The inaugural champion was
Alex Koslov, who defeated
Alan Stone and
Xtreme Tiger at
AAA Television Taping on May 21, 2009, in
Aguascalientes, Aguascalientes. On August 17, 2014, at Triplemanía XXII, the Cruiserweight Champion Daga defended the title in a 10-man elimination match, where also participated the AAA Fusion Champion Fénix.
El Hijo del Fantasma won the match and unified both titles, deactivating the Fusion Championship and renaming the title as AAA World Cruiserweight Championship. On February 10, 2021, the champion
Laredo Kid faced the
Major League Wrestling's
World Middleweight Champion Lio Rush in a title vs. title match. Despite Rush winning the match and being recognized as champion, a few days later AAA did not recognize the title change. Instead, Laredo Kid appeared on AAA show with the title belt. According to Konnan, an AAA booker, Rush lost the title back to Laredo Kid in an un-televised match. On May 5, Laredo Kid appeared in
MLW Fusion with the AAA title, making an in-character statement where he refused to recognize Rush as champion.
