Benny Urquidez is an American former professional kickboxer, martial arts choreographer and actor. Nicknamed "The Jet", Urquidez was a non-contact karate competitor who later pioneered full-contact fighting in the United States. He made the transition from point to full-contact karate in 1974, the year of its inception in the US, frequently fighting in bouts where the rules were ambiguous and contrasts in styles were dramatic. Urquidez is also known for once holding the rare achievement of six world titles in five different weight divisions, and remained largely undefeated in his 27-year career. His only loss came in a Muay Thai match which was shrouded in controversy, as Urquidez had only agreed to a no-decision exhibition, a clause which was ignored when the fight had ended.
Dennis Raymond Alexio is an American former professional kickboxer and actor who competed in the light heavyweight, cruiserweight and heavyweight divisions. Starting out as a light heavyweight, Alexio kicked off his career with an extensive, knockout-laden undefeated streak before losing a decision to Don "The Dragon" Wilson in a World Kickboxing Association (WKA) World Super Light Heavyweight Full Contact Championship match in 1984. He rebounded from this by winning the Professional Karate Association (PKA) World Light Heavyweight title that same year before moving up to cruiserweight and taking the International Sport Karate Association (ISKA) World Cruiserweight Full Contact strap. In the late 1980s, he began his transition to the heavyweight division where he won six world titles and was considered the undisputed World Heavyweight Champion. He faced the two toughest tests of his career in 1992 against Branko Cikatić and Stan Longinidis - both of whom were heavier fighters - fighting to a controversial draw with Cikatić and losing to Longinidis via an early low kick KO which resulted in a broken leg.
