Wilfrid Lupano was born in Nantes, in the west of France, and spent most of his childhood in the southwestern city of Pau, France.

He spent his childhood reading through his parents' comic book collection and enjoying role-playing games. He studied literature and philosophy, receiving a degree in English, before he began to script comics.

He has written numerous graphic novels for French readers, including the series Les Vieux Fourneaux (in English, The Old Geezers). With this series, Lupano and Paul Cauuet first developed the idea that would become The Wolf in Underpants.

Paul Cauuet was born in Toulouse and grew up in a family that encouraged his passion for drawing. He was also a fond reader of classic Franco-Belgian comics such as Tintin and Asterix. He studied at the University of Toulouse and went on to a career as a cartoonist. Cauuet and Wilfrid Lupano first collaborated on an outer-space comedy series before working together on Les Vieux Fourneaux (The Old Geezers).
