Roberto Fuentes

Roberto Fuentes was a martial-arts writer and co-author best known for partnering with Piers Anthony on the Jason Striker series, a run of pulpy 1970s men's-adventure novels following a judo and martial-arts expert drawn into international crime and combat. The five core Jason Striker novels appeared in a rapid burst between 1974 and 1976, at the height of the decade's martial-arts fiction boom that followed the mainstream popularity of kung fu films, with a sixth entry, Curse of the Ninja, following decades later in 2001. Fuentes brought technical martial-arts knowledge to the collaboration, and the Jason Striker books are noted for their detailed, enthusiast-level depiction of judo, karate, and other combat disciplines woven into their globe-trotting crime plots — a level of technical grounding that distinguished the series from more generic men's-adventure paperbacks of the era. The partnership represents one of Piers Anthony's early-career work-for-hire collaborations, written well before Xanth established Anthony as a bestselling solo author, and it remains the primary body of published fiction Fuentes is credited with. Detailed biographical information about Fuentes beyond his work on Jason Striker is limited in the public record.
