No, Ladybug! I can't be a superhero. I'm scared of everything. Look, I have a badge for my fear of water, one for my fear of beasts. I need a necklace to help me get over my fear of badges!

—Mylène, "Mega Leech"

Mylène Haprèle is a student in Miss Bustier's class at Collège Françoise Dupont.[4]

In "Horrificator" after feeling humiliated for getting scared easily while filming Nino Lahiffe's movie, she gets akumatized by Hawk Moth and becomes Horrificator, a monster supervillain.

In "Gang of Secrets", after Marinette keeps hiding secrets from them, Mylène is re-akumatized by Shadow Moth into Horrifcator along with Reflekta, Princess Fragrance, Timebreaker and Lady Wifi, the five supervillains all form the Gang of Secrets, a group of supervillains who want to reveal Marinette's secrets.

In "Mega Leech", in order to defeat Malediktator and his titular sentimonster, Mylène receives the Mouse Miraculous from Ladybug. When the Miraculous is inhabited by Mullo, Mylène becomes Polymouse, a mouse-themed superhero who helps Ladybug and Cat Noir during "particularly difficult missions" in the fourth season.[5][6][7][8]

After the events of "Strikeback", Mylène will temporarily be unable to become Polymouse after Hawk Moth manages to steal the Mouse Miraculous along with all the others contained in the Chinese Miracle Box from Ladybug's yo-yo.


Physical appearance

Mylène is quite short and chubby with blonde hair styled into dreadlocks with some strands dyed strong malachite green, vivid cornflower blue, and brilliant rose. A dreadlock on the left side of her head has a purple cat bead; another dreadlock on her right side has a golden loop and moderate gamboge eyes and pale magenta lipstick.

Civilian attire

She wears a pink bandana to hold her hair back, and she has a necklace with a stone pendant. She wears a brilliant azure T-shirt with a white silhouette design on the front of a pigeon holding a olive tree branch with 3 leaves, which is underneath an grayish lime green jacket with a hood. There are pins attached to her jacket: on the right side, she has a daisy pin; on the left side, she has a ladybug pin, a panda pin, and a yellow and green pin. Additionally, she wears moderate tangelo jean shorts, very brown leggings, and dark purple and white sneakers. She is often seen wearing the pin that Ivan gives her in the episode Horrificator.

As Horrificator

Horrificator is a large salamander-like monster with a long brilliant purple tail. The top half of her body is mainly brilliant fuchsia, and the bottom half, along with her forearms, are the same color as her tail. She has three brilliant amaranth eyes with light brilliant gold scleras, the third eye in the middle of her forehead, and has very pale blue tentacles with spots on the back of her head. Her head has freckles; her mouth has sharp, jagged white teeth; and her tongue is pale, light grayish arctic blue. She has dark purple claws on her hands, while the claws on her feet are brown, the toes being pale, light grayish gamboge. The pin that Ivan gave her is attached next to one of her head tentacles but is hidden by her slimy goo.

As Polymouse

As Polymouse, Mylène has moderate green eyes, and her hair is still braided, but is light brilliant rose-colored and shorter, tied into a pigtail in the back of her head, which is hidden by a medium gray jacket with a hood which bears mouse ears with light pink insides. She wears a medium gray mouse-themed turtlenecked jumpsuit with a pale pink front, starting from her collar to her thighs. And pale pink gloves and boots with light amaranth borders, fingers and soles, which have magentaish black mouse footprint markings. And a light gray face mask with pale pink eyelids and borders, and a brilliant crimson accent on the bridge of her nose, resembling a nose. The skip rope, when not in use, is tied in her hips, resembling a mouse's tail. The gray material of her costume seems to be iridescent as it shines pink in some lighting.

Myléne grateful for the pin from Ivan.

Mylène is a meek and cordial girl. Although she tries to be brave, she is easily frightened by anything that she sees as scary, which she is ashamed of and even cries about in "Horrificator". She also is sensitive to being made fun of and is hurt by Chloé's mean remarks about her. She appreciates kindness, and she speaks very fondly of those she loves. According to Marinette in the webisode with the same name, Mylène always tries to look for the best in people.

As Polymouse, Mylène's personality mostly remains the same, but she shows more confidence and bravery.

As Horrificator, she relishes in making everyone scared (as opposed to her being scared). Aggressive and menacing, she attacks everyone and doesn't like it if any of them aren't freaked out by her. Despite this, she retains her feelings towards Ivan and refuses to harm him. When she is calmed down, by the song Smelly Wolf, her bravado and confidence are gone, leaving her terrified by the others and running into Ivan's arm for comfort and protection.

When akumatized a second time as Horrificator, she, along with Lady Wifi, Reflekta, Princess Fragrance, and Timebreaker, want to expose Marinette's secrets in hopes of saving her and to be friends again by forcing her to give them up. While Lady Wifi claims Horrificator will keep Ladybug and Cat Noir, she does want to save Marinette so they can be friends again. She and the Gang of Secrets have no qualms putting bystanders in danger to find Marinette, such as scaring others to make herself stronger so she'll capture Marinette. Her desire to persevere their friendship is so intense that she, Princess Fragrance, Reflekta, and Timebreaker chase after an illusion of Marinette instead of taking Cat Noir's ring.


As a civilian

Mylène is a decent actress, being chosen for the leading role in the class's film. However, it's hard for her to stay in character when she is scared by something, like Ivan's mask.

As Polymouse

Polymouse has the same powers as the most recent holder, Marinette: enhanced physical abilities, a Skip Rope as her tool, and Multitude as her superpower.

As Horrificator

Horrificator can spit a very resistant purple goo that she uses to block exits and trap people. Whenever she catches people, she brings them to her lair and traps them inside hardened cocoons. Whenever people scream in fear upon seeing her, she grows larger, but if they aren't scared, stay calm or calm down, she shrinks and eventually becomes as small as a house cat. The larger she is, the stronger she gets, and she can make use of her tail by grabbing people with it.

Ivan Bruel

Myléne telling Ivan that she loves the lyrics he wrote for her.

Despite initially scared of his intimidating look, Mylène came to develop strong romantic feelings for Ivan. Once she gets to know him and see the tender heart he has, she isn't terrified by his appearance, and they treat each other very sweetly.

In "Ladybug & Cat Noir" and "Stoneheart", Ivan gets akumatized when he is teased by Kim because he doesn't have the courage to confess to her. In the second part, he is akumatized because she runs away from him, scared by his loud rock serenade. After transforming for the second time, Ivan kidnaps her and climbs the Eiffel Tower holding her in his fist, much to her frustration and fear. He is then defeated thanks to Ladybug tying them together to make them kiss as a distraction. After transforming back, Ladybug gives Mylène the lyrics to Ivan's song; she is so touched by them that she hugs him, making him blush profusely.

Ivan comforting Mylène as they worry about Darkblade.

In "Horrificator", she appreciates Ivan's attempt to console her after she was insulted by Chloé, but she ends up crying and running away to the bathroom anyway. Once akumatized, she doesn't attack Ivan, licking his face instead. After shrinking, thanks to her calming song "Smelly Wolf", she runs into Ivan's arms, and after transforming back, they kiss. In "Darkblade" when she and her classmates are in the Hôtel de Ville under siege by Darkblade and his knights, she gets close to Ivan, and he hugs her to comfort her. They dance together at Chloé's party in "Despair Bear". He comforts her again in "Captain Hardrock" when Anarka is akumatized.

She doesn't enjoy being apart from Ivan as seen in "Guiltrip" and always receives Ivan's support in anything she does and that includes her environmental protests, like Mayor Bourgeois' projects, such as the space dumpsters. Mylène always receives Ivan's support in anything she does and that includes her environmental protests, like Mayor Bourgeois' projects, such as the space dumpsters or Project Oxygen

Fred Haprèle

Mylène expresses pride in her father's work.

Mylène truly loves her father as she is proud of his acting abilities. She is really touched when he reveals that he keeps a photo of her inside the pouch of his hat as a good luck charm.

Fred also supports his daughter very much, as he came by to support her and her friends to protect the trees of the Place des Vosges from Mayor Bourgeois' Project Oxygen.

Marinette Dupain-Cheng/Ladybug

Mylène gets along well with Marinette and enjoys hanging out with her. As of "Despair Bear", Mylène has now become part of Marinette's close circle of friends, along with Alya, Alix, Rose, and Juleka. She is well aware of Marinette's crush on Adrien and supports her efforts in trying to woo him, such as in "Gigantitan", "Glaciator" and "Gorizilla". In "Glaciator" when she and Ivan go to André's to get ice cream with Alya, Nino and Marinette, Mylène was shown feeling sorry for Marinette after Adrien is unable to attend, leaving her heartbroken. In "Frightningale", Mylène shared in a group hug with Marinette when she turned down the offer to play Ladybug in Clara's video to be with her friends yet cheers her on when she changes her mind later on and takes the role.

During "Cat Blanc", Mylène wondered how Marinette's attempt to give Adrien her gift upon seeing her chicken out she cheered Marinette on when she tried again. Mylène was happy that Marinette was attempt was a success and even moreso that Marinette and Adrien were together but when time was reserved she praised her friend for the effort. In "Ladybug", like everyone else, Mylène was saddened that Marinette was expelled from school leading to her akumatization.

In "Gang of Secrets", she was aware that Marinette was heartbroken over her breakup over Luka and tried to console her but when it resulted in Marinette ending her friendship, Mylène was devastated to the point of being akumatized again. After was deakumatized, she was happy that they were friends again.

Mylène agrees to help Marinette, citing that she is always there for her friends.

As with Ladybug, like her friends, Mylène really admires the heroine's dedication to keep Paris safe. In "Gigantitan", she and her friends were willing to distract Gigantitan to prevent him from harming Ladybug.

In "Mega Leech", Mylène was called by the heroine for help. Aware of what Ladybug was trying to give her, Mylène rejects the offer of a miraculous stating she was no worthy superheroine. Soon, however, she tells her what true bravery what lies deep inside of her. Then she accepted the Mouse Miraculous being informed by Ladybug it will help her and the team with the mission.

Like the other members she follows Ladybug's orders without question and after the mission is over, Mylène returned the miraculous to the heroine.


Meeting Mullo for the first time, Mylène was scared of the kwami, who scared her on purpose which made her hide behind Ladybug. After the heroine explained Mullo's powers to Mylène, she transformed into Polymouse. When the mission was over, she returned the miraculous to Ladybug.

Chloé Bourgeois

Mylène is shocked when Chloé insults her sweater.

Just like the rest of her class, Mylène is weary of Chloé and her rude insults. In "Horrificator", Mylène runs off in tears after Chloé mocks her for being a scaredy cat, but she gets her chance to get payback later as Horrificator when she traps Chloé as one of her victims. She also tells Ms. Mendeleiev in "Antibug" that she isn't the one pulling Chloé's hair, which Chloé confirms. Even though she isn't particularly fond of her, Mylène willingly attends Chloé's party in "Despair Bear".

Comics and books



  • Mylène's first name may be a French variation of the name "Milena", which translates into "dearly". Alternately, it may be a combination of "Marie" (perhaps "sea" or "bitter" or "beloved, or reference to any of a number of literary Marys) and "Hélène" (likely "torch" or the electrical-discharge light show now commonly known as "St. Elmo's fire", or reference to any of a number of literary Helens).
    • In the Serbian dub, her name is changed to Milena.
  • Mylène's superhero form Polymouse, was originally called Multimouse.[9]
    • In the Italian dub, she's effectively called Multimouse instead of Polymouse.
  • As seen in "Stoneheart (Origins - Part 2)", she is scared of heights.
  • Whenever she needs to feel better, she sings "Smelly Wolf" to herself. Ladybug uses the song to stop Horrificator by singing it to her with Cat Noir and their remaining classmates.
  • Her akumatization appears to be heavily influenced by the movie the class makes in "Horrificator", as well as reshaping the movie.
    • Her akumatized form looks similar to the mask Ivan is wearing for the film.
    • Since her akumatized form is named after the movie's monster, this makes Mylène one of the villains that Hawk Moth technically doesn't name.
  • Along with the Mime, Horrificator is one of the two akumatized supervillains without a speaking role in Season 1.
    • Coincidentally, they are biologically related as father and daughter.

    • As seen in "Mega Leech", Mylène's politics-related activities include student protests and environmental activism.
  • Horrificator reappears in the two-part special event "Heroes' Day".[10]
  • Horrificator appears another time in "Gamer 2.0" for Gamer's powers.
  • Horrificator is probably based on the Xenomorph from the Alien film series.
  • The prefix "Poly" from her superheroine name "Polymouse" means more than one.
  • As of "Mega Leech", Mylène is the second known person of French origins to wield the Mouse Miraculous succeeding Multimouse.
  • She is the third person to initially reject a miraculous following Marinette and Zoé.
  • As seen in "Mega Leech", Polymouse is the sixth person to break an akumatized object, instead of Ladybug and Cat Noir, following Queen Bee, Rena Rouge and Carapace in "Mayura", Fang in "Lies" and Marianne Lenoir in "Furious Fu".
  • Following Alya Césaire, Nino Lahiffe, Chloé Bourgeois, Nathalie Sancoeur, Luka Couffaine, Max Kanté, Kagami Tsurugi, Alix Kubdel, Lê Chiến Kim, Adrien Agreste and Zoé Lee, Mylène is the twelfth person to become a Miraculous holder and akumatized villain, excluding Gabriel Agreste, who akumatized himself.
