Oscar Martín (Barcelona, 1962) made his debut in the mid-eighties, designing "Tom & Jerry" for the German company Condor; at the end of the decade he also debuted as a Disney designer, working until the 2000s mainly for the Dutch and Danish markets. At the beginning of the nineties he created "Il mondo terrificante di Bobby" for Semic and in 1996 he became art director of the Spanish magazine "Zona X". In 2002 he received the Lifetime Achievement Award from Warner for his Tom & Jerry stories, which he continues to draw.

In 2005 he began to draw the series "La Gilda", for the French Casterman, based on texts by Miroslav Dragan, published in Italy by ReNoir Comics, as well as his very personal work "Solo": the epic of an anthropomorphic warrior mouse in a post-apocalyptic world, the "Cannibal World", which has spawned several spin-offs.
