After working as a commercial artist, André Amouriq began his career in comics. He started out retouching American material for Impéria publishers. He published his first stories in pockets like Ringo and Nic et Loup, published by S.E.P.P., as well as Ranger, Rex and Rhapsodie, for which he drew 'Baf' in 1975. For the publisher Lug, he drew stories with 'Le Petit Trappeur' from 1978 through the late 1980s. He drew an episode of 'Mikros' in Mustang and in a more adult register, he drew 'Titi Fricoteur' in Bédé Adult, using the pseudonym Gast.
Amouriq illustrated 'Le Petit Monde de Pétassine' for Albin Michel in 1992. He made a comic adaptation of the cartoon series 'Carlos' for Canal + Éditions and in 1996, he created 'Clarisse' for Le Progrès de Lyon. He participated in several collective albums for Soleil and created series like 'Les Zyperes' (2000), 'Les Prédictions de Nostra' (with Cazenove, 2001) and 'L'Auto-École' (with Cazenove, 2004) for Bamboo.
