Mortelle Adèle is a French children's comic book series created by Antoine Dole under the pen name Mr Tan. Volumes 1–7 were illustrated by Miss Prickly, and from volume 8 onward by Diane Le Feyer. The series was published from 2012 until 2022 by Bayard Jeunesse, which had acquired editions Tourbillon and Milan. It is now published by Mr Tan & Co, the publishing house founded by Antoine Dole.
Mortelle Adèle follows the daily life of a little girl named Adèle with a strong personality, who casts a cynical and unapologetic gaze on the world around her. There is something of Mafalda and Wednesday Addams in her.
Background
Antoine Dole created the character of Adèle when he was 14 years old and a victim of bullying in middle school. He imagined the character as his opposite: a girl, while he is a boy, who dares to say everything, while he was shy. As a child, not wearing fashionable clothes, Adèle suffered the scorn of the popular kids, led by Jade and Miranda. To fight back, she founded the “Club des Bizarres” (Weirdos' Club), which brought together children who were a little different.
The values defended by Adèle and her creator Antoine Dole include tolerance, acceptance of strangeness, self-assertion, and refusal to conform to social norms.
In April 2018, six years after its launch, the series reached one million copies sold. By the end of 2019, over 2.5 million copies of the comic had been sold, including 1 million in 2019 alone.
In 2020, among the 10 best-selling comic books in France, four volumes were from the Mortelle Adèle series.
In early 2021, 13 albums from the series were listed among the top 20 weekly bestsellers in comics.
By March 2024, the series had reached 18 million readers.
In January 2025, Antoine Dole and Diane Le Feyer, co-authors of Mortelle Adèle, accused their former publisher, Bayard Jeunesse, of betraying their trust and misleading readers by continuing to exploit their work without consent. Bayard Jeunesse denied these accusations, calling them “baseless allegations.”
Main characters
Adèle She is the main character of the series. A little red-haired girl with long pigtails, she wears a school uniform reminiscent of those found in British schools. She spends her time conducting wild experiments on her cat. Impertinent and rebellious, she frequently disobeys adults and constantly invents new ways to impose her own rules.
Ajax
Ajax is Adèle's pet cat and, according to the story in Volume 1 (Tout ça finira mal), Adèle had asked for a baby lion—so her parents introduced Ajax as a “real baby lion,” only for her to discover that he's actually a kitten. Ajax becomes her experiment subject and unwitting punching bag ever since.
Her parents
They try daily to understand their daughter. Bewildered, they are usually at the mercy of Adèle's whims and struggle to make her obey—she never stops tormenting them.
