Rafael Fonteriz began working in advertising. He started making short comics in his spare time, just for his own pleasure. He had his first professional work published in the juvenile magazine Camacuc. He then did an erotic album called 'El Legado', and the series 'X-Women' for Kiss. He teamed up with Jesús Yugo and began 'Efecto Dominó' in El Víbora. He became one of the most recent illustrators of 'El Capitan Trueno', and took on the 'Avatar' trilogy with writer Juan Miguel Aguilera.
