15: Hector Garza, Tarzan Boy and Terrible won the belts after just a couple feuds of with the champions. There didn't seem to be any particular plans for this unit, a make shift one, and the belts may have only been defended once before the team quietly split. There never was an in-ring break up, but the team was divided between members of the Guerreros del Atlantida faction (Tarzan Boy) and Los Perros del Mal (Hector Garza, Terrible), and the two factions started feuding against each other in 2005. The championship was rarely mentioned from 2005 until the decision match to decide new champions.
Vacant (4): It was announced on the September 16, 2006 CMLL television show that a decision match would be held for the champion on September 29th, the CMLL Anniversary show.
In February of 2008, Los Perros turned on Hector Garza when he protested Averno and Mephisto inclusion in the group. The trios championship situation was not addressed for three months past until a title tournament was announced after the May 23rd show.
18: Despite never having teamed previously, Hector Garza led young tecnicos La Mascara and Hijo del Fantasma thru the championship tournament, climaxing with an upset win over Blue Panther, Dos Caras Jr., and Garza's then tag team championship partner Mistico. It was a rare tecnico/tecnico final, seemingly setting up issues between Garza and Mistico and Garza's new role as a leader of a group of high flyers.
Neither idea seemed to gain much traction, and neither did this trio on it's first trip thru. The unit did not team up unless they were about to lose a non-title match or win a title defense. While it did give more attention to Mascara and Fantasma, they were still used lower on the cards and wouldn't naturally find chances to team with their leader. Just as this team won the championship without teaming previously, they lost to a team who had not teamed up previously.
19: Continuing the pattern, Negro Casas, Ultimo Guerrero and Atlantis won the CMLL Trios Championship as a three top wrestlers who happened to be teaming together on that night, and not as previously established unit. In fact, Negro Casas was already in an established unit (Pesta Negra) and the other two were in a totally separate unit (Guerreros del Atlantida). Winning the trios championship fuzzied the distinction between those two groups and caused the Guerreros to lose members (Sangre Azteca & Olimpico) who were upset about being passed over for a non-member like Negro Casas.
What this team did not have in team strength, it did make up for thru having a genuine Mexico City feud for the championship. As part of the CMLL/TNA partnership, and spilling out of the events of the 2008 Gran Prix, a trio of TNA wrestlers challenges for the trios titles at the 75th Anniversary show. The champions held on, despite Ultimo Guerrero not getting revenge on rival Alex Shelley.
In a surprise, this trio lost the belts back to those who had beat them.
