In Mexico, Guerrero joined a gym with the intention to learn to box, but instead learned lucha libre from Diablo Velasco and El Indio Mejía. He wrestled his first professional wrestling match on September 14, 1937, jobbing to El Rojo. He began his career in Mexico working under the ring name Joe Morgan, but later changed his name to Gory Guerrero—a reference to his bloody matches. He made his debut for the Mexico City promotion Empresa Mexicana de la Lucha Libre in 1943 and was named "Rookie of the Year" later that year. In 1945, he briefly held the Mexican National Welterweight Championship. Several months later, he won the Mexican National Middleweight Championship, which he held for approximately one year. Guerrero and his brothers also feuded with Cavernario Galindo and his brothers. In the late 1940s, Guerrero began tag teaming with El Santo as the undefeated La Pareja Atómica. Guerrero also appeared in some of El Santo's films. He also feuded with Enrique Llanes and his tag team partner Tarzán López. He defeated Lopez for the NWA Middleweight title. In 1954, he wrestled a championship match against NWA World Heavyweight ChampionLou Thesz but did not win the title. Guerrero broke away from EMLL in 1966 after refusing to drop the NWA World Light Heavyweight Championship to Ray Mendoza. He worked as an independent in the mid-1960s. He also began to branch out into booking and training with Dory Funk Sr.. In addition, he helped run shows in NWA Hollywood Wrestling for two years, and later he booked shows for World Class Championship Wrestling. With age his in-ring performing decreased until his ultimate retirement in the 1980s. Guerrero is credited with the invention of La de a Caballo and the Gory Special, a type of backbreaker. He also invented the back to back stretch hold which has been modified into a facebuster move, a piledriver, a powerbomb, a reverse STO or a neckbreaker/backbreaker.
