Overview:The event was originally scheduled to take place on October 10, 2020 but was postponed and later cancelled on November 30 due to the COVID-19 pandemic. However, on October 18, 2021, AAA announced that the event would be occurring on December 4 at the Estadio de Béisbol Monterrey in Monterrey, Mexico.[2] It marked the 29th year in a row that AAA has held a Triplemanía show, and the 36th overall show held under the Triplemanía banner since 1993. The annual Triplemanía show is AAA's biggest event of the year, serving as the culmination of major storylines in what has been described as AAA's version of WrestleMania or their Super Bowl event.
