[16] In September 2011, Rey Escorpión competed in that year's version of the Leyenda de Plata tournament, but did not make it past the qualifying Torneo cibernetico match held as part of the CMLL 79th Anniversary Show, as he was eliminated by Olímpico.
The tournament saw Rey Escorpión team up with rival Black Warrior, furthering the storyline between the two as their inability to get along caused them to be eliminated by Marco Corleone and Último Guerrero.
[21] Two weeks later, the team were unsuccessful in their challenge for the CMLL World Trios Championship, which only furthered the issues between Escorpión and Los Guerreros.
