Born in 1972, Nicolas Kéramidas was hired in 1993 at Walt Disney Studios in Montreuil, a highly formative experience where he had the opportunity to explore various drawing styles. Collaborating with Didier Crisse on a nine-volume series, Luuna tells the adventures of a young Native American and marks his first published series with Soleil. Kéramidas then signed on for three volumes of Tykko des sables with Arleston for the same publisher. He also contributed to an episode of the Donjon series written by Joann Sfar and Lewis Trondheim. In 2012, he launched the trilogy Alice au pays des singes with Tebo at Glénat. In 2016 and 2018, he illustrated scripts by Lewis Trondheim for Mickey's Craziest Adventures (2016) and Donald's Happiest Adventures (2018). In 2021, he collaborated once again with Joann Sfar for Commando Barbare (Glénat) and then, in 2022, with Lewis Trondheim for Superino (Dupuis). In 2020, he published his first solo comic book, À Cœur ouvert, with Dupuis, based on an operation he underwent. Chasseur d'Invader is his 22nd album and his 2nd as a complete author.
