All tournaments have taken place in Arena México in Mexico City and all were held on Fridays during CMLL's Super Viernes show.
Only the second half of the match was shown on television, which means that the order of the first eight eliminations is only known to the people in attendance at Arena México that night.
The match came down to Shocker and Tarzan Boy, at the time both mid-card wrestlers hoping to move into the main event picture.
Universo 2000 pinned Canek to win the tournament, gaining a small measure of revenge on the man that beat him for his mask only three weeks prior at the CMLL 71st Anniversary Show.
The winner of the tournament would also be considered the first CMLL World G1 Heavyweight Champion and win a place in New Japan Pro-Wrestling's (NJPW) upcoming G1 Climax tour in August, 2005.
The final match saw Lizmark Jr. pin Último Guerrero to earn both the Leyenda de Azul trophy and the CMLL World G1 Heavyweight Champion.
CMLL used the same tournament format as the previous year as they had the winner of the first and the last match of the first round face off in the finals.
[21] The eighth Leyenda de Azul tournament took place on October 12, 2012, on CMLL's Super Viernes show.
The finals of the match saw Atlantis eliminate long time rival Último Guerrero to win the tournament.
The match ended with Último Guerrero pinning Valiente to eliminate him and win the Leyenda de Plata for the first time.
