List of Monster High characters
Monster High, a fashion doll and media franchise created by Garrett Sander and released by American toy company Mattel on June 11, 2010, features a variety of fictional characters, many of whom are students at the titular high school. The female characters are classified as Ghouls and the male characters are classified as Mansters. The characters are generally the sons and daughters, or related to monsters that have been popularized in fiction. The now-defunct official website identified six of the characters as Original Ghouls. In addition to the listed Ghouls and Mansters, there are other characters who have been introduced in the franchise's related media including the web/video and book series. In 2016, Natali Germanotta, sister of singer Lady Gaga, designed Zomby Gaga for the franchise as a partnership with the Born This Way Foundation. Main characters

Six of the Monster High characters have been classified as Original Ghouls according to the official website. Frankie Stein
Frankie Stein (voiced by Kate Higgins from 2010 to 2015 and Cassandra Lee Morris thereafter, iris menas in the 2022 TV series, portrayed by Ceci Balagot in the live-action films) is the daughter of Frankenstein's monster and his bride. She was born in Bavaria, Germany and the story opens with her starting school at Monster High upon turning 15 days old, making her the youngest student there. Frankie is known for her generosity, optimism, and kindness, believing strongly that everyone's flaws make them unique; but also for her naivety and innocence. Being a Frankenstein's monster herself, Frankie has light green skin and her limbs are stitched together, making them capable of functioning independently even after being detached. While this is useful, her limbs can fly off suddenly when she is tense, scared, or angry as well. To function, she is powered by electricity and has to be recharged every night via two bolts at her neck, allowing her to manipulate electricity in self-defense or to power electronics in a pinch. One of Frankie's most distinguishing characteristics is her heterochromia: her right eye is blue, whilst her left eye is green. She also has white hair with black lightning-bolt-like streaks and her fringe is pulled back and clipped. On school days she typically wears a school uniform coupled with a tie, gingham pattern, and monochrome platforms. Her love interest is Neighthan Rot. In the 2022 reboot, Frankie is the child of mad scientists Dr. and Dr. Stein, created using "the best and brightest minds in monster history". Unlike previous iterations, Frankie is non-binary and uses they/them pronouns. Frankie also has a default cybernetic left leg and several customizable prosthetics that they use in the TV series. This iteration of Frankie also has blue skin instead of green and lacks neck bolts, as this reboot is not produced in partnership with Universal Pictures, who owns the rights to the Frankenstein's monster design. Draculaura
Draculaura (voiced by Debi Derryberry in most projects, Courtney Lin in the 2022 TV series, portrayed by Naya Damasen in the live-action films) is the Romanian daughter of Dracula. Despite being a vampire, she is a vegan who consumes fruits, vegetables, and "a lot of iron supplements" instead of blood, fainting at the mere sight or mention of it. Mattel vice-president of design, Kiyomi Haverly, commented on her, saying, "She's a vegan. She's turned off by meat. Girls could really relate to that because that's part of what they're thinking of these days." Initially 1,599 years old, but turns 1,600 in the webisode "Party Planners" and in the 2012 film special, Why Do Ghouls Fall In Love, with Mattel releasing a doll line based around her birthday. In Frights, Camera, Action, Draculaura unlocks her vampire powers and earns the ability to transform into a bat. Cheerful, bubbly, and excitable, Draculaura is one of the friendliest and most popular ghouls in Monster High. She currently dates Clawd, Clawdeen's older brother, and has a pet bat named Count Fabulous. She primarily dresses in pink that complements her pink skin and black pink-streaked hair. On school days, she secures her hair into pigtails and wears a pink zipper top with a ruffled white collar and fishnet fabric sleeves, paired with a white miniskirt and girly pink boots. Due to her birthday being on Valentine's Day, she also has a pink heart-shaped tattoo at the corner of her left eye, and is quite romantic. In the franchise's first reboot, Draculaura originally lived with her father Dracula in a mansion on a hill overlooking "normie town", and, wanting to have friends like her, she talked her father into turning the mansion into Monster High, as seen in the first film Welcome to Monster High. She and her friends often go on adventures to find more monsters to enroll. The 2022 reboot portrays Draculaura as an accentless character with Taiwanese-American heritage (Filipino-American in the live-action movies). However, as of the episode "Creature Clash", she mentions her dad being Transylvanian. In the reboot, Draculaura faces pressure to be an excellent student like her father and relatives. She also deals with her secret passion for witchcraft, a practice strictly forbidden in the monster world due to the threat it poses to monsterkind, and is considered a "filthy human habit". Clawdeen Wolf
Clawdeen Wolf (voiced by Salli Saffioti in most projects, Gabrielle Neveah Green in the 2022 TV series, portrayed by Miia Harris in the live-action films) is the Brooklyn-accented African-American 15-year-old daughter of a werewolf. She is portrayed as a brown-skinned werewolf with chocolate brown curly hair and pierced ears. Two of her siblings, Clawd and Howleen, study alongside her at Monster High, and her older sister Clawdia has graduated and become a working adult. In school, Clawdeen is known for her impeccable sense of fashion and aspires to become a fashion designer  in Scaris. She primarily dresses in purples and yellows; on school days, she wears a leopard-print top, a leather jacket, and a purple miniskirt paired with matching stockings and grey platform boots. Being a werewolf, she possesses immense strength and speed, especially during the full moon, but this also makes her prone to bad moods and fiery tempers. Before the ghoul squad was formed, she was Draculaura's best friend and highly protective of her. She also has a purple pet kitten named Crescent. In the 2022 reboot, Clawdeen is the Afro-Latina daughter of a werewolf mother and a human father. Before learning her werewolf heritage, she spent most of her life in the human world, where she always had a fascination and interest in monsters. On her fifteenth birthday, she was gifted a necklace by her father, and with its guidance, she stumbled upon Monster High by accident. Clawdeen later discovers that her necklace is the moonclaw talisman, one of many talismans created by the Monster Council, which gives her with incredible strength, speed and the ability to transform from a werewolf to a human and vice versa at will. She aims to find her mother, who had disappeared many years ago into another dimension called Beheme; it is through her attempts that she was able to meet her long-lost brother Clawd in "Paw-zzle Pieces". In the live-action films, Clawdeen spent her life hiding in the human world and initially resolved to hide her human side at Monster High after discovering that she turns completely human when nervous or scared. Lagoona Blue
Lagoona Blue (voiced by Laura Bailey until 2015, Larissa Gallagher thereafter until 2018, Valeria Rodriquez in the 2022 TV series, portrayed by Lina Lecompte in the live-action films) is the daughter of the gill-man Wade Blue and a sea nymph. She is portrayed as a blue-skinned monster with golden curls with blue highlights. On school days, she wears a pink halter top, a blue jacket with scale patterns, and short pants and heels reminiscent of swimming gear. Like Frankie, Lagoona is known for her kindness, warmth, and friendliness which offers the ghouls much reassurance in tense moments. Due to her childhood in the Great Scarrier Reef and her heritage, she is a skilled swimmer on the Monster High swim team. Despite sharing mutual feelings with another monster, Gillington "Gil" Webber, his parents disapprove of their relationship due to her sea-monster heritage. She turned into a freshwater monster momentarily from Howleen's wish in 13 Wishes. In the 2022 reboot, Lagoona is a pink-skinned Honduran sea monster described as having grown up in a sunken Castillo with little knowledge of the outside world. Lagoona is fierce and savage, but also sweet and bubbly; she loves romance and telenovelas. Cleo de Nile
Cleo de Nile (voiced by Salli Saffioti in most projects, Kausar Mohammed in the 2022 TV series, portrayed by Jy Prishkulnik in the live-action films) is the second daughter of an Egyptian mummy named Ramses de Nile. She is Monster High's "queen bee" – the most popular girl in school – as well as the student council president and captain of the Fearleading Squad. Her boyfriend is the popular Deuce Gorgon and they share a close relationship. Being a mummy who was preserved for many years, her appearance is that of a 16-year-old girl, but she is actually over 3,000 years old. While her profile lists her as being 3,357 years old, previous iterations, as well as the videos, had shown her true age to be 5,842 years old. Cleo is portrayed as an auburn-skinned girl with black hair with gold highlights. Her top and bottoms are the residues of her Egyptian mummy bandages, which she adds style to with glittery blue stripes and bandage ribbons. Being a member of Egyptian royalty, Cleo is very proud of her heritage, which is displayed in the form of her blue rhinestone tiara and large gold earrings. As a result, she can be somewhat of a diva, priding herself greatly on her popularity, fashion sense, and the many amulets that her family pyramid houses. However, she has great leadership skills and often looks out for her friends. Cleo's catchphrase is: "Oh my Ra!" and her screams can shatter glass. In the 2022 reboot, Cleo maintains her position as the school's queen bee. She and Deuce are no longer romantically involved, with the first live-action movie specifying that her egocentric behavior led to Deuce breaking up with her. Cleo initially antagonizes Frankie and Clawdeen but has a change of heart by the film's end. In the TV series, Cleo is kinder than her live-action and Generation 1 versions, but she still has a desire to be number one. Ghoulia Yelps
Ghoulia Yelps (vocal effects by Audu Paden in most projects, voiced by Felicia Day in the 2022 TV series, portrayed by Lilah Fitzgerald in the live-action films) is the bespectacled daughter of a zombie couple from Canada. She is Cleo's personal assistant and best friend. The smartest ghoul at Monster High, her personality is that of a shy and bookish girl with a sense of mischief. Due to being a zombie, she can only speak in moans and groans – a physical limitation that all zombies have. She is also the shortest girl at Monster High, but this may be due to the fact that she can never stand up straight. Ghoulia has a romantic interest in Slo-Moe, a tall male zombie on the chess team. In her free time, she is a hardcore fan of an in-universe comic book series titled "Dead Fast", and enjoys dodgeball. Her favorite color is red and she has a pet baby blue owl named Sir Hoots-a-Lot. In the 2022 reboot, Ghoulia no longer limps and can speak English. She is the best gamer at Monster High as well as a skilled skateboarder. Although introduced as one of the six Original Ghouls, she was no longer listed among them following the 2016 film special, Welcome to Monster High. Ghouls

In the 2022 reboot, she is Indian-American. The TV series specifies that she's from Nepal, as she and her mother speak Nepalese.

Graeme Ambrose, of Loch Ness Bid organization praised the concept: "The monster is shrouded in mystery and perhaps slightly scary in a nice way for children and it is therefore of little surprise that Mattel have chosen to introduce this character, daughter of the Loch Ness Monster. ...

Toralei's mother Catarina Stripe is the current leader of the werebeasts, taking the crown after Clawdeen's mother, the former wereleader, got stuck in Beheme.

According to "Bat Dialing Disaster", he has already had his birthday, which must officially make him eighteen years old. He is the oldest child still living in his parents' house. He dated Cleo prior to Frankie attending Monster High in the dolls' diaries when he was struck by one of C.A. Cupid's arrows. Eventually, the magic wore off and he broke up with Cleo who began dating Deuce the next day. Clawd is the Big Monster on Campus and plays on the casketball team with Deuce. He owns a pet gargoyle bulldog named Rockseena. He is also overprotective of his sisters Clawdeen and Howleen according to "Fright On!". Despite being long-time friends since younger youth, he finally falls for Draculaura in Volume 2 and she did likewise, but originally. Clawd has dark brown fur and bright yellow eyes. In the 2022 reboot, Clawd is Clawdeen's long-lost brother. He was born while his mother was trapped in Beheme where time flows differently, resulting in him being older than Clawdeen. Like Clawdeen, Clawd is also now Afro-Latino, and can speak English and Spanish interchangeably. Deuce Gorgon
Deuce Gorgon (voiced by Yuri Lowenthal in the first two volumes of the web series, Cam Clarke for the first half of Volume 3, Evan Smith for the other half and continuing to Volumes 4 and 5, Tony Revolori in the 2022 TV series, portrayed by Case Walker in the live-action films) is the son of the gorgon Medusa. Like his mother, he has snakes for hair, which he styles in a "snake-hawk". He is 16 years old and hopes to get his driver's license soon. He is a member of the casketball team. He also loves to cook and is quite a skilled chef, but he is too self-conscious to showcase his culinary ability to anyone. Deuce inherited his mother's ability to turn people into stone, though he has been able to control the effect so that it lasts for only about twenty-four hours. His petrifying stare does not work on gargoyles which he learns by bumping into Rochelle Goyle. He takes off his sunglasses only when he talks to her. In "Hiss-teria", he reveals that he accidentally petrified his first pet (a dragon named Smokey) when he was a young boy and the effect has lingered to the present day. Deuce is dating Cleo, who seems to always find new ways for him to spend all his money on her. Despite that, Deuce genuinely loves Cleo and wrote a song to express his feelings for her. His pet is a two-tailed rat which he named Perseus after Perseus who Medusa clashed with in her past. Understandably, Medusa is not amused. His favorite color is neon green, which neon green is the color of his hair and Neon Green eyes. His favorite food is "Greek Fusion" (his own creation). Deuce's first name is clearly, obviously named after part of Medusa's name by Sander, the "dus" part, such as "Meh-DEUCE-uh". In the 2022 reboot, he now has two moms, Medusa and Lyra, with Medusa having very high expectations for him to succeed in school. He wears a hat to hide the snakes on his head, each of which can now speak and embody the seven sins. Unlike his previous incarnations, this version of Deuce is not in a romantic relationship with Cleo de Nile, as they broke up deciding they are better as friends. In the live-action films, Deuce breaks up with Cleo due to her egocentric behavior and is Clawdeen Wolf's love interest. Finnegan Wake
Finnegan Wake (voiced by Cole Massie in the TV series) is a merman who is the son of a mermaid. He is shown to be wheelchair bound on land which leads the ghouls to underestimate his abilities. Finnegan is shown to be a daredevil and thrill seeker who doesn't let his disability get in the way of what he wants to do. He was originally referred to as Rider in the webisode, which may be a nickname. He was originally called "Ryder" or "Rider". He was brought back for the 2022 reboot. Finnegan is a guitarist. Garrott DuRoque
Garrott DuRoque (voiced by Evan Smith) is a French gargoyle from Scaris, France and son of a Gargoyle who is Rochelle Goyle's boyfriend. He now comes in a doll two-pack with Rochelle. His flowers are his "pets" and he is a perfectionist. Gillington "Gil" Webber

He was first introduced in the webisode "Blue Lagoona" and has made recurring appearances since. Gil is one of the top members on the swim team alongside Lagoona. When on land, Gil has to wear a water-filled helmet over his head in order to breathe, though "Hatch Me if You Can" and the Gloom Beach arc shows that he can be on land for a short period of time without it. Gil is from freshwater, which is why it is hard for him and Lagoona (who can survive in saltwater) to be together. In the 2022 reboot, Gil was accepted into Monster High later in the school year, and is Lagoona's love at first sight. Throughout the episode "A Little Boost", Lagoona tries to do all she can to get Gil's attention, but by following Frankie's advice about being herself, she was able to bond with him by the end. Heath Burns
Heath Burns (voiced by Yuri Lowenthal in the first volume of the web series, Cam Clarke from the 2nd volume onwards, Alexander Polinsky in the 2022 TV series, portrayed by Justin Derickson in the live-action films) is the teenage son of two Fire Elementals. In the Polish-dubbed webseries, his name is Ross Burla, and in the French dub, he is named Thomas Cramé. Heath was first seen as a background character in the episode "Substitute Creature". In the episode, "The Hot Boy", he was shown to be Draculaura's short-lived crush. In "Fear Pressure", he mentions that Jackson is his human cousin, a possible reference to when many fans confused Heath Burns for Holt Hyde. Heath's first mention in the dolls' continuity is in Abbey's diary where he is constantly hitting on her with corny one-liners. Heath primarily serves as the comic relief, being the butt of many physical jokes and the class clown. He and Abbey are now dating. He thinks she's "hot" and she likes that he "makes her laugh". He often calls Abbey "baby" which she corrects him over constantly, telling him her name is Abbey not Baby. In the first novel, Heath appears to be a normie (human). In Book 2, "The Ghoul Next Door", this Heath is revealed to be a RAD (monster) when he sneezes fire. He explains that his ability appeared when he turned fifteen. Starting out as gassy outbursts, Heath's ability is still dangerous. Heath has yellow skin, red eyes and orange hair that bursts into flame when he's excited. He's shown as being close friends with Manny Taur, and the two are often seen hanging out together. In the 2022 reboot, he is now the son of the fire elemental Hades Burns and an unnamed female fire elemental. He is very motivative to his friends and is a passionate enviornmentalist. Invisi Billy
Invisi Billy (voiced by Evan Smith) is the son of the Invisible Man. Invisi Billy can be seen as a bit of a prankster, but he can be kind and sweet, as in helping Rochelle Goyle with her dance in "Fright Dance". He loves drama, particularly special effects which are his forte. His girlfriend is Scarah Screams (who is also his BFF) as they got together in the webisode "Scarah-Voyant" thanks to Frankie. Catty Noir is also Invisi Billy's BFF. Invisi Billy first appeared as an April Fool's joke on Facebook, picturing an empty box with the blurb "How do you know I'm not in the box?" Since then, his character and design have been refined and changed. His doll has very pale blue/grey skin that fades to transparent blue are his feet. He has dark blue hair and grey eyes. His ears are both gauged, making him the first Monster High boy to have both ears pierced. Jackson Jekyll / Holt Hyde

Jackson Jekyll (voiced by Cindy Robinson) is a normie boy at Monster High, and enjoys sports (particularly casketball) and video games. Jackson is the son of "Dr. Jekyll", though it's unclear if this is his father, though in the books, Dr. Jekyll is his mother, Sydney Jekyll. His diary implies the original Dr. Jekyll and Mr. Hyde were his grandfather and his mother seems to possess the ability to shift. In the web series, Jackson is related to Heath Burns (they are cousins) but through which parent hasn't been clearly explained. Jackson is depicted as a major nerd in the webisodes and specials, though he seems to possess a wicked sense of humor ("Oh I fit in...  my locker, trash cans... you'd be surprised what those guys fit me into"). He is first mentioned in Draculaura's diary where he unsettles her father by telling him he needs to "drive a stake into something". Jackson has black hair with blond or yellow streaks. His eyes are blue. He wears glasses, has one eyebrow pierced and has a Yin Yang symbol tattooed between his shoulder-blades. Holt Hyde (also voiced by Cindy Robinson) is the alter-ego version of Jackson Jekyll and the son of Mr. and Mrs. Hyde, who Jackson turns into when loud music plays (when he sweats in the Lisi Harrison novels). Originally in the diaries, it was the sun setting that triggered Jackson's transformation into his alter ego. His diary explains that the trigger is likely to change several times as he ages before finally settling. Holt on the other hand seems to be more fire elemental than normie. His skin is bright blue, his eyes are red and he has fiery-colored hair. He's depicted in the webisodes and specials as rather excitable and loud. He loves to DJ and is friends with Operetta. They tried to date once, but Holt's hot temper spoiled things. In the prom website event called "A Night in Scare-adise" on Monsterhigh.com he and Operetta attended prom together. Operetta was quoted as saying he "rocks my l'il ol' face off." Holt is often shown as a DJ at school dance events. He annotated Jackson's diary with sarcastic remarks. Like Jackson, Holt has a Yin Yang tattoo on his back and a pierced eyebrow. (His Swim Class doll is missing this detail however). In the books, his name is DJ Hyde. Jackson and Holt share a pet Chameleon named Crossfade. Manny Taur
Manny Taur (voiced by Audu Paden in most projects, Jordan Coleman in the 2022 TV series) is the son of the Minotaur. He is a half-bull half-human in appearance; he has blonde hair, a ring on his nose and wears a red shirt with a labyrinth printed on it, along with jeans pants and brown shoes. Manny initially debuted as a school bully in Monster High, usually picking on Jackson Jekyll, as shown in "Miss Infearmation". He also had a dislike for zombies, due to them being slow. In "Manny Taur's SDCCI diary", it is revealed Manny himself was bullied in middle school. After an encounter with Abbey, he changed his ways; although he stopped bullying people, he can be still gruff to others. His personality change helped him get into a relationship with Iris Clops. In the 2022 reboot, Manny is a calm and gentle monster and he loves to read and is great at solving puzzles. His smarts rival that of Draculaura's who often competes with him to become top student. Neighthan Rot
Neighthan Rot (voiced by Josey Montana McCoy) is one of the new "hybrid" students of Monster High. He is the son of a zombie (father) and a unicorn (mother). He has long black hair with blue, yellow, and red highlights in a ponytail, and he wears a colorful shirt and pants whose color splash patterns seem remincient of anatomical models. Neighthan is somewhat clumsy, but he is a social monster who loves hanging out with his beast friends. He doesn't like monsters judging other monsters based on their appearances. He has the ability to heal thanks to his unicorn horn. He makes his first webisode appearance in "Graveyard Grates". He looks a little less like a unicorn because he only has a tail, a horn, and rainbow hair. From his zombie side, he has grey zombie-skin, and a marking on the left side of his face around his eye. Neighthan has human legs and feet instead of horse-like legs and hooves. He has a blue unicorn-horn, and wears a ponytail with a strand of hair coming down the left side of his face. He also wears a T-shirt with a rib cage on it and difficult multi-colors. He has romantic feelings for Frankie Stein, which seems to be mutual. Neightan was designed by Garrett Sander. Porter Geiss

In the 2022 TV series, Romulus has purple hair and is the leader of Monster High's Werewolf Council, formed by him, Barkimedes and Howleen. Romulus is a mean-spirited jerk with a rude attitude. He and Barkimedes do not like Clawdeen due to her human side and tried to trick her, but failed. In "Part of the Pack", Romulus tried to befriend Clawdeen only to get her moonclaw talisman so he could become a powerful werewolf and claim the crown as wereleader of the werebeasts, but Clawdeen discovered and, thanks to Howleen and her sudden change of heart, escaped just in time. Sloman "Slo-Mo" Mortovitch
Sloman "Slo-Mo" Mortovitch (vocal effects provided by Audu Paden) is a zombie who was originally addressed as Moe "Slow Moe" Deadovitch instead throughout the series, before any dolls were released and before it was officially addressed on Monster High's website in the description of "Flowers for Slo Moe".
