Mathieu Reynès was born in the Paris region in 1977, but spent his childhood on the Basque coast. After several years of studying science in Bordeaux, he turned his attention to cartoons and 3D animation by joining CNBDI Angoulême, first as a student and then as a tutor. After a few years, he decided to devote himself to comics. His first album, "Banana Fight" was released by Paquet in 2002, in collaboration with script writer Frédéric Brrémaud . The duo then created 2 volumes of the series "Sexy Gun" (éditions Soleil) and three volumes of "Lola Bogota" (Bamboo). Afterwards he produced several comedy series also published by Bamboo, all co-written with Brrémaud: "Les tennismen" (illustrated by Bertolucci, 1 volume published), "Les informaticiens" (illustrated by Toulon, 4 volumes published), "Toutou & Cie" (illustrated by Soffritt, two volumes published) and "Les Maîtres Nageurs" (3 volumes published) that he illustrated himself. In 2007, Mathieu Reynès embarked on the adventure of "Alter Ego" alongside Denis Lapière and Pierre-Paul Renders. Meanwhile, he wrote the script to the album "La Mémoire de l'Eau", illustrated by Valérie Vernay, which was released in 2012 by Dupuis.
