Frank Dux
Frank W. Dux (pronounced "dukes") is a martial artist and fight choreographer. Dux established his own school of Ninjutsu in 1975, called "Dux Ryu Ninjutsu". An article about his purported exploits, which appeared in Black Belt Magazine in 1980, was the eventual inspiration for the 1988 film Bloodsport starring Jean-Claude Van Damme.
Martial arts career
Dux states that he was introduced to and trained in Koga Yamabushi Ninjitsu by Senzo Tanaka. Dux's martial art style, Dux Ryu Ninjitsu, is not a koryu (15th century feudal form of Ninjutsu), but is still claimed to be "based on its Koga Ninja root principles of adaptability and consistent change". Frank Dux formulated the proprietary augmentation technology he calls DUX FASST (Focus-Action-Skill-Strategy-Tactics).
The accuracy of many of Dux's personal claims have been disputed, including his martial arts background, fighting in the "Kumite", and prior military service. According to the Los Angeles Times, the organization that allegedly staged the Kumite had the same address as Dux's house, and the trophy he claims to have won was bought by him at a local trophy store. This was disputed by Dux, who claimed that the receipt was fabricated. He also claims that his critics are part of a conspiracy to discredit him, led by ninjutsu master Stephen K. Hayes, whom Dux claims views him as a threat.
