He was born in Barcelona, the son of a Spanish comic book artist, Miguel Bernet. He made his debut in comics at fifteen, continuing his father's humorous series Doña Urraca after his death in 1960, under the pseudonym "Jordi". While this could support his family, it did not satisfy his artistic ambitions that were inspired by artists such as Hal Foster, Alex Raymond and Milton Caniff. From 1962, Bernet developed a more realistic style, and took on smaller assignments from Italian and British publishers, until he started illustrating for the Franco-Belgian comics magazineSpirou in 1965. He drew the series Dan Lacombe with his uncle Miguel Cussó as writer, and created a similar series Paul Foran with writer José Larraz, but due to disagreements over editing decisions by Dupuis, Bernet ended the relationship with Spirou. Turning to the German market, in the 1970s he collaborated with Cussó to create Wat 69, a sexy and humouristic heroine for the magazine Pip, and Andrax, a science fiction series for Primo, which both became successful in Germany.
Later work
After the fall of Franco, Bernet returned to Spain and worked for several Spanish comics magazines such as Creepy, Metropol and Cimoc, eventually meeting three writers with whom he would form productive partnerships. With Antonio Segura he created the amazone fantasy seriesSarvan, and the series Kraken, depicting a sewer monster terrorizing a futuristic fascist society. . Bernet first collaborated with Enrique Sánchez Abulí on several short stories, collected in Historietas negras. When Alex Toth, after producing two stories of Torpedo 1936 in 1981, decided he did not share Abulí's darkly humorous view of mankind and parted with the project, Bernet was asked to continue the work. This became the beginning of a long-lasting series, which became a popular success and was awarded at the Angoulême International Comics Festival. It eventually formed the basis of its own magazine, Luca Torelli es Torpedo in 1992. Later collaborations with Abulí include De vuelta a casa, La naturaleza de la bestia: Ab Irato and Snake: por un puñado de dolares. Bernet also formed a creative partnership with the Argentine writer Carlos Trillo, resulting in the sexually explicit series Cicca Dum-Dum, the less lewd and more comical series Clara de noche, and several one-shots, including Custer, Light and Bold and Ivánpiire. Bernet's more recent publications include several albums for the Italian western character Tex Willer, and a run of work for the U.S. comics market, including a Batman story, and a trilogy detailing "the shocking origin" of Jonah Hex. Bernet has later continued to work with Jimmy Palmiotti and Justin Gray on Jonah Hex''. American artistWill Eisner described his impression of Bernet's work in an anthology preface:
