Panchito was born in Paco, Manila. His mother, Etang Discher, became a prominent film actress beginning in the 1940s, often being cast in villainous roles. One of his brothers, Emil Tagle, also became a film actor. He was married with children. His aunt, Elaina Discher, was also a Filipina actress. Panchito's career in show business began in 1942 when he joined a bodabil troupe called "Travel Stage Show" which performed in various theaters in Japanese-occupied Manila. The then-14-year-old Dolphy was also a member of the troupe, thus beginning a lifelong association.
