Obion was born in Concarneau. He started drawing at an early age, inspired by various artists of the magazine Fluide Glacial. Together with Kris, he began an atelier and a fanzine in Brest. He began working semi-professionaly on several comic projects, and took consults from Jean-Claude Fournier. With Kris, Obion drew for Pavillon Rouge and KR-OBart. Eventually, they began the fantasy series 'Le Désterteur', which is published in albums by Delcourt from 2003.
