Hanshi Frank Dux founded Dux Ryu, the first American system of ninjitsu. Although Dux Ryu is rooted in traditional ninjitsu, experience in no-holds-barred competitions forced Hanshi Dux to adapt, improvise, and change his fighting in order to dominate in his fights. His system of triangulation and angles-of-attack helped him defeat traditional linear or circular movement styles. Hanshi Dux was the 1975-1980 World Heavy Weight Kumite champion and is the holder of 16 world speed and power records. He is a qualified instructor in 22 disciplines and was the inspiration for the movie "Bloodsport." He has also been inducted into the Martial Arts Hall of Fame.
