Dennis Raymond Alexio is an American former kickboxer 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 WKA World Super Light Heavyweight Full Contact Championship match in 1984. He rebounded from this by winning the PKA World Light Heavyweight title that same year before moving up to cruiserweight and taking the 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, for a short time, considered the undisputed World Heavyweight Champion. He faced the two toughest tests of his career in 1992 against Branko Cikatić and Stan Longinidis, both who were heavier fighters fighting to a controversial draw with Cikatić and losing to Longinidis via an early low kick KO.
