The comics originally debuted in 1961 in the newspaper "Folha da Manhã", at first having as protagonists the characters Cousin Benny (Zé da Roça) and Taka (Hiro), but the comics changed after the introduction of Chuck Billy in 1963 who due to his popularity with the public, became the main protagonist after a few years.
