother spent most of their lives living alone in the wilderness. She gets better with time, though.
• Supporting Protagonist: Thoughout most of Season 3, while Hilda is still the main character, the season's overarching story is mainly centered around her mother Johanna rediscovering her past.
• Tomboyish Ponytail: Wears her hair like this while still living in the wilderness, and sometimes dons it like this when she's not letting it down.
• Tomboyness Upgrade: Downplayed with her Time Skip design in The Mountain King's epilogue and season 3. While she looks identical to her pre-time skip self, she ditches the blue skirt from the first two seasons in favor of only wearing black pants.
• Touched by Vorlons: After her time as a troll, Hilda retains the ability to speak to and understand them. The ending of the movie also hints she retains some of the enhanced strength and endurance, though significantly reduced from troll standards.
• Trademark Favorite Food: Hilda is shown to like eating cucumber sandwiches.
• Trauma Button: Her experience as a troll gave her a strong aversion towards bells. She admits that even the mere sight of them makes her feel very anxious.
• True Blue Femininity: In addition to wearing blue in her ensemble, Hilda also sports blue hair.
• Uneven Hybrid: Season 3 reveals that Hilda is ¼ fairy and inherited her blue hair from her grandfather. Naturally, she's overjoyed to discover this.
• Unwitting Pawn: Hilda was this to Trundle.
• Waking Up Elsewhere: At the end of "The Stone Forest", Hilda wakes up to realize that she had been brought back to the titular forest. This is also where Hilda discovers that she was turned into a Troll.
• Weirdness Magnet: Frida and David both mention that before Hilda showed up they never had adventures like they do now, whether that's a good or bad thing depends on how they are feeling. Some of this can be chalked up to Hilda's constant need to explore and help people, but heck the girl can't even be grounded inside her own house without nearly breaking the very fabric of reality. It's to the point when Erik Ahlberg learns that Hilda is involved in the incident with the Draugen's Ghost Ship and has been turned into a troll he remarks that he is not surprised by either. Even when she tries to do something normal for once in "The Laughing Merman", she and her friends end up getting sucked into an adventure anyway thanks to Eugene and Louise.
• Why Did It Have to Be Snakes?:
  • Scared of bicycles because she never learned to ride them.
  • Bells, because she experienced what they do to trolls first-hand. Even long after returning to normal, she admits to feeling anxious whenever she sees or hears one.
• You Are Grounded!: Once her Mum discovers she lied to her for the umptenth time, Hilda gets grounded until new notice.

Twig

Hilda's loyal deerfox companion.

---

• Action Pet: He'll spring to Hilda's protection when she is in danger, whether the threat is an eagle, a wolf, or even a troll.
• All Animals Are Dogs: Acts much more like a dog than a deer. Justified because dogs and foxes are both canines.
• Androcles' Lion: A flashback reveals that Hilda first met Twig when she rescued him while he was trapped under a pile of rocks. He repaid the favor by saving her from falling off a cliff, sacrificing his chance at being with the rest of his kind.
• Animal Companion: He is Hilda's best friend and fierce protector.
• Badass Adorable: He may be cute, but he can make good use of his teeth and antlers when he needs to. "The Deerfox" reminds viewers that he is a predator^note Hilda's Book of Beasts and Spirits does confirm his species can also subsist on plants though, as he tries to hunt a rabbit when he goes hungry in the woods (though it manages to escape).
• Black Bead Eyes: He's drawn with these.
• Cowardly Lion: He's suitably wary of dangerous creatures most of the time, but he becomes fearless when Hilda is threatened, willing to attack opponents orders of magnitude larger than him.
• Cunning Like a Fox: Is part fox.
• Evil-Detecting Dog: A few times, like with the Marra.
• Heroic Dog: He's part fox (a canine like dogs) and a loyal friend and protector to Hilda.
• I Choose to Stay: He has a chance to return to his parents in the alternate dimension deerfoxes come from, but decides to stay with Hilda instead.
• The Marvelous Deer: He's part deer.
• Mix-and-Match Critters: He is a cross between a deer and a fox, making him a deerfox.
• Ridiculously Cute Critter: Just look at him! The Wood Man gets him to wear a little scarf in "The Draugen", for no reason other than it being adorable.
• Spanner in the Works: Had Twig decided not to leave his family to save Hilda from falling to her doom all those years ago, then everything that happened in the series would never have happened.
• Silent Snarker: Even Twig is not above expressing himself towards some of the more ludicrous situations around him.
• Sudden Anatomy: He usually is not drawn with a mouth, but it will show up when he opens it or bares his teeth.
• Team Pet: Of the main cast.
• Undying Loyalty: Towards Hilda. According to Hilda's Book of Beasts and Spirits, this is actually standard for his species, with many famous figures in history having deerfox companions.
• Unusual Pets for Unusual People: Twig is a rare creature within the show, and Frida reacts with amazement when she sees him for the first time. As such, he's a perfect pet for a wilderness native like Hilda. In fact, "The Deerfox" reveals that no one knows much about his species.
• Unusually Uninteresting Sight: Supposedly, Deerfoxes are extremely rare, to the point that some people even doubt they exist, yet the amount of times that somebody reacts surprised to see Twig can be counted on one hand.

Johanna

Voiced by: Daisy Haggard, Sanchia McCormack (audiobooks)

Hilda's doting single mother, who works as a graphic artist. She cares greatly about her daughter, but tends to worry about her due to her tendency to get herself into danger.

---

• Action Survivor: She lacks the experience her daughter has in dealing with the supernatural, but she's still able to hold her own. Notably, despite being a non-combatant, she's instrumental to their escape during "The Stone Forest."
• Adaptational Personality Change: In the comics, Johanna showed great caution about Hilda's safety, and was a borderline Nervous Wreck who could give David a run for his money. In the original Bird Parade story, she refused to let Hilda go out in the city on her own, only changing her mind after a brief argument between them ensued. It's also strongly implied she hates the city. In the cartoon, Johanna sees the city much like Hilda sees the woods, is far more trustful of her daughter's ability to take care of herself, and is much more outgoing, though there are instances where she reverts to her original personality.
  • It borders on Composite Character as more than a few of Hilda's lines and observations from the comic are instead given to Johanna.
  • Season 2 restores much of her weariness towards Hilda's excursions, though overall they're still on better terms than they are in the comics. The main difference between the comic and cartoon versions of Johanna is that for the former, the thought of Hilda even leaving the house is enough to stress her out, whereas the latter is more upset that Hilda is keeping secrets and lying to her.
• Adults Are Useless: Zig-Zagged; sometimes she'll be unaware of Hilda's adventures, while other times she'll be right there with her. In season 2, she takes issue with being ignorant of what Hilda's doing, particularly because Hilda starts to lie to her.
• Anger Born of Worry: After discovering Hilda lied regarding having scout activities, when she was actually dealing with the kraken, she has finally had enough and chides her before grounding her.
• City Mouse: In the Netflix series, she grew up in the city and thus loves Trolberg while she never quite liked living in the country.
• Demoted to Extra: Not ''extra'' per se, but she doesn't appear quite as often in Season 2 compared to the first season, nor is her screentime in said episodes quite as long.
• Determinator: Throughout "The Mountain King" movie, Johanna went through great lengths to rescue her daughter; Who was taken from her by a Troll.
• Flight: In Season 3, she briefly develops the ability to fly after spending time in Fairy Country, though she loses it upon returning to the human world.
• Good Parents: She is an excellent mother to Hilda and she has her own character outside of being Hilda's mum at the same time. That said, she's not perfect.
• Go to Your Room!: Yells this to Hilda after an attempt to play a game devolves into an argument.
• Half-Human Hybrid: Season 3 reveals her father is a Fairy and her mother was human.
• Heroic BSoD:
  • In "The Stone Forest", she's sent into a brief one after the loss of their guide, believing that it could be ages until they escape the eponymous location - if they even can.
  • In "The Mountain King" movie, after failing to find her daughter and narrowly escaping a pack of rampaging Trolls, Johanna returns home in tears and is unable to sleep.
• Jerkass Has a Point: Her acts of Tough Love toward Hilda were not without merit, not just because Hilda lied to her and kept her Locked Out of the Loop, but it's worth remembering that in many of Hilda's prior adventures, Johanna has done her best to be helpful, patient, and reasonable to her daughter, even when things go miles past her comfort zone. From her perspective, Hilda's sudden persistence on lies was not only a huge betrayal of trust, but was utterly pointless in hindsight.
• Laser-Guided Amnesia: When temporarily transformed back into her ten-year old self upon entering the fairy mound to find Hilda, she also loses all of her post ten year old memories, and thinks she's there searching for her parents. Thus, when Hilda does run into her, neither recognize each other but do agree they're "in the same boat" and they should help each other find their parents.
• Mama Bear: Nothing is going to stop her from protecting her daughter, not even a troll. Or a Spider Frog.
• My Beloved Smother: Though her overprotectiveness is justified considering the supernatural forces going around. She's also self-aware enough to be wary of becoming this trope. In The Fifty Year Night, she has a minor breakdown in her car and questioning whether she is the kind of mother she herself would want.
• Named by the Adaptation: In the graphic novel Hilda's mother's name had not been revealed, but in the Netflix series episode 5 reveals that her name is Johanna. Still no last name though.
• Parents as People: She's a good mother who only wants the best for Hilda, but she's also a single parent with an unsteady career and an adventurous daughter who's more comfortable in the wilderness surrounded by monsters than in society.
• Reasonable Authority Figure:
  • In the Netflix series, she trusts Hilda's judgment and ability to take care of herself.
  • When Frida and David offer to help her find Hilda in Hilda and the Mountain King, she welcomes their support but delivers them home instead of taking them with her on the search, refusing to put them in danger.
• Refuge in Audacity: Name another person in the show who stared down a troll and lived to tell the tale.
• Say My Name: Tends to shout Hilda's name whenever she sees her in danger. Which is often.
• Starving Artist: A graphic designer who struggles to support both herself and her daughter.
• Struggling Single Mother: You better believe it. Not only does she have to deal with moving back to Trolberg after living in the wilderness for so long, but she also has to deal with her daughter growing increasingly rowdy and constantly heading off to dangerous, supernatural adventures without telling her.
• Took a Level in Cynic: Downplayed. For most of Season 2, Johanna began to question the whereabouts of her daughter and becoming increasingly worried about her constant adventuring. Johanna also began to wonder if she was being a good mother or not.
  • However, it turns out she took one before the series, when her parents abandoned her as a child.
• Tough Love: At the end of "The Beast of Cauldron Island", after finding out that Hilda lied to her, Johanna had no choice but to punish her daughter. Even Johanna felt unsure if it was the right thing to do, as the final image shows Johanna feeling worried about her daughter's happiness in adventuring. In "The Stone Forest", after both her and Hilda had an argument, Johanna told Hilda to go to her room to cool off, and felt bad about it, again.
• Waiting for a Break: She takes a job at a hardware store in order to make ends meet.
• Was Too Hard on Her: In "The Fifty Year Night", Johanna begins to question whether or not punishing Hilda was the right thing to do. Finally comes to realization at the end of "The Stone Forest" when she finally learned why Hilda wanted to go exploring.
• What Were You Thinking?: Yells this at Hilda after the Tide Mice are seemingly dealt with.
• Wrench Wench: Season 3 reveals that she's actually pretty handy at auto-repair, able to get her Alleged Car running again single-handed when it breaks down at the roadside in the middle of nowhere.

Alfur

Voiced by: Rasmus Hardiker
"I'm a writer rather than a fighter."

An elf that approaches Hilda to try to solve the conflict between her family and the elves in a peaceful way. He's very agreeable and always makes sure to look out for everyone he cares for, no matter the outcome.

---

• Alliterative Name: He's a member of the Aldric family, which would make him Alfur Aldric.
• Apologetic Attacker: The few times he's really been forced to fight back, he usually apologizes soon after, due to him being super polite.
• Ascended Extra: In the graphic novels, he was a One-Shot Character who only appeared in Hilda and the Midnight Giant and, outside of making an Early-Bird Cameo on the revised cover of Hilda and the Troll, he never appears again. In the series, however, his role is greatly upgraded, as he ends up moving to Trolberg with Hilda, becoming her Fairy Companion and one of the main supporting characters. He even gets an episode dedicated to him in season 2.
• A Dog Named "Dog": Álfr is Old Norse for 'elf'.
• Birds of a Feather: With Frida, sharing a love for studying, academic achievements and paperwork. They quickly befriend each other once they start interacting during "The Lost Clan".
• Cassandra Truth: The entire conflict in the episode “The Replacement” happened because his elf people (sans one) believed that his reports about his adventures with Hilda were too embellished and far-fetched to be considered real, even claiming that Hilda wasn’t a reliable eyewitness.
• Colossus Climb: He generally travels with Hilda and other humans by clinging to their ears and shoulders, or by jumping into the palm of their hands.
• A Day in the Limelight: The Season 2 episode "The Replacement" focuses on him.
• Demoted to Extra: He plays a considerably smaller role in the third season, always staying behind or doing something inconsequential while the gang ventures into bizarre locations and realms. His biggest purpose in said season is to infuse a bit of comic relief here and there. It's for this reason that in the final three books of the Tie-In series, he is completely absent except for one brief mentioning by Johanna.
• Fairy Companion: To Hilda and her friends.
• The Herald: He becomes this to Hilda early on, leading her on her journey to the elf king.
• Kindhearted Cat Lover: Season 2 reveals he owns a nitten named Peppercorn.
• Master of Unlocking: He's small enough to fit inside a lock, which leads to Hilda and friends relying on him whenever a door needs opening.
• My Species Doth Protest Too Much: While he loves paperwork as much as the next elf, he doesn't agree with their unfair eviction of Hilda and her mum.
• Nice Guy: Is genuinely friendly and helpful, to the point that he's the only elf who tries to help Hilda and her mom stay home when the elves try to evict them.
• Non-Action Guy: His character quote isn't a joke; he'd rather de-escalate the situation peacefully than get into fights. Season 2 does see him get into a combatitive situation or two, but he does not seem to enjoy it.
• Our Elves Are Different: He's a 2-inch-tall humanoid with Pointy Ears who is Invisible to Normals until the proper forms are filled out. Like the rest of his kin, his general appearance and characteristics are based on Iceland's elf folklore.
• Rattling Off Legal: Alfur does this verbally after giving Hilda some words of reassurance. Apparently all elves do this in case the person they're reassuring fails.
• Token Heroic Orc: Downplayed. The elves aren't evil, they just operate on Blue-and-Orange Morality, but Alfur is the only one who comes to Hilda and her mother's defense when the Little People decide to evict them.
• Viewer Name Confusion: Tropers could be forgiven for thinking his name is spelled "Alpha" due to British enunciation.
• Your Size May Vary: At his smallest depiction he can fit in a keyhole with room to spare, but in other scenes he is notably larger than that, taking up a good portion of Hilda's hand.

David

^{Click here for his Post-Time Skip appearance.}

Voiced by: Oliver Nelson, Arthur Smith Galiano (audiobooks)
"Oh cruddlesticks."

A naive boy who befriends Hilda when she moves to the city. David's a bit of a coward and somehow always has a bug on him somewhere.

---

• Adaptational Early Appearance: In the graphic novels, David makes his first appearance in "Hilda and the Black Hound". In the series, he makes his debut in "The Midnight Giant".
• Arbitrary Skepticism: Early in "The Fairy Mound" he and Frida are convinced Fairies aren't real, despite his friend having a pet Deerfox and being friends with a Nisse and Elf.
• Ascended Extra:
  • In the graphic novels, he was only a minor supporting character in "Hilda and the Black Hound", and had just 2 cameos in "Hilda and the Stone Forest". The animated series turns him into one of the three main characters and gives him a much more developed personality and character.
  • Whereas he did not appear at all in "The Mountain King" graphic novel, David has a significant role in the adaptation.
• Attention Deficit... Ooh, Shiny!: Gets distracted from holding a rope by a cool-looking rock.
• Author Avatar: Resembles the comic author Luke Pearson.
• Beware the Nice Ones: He has very little time for selfishness, laziness and cruelty, especially after hanging around with Hilda and gaining more confidence in himself. He's surprisingly harsh with Victoria Van Gale, the Marra and Frida when they offend him with their attitudes and actions, and can even get quite short with Hilda sometimes when he feels she's dragging them into danger without good reason.
• Black Bead Eyes: Has these eyes.
• Boyish Shorts: Except when it's winter time, David always wears shorts, regardless whether it's with his regular clothes, his Sparrow Scouts uniform or his school uniform. And—while not necessarily immature—he is easily the least bravest of the three main kid characters, with many of the creatures they encounter frightening him.
• Character Catchphrase: Oh, cruddlesticks!: used whenever he realizes he's in trouble or encounters something scary/unexpected.
• Companion Cube: He has two in the forms of stuffed animals: a bear named Roarin and a giraffe named Bertrand, who both get an apology when he throws them out of bed.
• Cowardly Lion: He's very vocal about his fears, but will reluctantly face them when need be.
• Death Is Cheap: He is killed twice in "The Eternal Warriors" via decapitation, luckily he is revived both times by Sigurd.
• Early-Bird Cameo: Along with Frida, he talks with Hilda briefly in Chapter Two, and gets a scene on the Sparrow Scout's float in Chapter Three.
• Failed a Spot Check: Doesn't notice the rock in his collection growing larger (or coming to life) every night.
• Friend to Bugs: Averted, despite always having a bug on him somewhere, he has no love for them. Ironically, in episode 13, he's still rewarded with the "Friend to Insects" badge.
• Hidden Depths: Whoever thought such a strange and cowardly boy was such a beautiful singer?
• Jerkass Has a Point: In "The Ghost." While he's very rude about suggesting Frida learn to clean her own room instead of trying to get the ghost who always did it to resume, by the end of the episode, even Hilda admits he's not wrong.
• Literal Metaphor: Last year when he auditioned for the talent show he didn't even make it on the stage. Literally—right as he cleared the stairs he knocked over a bunch of stuff that led to the curtains being torn down. This year he managed to make it on the stage—before inhaling a bug and knocking down a bunch of stuff again.
• Literal-Minded: Tends to take the most literal interpretation of any statement.
• Lovable Coward: He tends to be the first to run away or voice doubt about an adventure. Still he usually tags along anyway. Hilda and Frida even admit that they find his fear charming.
• Mythology Gag: The reason insects get stuck on him? In the comics he was looking for a specific insect to earn a Sparrow Scout badge, the story ending with several insects stuck to him. The joke is lost in adaptation.
• Nervous Wreck: He's usually the one in the group who is the most nervous or concerned about their adventures or the one who doesn't want to be involved in their situations.
• Off with His Head!: At the climax of "The Eternal Warriors", David gets decapitated by one of Viking's weapons. He gets better by the end though.
• O.O.C. Is Serious Business:
  • Frida is aptly shamed when he actually gets angry at her and tells her off for hanging out with the same girls that gave him nightmares and are bullies. It's his refusal to accept her help when packing that makes her swallow her pride and apologize.
  • In the episode "The Eternal Warriors", David acting like a Fearless Fool clues Hilda and Frida into the fact that he isn't quite himself.
• Precision F-Strike: Played With. David is incredibly friendly and polite at all times so to show just how annoyed he is with Frida at the end of "The Ghost" he drops a far more child-friendly F-Word.
  David: "You could just learn to tidy your own flipping room."
• Precocious Crush: In "The Jorts Incident", he seems to have gained a small one on Kaisa.
• Running Gag: People pointing out or checking that he has a bug on him; usually on the back of his head. His parents inspect him whenever he comes back home.
• Screams Like a Little Girl: Seeing Victoria van Gale's artificial nisse's skull and seeing a member of the Knudsen clan get bisected vertically causes David to let out a high-pitched one.
• Second Episode Introduction: He makes his first appearance in “The Midnight Giant”, the second episode of the series.
• Stating the Simple Solution: In "The Ghost," he suggests Frida learn to clean her own room after the ghost that always did it quits, but Frida isn't keen on the idea and Hilda doesn't want to give up because she promised Frida she'd resolve the issue.
• The One Guy: In his group with Hilda and Frida, he is the only male.
• The Team Normal: Downplayed to an extent, but he is a normal boy, while Frida is a witch (a human who focuses on the study of magic, which David has never tried) and Hilda is one-quarter fairy (but it doesn’t give her anything special beyond her blue hair).
• Took a Level in Badass: He seems to finally let go of his constant fears in the Grand Finale, jumping through the portal on the fairy mound to pull Hilda and Anders back out.
• Vocal Evolution: As seen in the first teaser for season 3, his voice is notably deeper than it was in seasons 1 and 2. Justified on two fronts; his voice actor hit puberty, and in-universe David is a year older than he was in season 2.
• Walking Disaster Area: When auditioning for the talent show, he'll crash into every breakable thing, tear down the curtains, and literally bring down the curtains.

Frida

^{Click here for her Post-Time Skip appearance.}

Voiced by: Ameerah Falzon-Ojo
"If I'm not perfect, then I don't know who I am."

A strong minded girl who befriends Hilda when she moves to the city. Frida is very intelligent but tends to over think things.

---

• Adaptational Early Appearance: In the graphic novels, Frida makes her first appearance in "Hilda and the Black Hound". In the series, she makes her debut in "The Midnight Giant".
• The Ace: Frida is the top Sparrow Scout with the most badges.
• Arbitrary Skepticism: Early in "The Fairy Mound" David and her are convinced Fairies aren't real, despite her friend having a pet Deerfox and being friends with a Nisse and Elf
• Ascended Extra:
  • Like David, she was only a minor character in the Graphic Novels, with some small roles in "Hilda and the Black Hound" and "Hilda and the Stone Forest". Here, she is one of the three main characters.
  • Whereas she did not appear at all in "The Mountain King" graphic novel, Frida plays a significant role in the adaptation.
• Berserk Button: Presumed slights against her perfectionism drive her into a rage.
• Birds of a Feather: With Alfur. They both love studying and paperwork, quickly hitting off when they meet each other in "The Lost Clan".
• Brains and Brawn: Frida is the brains to Hilda's brawn. This is the reason why Frida was chosen to be a witch due to her studious nature and thinking things through.
• Broken Ace: She puts so much stock on being perfect that the revelation that she isn't utterly crushes her, to the point that she drives both her friends away and forfeits the election for student council president.
• Control Freak: Frida has a plan of action always ready to go, and woe to anyone who deviates.
• Early-Bird Cameo: Along with David, she talks with Hilda briefly in Chapter Two, and gets a scene on the Sparrow Scout's float in Chapter Three.
• Fatal Flaw: Though she is a master planner, she tends to fall to pieces as soon as one thing doesn't go to plan (See For Want Of A Nail and Leeroy Jenkins below).
• For Want Of A Nail: Discussed. Learning that rooms don't just clean themselves make her question her entire life, as she realizes not having to take time to clean her room every day left her plenty of time to study and pursue extracurricular activities. She wonders who and what she would be like if she'd had to spend so much time learning to clean her room every day like everyone else.
• Jerk with a Heart of Gold: Frida can be a perfectionist and selfish Control Freak at times and she does not take it well whenever her perfectionism is called into question by others (to the point of getting aggressive and violent about it), but she is still a goodhearted person who cares about her friends at the end of the day. She grows out of this by season 2.
• Jerkass Realization: She realizes that hanging out with the marra was a bad idea, especially when they push her toward the maw of the Black Hound and vanish. Hilda and David help her get away and Hilda sacrifices her snacks to distract the Hound, so they can get to safety. This, plus David still being angry at her, motivates Frida to apologize. She also meekly asks Hilda for a ride since her parents didn't know she was out in the woods.
• Leeroy Jenkins: Jumps into the Vittra tunnel after her stolen sash, with no plan for getting back out again.
• Locked Out of the Loop:
  • She assumed that all rooms just cleaned themselves since hers seemed to and no one ever brought it up. She only learns that this isn't the case when the ghost who was tidying her room stops coming.
  • Although she appears in "The Nisse", Kelly keeps her out of the main group until the beginning of "The Black Hound", meaning she later needs to be brought up to speed about Tontu.
  • Later in "The Windmill", she has no idea who Victoria Van Gale is due to not being present during the events of "The Storm".
• Loss of Identity: Frida suffers a big one after she realizes she's not as clean and organized as she thought.
• O.O.C. Is Serious Business: When Frida decides to skip the Sparrow Scout's camping trip, Hilda and David know something is really wrong.
• The Perfectionist: Thanks to pressure from her parents, she always likes to be perfect and gets frustrated when she isn't. Discovering that bedrooms don't tidy themselves is enough of a shock to the system to send her on a downward spiral.
• The Pig-Pen: Is distraught to learn she's really this, since a ghost secretly cleaned her room while she slept all her life so she never had to learn to be clean and organized except with school and Sparrow Scouting.
• Schedule Fanatic: As shown in episode 4, she is precise about staying on schedule.
• Second Episode Introduction: She makes her first appearance in “The Midnight Giant”, the second episode of the series.
• Shoe Slap: When she had a fight with Hilda after the failed attempt to get her beloved book back, she threw a shoe at her, but Hilda was able to close the door before the shoe hit her.
• Training the Gift of Magic: Played With a bit, in the setting anyone can use magic, but being a witch here is more about studying and seeking knowledge. This makes Frida who loves learning and studying, an ideal canidate to become a witch, and she becomes Tildy's newest apprentice.
• Wrestler in All of Us: She is very proud of her wrestling badge.

Tontu (Alpha)

Voiced by: Rasmus Hardiker

A wearisome Nisse who is invited to live in Hilda's home after being booted from his old house.

---

• Ascended Extra: Appears during the final episode of the first season, and becomes a recurring cast member thanks to it.
• A Day in the Limelight: After becoming a main character in Season 2, he gets one episode in each season as a major character - those being "The Windmill" and "Stranger Frequencies".
• A Dog Named "Dog": Tontu (or tomte) is an alternate name for nisse in Nordic folklore.
• Deadpan Snarker: He may not have a visible mouth, but don't think he can't speak his mind (no matter how blunt it may be) in spite of that.
• Drop-In Character: Throughout Season 2, he will show up out of the Nowhere Space in Hilda’s home every now and then.
• The Faceless: Other than his nose, most of his facial features are permanently hidden under his fur.
• Food as Bribe: He refuses to let Hilda keep her stuff in his negative space... but Johanna can do so if she pleases, because she provides Tontu with lovely pancakes.
• Gag Nose: One that sticks out from his furry head.
• Jerk with a Heart of Gold: Underneath all the snark and cynicism, he's a good-natured guy and a valued member of Hilda's family.
• Mundane Utility: He agrees to let Johanna use Nowhere Space as an extra storage room.
• Running Gag: Through season 2, Tontu constantly tells Hilda that he won't let her use the Nowhere Space as her personal instant-travel system, but he always ends up yielding to her request for one reason or another.

Hilda's family

Astrid

Voiced by: Miriam Margolyes

Hilda's feisty grand aunt who lives in Tofoton.

---

• Cool Aunt: She is an eccentric, feisty, and outgoing person who adores both her niece and grandniece and dotes on them when they come to visit Tofoten. She also gives Hilda one of her charms when she leaves Tofoten.
• Cool Old Lady: Despite her old age, she is quite capable and very feisty.
• Deal with the Devil: At the end of Season 3, Astrid makes an offer to the Fairy Entity to exchange her life for that of Johanna's, and would have been killed were it not for the timely intervention of Victoria van Gale.
• Elderly Blue-Haired Lady: She has faded blue hair matching Hilda's, though it's revealed that her blue hair is due to her being a fairy.
• Flight: In Season 3, she regains the ability to fly—which she'd lost living in the human realm—after reconnecting to the Fairy Country.
• Foolish Sibling, Responsible Sibling: She is the responsible sibling to Phinium's foolish sibling, being the one to try and remind him that fairies aren't allowed to interact with humans.
• I Did What I Had to Do: She erased Johanna's memories of her parents' true nature to ensure she wouldn't try to go back for them, but deeply regretted it and later admitted she was wrong to do so.
• Obnoxious In-Laws: Downplayed. While she does not like Anders very much, she still allows him to join the family breakfast at the end of the series.
• Parental Substitute: She is Johanna's primary parental figure. Particuarly after Johanna's parents chose to abandon her and return to Fairy Country for her safety.
• Pointy Ears: While her ears are usually covered by her hair, it's revealed that she has pointy ears due to being a fairy.
• Protective Charm: She tends to make these kind of charms, to the point that she has made a mail order business selling these to tourists. They allude to her true nature as a fairy.
• Sitcom Arch-Nemesis: She does not get along with her neighbor — Pooka — due to his frequent tendency to come to her house and demand she give him her belongings. The two make amends in the final episode after he returns her belongings.
• Unusual Pets for Unusual People: She is an eccentric old woman who owns a Living Land Creature named Loam as a pet.

Anders (Unmarked spoilers)

Voiced by: John Simm

Hilda's father. He is an explorer who likes to travel around the world. However, because of his drive for adventure, he is rarely present in Hilda's life. Despite this, he still cares for her greatly.

---

• Bumbling Dad: He has tendencies to get into wild adventures on air and sticking up to a time table is not his thing. However, he greatly loves his daughter and spends with her as much time as he can.
• Disappeared Dad: He is rarely present in Hilda's life, to the point that he went unacknowledged in the first two seasons, with the only allusion to his existence being in The Mountain King, in which Hilda briefly asks Trylla if she has a troll dad and then being disappointed when she replies no, and a comment from Luke Pearson stating that "he was not in Hilda's life at the time". His absence from Hilda's life would finally be addressed in Season 3's "The Job", where it's explained that it's because of his constant traveling and adventuring.
• Good Parents: He’s far from the responsible parent, but he is truly loving and caring towards Hilda. It’s implied the two have a better understanding because of their similar personalities.
• Hands-Off Parenting: He didn’t stick around for much of Hilda’s life and happens to be just as reckless and risk-taking as Hilda is.
• Heel Realization: During the Season 3, he became guilty over not being in Hilda’s life more than he could’ve been. He gets better over it in Grand Finale, when he settles in Trolberg.
• Like Father, Like Daughter: It's abundantly clear that Hilda inherited her love of exploring and adventure from him, which he points out in "The Job", as he is an explorer who loves to go on adventures. The two are also prone to being reckless risk takers and getting themselves into dangerous situations.
• My Greatest Failure: Began seeing his Parental Neglect of Hilda as this.
• Papa Wolf: Though absent for most of his daughter’s life, he’s just as caring and protective towards her as Johanna is, demonstrated when he attacked thieves for talking bad to her or distracting a troll to ensure she’ll be unharmed.
• Parents as People: He truly loves his daughter and even came to Trolberg to see her again, but as Johanna says to Hilda, whenever he gets overwhelmed, he tends to disappear and go on adventures, which means he is often not present for long periods in her life, which he regrets when he sees her again in the third season. He presumably gets better about this by the end, as he is shown moving into an apartment in Trolberg in the final episode.
• Unseen No More: After being unacknowledged in the past two seasons, he finally makes a proper appearance in season 3.

Hilda's grandparents (Unmarked spoilers)

Phinium and Lydia

Lydia on the left. Phinium on the right.

Johanna's parents and Hilda's maternal grandparents. Phinium is a fairy and Lydia is a human-turned-fairy. They both reside in Fairy Country.

---

• Daddy Had a Good Reason for Abandoning You: After the 10 year deal with the Fairy Entity had expired, Phinium and Lydia chose to leave Johanna with her aunt and erase her memories of them to ensure that she can have a normal life in the human world, instead of having her return to Fairy Country and stay forever.
• The Fair Folk: They are fairies after all, and are initially shown draped in black cloaks and ominously hovering. That said, they're not at all malicious.
• Foolish Sibling, Responsible Sibling: In their youth Phinium was the foolish sibling to Astrid's responsible. He was the one who first broke the rule of not interacting with humans, revealing himself to Lydia.
• Muggle–Mage Romance: Phinium is a native fairy, while Lydia is a human who got turned into a fairy upon entering Fairy Country.
• Older Than They Look: Despite being as old as Astrid, they look like young adults instead of elders. The answer for why this is differs between the show and the novels. In the tie-in novels, this is because time in Fairy Country moves at a far slower pace than in the human world. However, in the show, it's implied by Astrid that this is the result of Fairy Country making them look young in Hilda and Johanna's mind.
• Pointy Ears: Phinium has pointed ears due to being a fairy from the Fairy Country, while Lydia—who was born human—does not.
• Prefers Going Barefoot: Both Phinium and Lydia are barefoot during all their scenes in Fairy Country. As a child, Phinium also preferred being barefoot.

Humans

Kaisa the Librarian

Voiced by: Kaisa Hammarlund
"Being a witch is all about knowledge and knowing the true shape of things than it is about spells and powers."

A mysterious librarian who seems to have knowledge and connection with the supernatural of Trolberg. Season two reveals she is a witch with a special title called Keeper of the Books and is responsible for all the books in the Witch's Tower.

---

• Ascended Extra: In season two she gets an episode dedicated to her and becomes an occasional adventure companion in other episodes.
• Blue-Collar Warlock: She looks more like a gothic cosplayer of a witch rather than the stereotypical witch, and she works at the Trolberg library.
• Canon Foreigner: She does not appear in any of the graphic novels and is exclusive to the series.
• Dark Is Not Evil: Her normal attire consists of several shades of black and grey, but she's always helpful when Hilda and friends need her assistance.
• Demoted to Extra: In the third season, she only has two cameos without any dialogue.
• Disproportionate Retribution: She was almost banished to the void for failing to get back a romance novel from her old mentor (although that was only a pretext for sacrificing her to the void to keep it happy).
• Encyclopaedic Knowledge: Appears to have memorized the exact location of every grave in Trolberg, though she pretends otherwise.
• Establishing Character Moment: Drops a book that's about the exact issue Hilda and friends are dealing with, then leaves soon after, quickly establishing she's a mysterious and knowledgeable individual.
• Everyone Calls Her "Barkeep": Is only ever called “Librarian”. Averted in season 2, where her real name is revealed to be Kaisa.
• Goth Girls Know Magic: She has a goth-y outlook and is implied (and outright stated in Season 2) to be a witch of some sort, carrying around tools to be used to summon the dead, protecting a section of the library full of grimoires and having a large knowledge of the supernatural.
• Inept Mage: Season 2 shows that she's not very good at magic and has a hard time memorizing spells if she doesn't have a book to look at. This causes her to feel ashamed and unable to face her old teacher, feeling that she had failed her.
• Keeper of Forbidden Knowledge: Guards the hidden section of the library where the spellbooks are kept.
• Magic Librarian: Season 2 reveals she is a witch. She works at the city's library and shows an impressive amount of knowledge about the supernatural, even offering Hilda a book about the exact subject of what they're looking for.
• Misplaced Accent: Inverted; of all the characters in the setting, she's the only one who speaks in an accent appropriate of the Norse by Norsewest setting. Almost everyone else speaks in one of various UK accents.
• Older Than They Look: No one draws attention to it, but she appears to be in her early twenties at the oldest. Yet a plot point revolves around her reclaiming out an overdue library book that she gave to her mentor "thirty years ago." Assuming she was an adult back then, that would make her at least in her fifties.
• Perky Goth: Despite her goth-y outlook, she is generally nice and sweet to the kids that come to the library, and most helpful to them.
• Reasonable Authority Figure: She gladly helps Hilda whenever she needs, and is cross, but firm, when Hilda finds the secret section of the library, which is full of supernatural books.

Victoria Van Gale

Voiced by: Rachel Atkins

A meteorologist that lives on the outskirts of Trolberg. Hilda is a big fan of hers due to her impressive precision during weather forecast... until she turns out to be an amoral Mad Scientist.

---

• Affably Evil: At first glance, Victoria comes off as a nice, if somewhat eccentric woman. She clearly loves her work and research, and will gladly give a tour of her Weather Station to everybody who visits. She can also be somewhat clumsy. Nevertheless, she she isn't above doing morally questionable things to achieve her goals, like abducting a baby Weather Spirit.
• Alliterative Name: Victoria Van Gale.
• Bad Liar: When her experiments go wrong, she just keeps telling people that everything is fine over her radio program. When hiding her secret lab, she claims it's her bedroom and she hasn't tidied.
• Broken Pedestal: Hilda is a big fan and listens to her broadcasts every day. She also refuses to believe David when he suggests Victoria might be a bit of a mad scientist. After finding out that Victoria kidnapped a young wind spirit, lied to everyone and put the entire city in danger, it's likely Hilda's impression of the woman has changed slightly.
• Canon Foreigner: She has no counterpart in the comic books and is an exclusive addition from the Netflix series.
• Early-Bird Cameo: Her station can be seen in the opening of Chapter One, and she is briefly hard on the radio in Chapter 7.
• Even Evil Has Loved Ones: Despite her Mad Scientist nature, she genuinely seems to care for the wildlife who come to her, and her artificial Nisse.
• Evil Counterpart: Like Hilda, she boldly seeks out the supernatural, but while Hilda seeks to work with and be in peace with magical creatures, Victoria is willing to use them for her own purposes regardless of the consequences. Also like Hilda, she doesn't learn from her mistakes easily, either.
• For Science!: Why she captures a weather spirit child, and later on why she tries to open up the Nowhere Space.
• Friend to All Living Things: The Season 2 episode "The Windmill" reveals that after the destruction of her weather station, she escaped to the woods and started living there. The animals of the forest really seem to love her, because they willingly flock to her.
• Genius Ditz: Tends to be scatter - brained and disorganized, but can predict weather changes down to the second.
• Hazy-Feel Turn: Victoria is too absorbed in her research to take any responsibility for the consequences, but for the same reason never bears Hilda any lasting ill-will for her interference. This never really changes, either - when she bargains with the fairy spirit to set Hilda free, she barely seems aware what she's doing for Hilda and is just excited for the opportunity to study Fairy Country forever.
• Ignored Epiphany: Her apparent reformation in "The Windmill" turns out to be flimsy, as she once again attempts to interfere with things she clearly has no control over — only this time, she nearly ends up getting all of Trolberg sucked into the Nowhere Space.
• Mad Scientist: David even calls her such.
• Meaningful Name: A gale is a term for windy weather.
• Muggle with a Degree in Magic: The episode "The Windmill" shows her that she is versed enough in Old Magic to conjure the power to make an artificial Nisse. And combined with her science background in meteorology, she can even jury rig a Magitek device to open a gateway to Nowhere Space.
• Put on a Bus: She survives the destruction of her weather station, but does not appear for the rest of the season.
  • At the end of the Season 2 episode "The Windmill", she is trapped in the an undisclosed location (revealed to be Fairy Country in season 3) with no way out, leaving her absent for the rest of the season.
• Sufficiently Analyzed Magic: It is her attempt to achieve this that leads Victoria to study weather spirits. She also applies this to the watchtower in Fairy Country, and manages to modify it to make a portal that takes her straight to the Fairy Entity.
• Weather-Control Machine: Her weather station doubles as one.
• Well-Intentioned Extremist: In the most literal form of the trope, Victoria's various experiments have the end goal of helping people and making the world a better place, but there is no limit on what she will do to achieve that goal.
  • In Season 1, she nearly destroys Trolberg in a severe storm in her attempts to control weather spirits, not to mention the fact she kidnapped a child to do so.
  • In Season 2, in order to curb overpopulation she rips a hole into Nowhere Space with black magic and technology. It of course goes wrong and risks sucking all of Trolberg into nowhere space like a miniature black hole.
• Would Hurt a Child: Kidnaps a child Weather Spirit to try to manipulate them.

Trevor

Voiced by: Reece Pockney, Edward Molony (audiobooks)

A neighbourhood kid of Trolberg who enjoys pranks. He and his group of friends were befriended by Hilda before she met Frida and David.

---

• Adaptational Jerkass: Trevor wasn't actually that bad in the original graphic novel. Inexcusable treatment of animals aside, he was pretty friendly to Hilda and showed concern for her a few times. He became a more villainous figure in the cartoon, with an extended storyline involving trying to prove Raven could speak at any cost, showing a deeply insecure side in the process. In the novelization, Trevor was stripped of any sympathetic qualities and became much more manipulative, mean-spirited and even violent, tricking Johanna into giving him the Raven and threatening to drown Raven at one point.
• Arc Villain: He becomes this when he captures the Great Raven to prove to his friends that it can talk.
• Ascended Extra: He was a pretty minor character in the graphic novel, but when the comic was adapted to an episode, the later half of the storyline was rewritten to make Trevor the main antagonist of it. In the novelization, he became the overarching villain of the book.
• The Cassandra:
  • Trevor was the only one besides Hilda to hear the Raven speak, and spends the rest of the episode trying to prove himself to his friends.
  • Based on his appearance in Chapter 5, where he jumps at the chance to accuse Hilda of being a witch, he has continued to do this.
• Disappeared Dad: His mom is seen sleeping alone in "Chapter 10: The Yule Lads", and no word is ever said about his father.
• Gang of Bullies: He leads a clique of bullies who enjoy harassing Hilda, David, and Frida.
• Hate Sink: To say that he's a big bully who's unlikable would be an understatement.
• Kick the Dog: Enjoys throwing rocks at birds.
• Kids Are Cruel:
  • Downplayed. While Trevor and his friends may be somewhat mischievous and have an extreme idea of fun, they aren't needlessly cruel, at least beyond what normal kids would get up to (although throwing rocks at birds is a bit much for that age).
  • Played straight in the novel Hilda and the Great Parade, where he's a mean-spirited bully at his best.
• Named by the Adaptation: He is never called by name in "Hilda and the Bird Parade".
• Unwitting Instigator of Doom: Causes the Great Raven to forget his identity, thus risking that the raven won't appear during the Bird Parade; something the people of Trolberg believe will cause a year of bad fortune.
• Vocal Evolution: His voice sounds a bit deeper when he reappears in “Chapter 10: The Yule Lads”, most likely due to his actor going through puberty.
• Why Did It Have to Be Snakes?: "Chapter 5: The Troll Rock" reveals that he developed ornithophobia as a result of his experiences with the Great Raven, which he naturally blames Hilda for.

Ms. Enid Hallgrim

Voiced by: Rachel Atkins

A teacher at the Ahlberg School. Hilda, Frida and David are in her class.

---

• Canon Foreigner: She does not appear in any of the graphic novels and is exclusive to the series.
• Miniature Senior Citizens: She is an elderly woman, and notably smaller than most other adults (in fact, she is only a bit taller than the kids in her class).
• Reasonable Authority Figure: In Hilda and the Mountain King, she reprimands Frida for disrupting the Safety Patrol presentation, but is actually proud of her for standing up for her principles, and later voices support for her students' protests.
• Stern Teacher: She has low tolerance for kids stepping out of line, and isn't above being biased towards kids she thinks are trouble makers, like Hilda. But when she sees Hilda face a troll, she warms up to the girl.

Principal Magnusson

The principal of the Ahlberg School.

---

• Canon Foreigner: He does not appear in any of the graphic novels and is exclusive to the series.
• Manchild: He's quite eccentric, to say the least.
• Skewed Priorities: In "Chapter 5", during the parents night, he only has eyes for the upcoming unveiling of a statue of Edmund Ahlberg, his idol. And when the troll attacking the school destroys the statue, he considers it an epic disaster.

Raven Leader

Voiced by: Rachel Atkins

The head scoutmistress of the Sparrow Scouts.

---

• Adults Are Useless: Subverted. She's always on the ball as a Sparrow Scout Leader. When Hilda and David inform her the Black Hound is in the woods, she immediately schedules an evacuation.
• Everyone Calls Her "Barkeep": She is always addressed by her title, Raven Leader. Her real name is thus unknown.
• Properly Paranoid: She tells everyone to stay in groups and not stray during the annual camping trip. That's because there are things in the wood like bullying marra and the Black Hound.
• Reasonable Authority Figure: She doesn't punish Hilda for wandering off twice with David during the camping trip, especially since the second time the kids tell her the Black Hound is in the woods. She definitely appreciates hearing the information. When Hilda tries to leave a third time to warn Tontu, however, Scout Leader Raven gets angry, stops her, and tells Hilda she'll be banned from camping trips if she leaves because it's dangerous to wander off alone.

Erik Ahlberg

Voiced by: John Hopkins

The new head of the Trolberg safety patrol, and a descendant of Edmund Ahlberg.

---

• Adaptational Early Appearance: In the graphic novels, Erik Ahlberg only appeared in the final book, "Hilda and the Mountain King". In the animated series, he is introduced in the first episode of season 2, even before the events from "Hilda and the Stone Forest".
• Adaptational Jerkass: In the graphic novel he already had quite some flaws, like being impulsive and short-sighted, but in the end he truly wanted to keep Trolberg and its citizens safe and was simply taking his job too seriously. In the animated series, he is an arrogant Glory Hound that cares more about making a name for himself than actually helping the city. This aspect gets toned down later on especially on Hilda and the Mountain King, though it is still clear that he's quite dedicated to making a name for himself he shows more overt concern for the lives of the people. Notably, in the original version of the Mountain King story, Erik actually hesitated to fire the Light Cannon and it took Trundle continuing his advance to provoke him for Erik to use it, whereas in the show he fires it purely because Trundle stands in the wall, rather than getting pressured into it.
• Animorphism: Frida accidentally turns him into a bug during "The Stone Forest". He doesn't particularly seem to notice or care.
• Badass Cape: Subverted; he may have a fancy cape, but he's decidedly not very badass at all. When he gets turned into a bug by Frida, the markings on his upper body and the wings on his back sort of resembles a cape.
• Bald of Evil: Though not quite evil, he is balding under his hat and quite the jerk.
• Chuck Cunningham Syndrome: He isn't seen or mentioned at all in the the third season. Justified, as he did step down as head of safety patrol at the end of the movie.
• Famous Ancestor: A descendant of Edmund Ahlberg, one of Trolberg's heroes, and feels a drive to live up to his ancestor's legacy.
• General Ripper: He is obsessed with Trolls, especially in the animated series and novelization. In the tie-in Novels, Hilda actually lampshades how Erik blames every problem he encounters on Trolls, no matter what.
• Glory Hound: Seeks to become famous like his ancestor was. He even puts his arm in a sling at the end of episode one of season 2, despite not seeming to have been meaningfully injured at all, just to garner sympathy, and even swipes a remote from a reporter's hand when he's being interviewed on TV.
• Hate Sink: He's not very likable at all with his arrogant behavior, unwillingness to listen to reason, Glory Hound tendencies and behavior towards trolls.
• Heel Realization: Once Hilda finally manages to show Ahlberg what Trundle's plan is, he tells the Safety Patrol to stand down and let the trolls into the city. Once all is said and done, after getting a medal, he retires and leaves Gerda in charge of the Safety Patrol clearly recognizing her as the one truly qualified to defend the city.
• Hero Antagonist: He's the closest thing this show has to any sort of antagonist (aside from Trundle), constantly getting in Hilda's way or ignoring her advice and unintentionally provoking magical creatures to invade Trolberg when he was trying to turn them away. He's not evil; he just doesn't know any better.
• Jerkass: Loudmouthed, self-assured to a farcical degree, and uninterested in what others have to say no matter how legitimate it may be.
• Jerkass Has a Point:
  • Even if he's much more willing to resort to harpooning the Lindworm instead of negotiating with it, he is right to consider it a menace to the townsfolk given it had been willing to murder 2 children and an elf simply for waking her up. Of course, Erik didn't know this and it's implied he just wanted to hunt the Lindworm out of a mixture of ego and despising anything weird that scares people.
  • While his persecution of trolls is extreme, it's not entirely unfounded as trolls are shown to have tendencies to turn violent at the drop of a hat, even with other members of their species as Trylla, the mother that swapped Hilda with her own troll daughter, admits.
• Lantern Jaw of Justice: Subverted Trope. He's got quite a chin, but he's an incompetently smug douchebag.
• Miles Gloriosus: One thing's for sure: he cares more about looking like a hero than actually being one.
• Nice Job Breaking It, Hero: Ahlberg's bell system and other safety improvements often cause the very problems they were put in place to prevent.
• Not-So-Well-Intentioned Extremist: Quickly proves himself this; while he does occasionally point out legitimate security concerns, like Vittra tunnels running under the wall being a way that trolls could get into the city, he's a Glory Hound who, in his debut episode, nearly gets himself and Hilda killed by a troll because he keeps ringing a bell despite having read Hilda's essay and thus knowing that trolls are more annoyed than scared of bells.
• Rude Hero, Nice Sidekick: He's the "Rude Hero" to Gerda's "Nice Sidekick". While he wants to look like the proud protector of Trolberg, he can be very obnoxious.
• Safety Worst: When he's not being a Glory Seeker, he often delves into this, for example, he gives the Sparrow Scout leader a very heavy book of his "updated" troll protocols, and his plan to automate the bell towers would have them ringing hourly, even during the day when trolls are stone.
• Would Hurt a Child: Tries to kill Hilda when she is transformed into a troll, even when Johanna is protesting and trying to stop him.

Gerda Gustav

Voiced by: Lucy Montgomery

Erik Ahlberg's right-hand woman and fellow member of the Trolberg safety patrol.

---

• Alliterative Name: Gerda Gustav.
• Beleaguered Assistant: To Ahlberg during season 2 and the movie. "The Replacement" implies she doesn't actually like him that much, a feeling which only grows stronger during "The Stone Forest", and comes to a conclusion in the movie when she listens to Hilda's warnings and flat out refuses to carry out Ahlberg's order to attack Trundle.
• Broken Pedestal: The events of "The Stone Forest" put a dent in her respect and confidence in Ahlberg, particularly when he attempts to take credit for "rescuing" David and Frida.
• Hyper-Competent Sidekick: Usually does all the work while Ahlberg prances around, swinging bells. Erik seems to realize this, as he makes her the new head of the Safety Patrol after retiring.
• Misplaced Accent: She has a noticeable German accent, which sticks out amongst the mostly British accents of the main cast.
• Reasonable Authority Figure: While she is a little too willing to follow along with Ahlberg's quest for glory we do see she is genuinely just trying to help people, and unlike him, she is willing to stop and listen to gain a better understanding of the situation.
• Rude Hero, Nice Sidekick: The "Nice Sidekick" to Ahlberg's "Rude Hero". She is much more reasonable and level-headed than the person she works for.
• Satellite Character: Barring the final two episodes of Season 2, she doesn't get a whole lot of development apart from being Ahlberg's associate. In fact, "Chapter 12: The Replacement" is the only time she's ever seen without him.
  • She eventually makes two solo appearances in season 3 (where Ahlberg doesn't appear at all), but neither of them are that substantial.
• Screw the Rules, I'm Doing What's Right!: In Hilda and the Mountain King, Ahlberg insists on shooting Trundle, but once Hilda explains Trundle's plan, Gerda staunchly refuses to obey Ahlberg due to the casualties that would occur.
• Women Are Wiser: She is shown to be far more level-headed and rational than Ahlberg.
• You Are in Command Now: Becomes the new head of the Trolberg Safety Patrol at the end of "The Mountain King".

The Bellkeeper

A man in charge of manning one of Trolberg's bell towers.

---

• Ambiguous Situation: He has faint grayish-blue streaks in his hair, and mysteriously vanishes when Hilda reunites with Johanna. Whether this means they have any connection is unclear. Season 3 reveals that Hilda's blue hair comes from her being part fairy, though whether this has any relevance to the Bellkeeper is still left ambiguous. In his brief encounter with Anders in the finale, the blue streaks are notably absent.
• Art Evolution: When he briefly reappears in "The Fairy Isle", his hair is recolored to a bright brown and the faint blue streaks that were present in his hair in season 2 are absent.
• Cynic–Idealist Duo: While he shares Hilda's concern about Ahlberg's extreme bell-ringing policy, he doesn't think anything can be done about it (at first).
• Everyone Calls Him "Barkeep": He's only ever called by his title.
• Reasonable Authority Figure: He isn't too pleased about Ahlberg's new policies, and understands that they're very unnecessary.
• Token Good Teammate: He's (initially) one of the only safety patrol members we see who thinks Ahlberg is full of it, and he isn't very happy with the new bell-ringing policies he's put around Trolberg. Thus, he tries to help Hilda disable the giant bell tower when Ahlberg sets all the bells around town to ring.
• Trademark Favorite Food: Like Hilda, he enjoys cucumber sandwiches.

Matilda "Tildy" Pilqvist

A kindly old lady who turns out to be a witch.

---

• The Archmage: She's even titled the Arch-Sorceress, and she lives up to the title just about any time she uses magic. Even closing up a gate to the Void of No Return and temporarily freezing a Time Worm are effortless feats for her.
• Ascended Extra: Goes from an extremely minor character in "The Bird Parade" to a recurring character in Season 2.
• Bait-and-Switch: Lives behind a labyrinth full of magical perils, has a number of intimidating monikers, and overall has some decent buildup as a force to be reckoned with. Would you ever expect someone like that to turn out to be a sweet old lady?
• Beware the Nice Ones: She's a kind old lady who'd invite strangers to join her for tea and board games... but she also happens to be among the most powerful witches of all time.
• Cool Old Lady: Who would have thought this old lady is actually a powerful witch?
• Deus Exit Machina: Although she becomes Frida's mentor, she rarely gets involved in the main characters' adventures. This was a deliberate choice made by the creative team behind the show, as Tildy is such a powerful witch that she could easily resolve most of the problems that Hilda and her friends encounter. It's especially noticeable in "The Jorts Incident", during which Tildy gets stuck in an argument with the Committee of Three, leaving it up to the children and Kaisa to deal with the main conflict, and the movie, where it is explicitly stated right when Frida gets involved that witch magic is not compatible with troll magic.
• I Was Quite the Looker: An old portrait of her shown in The Witch and her younger self depicted in The Fifty Year Night shows that Tildy was a rather beautiful young woman.
• In-Series Nickname: Insists most people call her "Tildy".
• Never Mess with Granny: Despite her old age, she is still a very powerful witch you don't want to anger.
• Power Floats: She sometimes gets around by floating above the ground.
• Reasonable Authority Figure: Is pretty smart and sensible, which is good when she has to deal with the three younger witches, who are not as smart and sensible as her.
• Try to Fit That on a Business Card: Though she's a kindly old lady, she has numerous intimidating titles, including Enchanter of Livelihoods, Grand Alchemist of the Dark Communion of Halgar, First Blood Sister of the order of the Black Candle, and another title that starts with "Tormentor of the".

Trevor's Mother

Voiced by: Rachel Atkins

The mother of Trevor who looks out for him.

---

• Ascended Extra: In the original "Hilda and the Bird Parade" graphic novel, Trevor briefly mentions her. She actually appears in person in the animated series.
• Hate Sink: Her rude attitude and the implication that Trevor got his bullying behavior from her erases any pinch of likeability from her.
• Horrible Judge of Character: She believes that Hilda is trouble and advises Trevor to stay away from her, unaware that he himself is a mischievous brat.
• Inconsistent Coloring: Back in Season 1, she had dark brown hair just like her son. Come Season 2, her hair is now black.
• Jerkass: Oh, so much. She actually refers to Hilda as "that monster" to Johanna (who is Hilda's mother), she yells at Twig while calling him a rat which scares him away, and when Trevor screams at night his mother's first instinct is to tell him off.
• Like Father, Like Son: Despite what she tries to be, she is clearly unfriendly just like her son. And according to Frida, who calls her "the queen of naughtiness", she was quite a troublemaker herself.
• Mama Bear: Even though she acts harsh, she is shown to be quite protective of Trevor, given how she angrily approached Johanna of her daughter's "bad influence" on him.
• Prim and Proper Bun: Has her hair in a bun, which reflects her attitude of being prim and disapproving of any trouble. But make no mistake, this does not mean she is friendly.

Louise

Voiced by: Jian Andany

Louise is a quiet and introverted kid who keeps to herself, but is also highly observant.

---

• Awesome by Analysis: As an introvert observer, Louise can pick up things that people usually don’t notice at first sight, such as that the sea monster is an illusion created by Eugenie to trap them as an audience in a never-ending performance, or that he laughs whenever someone is about to make a mistake.
• Camera Fiend: She is always carrying a camera around with her and is often shown taking photos of everything around her. She also ends up using it as a weapon against Eugene once she realizes it exposes his illusions.
• Hidden Depths: While her quiet demeanor may suggest otherwise, it's revealed at the end of "The Laughing Merman" that she deliberately hid the map because she wanted to go on a wild adventure with Hilda and co., suggesting she has the same drive and love for adventure that Hilda has.
• The Quiet One: She is incredibly introverted and quiet, so much so that Hilda and her friends didn't recognize her and thought that she was a new member of the Sparrow Scouts at first, despite having been in the scouts for a year. This has its advantages, though, as her tendency to be quiet and on the sidelines means she is incredibly observant and able to see things the others don't, which proves vital to outwitting Eugene.
• Sixth Ranger: She becomes the fourth member of Hilda's friend group at the end of "The Laughing Merman", turning the "Freaky Friends" into the "Freaky Four".
• What Happened to the Mouse?: Despite being accepted into Hilda's friend group at the end of "The Laughing Merman", she effectively disappears from the season outside of a couple of brief cameos in "The Forgotten Lake" and "The Fairy Isle". Justified as, by her own admission, she’s a quiet introvert, and while she enjoys company, she prefers hanging out with a small circle of close friends, and spends most of her time on her own.

Halvor

A young boy who is known as "The Giantslayer".

---

• A Child Shall Lead Them: He is in charge of the village that Hilda, Twig, and Wood Man end up in, even though he is no older than Hilda.
• Dark and Troubled Past: He became a giant slayer after his original home was destroyed by a giant.
• Foil: Like Hilda, he had his original home destroyed by a giant. However, unlike Hilda, who accepted the outcome, Halvor became obsessed with revenge and chose to slay the giants in retribution.
• Heel Realization: He realizes the error of his ways and begins to work with the giants to save the village after Hilda points out to him the destruction of village caused by his war against the giants, showing him that he is no better than the giants he was facing off.
• Red Baron: He is known as "The Giantslayer" by the villagers. As he later admits to Hilda, however, he has never actually slayed a giant.

The Polecat

A shady and greedy figure who is out for treasure.

---

• Adaptational Jerkass: In the animated series, he is quite affable and gets along well with Anders. He even offers Anders to use his truck. In the novelization, he is more of a jerk who quickly gets annoyed by Anders when Anders keeps asking more details about the job, like where to find the Castle Ruins. He is also far more reluctant here to let Anders use his truck, only doing so when there's no other option.
• Animal Theme Naming: He is named after the European polecat.
• Coat Cape: He is shown to wear his jacket in this fashion, emphasizing his shady nature.
• Everyone Calls Him "Barkeep": He is only referred to as "The Polecat". His actual name is never revealed.
• Greed: His motivation for getting the troll's treasure chest in the castle ruins. He even gets money bags in his eyes when he finds out about the treasure.
• Small Role, Big Impact: The Polecat doesn't have much screen time in "The Job", but it was his hiring of Anders that brought Anders and Hilda to the castle ruins, which leads Anders to get abducted by the fairies, causing Hilda to later go to Fairy Country to rescue him after receiving messages from him on her radio. To put it briefly, The Polecat is indirectly responsible for kickstarting most of the third season's second half.
• What Happened to the Mouse?: He never appears again after "The Job".

Trolls

General

Fearsome monsters that rove the country side, by day they are just large oddly shaped rocks but when night comes you better be as far away as possible. They are the main reason Trolberg has a wall surrounding it.

---

• All Trolls Are Different: They are based heavily on traditional Scandinavian folkloric depictions of trolls. While most trolls seen in the show resemble the one pictured above, Season 2 introduces a wider diversity of troll appearances, including hairy individuals. Hilda and the Mountain King also goes into significantly deeper detail about their culture and society.
• Always Chaotic Evil: Averted. While most of the humans (bar Hilda) view them as a fearsome and violent species (until The Mountain King), most of the trolls introduced have had a legit reason for going after the main characters and some of them (like Trylla) are friendly to them. This is emphasized further in The Mountain King, as Trylla states to Hilda that trolls are just as morally complex and capable of good and evil as humans are.
• Androcles' Lion: One early on returns Hilda's journal to her after she helps remove the bell tied to its nose. See Gag Nose.
• Cephalothorax: At least a few trolls are shown to have proportions like these.
• Creepy Shadowed Undereyes: For a pretty intimidating expression.
• The Dreaded: So much so that the citizens of Trolberg had to build a wall to keep themselves safe.
• Gag Nose: Troll noses are so long that the troll themselves cannot reach the end of them.
• Glowing Eyes of Doom: Troll eyes tend to glow white or red, the latter especially for aggressive trolls. This extends to Hilda when she's turned into one, her pupils glowing red when she's in the shadows.
• I'm a Humanitarian: They are repeatedly claimed to be this by the Safety Patrol and some of the kids. While some do eat meat, trolls eating humans are never witnessed. Given the true nature of the trolls, they are implied to be a subversion, as there is no actual documented account of someone actually being eaten by a troll, and the only accounts are rumors.
• It Can Think: Up until Hilda and the Stone Forest and Hilda and the Mountain King, trolls were usually assumed by the humans of Trolberg to be little more than snarling monsters. Hilda and Johanna find out firsthand however that trolls are much more sophisticated than they expected, possessing the same intelligence, social and cultural complexity, and range of morality as humans.
• Knight of Cerebus: Despite the Gag Nose, the threat they pose is still taken seriously by both the series and most human characters, and their presence is followed by an intimidating leitmotif. Even Hilda shows at least a reasonable level of caution around them.
• Mama Bear: In Chapter 5, a troll digs under the Trolberg wall with her bare hands and charges into the heart of hostile human territory in order to get her baby back.
• Multiple Head Case: The bully troll has two heads and is significantly larger than the others.
• Non-Humans Lack Attributes: Trolls go about nude, but lack any genitals or sexual characteristics. This extends to Hilda, when she is transformed into a troll.
• Sensory Overload: The reason bells are used so extensively against trolls is because their ringing causes horrendous pain, as poor Hilda learns the hard way.
• Smash the Symbol: A troll objects to the brand new statue of a troll slayer, and smashes it on its way out of Trolberg.
• Taken for Granite: Trolls are turned to stone by sunlight, but return to normal at night, or in a darkened room.
• Token Evil Teammate: The two-headed troll from Season 2 bullies and steals food and treasure from his fellow trolls with zero provocation.
• Truly Single Parent: As revealed in "The Mountain King" movie, Trolls tend to only have one parental figure. When Hilda (who was just turned into a Troll) asks Trylla if she had a Troll Dad, Trylla responds that Trolls aren't born the same way humans are. Trylla also stated that Baba appeared to her one day, and claimed the baby Troll as her own.
• Underground City: The majority of all Trolls reside in a vast underground cavern known as "The Stone Forest". It is here where the Trolls spend their everyday lives in solitude without the risk of being turned to stone during the day.

The Two-Headed Troll

A hulking, powerful Troll with two heads.

---

• Adaptational Early Appearance: In the graphic novels, The Two-Headed Troll was introduced in "Hilda and the Stone Forest". Here, he debuts in the first episode of the second season, "The Troll Circle".
• The Bully: One of the stronger trolls, it takes things from other trolls and hordes it for itself.
• Multiple Head Case: As his name implies, this Troll was apparently born with two heads.

Baba

^{Click here for her other appearance (spoilers).}Human form

Voiced by: Agnes Peacock

A baby Troll who befriends Hilda and Johanna in the Stone Forest.

---

• Adaptational Early Appearance: Baba makes her first appearance in the series in "The Old Bells of Trolberg", while in the graphic novels, she wouldn't show up until main Stone Forest storyline.
• Black Bead Eyes: When Baba was turned into a human, her eyes were changed from glowing white, to simple black dots.
• Charlie Brown Baldness: When Baba was turned into a human, she still doesn't have a single piece of hair on her head.
• Cute Monster Girl: Despite being a baby Troll, Baba is rather quite adorable.
• Foil: To the Troll Baby from season one's "The Troll Rock". While the Troll Baby was shown to be quite violent and destructive, Baba is more calm and cheerful.
• Morphic Resonance: When Baba was turned into a human, she still resembled her original Troll self, just with human skin and teeth.
• Oblivious Transformation: It is all but implied that Baba has no idea that she was turned into a human.
• Verbal Tic Name: Johanna starts calling her "Baba" because that's apparently all the baby Troll is able to say. Interestingly, Trylla addresses her the same way after they are reunited, suggesting that "Baba" might really be her name.
• Wild Child: Due to having no knowledge of the human world, the now human Baba is shown to be quite destructive. Johanna had a hard time trying to tame her.

Trylla

Voiced by: Rachel August

A Troll mother who befriends Hilda and Johanna in the Stone Forest.

---

• Adaptational Early Appearance: In the graphic novels, Trylla debuted in "Hilda and the Stone Forest". In the series, she first appears in "The Old Bells of Trolberg".
• All There in the Script: She's unnamed in the series and even Hilda and the Mountain King, with her name only being revealed by the Netflix subtitles.
• Ambadassador: Following the events of Hilda and the Mountain King, she appears to become an ambassador between the Troll community and Trolberg, helped by her friendship with Hilda.
• Benevolent Monsters: She is one of the first unambiguously benevolent trolls introduced in the series, shielding her daughter when she sees Gryla coming, and helping Johanna escape the Stone forest. While she does swap Hilda and her daughter with a changeling spell, she says she did so to provide a safe life for her daughter and Hilda with the freedom she craved.
• Easily Forgiven: Considering that she did realize that using the changeling spell was wrong, neither Hilda nor Johanna hold any grudge against her.
• Gentle Giant: Despite her mistakes, she's ultimately a kind, motherly individual and works hard to keep her daughter safe. She also genuinely cares for Hilda and tries to act as a mother for her after swapping her and Baba.
• I Did What I Had to Do: This was the reason why Trylla used the changeling spell on Hilda in the first place. All Trylla wanted was to give her daughter Baba a better life amongst the humans.
• My God, What Have I Done?: This is Trylla's reaction when she realized that using the changeling spell on Hilda was wrong.
• Named by the Adaptation: The subtitles for Hilda and the Mountain King reveal her name to be Trylla.
• Unwitting Instigator of Doom: By using the changeling spell on Hilda, Trylla unknowingly caused a chain of events that led to Trundle being released from his prison.
• Vocal Dissonance: She's a hulking troll the size and shape of a large boulder, but speaks with a very soft, high-pitched voice.

Trundle (Unmarked Spoilers)

^{Click here to see him with his eye}

Voiced by: Dino Kelly

An enormous troll found trapped in a cave filled with bells. Turns out to be the Mountain King who was imprisoned for wanting to wage war on Trolberg.

---

• Affably Evil: He acts kind of aloof to Hilda to get him to release her from his prison, and even when released still speaks in a polite tone despite planning to rally his kin for an invasion on Trolberg that will destroy her home in the end. He's also sincere when he tells Hilda to appreciate her troll mother, likely because he misses his.
• Anti-Villain: His ultimate goal is to reunite the trolls with their mother, Amma, who's buried underneath the city. He does not mind attacking the city nor dying himself in order to do it and shows no hesitation to get humans harmed in the crossfire of either his attacks, that of the other trolls or Amma awakening.
• Attack of the 50-Foot Whatever: He towers above normal Trolls and even bigger than Trolberg's walls.
• The Bad Guy Wins: Trolls do get to enter Trolberg and Amma is awakened to be able to talk to her children once more. Except Trundle only meets that victory halfway; Hilda's quick thinking and Erik being forced to meet a Heel Realization allow the Trolls to access the central point of Trolberg and meet Amma yearly, effectively mending race relations and bringing peace to the trolls at last.
• Big Bad: Of Hilda and the Mountain King, as the most major threat of the film due to his goals spelling disaster for Trolberg and its inhabitants. Even though he dies before the film ends his actions still almost lead to the destruction of Trolberg.
• Cyclops: He is revealed to be one after he regains his eye.
• Even Bad Men Love Their Mamas: He is by far the most cruel of all trolls, showing apathy and even slight eagerness at destroying Trolberg and possibly killing innocent civilians. But everything is ultimately done for the sake of reuniting trollkind (himself included) with their mother, Amma, who they all love dearly.
• Even Evil Has Loved Ones: No matter that he and his brother are now enemies with no real chance of reconciliation, Trundle still cares about him and while he's not deterring from his goals for his brother's sake he also won't truly harm him to achieve them, only ordering him pinned down and restrained by his troll army to keep him from interfering.
• Even Evil Has Standards: He may want Trolberg destroyed, but he goes out of his way to avoid stepping on Hilda after she unwittingly freed and restored him to power rather than eliminating her (which ends up letting Hilda undo the worst of his plans post-mortem), and he does point out that Trylla is earnestly trying to care for Hilda as a motherly figure rather than trying to harm her. He's the Big Bad, but he wants to awaken Amma for the sake of all trolls — anything after that, whether it destroyed Trolberg or not, was up to Amma and his people.
• Evil All Along: At first, he seemed like a friendly, reasonable troll who was the only one willing to help Hilda become a human again. After she frees him from his cave and gets his eye back though, it becomes clear not only that he's the Mountain King, but also what he's going to do to Trolberg will bring about its destruction and he doesn't cares one bit if the humans are harmed or killed.
• Evil Counterpart: To Jorgen. Both are giants that Hilda befriended and offered to help them with their problems. The main differences between them is that while Jorgen only wants to be reunited with his lost love, Trundle wants to be released from his prison in order to gather up all of the Trolls and wage war on Trolberg. Another key difference is that whereas Jorgen destroyed Hilda's old home by accident, Trundle wants to destroy Trolberg on purpose in order to wake Amma from her slumber.
• Evil Former Friend: Slight case with his brother, who shows he still loves Trundle but the violent ways the Mountain King believed necessary for Amma's reunion with her children divided them and their respective followers and in the present day they were enemies even if not willing to actually harm one another.
• Exact Words: Quotes "I'm not here to fight anyone." to his brother. And true to that, after destroying the bells and the wall, he never makes a move to fight against the humans, not even defending against their attacks. In fact, he lets his fellow trolls do the fighting and even has them pin down his brother to keep him from interferring.
• Eyeless Face: He's noticeably eyeless, with only a massive lump where his eyes should be. Turns out he did have one eye before his brother took it out of his head.
• False Friend: He pretended to be Hilda's friend in need in order to be released from his prison.
• Foreshadowing: To him being Evil All Along.
  • After Hilda gave him some troll mead, he states he can pull off the antlers of a forest giant. Indicating early on that he is quite the violent troll.
  • Once Hilda deals with the bells, Trundle laughs before congratulating her on her "human trickery".
• Giant Eye of Doom: The giant red orb that he ordered Hilda to find was actually his eye and once he retakes it he goes on to try and realize his plan. Those who enter inside it witness a prophecy that tells of the Trolls invading Trolberg; eventually leading up to Amma's awakening.
• Go Out with a Smile: He faces his death almost to a gleeful extreme. Not even bothering to defend himself from the Safety Patrol's Light Cannon.
• Hoist by His Own Petard: A posthumous instance. Trundle planned to incite the humans of Trolberg to attack the trolls, waking up Amma. He is willing to die to make this happen and allows himself to be killed by the Safety Patrol's Light Cannon. However, his death prevents him from causing any more mischief directly, and he also leaves his red eye behind, which is just what Hilda needs to make Erik Ahlberg see what the trolls want and stand down.
• Literally Shattered Lives: The Light Cannon causes him to crumble into boulders upon death.
• Motivational Lie: Trundle enlists Hilda's aid by claiming he can reverse Trylla's spell and make her human again. Once he's free, Trundle quips that they both "got what we want", suggesting he never intended to honor the deal, assuming he even could.
• Spanner in the Works: Had he not given Hilda the task of retrieving the giant red orb, she would have never reunited with her mother. Which in turn led to Trylla being reunited with Baba. Thus, the changeling spell would never have been broken.
• Thanatos Gambit: His ultimate plan was to provoke the humans of Trolberg into attacking his army of trolls so that Amma would reawaken and destroy the city. The smile on his face as he gets killed by the Safety Patrol's Light Cannon indicates he was all too willing to give his life if it meant his victory.
• Violence is the Only Option: His whole plan is pure violence from start to end until Amma is awakened, whether it is his death and other Trolls being harmed that wakes her up or them leveling Trolberg until they reach Amma, it's clear he doesn't consider talking things out a choice for his goal and even a human like Hilda helping him won't make him deviate from his destructive violent ways.
• Walking Spoiler: Hard to talk about him without revealing that he's the Mountain King and Evil All Along.
• Well-Intentioned Extremist: His ultimate goal isn't to conquer or destroy Trolberg. It is to reunite the trolls (including himself) with their mother, Amma who sleeps beneath the entirety Trolberg, but his utter apathy and even slight eagerness at destroying Trolberg still means he's an antagonistic being in the end and even his own brother is shown to not be willing to stand for the senseless destruction that Trundle believes necessary for his goals.
• Your Size May Vary: While he's always large, he's small enough to fit in the cave he's imprisoned in. After regaining his eye, however, his head nearly takes up the whole entrance and he has to rip it open wider to get out.

The Mountain's Troll (Unmarked Spoilers)

"I can't let you do this, brother."

A large troll guarding the castle of the Mountain King from anyone who came looking for the King's hidden treasure hoard. Hilda believes he is the Mountain King at first; he isn't, but he does turn out to be related.

---

• Adapted Out: He has a key role in the graphic novel explaining the truth about Amma, Trundle, and the red eye to Hilda, but this scene is cut from the movie; Frida uses her magic to help Hilda reveal the truth about Amma instead.
• Attack of the 50-Foot Whatever: Like Trundle, his brother, he towers above normal Trolls.
• Due to the Dead: With the trolls welcomed into Trolberg, he pays his respects to his deceased brother.
• Good All Along: He at first appears as a dangerous and evil troll that tries to crush Hilda for trying to retrieve the red orb and Hilda believes he's the nefarious Mountain King that wished to wage war on the humans of Trolberg. He eventually turns out to be the brother of the Moutain King, Trundle, and is only trying to stop his brother from harming the inhabitants of Trolberg which is why he tried to stop Hilda in her quest.
• Good Is Not Nice: All that he did was meant to protect the city from Trundle's plans, and he was all too willing to attack Hilda (a child) when she stole the red orb from the king's hoard showing that he would absolutely not let anything that could further Trundle's goals happen even if it meant crossing a few lines to ensure so.
• Mistaken Identity: Hilda believes him to be the Mountain King, when she steals the red orb from the king's hoard. Turns out to be not true, as he was the one responsible for stopping the mountain king who is his brother. Seems to be intentional as he appears in the title screen.
• No Name Given: He isn't given any name of any kind. And since he's not the Mountain King he doesn't get a title either.
• Red Herring: He was initially thought to be the Mountain King. But it turns out latter not to be the case.

Amma (Unmarked Spoilers)

Frida: Nothing was ever stopping her from getting up.
Hilda: But she didn't do it. She stayed there, cut off from her children, for us... for our sakes.

The mother and grandmother of all Trolls.

---

• Ambiguously Related: Hilda and the Midnight Giant and Hilda's Book of Beasts and Spirits both mention of a giant named Bjorg as being the ancestor of trolls, raising the question if he and Amma are related in some way. Unfortunately, Hilda's World: A Guide to Trolberg, the Wilderness, and Beyond muddles the problem further by claiming that Amma predates the giants, which only raises further questions about the ancestry of trolls.
• Attack of the 50-Foot Whatever: Larger than the entire city of Trolberg. In fact, her size is a huge problem for both her and Trolberg, as she can't even sit up, never mind stand, without destroying the city.
• The Ghost: Downplayed in that she is depicted in a silhouette, yet we never see her in person in the present day. For good reason - if she were seen in the present day, it would be after she leveled the entirety of Trolberg as a result of her getting up.
• Green Thumb: The trolls all bloom different forms of flora after bathing in her presence.
• Heroic Sacrifice: Willingly stays underground, away from her children, in order not to disturb the city above her. If she wanted to, she could stand up any moment, but that would destroy the city.
• Mama Bear: The only thing that can convince her to get up is if the people of Trolberg were to attack her children, which is what Trundle tries to provoke the Safety Patrol into doing.
• Mother of a Thousand Young: All of trollkind came from her. She's also a grandmother to a second generation of trolls.
• Terrain Sculpting: She built the mountains around Trolberg to house her children.
• Walking Spoiler: Her existence is the main source of the conflict of the movie and by extension, the series as it is her presence that beckons the Trolls towards the city.

Elves

General

A society of tiny elves that live around the house that Hilda's grandfather built with one thing in common; they're obsessed with paperwork.

---

• Black Bead Eyes: All elves are designed with these eyes.
• Can't Argue with Elves: They have paperwork!
• Complexity Addiction: Downplayed, but their processes are full of paperwork and bureaucracy. It's revealed in "The Lost Clan" that they are much better now than before, when people were exiled by presenting unfinished paperwork to the king.
• Inherent in the System: The reason it takes so long for Hilda to reach an agreement with the elves is that no one person is actually responsible for the war. The Prime Minister only suggested it to get elected and the King only goes along with it because all the paperwork was properly filed.
• Insane Troll Logic: Decide to evict Hilda and her mum for stomping around their county. They only did that because they couldn't see the elves? They should have filled out the proper paperwork! They didn't because they didn't even know the elves were there because they couldn't see them? They should have asked! They didn't ask because they didn't know there was any need for paperwork because they didn't know the elves were there because they couldn't see them? Nonsense! The paperwork was all laid out and not that difficult to find.
• Invisible to Normals: Or to be more specific, to anyone who hasn't filled out the proper paperwork.
• Jerkass Has a Point: When two giants unwittingly step on Hilda and her mum's house, Hilda realizes how the elves feel with her and her mum unwittingly stepping on their houses all the time (even if they can't see or touch them), prompting her to agree to move to Trolberg.
• Leaning on the Fourth Wall: The Running Gag where they point out they don't even have hands, which is true due to the stick figure animation style of their limbs.
• Lilliputian Warriors: Especially when they ride rabbits.
• Magic A Is Magic A: Exaggerated, and Played for Laughs. Almost everything magical about them is done through magically binding contracts...and lots of them!
• Medieval Stasis: Averted. The elves have advanced greatly since the time when the lost clan was banished. Despite the fact that they still fight with spears and wear very old-fashioned clothes, their architecture and government is comparatively modern. They even seem to have implemented a level of representative democracy.
• Obstructive Bureaucrat: Elves love paperwork and create any kind of situation where they might be necessary just because. They even send Alfur to make reports on human for no reason other than they want to receive more paperwork.
• Our Elves Are Different: They're based primarily on the Huldufólk, or "Hidden People", of Icelandic folklore, sharing their invisibility, tiny size, and architectural style.
• Running Gag:
  "My hands are tied! And I don't even have hands!"
• Serious Business: Paperwork and procedure. They used to be much worse about it, with unfinished paperwork presented before the king being considered treason.
• Unstoppable Mailman: Rather in keeping with their deep respect for paperwork, the elfin courier relay won't let anything stop them making a delivery, whether a freezing Scandinavian snowstorm or the letter being addressed only to 'Mum'.

The Lost Clan

Bartell, leader of the clan

A group of elves, descendants of the Bragga family that was exiled years ago. Much more savage and averse to paperwork, Alfur want to try to end their exile.

---

• Alliterative Name: The leader of the clan is named Bartell, a member of the Bragga family.
• Ascended Extra: They have quite a few appearances in Season 2.
• Barbarian Tribe: They're basically the elves' equivalent of one - fierce warriors of the wilderness who prefer to solve problems using force.
• Blood Knight: Played for laughs; Bartell really wants "COMBAT!" to be the answer to his clan's problems, mainly in Season 2.
• Canon Foreigner: They do not appear in any of the graphic novels, but are exclusive to the series.
• Didn't Think This Through: Capture David as a hostage, then stand around awkwardly when they realize they don't know what to do with him since they've never had a hostage before.
• Disproportionate Retribution: They were exiled as a result of forgetting to sign thrice the document they were making. At the time, presenting an unfinished document to the king was treason.
• Hidden Elf Village: Even by elf standards! They're in a fairly secluded location by the Trolberg wall where even humans rarely venture, unseen by humans and other elves alike.
• Horse of a Different Color: Many of them ride rabbits while on the ground and pigeons while airborne.
• I Choose to Stay: Once the contract has been made null, they are free to come back to the Northern Counties, however, they've been living so long within the walls, they decide they might as well stay there, since that is their new home. They give No Elf's Land to Alfur's family, as a result.
• I Gave My Word: Due to their aversion to paperwork, they honor agreements by keeping their word... and COMBAT!
• Know When to Fold 'Em: Don't even attempt to fight the Kraken when it emerges and refuse to when prompted.
• Medieval Stasis: Justified. As they have been cut off from all other elves and as such did not enjoy the advances that allowed their cousins in the northern counties to avert this trope.
• Never Mess with Granny: One of their strongest warriors seems to be an old rabbit-rider woman named Agnes, she has so far been undefeated in their equivalent of jousting.
• No Sense of Personal Space: After the Lost Clan befriend Hilda and co., Bartell is a little bit touchy-feely towards Alfur, who doesn't seem to like it all that much.
• Perma-Shave: Averted. Many of these elves have beards.
• Perpetual Frowner: Agnes is the toughest of the warriors and never smiles.
• Proud Warrior Race Guy: They have adopted a system based much more around ritual combat than paperwork.
• Violent Glaswegian: They've all got Scottish accents, and tempers to match.

Magical Creatures

Introduced in Season 1

Wood Man

Voiced by: Ako Mitchell
"Sometimes it's better to retrace old steps than it is to forge new paths."

A strange humanoid made out of wood that comes and goes from Hilda's house as he pleases. Although not harmful, he is pretty unpleasant.

---

• Adaptational Jerkass: While both the cartoon and the books have the Wood Man walking into Hilda's house, in the former he's a bit more rude, making snide remarks and slamming the door in Hilda's face. In the graphic novel, he was much calmer, quieter and more polite.
• All There in the Manual: Hilda's Book of Beasts and Spirits reveals significantly more information about his species than the show ever does. Among other things, not only is his habit of entering human homes uninvited with firewood standard protocol for his species, but there are entire communities of wood people like him living beyond the show's setting.
• Arboreal Abode: He lives in a two story house build around, and inside, a hollow tree.
• Blue-and-Orange Morality: Possibly. He brings Hilda and her mother plenty of firewood, but never knocks, makes himself at home (though he'll leave when told), and is pretty standoffish. He'll also help Hilda in a very roundabout way but in his own time and on his own terms, and reveals at the end of Season 1 that he considers Hilda a very dear friend despite never being very nice or polite to her.
• Brutal Honesty: Couldn't care less what Hilda or anyone else thinks of him.
• Burn the Witch!: After he was roped into another one of Hilda's adventures (an accidental trip into the past), the villagers almost burned him for being a "demon" (they mistook him for one because of his head floating above his body without any neck).
• Deadpan Snarker: And how. Nearly every line of his seems to be some sort of sarcastic aside, as a result of his Brutal Honesty and expressionless face making it hard to tell exactly how honest he's being.
• A Dog Named "Dog": Wood Man's species are known as Wood Folk, according to Hilda's Book of Beasts and Spirits.
• Exact Words: When he steals from the Draugen in Season 2. Hilda says she thought they were going to help the Draugen. Woodman points out that SHE said they were going to help them, HE only said they were going to find them.
• Frozen Face: Being made of wood, his face never changes and his expressions are totally unreadable. His mouth doesn't even move when he talks.
• Jerk with a Heart of Gold: He's not very nice or polite, but he is capable of showing he cares.
• Losing Your Head: His head already floats inexplicably above his body, but "The Beast of Cauldron Island" shows that he can survive getting his head and body completely separated.
• Lost Him in a Card Game: With Hilda.
• Lovable Rogue: He frequently robs scattered magical creatures for the sake of adding some flavor to his living room, but he does it with such a laidback demeanor, its hard to begrudge him.
• Manipulative Bastard: He loses Hilda in a card game, but on purpose so that Hilda would be taken to a giants lair where some of Wood Man's stuff was. If he's to be believed, he also purposefully lost his rope ladder at least weeks ago in preparation.
• Mr. Exposition: Played with. When he appears, he'll often provide Hilda with useful information about various creatures she's dealing with. However, he tends to leave out important details, particularly when his motives for encountering these creatures conflicts with Hilda's reasons. He'll also refuse to explain things if he finds it too tedious.
  Wood Man: Explaining things isn't my forte.
• Non-Answer: When "reclaiming" a crown from the forest giant:
  Hilda: You lost that crown?
  Wood Man: I would prefer not to lie to you.
• No-Neck Chump: Literally; he lacks any semblance of a neck and his head just sort of levitates above his torso as a result, and yet he can eat, drink and speak just fine, being supernatural.. No explanation is given in any of the official Hilda media. An unofficial comic on Luke Pearson's DeviantArt account however shows his head literally detaching after he laughed too hard when Hilda tickled him.
• An Odd Place to Sleep: When Hilda remarks that they may need to stop for the night soon, he lays down on the forest floor.
• Pet the Dog: For all his prickly behavior, he gives Hilda a nice speech about how you never really leave your homes behind and encourages her to visit — even saying that she's a friend to him.
• Plant Person: He's some kind of humanoid plant creature whatever he is. He might be based on the Green Man or the Woodwose, two common figures in European folklore associated with the forest and plant life.
• Running Gag: Walking into people's homes without knocking.
• Shout-Out: He shares a significant similarity in design to the Dekus from The Legend of Zelda.
• The Thing That Would Not Leave: Averted. While he has a habit of letting himself into Hilda's house, he only ever seems to stay long enough to warm himself by the fire. Neither Hilda nor Johanna really mind; they just wish he would knock first.

Jorgen

"It has been a long time since I was here."

The last giant in the valley. After a long time of watching over the world from the highest mountain, he is now looking for a friend who promised to meet with him.

---

• Attack of the 50-Foot Whatever: He's an ancient giant, much bigger than modern giants, and can stomp over Hilda's house easily.
• Gentle Giant: Despite his size and overall creepiness factor, Jorgen is very sweet to Hilda and even saves her life near the end of Midnight Giant.
• History Repeats: Discussed. The ancient giants once populated the earth, but when humans arrived and resented the giants for accidentally stepping on their homes all the time, eventually it became clear the world had become too small for them and they left. As Jorgan and his girlfriend leave and accidentally step on Hilda and her mum's house in the process, Hilda realizes how the elves feel with her and her mum stepping on their houses all the time too, realizes the valley is no longer a place for them either, and they leave for Trolberg.
• In a Single Bound: At the end of "The Midnight Giant", he and his beloved jump off the planet together into space. According to Wood Man, this was a way that the giants moved away.
• I Will Wait for You: Agreed to meet his girlfriend in the valley where Hilda and her mum live at midnight four thousand years ago. Even though his love seemingly didn't show, he's been coming back every midnight since.
• Last of His Kind: Returns to the valley after thousands of years to find that his friends have gone.
• Our Giants Are Bigger: Jorgen is of an ancient race driven from the earth ages ago, who are significantly bigger than the Forest Giants that still live on Earth.
• Put on a Bus: At the end of "Midnight Giant", he and his girlfriend, having found each other, decide to leave to find the other ancient giants. As Wood Man predicted, they take a big jump and leave Earth to space.
• Rock Monster: While it's difficult to tell with his fur, his ears and nose are composed of stone.
• Shout-Out: His design is reminiscent of the various Colossi in Shadow of the Colossus, especially Gaius, with his incredible height, covering of fur, tiny blue eyes, and stone nose/mouth. The way Hilda uses said hair to climb him, as one does in Shadow of the Colossus, only makes the similarity that much more uncanny.
• Stealthy Colossus: He is quite silent while moving, and can disappear from Hilda's field of vision as soon as she gets distracted.

Illus

Jorgen's girlfriend, who waited for him for 4000 years but fell asleep and became a mountain.

---

• All There in the Manual: Her name is not stated anywhere in the graphic novel Hilda and the Midnight Giant, the animated series or the tie-in novel Hilda and the Hidden People. That the graphic novel does not mention her name is all the more remarkable since "Hilda and the Midnight Giant" does feature a two-page information section that depicts 20 of the ancient giants, including Jorgen, with their names and a brief biography. Her name was finally revealed in the book Hilda's Book of Beasts and Spirits.
• Gentle Giant: Like Jorgen and the other giants, Illus means no harm towards anybody smaller than her, even despite the trouble she can inadvertently cause with her titanic size. Hilda describes her in "Hilda's Book of Beasts and Spirits" as being a kind and patient individual.
• In a Single Bound: At the end of "The Midnight Giant", she and Jorgen jump off the planet together into space.
• I Will Wait for You: She waited 4000 for Jorgen's guard duty to be over so they could be together again.
• Mistaken Identity: An interesting case where not an in-universe character, but the readers of the comic are guilty of this trope; since Illus' strongly resembles Valfreyja, at least in the graphic novel where they both have the same conical shaped body, combined with the fact that the graphic novel does not list Illus as a seperate giant, led many readers to believe that Illus was in fact Valfreyja, until "Hilda's Book of Beasts and Spirits" corrected this misconception. This mistake may have contributed to Valfreyja being given a redesign when she appeared in Season 3 of the series.
• Our Giants Are Bigger: Like Jorgen, she's one of the last of a race of colossal, primordial beings that shaped the world in ages past and were eventually forced to leave due to the spread of humans.
• Rock Monster: She resembles a humanoid mountain.
• That's No Moon: She fell asleep at some point after sitting down in the valley, and over the centuries that followed her body slowly became a mountain covered in earth, snow and plants. Hilda never knew the mountain next to her house was actually a giant and only found out after accidentally waking up Illus.

Woffs

Round, furry canine creatures that are typically seen flying above Trolberg and Hilda's old mountain home in large flocks. Their migration patterns are a mystery to those who attempt to study them.

---

• All There in the Manual: Hilda's Book of Beasts and Spirits mentions that people in the show's setting believe Woffs to have been born from the beard of the giant Har. This is jossed in-universe in Season 3, where it is revealed that Woffs, alongside most of the show's magical creatures, originated from the Fairy Isle.
• Catch a Falling Star: Multiple times now when Hilda falls from a great height her fall usually gets broken by a nearby flight of Woffs.
• Cephalothorax: Woff bodies are composed primarily of their heads and a tail with no visible limbs.
• Flipping Helpless: If Woffs land upside down, they are unable to get back up into the air under their own power. In "The Old Bells of Trolberg," the automated bell system disrupts an entire flock's flying pattern and they require the help of the Sparrow Scouts to return to the sky.
• Flying Face: Again, Woffs are floating faces.
• Giant Flyer: They're shown to be large enough to carry humans on their back and cause significant damage if they collide with a large structure or flying vehicle.
• Ridiculously Cute Critter: It's hard not to find these giant flying fuzzballs very adorable.
• Whale Egg: They lay eggs despite resembling canines. Their eggs are covered in fur.
• White Wolves Are Special: Technically not a wolf, but Woffs are canine in nature. White Woffs are rare and, according to a divinatory text Frida was reading, are also said to be a sign of good luck and that magic is more powerful in the lunar cycle during which they are spotted.

The Great Raven

Click here to see his true form^note 

Voiced by: Cory English

A giant Thunderbird that long ago was mistaken by Trolberg’s ancestries to be a sign of good luck from the Gods, resulting in him becoming a local legend among the town.

---

• Artistic License – Animal Care: He's shown drinking hot cocoa in Episode 10, despite chocolate being poisonous to birds. Possibly justified in that he's supernatural.
• Back for the Finale: He makes his triumphant return in the epilogue of the final episode, returning to Trolberg yet again for the yearly Bird Parade. He even allows Hilda to ride on his back again.
• Beware the Silly Ones: The Raven himself has some Cloudcuckoolander moments, being a spirit and all. Be that as it may, he will fight ferociously to protect his friends, and can easily hold his own against the Forest Giant.
• Civilized Animal: He is a raven/thunderbird and while he mostly acts like a bird, beyond his ability to talk to humans, he does occasionally show some human behavior, which is best exemplified in "The Storm", where he is shown sitting on Hilda's sofa wearing a bathrobe while eating pie and drinking cocoa like a human, with a later scene showing him drinking coffee.
• Dark Is Not Evil: He is a giant black raven, but is overall very nice and helpful to Hilda, and one of her most recurring allies.
• Deadpan Snarker: Is shown to have shades of this in Episode 10, mostly in part to Victoria's shady behavior.
• Delayed "Oh, Crap!": When he's explaining to Alfur what cats are, he's more interested in the fact he remembers them than the danger they represent.
• Easy Amnesia: All it took to make him completely forget who or what he is, was a stone to the head. And all it takes for him to regain his memories is seeing a newspaper article about the Bird Parade (graphic novels)/Hilda telling him who he is (Animated series). In the novelization, it takes a bit more effort, with Hilda giving him blue nettle to stimulate his brain.
• Fake Ultimate Hero: The people of Trolberg believe he is a messenger of the Gods that bestows good luck during the Bird Parade. Raven insists its just a coincidence but feels obligated to go to the parade each year to keep up morale.
• Feather Fingers: His wing feathers sometimes function as fingers.
• Giant Flyer: His "Great Raven" form, which has a comparable size to the largest pterosaurs.
• Identity Amnesia: "The Bird Parade" narrates the fact that he has fully forgotten who he is, except for a few snipets of information. Hilda tries to bring his memories back.
• Leaning on the Fourth Wall: When Raven forgets how to fly due to amnesia, he believes he can't walk because he has these tiny stick feet. Alfur points out that he has stick feet too and he can walk just fine.
• Misplaced Accent: He speaks with an American accent, probably because he's from Native American mythology.
• Misplaced Wildlife: A mythical example. The Thunderbird is a creature from Native American legends, yet he lives in Scandanavia for some reason. Then again, he can fly.
• Mistaken Identity: He was mistaken for one of Odin's messenger ravens by the first settlers of Trolburg, but made a point of returning each year when he noticed how happy him doing so made the people.
• Mouthy Bird: His beak looks more like a snout and he has teeth.
• Put on a Bus: Save for a cameo on a picture in "The Replacement", he sits out the entirety of Season 2. There is a deleted scene from the first episode where he briefly appears, only to announce he's leaving Trolberg for a while and telling Hilda he'll see her at next year's parade. This means he is effectively Adapted Out of "Hilda and the Stone Forest", as he played a major role in the comic.
• Running Gag: He can't remember Hilda's name and refers to her by several wrong names during "The Bird Parade".
• Shock and Awe: He's a thunderbird and is capable of shooting lightning.
• Sizeshifter: He can change sizes between the huge "Great Raven", which is implied to be his true form, and taking the form of a small raven that he uses for his everyday life.
• Thunderbird: His true form, normally hidden by his sizeshifting. He can speak and shoot lightning from his wings, and at his full size he's big enough to carry at least two human children on his back. The citizens of Trolberg mistakingly believe him to be the messenger of a god worshipped in older times, and that he brings good luck.
• Toothy Bird: Not only does he show teeth, but his beak is drawn as looking more like a snout.
• Unexplained Accent: He speaks with a distinctly American dialect despite having lived in the decidedly-not-American Trolberg for who knows how long.

Vittra

A species of subterranean plant creatures that hibernate near the ground once a year to catch sunlight.

---

• Ascended Extra: In the comics, a single vittra has a brief scene in "Hilda and the Black Hound" that is part of a montage of Hilda trying and failing to earn Sparrow Scout badges, and a few of them make a cameo on a single panel in "Hilda and the Stone Forest". In the show they get a whole episode devoted to them, in particular the Vittra Hilda accidently wakes up.
• Deep Sleep: It's remarked that not much can wake a sleeping Vittra. The one that Hilda and her friends encounter only wakes up because they accidentally drove a stake into his head.
• Early-Bird Cameo: The Vittra's first appearance was in a montage in The Stone Forest.
• Jerkass: The Vittra that wakes up and attacks the Sparrow Scouts is verbally abusive and rude. More than a little justified because they took most of his friends away to be mulched. What isn't justified is his being rude to a random Vittra child who comes up to him.
• Jerkass Has a Point: Despite his general unpleasant demeanor, the Vittra that fights Frida correctly points out that his friends could have been killed by her actions, even if she didn't know what she was doing.
• Jerkass to One: The main Vittra is not a Nice Guy to begin with but his worst insults are usually, if not, only aimed towards Frida.
• Meaningful Name: Vittra are Swedish nature spirits who live underground, farming herds of magic cattle and taking grave offense at humans building over their homes. Elements of their mythological origins are alluded to in the show, such as the unexplained appearance of a herd of miniature cows living in the vittra tunnels.
• No Celebrities Were Harmed: The main Vittra Hilda interacts with has a voice like Gilbert Gottfried.
• No Indoor Voice: The Vittra that the Sparrow Scouts almost never talks in a calm voice. Instead, rudely shouts nearly all the time.
• Plant Person: They're basically root people with a single plant on their heads that stick out of the ground during hibernation to collect sunlight via photosynthesis.
• Signature Scent: Vittra have a distinct stench compared to moldy onions and rotten turnip.
• Underground City: The Vittra live in one, though it's really more of a burrow or a Tunnel Network than a city.

Rat King

An entity composed of multiple talking rats. It is addicted to secrets and willingly trade secrets with anyone.

---

• Absurdly Spacious Sewer: Makes their home in one.
• Canon Foreigner: While the Rat King is mentioned in "Hilda and the Bird Parade", he does not actually appear in that story or any of the other comics. The closest thing we get there is 3 white mice whose shadows Hilda and Raven mistake for the Rat King.
• Dark Is Not Evil: A giant black mass of rats with glowing red eyes, who just loves trading secrets.
• Gossipy Hens: A whole host of them.
• Hive Mind: They appear to be this. Either that, or they are incredibly coordinated.
• Knowledge Broker: Acts as one for the city of Trolberg, sharing secrets with anyone willing to trade.
• Rat King: Exactly What It Says on the Tin
• Red Eyes, Take Warning: Subverted. The kids are terrified when a black mass of rats with thousands of glowing red eyes approach them in the dark, but it turns out the Rat King just wants to trade juicy secrets.
• Voice of the Legion: All the rats talk as one.
• Wild Card: The Rat King is neither good nor evil, it merely likes to trade in secrets and will do so with anyone. He had helped both Hilda and the Marra during "The Nightmare Spirit".
• The Worm That Walks: The Rat King is a sentient colony of rats that speak and move as one entity
• You Dirty Rat!: Subverted. While it's a mass made up of talking rats, it just likes to trade secrets with anyone.

The Marra

A spirit that takes the form of a teenage girl and gives David nightmares.

---

• Always Chaotic Evil: Unlike Trolberg's other supernatural residents, they're seemingly the only ones who are consciously and joyfully evil, and there isn't shown to be a single good Marra in the group. In the novelization, Hilda actually counted on the Marra to be another Non-Malicious Monster who didn't know how much misery she was causing, and was quite shocked to learn about the Marra's true nature.
• Always Female: The Marra always look like teenage girls.
• Ambiguously Human: The Marra look human enough, but they can turn into black smoke at will, their eyes glow while using their powers, they can turn dreams into nightmares, and they feed off the fear felt from said nightmares. This trope, in fact, is a pretty big factor for the trope underneath.
• Ambiguous Situation: Are the Marra teenage girls with special powers, or are they spirits that just look like teenagers? There's plenty of evidence for both: while the book that Hilda finds in the library says they are spirits, the Marras themselves imply they can turn Frida into one of them. In a later episode, one of them is shown to live like a normal teenage girl during the morning and even has apparently normal parents.
• Bad Powers, Bad People: They are Nightmare Weavers with an array of other unpleasent powers, and they're nasty pieces of work when they show their true colors.
• The Bully: Once they find a suitable victim, they'll turn their dreams into nightmares and feed off their fear without a second thought.
• Canon Foreigner: They do not appear in any of the graphic novels, and are exclusive to the Netflix series.
• The Corrupter: While it's not clear if they can actually turn someone into a Marra, they still convince Frida to join their circle in hopes of turning her into one of them.
• Dream Weaver: They can turn people's dreams into nightmares.
• Emotion Eater: It's implied they feed on the fear their nightmares cause, as seen when Frida attends a meeting and a marra that's sharing a story about her latest nightmare victim emits glowing green plasma that the others consume.
• Fair-Weather Friend: They allow Frida into their circle, but throw her to the wolves the second things start going badly.
• Glowing Eyes of Doom: When using their powers, their eyes glow green.
• Green and Mean: Although the girls look normal, all of their powers are green colored and even their eyes glow green when using their powers, and they are some of, if not the, most malicious beings that Hilda faces off against.
• Humanoid Abomination: They resemble teenage girls, but can turn into black smoke, their eyes glow, and their modus operandi involves giving people's nightmares in order to feed off their fear.
• It Amused Me: Part of the reason they enjoy giving people nightmares, besides to eat from their fear, is because it's just so fun for them. This is the reason why the Marra that was bothering David decides to leave him and Hilda alone: because the latter isn't as fun since she's asking for the nightmares.
• Jerkass: Beyond the fact they get their powers from terrorizing others in their sleep, they're generally pretty unpleasant.
• Lack of Empathy: Once a Marra decides to give you nightmares, your mental health and etc. won't mean squat to them.
• Logical Weakness: The Marra might be masters of giving people nightmares, but they can only do this if the person in question is asleep. If the person is awake, the most they can do is wait for the window of opportunity to open again.
• Meaningful Name: "Marra" seemingly comes from "Mare," a Germanic creature said to give people nightmares, which describes the Marra's MO pretty well.
• Mind Rape: They are capable of giving unsuspecting victims horriffic nightmares.
• Nightmare Weaver: Their specialty: as long as they know what a person fears, they can turn even the nicest of dreams into an absolute nightmare.
• No Name Given: Aside from Kelly, none of the Marra are named, including the twin-tailed one who first appears and is the character image.
• Not So Above It All: We briefly see a softer side of Kelly when her mother is about to donate her old stuffed animal.
• Peek-a-Bogeyman: While the Marra take great pleasure in giving nightmares to people so they can feed on their fear, at least they do not do anything to physically harm their victim.
• Sleep Paralysis Creature: They are spirits who cause nightmares at night to feed off people's fear, and a picture shown in the book telling about them shows a Marra sitting on a man's chest, similar to how the folkloric creature they were inspired by are usually depicted.
• The Sociopath: They walk among normal humans during the day, but once night comes, they invade someone's home to give them nightmares so they can feed off their fear, with their preferred people being those who give no resistance. And as shown with Frida, they'll only become friends with you if they can get something out of you, and they'll ditch you to fend for yourself without bathing an eye.
• Spider Swarm: The Marra in the character image summons one early on in Hilda's dream, in an unsuccessful attempt to prey on a basic fear.
• Super-Empowering: They imply that they can turn others into Marra. Whether they can actually do this or they just said that to catch Frida's interest isn't made clear.
• Super Smoke: Marra can turn into wisps of smoke, which they usually use to slip into keyholes or other small spaces.
• Our Spirits Are Different: They're at least called spirits in the book they're mentioned, and they take the form of teenage girls who feed off the fear from nightmares they give to people.
• Teens Are Monsters: They look like teen girls, and their favorite activity is to find some unlucky person to turn their dreams into nightmares so they can feed off their fear.
• Toxic Friend Influence: Their relationship with Frida, which is clearly built on peer pressure, with the ultimate goal of making her another Marra.
• They Look Just Like Everyone Else!: Unlike basically every other magical creature, both in and out of Trolberg, the Marra don't stand out from humans whatsoever. Even when they show their true colors at night, they remain humanoid, only gaining Glowing Eyes of Doom and an array of supernatural powers.
• Was Once a Man: It's implied the Marra were all ordinary girls at one point before being transformed into malevolent spirits.
• Weaksauce Weakness: They can be rendered more or less powerless by a leather belt.
• Weaker in the Real World: While in a person's dreamworld, there's next to nothing a Marra can't do, but during the day, while acting like normal teenagers, the most they can do is their Super Smoke powers to get around.

Water Spirit

A spirit made out of water. It can lead people through bodies of water.

---

• Blow That Horn: Alfur uses a conch shell (or rather, he has Hilda use it for him) to summon the water spirit.
• Nature Spirit: Living masses of water found wherever water is found.
• Our Spirits Are Different: Naturally. According to Hilda's Book of Beasts and Spirits, they come in freshwater and saltwater variants, although the latter have been known to go upstream.
• The Voiceless: In the graphic novels and animated series. Averted in the novelization.
• Walk on Water: While being made of water, it can carry people on its body.

Lindworm

A species of anti-social dragon that fled from the area during the city's construction. Their fire can null any elf's contract. The last one of them nearby lives on a small island in the city's coast and cares for her garden.

---

• All There in the Manual: Hilda and the Midnight Giant briefly mentions that dragons like her are descended from the giant Fjallmar (as are horses in the show's universe!).
• Ambiguous Situation: The lindworm that Hilda and Frida meet says that she has social anxiety. It's ambiguous whether the entire species has a degree of this and thus is so anti-social or if that's her own private trait.
• Canon Foreigner: She does not appear in any of the graphic novels and is exclusive to the series (although there is mention made of dragons existing in the setting in Hilda and the Midnight Giant).
• Caring Gardener: Downplayed. She was incredibly angry and was even willing to eat Frida and Hilda, but once she was shown city flowers, she backed down and was incredibly kind and polite to them.
• Cue the Flying Pigs: Alfur claims that the "null if burned by a lindworm" clause in elf contracts is equivalent to "when cows fly."
  Frida: Don't you mean when pigs fly?
  Alfur: No, that happens with surprising regularity.
• Blood Knight: By her own words, she never backs down from a fight.
• Dragon Hoard: Discussed. The Lindworm prefers the treasures of the earth to silver and gold. Her hoard is not a pile of treasure, but her garden.
• Disproportionate Retribution: Her response to being woken up to burn some paperwork? Devouring the children who arouse her from her slumber.
• Fighting Irish: Has a heavy Gaelic accent, and is quite the hot head.
• Know When to Fold 'Em: Refuses to even attempt to fight the Kraken when it emerges, opting instead to get everyone off its back.
• Non-Indicative Name: Despite the name Lindworm, they are actually a kind of dragon. Frida lampshades that she was expecting to find some sort of small worm. ^note It's actually spot-on, if you understand Celtic languages or Middle English. Most fantasy fans would notice it right away if it used the modern spelling of lindwyrm.
• Our Dragons Are Different: She resembles the most common depiction of a lindworm, namely having a serpentine body and no hind legs.
• Playing with Fire: They're capable of releasing fire at will. Elf contracts have a special clause to be null if they are to ever be burnt by that fire.
• Technicolor Fire: The fire the species release are blue.
• Would Hurt a Child: Angry out of her mind with another group coming by to try to get away from an elf's contract, she threatens to eat Frida and Hilda and make them an example.

Tide Mice

Magical mice summoned by witches for people to grant them good luck, but eventually take the people's souls and give them to the witch.

---

• Curse Escape Clause: The tide mice enchantment comes with a 30 day trial period in which the enchanter can still decide to return the enchanted tide mice, and not get the souls of the people the tide mice were given to. This is a very good thing, given how liable they are to be conjured by novices unaware of the danger they pose. That said, the instructions are in such small print that even Alfur struggles to read them.
• Eek, a Mouse!!: They cause panic among the entire audience at the Warbler concert once they become visible to everybody.
• Exact Words: The instructions for breaking the enchantment says don't forget to feed the disenchanted tide mice a morsel of bread, or they will never leave you in peace. Not to remember to feed them, but specifically explains not to forget. Though Hilda ultimately remembers to feed them bread, she admits that she forgot the step for a minute. The act of forgetting results in them following her home and eventually taking over a snack food company in Season 2's "The Jorts Incident".
• Explosive Breeder: In "The Jorts Incident", they find numerous hosts (the employees of the snack food company) and multiply rapidly as a result. Hilda and her friends end up having to use vacuum cleaners to capture all the mice.
• Glowing Eyes: They have these. As time goes on, the people who were given the mice also develop these periodically, as does the enchanter.
• Invisible to Normals: Until the ritual for breaking the enchantment is initiated, the mice are invisible to everybody except the enchanter.
• Killer Rabbit: When they're not sucking people's souls out, they seem to be nothing more than adorable little mice.
• Ritual Magic: They are summoned using a magical ritual.

Ghosts

Ghosts of deceased humans that can be awoken by a ritual, but can also come out at night of their own accord.

---

• Animate Dead: How they are most commonly encountered. Interestingly, once one has been summoned they can wake up other ghosts themselves.
• Celestial Deadline: Must return to their graves before sunrise.
• Creepy Cemetery: Most commonly found in one, naturally.
• Dem Bones: Have shades of this due to containing the remains of their skeletons from when they were alive.
• Detachment Combat: Able to do this with parts of their skeletons.
• Flight: Seem to be capable of it.
• Fog Feet: Played with, they appear to sometimes have these but they usually have distinct legs.
• Ghostly Glide: Generally prefer this to walking, but they alternate.
• Intangibility: Can pass through walls and other objects. Interestingly this does not apply to their bones.
• Our Ghosts Are Different: Ghosts with blue spectral bodies that still contain their skeletons which they can move independently, settle their disputes with wrestling, and must return their bones to their graves before sunrise.
• Rise from Your Grave: How they tend to emerge when awakened.
• Weakened by the Light: They have to return to their graves by sunrise or else they will be destroyed.
• Wrestler in All of Us: Apparently they resolve most disputes with a wrestling match.

Weather Spirits

Spirits that control the weather and are shaped like clouds. They like debating over anything and once many get together, they create an unprecedented storm.

---

• Ascended Extra: In the graphic novels, they only get 2 cameos of one panel each. In the series, they are the driving force behind the events in "Chapter 10", and get more development as characters.
• Attention Deficit... Ooh, Shiny!: They got distracted on their way to Victoria Van Gale by getting into a huge argument with each other, and during said argument they'd frequently get so angry they forget whatever point they were trying to make. (And it turns out the reason they were going there in the first place was because she kidnapped a young weather spirit.)
• Cumulonemesis: They are living, sentient clouds, and can get quite violent if provoked, causing severe storms.
• Does This Remind You of Anything?: They're essentially a comment section or a thread on an internet chatroom when fighting. They're constantly at each other throats, to the point some have even forgotten the point they were trying to make. Hilda calls herself their moderator when she finally goes to try to alleviate the situation.
• Nature Spirit: Like water spirits, they are supernatural entities associated with a natural element, in this case, the weather.
• Our Spirits Are Different: Compared to water spirits, they're depicted as fully capable of speaking and are overall much more like anthropomorphized clouds.
• Skewed Priorities: Got distracted rushing to rescue a wind spirit child to get into a huge (and petty) argument with each other.
• Solid Clouds: They either are this when they want to be, or when Toon Physics are being Played for Drama. Hilda is able to climb to the top of one before promptly falling right through.
• Weather Manipulation: Or rather, they are the weather. Regardless they have clear and total control over the snows, the winds, and the storms.

Forest Giants

The closest living relatives of the ancient giants (Jorgen and his ilk). They are much smaller than their long-gone kin, being "only" as tall as very large trees.

---

• Ascended Extra: In the books, only a single forest giant appears for a quick gag in the very first book. The series still features only one individual, but he's a secondary antagonist in the plot of his episode, with the show also fleshing them out some more.
• Attack of the 50-Foot Whatever: Forest giants are considered tiny by giant standards, but are still far larger than most creatures living in the world today.
• Berserk Button: Being reminded of how comparatively small they are compared to the giants of old is an easy way to set them off.
• Early-Bird Cameo: In the animated series, one appears during a nightmare inflicted on Hilda by the Marra, but they don't make a proper physical appearance until a few episodes after.
• Horned Humanoid: They have large antlers.
• Jerkass: The one forest giant Hilda does encounter is very rude and ill-tempered.
• Our Giants Are Bigger: They're the smallest of all giants, reaching only the height of a very big tree when compared to their mountain-sized brethren of ages past. Unlike the ancient giants, they're treated more as a species than a collection of related individuals.
• Stealthy Colossus: The one Hilda encounters goes completely unnoticed by her until Wood Man and the elves point out its presence to her despite the giant standing literally right behind her. The giant actually takes great offense at this, seeing it as a reminder of his relative smallness for a giant.

The House in the Woods

A mysterious, sentient house. It wants the people who get inside it to never leave and for that, creates whatever they desire. It also can morph into a confusing labyrinth to make sure that the people inside it never leave.

---

• Ambiguously Evil: The house is unwilling to let anyone leave at first and creates a maze to keep Hilda and Wood Man from finding an exit, but it keeps them well and healthy as much as it can and when Hilda asks for it, releases them. It's not clear whether it is just a lonely being trying to have someone to care for and gives up when Hilda refuses to be that someone or was trying to keep them prisoners and Hilda found a loophole by asking to go back home and the house had to give it to her.
• Bigger on the Inside: In the default state the interior and exterior dimensions match, but the House can easily increase its internal dimensions as it sees fit.
• Bizarrchitecture: The interior briefly becomes this when Hilda and the Wood Man realize something is wrong.
• Canon Foreigner: The house does not appear in any of the graphic novels and is exclusive to the series.
• Genius Loci: The house is aware of everything happening inside it and can change its insides freely.
• Gilded Cage: The house offers to whoever is inside whatever they want and satisfies their every desire, but it will fight to keep them there and not let them leave.
• Outside-Context Problem: The cabin is as of yet the only episode focus that isn't explicitly stated to be a spirit of some kind, and it's not even clear what it really is. This is never touched upon by the time Hilda is back home and the episode is over.
• Scooby-Dooby Doors: When the Wood Man tries to escape via the window, he falls down the chimney, into the same room he just left.
• Telepathy: The house seems to be able to read the victim's mind, as it is able to put pictures of Hilda and Wood Man's relatives and favorite objects onto one of the corridor's wall while they're trying to escape the labyrinth that the house created for them.
• Wishplosion: Hilda manages to escape the house by having everyone in it wish for as much as possible as quickly as they can think of it, before wishing to go home, opening a portal to her apartment in Trolberg. However, it's left unclear whether the house was left too overwhelmed by the wishes to realize it was setting them free, or if it just decided that it wasn't worth the trouble of keeping them.
• Yandere: Not of a romantic type; it wants to have someone living inside it and will cater to their every wish, but the problem is that once it has Hilda and her friends it is adamant on not letting them go. It's not known if it wanted the company or something more sinister.

Nisse

Gnome-like creatures that live in the negative spaces of houses. There is one for each house and they're very territorial.

---

• All There in the Manual: Hilda and the Midnight Giant briefly mentions that Nisse are related to Trolls through sharing ancestry in the giant Bjorg (who shares the furry body, oversized nose, and animal-like tail of all nisse).
• Dangerous Forbidden Technique: For Nisse it's going into the Nowhere Space of the outside. It's so huge you will probably never get out and even if you do there's no telling where you might end up.
• Does This Remind You of Anything?: They are essentially treated as homeless people by the people of Trolberg, and the ones that are homeless are essentially a thinly veiled metaphor for the issue.
• The Faceless: With the exception of Hilda's nisse, every individual seen has their face completely concealed under a massive amount of hair.
• Fantastic Racism: They are generally believed to be thieves and people had been kicking them out of their houses recently.
• Gag Nose: Almost all the nisse seen only have their giant schnoz visible from underneath their furry faces,
• House Fey: They live unseen in every house, doing small favours for the people who live there and snatching up lost or discarded items. They're bound to obey the owners of the house when asked to leave. In season 2, Joanna and her house Nisse have become closer, and Tontu stores some of her stuff on his hammerspace, which frees up space and helps keep the house clean.
• Insistent Terminology: Nisse claim to not "steal" from the outside world, but "borrow", even if they don't exactly give the stuff they borrow back.
• Loners Are Freaks: Most Nisse live alone in a single house, and most humans tend to distrust the Nisse they find.
• My Species Doth Protest Too Much: Strange as it sounds, this seems to be a hat for the Nisse. They are so territorial and solitary that they automatically assume that all other Nisse are liars and cheats, and that they a Token Heroic Orc.
• Planet of Steves: They are all named Tontu. Also (nearly) an instance of A Dog Named "Dog" - tonttu is Finnish for elf or gnome.
• Pocket Dimension: They nest in one made of the sum total of unused space in a building known as a Nowhere Space. They can enter and leave it from wherever the unused space starts like underneath furniture or spots on shelves that can't be reached or seen.
• Sadly Mythtaken: While the depiction of them as territorial house fey is accurate, visually they have almost nothing in common with Scandivanian Nisses, who are usually depicted as diminutive elderly humans with white beards and long red caps, wearing wool clothes.
• Took a Level in Jerkass: "The Nisse" has already shown that these guys don't like each others company as they will attack each other onsight. By "Strange Frequencies" however, they get worse. With Frida's nisse stealing Frida's book a second time, that same nisse dragging Frida along with her, and the other nisse not only stealing from each other but also getting more violent with each other in the meeting. To make matters worse, they attack the Raven Leader just because the latter had a good sash on her. It's only when the lending library is made the nisse start to get along.
• What Happened to the Mouse?: The Nisse Hilda befriended gets a new home, but what about all the other homeless Nisse?

The Black Hound

A gigantic beast also known as a 'Barghest', that takes the shape of a big black dog. It starts to scare the city as soon as it appears.

---

• Adaptational Late Appearance: In the graphic novel, he makes his debut in the same story where Hilda joins the Sparrow Scouts. Hilda and Johanna catch a glimpse of him while driving home after Hilda's initiation ceremony. In the series, he's absent in Episode 4 (which adapts Hilda joining the scouts), and doesn't properly appear till episode 12.
• Big Friendly Dog: Turns out to be this to his nisse owner. Hilda's Book of Beasts and Spirits says that this is not the case with all barghests though, and it ultimately depends on the nature of their upbringing.
• Canis Major: As the name implies, it is an enormous black dog that suddenly appears in Trolberg.
• Dark Is Not Evil: Despite being a large, terrifying-looking black creature, it ultimately turns out to be more or less a Big Friendly Dog.
• The Dreaded: His appearance at the city causes alarm.
• Final Boss: Subverted. It seems that the Black Hound is the final creature that must be dealt with before the season one ends and he is by far the most menacing-looking one. It turns out to just be a big lost dog and Hilda tries to free it to the wilderness.
• Fluffy the Terrible: His true name is revealed to be Jellybean. It's also revealed he is not evil at all.
• Getting Eaten Is Harmless: He did actually eat three people, but they appear to be none the worse for wear when he vomits them up.
• Gigantic Adults, Tiny Babies: A baby barghest is the size of a regular puppy, but as an adult, it can be big enough to fill a room.
• Glowing Eyes of Doom: Whenever it appears in darkness its eyes glow bright yellow, giving off a demonic appearance.
• Good All Along: The Black Hound is far from the beast many consider it to be. It ends up being more or less a giant puppy looking for its lost owner and when Hilda realizes this, she tries to release it.
• Hellhound: Based on the Barghest, a giant, demonic, black-furred hound from the folklore of Northern England considered to be an omen of death.
• Horrifying the Horror: Even the Marra are afraid of him.
• I Will Find You:He spent his entire life traversing the Nowhere Spaces trying to find his way back to his owner. By the time he finally found him, they were both fully grown.
• Misplaced Wildlife: Like the Great Raven, he's also a mythical example. Barghests are from Northern England, not Scandanavia.
• Secret Pet Plot: Part of his background story; he was secretly adopted as a pup by the Nisse living in Hilda's house, but when her parents found out they kicked him out.
• Stealthy Colossus: He has the ability to enter Nowhere Spaces, as he was taught by a Nisse before. As such, despite his size, he is able to show up and disappear just as quickly.
• Unwitting Instigator of Doom: Because he's so big he absolutely wrecks any room whose Nowhere Space he uses and is gone so quickly that any resident Nisse are wrongfully blamed and banished.
• Your Size May Vary: At his largest he appears to be the size of a small building, but in Chapter 13 he easily fits in the Scout Hall and the living room of Hilda's house.

Introduced in Season 2

Draugen

Spirits of sailors who died lost at sea who now crew a ghost ship off the coast of Trolberg.

---

• "Blind Idiot" Translation: In Norse folklore, these creatures usually only appeared one at a time, and was thus referred to as Draugen - "The Draug". The show uses "Draugen" as the name for the beings as a whole, despite it actually referring to an individual.
• Dem Bones: Have shades of this, due to containing the remains of their skeletons from when they were alive.
• Ghostly Glide: Seem to prefer this to walking, though they can do both.
• Ghost Pirate: A whole crew of them, no less!
• Ghost Ship: Reside upon and serve as the crew of one.
• Healthy in Heaven: Averted, several Draugen appear to have retained major injuries in their astral forms. One of them is even carrying his own head.
• No Ontological Inertia: When all the Draugen become normal ghosts and return to the afterlife with their loved ones, their ship collapses into a puddle of green ectoplasm.
• Ominous Fog: Enforced, they prefer to appear during appropriately spooky weather.
• Our Ghosts Are Different: Green ghosts that carry their skeletons around inside their astral forms, have glowing orange eyes and mouths, and are connected to a ghost ship that turns out to be entirely ectoplasmic in nature.
• Palette Swap: A greenish variation of the normal blue ghost design. This is significant: When the Draugen reunite with the ghosts of their loved ones, their green auras turn blue to signify they've become land-dwelling ghosts again.
• Skeleton Motif: There's a skull and crossbones painted on part of their ship, and the signal flare they shoot explodes into a skull shape. Justified by their skeletal appearence and pirate attributes.
• Running Gag: Nicholas' obsession with the rules and traditions of the Draugen, as well as Abigail's habit of drinking weird things.
• Unishment: Technically cursed to roam the seas forever, but they enjoy being immortal sailors so nobody minds. Subverted when they meet the ghosts of their loved ones, they choose to stay on land and become normal ghosts again.

Witches

The Council of Three

An entire society of witches living and working in the witches' tower under the library.

---

• Mage Species: Averted. In this setting, almost anyone can do magic; what sets witches apart from everyone else is that they are more about studying magic and obtaining knowledge. This ends up being the reason Hilda can't become a witch, she likes using magic sure, but sitting down and spending hours a day studying a single spell? No thank you.
• Running Gag: Their obsession with throwing people into voids.
• No Name Given: Abigail (the witch with the long hair), is the only witch of the Committee of Three named.
• The One Guy: Lloyd, the bass-playing gatekeeper of the Void of No Return, is this to the Witch’s Tower. It’s never stated whether he is a witch or some other kind of magic user, leaving open the question of whether only women and girls are allowed to study witchcraft.
• The Weird Sisters: The three witches that oversee their society fit this role.
• Your Makeup Is Running: Abigail has permanently running mascara.

Eldrid

A lava creature encountered in Tildy's maze. Apparently works as a landscaper.

---

• Good All Along: Is mistaken for a guardian monster by Hilda and Frida while Kaisa stays behind to "hold him off", but ultimately turns out to be friendly and only wanted to play board games.
• Living Lava: Underneath his "skin" appears to be molten lava.
• Mundane Utility: Apparently uses his fire powers to make sculptures for Tildy's ice garden.
• Rock Monster: Takes the appearance of a humanoid rock creature with glowing orange cracks.

The Void of No Return

A shadowy, tentacled monstrosity that lives in or might possibly be the void underneath the witches' tower under the library.

---

• Ambiguous Situation: Either lives inside of the void beneath the tower, or is the void itself.
• Canon Foreigner: It does not appear in the graphic novels and was created for the animated series.
• Cognizant Limbs: Appears to be composed of these.
• Dark Is Evil: A shadowy tentacle monster that lives in an endless void and eats people.
• The Dreaded: The threat of being thrown into its domain is a serious punishment for witches. The creature itself is feared by the Council of Three, motivating their desire to find any reason to throw someone into it.
• Eldritch Abomination: Mainly manifests as a multitude of giant shadowy tentacles ending in hands that feature an eye on the back and a mouth on the palm. We never see what these arms are attached to, if they're attached to anything.
• Eldritch Location: The void it resides in qualifies. Doubly so if the creature actually is the void itself.
• Fed to the Beast: Apparently a standard punishment in the witch world.
• Human Sacrifice: Seems to require these to be held at bay if the Council of Three's actions are any indication.
• Knight of Cerebus: So far one of the only threatening creatures in the series to be played completely straight and not possess a softer side or the capacity to be reasoned with. It also has an implied bodycount, and when it takes the witch responsible for opening the portal to its realm he is never seen again.
• Would Hurt a Child: Doesn't particularly care that two of the people thrown into it are children, it just wants to eat.

Viking Clans

Torgund's Clan

The Knudsen Clan

A pair of Viking clans that have spent years in a never-ending fight for an amulet, getting killed and revived every night.

---

• Action Girl: Both clans have 2 women among their ranks, and they are just as badass as their male teammates.
• All There in the Manual: The majority of the vikings go unnamed in the episode, in particular the ones in Knudsen's clan. Their names are however revealed on the official character sheet for the show.
• Death Is Cheap: Whenever they die, they are brought back to life by Sigurd.
• Deliberate Values Dissonance: Unlike the kids, they find it hilarious to learn that they were tricked into killing each other over and over.
• Fearless Fool: Whoever owns the amulet gains its power to lose all their fear. However, no longer having fear also makes them reckless and encourages them to adopt less strategic thinking, to the point their enemies can easily win (and it is implied that the team clan without the amulet is the winner more often than not) by simply employing tactics and strategy against their opponent. Sigurd downright says that he has no reason to want the amulet back because it makes the owner into an idiot.
• Forever War: The two clans were locked in an endless cycle of killing each other each day only to be brought back to life by Sigurd each night. The whole thing is an allusion to the einherjar of Valhalla, who fight to the death each day only to resurrect for more fighting tomorrow.
• Horny Vikings: Averted. They correctly do not wear the horned helmets stereotypical in fictional vikings.
• Power Glows: Their weapons glow. Interestingly enough, anyone who is injured by their weapons has their wounds glow.
• Proud Warrior Race: They're vikings, historically known to be an example of this trope in real life. They find all battle glorious, and consider it shameful to be resurrected from death by combat.
• Would Hurt a Child: In the midst of battle, one of the Knudsens tries to kill David before he touches the medallion. After he touches it, one of them decapitates him.
  • Played for Laughs with Torgund. In his case though it's well meaning. He offers to try the potion on Hilda and her friends, viewing it as fun. Since it involves getting killed though, they decline.

Sigurd

Hilda: Swamp Man! We need your help, Swamp Man!
Sigurd: It's Sigurd. You wouldn't like it if I called you flesh girl.

A swamp being that made the two Viking clans fight each other for eternity as revenge for stealing his amulet.

---

• All There in the Manual: Hilda's Book of Beasts and Spirits goes into more detail about what he is, revealing that there's actually a whole species of swamp monsters like him (although he's the only one of his kind in the region).
• Blue-and-Orange Morality: He finds it amusing to trap the Vikings in a perpetual cycle of dying and reviving every night for stealing his amulet, gets annoyed when the understandably unnerved Hilda and Frida tell him to stop and is only mildly exasperated when he has to behead David again to allow him to be revived properly after the girls put his head back on the wrong way around.
• Deadpan Snarker: "The face goes in front. It’s not that hard."
• Eyes Out of Sight: The moss-looking stuff on his head covers up his eyes, but he can see just fine.
• The Fair Folk: Whatever he is, he thought good payback for stealing something he doesn't even want was tricking the perpetrators into killing each other endlessly, as a prank.
• It Amused Me: The reason he keeps bringing the Vikings back to life.
• Lean and Mean: Subverted. He's quite tall and thin, and not to mention he continuously keeps the Viking clans fighting forever, but Hilda and Frida easily manage to talk him out of it. He seems like he's not really that bad of a guy.
• Named After Someone Famous: Sigurd was a legendary hero in Norse Mythology, known for slaying the dragon Fafnir.
• Swamp Monster: A tall, lean humanoid creature composed of swamp slime and muck. According to Hilda's Book of Beasts and Spirits, his species are known as "swamp men", and they are generally known for being practiced in healing magic.

Artificial Nisse

An animate doll-like construct that visually resembles a Nisse. Built by Victoria Van Gale to be her assistant.

---

• Back for the Finale: Victoria Van Gale keeps the thing's skull around with her in Fairy Country, and in the epilogue, it's shown to have been completely rebuilt.
• Creating Life: The end result of Victoria's attempt at this.
• Frankenstein's Monster: An allusion to this, as a cobbled-together creature built by a mad scientist.
• Old Magic: The spell used to animate it is explicitly stated to be this by Tontu.
• The Speechless: Doesn't have any physical anatomy that would allow for speech.
• Stalker without a Crush: Spies on David and Hilda through their bedroom window.
• Toy Disguise: Does this when Hilda and David first discover Victoria's secret room.

Krakens

Click here to see the mother^note 

Huge sea monsters that live in the bay of Trolberg. They awaken when the Safety Patrol rings an old underwater bell.

---

• Arrow Catch: The Mother Kraken grabs a harpoon Ahlberg shot at it out of the air and crushes it.
• Awakening the Sleeping Giant: What Ahlberg's bell did to them.
• Extra Eyes: They each have at least a dozen.
• He Was Right There All Along: Cauldron Island was the sleeping Mother Kraken's shell the entire time.
• Horrifying the Horror: The Lindworm and Lost Clan refuse to even humor the idea of fighting them.
• Kraken and Leviathan: The Kraken is an island-sized cephalopod-like sea-monster whose offspring eat the wood of wrecked ships.
• Monster Is a Mommy: The Kraken that lives under the island has several smaller offspring she feeds wrecked ships to.
• Non-Malicious Monster: The Kraken only sinks ships to feed the wood to its babies, and only fully emerges after getting shot with a harpoon. When Frida uses magic to tell them about the sunken wooden pirate ships further out in the ocean, they all head there instead of resuming their attack on the harbor, and one of the babies even returns Wood Man's body.
• Picky Eater: The baby Krakens only eat wood.
• That's No Moon: Cauldron Island is revealed to be the back of the monster itself.
• Turtle Island: The Mother Kraken is revealed to be Cauldron Island itself, her rocky shell making up its appearance.

Time Worm

A giant creature capable of freely traveling through time.

---

• Alternate Self: Exists only to consume and therefore erase these.
• Clock Roaches: Time worms exist to correct for temporal paradoxes by eating any temporal duplicates that wouldn't exist in new timelines.
• Hero Killer: Manages to eat two temporal duplicates of Hilda and Alfur, as well as nine Mr. Ostenfelds and one Tildy.
• Implacable Man: Can't be stopped by walls, furniture, or even its target travelling to a different time period. Even a freezing spell from an extremely powerful witch can't hold it for more than a couple minutes.
• Invincible Villain: Not necessarily evil, but the only way to save yourself from it requires sacrificing another timeline's duplicates to it.
• Knight of Cerebus: An unstoppable monster that kills multiple incarnations of the main character onscreen, and only leaves after erasing a version of the timeline where Tildy and Mr. Ostenfeld got to lead a happy life together.
• No Ontological Inertia: Enforces this when the time-travel magazine is destroyed by the alternate Tildy and Mr. Ostenfeld, erasing the altered timeline Hilda created.
• Outside-Context Problem: For Hilda and the multiple Mr. Ostenfelds anyway. Subverted in the case of Tildy, who knows what it is and what has to be done to stop it.

Deerfoxes

Other members of Twig's species, who reside in a mystical realm accessed through an Aurora Borealis.

---

• All Animals Are Dogs: They howl like wolves to call the light bridges down.
• Back for the Finale: The deerfoxes come back in the Grand Finale to help Twig rescue Hilda and Johanna from Fairy Country.
• Dimensional Traveler: They reside in a strange dimension and have the power to move between realms. This comes in handy in the season 3 finale, allowing them to invade the otherwise isolated Fairy Isle to rescue Hilda and Johanna.
• Fantastic Foxes: Half fox, and quite supernatural.
• Hard Light: What the bridges in their realm appear to be made of. They seem to have an ability to call them at will.
• The Marvelous Deer: Part deer and seemingly mystical in nature.
• Mix-and-Match Creatures: A combination between deer (possibly reindeer as both sexes appear to have antlers) and arctic foxes.
• Shrouded in Myth: According to Wood Man, they are only really known about in folktales, with some scientists unconvinced they exist.
• Wintry Auroral Sky: What their habitat and the entrance to it resembles.

Yule Lads

The red one is Kertasnikir.

Voiced by: Andy Serkis (Kertasnikir)

A group of 13 diminutive tricksters working under Gryla.

---

• All There in the Manual: Only four of the 13 lads are named in the episode they appear in. All their names are given however in the tie-in novel Hilda and the Time Worm.
• And Starring: The end credits for their episode start with "With Andy Serkis as Kertasnikir".
• Bad Santa: Based loosely on the figures from Icelandic folklore.
• Bilingual Bonus: "Kertasnikir" is Icelandic for "candle-stealer," appropriate as he eats candles. Most of the other lads are not named in the show (the only other names we learn are Pvorusleikir, Ketkrokur and Stekkjarsaur), but have similarly descriptive names in the folk tales.
• Black-and-White Insanity: They recognize any kind of misdemeanor to be enough to make someone naughty on their book, and is enough to punish them for it. Justified, since they themselves don't want to be eaten and are positively desperate for substitute victims.
• Face Framed in Shadow: A trait the Yule Lads seem to have in common is that there is a little black spot underneath their hats. They still have visible eyes, however.
• Law of Chromatic Superiority: Kertasnikir is the only Yule Lad that dresses in red, and is the leader of the group.
• Non-Indicative Name: Subverted. At first, only seven lads appear, making Hilda and her friends wonder why they call themselves the 13 Yule Lads. It turns out that except for Kertasnikir, they work in shifts with other six identical Yule Lads.
• Trapped in Villainy: They aren't happy with their work of kidnapping people, however, if they stop, Gryla will eat them instead, so they are forced to act as her lackeys.
• Unrelated in the Adaptation: Usually depicted as Grylla's sons, here they're just naughty children she kidnapped and forced to work for her.
• Was Once a Man: They used to be human children that offered to work for Gryla in return for her not eating them.
• Would Hurt a Child: They willingly kidnap naughty children to feed to Gryla.

Gryla

An ogress who eats naughty kids.

---

• Child Eater: According to the myths and legends, yes.
• The Faceless: It is said that few have ever seen her face. Even when the audience finally gets a good look at her, her face is shown to be mostly hidden underneath a mask, with only her left eye visible.
• Horrifying the Horror: Even trolls, who were presented as the most dangerous magical creatures around until she showed up, keep a low profile when she's on the move.
• Karma Houdini: Is dealt with as bloodlessly as any other monster, despite being a known Child Eater.
• The Krampus: An analog, based on the mother of the folkloric Yule Lads from Iceland, being a monstrous cautionary tale against naughty children for a festive winter holiday.
• Our Ogres Are Hungrier: She's a hulking humanoid monstrosity who emerges every winter to hunt for children to eat. Exactly how she fits in among the other magical creatures of the setting, like trolls and giants, is unexplained however.
• Unrelated in the Adaptation: The Yule Lads are children she kidnapped rather than her own sons. Additionally, her husband Leppaludi and pet, the Yule Cat, is also totally absent from the show.

Introduced in Season 3

Pooka

Voiced by: Philippa Rice

A rather odd little shapeshifting creature who lives next door to Aunt Astrid.

---

• Adaptation Dye-Job: Unlike his mythological counterpart, who is traditionally described as being pitch black in color, the Pooka is yellow.
• Adaptational Wimp: In British folklore, the limits to a Pooka's shapeshifting are that they have animal features in human form and can only have dark fur in animal form. Here, Pooka's shapeshifting leaves a lot to be desired, with no one being fooled by it.
• May I Borrow a Cup of Sugar?: Every day, he goes to Astrid's house and demands that she give him random items, much to Astrid's annoyance.
• Meaningful Name: Pookas are shapeshifting fairies from Celtic legend. They are usually depicted as rabbit/cat-like creatures, but the Pooka of Hilda seems to be based on a particular illustration of the creature from the 19th-century book British Goblins: Welsh Folk-lore, Fairy Mythology, Legends and Traditions.
• Misplaced Wildlife: A mythological example. Much like the Barghest in Season 1, the Pooka is a creature from Celtic and British folklore shown instead living in a fantastical version of Scandinavia. However, his introduction to the series does help to emphasize make the greater usage of Celtic mythology in Season 3 through the fairy-related story arc when compared to the previous two, more Nordic-based seasons.
• Morphic Resonance: He's incapable of changing his face and skin tone, so his attempts at disguises always fail.
• Sitcom Arch-Nemesis: To Aunt Astrid. As her neighbor, he's totally harmless, but his incessant requests for random junk from her are an endless source of problems and annoyances.
• Voluntary Shapeshifter: He is a shapeshifter who can twist and morph his body into various creatures, including a dog, a snake, a woff, and even humans like Hilda.

Ancient Giants

From left to right: Kald, Halldór, Sigmund, Einarr, Valfreyja, Gertl, Aldinn, Bliða, Heimskr, Jaðarrokk. Not pictured, Drib and Myrkr^note  the giant with the long neck, seen in the first scene where Hilda spots the giants

The giants of old, who lived on the Earth thousands of years ago but left after realizing the world was becoming too small for them. Hilda encounters them after the Faratok Tree sends her and Wood Man back in time. Jorgen and Illus from Season 1 are also counted among them, but they have their own entries.

---

• Adaptation Relationship Overhaul:
  • In the information page for all the giants in Hilda and the Midnight Giant, Halldor is described as being on friendly terms with humans and well-liked by them. In the series, he’s as indifferent to them as the rest of the giants are, and the humans treat him as much of a threat as they do the other giants. This likely explains why he is shown leaving Earth with the other giants in the show, as opposed to having stayed behind as described in the books.
  • Sigmund is described in Hilda and the Midnight Giant as being rivals with Aldinn and frequently contesting his leadership. But in the show, he is the first to agree with Aldinn on the decision to leave Earth (though this could be also interpreted as reflecting the gravity of the situation for the giants).
• Adaptational Backstory Change: In Hilda and the Midnight Giant, Halldor is stated in the two-page foldout detailing all the giants as having remained on Earth when the others left. Here, he is shown leaping into space with the rest of the giants.
• Adaptational Curves: Valfreyja's design in Hilda and the Midnight Giant gave her a conical body similar to that of Jorgen's girlfriend back in the first season,^note Hence why it was initially believed that Jorgen's girlfriend was in fact Valfreyja, until "Hilda's Book of Beasts and Spirits" revealed her to be a different giant named Illus but in "The Giantslayer", she instead possesses a much more feminine figure.
• Adaptation Deviation:
  • Einarr is given a small tree growing on his right shoulder — a detail missing in depictions of him in Hilda and the Midnight Giant and Hilda's Book of Beasts and Spirits.
  • Bliða is shown nursing a baby giant in her arms in multiple scenes, despite the books never indicating her to be a mother.
  • Aldinn possess a much larger beard than in previous depictions, making him more greatly resemble Har (whom he is mixed up with in Hilda's Book of Beasts and Spirits). Additionally, whereas he is described in the books as being the first giant to leave Earth, the series instead gives this title to Bliða.
• Adapted Out: There are a few giants detailed in Hilda and the Midnight Giant who go unseen in this episode, those being the dragon-headed Fjallmar, the nisse-like Bjorg ^note Though his absence can be justified, as his biography in the graphic novels states he was an outcast who was fearful of the other giants, so he wouldn't want to hang out with them; additionally, he's said to have stayed on Earth when the other giants left, so he wouldn't have participated in their exodus, the truly colossal Har, the Ice Man, the hill-like Knolem, and the slug-shaped Brekkus the Thunderworm. The Ice Man and the Knolem are especially noticeable since they did appear in the giants' Early-Bird Cameo back in Season 1's "Chapter 2: The Midnight Giant" .
• All There in the Manual: Their names are only ever revealed in the graphic novel Hilda and the Midnight Giant and the book Hilda's Book of Beasts and Spirits. Most of them are also given more characterization in said materials (Aldinn is confirmed to be the leader of the giants, Drib is stated to in fact be the older brother of Kald, Sigmund is Jorgen's cousin, etc.).
• Ascended Extra: Gertl, Sigmund and Jaðarrokk had a brief appearance back in season 1's "Chapter 2: The Midnight Giant". Here, they and the other giants get a whole episode dedicated to them. Kald and Drib in particular get the most screentime and dialogue of them all.
• Attack of the 50-Foot Whatever: Most of them stand as tall as mountains, but even the smallest of them is still big enough to unknowingly crush somebody's house under just one of their feet.
• Cyclops: Heimskr differs from all the other giants in that he has only a single eye.
• Early-Bird Cameo: Many of the giants seen appear in season 1's "Chapter 2: The Midnight Giant" in flashback sequences as Wood Man explains the history of the giants to Hilda or as blink-and-you'll-miss-it cameos in the pages of Wood Man's book on giants (which also includes a few brief glimpses of the giants who go unseen in "The Giantslayer").
• Gentle Giant: None of them hold any ill will towards humans and can be reasoned with if one is willing to try. All the destruction they cause is purely by accident or when they are defending themselves from attacking humans.
• Horned Humanoid: Sigmund has two horns on his head.
• An Ice Person: Kald and Drib are both snow giants. Heimskr also has snow on his head for some reason.
• In a Single Bound: As previously seen when Jorgen and his girlfriend left Earth (and described by Wood Man in that same episode), the giants leave the world by simply jumping off-planet through their sheer size and strength.
• Long Neck: Heimskr and Myrkr both possess extraordinarily long necks.
• Multiple Head Case: Jaðarrokk has seven heads of different sizes, all looking in different directions.
• Our Giants Are Bigger: They are a race of primordial titans who shaped the world in ages past, but are now being forced to leave their home as humans spread across the land. And while they are certainly bigger than the forest giants, there are some notable size differences even among the group. Most of them rival Jorgen in size, but Gertl stands to the waistlines of the others, while Drib, Bliða, and Einarr are even smaller, only reaching the knees.
• Rock Monster: Jaðarrokk's body is made completely of rock. Several of the other giants also possess stony features; Kald for instance has a nose made of rock, while Halldor and Heimskr have stony growths on their skin.
• Stealthy Colossus: Several times in the episode, Kald amazingly manages to escape Hilda's field of vision. When she first appears, Hilda only notices her when she accidentally crushes a house under her feet, and when Hilda pursues her through the forest, Hilda ends up losing sight of Kald until the giant suddenly reappears from behind a cliff face.
• Tiny-Headed Behemoth: Halldor and Einarr both have disproportionately small heads compared to their vast bodies.

Eugene

Voiced by: Raj Ghatak

A laughing merman showman who is desperate for a captive audience.

---

• "Could Have Avoided This!" Plot: He traps Hilda and her friends into a maze of rivers he was "banished" to so he won't be stuck alone anymore, but at the end Louise points out to him that all rivers eventually lead to the sea, so he was never really stuck to begin with.
• Dastardly Dapper Derby: While not evil per say, he's mischievous, has a wicked sense of humor, and sports a bowler hat with a barnacle on it.
• Fish People: He's an amphibious humanoid creature with scaly green skin, sharp teeth, and fins on the side of his head in place of ears.
• Evil Laugh: After luring Hilda and her friends into his trap, he starts giggling menacingly—almost to the point of being Laughing Mad.
• The Hyena: He giggles a lot, mostly whenever he is having his way.
• Jack of All Trades: Downplayed. He isn't a jack of all trades, but as a showman, he is capable of many different things, including stand-up comedy, magic tricks, and even musical performances. At one point he refers to himself as a "triple threat", meaning he's equally good at acting, singing and dancing.
• Master of Illusion: As part of his magic tricks, he can conjure auditory and visual illusions to the point he seems to be a full-on Reality Warper.
• Our Mermaids Are Different: He's described as a merman, but rather than the classic human-torso, fish-tail appearance, he's a piscine humanoid with a small lure and fins for ears.
• Overly Long Name: His real name is spelled in the tie-in novels as "Llanfairpwllgwyngyllgogerynchwyrndrob". In the series, his real name is unpronounceable since it is pronounced by his gills. Either way, it's not hard to see why he just goes by "Eugene" on the surface.
• No Poker Face: His tendency to break into a Slasher Smile and start cackling whenever Hilda and her friends are about to fall for one of his tricks let them figure out how to beat him, though he eventually catches on and uses an illusion to compensate.
• Shout-Out: His full name is a shortened form of the infamously long Welsh village name Llanfair­pwllgwyngyll­gogery­chwyrn­drobwll­llan­tysilio­gogo­goch.
• Stage Names: "Eugene" is just the "surface name" he uses when interacting with humans on the surface, as his actual merman name (Llanfairpwllgwyngyllgogerynchwyrndrob according to the tie-in novels) is unpronounceable to anyone who lacks gills.
• Villain Song: Fittingly, given his nature as a showman, he gets a Broadway-styled one in the form of "Bottom of the Sea". It also doubles as his "I Am" Song, as it explains his backstory and who he is.

Spider-Frog

An ancient swamp-dwelling spirit resembling a cross between a frog and a spider.

---

• Ancient Evil: While more of a predatory beast than evil, he does try to eat Hilda and Johanna when they stray into his territory and break the seal placed on him.
• Animalistic Abomination: He is an ancient supernatural entity with a frog-like head, a prehensile forked tongue, six spider-like legs, and a pair of small forearms with spinnerets in his wrists.
• Blue-and-Orange Morality: He is thankful to Hilda and Johanna for freeing him, but decides to eat them anyway. When he discovers that he doesn't like how they taste, he declares that this means they can be friends.
• Determinator: He is utterly hell-bent and persistent on eating Hilda and Johanna and chases the two throughout the forest until he succeeds in eating them. Fortunately for them, he doesn't like the taste of humans, so he vomits them out.
• Evil Sounds Deep: "Evil" might be putting it too harshly, but he's certainly one of the most dangerous and frightening threats encountered in the whole series and has one of the deepest voices to go with it.
• Foreshadowing: When he states he is the only one of what he is, he points out that Hilda and Johanna would know what that's like, hinting at the reveal that the two of them are human-fairy hybrids, the only ones in existence.
• It Can Think: When he first appears, he comes across as an animalistic monster, but is in fact able to speak and converse intelligibly.
• Mix-and-Match Critters: Part spider, part frog. It even describes itself as originating from an era of the world when beings could not be so easily categorized or labeled as one thing or another.
• No Name Given: The closest he comes to being named is Johanna wondering if she should call him a Spider-Frog or frog-spider, as he says he's from a time when things were not so clearly defined. Hilda tells her to forget it however as the creature clearly did not want to be labeled. The tie-in book does refer to the creature as Spider-Frog.
• Sealed Evil in a Can: He was imprisoned at the bottom of a lake by Hilda's grandparents when he tried to eat Johanna as a child, and Hilda accidentally breaks the seal by removing the charm-net binding him.
• Shaped Like Itself: When Johanna asks it what it is, it simply responds that it comes from a time creatures had no name to be addressed and would rather not be categorized by anything. It just is.
  Hilda: So what are you, if you don't mind me asking?
  Spider-Frog: I'm from a time when creatures didn't have to be so clearly one thing or another. I have no word for what I am. I just am.
• Single Specimen Species: It describes itself as the only one of its species.
• Super-Persistent Predator: It is completely and utterly determined to eat both Hilda and Johanna, relentlessly pursuing the latter after successfully capturing the former.
• To Serve Man: He tries to eat Hilda and Johanna when they accidentally break the seal placed on him, though he promptly vomits them back out since humans taste disgusting to him.
• Too Spicy for Yog-Sothoth: Hilda and Johanna are saved from almost certain death by the simple fact the monster finds out it hates the taste of humans.

Fairy Entity (Unmarked spoilers)

Voiced by: Shirley Henderson

A spirit-like being that rules over Fairy Country.

---

• Ambiguous Gender: The voice of the Fairy Entity can change from high-pitched to very deep, which does not give a clear indication on the Fairy Entity's gender. The Fairy Entity might not even conform to any gender due to being a supernatural being.
• Big Bad: Of the third season, despite only directly appearing in a few scenes.
• The Blank: The Fairy Entity just has a circular glowing light for a face.
• Calling the Old Man Out: Astrid calls it out on its stubbornness to stick by its own self-imposed traditions despite the fact that they barely benefit it.
• The Corruption: The Entity's current presence corrupts the Fairy Country, causing the giant fungi to rot or grow into twisted slimy forms, and it's noted that the afflicted area is slowly spreading.
• Deal with the Devil: The Fairy Entity is willing to make bargains with mortals and even other fairies, and takes them very seriously.
• The Dreaded: While Hilda never meets the Fairy Entity (the one time she tries seeking it out being thwarted by Astrid) it is feared by her grandparents and great-aunt and the portion of the island corrupted by their presence is avoided.
• Early-Bird Cameo: While it doesn't physically appear until the flashback, its voice can be heard very faintly ^note So faintly in fact that it's borderline impossible to even notice without the captions letting you know someone is speaking much earlier in the episode, right before it hits Frida through the portal with a magic blast.
• Eldritch Abomination: Overall its appearance is more of a cosmic being rather than that of an ordinary fairy: it's entire body is warped in a night sky-like cloak and it has a glowing circle for face. It's even implied to be not just the Fairy Isle's ruler, but the Fairy Isle's embodiment (more specifically the living soul and consciousness).
• The Fair Folk: The Fairy Entity is a fae being with a glowing blue light for a face and rotting branch-like arms.
• Final Boss: It is the last major threat of the series, even though it doesn't put much of a fight or personally confront heroes.
• Fisher King: Its presence corrupts the Fairy Country due to its current status, causing the fungi and plants to rot. It can also cause corrupted fungi to sprout at-will and can manipulate the terrain to some extent.
• Genius Loci: It's implied that it is the personification the Fairy Isle itself.
• Good Old Ways: It's never wanted Johanna from the start and only keeps the claim on her life because it is the Entity's way of living to make bargains. Astrid outright calls it out for this, stating that it's literally stuck in its own ways and thus it is dying.
• Green Thumb: It can cause fungi to sprout at-will.
• Greater-Scope Villain: In trying to claim Johanna when she was a child, leaving her traumatized, the Fairy Entity is (mostly) responsible for the events of the series.
• Life Drinker: Implied to be the case, as Astrid notes that the Fairy Entity is dying and will consume her life force to sustain itself.
• Voice of the Legion: The Fairy Entity normally speaks in a high-pitched multi-tonal voice, though its voice grows deep and distorted when it becomes angry.
