History

AAA Mega Championship

Inaugural champion El Mesias

The title was introduced in 2007 via a single elimination tournament billed as the Torneo Campeón De Campeones (Champion of Champions Tournament), which effectively unified the IWC World Heavyweight Championship, Grand Prix Championship Wrestling (GPCW) SUPER-X Monster Championship, Mexican National Heavyweight Championship, and UWA World Light Heavyweight Championship. The tournament field included the four reigning champions of the aforementioned titles and the number one contender to each championship. IWC World Heavyweight Champion El Mesías became the inaugural AAA Mega Champion upon defeating UWA World Light Heavyweight Champion Chessman in the final.

Inaugural Championship Tournament bracket

In 2011, the then-AAA Mega Champion and Total Nonstop Action Wrestling (TNA) founder Jeff Jarrett appeared with a redesigned version of the title belt on TNA programming. TNA used the Mega Championship belt on their programming, but due to Spike TV, then TNA's broadcaster, not allowing TNA to refer to AAA by name, a silver hexagonal plate was used to cover the AAA faceplate. While Jarrett appeared in TNA, the title was referred to as the "Mexican Heavyweight Championship". On April 21, 2013, the title was defended outside AAA for the first time at Puerto Rico's World Wrestling League (WWL). In March 2015, the AAA Mega Champion El Patrón Alberto defended the championship in Lucha Underground, made possible through AAA's joint ownership of Lucha Underground.
