 Over the following years, Dos Caras developed both physically and style wise into a heavyweight wrestler, blending the "Lucha libre" style of wrestling with a more mat-based, United States style wrestling style.Years later author James Molinaro cites Caras' blend of several wrestling styles as one of the reasons he called him "the greatest heavyweight ever to come out of Mexico" On February 2, 1984 Dos Caras won the highest title in the UWA as he won the UWA World Heavyweight Championship by defeating Enrique Vera in a tournament for the vacant title.Dos Caras' first run as the headliner of the UWA lasted for 119 days, until June 24, 1984 when he lost the belt to Canek.
