Último Guerrero
In early 1993, then-CMLL booker Antonio Peña decided to leave the promotion and start his own professional wrestling promotion, Asistencia Asesoría y Administración (AAA); when Peña left CMLL, he acquired a number of wrestlers, among them the then-reigning Mexican National Tag Team Champions, Misterioso and Volador, leaving CMLL without a Tag Team title. In response, CMLL created the CMLL World Tag Team Championship to fill the void. On March 3, 1993, Canek and Dr. Wagner Jr. won a tournament to become the first CMLL World Tag Team Champions. The team of Negro Casas and Shocker hold the record for the longest reign as a team at . Último Guerrero and Rey Bucanero hold the record for the longest combined reigns of any team: 1,185 days divided over three reigns. Individually, Negro Casas has held the championship six times for a total of 2,577 days, the longest of any champion. The team of Último Guerrero and Dr. Wagner Jr. held the championship for seven days, the shortest reign of any champion. Negro Casas and Último Guerrero have the most title reigns with six each, while the combinations of Último Guerrero and Rey Bucanero and Averno and Mephisto are the only teams to have won the championship three times.
