Original Ghouls

Original Ghouls General Tropes

    open/close all folders 

     Frankie Stein
Voiced By: Kate Higgins, Cassandra Lee (Welcome to Monster High-current)
A girl created by Frankenstein's Monster and his bride (mad scientists in this universe), and their daughter. In most Generation 1 continuities, she was stated to only be 15 days old at the start and attended high school as the "new girl".

Starting with Welcome to Monster High, she's 115 days old and works with Draculaura, Clawdeen and their respective families to build the school. Plucky, fun-loving and klutzy, she alternates between series Protagonist and Deuteragonist.
  • Accidental Athlete: In "Fearleading Tryouts" she trips into the gym and with a bit of convenient pratfalls and a few of her own flying limbs, aces the audition.
  • Adaptational Intelligence: In the original series, Frankie is portrayed as either an average or slightly above average student. Post Welcome to Monster High, she is the resident scientific and technological Teen Genius.
  • Adorkable: She's the daughter of a scientist, and has her father's roots, but she's also a teenager who is literally very new to the world. Also, post-reboot, she's got the highest GPA at the school.
  • Amazing Technicolor Population: She has mint green skin.
  • Badass: Freaky Fusion confirms: try to absorb her friends and she will take you out. Also, as her 2016 SDCC doll proves, she can hold her own as a (non-lethal) Ghostbuster.
  • Badass Adorable: With big eyes, naivete and a nearly ineffable good attitude, this Frankenstein girl seems strangely cute!
  • Creepy Doll: Her pet in the reboot is a haphazardly sewn-together teddy bear with bolts.
  • Cute and Psycho: Her Home Ick final definitely shows her scary mad-scientist side, as does the Electrified trailer.
  • Cute Clumsy Girl: Due to her tendency to fall apart in the least convenient moments.
  • Disney Death: In Freaky Fusion, she uses her own life force, or Spark, to take down a rampaging creation of her grandfather Viktor that's captured her friends and threatens to destroy them. Doing so however uses her up, and she's effectively dead until her friends and schoolmates pull together to recharge her.
  • Exotic Eye Designs: Her Sweet Screams look gives her bolt-shaped pupils.
  • Facial Markings: Her Ghouls Rule doll has blue lightning under her left eye, and her dance the Fright Away release gives her a yellow Aladdin Sane-esque lightning bolt over her left eye.
  • Frankenstein's Monster: Her father's the trope namer, and she the descendant and an example.
  • Good Scars, Evil Scars: Emblematic stitches all over her body, which are all neat and clean.
  • Helping Hands: Frankie’s hands whenever her stitches come loose.
  • The Hero: She always changes the way things were for the better.
  • Idea Bulb: Variation. Her neckbolts often spark when she gets an idea.
  • Identical Stranger: To a human scientist who came to Skull Shores sometime in the 20th century, sharing the same striped hair and heterochromia. Some fans believe that due to Frankie's patchwork nature, that same scientist may have been Human Resources for Frankie's head.
  • Mad Scientist: Well, she did build herself a boyfriend once.
  • Multicolored Hair: Although usually only possessing black and white hair, she gets blue and yellow hair in some releases, and the Roller Maze green for that doll.
  • Naďve Newcomer: At first, but integrates well. She makes it her own mission to help other newcomers.
  • Scary Stitches: Naturally. Even her Generation 1 and 2 pets have them: first Watzit, then a nameless stitched-up teddy.
  • Sense Freak: With all the basic intelligence of the average 15-year old, yet little experience outside, everything is new to her, and she wants to experience it all. She learns more over time
  • Ship Tease: With both Jackson and Holt — twice! They sort of got together, took a break so the boys could sort out their issues, and had been teasing at getting back together for a while.
  • Shock and Awe: Powered by electricity, and can use it in many ways—for example, in direct combat with jumper cable clamps on her bolts while standing on a metal floor.
  • Shout-Out: Her Gaga look is based on the rococo-esque hairstyle Gaga sported at the Brit Awards in 2010.
  • Skunk Stripe: Alternating skunk stripes throughout her hair.
  • Stage Magician: Her role in the Freak Du Chic, where her independent body parts come in handy for the separation cabinet.
  • Symbol Motif Clothing: Bolts, both of metal and lightning.
  • Tomboyish Name: Helps the pun.
  • The Ugly Guy's Hot Daughter: Well, her father is Frankenstein's Monster.
  • Yellow Lightning, Blue Lightning: Both colors of lightning feature frequently in her outfits, sometimes both in the same ensemble.
  • Younger Than They Look: At the beginning of the series proper, she's 15 days old. Then, her age was listed as "How many days has it been now?". In the current continuity she's 115 days old.

Voiced By: Debi Derryberry
The adopted daughter of Dracula. At 1600 years old she's peppy, sweet, and loves helping and being around her friends (and her boyfriend Clawd Wolf). Notable as being one of the only, if not the first, true vegetarian vampire, as she faints at the sight of blood and survives mostly on supplements and fruit, and shortly ran her own newsletter on the topic: V.A.M.P. - Vampires Advocating Meatless Protein. Diaries and other material heavily imply she wasn't always like this. After long being devoid of the powers granted to vampires, she received them in Frights, Camera, Action!.

Post-reboot, she's lived a long time with only her father; and along with Frankie, Clawdeen, Clawdeen's family, and Dracula she builds Monster High. She also has her vampire powers from the start. She's still sweet, slightly ditzy, and vegetarian.

  • A Day in the Limelight: She's the main star in "Frights, Camera, Action", and the plot centers around us learning some of Draculaura's history.
  • Afraid of Blood: Draculaura has a tendency to faint even at the mere mention of blood.
  • Amazing Technicolor Population: Her skin is light pink, with a hot pink heart birthmark on her right cheek.
  • A Riddle Wrapped in a Mystery Inside an Enigma: Her collector's edition doll's box describes her as "A riddle wrapped in sweetness inside an infectious laugh".
  • The Atoner: Her diary actually implies that she is one. When her dad tells her that he wishes she'd return to "proper" vampire ways, she writes that she is resolved to never go back to how she was before.
  • Cannot Keep a Secret: Frequently. This is exploited mentally by the ghouls to set up Scarah and Invisibilly, since both are scared that Scarah's telepathic powers will make fools out of them. Clawd tells Billy that Scarah has a date in the cemetery, and Cleo tells Draculaura that Billy has a date in the cemetery, knowing that once she sees Scarah, the latter will pick up on her thoughts about the supposed date. It works, leaving Draculaura totally confused when Scarah and Billy are seen walking together the following day.
  • Cherry Blossom Girl: Her Monster Exchange ensemble has shades of this, with her typical pink in her hair, and her outfit inspired by various elements of traditional Japanese dress including a cherry-blossom branch with bats instead of flowers and blossom patterns on her outfit.
  • Cool Pet: Count Fabulous the bat in Generation 1, Webby the not-so-Giant Spider in Generation 2.
  • Cute Little Fangs: She never uses them to suck blood, though.
  • Dark Horse Victory: In "Talon Show", a webisode mainly focusing on Cleo and Clawdeen going to huge measures to score a role in a play, she gets the part at the end. And does pretty well.
  • Deuteragonist: Ostensibly, through marketing domination, multiple specials dedicated hugely to her, her own collector's edition doll and promotion to face of the franchise in 2016. She and Frankie even shared a Surprise Party in Volume 1 webisode "Party Planners".
  • The Ditz: To a very large degree, but she can occasionally show insight.
  • Elegant Gothic Lolita: Many of her outfits show degrees of this, with spooky touches like a bat-shaped ruffled collar or a spiderweb-patterned mermaid dress.
  • Exotic Eye Designs: Her Sweet Screams design includes heart-shaped pupils.
  • Facial Markings: Her Dance the Fright Away release gives her a Lizzie Hearts-esque pink heart around her right eye.
  • Friendly Neighborhood Vampire: Draculaura certainly comes across as one.
  • Fun with Acronyms: her newsletter "V.A.M.P." — "Vampires Advocating Meatless Protein."
  • Genki Girl: In the beginning she was super flighty and hyper, but she's a little mellower now.
  • Girlish Pigtails: Featured in many of her dolls, and it's her default hairstyle in the cartoon.
  • Girly Girl: To Lagoona's Tomboy, in the original ghouls.
  • Girly Girl with a Tomboy Streak: During the Victorian era, at least. Her outfit may be a lacy dress with a parasol, but she's also wearing a bow tie and a top hat, traditionally masculine accessories which would never be seen on a lady during that time.
  • Granola Girl: Vegetarianism is a big part of her character, but with a passion for legendary shopping sprees and luxury items she's far from a dirty hippie.
  • Happily Adopted: As revealed in her second edition diary, by Dracula. And later on also by his wife, Ramoanah.
  • Heroic Bastard: Camilla and Gaius never wed, making her this.
  • Hidden Depths: Draculaura's 2nd edition diary began to go into her Dark and Troubled Past—her father, rather than the Dracula we know, is an even older master vampire (Bram Stoker's villain was a less powerful upstart who used her father's name to impress and terrorize locals til he fell prey to Laser-Guided Karma), who took in Draculaura (perhaps just Laura then) and her mother "when no one else would" over a thousand years ago. The brief diary for her collector doll provided a timeline— her father was the Roman soldier Gaius who fell in love with her mother Camilla, but he died in battle before she was born. Dracula, having known and been friends with Gaius' great grandfather moved his home to Dacia and took Camilla in. Draculaura was named in his honor at birth. In the year she turned 16, a plague swept the village they lived in and claimed Camilla's life. Fearful to lose Draculaura as well, Dracula turned her into a vampire. The collector's edition diary even describes her as a riddle.
  • I Love You, Vampire Son: A platonic example. Dracula cares a lot about her, and lets her have whatever makes her happy—even if he doesn't completely approve some of her less orthodox life choices.
  • Joshikousei: In "Sayonara Draculaura", she gets a Sailor Fuku at the Shibooya exchange school—matching all the students there, natch. Sailor-type outfits also include her Skull Shores swimsuit and Shriek Wrecked dress.
  • Kid-Appeal Character: Cute, cheerful, and iconically designed.
  • Let Me Get This Straight: In Boo York, Boo York after Pharaoh's big performance, she rattles off one of these as a run-on paragraph. True to form for MH's resident Motor Mouth.
    Draculaura: So let me see if I've got this right. First Deuce breaks up with Cleo. Then Cleo decides to do that comet ceremony thing with Seth Ptolemy. But Seth is all like, "Nope, never mind, and by the way, I'm that rapper Pharaoh and (makes gang signs) I want to fang out with Catty Noir." And now you're saying that this party is completely out of King Tutankrab-rolls? (crying noise)
  • Make Me Wanna Shout: In her bat form, she can scream loud enough to take someone out.
  • Meaningful Name: Laura is from the Roman laurel, meaning peace. Draculaura is a uniquely peaceful vampire—fully vegetarian and kind to a fault, despite her sad past and fearsome forebears.
  • Military Brat: Her birth father and adoptive father both were in the Roman army. The former died in battle.
  • Missing Mom: Camilla, who died of The Black Death. Draculaura now has a not-wicked stepmother (Ramoanah) as of "Draculaura and the New Stepmomster".
  • Motor Mouth: While they're driving to school, she puts Clawd to sleep with a gossip tirade.
  • Multicolored Hair: While usually black with pink streaks, it has been pink with black undertone, or black with yellow and pink streaks.
  • Obfuscating Stupidity: In Frights, Camera, Action she uses this to distract Stoker from the ghouls, amping up her ditziness.
    Draculaura: Pink's my favorite color. What's yours?
    Stoker: (exasperated sigh)
  • Odango: Her doll for the Fearleading 3-Pack sports odango pigtails.
  • Official Couple: With Clawd, in Generation 1.
  • Older Than They Look: She's 1599 years old at the beginning of the series proper. A big show was made of her turning 1600 as it was used for both a doll collection/line (Draculaura's Sweet 1600) and it was the main event of Why Do Ghouls Fall In Love.
  • Only One Name: One of the few characters who has no last name that we know of.
  • Our Vampires Are Different: Not too different though, just vegetarian.
  • Parasol of Prettiness: Justified in this case, as the sun protection her parasols provide is necessary for her.
  • Perky Goth: Just about the happiest gothic lolita vampire you've ever seen!
  • Pink Heroine
  • Pink Means Feminine: She is one of the more girly characters among the main cast, with pink streaks in her hair, predominately pink outfits, and pale pink skin.
  • Pointy Ears: Her entire facial design is a bit of a shout-out to Bela Lugosi.
  • The Hero: 2016 onwards.
  • The Pollyanna: She's got an idealistic view of life that she never lets go of. Considering the Dark and Troubled Past we've gotten glimpses of, that could be her way of dealing with life—letting go of old miseries and looking towards the bright and happy things and the monsters she loves.
  • Proper Tights with a Skirt: Her G1 basic outfit looks like fishnets under a miniskirt. They're actually fishnet tights which end right above the boots. Subverted with her G2 basic outfit, a dress, only having tights in its CGI adaptation.
  • The Protagonist: She's the leading character in the short anime adaptation, and the protagonist of the series in and after Welcome To Monster High.
  • Purple Eyes: They're a very light mauve, not grey.
  • Rapunzel Hair: Her Party Hair doll has her hair tied in a ponytail, but even then, it reaches her ankles.
  • Rose-Haired Sweetie: Mostly pink hair, and a really sweet kid.
  • Shout-Out:
  • Shown Their Work: In her Monster Exchange doll, her kimono-style dress is folded right over left at the top—a look reserved for the dead.
  • Smitten Teenage Girl: Often in Generation 1, a main plot point including her was her various follies with dating—until she became an Official Couple with Clawd.
  • Stocking Filler: In her "Day at the Maul" fashion pack, the skirt comes with black stockings over white fishnets.
  • Symbol Motif Clothing: Hearts, bows, and bats. Lips will occasionally show up in her outfits, too, due to the association with a vampire's bite.
  • True Blue Femininity: The reboot makes light blue the accent color to her standard color scheme.
  • Vampire Vords: She can pronounce her Ws, at least, but she otherwise has a noticeable (and very cute) Hungarian/Romanian accent.
  • Vampires Are Rich: Legendarily loaded—coupled with Cleo, it's seen in Scaris: City of Frights that their combined shopping power stacks a wheeled cart to the roof.
  • Vegetarian Vampire: Played absolutely straight. She drinks no blood at all.
  • Visual Pun: Her Great Scarrier Reef transformation gives her a lower body of webbed tentacles, a feature of the vampire squid.
  • Weak, but Skilled: Small in normal and bat form, but thanks to evasive maneuvers and selective supersonic screaming she's a worthy opponent against (for example) murderous acrobatic zombies with serious claws.
  • Why Did It Have to Be Snakes?: In the beginning, she couldn't even say the word blood without fainting (or nearly fainting). As of about Volume 4, this doesn't come up anymore.
  • Winged Humanoid: Her Ghoul To Bat doll gives her a large pair of hot pink satin wings, patterned with fanged hearts and bats. The play factor comes from transforming the doll through pulling the top of its dress out and downward, exposing the wings.

     Clawdeen Wolf
Voiced By: Salli Saffioti
Daughter of The Wolf Man. A fashionista and neophyte fashion designer, she's forthright and has a knack for looking into tough situations. Fiercely loyal to her friends, fiercely protective of her friends, and all-around fierce.
  • American Accents: She and her sisters, but not her brother speak with a faint accent. Ms. Saffioti has a New York heritage, and puts this forth while acting to give Clawdeen a bit of urban vibe, so when the other sisters came in their voice actresses followed suit.
  • Ascended Extra: As with Twyla, zig-zagged by her Freak du Chic doll: more detailed and different than her minor appearance in said webisodes, but only available at Target.
  • Bald Women: In Clawd's first release diary it's revealed she once accidentally snipped all of her hair off. It grew back quickly, but it still left her pretty down. Draculaura even suggested her and Frankie cut all their hair off too in solidarity... until Frankie reminded her that unlike werewolves, their hair would take a much longer time to grow back.
  • The Big Girl
  • Big Sister Instinct: Djinni learns this in 13 Wishes: don't mess with Howleen. And in Welcome To Monster High, it's implied she would've mauled Frankie and Draculaura if they hadn't proved themselves to be monsters, and friendly.
  • Broken Pedestal: Moanatella Ghostier was her fashion inspiration until she learned exactly how she'd been keeping her place in the industry.
  • Cute Little Fangs: Yeah. Not so much in wolf form, where they go full-on More Teeth than the Osmond Family.
  • Facial Markings: Green crescents over and under her left eye in her "Dance the Fright Away" release.
  • Fascinating Eyebrow: Her reboot dolls all have a slight version of this.
  • Fashion Designer: She sketches and creates many of her and her friends' outfits, and her first big stint as one is the main point of Scaris: City of Frights.
  • Femme Fatalons: Which she once used to puncture a casketball just by gripping it too hard.
  • Our Werewolves Are Different: While Clawdeen's features are consistently wolflike, she usually keeps her animalistic side under control... except during the full moon (when she becomes more daring and energetic than usual). "Fur Will Fly" showed her using this transformation to beat Heath Burns (he didn't know that day was a full moon, and it gave her super-speed, beating him even with his head start).
    • Welcome To Monster High gives her a real wolf form, and shows she can switch between wolflike girl and actual wolf.
  • The Fashionista: Notable in that she views fashion both as an art and in a business sense; she hopes to one day own her own fashion line, and plans her classes accordingly. She aspires to become a Fashion Designer.
  • Gold Makes Everything Shiny: Few dolls of hers have been released without a gold accent. This is fitting, since there's no way she'd be wearing silver.
  • Hairy Girl: The reboot gives Clawdeen some molded fur on her shins and forearms.
  • Massive Numbered Siblings: Pre-reboot it was obvious Clawd, Howleen and Clawdia weren't Clawdeen's only siblings. It was never made clear exactly how many she has, but her family's quite large. Post-reboot Clawd, Howleen and Clawdia are nowhere to be seen... but we do see a very large amount of Palette Swap younger brothers.
  • Multicolored Hair: See Kaleidoscope Hair.
  • My Brother Is Off Limits: This with Draculaura and Clawd in the early stages of their relationship, but she's now come to accept it—and nobody's threatening it on her watch.
  • Nobody Touches the Hair: She is adamant about being her own hair stylist, and does a very good job.
  • Kaleidoscope Hair: It's explained in-universe that the one benefit of Clawdeen's constantly growing hair is that it allows her to be very experimental with it, so in each doll of hers her hair undergoes a substantial color change.
  • The Nose Knows: It comes with being a werewolf. The [Trope Name] is even a family catchphrase.
  • The Rival: At first with Cleo, but they got over it.
  • Traumatic Haircut: See Bald Women.
  • Rapunzel Hair: Her hair is constantly growing—and not just the hair on her head, leading her to have to pluck and wax continuously (she has to do so three times a day, as noted by her "Dawn of the Dance" itinerary). However, it also allows her to be more experimental with her hairstyles— shown in the doll lines with various lengths.
  • Shout-Out: Her hairstyle on her Gaga doll is the soda-can rollers seen in Telephone.
  • Supernatural Gold Eyes
  • Symbol Motif Clothing: Crescent moons, bones, and/or animal print patterns feature in almost every outfit she wears.
  • Unusual Ears: Wolf ears, on top of her head.
  • You Gotta Have Blue Hair: She's no stranger to uncommon shades in her locks. She usually has purple (and acid green) accents, but she occasionally has teal and the hair on her Fierce Rockers doll is a proper blue.
  • Zipperiffic: This is occasionally a theme in her outfits.

     Lagoona Blue
Voiced By: Laura Bailey, Larissa Gallagher (Great Scarrier Reef-present)
Daughter of the Sea Monster. A level-headed and laid-back character, Lagoona spends most of her time in the water (either in the ocean or the school's swimming pool) and is the gang's resident surfer girl and school swim captain. Amiable and helpful to almost everyone, she usually has to ground her friends if they get carried away. As a saltwater monster she frequently has issues with her freshwater boyfriend Gillington "Gil" Webber, because of his parents' prejudice towards her.
  • Australian Accent: Lagoona's an exchange student from "down under". Specifically, the Great Scarrier Reef, down under...water.
  • Cool Big Sis: To three younger brothers and a sister.
  • Cloudcuckoolander: Portrayed as a spacey girl who (literally) bathes in moisturizer in the anime adaption.
  • Day in the Limelight: The spring 2016 CG special Great Scarrier Reef has her as the main character.
  • Facial Markings: Aquamarine stars on her right eye in her "Dance the Fright Away" release.
  • Fish People
  • Former Friend of Alpha Bitch: Used to be friends with Kala, and until they talk things out at the end of the Great Scarrier Reef, she's Lagoona's worst nightmare.
  • Green Eyes: Drawn especially to look piscine.
  • Light Haired Swimmer
  • Missing Mom: Her mom's fine, but Lagoona can't see her much while in America since she's an ocean nymph from the Great Scarrier Reef.
  • Multicolored Hair: Lagoona has aqua blue streaks in her otherwise blonde hair due to the chlorine in the school's swimming pool, and in all doll releases this trend continues. Her Great Scarrier Reef release adds a hot pink streak.
  • My Greatest Failure: As a kid, she was passionate about dancing and won several awards. Then, thanks to Kala tying up her shoelaces in a fit of jealousy, she froze up at a crucial moment of a performance in front of almost every resident of the Great Scarrier Reef. This incident spurred her on to leaving the Reef for Monster High, gave her intense stage fright, and made her refuse to dance in public for years.
  • My Greatest Second Chance: Posea's the cause of this, dragging her back to the Reef with her magic to overcome her fear... which is so bad it's wilting her "sea lifeline", or the flower representing her lifeforce.
  • New-Age Retro Hippie: The aesthetic of her "Beach Beasties" doll, which bears great resemblance to Viperine Gorgon, who was released later.
  • Official Couple: With Gil, and the second oldest one next to Cleo and Deuce.
  • Only Sane Woman: Lagoona is the most down-to-earth, level-headed member of the main group. Also in the videogame New Ghoul in School she's the only one in the Council besides the Player Character who stays un-cursed, and the de facto leader of the un-cursed students.
  • Performance Anxiety: She was humiliated as a child, and now freezes up every time she goes onstage. Thank Kala for it.
  • Shout-Out: Her Zomby Gaga doll has hair and a headband evocative of Gaga's looks in Judas and Telephone.
  • Stocking Filler: In her basic outfit, she wears fishnet stockings.
  • Super Speed: Post-reboot, she has this even on land and on her skateboard.
  • The Tomboy: To Draculaura's Girly Girl.
  • Unusual Ears: Lagoona actually has fins for ears.
  • You Gotta Have Blue Hair: Blue streaks in every release.
  • Youthful Freckles

     Cleo De Nile
Voiced By: Salli Saffioti
Daughter of the Mummy, here Ramses De Nile by name. Resident Alpha Bitch and head of the fearleading squad, she's known mostly for her wealth and icy personality at school. In truth, she's quite sensitive and down to earth, but has been groomed to think of herself as better than everyone else.

Post-reboot she's a Lovable Alpha Bitch from the start, found by the ghouls in her tomb.
  • Arranged Marriage: In Boo York, Boo York Ramses and Nefera attempt to manipulate her into one with Seth Ptolemy, named a promise ceremony.
  • Bandage Babe: Wraps on her arms pre-reboot, and molded wrappings on her body, left arm, and right leg post-reboot.
  • Big Bad: Of the first TV Special and the first half of the Volume 1-webisodes.
  • Characterization Marches On: Has what might be the strongest and most consistent development of any character in the series.
  • The Cheerleader: Head fearleader of the squad.
  • Cool Crown: She'll occasionally wear Egyptian tiaras, such as in her Boo York and Music Class dolls.
  • Coordinated Clothes: Done subtly with her Boo York, Boo York two-pack release, where she reflects Deuce's outfit with the snakes on her shoes.
  • Defrosting Ice Queen: From a narcissistic, self serving Alpha Bitch antagonist to a generous, loyal true leader.
  • Department of Redundancy Department: When introducing herself to Elle, she says she's "of the De Niles". So, essentially, she's saying she's "of the 'Of the Nile' family".
  • Establishing Character Moment: Her G2 "Meet The Ghouls" video has her hosting a talk show, with herself as the guest. Naturally, there's a bit of ego-fanning back-and-forth between host Cleo and guest Cleo, but she does take a moment to give a genuinely heartwarming shout-out to her friends, which perfectly illustrates her character.
  • Facial Markings: Besides her regular crystal-shaped left birthmark under her left eye, she gets five more diamond-shaped ones under her right in her "Dance the Fright Away" release.
  • Family Honor: Most of the more ambitious things Cleo does is because she feels obliged to as a De Nile.
  • "Freaky Friday" Flip: "Freaky Fridate" has this happen with Ghoulia when she accidentally touches one of Daddy's idols that Ghoulia's also holding.
  • Gold Makes Everything Shiny: Not a doll release of hers without a gold accent, and her favorite color (shared with Clawdeen) is gold. Her reboot wrappings are also slightly gold, to tell from her skin.
  • Grapes of Luxury: Her favorite food is grapes, and this is how she prefers to eat them.
  • Hair of Gold, Heart of Gold: To go with her Jerk with a Heart of Gold, Cleo takes this to the highest level by having actual streaks of gold in her basic look's otherwise brown hair. All of her doll releases flaunt a splash of gold hair.
  • Harp of Femininity: Her Music Class release gives her a copper-toned one that resembles a row of teeth. The upper row can be removed to reveal an oversized comb for the owner to use.
  • Heel–Face Turn: Cleo started out as a bit of a snob/bully and the series' Big Bad, but has progressed into a supportive friend, especially in the Breather Episode about Ghoulia and Dead Fast. She is now a part of the Original Ghouls, and has gone from Alpha Bitch to Lovable Alpha Bitch for good.
  • Hidden Depths: At first a Straw Character antagonist, her vulnerabilities and insecurities have now come to light. She's proud and domineering, but she's truly a princess of the people. In Boo York, Boo York, it's shown in her heart she knows that as a queen-to-be, she must give the people what they want.
    • As of Season 3, she treats all of her friends as she does Ghoulia - caring and compassionate but still dominant.
    • The diary included in her 'Gloom and Bloom' release is a richly detailed account of her backstory and how her family came to be in their current form.
  • Hidden Heart of Gold: Her growth in becoming a nicer person comes to a head when she sends all ten-thousand of her royal servants to the comic auction that Ghoulia couldn't attend in order to win said comic for her. But, of course, the comic is slipped to Ghoulia discreetly, and Cleo tells the other ghouls not to let this info get around and ruin her rep.
  • Icy Blue Eyes / Innocent Blue Eyes: Her sky-blue eyes accentuate her ice queen personality, but also play up her kindness of heart and anxiety about her role. The latter is shown extensively in Boo York, Boo York.
  • Jerk with a Heart of Gold: Cleo can be quite stuck-up and mean to the ghouls, but is also happy to help them when there is a problem. She "secretly" thanks Ghoulia for all her help by getting her the rare Dead Fast comic.
  • The Lancer: She has connections.
  • Lovable Alpha Bitch: Cleo acts egocentric and temperamental, but when push comes to shove, she's a kind and loyal friend.
  • Meaningful Name: "De Nile" sounds like "denial", fitting for her original Never My Fault attitude and superiority.
  • Missing Mom: Crosses with Chekhov M.I.A.: Robecca finds her in her SDCC diary! For this, Cleo's indebted to Robecca.
  • Multicolored Hair: Normally dark brown and gold, but she's had teal and blue colors. Her Boo York doll has copper accents instead of gold.
  • Mummy
  • Official Couple: With Deuce. Also Clawd, pre-series.
  • Oh Crap!: She's given some of the series' more notable examples.
    • In "A Scare of a Dare" Frankie texts some boys "Party at my house, spread the word." Cleo laughs, disbelieving, and says that Frankie's parents will freak out when all those people show up at their house. "My house?" says a puzzled Frankie. "Cleo, it was your phone." Cleo grabs the phone, realizes Frankie was right—and Cleo's eyes go wide with dread as she goes, "Oh no."
    • "Freakout Friday" showed a bigger one when Ghoulia, who Cleo gave the Amulet of Nuckennutten to, is gone. Since the amulet protected the wearer and those with her, Cleo thought Ghoulia would stay close to her, thus keeping Cleo safe. Realizing she's gone, Cleo realizes she's just as much a target as the others.
  • Oh My Gods!: Due to being of Egyptian heritage, she often replaces "God" with "Ra".
  • Older Than They Look: She's 5843 years old, "give or take a couple". Post-reboot, she's 3357 years old.
  • Rich Bitch
  • Royal Brat: Egyptian heritage, folks!
    • This behavior was drilled into her by her father whom she was entombed with for several thousand years. She's gotten much better, though.
  • Seductive Mummy
  • Shout-Out: Her Gaga doll is based on the Poker Face era, with the long hair and bangs seen in Gaga's earlier videos.
  • True Blue Femininity: She exudes it more than the others.
  • "Well Done, Daughter" Ghoul: In Ghouls Rule! and Boo York, Boo York.
  • Whip It Good: Post-reboot, she can use her wraps in this way—but in a more full body wrap style, instead of actually whipping others.
  • You Gotta Have Blue Hair: Various releases give her teal or blue streaks, and in her Creepateria release it's got purple streaks.

     Ghoulia Yelps
Voiced By: Audu Paden
Daughter of the Zombies. Despite only being able to speak zombie, she's widely known as the smartest girl in school. She is also Cleo's best friend (and all-around personal assistant).
  • '80s Hair
  • Adorkable: Totally. The Geek Shriek line plays this up.
  • Amazing Technicolor Population: She's a very light grey.
  • Awesomeness by Analysis: In "Dodgeskull" she calculates in "Charlie-Vision" how best to take out a group of heckling classmates with a dodgeball. She gets them all and nails the lead heckler a few times for good measure—despite the fact she should have lost the game the moment she dropped the ball.
  • Badass: As revealed in Unlife to Live. She single-handedly solves ALL the problems in the school, but nobody knows...and she just appears to be sitting around.
    • And in Boo York, Boo York (along with Abbey Bominable) is able to stop Astranova's ship from crashing into Boo York City, averting an Earth-Shattering Kaboom.
  • Badass Adorable: Big eyed adorkable zombie girl who is shown in Freaky Fusion to be able to fight a dinosaur back into its' own time.
  • Badass Bookworm: Solves big problems through intelligence, and converted a significant part of the school underbelly into her own personal lab.
  • Beehive Hairdo: Her Love's Not Dead doll has this.
  • Creator Cameo: See Crossdressing Voice.
  • Crossdressing Voice: Ghoulia's actually voiced by the producer/director of the series, Audu Paden.
  • Curtains Match the Window: Light blue.
  • The Dragon: To Cleo. She is the mostly in the first movie and the first season of the webisodes, but with Cleo having a Heel–Face Turn, Ghoulia gradually grows into her own character.
  • Exotic Eye Designs: Her Sweet Screams doll has gummy-worm-textured irises, and her Love's Not Dead doll gives her eyes red reflections.
  • Fantastic Racism: In her diary, she implies that that zombies are not well liked for being hard to understand and their sluggish behavior. Ghoulia even buys a "Zombies Are Monsters Too" shirt to make a statement, but can't bear to wear it openly.
  • "Freaky Friday" Flip: "Freaky Fridate" has this happen with Cleo when Cleo accidentally touches one of Dad's idols that Ghoulia's holding.
  • Frozen Face: Though she can occasionally force a rather pained-looking Un-Smile, a groan, or even, in the case of the webisode "Mad Science Fair", a truly epic Slasher Smile that only manages to dodge being terrifying by happening as she finally gets back at Cleo for using her.
  • Gadgeteer Genius: Not only is she the smartest ghoul in the school, but she once invented a two story tall trash-to-fuel recycling machine as a Mad Science Fair project. Also note the comet-stopping.
  • Gamer Chick: Not as pronounced as it is with Kjersti Trollson, but Ghoulia's fond of gaming and regularly gets high scores in a Dead Fast licensed game. She beats Kjersti twice: in an online MMORPG PvP battle, and in the leaderboard for Dead Fast. When Kjersti comes to Monster High to meet her greatest rival, they end up becoming friends over their mutual love of video games.
  • Good with Numbers:
  • Hollywood Hacking: Ghoulia can hack anything in a few seconds with her laptop, including satellites. Well, almost anything...she couldn't hack the gossip column to find out who was running it.
  • Hollywood Nerd: But also quite popular.
  • Intelligible Unintelligible: The zombie language is nothing more than groans, but the other monsters mostly understand her.
  • Meganekko: Rarely seen without her pair of signature cat-eyes, which she herself refers to as "nerd glasses".
  • Morality Pet: To Cleo as her best friend: in Fright On! her unconditional friendship makes Cleo tear up.
  • Multicolored Hair: Normally a blend of powder blue with darker highlights, but Roller Maze has the trademark green streaks, Sweet Screams is darker blue and black, and Love's Not Dead has just the darker blue.
  • Nerds Are Sexy: Even for a zombie nerd girl, she's quite a hottie.
  • Official Couple: With Slo Mo.
  • One of Us: In-universe; the 2011 Monster High San Diego Comic Convention doll is Ghoulia dressed in a custom version of the costume worn by her favorite superhero, Dead Fast, that she just happens to be wearing to Necro Con. She's also in the school's comic book club.
  • Our Zombies Are Different: Ghoulia can't speak anything other than zombie, but she happens to be the smartest student in school and prefers fast food over brains. Sometimes she might only do one major action but it makes or saves the day in each episode... and movie.
  • Phrase Catcher: "Ghoulia's right!" Pretty much every one of the main characters has said this at least once.
  • Retraux: Her theme is decidedly retro, with cat-eye glasses and bold, simple patterns in her outfits.
  • Shrinking Violet: The shyest among the ghouls.
  • The Smart Girl: She's very intelligent, and the others turn to her when something technical needs attention.
  • Symbol Motif Clothing: Cherries are strongly associated with her.
  • Techno Wizard: She's great with that laptop of hers, and made a video game just to decide who she'd date in less than a day.
  • Voice for the Voiceless: In the anime adaption, Ghoulia's pet owl, Sir Hoots-a-lot, speaks for her in lieu of zombie moans.
  • You Gotta Have Blue Hair: In various shades.

Students, etc.


     Abbey Bominable
Voiced By: Erin Fitzgerald
Daughter of The Yeti. A foreign exchange student from the mountains who tends to unintentionally insult other monsters with her awkward grasp of the English language, along with other culture clashes.
  • Action Girl: Abbey is one of the most athletic and physically strong girls in school.
  • Amazing Technicolor Population: Her skin is light blue. And sparkly.
  • Asian Speekee Engrish: Subverted; people worried she'd end up like this when her diary was released because she's from the Himalayas and speaks broken English, but Erin Fitzgerald gave her an accent reminiscent of the Heavy instead.
  • Bishie Sparkle: If you're wondering, it's ice.
  • Brutal Honesty: She's never afraid to speak her mind.
  • Contralto of Danger: Stockiest of the ghouls with a deep Russian accent.
  • Cute Bruiser: Abbey is a white-haired girl with fluffy arm and leg warmers, a very slim build... and she can tie a metal horseshoe in a knot with her bare hands.
  • Cute Little Fangs: Tusks!
  • Deadpan Snarker: Usually less due to actual sarcasm rather than to her personality. See Dull Surprise and Malaproper.
  • Defrosting Ice Queen: With Mari in Monster Picchu. Abbey urges Mari to get to the train for Monster High, but as they become increasingly derailed by their adventures, Abbey starts to have more fun, and ends up staying behind for an extra week and taking over Mari's vlog in the meantime.
  • Elemental Hair: White and blue, ice powers.
  • Exotic Eye Designs: Her reboot design includes eye reflections shaped like seven-pointed stars.
    • Her Sweet Screams doll has starburst designs in her irises.
  • Dull Surprise: "Of course I am excited. Can't you tell?"
  • Fish out of Water: Or rather out of ice.
  • Hairy Girl: The reboot gives Abbey some molded fur like her cousin Mari's.
  • Huge Schoolgirl: Easily towers over most of the rest of the female cast. This is not the case with her dolls, which are the standard height.
  • An Ice Person: She can freeze things with a touch, and she constantly has snowflakes trailing after her.
  • Ice Queen: Naturally enough, yet subverted; she just unintentionally gives this impression with her words often being short, sharp, and hurtfully direct. She explains in her profile that this is because talking is "an oxygen waste" in the freezing climate of her native home, causing a lot of them to conserve oxygen and words by being more direct.
  • Literal-Minded: Was this when first arriving at Monster High, but has been growing out of it over time.
  • Malaproper/Dull Surprise: Due to "Yetish" being her first language and English being her second.
  • Mother Russia Makes You Strong: Her voice and personality fit the trope even though she's supposed to be from the Himalayas.
  • Multicolored Hair: Blue, purple and pink (occasionally purple) streaks, as if to mimic the Northern Lights, on her otherwise white hair. Her reboot's party doll goes with a darker palette, and as such, her hair streaks are only blue and purple.
  • My Nayme Is: It's spelled like the monastery, not like "Abby", which is likely to make a Stealth Pun on her Himalayan origins.note 
  • Mystical White Hair: Her dominant color, and she's the daughter of a mysterious snow-beast.
  • New Transfer Student: For a while.
  • Pointy Ears
  • Poor Communication Kills: Pretty much her shtick.
  • Pretty in Mink: Her basic dress is trimmed with white fur, paired with a white fur headband. Many of her outfits flaunt fur in some way, most likely a holdover from living 24/7 in a mountain range.
  • Proud Warrior Race Girl: Subverted: yetis aren't really a warrior people, just really tough.
  • Purple Eyes
  • Ship Tease: With Heath, bordering on being an Official Couple.
  • Sugar and Ice Personality: In spades.
  • Worthy Opponent: During the frequent sleepover game of "Gargoyles to Gargoyles" to which she is new, Abbey ignores the ghouls' suggestions to let Cleo win. When she finally wins, Cleo stands up in shock...only to reveal that she's glad she's finally found someone worth playing against, and challenges Abbey to another game.

     Spectra Vondergeist
Voiced By: Erin Fitzgerald
The soft-voiced, but not necessarily soft-spoken daughter of ghosts. Introduced as a ruthless and tricky gossip columnist who maintained the "Ghostly Gossip"; she was shown to be misunderstood of the influence of her column, but kept it up. As of Haunted she fully saw the harm rumors could cause, and decided to become a trustworthy journalist. She renamed her column the "Gory Gazette" following this change.
  • A Day in the Limelight: In the special Haunted.
  • Amazing Technicolor Population: White in the extremities, with transparent limbs.
  • Arc Villain: She's the primary antagonist of the Ghostly Gossip arc in the second season of the webisodes, causing much problems for the heroes/protagonist.
  • The Atoner: Implied with the ball-and-chain motif (see Shout Out). While it isn't clear what her "crimes" may have been, Spectra says in her profile that she "find[s] that it's unhealthy to focus on what one does wrong especially when contrasted with all the good one does in the unlife."
  • Chained by Fashion: Every doll of hers heavily features chains and shackles. Her Ghouls' Getaway release gives her chains made out of bamboo links.
  • Exotic Eye Designs: She has purple sclerae to make her especially eerie.
  • Goth
  • Heel–Face Turn: From a malicious gossip to a dedicated, kind, and heroic trustworthy news source.
  • Hidden Depths: In Clawd's first diary, she features as a nuisance twisting rumors to attack him. It's shown in her own first diary with Ghoulia that she actually had a pretty rough familial past, left unclear for now. In the short story that comes with her figure, it's revealed that the reason she became a gossip was to deal with the stress she got from moving schools from Haunted High to MH.
  • Invisibility: Well, she is a ghost. It comes in handy when you're the school's resident gossip.
  • Malicious Slander: Subverted, and Played With. In the webisode and CG special storyline Spectra never intended for her gossip column to harm anyone; she was just fascinated by the lives of the other ghouls and wanted to share their exploits with others, but was too shy to ask them for permission...or to ask them for the whole story, leading to a lot of misunderstandings from her only getting pieces of the story and then using her imagination to fill in the rest. In the diary storylines, she's a borderline-pathological liar who doesn't care if what she writes harms others— and gets ticked if people confront her about writing incorrect stories.
  • Multicolored Hair: Typically a blend of royal purple with lavender.
  • School Newspaper News Hound: Was this as the gossip columnist, and still this now.
  • Same Character, but Different: Her doll persona/diary narrative is a stark contrast to her webisode identity - Diary Spectra is malicious, rude and a pathological liar while her webisode/TV special identity is actually as soft spoken and sweet as her profile claims.
  • Shout-Out: Her ball-and-chain motif is similar to the chains that Jacob Marley's ghost wore as a representation of his earthly sins.
  • Shrinking Violet: While her gossip column is famous, Spectra herself is painfully shy. This is further alluded to with her character's mostly-purple color scheme. Following heavy Character Development she's a lot more outspoken now.
  • Supernatural Is Purple: One of her main colors, and she's sported all shades and hues of the color.
  • Technicolor Eyes: Blue, with purple sclera.
  • Techno Wizard: Not even Ghoulia can hack into her blog!
  • "The Reason You Suck" Speech: In Haunted, she gives one to Revenant.
  • Unreliable Narrator: Being the school gossip hound, she has this in spades. For example, while she claims in her first diary that she was once a royal, there's no way to tell if that's fact or fiction.
  • Villainous Cheekbones: Played straight for her diary personality, averted for all other forms of media.
  • Vocal Dissonance: Her soft, childlike voice highly contrasts with her angular features and chained up punk style.
  • The Von Trope Family: Her surname, with their components separated, would be "Von der Geist." This may or not be credence to her "descendant from nobility" story.
  • You Gotta Have Blue Hair: Violet with a hint of lavender. Her swim doll gives her blue highlights.

Voiced By: Cindy Robinson
Daughter of The Phantom of the Opera. A bodacious character with a rockabilly style (think the 50s, but goth), she's a skilled musician— shown to skillfully play piano, violin, guitar and banjo. Tends to do her own thing most of the time, and won't hang with monsters unless they earn her respect.
  • Amazing Technicolor Population: Purple.
  • American Accents: Sports a southern accent with a noticeable drawl. It's justified by Word of God as her parents moved from France to New Orleans when she was little.
  • Brown Note: She notes in her profile that her singing drives monsters crazy when they hear it live.
  • Cool Mask: Operetta has several types of heart-shaped face masks, which cover the left side of her face as a fashion statement. Her Frights, Camera, Action outfit trades out the eye mask for a fascinator with a veil that covers her scars.
  • Cool Pet: Daddy-o Longlegs, her guitar playing pet spider.
  • Cool Shades: Her Frightseers doll gives her purple crystal-encrusted sunglasses, with the crystals more heavily concentrated on the right in an abstract music note to hide her scar.
  • Early-Bird Cameo: Her first mention was in Holt's diary. She's reappeared in Spectra's diary and Cleo's 2nd edition diary.
  • Fiery Redhead: She doesn't take well to being threatened, nor being talked about behind her back.
  • Good Scars, Evil Scars: Has scars along the left side of her face patterned like swirling musical staffs around a treble clef, which go down to a spider web formation on her shoulder. Like her father, she usually covers the left side of her face. Unlike her father, it's not out of shame, but to make a fashion statement.
  • Gone Horribly Right: After overhearing Cleo insulting hernote , she plans to reaffirm Cleo's suspicions about Deuce and break them up by feigning a relationship with him. Once she talks to him, though, and realizes their genuine affection, she decides to help Deuce instead by writing a song to Cleo to help him express his feelings. However, Spectra appears and snaps a picture of the two going to Operetta's catacombs, causing the original plan to go into effect anyway.
  • Make Me Wanna Shout: Shatters a crystal idol with her voice in "Monster Mashionals Part 2", windows in Frights, Camera, Action, and "Uncommon Cold" shows that even her sneezes can be supersonic.
  • Meaningful Name: An operetta is essentially a smaller-scale opera production, fitting for the daughter of the Phantom.
  • Multicolored Hair: Red and black across all of her dolls, with the green streaks on her Roller Maze doll being the only exception.
  • Official Couple: With Johnny Spirit as of Haunted.
  • One of the Boys: May be this, as she says her best friends are Deuce and Holt.
  • Only One Name: Only goes by "Operetta", not even something like "Operetta Phantom".
  • Our Ghosts Are Different: In Haunted it's shown that phantoms and banshees count as ghosts and are thus susceptible to "detention chains", chains which cannot be destroyed but merely transferred and only worked off if the original chain-ee (Revenant) does good deeds.
  • Ship Sinking: She went out with Holt in the diaries, but because of Holt's temper, it didn't last long.
  • Symbol Motif Clothing: Piano keys, dice, vinyl records, and spider webs provide the majority of the patterns on her outfits.
  • The Fifties: Dresses in a retro/rockabilly style, and her "Frights, Camera, Action" outfit is influenced by the golden age of Hollywood.
  • The Rival: Cleo initially sees her as this when it comes to Deuce, but Operetta isn't into him.
  • Two-Faced: Like her father, she has scars down the left side of her face and body. While she does wear facial accessories like her father, hers are intended to accentuate and bring attention to her scars.

     Toralei Stripe
Voiced By: America Young
A werecat who was introduced in the first episode of Volume 2. Her initial story was that when she got tired of Cleo's perfectionist attitude, she and the Werecat Twins left the fearleading squad, and later after seeing how well the squad was doing with Frankie, Draculaura and Clawdeen, she tried to rejoin only to be rejected by Cleo. In the Monster Mashionals storyline, Toralei leaked the Monster High routine to their rivals Smogsnort's Vampiric Academy as revenge, but failed to make them lose. She's later re-inducted to the squad, but gets suspended for cheating on a test. Her and the ghouls butt heads once more in Why Do Ghouls Fall In Love and Boo York, Boo York...but it doesn't end well either time, thanks to Villain Decay. Now Toralei's just more of an occasional nuisance than an actual threat. Her online bio describes her as the personification of the mean girl with a posse.
  • Alpha Bitch: Bitchiness scale rating: under Nefera but above Cleo.
  • Big Bad Duumvirate: With Valentine in 'Why Do Ghouls Fall In Love?', and with Nefera in Boo York, Boo York.
  • Bilingual Bonus/Meaningful Name: "Tora" means "tiger" in Japanese.
  • Bitch in Sheep's Clothing: Based on her artwork, you'd never guess just how malicious she can get.
  • Catch Phrase: Frequently prefaces things with "mrowww".
  • Cats Are Mean: Her crowning moment is stealing Cleo's routine at fearleading camp.
  • Cats Hate Water: Being a werecat, she really doesn't like water. Great Scarrier Reef reveals that she can't swim, and she's not at all happy when she gets turned into a mermaid since it means she's surrounded by water.
  • Cat Girl
  • Dartboard of Hate: In a Freeze-Frame Bonus from Great Scarrier Reef, Toralei is shown to have one of Cleo in her locker, along with two photos with the mummy girl's face Removed from the Picture.
  • Disproportionate Retribution: Toralei has a habit of taking of her revenge schemes too far.
  • Dreadful Musician: Her singing voice literally stops traffic. Toralei has a mix of awareness and not-caring on the matter, since she knows to win the Fierce Rockers vote by being nice to everyone, but deliberately unplugs the rigged mic that was supposed to auto-tune her voice.
  • Even Evil Has Standards: Stopped Nefera from cheating—also partially out of revenge for Nefera's lack of trust in the werecats' fearleading skills.
  • Fiery Redhead
  • Good Scars, Evil Scars: Her left ear is notched, probably as a result of a fight.
  • Hell-Bent for Leather
  • Hidden Depths: Her diary reveals why she has animosity towards Cleo and showcases her softer side. Not a complete sweetheart, but nicer than one would expect.
  • Hypocritical Heartwarming: This is why she participates in the supportive speech about Lagoona in Great Scarrier Reef. She doesn't like Kala picking on Lagoona, but she can.
  • Ironic Name: "Lorelei" refers to a siren-like being with a beautiful singing voice. Toralei's singing voice is a horrendous yowl.
  • Laser-Guided Karma: Often.
  • Multicolored Hair: Usually just shades of orange with black stripes, but Freaky Field Trip has a blue streak, Freak du Chic is dark red with purple and black streaks, and Fierce Rockers has a solid black streak.
  • Oh Crap!: In Boo York, Boo York, she has this when she realizes the ghouls have followed her to Bloodway to retrieve the voice-holding comet crystal.
  • Only in It for the Money: Before thinking of taking the voices out of the crystal, the main reason she stole it was for a cash reward.
    -honked at loudly to stop-
  • Orange/Blue Contrast: Her Freaky Field Trip and Fierce Rockers dolls play on this, with blue accents contrasting her very orange colors.
  • Our Werebeasts Are Different
  • Out-of-Character Moment: In the time period leading up to Catty Noir's charity performance (where a lucky monster is nominated to sing alongside her), she notices that Toralei is being extra nice to everyone. She fails to realize that this is a ploy on Toralei's part to win the popular vote and get a chance to sing with Catty.
  • Passionate Sports Girl: In "Field of Screams", the Ghoul Sports tie-in, she's shown to be an ace at every sport. She's no team player by her own admission and mocks the ghouls initially, but when an opponent tries to say she can't play the claws are out.
  • Pet the Dog: During the Mashionals, as mentioned above. Also, her diary relates how she secretly helps a troll girl at Math Camp.
  • Pungeon Master: She makes at least one cat pun in every webisode she appears in.
  • Small Name, Big Ego: A key trait of hers is that she's afflicted by overconfidence. When it comes to singing, she won't take any substitutions but her own voice, despite its awful sound.
  • Spell My Name with an "S": Sometimes her name has been mistakenly spelled as Torelei.
  • Tightrope Walking: Her role in the Freak du Chic. Since she has innate feline balance, she's a natural, which she is quick to rub in her struggling fellow performer's faces.
  • Unusual Ears: Pointed cat ears on top of her head.
  • Voice Changeling: One of her special monster talents is perfectly mimicking anyone's voice and inflections. (i.e. she's a copy-cat.)

     Purrsephone and Meowlody
Voiced By: America Young
Purrsephone & Meowlody, otherwise also known as the Werecat Twins, largely exist as a silent girl posse for Toralei.
  • A Day in the Limelight:
    • In the special webisode, "Games Ghouls Play," with a pair of weremouse-twin brothers.
    • Meowlody gets a solo release in the "Ghouls' Getaway" line without Purrsephone and Toralei.
  • Always Identical Twins: Aside from the hair and their leg markings being on opposite legs. All of their outfits are alternately-colored versions of the other's. Played more straight in the webisodes; they do little more than smirk at Toralei's shenanigans.
    • Averted in the diary. (See single-minded twins below.)
  • Birds of a Feather: They're listed as friends of all of the werecats.
  • Cat Girls
  • Colour-Coded for Your Convenience: In their single diary, Meowlody writes in black ink, while Purrsephone writes in blue ink.
    • Meowlody's white-haired. Purrsephone's the brunette.
  • Cool Scooter: The Wheelin' Werecats playset reveals they share one.
  • Girl Posse: To Toralei. They think of her as a sister.
  • Multicolored Hair: Both of them have a black-striped white streak, but Purrsephone's hair is primarily black, and Meowlody's is mostly white.
  • Punny Name: Purrsephone is a reference to Persephone of Greek myth, and Meowlody is a feline twist on "Melody".
  • Single-Minded Twins: Averted via the diary showing their differences: Purrsephone is slightly less likely to prank and has a desire to break away from her sister while Meowlody is much more chaotic and slightly more dominant.
  • Suddenly Voiced: Up until Great Scarrier Reef, their spoken lines were limited to meows or hisses. Then, near the end...
    Purrsephone: So mice to be able to talk now that Toralei is gone.
    Meowlody: Yeah, she always hogs the converrrsation.
  • Those Two Guys: Little to no dialogue between them.

     Nefera De Nile
Voiced By: Wendee Lee
Cleo's malicious older sister who rejoices in asserting her authority over her younger sister and anyone else around. Along with Ramses De Nile in Boo York, Boo York, she seeks to establish a dynasty with the Ptolemys to gain fabulous wealth and power—at the cost of Cleo's happiness with Deuce.
  • Alpha Bitch: Even Toralei and Cleo cannot compare to Nefera's bitchiness.
  • Big Bad Duumvirate: With Toralei and Ramses De Nile in Boo York, Boo York.
  • Big Sister Bully: Very clearly enjoys tormenting Cleo and, based on how Cleo reacts to her, always has.
  • The Cheerleader: Was this during her tenure at Monster High—she was even the captain before passing the reins onto her sister.
  • Early-Bird Cameo: First mentioned in Clawd's first and Cleo's second diaries before making an appearance in the webisodes.
  • Establishing Character Moment: After making a grand entrance, she taunts and then blackmails her sister into doing her bidding after finding out about the party thrown behind their father's back. This is all within about ten seconds.
  • Foil: To Cleo de Nile: she's an example of what her younger sister could have been if she hadn't gained a sense of compassion.
  • The Glorious War of Sisterly Rivalry: Again, with Cleo. Even pushed forward by her father.
  • Laser-Guided Karma: In "Monster Mashionals Part 2" Nefera uses the family idols to get her team of fearleaders to win, but this prompts the catgirls to help Cleo as they learned their lesson from last time and wanted to win fairly this time around. Ghoulia shows Scary Murphy a video of Nefera cheating, and in turn Nefera is stripped of her previous awards, causing her to give an anguish-filled, glass-shattering scream in defeat.
  • Make Me Wanna Shout/Glass-Shattering Sound: When Ghoulia exposes her cheating to Scary Murphy, this is her reaction to Scary Murphy's judgment against her. And her scream in Boo York, Boo York makes the entire gala look at her.
  • Missing Mom
  • Multicolored Hair: Teal in all releases, with varying accents.
    • Gold and black in her signature release.
    • Black, silver, and copper in her Boo York, Boo York release.
    • Purple streaks for her Scream and Sugar doll.
  • Purple Eyes
  • Rich Bitch: She puts Cleo's early nastiness to shame, and is shown in Boo York, Boo York to still not be satisfied with her massive wealth.
  • Seductive Mummy
  • Villainous Widow's Peak: This is her hairline, and she's definitely a nasty piece of work.
  • Villain Song: She shares one with her father in Boo York, Boo York.
  • You Gotta Have Blue Hair: Turquoise, black and gold streaked.

     Howleen Wolf
Voiced By: America Young
Howleen is one of the many younger siblings in the wolf family and shares a room with Clawdeen. After being mentoned several times in diaries, she officially made her appearance in the second Monster High TV special Fright On. She was released as a doll in a 2-pack with Clawdeen in early 2012.

     Rochelle Goyle
Voiced By: Erin Fitzgerald
The daughter of Scarisian gargoyles, she's incredibly protective of her friends.
  • Curtains Match the Window
  • Cute Bruiser: A pastel style and a lilting french accent, and hard to beat on a roller derby maze track... for monsters.
  • Living Statue
  • Meaningful Name: "Roche" is French for "rock". It also means "Peace", which is appropriate for a protector monster.
  • Multicolored Hair: Pink hair with aqua blue streaks, though Ghoul Chat has much lighter shades, Zombie Shake has a black streak, and Love In Scaris is mint green and pastel pink.
  • Older Than They Look: She's 415. Gargoyle aging!
  • Smitten Teenage Girl: In her diary, she develops a crush on Deuce after he accidentally runs into her and, after getting his sunglasses knocked off, explains that his stone gaze does not work on gargoyles and basilisks. She knows that Deuce and Cleo are an item, but this does not stop her from getting her pet, Roux, to steal Deuce's casketball in order to lure Deuce to her. Though nothing more than talking occurred between Deuce and herself, Rochelle does admit to feeling somewhat guilty afterwards. She's reunited with her actual boyfriend, Garrott Du Roque, in Scaris: City of Frights.
  • Technicolor Eyes: Pink.
  • Winged Humanoid
  • Gold Pin Of Power: In "The Halls Have Eyes", Rochelle is appointed with the position of Safety Monitor, and grapples with its' responsibilities when she feels like she's actively being a killjoy. It turns out her proactivity and dedication promoted her to leader of the school's Safety Team... which consists of Heath, Manny and Slo Mo.
  • Your Cheating Heart: Subverted. Briefly crushed on Deuce despite having a boyfriend (Garrott) still in Scaris— but he'd long since stopped writing her, so in her mind he'd left her.

     Venus McFlytrap
Voiced By: Julie Maddalena, Cassandra Lee (Welcome to Monster High)
Daughter of the Plant Monster. By her own description, she's a nature-loving eco-punk — which makes sense, considering her scaritage. Dedicated to promoting recycling and going green.
  • Amazing Technicolor Population: She has bright green skin.
  • Brainwashing for the Greater Good: Can inflict a mild form of this on fellow monsters (see her Jedi Mind Trick section for more info)
  • Cute Little Fangs: Comes with being a carnivorous plant. Curiously absent in CG.
  • Elemental Hair: Green streaks, plant powers.
  • Freaky Fashion, Mild Mind: Well, relatively so. Despite her punk-rock fashion sense, Venus is surprisingly mild-mannered and peaceful, though definitely passionate and loud when it comes to saving the planet.
  • Green Thumb: Has been shown to have an ability to magically grow and nurture plants on a few occassions. At other times she's seen caring for plants, Venus will be seen using ordinary gardening methods, at which she still seems to be excellent.
  • Granola Girl: She's obsessed with saving the environment. Howleen slightly fears her eco-spiels.
  • Jedi Mind Trick: She can use her "Power of Pollen Persuasion" to get others to do her bidding. However, she can only affect one monster at a time. (Unlike Batman's Poison Ivy, this works on all monsters, not just ones attracted to her.)
  • Man-Eating Plant: Her monster type, with sharp fangs and plant-like attributes. She does stick pretty close to the real-life inspiration for such monsters, though.
  • Multicolored Hair: A mix of lime green and hot pink to match her namesake. The shaved part of her head indicates that the dominant color is pink. Some releases add black to the mix, her Fierce Rockers hair is medium pink with a lighter streak, and "Electrified" gives her a yelllow streak instead of green.
  • Plant Person: Has sharp flytrap teeth, leaf ears, vine accessories (the vines are molded on post-reboot), and bark-textured hands.
  • Rapunzel Hair: Her signature doll's hair falls below her waist.
  • Talking to Plants: She does this constantly, talking to trees even after they've been processed into paper.

     Robecca Steam
Voiced By: Julie Maddalena
The robot daughter of a missing Mad Scientist, and extremely proficient with her rocket boots.
  • Ambiguously Brown: At first glance she appears to be brown-skinned, until you realize she's a robot and her "skin" is actually riveted copper plates. Yet her father is implied to be Desi, so isn't a stretch to think she is too.
  • British Accents: She and her father have them, to complete the Victorian theming.
  • Call Back: The patterns on her Gore-geous Accessories dress are mechanical sketches for her Art Class welding mask and robot clock.
  • Clockwork Creature: Even her eyes are cogwheels.
  • Cute Machines: She has an adorable pet mechanical penguin named Captain Penny.
  • Disappeared Dad: Her father is Hexiciah Steam, a mad scientist who went missing during an expedition a hundred years ago, though it's implied he may be still alive. She gets to briefly meet him again (from the past) in Freaky Fusion.
  • Everything's Better with Penguins: Has a robot one for a pet.
  • Exotic Eye Designs: Her irises are gears.
  • Happily Adopted: Lives with Kindergrubber, the Home Ick teacher at Monster High.
  • Jet Pack: She has rocket boosters built into her high-heeled boots — and enjoys performing daredevil stunts with them.
  • Mad Scientist's Beautiful Daughter: Yes, she is, but with more daredevil traits than the traditional type.
  • Living MacGuffin: The Vampire's Heart (the artifact that decides the rulers of the vampires) was built into her chest by Hexiciah.
  • Multicolored Hair: Black with blue streaks. Her Art Class doll adds a little bit of purple.
  • Nice Hat: Her Dance Class outfit has a headband with a tiny top hat on it. Her Frights, Camera, Action!/SDCC outfit has an large blue top hat.
  • Nice Job Breaking It, Hero: In Frights, Camera, Action: leaving the book marking all the ghouls' destinations out for Lord Stoker to follow was not very bright.
  • Older Than They Look: Robecca's creator designed her to look like a teenager—116 years ago.
  • Ridiculously Human Robot
  • Steampunk: In both her body design and her fashion sense. Justified, seeing as she was built during the Victorian era.
  • Tuckerization: Named after a character designer for the series, Rebecca Shipman.
  • What Measure Is a Monster?/Do Monstroids Dream?: Her diary reveals that she has been exposed to some Fantastic Racism during the party at Draculaura's, courtesy of some goblin.

     Wydowna Spider
Voiced By: Erin Fitzgerald
Daughter of Arachne. Introduced playing a semi-villainous role in the Polterghoul's story.
  • All There in the Manual: The webisodes and movies make no effort to characterize her or even include her for the most part, meaning that her diary is the most information one can get about her.
  • Amazing Technicolor Population: Stark black, #000000.
  • Arachnid Appearance and Attire: NO, really?
  • Artistic License – Biology: Refers to having hearts in the plural, even though spiders have one heart, like humans.
  • Cute Little Fangs: Black ones!
  • Dark Is Not Evil: Look at her, then read her bio. Different than you might expect, right?
  • Extra Eyes: Has two pairs of insectoid eyes above her main ones.
  • Fangirl: Describes herself as a "fanghoul at hearts" and dresses in a "rock 'n' roll geek" style.
  • The Fashionista: Makes her own clothing, and is willing to make outfits for her friends.
  • Multi-Armed and Dangerous: Has six arms and is a villain in her first appearance.
  • Mythology Gag:
    • Arachne was an arrogant weaver whose skill and blasphemous attitude and artwork enraged Athena, and was punished by being turned into the first spider. Wydowna is a spider monster who reflects her mother's behavior by making her own clothes.
    • From the diary, we learn more about Arachne. Apparently, she once wove a tapestry predicting Bloodgood's failure, reflecting the versions of the myth that blame her curse on her offensive artwork, and she goes "way back" with Medusa, as both were cursed by Athena.
  • No Brows: Justified, since her six pairs of eyes (with only the bottom pair being humanoid) would complicate eyebrow placement.
  • Out of Focus: Her appearance must really spook some people, because she rarely shows up in animated materials. Appears heavily in the Ghoulfriends books, and that's... about it.
  • Never Heard That One Before: Hates when monsters make black widow jokes about her.
  • Punny Name: "Black widow spider" meets Winona Ryder.
  • Red and Black and Evil All Over: Subverted. Baddie in the comic, but a really nice ghoul.
  • Red Eyes, Take Warning: Six of 'em.
  • Shout-Out: Her dolls' middle left hand hand is posed in the web-slinging manner.
  • Spell My Name with an "S": Wydowna, not Widowna.
  • Spiders Are Scary: Her basic premise, taking visual cues from the black widow.
  • Symbol Motif Clothing: If you didn't guess "spider webs", then you must not have read the rest of this entry. Her outfits also tend to have comic-styled sound effect bubbles.
  • Trademark Favorite Food: "Fonboo" note , since her six arms make it easy to try different flavor combinations.
  • Visual Pun: Has a widow's peak hairline.

     Scarah Screams
Voiced By: Erin Fitzgerald (Webisodes), Paula Rhodes (Haunted)
Daughter of the Banshee. Possesses the ability to read minds; and can also communicate telepathically over long distances (albeit not well), as demonstrated in "I Scream, You Scream".
  • Actually Pretty Funny: Commends the gang on their Batman Gambit to set her and Billy up together, saying that "it's hard to surprise a telepath."
  • Alliterative Name
  • Amazing Technicolor Population: Bluish mint, which is nearly identical to Frankie's.
  • Ascended Extra: Originally a background character in the webisodes.
  • Journey to the Center of the Mind: Assisted by one of Ghoulia's inventions, her and the ghouls take one to Hoodude's head in "Undo the Voodoo" after her initial attempt to read his mind doesn't exactly work.
  • Make Me Wanna Shout: Her scream is bad news for any who hear it.
  • Multicolored Hair: A vivid green streak in her Ghoul Fair release.
  • Mythology Gag: She wanted to be an extra because when she does talk, bad things often happen.
  • The Not-Love Interest: To Hoodude.
  • Oireland: Justified, considering banshees originate from Ireland. She doesn't like it when people try to imitate her voice and she says she dislikes certain cereal-brand jokes that people bring up around her.
  • Official Couple: With Billy as of "Scarah-voyant".
  • Our Banshees Are Louder
  • Pointy Ears: Likely because banshees are fairy spirits.
  • Prophet Eyes: Her eyes are blank white.
  • Psychic Powers: She possesses telepathy, likely to explain how banshees in myth know about impending deaths.
  • Sensory Overload: This causes Cleo's plan for Scarah to telepathically tell her a Home Ick recipe to go wrong. There are too many students in the halls, and Scarah ends up transmitting some of their conversations, resulting in a catastrophic recipe in the classroom.
  • The '60s: All of her outfits are influenced by this era.
  • Symbol Motif Clothing: She doesn't have a single theme uniting her outfits, but her Student Disembodied Council dress is covered in pop-art screaming faces, and her Ghoul Fair car wash outfit is themed on green soap suds and splatters.

     Iris Clops
Voiced By: Paula Rhodes
Iris is a klutzy cyclops who's kind, poetic, and passionate about astronomy. She had a crush on Manny for a while, but was turned off seeing how bullheaded he usually was. After discovering his inner poet with the help of the Inner Monster app and getting to know him better, she realized his Hidden Depths and the two have been dating ever since. Her initial release was with him as a 2014 San Diego Comic Con exclusive two-pack.

     Jane Boolittle
Voiced By: Stephanie Sheh
Daughter of Doctor Boolittle. Helps to promote the "Secret Creepers" line of secret-hiding representations of the characters' pets, as she looks after and talks to them.
  • Amazing Technicolor Population: Purple skin, which may be a Visual Pun on her personality.
  • Ambiguous Disorder: Is terrified of social interaction and prefers the company of animals. She also has a scientific and observational mindset and makes the unconventional connection between monsters and wild animals to sort out her fears, perhaps indicating that she might be somewhere on the autism spectrum.
  • Awesomeness by Analysis: Turns out to have better social skills than she thinks, due to observing everything that goes on at MH and thus having information to talk about with others.
  • British Accents: As she was raised by British scientists, she has this.
  • Curtains Match the Window: Her Ghouls' Getaway doll. (See You Gotta Have Blue Hair.)
  • Darkest Africa: While not played as seriously as it would have been in the past, this is almost certainly where Jane comes from.
  • Facial Markings: Lines of blue dots under her eyes on her first two dolls.
  • Femme Fatalons: Her nails are very long, and her doll's hand mold is clawed (to be exact, it's the same mold as Rochelle and Clawdeen's). She herself isn't villainous.
  • Friend to All Living Things:Can communicate with animals, and loves to observe them.
  • Happily Adopted: By an Expy of Dr. Dolittle and his colleague, an expy of Dr. Moreau. Her true monster scaritage is unknown, as they found her at either 5 or 6 alone in the jungle.
  • Has Two Daddies: Depending on the gender of this universe's Dr. Moreau, Jane is implied to have been raised by two male scientists.
  • Improbable Hairstyle: In her "Ghouls' Getaway" release, part of her hair is tied back into a high ponytail that's gelled into a fan shape.
  • Innocent Blue Eyes
  • Irony: Although her theme is pets and animals, her own pet, Needles, doesn't appear in the webisodes.
  • Jungle Princess: This definitely contributes a bit to her theme and her name.
  • Lethal Chef: The reason Home Ick is her least favorite class. As she puts it, she can assemble the ingredients just fine, but trying to put them together ends in disaster.
  • Multicolored Hair: Deep indigo with red streaks in her signature release, and a lighter shade of purple with red streaks in her Gloom and Bloom release.
  • Nature Lover: Loves to explore the jungle, and thus is listed as a friend of Venus, Gilda, and Batsy.
  • Not Good with People: Yeah. Actually was crawling through the vents in her first few days at MH just to avoid interacting with other students. She's gotten better since, but won't completely be out of her shell for a while.
  • Pretty in Mink: Subverted. While she does have fur accents in her outfits, it's to convey a wild theme, rather than elegance.
  • Scary Stitches: Needles is a "voodoo sloth" stitched together. Given Jane's ability to communicate with him, it's likely he's made out of real sloth parts.
  • Shout-Out: Her first name is likely one to the Jane of Tarzan.
  • Shrinking Violet: She's so shy that at first she doesn't even go to class, preferring to hide in the vents and observe the goings-on at school. Eventually she becomes confident enough to come out in the open and become friends with the main ghouls.
  • Skeletons in the Coat Closet: While the colors imply that they're not real, she has a few bones and teeth in her accessories, and a belt of skulletes, as well as a skullette-topped staff. None of this is at all indicative of her personality, though.
  • Speaks Fluent Animal: Her "monster power", which she uses with the pets who have sneaked into Monster High.
  • Symbol Motif Clothing: Bones, feathers, and tribal skulls.
  • Vague Age: She's either 15 or 16.
  • Wild Child: It's how she knows how to talk to animals.
  • Witch Doctor: While her specific monster type is unknown, this is her theme. Her outfits are influenced by African tribal fashions, and include feather, bone, and skull accessories, and neck coils on her signature doll, and there are patterns of hands clutching mysterious plants on her Ghouls' Getaway dress. Her pet is a stitched-up voodoo sloth and she has the ability to talk to animals. However, due to being raised by scientists, her personality is that of a highly analytical junior anthropologist, studying the most mystifying creatures of all—high-schoolers.
  • You Gotta Have Blue Hair: In her Ghouls' Getaway release.

     Amanita Nightshade
Voiced By: Heather Moiseve
A plant monster born from the seed of the Corpse Flower, an extremely rare flower which only blooms every 1300 years, Amanita is very beautiful but also very selfish. She has a history with Cleo de Nile's family and Deuce's mother Medusa. She's the signature doll corresponding to the "Bloom and Gloom" line.
  • Amazing Technicolor Population: Tea green.
  • Artistic License – Biology: In real life, the corpse flower is simply a horrible-smelling flower (which is referenced in the webisodes). In this universe, it's also monstrous and its offspring is a humanoid girl.However, the flower itself and Amanita match its real-life colors, and Amanita's green skin makes her the center of the flower when it opens.
  • Birds of a Feather: With her past owner Nefera de Nile, as both are incredibly narcissistic and obsessed with their own beauty.
  • The Bus Came Back: After abruptly disappearing from the story, she gets a new doll with Nefera in the "Scream and Sugar" bakery line.
  • Elegant Gothic Lolita: Her outfits follow this theme, with purple and black colors and lace accents.
  • Green Thumb: In "Bad Tomb-mates" it's shown that she's able to manipulate vines. She uses this ability to escape the De Nile tomb. And leave the de Niles behind. It's also implied that she can summon or regrow the Corpse Flower when she feels like an extra-long nap.
  • It's All About Me: She seems honestly confused when people don't worship her and do everything she asks of them.
  • It's Personal: Cleo's grudge against her. She could have saved Cleo's family from the tomb but pretty much forgot about them entirely once she was out.
  • Jerkass: Gee, you think? Amanita's completely self-absorbed, and frequently "borrows" other peoples' things without ever returning them. She's billed as a "bad seed" for a reason.
  • Karma Houdini: Amanita's favorite trick, although she likely doesn't realize what she's doing is wrong. She abandoned the de Niles in their tomb without consequence, and 1,300 years later, she steals all of Draculaura's belongings and disappears from the series.
  • Narcissist: The thought of thinking about other's needs before hers seems like an utterly alien concept to her, to the point that it's almost a case of Blue and Orange Morality.
  • Meaningful Name: Amanita is also the name for the genus of some of the most toxic mushrooms in the world. Well fitting her toxic personality and "creepy plant" themenote .
  • Never My Fault
  • Older Than They Look: Has probably existed for millenia, but looks like a teen girl.
  • Only Friend: To Nefera while she and Cleo and their father were trapped in the tomb, and apparently resumes her companionship once she wakes up again. Also lists her BFF as "Amanita Nightshade", so she's apparently her own only friend.
  • Plant Person: A fancier version than Venus. She's the offspring of a corpse flower, and able to control plants including her own flower whenever she feels like resting.
  • Pointy Ears: Likely to evoke the shape of a leaf.
  • Shadow Archetype: To Cleo, as both are superior and think highly of themselves. Cleo cares about others, though, whereas Amanita only thinks of herself.
  • Sticky Fingers: Stole Cleo's clothes when they were both in the tomb, various makeup items from the other ghouls at varying times, and the entirety of the contents of Draculaura's huge closet, while in the same room as her and all of her friends.
  • Symbol Motif Clothing: Flowers and skeletal leaves are recurring patterns in her outfits.
  • Third-Person Person: Amanita writes in third person all the time in her diary and profile. It's probably because she feels the narration is more dramatic in third person, but more likely is that she loves the sound of her own name. She speaks in first-person, however.
    You want Amanita to run? Oh no no no! Monsters run to Amanita Nightshade or for Amanita Nightshade. Amanita does not run.
  • 13 Is Unlucky: She sleeps for 1,300 years, and she's a negative force among the cast.
  • Unwanted False Faith: Completely averted. When other monsters mistake her for a goddess, she happily accepts their worship.
  • Valley Girl: Speaks with this accent.
  • What Happened to the Mouse?: Disappears shortly after her introduction, though nobody was likely to miss her. Averted as of her second release in the Scream and Sugar line, which shows that she's decided to stick around.
  • You Gotta Have Blue Hair: Violet with some blue and magenta highlights.

     Casta Fierce
Voiced By: Kate Higgins
Daughter of Circe, and a famous pop star in the monster world. When her nerves overtake her while singing live she's prone to flubbing lyrics, which throws out accidental hexes on her fans. It happened so often that she now only sings live once a year, on Halloween (and doesn't get a pet because everyone would say it was an ex-fan). The webisode "Casta Vote" shows the venues for live performances are decided by online vote, and Monster High gets picked. She officially performs at Monster High on Halloween 2014, and the ghouls help her lose her stage fright with help from an interrupting Toralei.
  • Amazing Technicolor Population: Green skin, in reference to the old trope.
  • Baleful Polymorph: This is what happens to her fans when she makes a mistake in her songs. The mansters ask for this at the end of "I Casta Spell On You", and get turned into love bugs with little top hats!
  • Classical Mythology: Circe, her mother, was a sorceress in Greek mythology who held up Odysseus and turned his men into pigs. Hence Casta's Mythology Gag of turning monsters into animals.
  • Everything's Better with Sparkles: She loves glittery outfits and accessories, and her dress is almost completely covered in glitter.
  • Exotic Eye Designs: Purple, with orange starbursts around the pupil.
  • Facial Markings: She has a small gold slash coming down from her right eye.
  • Femme Fatalons: Has clawed fingers, as witches tend to do.
  • Generation Xerox: As "Casta Vote" shows, she possesses the same hair color, skin color, immense beauty and immense talent of her mother.
  • Hell-Bent for Leather: Her ensemble includes a strappy studded leather neck harness complete with shoulder cages, and purple leather high heel booties. She's no baddie, though.
  • Hot Witch: Tall, beautiful, and vivacious, with a body-hugging Halloween-styled outfit.
  • Innocently Insensitive: Genuinely thanks Toralei for providing the distraction she needednote  to stop overthinking her lyrics. However, to Toralei, her idol Casta essentially thanked her for humiliating herself in front of everyone.
  • Multicolored Hair: Black with a streak of orange and purple each. Apparently natural, as she had them when she was a child.
  • Mythology Gag: Her friendship with Catty Noir. Not only are they fellow pop stars, but black cats are most well-known for being witches' companions.
  • No Celebrities Were Harmed: Based pretty transparently on Beyoncé, with Casta's name mimicking Beyoncé's one-album alter ego Sasha Fierce and Casta's hairstyle taken from the "Single Ladies" music video.
  • Periphery Demographic: In-universe. The mansters are unashamedly as into Casta as the ghouls are, becoming instant fans, and they provided the necessary final votes to get Casta to perform at Monster High.
  • Pointy Ears: To emphasize her magical qualities, and also reference the traditional wicked witch look.
  • Power Incontinence: Simply invoking an animal in her lyrics is enough to turn her audience into whatever creature she accidentally referenced.
  • Rapunzel Hair: It hangs just below her bottom.
  • Scary Musician, Harmless Music: Wears an over-the-top rock outfit and her doll's face especially lives up to her name, but her music is bright pop with some rap-like verses before the chorus.
  • Shout-Out: The belts and ribbons tied to her mic stand are a reference to Steven Tyler tying scarves to his microphone stand.
  • Signature Song: In-universe, "The Witching Hour."
  • Statuesque Stunner: Taller than the rest of the cast, with the Big Sister doll mold.
  • Teen Idol: Toeing the line—she's 19.
  • Wicked Witch: Her mother Circe plays with this by having the traditional green skin, but otherwise, she looks like the Ancient Greek sorceress she is. Casta herself puts a pop-star twist on the idea, but still retains the classic buckles, boots, clawed fingers, pointed chin, and wart.

     Gooliope Jellington
Voiced by: Julie Maddalena
A giant goo girl adopted by circus folk. More comfortable there with the circus folk than in the outside world where she's odd even by monster standards, she nevertheless ends up at Monster High. The online bio describes her as the personification of a girl that feels like an outsider. Not inspired by any particular monster, but a spiritual descendant of creatures like The Blob. Signature doll of the Freak du Chic line.
  • Amazing Technicolor Population: Made of shimmery pink goo.
  • The Bus Came Back: Existed largely to justify the Freak du Chic line, and was seemingly dropped afterward, but she makes a return in the Shriek Wrecked line.
  • Circus Brat: Raised by the circus; in her diary she also talks about the trope of The Runaway who wants to join the circus, saying they wouldn't be so eager if they knew how much downtime and hard work goes into being part of the show.
  • Doorstop Baby: Of a sort.
  • Exotic Eye Designs: The reflections in her eyes are shaped like radioactive trefoils (☢). Her eyelashes are curled in loops with dot accents above them as well.
  • The Freakshow: Her circus family includes some that are considered "freaks" even by other monsters. She hates it when they're treated as such though.
  • Gentle Giant: A giant goo monster. Despite her size, she feels very shy and out of her element when not performing in the Freak du Chic.
  • Gold Makes Everything Shiny: All of her jewelry and accessories are gold.
  • Happily Adopted: By the ringmaster and all the circus folk. They treat her like family (and throw the occasional prank). Even though she's happy, she does still wonder about where she came from, and has cried over the note from her scientist creator.
  • Hey, Let's Put on a Show: Helps the ghouls put on Freak du Chic to raise enough money to save the school's arts programs.
  • Huge Schoolgirl: Even by Monster High standards: she's 15 feet 2 inches. A photo posted by MH shows her keeping track of casketball scores, so it's safe to assume she plays and gives a huge advantage to her team.
  • Large and in Charge: Takes the role of ringmaster in the ghouls' act, and is the biggest character yet.
  • Mad Scientist: R.S., the person who created her and gave her up for adoption.
  • Meaningful Name: Named after the calliope, or steam organ, which is responsible for a lot of circus music, particularly of the creepy variety, and goo.
  • Monster Clown: She's a circus ghoul who knows all the tricks and is a skilled acrobat, with bouncy multicolored hair.
  • Multicolored Hair: Gold, with a pink undertone. Shriek Wrecked makes the dominant color a rich blue with a streak of gold and orange in the front.
  • Nice Girl: Helps the Monster High ghouls save the arts program at their school out of sympathy for the cause, encourages them when it seems like their show is doomed to fail; she won't even choose a pet for herself because she doesn't want to make the rest of the circus creatures jealous. Her "Personal Monstra" is to understand other monsters because she empathizes with feeling ostracized due to her attributes.
  • Nice Hat: Headbands, rather.
    • Signature has a headband of a monstrous calliope organ with piano-key teeth and screaming pipes for hair.
    • Shriek Wrecked gives her a headband of a steamship with a shark face on its hull.
  • Nice Shoes: Signature Gooliope's shoes have skeleton carousel horses for heels.
  • Not Drawn to Scale: Her signature earrings are supposed to be real wagon wheels, but when placed next to the in-scale standard dolls, they're only about the size of a dinner plate.
  • Not-So-Forgotten Birthday: Her sixteenth birthday goes completely unnoticed, until the emergency alarm sounds during Gooliope's pity party. It turns out that she's been summoned for a surprise party with gifts from everyone at the circus.
  • Punny Name: As usual for Monster High, but also applies to her original number names - Experiment 816 = BIG, and Batch 8708 = BLOB.
  • Quirky Curls: Curly hair, and she's an acrobatic contortionist circus ghoul with a trend towards the performative.
  • Rousing Speech: Delivers one to the discouraged ghouls when they think they won't perfect their acts in time.
  • Scavenged Punk: This is part of her style, as her size necessitates the re-purposing of objects to create her outfits. For her first outfit, her dress is made out of tent fabric, her earrings are wagon wheels, she has epaulettes recycled from a test-subject collar, and her headband is made of organ parts. The other pieces of her outfits are made to invoke this, but due to their scale, prove to be sized-down replicas of the original objects.
  • Shout-Out: Part of her box art references Attack of the 50-Foot Woman.
  • Shrinking Violet: Oddly enough. Despite her theatrical nature as a performer, Gooliope doesn't like to call much attention to herself off-stage. She notes that talking to 'normal' monsters makes her feel nervous.
  • Slime Girl: Her basic physical nature.
  • Statuesque Stunner: She's over 15 feet tall.
  • Symbol Motif Clothing: Radioactive trefoils in her first outfit, and dripping patterns in her Shriek Wrecked outfit.
  • Trademark Favorite Food: Due to her own composition, she enjoys gooey food such as jelly donuts, gummy candy, and boba (bubble tea).
  • You Are Number 6: Her original designation was Experiment 816, Batch 8708. The folks who adopted her gave her a more colorful name.
  • You Gotta Have Blue Hair: Her main color for her Shriek Wrecked release.
  • You Wouldn't Like Me When I'm Angry: In "Freak du Chic Act 3", it's shown that when she's mad, she involuntarily starts shaking hard enough to make the ground below her tremble.

     Gilda Goldstag
Daughter of the Ceryneian Hind, and Toyless Toyline Character until her release in the We Are Monster High 5 pack.

     Dayna Treasura Jones
Daughter of Davy Jones, and themed after pirates. Signature doll of the "Shriek Wrecked" line.
  • Amazing Technicolor Population: Golden skin.
  • Dressed to Plunder: Has a treasure-chest hat, a big dress, tall boots, and hoop earrings of emeralds carved into parrots on perches.
  • Exotic Eye Designs: Fitting her love of stars, her eyes have stars in them.
  • Gold Makes Everything Shiny: Her hair and skin are gold, her dress flips around to reveal a golden layer on the other side, her hat opens to reveal some coins, and her shoe heels can be removed to expose the golden-coin heels underneath.
  • Good Scars, Evil Scars: Her limbs are molded with engraved constellations.
  • Mythology Gag: Officially friends with Vandala and River—one a ghost pirate, and the other a teenage reaper. Fitting friends, since her father is the personification of where many pirates meet their end.
  • Odd Name Out: The only character thus far to be marketed with a middle name.
  • Pimped-Out Dress: The underlying layer qualifies with a Gem-Encrusted bodice, glitter and an elaborate golden pattern of gemstones.
  • Pirate Booty: Her hat, shoes, and dress all have a "hidden-treasure" theme. She even states in her bio that she likes her fashion how she likes her treasure—"shiny and jewel-y and gold, and a hint of mystery is always sea-sational!"
  • Pirate Girl: Naturally, being the daughter of pirates' greatest fear.
  • Spell My Name with an "S": Her name is spelled Dayna, not Dana, as preliminary materials showed.
  • Talk Like a Pirate: Her bio counts with liberal use of piratical turn of phrase as well as replacing 'my' with 'me'.
  • The Pirates Who Don't Do Anything: Though she's themed heavily after the traditional pirate, her bio states outright she can't stand thieves or thievery. Instead she prefers scavenger hunts, even if there's no treasure to be had—she prefers the adventure more than the treasure.
  • Treasure Map: The blue side of her dress has this theme, and her outer heels have an "X" to let you know they're removable.
  • Youthful Freckles: They're stars, a recurring symbol on Dayna.

     Zomby Gaga
A monster representation of Mother Monster herself. A special collector's doll designed by Gaga's sister Natali, produced for the Born This Way Foundation, and serving as the symbol of MH's "#KindMonsters" movement.
  • Amazing Technicolor Population: A very pale bone-like color. This isn't far off from the real Gaga's skin tone, though.
  • Badass in a Nice Suit: She's Gaga, after all, and she's wearing her flared-cuff/bell-bottom suit seen in "Born This Way".
  • Cool Shades: One of her accessories.
  • Dem Bones: She has the skeletal/zombie makeup from the "Born this Way" music video.
  • Exotic Eye Designs: Her eyes have heart-shaped light reflections.
  • Facial Markings: The aforementioned makeup/tattoos.
  • Femme Fatalons: Her fingers have sharp nails, which are shown off by the clawed pose of one of her pairs of hands.
  • Iconic Item: Her doll includes the bubble gum and sunglasses that appeared in "Born This Way".
  • Glasgow Grin: Part of the skeleton tattoos, like Skelita and River before her.
  • Lighter and Softer: Her facial makeup is considerably less extreme than the real Gaga makeup it's based on.
  • Multicolored Hair: A subtle blend of pastel pink and dusty lavender.
  • Nice Shoes: Tall platforms with wicked heels, based on her white shoes seen in "Telephone".
  • No Brows: To go with the corpse-like appearance.
  • Punny Name: Of Lady Gaga.
  • Stocking Filler: Her alternate outfit has fishnet tights.
  • Symbol Motif Clothing: The words "Born This Way" appear in the lining of her jacket and form the white stripes of her plaid dress.

Monster Exchange

Exchange Students General Tropes
  • Funny Foreigner: Downplayed. A lot of their foreigner tropes are more monster specific than analogous to anything in the real world, and they all act like everyday teenage girls. Of course, they still have their moments— like Mari's explanation of foot-centric maricoxi beauty standards.
  • New Transfer Student: This facilitates their arrival into the story, and episodes about them deal with the new ghouls settling into the school.

     Lorna McNessie
Voiced By: Marieve Herington
An exchange student from Rotland, she's a Loch Ness monster who loves photobombing.
  • Amazing Technicolor Population: Shimmery sea green with light blue fins.
  • The Clan: The monsters of Loch Ness seem to have these, and she's part of one.
  • Cute Little Fangs: They point upwards, like an anglerfish's.
  • Everything's Louder With Bagpipes: She's decent with them.
  • Fiery Redhead: Energetic and outgoing, as opposed to her family's reclusive lifestyle.
  • Funetik Aksent: Her bio, substituting "tae" for to and "nae" for not and no.
  • Long Neck: Hers is slightly sloped forward and extended, due to her heritage.
  • Mistaken for Romance: She and Gil, who are both freshwater monsters, by Lagoona and Sirena. It turns out that Gil was just helping her figure out how to tell her parents about her seawater boyfriend Finn... who shortly breaks up with her.
  • Multicolored Hair: Only on the doll, where the top ponytail is a natural red and the rest is a creamy orange tone.
  • Mythology Gag: Lorna loves to photobomb, in contrast to her clan being extremely photo-shy. She can even be seen in some the selfies in Amanita's packaging!
  • Nice Hat: Her doll's tam, emblazoned with her family plaid.
  • Quirky Curls: Curly hair, and the top section is pulled into a ponytail with much larger curls.
  • Saying Sound Effects Out Loud: "Photobomb!"
  • Stock Ness Monster: Her family. Her diary heavily implies her grandma was the original one that appeared in the famous picture.
  • Super Speed: This is what aids her in her photobombing, where she only appears in the picture- she's nowhere to be seen before the picture is taken, and she's gone before you can even look at it.
  • Symbol Motif Clothing: Celtic knots feature in her dress and earring, and her body is covered with molded knot detailing. Her skirt has a Nessie pattern.
  • Unusual Ears: Fins, as is the trend for water monsters, which are flared and angular.

I'm all about big hair, big shoes, and BIG attitude!
A maricoxi from Monster Picchu who is an exchange student at Monster High and Abbey's second cousin. She's loud, bold, and proud.
  • Amazing Technicolor Population: The final doll is greyish brown with a slight purple tone, but her prototype was bright pink.
  • Bait and Switch: In "Agony of D'Feet", she says she used to be insecure about her foot size...because she thought they were too small.
  • Beware the Nice Ones: She gets very angry when the ghouls are complaining about their appearances after trying on their Gloom and Bloom outfits, as she's a firm believer in loving oneself and accepting your flaws.
  • Bigfoot, Sasquatch and Yeti: The maricoxi is a South American example of the bigfoot cryptid legend, and making her Abbey's cousin fits the dichotomy. To fit the part, she's on the big-sister body, she has very furry limbs, and her feet are the biggest of any Monster High character save for Gooliope.
  • '80s Hair: Which she can lose guinea pigs in.
    Marisol: Hey! Where's Piggy Pantalones?
    *said pig pops out of pink mass of hair*
  • Genki Girl: Mari is energetic, athletic, and extremely vivacious. In "Meet You in Monster Picchu", Abbey follows her cousin about the length and breadth of Monster Picchu before Mari finally gets on the train to Monster High.
  • Gratuitous Spanish: She is South American (Peruvian), so it's justified.
  • Hairy Girl: Prominent leg and forearm hair, as is the form for sasquatches.
  • Huge Schoolgirl: Since her doll uses the "Big Sister" mold, she's canonically even bigger than Abbey.
  • Multicolored Hair: Shades of raspberry pink, with lime green sections in the front styled into braids.
  • Nice Hat: A small green one mounted on a headband.
  • Symbol Motif Clothing: Footprints, which appear on her bolero jacket, skirt, and bag.

     Kjersti Trollsøn
Ha! I win, again.

Hailing from Goreway, the videogame-loving daughter of trolls.
  • Adorkable: Totally.
  • All Trolls Are Different: She and her brothers have Norwegian accents and live in this world's version of Norway, as a nod to trolls' Scandinavian origins. However, her brothers are big, muscular and have grey skin while she's small, slight and has light pink skin.
  • Amazing Technicolor Population: Light pink skin.
  • Ambiguous Disorder: Her tendency towards isolation, uncanny proficiency in mechanics, predisposition towards logic and overly complicated writing manner bring to mind something on the autism spectrum.
  • Exotic Eye Designs: Her pupil, iris, and eyelights are pixellated.
  • Friendly Rivalry: With Ghoulia. Each respects the others' skill.
  • Gadgeteer Genius: She was able to decipher how to open an ancient box without damaging it at three. Looking at devices, things just click in her head. She's confused that people think her skill bizarre.
  • Gamer Chick: Her brothers may be better than her at various troll sports, but none of them can beat her in a video game. She comes to Monster High to challenge Ghoulia Yelps, the only other monster with a higher score than her in a videogame leaderboard. She even writes the word noob in her diary.
  • Girlish Pigtails: Ja.
  • Homeschooled Kids: She was homeschooled along with her brothers before she came to Monster High.
  • Meaningful Name: Her last name is traditionally Scandinavian, where the name would be "[X]'s son". Since Kjersti is a troll's daughter, her last name is Trollssøn.
  • Multicolored Hair: Hot pink and klein blue.
  • My Greatest Failure: Losing a videogame battle to Ghoulia Yelps due to a split-second finger slip. She'd repeatedly reviewed the footage and stressed over it for the longest time— and when Ghoulia beat her in a Dead Fast game, it was the last straw for her to come to Monster High to regain her title.
  • My Greatest Second Chance: Coming to Monster High for a rematch with Ghoulia Yelps. The initial conflict has Kjersti and Ghoulia staring each other down ominously, complete with Eyed Screen and a tumbleweed. They're then using their handheld consoles so frenetically they both explode and give the ghouls a major case of Ash Face. They realize they're well matched, laugh it off, and are seen later as gaming pals.
  • Nice Hat: A knitted blue cap with horns, made to emulate a battle helmet.
  • Odd Name Out: Of her three older brothers: Stomp, Grunt, and Clobber.
  • Outnumbered Sibling: She's the youngest of four siblings, and the only girl.
  • Pointy Ears
  • Quirky Curls: A Gorewegian gaming kid prodigy, with very curly hair.
  • Samus Is a Girl: Her screenname is gender-neutral and she (understandably) doesn't like or use voice chat, so after months of speaking to her online Heath thought she was a manster. That's also why he didn't tell her the person who'd beaten her in a climactic game was Ghoulia— he thought Kjersti would have been ashamed.
  • The Runt at the End: Introduced right after her three significantly larger bros.
  • The Spock: Thinks everything through absolutely thoroughly.
  • Tuckerization: Named after Kjersti Johnson, a high school student with cerebral palsy who pointed out that Share-A-Smile Becky (a 1997 wheelchair-using doll) would not fit into the elevator of Barbie’s $100 Dream House. Mattel later announced that future models of the house would be designed to fit Becky.
  • Spock Speak: Her diary is full of this.
  • Stealth Pun: She's a gaming troll.
  • You Gotta Have Blue Hair: This is half of her hair's colors.
  • Youngest Child Wins: Wins at videogames every time, that is.

     Batsy Claro
Not in MY jungle!
Voiced By: Cristina Milizia
Hailing from Costa Shrieka, Batsy is the daughter of the white vampire bat. She lives in the forest with her family and gives tours to groups of monsters who visit it, but doesn't think highly of them as they often disrespect the environment.
  • Amazing Technicolor Population: A pearlescent pinkish white.
  • Animal Motifs: Angular white bat shaped decorations adorn her clothing.
  • Brown Eyes
  • Cute Little Fangs
  • Facial Markings: Green and white patterns, and a pink bat on her forehead.
  • Long Distance Relationship: In her diary, we see that entering in the Monster Exchange program forces her to enter into one with an unnamed boyfriend... that she was actually trying to break up with when she talked to him.
  • Make Me Wanna Shout: Her echolocation allows her to project her voice, and we see her destroy a harvester in "From Fear To There Part 1".
  • Multicolored Hair: White with green streaks.
  • Mythology Gag: States her favorite food as "blood... oranges".
  • Nature Hero: If you're around her and mess with the environment, you do so at your own peril. After she's selected for the exchange program, she turns against Monster High after seeing an endangered Ghost Orchid being taken there— and decides to go only to put the plant back where it belongs. When she arrives she finds the plant in the MH greenhouse with Venus McFlytrap and prepares to forcibly retrieve it. When Venus reveals she's actually creating a new type of plant food to help the Orchid's pollination, however, Batsy has a change of heart.
    Batsy: That Ghost Orchid is staying here at Monster High— and, so am I!
  • Not Good with People: A mild example of Type 2. She feels a lot more attuned to the forest than with others, but respects those who respect the environment. This leads to her friendship with Venus.
  • Our Vampires Are Different: Most likely based on the hupia, a bat-like spirit with a penchant for fruit, and partially based on the real-life white vampire bat. She'd probably be better described as a werebat, as her traits are more batlike than vampiric, having echolocation, wings, a fruit diet, and acute hearing.
  • Pointy Ears: Sharper than the other vampires' and hypersensitive to sound.
  • Symbol Motif Clothing: White bats and woven grass patterns.
  • Winged Humanoid: Large tribal-carving styled ones in the same color as her skin.

     Isi Dawndancer
I belong here because everyone accepts me, and the way I express myself.
The Native Scaremerican daughter of a deer spirit. She's flirtatious, and loves dancing so much that sometimes all it takes is music to get her going.


     Deuce Gorgon
Voiced By: Yuri Lowenthal (Season 1-2), Cam Clarke (Season 3), Evan Smith (Season 4-present)
Son of Medusa, and co-captain of the casketball team with Clawd Wolf. In a sometimes tumultuous but still strong relationship with Cleo De Nile, and they occupy the spot of the school's premier power couple.
  • Blessed with Suck: Take a guess. Nowadays, he is able to control it so it wears off after 24 hours. When he was a kid he accidentally stoned his pet dragon, Smokey. The effects are supposed to wear off on the event's anniversary, but Deuce doesn't know which one.
  • Breakup Song: "Sorry It's Over" in Boo York, Boo York, after Nefera goads him into breaking up with Cleo.
  • Cool Shades: He wears them at all times so he doesn't accidentally turn anyone into stone. For his dance outfit in Welcome to Monster High, his masquerade mask takes the form of these.
  • Coordinated Clothes: Not overt, but his Boo York, Boo York release reflects Cleo's outfit with an Egyptian collar print on his shirt.
  • Curtains Match the Window: He has green, serpentine pupils.
  • Cute Little Fangs: Welcome to Monster High gives him these.
  • "Freaky Friday" Flip: At the end of "Freaky Fridate" after a kiss from Ghoulia-as-Cleo swaps him with Slo Mo.
  • Gorgeous Gorgon: A male example.
  • Hidden Depths: He's more sensitive than he initially seems.
  • I Want My Beloved to Be Happy: In Boo York, Boo York, he's coaxed into breaking up with Cleo by Nefera to ensure the creation of the De Nile-Ptolemy Dynasty, wrongly thinking this will make Cleo happy. They're back together by the end of the movie.
  • Mistaken for Cheating: Cleo thinks he's cheating with Operetta when she sees both of them leaving the catacombs. When it's proven this is not the case, Cleo insults Operetta anyway, causing Operetta to invoke this a second time.
  • Official Couple: With Cleo.
  • Punny Name: A hip name derived from "Medusa".
  • The One Guy: Not for the franchise as a whole, and not really one of the main characters, but he was initially marketed this way.
  • Totally Radical: Played straight starting in Season 3.
    Nefera: Daddy says he's a slacker, his hair's too long, and he says dude like every other word!
  • Understanding Boyfriend: It definitely takes a saint-like patience to handle an Egyptian princess for a girlfriend, especially during said princess' less-than-mellow days.
  • Unmanly Secret: Secretly loves to cook, and pretends to hate Culinary Arts class. He even made his own Greek vegan recipe.

     Holt Hyde/Jackson Jekyll
Voiced By: Cindy Robinson
Two students, one body, each an alter-ego depending on who you ask. The 4th generation grandsons of Henry Jekyll/Edward Hyde, and transplants to Monster High after it was revealed Jackson was no normie. At first, Jackson Jekyll existed during the daytime and Holt at night, though neither, or Holt at least, seemed to know about the other. Since, they've each become aware of their condition and weren't initially too enthused. Their condition has also changed: Holt's brought out by loud music with a beat. Jackson is a timid, shy yet cute nerd, and Holt is the loud and boisterous school resident DJ.
  • Added Alliterative Appeal: Both names.
  • Adorkable: As Jackson.
  • Amazing Technicolor Population: Holt has blue skin.
  • Birds of a Feather: Holt and Operetta have a short-lived relationship. Both are associated with music, and both have markings on the left side of their faces.
  • Distressed Dudes: In Ghouls Rule!, where Holt was framed for trashing the normie school, and was sentenced to the "Trick-or-Treatment". The school pulls together to save him.
  • Early-Bird Cameo: Jackson is first mentioned in Deuce's diary and as his best friend in the official bio. He is mentioned again in Draculaura's and Clawdeen's.
  • Fantastic Racism: Jackson's first appearance in the webisodes shows us how "normies" are viewed by many monsters. Even Heath, his cousin, is a little embarrassed to admit they're related at first. Deuce quickly accepts Jackson, though, probably because they've already met
  • Fiery Redhead: As Holt, a literal hot-head.
  • Flaming Hair: As Holt.
  • Half-Human Hybrid: Their maternal Jekyll/Hyde side of the family makes Jackson human and Holt a monster, while their father gives Holt fire elementalism on top of it.
  • Hollywood Nerd: Jackson, especially to Holt, who complains about waking up in "nerdy" clothing.
  • I Just Want to Be Normal/Special: Holt experiences the former, due to his sometimes violent temper accompanied by uncontrollable flames, and Jackson feels the latter, due to being the only "normie" in an all-monster school. He even once asks Draculaura to turn him out of desperation, an offer she respectfully declines.
  • Jekyll & Hyde: Well, duh. Whenever one side is "awake", the other has a blackout. Originally, in the diaries, Jackson was awake during the day, but became Holt at night. Later chronologically in the webisodes, Jackson turned into Holt if he heard loud music with a beat. This was finally addressed in Jackson's journal, explaining that "the volatile nature of [his] elemental side + [his] Hyde heritage + being a teenager = constant change."
  • Large Ham: Holt. "Yo FRAN-KEEEEEEEYEAAH!"
  • Multicolored Hair: Black and blonde as Jackson.
  • Red Oni, Blue Oni: Jackson's the blue and Holt's the red. This is reflected by their eye colors.
  • Ship Sinking: With Frankie in the webisodes. Yes, having two constantly altering personas makes dating very, very difficult. The second was subverted, though; Frankie took a break from them so they could focus on getting along and not constantly lashing out at each other, and now they're on good terms with one another. In the Monster High app, the possibility of them making up is teased with a cute pic of Jackson and Frankie on a picnic.
  • Ship Tease: Jackson with Draculaura at first, but it didn't last. Holt with Operetta until his temper ruined a date. Both of them with Frankie later on — twice over.
  • The Reveal: During "Here Comes Treble", when Jackson is exposed to loud music, he makes a mad dash out of sight from public view. Unfortunately, he doesn't make it in time and changes mid running up the school staircase where everyone sees him.
  • Token Human: Subverted.

     Clawd Wolf
Voiced By: Yuri Lowenthal ("Fur Will Fly"), Ogie Banks (current)
Clawdeen's level headed older brother. He's the captain of the school's football and casketball squad but realistically knows he can't always be in sports, so he studies to go into sports medicine. His basic doll release was with Draculaura, and the two are strong contenders for Monster High's most stable relationship.

     Heath Burns
Voiced By: Yuri Lowenthal (Volume 1), Cam Clarke (current)
Heath Burns is a fire elemental, and thus has the ability to use flame. He was at first an extra in the webisode "Substitute Creature" and was shortly introduced as Draculaura's short-lived crush. Heath is a show-off and gets on the girls' nerves by being self-centered and insensitive. He's friends with most of the boys. In "Fear Pressure", we learn he is Jackson's cousin.

     Sloman "Slo Mo" Mortavich
Voiced By: Audu Paden
One of the zombies and Ghoulia's boyfriend. He hangs with the guys and is in the chess club, and is also one of the school's casketball co-captains.
  • Adorkable
  • "Flowers for Algernon" Syndrome: In "Flowers for Slo Mo", he initially feels too stupid for Ghoulia. Lagoona doesn't think so, but when she mentions Cleo's potions, he gives her Puppy-Dog Eyes and she agrees to take him to her. The potion makes him very intelligent, but he becomes an insufferable know-it-all, angering Ghoulia. He agrees to take the antidote when Lagoona points out the problem, and all is well.
  • "Freaky Friday" Flip: Ends up swapped with Deuce for the last bit of "Freaky Fridate" as Cleo-as-Ghoulia kisses him.
  • Frozen Face: Most of the time but when he smiles it's really cute.
  • Genius Bruiser: Unbeatable at chess even by Ghoulia, stellar in math, exemplary at spatial thinking, and able to break a guitar in half no sweat.
  • Gonk: In the webisodes, his face is always slack and his eyes are crossed. Not the case for his dolls, which are much more flattering.
  • Hair-Trigger Temper: A mild example. He does not react well to being cheered during his chess games or to Heath's guitar playing. Being poked in the eye seems to be an exception though (at least if it's Ghoulia).
  • Intelligible Unintelligible: Like Ghoulia.
  • Lovable Jock
  • Meaningful Name: It's short for "Sloman Mortavich", and also refers to the way his zombie movement makes him look as if he's living in slow motion.
  • Multicolored Hair: He gains a black streak in his blue hair for his Love's Not Dead release.
  • Oblivious to Love: Subverted in that they were already dating, but in the Love's Not Dead doll release diary he takes an awfully long time to realize Ghoulia's trying to get him to ask her to the dance... after she's taken him to clothes stores, asked him if he's ever worn a tuxedo, and generally dropped more hints than the little lost kids in the woods dropped breadcrumbs.
    Slo-Mo: Well, how was I supposed to know that Ghoulia wanted to go to the prom? She has never even talked about it. In fact, the only thing she has even wanted to talk about lately are the new dresses and shoes she has been looking at, which I find very odd since she rarely ever mentions things like this and... oh no. I am in serious trouble.
  • Official Couple: With Ghoulia. And he is easily willing to fight someone over her.
  • Only Known by Their Nickname
  • Our Zombies Are Different: He's on the Varsity Chess team, as well as the Varsity Basketball team.
  • Suddenly Voiced: In "Flowers for Slo Mo", Cleo's potion doesn't only boost his intelligence, but it gives him articulate speech and better motor skills.
  • You Gotta Have Blue Hair

     Gillington "Gil" Webber
Voiced By: Yuri Lowenthal ("Blue Lagoona"), Evan Smith (current)
Son of the River Monsters. Has a loving but troubled relationship with Lagoona, thanks to his parents' prejudice against saltwater sea monsters.

     Manny Taur
Voiced By: Audu Paden
The son of the Minotaur, and ex-school bull-y.

     HooDude Voodoo
Voiced By: Cam Clarke
A raggedy doll created by Frankie to be her boyfriend in the webisode "HooDoo You Like?". After Frankie decides that she doesn't need a guy to fit in, she tosses him away, only for him to reveal that he's alive and heartbroken at her "breaking up with him." He gets over it later, and now infrequently tags along with the ghouls on their adventures. He was released in a 2 pack with Scarah Screams as the SDCC 2012 dolls.
  • Cute Clumsy Guy
  • The Ingenue: Arguably a rare male example, being extremely naive and innocent about most things.
  • Large Ham: He's rather... melodramatic about Frankie "dumping" him.
    • And just about any other emotion he may be feeling. He actually lists his oversensitivity and tendency to wear his heart on his sleeve as his Freaky Flaws in his later-released bio.
  • Mismatched Eyes: His button eyes are blue on one side and pink on the other. This is a Shared Unusual Trait with Frankie.
  • Nice Guy
  • The Not-Love Interest: He slowly gets over Frankie while forming a strong bond with Scarah Screams the banshee. Peers have asked them why they aren't dating, and he admits that, while he's really close to her, he just doesn't feel any romantic attraction to her.
  • Painting the Medium: His physical doll is plush, rather than articulated plastic.
  • Scary Stitches: Due to being a voodoo doll and being created by a stitched-up monster.
  • Voodoo Doll: Negative things that happen to him stretch to the other Monster High students.
  • You Gotta Have Blue Hair
  • Younger Than They Look: Like his creator.

     Invisi Billy
Voiced By: Evan Smith
Son of The Invisible Man. He has a passion for illusions and special effects, but, despite the potential for pranks, he's not a bad guy.
  • Amazing Technicolor Population: Pale bluish-white skin that fades into translucent turquoise. His body below the neck is translucent blue in his second doll release.
  • April Fools' Day: Mattel released the profile information for Invisi Billy as a teaser for his soon-to-be-released doll... on April 1st. Complete with a full package mock-up of an empty box, with the box quote, "How do you know I'm not in the box?"
  • Big Ol' Eyebrows
  • Canon Immigrant: Kinda. First seen in the Lisi Harrison series, and made a speaking debut in the webisode "Fright Dance".
  • Deadpan Snarker
  • Hipster: This is how he describes his style, which is the "alternative" variety.
  • Invisibility: Natch.
  • Multicolored Hair: Blue and black.
  • Nice Guy: Generally unassuming in the webisodes, and helps Rochelle out during her dance audition out of the kindness of his heart.
  • The Prankster
  • Official Couple: With Scarah, as of "Scarah-voyant".
  • Shout-Out: Instead of a pet like most of the other characters, he owns a box which may or may not contain a cat. Officially, he owned a dog once but had to give it away since (due to his invisibility) animal control thought it was a stray every time he went out for a walk with it.
  • The Smart Guy: Adores physics, and even uses his knowledge for some of his pranks.
  • Symbol Motif Clothing: He tends to wear dual-chromatic patterns that blend together like optical illusions.
  • Toyless Toyline Character: Both played straight (see April Fools' Day above) and as of 2014, averted.

     Finnegan Wake
The son of merfolk introduced in "Ready, Wheeling, and Able", and released as a doll after winning a 2014 poll.
  • Amazing Technicolor Population: Blue.
  • Big Brother Mentor: To River (not Styxx), a young sea monster at a children's hospital who also has a motor disability.
  • Curtains Match the Window: If you count fins as hair. Both his eyes and head fin are blue.
  • Disabled Means Helpless: The ghouls initially think this of him, but it's fiercely averted: he's more than capable of getting around on his own.
  • Exotic Eye Designs: His doll has a wall-eyed look, with eye reflections pointing in opposite directions. This is to reflect the way fish's eyes are set on opposite sides of the head.
  • Handicapped Badass: Due to extensive training, he's now an extreme daredevil.
  • Our Mermaids Are Different: He's a paraplegic; his tail just "never started working".
  • Stealth Mentor: How Finnegan first interacted with River: when he was refusing to do his physical therapy, Finnegan stepped in to motivate him. After that talk, River starts his therapy and after six months is ready to return home. The last entry in Finnegan's diary is about him giving River a going-home present made with the help of Wydowna and Ghoulia— a set of waterproof temporary tattoos just like his.
    I rolled past his room and stopped just outside the doorway. He ignored me at first, so I pulled out my iCoffin and started playing a game, After a while, I could feel him looking at me, and he finally asked, "What game is that?" I told him it was Dead Fast 3. "I beat Dead Fast 2 before I got sick." I kind of grunted at him and kept playing. "Are those real tattoos?" I told him they were. "Did they hurt?" I told him they did. "Mom and Dad said I can't get a tattoo, not even for my birthday." I said, "Getting inked is a big decision. Maybe they don't think you're responsible enough to make it yet." "That's what my parents said, but I'm almost 10 and I'm way responsible." I asked him why they thought he wasn't responsible. He didn't say anything for a bit, and finally mumbled, "Cause of physical therapy." I said, "Yeah well, good luck with that. Catch you later."
  • Wheelchair Antics: His forte. Once got caught doing jumps in the empty school pool off the construction ramp by Bloodgood, and when she congratulated him he thought he'd be doing that all day— turns out she meant "While I admire your adventurous nature and athletic ability, ignoring the 'No Entry - Construction Zone' signs has earned you two hours in detention where you shall write I WILL NOT DO STUNTS IN A CONSTRUCTION ZONE a thousand times." Ouch.

Other (Faculty, Parents, etc.)

     Headless Headmistress Nora Bloodgood
Voiced By: Laura Bailey
The Headmistress of Monster High, who tries to balance doing what's best for the school, and encouraging her students to be themselves. She is often seen in the company of her horse Nightmare. Bloodgood and Nightmare had a doll release in late Spring, 2013.
  • A Dog Named "Dog": As her figure's story reveals, turns out Nightmare's species are all called Nightmares.
  • Badass Longcoat
  • Badass Teacher
  • Cool Horse: Nightmare, despite being scary-looking at first, falls into this.
  • Headless Horseman: The obvious inspiration.
  • Losing Your Head: Regularly removes her head and puts it back on.
  • Multicolored Hair: Black and violet.
  • No Name Given: Until Hexiciah's SDCC diary, no first name was given for her.
  • Not So Stoic: Mainly firm and unshakable, she can sometimes crack up. In a more serious example the story with her figure goes a little into her character as a teenager and her ordeals with finding Nightmare, showing a less self-assured Bloodgood than the one we know. She's also implied to have had a past relationship with Hexiciah before opening Monster High. She also shows distress with the Board of Deaducation's deadline on the Freak du Chic fundraising.
  • Reasonable Authority Figure: Despite being strict when it comes to the rules of the school, she encourages her students to take chances and be themselves, sometimes even directly involving herself in their actions/antics.
  • Taken for Granite: In Fright On. Gets better, though.
  • Tuckerization: Her last name references Erin Bloodgood, who's been the marketing manager for numerous Mattel franchises, including Monster High.

     Hexiciah Steam 
Voiced By: Dave B. Mitchell
The self-made cyborg scientist who built Robecca, who he sees as his daughter. Long disappeared on an expedition, he was finally found by Robecca along with his fellow explorers... and Cleo's mother.

     Mr. Rotter 
Voiced By: Yuri Lowenthal (Idol Threat), Cam Clarke (current)
A phantom who teaches at Monster High. He is known for his impossible standards.

     Mr. Hackington 
Voiced By: Audu Paden
A Cockney Igor/butcher who teaches at Monster High.

     Mrs. Kindergrubber 
A witch who teaches Home Ick.
  • Meaningful Name: She's based on the witch from Hansel and Gretel, who planned to eat the titular children—thus, her name means Childsearcher. Can't eat kids if you can't find them! It also relates to her taking in kids who don't have a home, and invokes "grub", which fits her theme.
  • Parental Substitute: She took in Robecca and Hoodude because they needed a home.
  • Perfectionist: She wants her students to follow instructions to the letter, overlapping with Germanic Efficiency.

Customization Dolls

A line of dolls with interchangeable parts allowing the owner to customize the dolls and create their own monster. Originally, parts for only one complete monster were included in each two-character pack, but later waves included the parts for two full dolls...but only one pair of shoes. Single-monster add-on packs were also sold with all of the parts but the body and upper limbs.

     Inner Monster 
A line of customizable dolls based on emotions. Each doll has accessories to create at least two different emotional looks (The deluxe pack has three) and translucent body shells that can be removed to allow you to place emotion charms on the skeleton. Each of the three smaller dolls has an expansion pack, providing an additional outfit, faceplate, and a molded wig to supplement one of their emotions.

  • Added Alliterative Appeal: The emotional personas of the dolls: Shockingly Shy and Scared Silly, Spooky Sweet and Frightully Fierce, Hauntingly Happy, Eek Excited, and Shivering Sad, and lastly, Fearfully Feisty and...Fangtastic Love.
  • Amazing Technicolor Population: Feisty/Love is light pink, Shy/Silly is gradient orange, Sweet/Fierce is light minty blue, and Happy/Excited/Sad is very pale purple.
  • Anthropomorphic Food: Spooky Sweet's expansion turns her into a candy monster, with ice-cream hair, sprinkle makeup, and a candy oufit.
  • Body Horror: Each doll has an exposed brain and translucent skin. Fangtastic Love's spider accessory takes the cake, looking vaguely parasitic and skeletal, yet disturbingly organic.
  • The Cameo: They serve as the avatars in the in-universe Inner Monster app, which helps the students get in touch with their feelings.
  • Draconic Humanoid: Frightfully Fierce's look.
  • Exotic Eye Designs: Each doll has three eye options with different designs, although Spooky Sweet and the deluxe doll's eyes are more tame.
  • Everything's Squishier with Cephalopods: Scared Silly's motif is tentacles.
  • Eyes Never Lie: All of the dolls have three eye options to reflect their mood.
  • Flaming Hair: The expansion for Fearfully Feisty has this.
  • Fog Feet: Eek Excited looks like a genie made out of a tornado.
  • Hellish Pupils: Feisty/Love has these for her flaming eyes and her "normal" blue eyes.
  • Hot Wings: Fearfully Feisty's prominent accessory.
  • Humanoid Abomination: They can look normal, but definitely qualify due to their exposed brains, translucent bodies filled with organ-like emotions, bizarre eye options, and unnatural back accessories, all of which change according to their mood.
  • Literal-Minded: The Spooky Sweet and Scared Silly mood packs, which put emphasis on "sweet" and silly" by giving the former a candy-themed outfit, and the latter a clown theme.
  • Odango Hair: The expansion pack for Scared Silly gives her a green wig in this style.
  • Peacock Girl: Spooky Sweet's default outfit.
  • Personality Powers/Psychoactive Powers: Assuming each is supposed to be just one character, the Inner Monsters have wildly different appearances depending on the mood they're experiencing, and most of them seem to imply different abilities, like fire, wind, flight, or plant control.
  • Pretty Butterflies: Hauntingly Happy has bright yellow butterfly wings.
  • Shy Blue-Haired Girl: Shy/Silly has purple hair.
  • Visual Pun: One of Spooky Sweet's emotion charms is a tooth adorned with a candy-shaped bow, i.e., a literal sweet tooth.
