a wrestling match or series of matches. At AAA's previous major event, Rey de Reyes on March 18, 2012, rudo stable El Consejo picked up their first win in AAA, when Máscara Año 2000 Jr., El Texano Jr. and Toscano defeated Dr. Wagner Jr., Electroshock and Heavy Metal in a six-man tag team match, with Máscara Año 2000 Jr. pinning Wagner Jr. for the win, following interference from El Consejo'''s masked accomplice El Hombre de Negro ("The Man in black"). In the weeks that followed Rey de Reyes, Máscara Año 2000 Jr. kept making challenges towards Wagner Jr. for a singles match, while El Consejo as a whole also feuded with Chessman, Silver King and Último Gladiador of rudo stable La Sociedad. This would, on April 30, drive longtime rivals and real-life brothers, Wagner Jr. and Silver King to make peace with each other and team up against Máscara Año 2000 Jr. and El Texano Jr. After losing as a result of another interference from El Hombre de Negro, the brothers shook hands to signal the end of hostilities between the two.

On June 30, Máscara Año 2000 Jr. defeated Wagner Jr. in a singles match with help from his father, after which the Mask vs. Mask match was made official for Triplemanía XX.
