Grégory Charlet was born in Valencienes, and grew up developing a growing interest in comics. He first studied Mathematics, but eventually got the opportunity, and the necessary funds, to enroll at the Academy of Fine Arts in Tournai. He participated on a book by the academy, called 'Envie de Fraise', in 1998. His participation got the attention of Eric Corbeyran, who suggested a cooperation. This resulted in the series 'Le Maître de Jeu', of which Charlet drew the first four books at Delcourt from 2000 to 2004.
