Alain Perwez (better known as Péral) studied fine arts in Liège. He also studied at the Saint-Luc in the same city. He entered the comics field with the help of Olivier Saive, doing among others coloring work. He then settled in Luxembourg, where he worked in the animation field for three years (among other on the series 'Crobs'). Back in Belgium, he became an assistant to Daniel Kox on the series 'L'Agent 212' for a while. He also began illustrating children's books. He took over the artwork of the series 'Billy the Cat' from Stéphane Colman in 2002.
