Heroine Overview

Right now I'm feeling happy, sad, confused, enlightened, worried, hopeful and hungry all at the same time. Is this normal?
~ Frankie Stein

Frankie Stein is one of the main protagonists in Monster High franchise. She is the daughter of Frankenstein and is very kind and clever.

She is voiced by Madoka Yonezawa in the Japanese version, and by Kate Higgins in the English version.

About the Character

Physical Description

Despite being only a few days old, Frankie's physical age is that of a fully-grown girl in her late teens. Also, despite being a monster made up of parts from different people, she has been created with a well-balanced, attractive body, unlike her father.

She has long white hair with black streaks, similar to her mother's hair, which may be inspired by the Bride of Frankenstein. It was originally styled with jagged streaks, and her fringe was pulled back over her head and pinned back with a hairclip but was later changed so the streaks where more straight and natural-looking, and is now styled with a side fringe that covered her forehead, again held with a clip.

She has light, mint green skin, and has a condition known as heterochromia which gives her odd-coloured eyes - one green, one blue (though likely from being assembled from multiple bodies, rather than genetics).

Frankie has visible stitches all over her body, most obviously near the joints of her limbs, around her neck, and across her right cheek. She also has two bolts fixed into her neck, which allow her to absorb electricity to use as energy to keep her body working. In some episodes, she displays the ability to command electricity as well as absorb it via her neck bolts without warning, causing things to get pretty freaky.


Frankie is friendly, sweet, and polite with a clumsy streak. She is the naivest of all the girls; being so young, so she tries to learn all she can about the world through monster teen magazines, although their advice often causes awkward moments for her.

Despite setbacks, she remains upbeat, hopeful and determined to find her place within Monster High.

Frankie can also be insecure and react too quickly, such as instantly labeling Abbey Bominable as rude and accusing one of her friends of being the Ghostly Gossip.

Classic Monster

Frankie is the child of the Frankenstein's Monster and his bride; The influence of her parents in her physical appearance can be seen in Frankie's skin color, stitches and neck bolts (from her father as depicted in films), and her black and white hair and red lips (from her mother as depicted in films). Frankie also has a fondness for the lightning bolt symbol, which is seen frequently in the films as the method of animating the monster.

The character of Frankenstein's monster first appeared the 1818 Gothic novel, Frankenstein; or, The Modern Prometheus, written by English novelist Mary Shelley. The novel tells of Victor Frankenstein, who builds a creature in his laboratory but upon bringing the creature to life, Frankenstein flees from it in horror and disavows his experiment. Abandoned, the monster wanders through the wilderness searching for someone who would understand and shelter him. The novel has since been the subject of many adaptations, mostly in film.

In 1935, Universal released a sequel to their popular 1931 Frankenstein adaptation. The sequel was titled Bride of Frankenstein and was directed by James Whale and starred Boris Karloff and Elsa Lanchester. In this film, it is revealed that Frankenstein's monster has survived the pursuit of the angry mob from the last film, and he persuades his maker, Dr. Frankenstein, to create a mate for him. This film introduced the concept of Frankenstein's bride to the public, and her appearance in this film - including her iconic, white-striped hair - has become a popular portrayal of the character.

Frankie mentions multiple times in the diaries and webisodes that her parents, especially her father, "made her", as in created her from body parts as the monster were in the novel and films. This suggests that (within the Monster High universe) either the characters of Dr. Frankenstein and his monster are the same person, or the monster was educated in science, similar to Dr. Frankenstein.

Frankie's Age

There are several plot-holes concerning Frankie's age in the series. If the webisodes follow the same timeline as the New Ghoul @ School special, she would have started school when she was 8 days old or younger. In Party Planners, she turns 16 days old. For her to be consistently 16 days old, most of what happens in the webisodes would have had to have happened in the same day, although this can't be, as in Frightday the 13th she stayed overnight, which means she is a day older than what she is now.

Over the course of the first book, Frankie is at least 30 days old. The diary included with the San Diego Comic-Con International 2010 exclusive doll describes her first day alive, while the regular diaries start on the day, she has just turned 16 days.


In the music video for the Fright Song, there are several character analogues who received creative interpretation by the video crew. The "Hero Zombie Girl" is portrayed by Angela Duscio.

In the webisodes and specials, Frankie's voice is provided by Kate Higgins.

"New Ghoul @ School" centers around Frankie's first week at school. Though this is considered independent and non-canon, it offers a new insight to Frankie's insecurity and desperation of friends. She messes up several times, even almost ruining Cleo and Deuce's relationship by lying about Deuce being her boyfriend. However, in the end, Frankie drops her superficial facade and tries to make everything right.

In "Fright On!", Frankie is one the biggest supporters of monster equality. Being naive to the feuds between monster races, Frankie sees no reason why anyone should fight. With the disappearance of Bloodgood and rising tension between the newly merged schools, Frankie puts herself in danger to save her friends. After stopping a fight between Vampires and Werewolves, and then offering a deep, motivational speech on why they should get along, Frankie saves the school and fuses the bonds between the monsters.

In "Why Do Ghouls Fall in Love?". Frankie is first seen as the narrator. In the storyline itself, Frankie takes a few steps back from the spotlight, and is really only seen for motivation and for thinking up ideas.



Frankie lives with both of her parents in "a house that looks like a cross between a Swiss chalet and a research lab". Her dad is a scientist, and both her parents treat her like she is very young (which, of course, she is, being only 15 days old) but they are very kind to her as she learns about the world around her and finds everything scary cool.

Her parents are only mentioned once in the webisodes, when Frankie makes a video of her time at Gloom Beach. They have a bigger role in the books; her parents Vicktor and Viveka Stein are both college professors and monsters like Frankie. Her parents do not approve of her speaking to Holt Hyde because he is too old for her, but they love Jackson Jekyll, unaware as Holt and Jackson are the same person.


Frankie is best friends with Draculaura, Clawdeen Wolf, Lagoona Blue, Abbey Bominable, Cleo de Nile, and Jackson Jekyll. She has no monsters she considers enemies, even trusting manipulative characters like Toralei Stripe and Cleo without question; more than likely, this is due to her naive nature.


Frankie's pet is a dog hybrid named Watzit which her father constructed from the parts of other animals.

In the books, Frankie has five pet lab rats whom she calls the Glitterati; their names are Gwen, Gaga, Green Day, Girlicious and Ghost Face. They also appeared in "New Ghoul @ School" and "Fright On!".


In the television movie "New Ghoul @ School", Frankie had a crush on Deuce Gorgon. This caused issues when she lied and told Deuce's real girlfriend, Cleo, that she was dating him. Cleo became very upset, thinking that Deuce had cheated on her, but the issue was later resolved when Frankie came forward with the truth and surprised Cleo with a Justin Biter concert.

In "HooDoo You Like?" Frankie was concerned about being left out of the group for not having a boyfriend, and decided to make one for herself, creating Hoodude Voodoo. The ghouls explained that they would always be friends with her regardless of whether or not she had a boyfriend, and Frankie admitted that she didn't think that she was ready for boys just yet.

In the webisode "Miss Infearmation" Frankie develops a crush on Jackson Jekyll after saving him from being bullied by Manny Taur and invites Jackson to come to Cleo's tomb party with her. She is upset when he doesn't show up in "Hyde and Shriek", because he had turned into Holt Hyde before entering the party.

She soon forms a crush on Holt, blushing at the nicknames that he gives her ("'Freaky Fine' Stein", "High-Powered Hottie") and dances with him on the DJ deck in "Hyde and Shriek". This forms a love triangle between her, Jackson and Holt. After introducing the two to each other via video recording in "Dueling Personality", she realized she couldn't choose and "hit the pause button" on their relationships.

In her School's Out diary, she has a crush on a Scottish gargoyle that plays football. She calls him "7", since she cannot remember his name.

Frankie has had a crush on Neighthan Rot in the movie Freaky Fusion, which is mutual, but they never actually dated.


In the books, Frankie had a crush on the monster-loving normie Brett Redding, who was dating Bekka in the first book. As Brett was already taken, Frankie briefly dated DJ Hyde, but it ended in the second book after she and Brett became interested in one another. To her relief, Hyde broke up with her, saving her further relationship problems.

After their monster identities are revealed, Frankie assumes that Brett set it up and seemingly broke up with him. In the third book she became a bit interested in Billy after he became "visible", but that ended in a mutual break-up after she rekindled with Brett yet again and saw that he was innocent and on the same side as the RADs.


In the Monster High books, Frankie is the daughter of university professors Viktor and Viveka Stein, and a grandchild of the original Dr. Frankenstein. The first 15 days of her life is spent having basic world and academic knowledge downloaded into her head. She is taught to hide her abnomal looks to appear more human; she learns to cover her "mint" green skin with makeup, hide her neck bolts with high collars, turtlenecks, or scarves, and has to wear a tracksuit for the rest of her body. Melody mentions in the second book that her style of dress is 'worthy of a nun'.

In the books, her hair is completely black, although her white streaks are later briefly created using peroxide. Frankie hates hiding who she is and makes many attempts to get humans to accept her for who she is. However, she eventually ends up exposing her RAD world to panicked humans and the rest of the RAD community want her excommunicated. At the end of Monster High, she befriends DJ and Melody, who support her and also want to help the RADs.

By The Ghoul Next Door, she's on house arrest like the rest of the RADs, and most of the stuff she bought is taken away by her parents. When Brett got out of his shock (after the police declared Frankie's exploits as a prank) he and Melody thought of an idea, to help the RADs coexist with the Normies, by making a movie 'Ghoul Next Door.' Later in the second book Frankie breaks up with DJ (Frankie was re-interested in Brett, and Holt's visits were prevented by Jackson). Both were relieved to hear that.

In Where There's a Wolf, There's a Way, after Ghoul Next Door backfired, causing most of the RAD's and their families to move far away from Salem, Frankie's family was not one of them due to not being directly in the documentry. Afterwards, she broke up with Brett temporarily and got together with Billy to see Lady Gaga in concert, only to be with Brett again. She was present at Clawdeen's party flaunting her RAD status.

In the fourth book, Frankie and Cleo compete in a contest to get a million dollars for Merston High, the contest nearly breaks the friendship between the two ghouls.
