Frank Dux born in Toronto, Canada, in 1956, is the eldest son of Holocaust survivors. In the early 1960’s, the Dux family settled in the heart of California San Fernando Valley, what is referred to by martial art scholars as the “Valley Of Champions.” Since the San Fernando Valley is where leading martial art trade magazine and book publishers were located, becoming a figurative Mecca for leading Martial Art Masters and Competitors. Most of which, were teaching within a short distance of each other.

Unable to afford the tuitions to formally enroll in commercial schools shaped Frank Dux into becoming the Mixed Martial Art archetype, not fixated on pursuing any one style. Acting contrary to the then popular belief of puefecting “purity and tradition;” what Bruce Lee referred to as the “Classical mess.” 

Frank Dux began his study by auditing the various styles of such greats as Bill Ryusaki, Bob Ozman, Bong Soo Han, S.B. Moon, John Leone and many other martial legends. Frank Dux who studied from them, stood on the outside looking in, the sidewalk his mat. In a 2002 documentary on no-holds-barred Kumite (that forms the basis of Bloodsport and MMA) Grandmaster Bill Ryusaki, sidekick to Bruce Lee and teacher to such Champions as Cecil Peoples and Benny “The Jet” Urquidez, says:

“Frank was just a kid then…he cleaned the sidewalk and kept the Ryu-Dojo windows clean and I kept my blinds open for him to watch and learn, I’d try to send someone to invite him in but he would leave before he would give me a chance to speak.” - Grandmaster, Bill Ryusaki

In 1969, in Pasadena, Victor Moore defeated the thought unstoppable Mike Stone. Stone had accumulated 91 straight wins and never placed anything but, first place. At this time, Frank Dux who was a teenager, but big, about 5'10", asked Moore if he recognized him from Ed Parker’s Long Beach Invitational, where Moore defeated Bruce Lee in a test of speed.

Moore says he thought nothing of it. Frank was so tall and physically developed he didn’t realize Frank’s real age. For Frank Dux it was a desperate attempt to grab attention to find a teacher. Dux politely asked Moore if he recalled what he told Dux two years earlier “To be the best you have to fight the best.” Then politely asked if he could fight Moore. Moore laughed it off and told him offhandedly to go ahead and take his best shot. Dux obliged him. Dux threw a back knuckle and landed a hit striking Moore on the nose.  Just hit him, boom, and threw another and they fought for ten or fifteen minutes, no officials, says Moore.

“Finally, there was no winner, everybody who was around just hooting and hollering, they couldn't believe what took place.  Mike Stone, who had just got beat, his shoulder broken by me in the first round from being swept and there's Frank Dux, an overgrown awkward looking kid taking me on, matching my speed, power and determination, it impressed me and everyone watching him”

John Keehan’s AKA Count Dante Black Dragon Fighting Society members who were accompanying Moore were apparently so impressed they officially initiate Frank Dux making him the youngest member in its illustrious history says BDFS President Michael Felkoff, Head of Family Dr. Lawrence Day and BDFS Spiritual Leader Rev. Don Miskel. Spiriting Frank Dux into hitchhiking in his teens to Chicago to be coached by them and one of Keehan’s instructors, James Lee AKA Sanzo Tanaka.

Fast-forward 35 plus years later, and seeing each other in a Nashville, Tennessee Hotel Lobby, Vic Moore takes his revenge. Moore playfully saying, “Hey, we ain’t done yet!” Throwing a back knuckle to Frank’s nose.  The two break out reenacting from memory their first then last fight that had more resembled a fight to the death, in Texas. His most memorable and toughest fight of his career proclaims, Vic Moore.

“Not trying to take anything away from Bruce Lee, Bill ‘Superfoot’ Wallace, Joe Lewis, Chuck Norris, Jim Kelly and Mike Stone are just a few of the great fighters I fought and defeated as a World Champion. But my two most memorable fights I ever had are with the only guy I couldn’t beat, Frank Dux. I would say to him this is what I am going to do and pop him and I‘d say you ready I’m gonna do it again and I’d do it… but then, he would give it right back to me. He’d better me with my same combo… and every combo I used he adapted and made it his own and better… I was fast as they come, but Frank Dux was faster. FASTER THAN ALL OF US BACK THEN, including Bruce Lee. I told everyone this was the up and comer to watch.”  - Grandmaster, USKA & PKA World Karate Champion, Victor Moore.

Eventually, through his association with the Black Dragon Fighting Society Frank Dux came to be formally enrolled in classes with Jack Sanzo Seki and later with the legendary Sanzo “Tiger” Tanaka.

Sanzo Tiger Tanaka is a former member of the Kokuryukai (Black Dragon Society) that was an industrial spy ring in China that with Chambers of Commerce sponsored no-holds-barred full contact fighting events. The Black Dragons Society of Japan used this as an opportunity to spot and recruit fighters to act as enforcers for them, prior to Japanese Invasion. He is the gateway for Frank Dux’s introduction to Ninjutsu and his participating in the elite by invitation only Bloodsport fighting event. Sanzo Tiger Tanaka’s existence and the event is a matter of common knowledge in Chinese martial art community, as is portrayed in the Jet Li true to life story Fearless.

Fearless is loosely based on the life of a famous early 20th century Chinese martial artist Hou Yuanjia who challenged foreign fighters in highly publicized events, restoring pride and nationalism to China at a time when Western Imperialism and Japanese manipulation were eroding the country. The true to life film depicts Frank Dux instructor Sanzo Tiger Tanaka who became renowned for putting an end to the reign of Hou Yuanjia bare-knuckle fighting dynasty in “San Soo” AKA “The Kumite” event that’s historical origins can be traced back to Mongolian nomadic tribes of Genghis Khan, then known as “Bandizo.” Tanaka’s victory as well as BDFS members having participated in these events secured the necessary invitation for their pupil Frank Dux to be allowed to compete and reign as champion of the closed door event a generation later, as is depicted in the 1988 film, entitled: Bloodsport.

Sanzo Tiger Tanaka taught alongside famed Ninjitsu master Fujita Seiko at Nakano spy school, in China. His relation Kushiage Tanaka is recoded by the Imperial War museum as head of Japanese Intelligence in 1930’s England, where then Deputy Minister of MI5 Ian Flemming came to know of the exploits of Tiger Tanaka and in paying him homeage as he did likewise others in his books transformed him into a fictional character in the franchise James Bond book You Only Live Twice.

Head of Family of Black Dragon Fighting Society, Lawrence Day and Patriarch Donald Miskel remember Frank Dux and Sanzo Tanaka, in Chicago, with John Keehan a.k.a. Count Dante.

"Master Tanaka is the source of most of John Keehan's knowledge of Death Touch "Dim Mak" and Poison Hand. He learned this when the average person in those days had no access to that level of knowledge because John was adopted into master Tanaka's lineage. This was handed down to several choice students in the Black Dragon Fighting Society, namely Dr. Lawrence Day, Ernie Reynolds, Michael Felkoff and eventually given to Frank Dux by hand's on training by Sanzo Tiger Tanaka. However, much was put in holding of Dr. Lawrence Day to be passed on to Frank Dux when he came of age and a few other chosen students. We knew Tanaka had served as an agent in early stages of events that led up to World War II. Because of his past and what was now frowned upon during the reconstruction period of Japan after the war he was wanted for questioning and lived under assumed identities. My personal contact was minimal but much of the knowledge was passed down to me by my seniors in his Black Dragon Society and lineage.  Tanaka saw in Frank his fighting spirit and took him under his wing and the rest is history" - Grandmaster, Donald Miskel. 

While Sanzo Tiger Tanaka is considered by some to be a Japanese martial art legend, he was said to lose favor when he married a woman of Irish American, descent. The mother of Jujitsu legend Jack Sanzo Seki was also Irish.

Frank Dux says:

“Sensei Seki, was one of the few guys who put on a program where you could attend classes for a buck and a quarter ($1.25) a month. It was low enough that if I could collect bottles… I would turn them in to the local liquor store and get a nickel. That was basically me finding two bottles a day on my way home from school.”

Despite his skill in martial arts, Frank states he was quiet and timid.

“I had a few friends, not many. High school was rough. I did not fit in. I was wearing combat boots, a military fatigue jacket and two pair of jeans that I had to make do with. I couldn’t go out for sports, I had to work if I was to go to college or for me and my family to just eat at the end of the day” – Hanshi, Frank Dux

Jack Sanzo Seki was born in Los Angeles, Ca. on July 7, 1914 and in 1943 his name was legally changed to Jack M. Hayward. Jacks's father was Japanese and his mother Irish (note Tiger Tanaka'a wife was also Irish). Jack was relocated in Japan at an early age by his father Sanzo Seki who was born in 1888 and died in 1975 (coincidentally, this date of birth and death corresponding to Sanzo Tanaka's date of birth and death).  Whilst Jack's father Sanzo Seki was a Jiujitsu master he sent his son Jack to train with Dr. Jigoro Kano, an expert in Tenjinshino Ryu Jujitsu and Kito Ryu Jujitsu and the founder of modern Judo. Those who knew him indicate Jack Seki was awarded a Sandan (3rd Degree Black belt) in Judo by Kano. After studying with Kano Jack returned and mastered the martial arts as taught by his father. In 1960's he was USKJ's USA Jujitsu Champion. When not teaching jujitsu at YMCA and Los Angeles Valley College Jack Seki worked for Lockheed Aircraft. Allegedly part of its "skunks work" secret project division.  jack's work associates state they believe Jack had been enrolled at Doshiisha College in Kyoto, Japan.   Prof. Seki was a dedicated instructor as well as student of martial arts, always learning. He held Yudansha grades in Judo, Karate, Aikido, and Ju-Jitsu, which he tested for and earned in Japan.

One of the great mysteries in martial arts is how Sanzo Jack Seki's father (1888 – 1975) like Sanzo Tanaka was not only a reputed Ninjitsu and JuJitsu master but Kung Fu master trained by Shaolin Monks in China, in 1920s-30s and a member of the Society of Black Dragons, the umbrella under which the Kokoryukai Black Dragon Society is a faction. After reputedly living in mid-west and California, just like Sanzo Tanaka, Jack's father allegedly he returned to Japan where he died, September 1975. The corresponding events lends us to believe that Sanzo Tanaka and Sanzo Jack Seki's father were one in the same person.



In 1980 Frank Dux came to the attention of Black Belt Magazine, who featured Frank Dux in their September, October and November issues of the magazine. In the November 1980 issue, John Stewart editor of Black Belt magazine wrote the article entitled: "Kumite: A Learning Experience".

"From time to time, BLACK BELT learns of unusual events or occurrences in the martial arts; events that-either because of their nature or because they occurred in the distant past- cannot be easily verified. Because we don't want our readers to be misinformed, BLACK BELT has a policy of strict verification of all facts pertaining to any article. In the case several members of the staff have invested considerable amounts of time and energy checking the details of the following article, which was the product of a series of four interviews conducted over a period of three months. Although there is no convenient way to verify each and every detail connected with this story, the editors have verified enough of the basic facts to feel confident in publishing it." - John Stewart Black Belt magazine nov. 1980

Also in 1980 in a letter, Rainbow Publication's Black Belt Magazine editor, John Stewart wrote:

"Dux is a fully knowledgeable consultant on the details of such subjects as full contact fighting, weapons techniques and anti-terrorism." Stewart goes on to say that "Dux has had military experience of a unique nature."

According to FOIA documents, in 1975 Frank Dux served in the United States Marine Corp as an Intelligence Specialist (MOS 0200). The Intelligence Occupational Field (OccFld) in the Marine Corp conducts the collection, processing, and dissemination of intelligence. The specialties within the Intelligence OccFld are analysis, counterintelligence, imagery interpretation, and geographic intelligence.

Intelligence specialists are required to learn and master a variety of analytical and technical skills. Formal schooling and NOT OJT (on job training) is mandatory for being an intelligence MOS as well as basic rank requirement. Marines entering the OccFld will receive MOS 0200, Basic Intelligence marine, while participating in on-the-job training (if required) in addition to attending formal school.

Military document experts, like Sean Dalton, state under penalty of perjury that inconsistent statements and forged entries establish the FOIA military service record of Frank Dux is what is more commonly referred to in their exert opinion as a front file. Frank Dux real military record is in all likelihood sealed and may not be acquired via FOIA request but require a legal proceeding conducted in federal court, where a need to know must accompany any records request. Typically, when the US government goes through the trouble of inventing a front file, said requests made within 50 years of last dated entry, end up denied as matter of record.

Following in the footsteps of his own father who was a former operative as well as Frank Dux teacher, Sanzo Tiger Tanaka, Frank Dux began his intelligence career. A fact corroborated by means of official statements issued by foreign military authorities as well as in testimony of domestic intelligence operatives, during court proceedings that’s records are available online for a fee [e.g. Frank Dux vs. Robert Brown, Alexander McColl, Larry Baily and Soldier of Fortune Magazine, Case No: BC198883, Superior Court Of California, Los Angeles County etc.]

For instance, Major General, Anatoly Korneinko, USSR, acting as an official spokesperson of Ukrainian (Former Soviet) Military Authority declared:

“In early 1983 I received an order from the military command to provide necessary assistance and cooperation to a joint military group known then as Officer Duchovny’s Group. This group was to carry out military operations in Soviet territories under my command. The leader of the group, “Officer Duchovny” was Frank Dux …Frank Dux was dubbed the Hunter. He was in the Soviet Union for just a few weeks when our intelligence received information about the exceptional talents of the Hunter and his unique ability to investigate extremely dangerous and complicated matters.” - Major General, Anatoly Korneinko, USSR

Major General Anatoly Korneinko corroborates Frank Dux leveraged his martial art relationships into having been entrusted to take part in a Top Secret Operation. That’s success or failure potentially determined the deployment of weapons of mass destruction.

Lt. Cmdr. Alexander Martin USN (ret) testified before the Kerry committee and every single investigating committee in Congress from 1987 until 1990 on the Iran-contra Affair. According to Lt. Commander Alexander Martin USN, in 1985, Frank Dux was officially identified as a covert intelligence operative, in Honduras.

Major General Richard Secord was a United States Air Force officer convicted for his involvement with the Iran-Contra scandal. In 1984, Maj. General Secord mandated that Lt. Cmdr. Martin USN (ret) raise funds as well as form a series of corporations by which to legitimize the flows of money to what Oliver North described as "the cause" and what Secord described as "the enterprise;" a covert effort to support and maintain the Contra army within the border of Nicaragua.

With regards to Frank Dux involvement in Iran Contra, Lt. Commander Martin USN corroborated this under penalty of perjury, identifying Frank Dux as a covert intelligence operative, Lt. Cmdr Martin USN, testifying:

During my intelligence career, I have met with and been introduced to many covert operatives, whose existence has often been officially denied by the government agencies that these parties have been associated with. One of these covert operatives was one Frank Dux. Mr. Dux and I met in Tegucigalpal, Honduras, in the summer of 1985, where I was being briefed by Dux and other intelligence operatives on military targets within Nicaragua. These targets included the planned mining of a Nicaraguan port and the planned sabotage of certain Nicaraguan installations including power stations and weapons depots, codenamed OPERATION CORDOBA HARBOR.”

By 1986 the 1980 Black Belt Magazine article entitled "Kumite" became the catalyst for beginning the movie Bloodsport with Jean Claude Van Damme portraying Dux, who was trained by Sanzo Tanaka, played by Roy Chiao, who trains Frank Dux to fight in an event that takes place once every five years, called “The Kumite.”

Frank Dux sidekick in the movie is Ray Jackson played by Donald Gibb. The Ray Jackson character was based upon Kyokushinkai Swedish Kumite Champion Kurt Peterson and Wally Jay Small Circle Jujitsu Black Belt, Richard Robinson. Robinson transformed himself from being a biker in Venice, California, to a prominent stockbroker for Montgomery Scott, in Philadelphia. Robinson also founded a million dollar facility that teaches numerous Japanese koryu martial arts in Pennsylvania - The River of Life Martial Arts and Wellness Center.

Lastly, in the movie, the Kumite is depicted as taking place in Hong Kong however according to the Nov. 1980 issue of Black Belt magazine, the Kumite was actually held at a private residence in the Bahamas. Given its 1.5 million dollar budget the theatrical film Bloodsport was a great success at the box office and has developed a cult following since it's initial release, in 1988. It is considered by many film critics as well as martial art authorities to be one of the greatest Martial Arts films ever made, surpassing in audience views and frequency it is replayed, Bruce Lee’s Enter The Dragon.

Bloodsport sequels were made without the Frank Dux character, using a Jean Claude Van Damme lookalike named Daniel Bernhardt. They went straight to video. Attributed to their lacking Frank Dux input as a fight choreographer (which Dux performed in original) as well as straying from the based on true events story resulted in the franchises failure. Bloodsport fan clubs complain they felt cheated, desiring the return of Frank Dux story and character.

Frank Dux states he is in general agreement with Ninja Museum of Japan, Ninjitsu is not in actuality a specific martial art system per se but an umbrella word. One used to describe when one combines budo (way of war) with psychology, magic, pharmacology, medicine, and espionage (intelligence gathering) and strategy activities (strategy to lower the enemy’s ability to fight). There are esoteric and those martial aspects of Ninjitsu handed down by which to employ sticks, ninja throwing stars and farm implements as means of self-defense but the image of a fighting, sword-swinging ninja is relegated to history, the movies and the world of comic books. ttp://

Based on his understanding and personal beliefs that traditional Ninjitsu is inferior, Frank Dux did not abandon it entirely but embraced its principals and based on his own empirical knowledge established the first American system of Ninjutsu, Dux Ryu Ninjitsu and DUX FASST (Focus, Action, Skill, Strategy and Tactics). Due to its ferocity and measurable effectiveness, the DUX FASST tactical application system is only transmitted to elite Law Enforcement and Military personnel.  A fact corroborated by Glock Monroy, the tactical advisor who teaches defensive tactic instructors at Mexico City Police Department’s Police Institute. Monroy is President of the professional association governing the teaching of defensive tactics in Mexico as well as in other countries throughout Latin America, FISMDC (Federacion International de Sistemos Mixtos de Defensay y Combate.A.C). Glock Monroy states:

“Mexico’s elite law enforcement agencies invested considerable resources and time in evaluating and utilizing DUX FASST. We found it provides a startling measurable and decisive advantage. So much so, that when being taught in Police Institute in Mexico City, all of its practitioners are fingerprinted and photographed.  They must enter into individual confidentiality agreements stating that if the officer is discovered transmitting DUX FASST in any unauthorized manner they risk being discharged from the department as well as risk criminal prosecution. We hold it in such high regard… Frank Dux has refined close quarter combat into an exact science, identifying specific laws and formulas that will reproduce the same result, time and again. And yet, are flexible to meet the consistently changing nature of combat.”

Gary Swanhart, Coordinator of MCTFT (Multi Jurisdictional Counter Drug Task Force Training) with over 25 years of law enforcement experience, stated under penalty of perjury in court proceedings "Dux has been utilized as a quest speaker for the NEOA (Narcotics Enforcement Officers Association). Dux has also been utilized as an adjunct instructor for the Criminal Justice Institute in St Petersburg. Fl…”

Detective John Krupinskey, Danbury Police Department, Board of Directors of the Narcotics Enforcement Officer's Association as well as being a member of the Danbury Police Department's S.W.A.T (Special Weapons and Tactics) team, stated under penalty of perjury, in court proceedings:

"In 1995 Dux's experience was put to the test by the Danbury Police Departments S.W.A.T. Team both as a participant in various training scenarios and by solving highly technical and hazardous tactical problems that were indigenous to the area.

In 1996, because of Frank Dux's unique experience and expertise in conducting covert operations, Frank Dux, through efforts of the Multi-Jurisdictional Task Force (MCTFT) in St. Petersburg and the federal funding of Mr. Dux's expenses, Mr. Dux was invited to be the keynote speaker-instructor at our annual Criminal Investigations school then held in Springfield, Massachusetts.

Mr. Dux instructed a class on officer safety undercover operations and planning to approximately 200 highly experienced officers and detectives. As a matter of NEOA policy each speaker and instructor was reviewed and criticized in a questionnaire provided to each of the attending officers.

Mr Dux's presentation, based upon receipt of these written reviews, received the most outstanding ratings possible from and remarkably, by each of the attending officers and detectives."

Frank Dux has been identified in police industry magazines as the keynote speaker for Federal Law Enforcement Officers Association, 2010 annual conference.

Notably, Frank Dux has trained elite military units worldwide. In as much as, he is named as one of the source contributors to the U.S. Naval Special Warfare Combat Fighting Course (NSW CFC) Handbook (K-431-0097) prepared by The Naval Special Warfare Center in San Diego, Ca.

This is corroborated by the fact that the SPECWAR manual lists Dux name on pg 10, identifying him as a source contributor to the Naval Special Warfare Combat Fighting Course Manual. This is further corroborated in court proceedings where a SpecWar teacher to teachers, Shane Ludwig, identifies Frank Dux as training him.  From 1985 to 1996 Ludwig was a member of the Naval Special Warfare community, a SEAL Instructor (Basic and Advanced) with operational experience deployed as a US Navy SEAL. Ludwig under penalty of perjury states, in support of court proceedings:

"…beginning in 1995, Frank Dux trained me at the Naval Special Warfare Center and participated in our development of the Naval Special Warfare Combat Fighting Course for which he is named a contributor NSW CFC manual K-431-0097, intended for special forces personnel only."
