In the early 1990s Los Infernales reformed, reuniting MS-1, Satánico and Pirata Morgan. The trio participated in the tournament to crown the first ever CMLL World Trios Champions. Los Infernales won the tournament, defeating Los Brazos in the finals to become the first ever CMLL World Trios Champions on November 22, 1991. Former Infernales member Masakre had formed his own group, Los Intocables ("The Untouchables") consisting of himself, Pierroth Jr. and Jaque Mate ("Checkmate"). Los Intocables were immediately paired with Los Infernales to create a rudos vs. rudos storyline, playing off both the championship chase and the history between the two groups. On March 22, 1992 Los Intocables won the CMLL World Trios Title, however Los Infernales got the final victory in their feud as they defeated Los Intocables for the championship on September 20, 1992. After the storyline with Los Intocables ended Los Infernales renewed their rivalry with Los Brazos, facing off in several main events that drew sell-out crowds all over Mexico. On April 6, 1993 Los Brazos won the CMLL World Trios Title from Los Infernales; a victory that only helped increase the intensity of the rivalry. The Infernales / Brazos feud did not end with a conclusive victory for either side but rather slowed down and then stopped when Los Infernales split up in the mid 1990s. Both Satánico and Pirata Morgan left CMLL for periods of time to work for Asistencia Asesoría y Administración, CMLL's main rival and in 1996 MS-1 left CMLL for good.
