Born in the Andalusian city Lorca, José-Luis Munuera attended the School of Fine Arts in Granada. He made his debut with 'No Hay Domingos en el Infierno' at the Spanish publisher Lunáticos in 1995, but subsequently focused on French publishers. At the festival of Angoulême he met Joann Sfar with whom he began a collaboration on series like 'Les Potamoks' (Delcourt, 1996-97) and 'Merlin' (Delcourt, 1999-). Munuera was additionally working for Bayard Presse, illustrating 'Sam Trot' in J'Aime Lire.
In 1999 he teamed up with scriptwriter Jean-David Morvan and created 'Sir Pyle S. Culape' in Lanfeust Mag. Morvan also took over the scriptwriting of 'Merlin' in 2002. In 2000, Munuera made a comic adaptation of the Dreamworks film 'The Road to Eldorado' for Dargaud in 2000. Also with Morvan, he created 'Nävis' in cooperation with Philippe Buchet, telling the youth of the principal character from 'Sillage' (Delcourt). Between 2004 and 2006, Munuera and Morvan created three new albums for the classic series 'Spirou et Fantasio' in succession of Tome and Janry.
