Eric Liberge has collaborated on several fanzines since 1990. He soon joined the teams of the fanzines Le Goinfre and PLG, where he began doing graphic experiments. In 1996, he created his 'Monsieur Mardi-Gras Descendres' project, that first appeared in the fanzines PLG, Ogoun and Golem. The first album of this series was published by Zone Créative, but it was reprinted by Pointe Noire after winning the Prix René Goscinny in 1999. In 2004-05, the series was reprinted and completed in the collection Empreinte(s) of Dupuis.
Between 2000 and 2003, he began his series 'Le Dernier Marduk', at PMJ. As a scenarist, he teamed up with the young artist Vincent Gravé to make 'Ralayer' from 2001 to 2006. In 2003, he began the series 'Metal' at Soleil Productions, a publisher for which he had earlier created the one-shot 'Tonnerre Rampant' in 2002. With Denis-Pierre Filippi he created 'Les Corsaires d'Alcibiade' for the Empreinte(s) collection of Dupuis in 2004.
