Miguel Gallardo is an innovative artist of Spanish comics. He began his career in the late 1970s and had his first success in May 1977 when he co-created 'Makoki' in Disco-Exprés magazine. Makoki was a psychopath who escaped from a mental hospital. In 1979, this character was transferred to the magazines Star and Bésame mucho. The same year, Gallardo became an artist for the El Víbora periodical.
Teaming up with Juan Mediavilla, he continued making renewing comics, featuring such characters as 'Tío Emo', 'El Niñato' and 'El buitre Buitaker'. With their series they developed a style that soon got the humorous name "línea chunga", a purely Spanish comic style. In 1982, when the publisher of El Víbora launched 'Makoki' magazine, Gallardo not only participated as an artist but also as editor of this magazine.
