Proclaimed by many renowned masters to be the greatest pound-for-pound kickboxer of all time, Benny Urquidez was nicknamed "The Jet" because of his explosive spinning back kick. After competing for ten years in non-contact point karate, he pioneered full-contact fighting throughout the world, often fighting in bouts where the rules were ambiguous and contrasts in styles were dramatic. In the 1970s, he won the PKA and WKA World Kickboxing Championships, and then went on to defeat Japan's World Champion. Highlighting his stellar career that spanned two decades, Urquidez came out of semi-retirement at the age of 42 to seal his legendary status by defeating Japan's 25-year-old reigning World Champion. Victorious in six World Championships in five different weight divisions, Benny "The Jet" Urquidez has remained undefeated for 27 years as the longest reigning World Champion ever.
