Olivier Supiot's comics career started when he won the Graine de Pro prize at the Angoulême festival in 1997. Some of his pages then appeared in Fluide Glacial. A year later, 'Erzurum' appeared at Le Cycliste publishers, a story for which he wrote the scenario. He then teamed up with writer Eric Baptizat, with whom he launched the 'Marie Frisson' series. This series, about a girl in an absurd world with crazy monsters, appears from 1999 at Glénat publishers. The series also appeared in Tchô! and Console Mania. With Eric Omond, he launched 'Nosfératu' in Fluide Glacial, as well as 'Le Dérisoire' in the collection Carrément BD of Glénat in 2002. He works with Boris Beuzelin on the series 'Le Narval', which is published by Treize Étrange from 2010.
