The 2005 Leyenda de Plata is the only tournament to not feature the previous year's champion defending the trophy, playing off Aguayo's breaking of the trophy the previous year. The lack of defending champion forced CMLL to change the format of the Leyenda de Plata as they held two eight man ciberneticos instead of one 16-man, with the winner of each cibernetico facing each other the following week. The two cibernetico format has been the standard tournament format for the Leyenda de Plata ever since 2005. The first cibernetico took place on October 28, 2005 and featured El Hijo del Santo, Hombre Sin Nombre, La Máscara, Volador, Jr., Misterioso, Jr., Jado, Averno and Negro Casas. The match came down to Hijo del Santo and Casas and initially ended in a double pin. After the match was restarted El Hijo del Santo won by submission. The second cibernetico took place on November 4 and saw Atlantis outlast a field that also included Místico, Último Dragón, Máxmio, El Sagrado, Mephisto, Hijo de Pierroth and Gedo. On November 11, 2005 Atlantis defeated El Hijo del Santo with help from his corner-man Último Guerrero to win the seventh Leyenda de Plata.
