—Mylène, "Horrificator"

Click here to see quotes from Mylène Haprèle.

Mylène Haprèle is a student in Miss Bustier's class at Collège Françoise Dupont.[2] 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.

As of recent Season 4 spoilers, Mylène will wield the Mouse Miraculous. It is currently unknown what her superhero name is.[3]


Physical appearance

Mylène is short and chubby with blonde dreadlocks with some strands dyed green, blue, or magenta. 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 golden brown eyes.

Civilian attire

She wears a pink bandana to hold her hair back, and she has a necklace with a stone pendant. She wears a periwinkle shirt with a white silhouette design on the front of a bird holding a branch with leaves, which is underneath an olive green hoodie jacket. 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 dark gray jean shorts, black 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. The top half of her body is mainly pink, and the bottom half, along with her forearms, are mainly purple. She has three yellow eyes with red pupils, the third eye being in the middle of her forehead, and has periwinkle tentacles with spots on the back of her head. Her head has freckles; her mouth has sharp, jagged white teeth; and her tongue is light blue. She has dark purple claws on her hands, while the claws on her feet are brown, the toes being tan-colored. She has a long purple tail. The pin that Ivan gave her is attached next to one of her head tentacles but is hidden by her pink goo.

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 try to look for the best in people.

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, her bravado and confidence are gone, leaving her terrified by the others and running into Ivan's arm for comfort and protection.


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 Mouse Miraculous Holder

She will most likely have the same powers as the most recent holder, Multimouse: enhanced physical abilities, a Jump 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.

Mylène has romantic feelings for Ivan. Once she gets to know him, 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 also comforts her again in "Captain Hardrock" when Anarka is akumatized.

Fred Haprèle

Mylène expresses pride in her father's work.

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

Marinette Dupain-Cheng/Ladybug

Mylène gets along well with Marinette and enjoys hanging out with her. As of "Despair Bear", Mylène has 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 is 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. 

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

As with Ladybug, like her friends, Mylène 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.

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.
  • 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.
  • In her webisode, "Mylène", it is revealed that she is interested in politics and would like to make Paris a better place for its inhabitants.
  • Horrificator reappears in the two-part special event "Heroes' Day".[4]
  • Horrificator appears another time in "Gamer 2.0" for Gamer's powers.
  • As of Season 4, Mylene is the second known person of French origins to wield the Mouse Miraculous succeeding Multimouse.
