Frank Dux

Frank W. Dux (pronounced "dukes") is an American martial artist and fight choreographer. Dux established his own school of Ninjutsu in 1975, called "Dux Ryu Ninjutsu". He was the inspiration for the 1988 film Bloodsport starring Jean-Claude Van Damme.^[1]

Dux states that he was introduced to and trained in Koga Yamabushi "Ninjitsu" by Senzo "Tiger" Tanaka.^[2]

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."^[2] Frank Dux formulated the proprietary augmentation technology he calls DUX FASST (Focus-Action-Skill-Strategy-Tactics). (Wikipedia).

Frank Dux fought 329 matches between 1975 and 1980.  He retired undefeated as the World Heavy Weight Full Contact Kumite Champion. Dux still holds four world records:

Fastest Knockout - 3.2 seconds

Fastest Punch with Knockout - .12 seconds

Fastest Kick with Knockout - 72 mph

Most Consecutive Knockouts in a Single Tournament - 56

Moral of the story is that Frank Dux is super bad-ace and that his crabtastic skills in the ring are unmatched by any mortal.
