Julio Ribera Trucó started his career in his native Spain, working together with Pedro Alférez for several Spanish magazines under pseudonyms like Jules McSide and Bop. Ribera cooperated on Florita, a magazine for young girls, in 1945, and created 'Rosy'. He began a collaboration with Yumbo in 1950, and created series like 'Pepin y Sulfato' and 'Platillos Volantes'.
He joined Pilote magazine in 1965, where he started out illustrating several short stories and current affairs pages. He created the 'Dracurella' series in 1973, and continued it until 1979. In 1975, he teamed up with Christian Godard to create his best known series, 'Le Vagabond des Limbes'. The science fiction series appeared directly in albums at Hachette, but was later pre-published in Circus and Tintin.
While continuing 'Le Vagabond des Limbes', they created 'Le Grand Manque', which was reprinted at Soleil in 1993. When Vaisseau d'Argent folded in 1991, Ribera and Godard joined Dargaud publishers, where they created 'Le Grand Scandale' in 1994. Ribera produced 'Je Suis un Monstre' in the collection Grafica at Glénat in the same year.
In 2004, Ribera published 'Montserrat - Souvenirs de la Guerre Civile' at Bamboo publishers, the first part of trilogy based on Ribera's childhood memories of the Spanish Civil War.
