Olivier Fiquet entered the comics field after meeting Raymond Maric in 1987. He cooperated with Maric on several game pages for the magazine Fripounet. He then joned the publishing house Vaillant, where he did game pages in Pif Gadget and Pifou Découverte, as well as several covers for Parade. When Pif Gadget folded in 1992, Fiquet moved to Disney-Hachette, where he made puzzle comics starring 'Mickey Mouse' and illustrations.
He also drew 'Roger La Haine' in the newspaper L'Avenir. In addition, Fiquet worked in advertising and animation. He was present at the relaunch of Pif Gadget from 2004 to 2008 and came up with three new series: the football comic 'Le Derby', 'Mona Apprentie Détective', which he both wrote and drew, and 'Les Robinsons', for which Claude Bordeleau did the artwork. Since 2005, he is also co-author of new stories starring 'Pif et Hercule' with François Corteggiani.
