Background
The Crash Lucha Libre began operating on 2011, focusing mainly on promotion professional wrestling event in Tijuana, Baja California, Mexico. Their first show was held on November 4, 2011 with a main event of El Hijo del Santo and Latin Lover defeating El Hijo del Solitario and Marco Corleone. The Crash held shows on a limited schedule over the next couple of years; 4 in 2012, 4 in 2013, 2 in 2014, and 5 in 2015.

Storylines
The Crash X Aniversario show featured six professional wrestling matches scripted by The Crash with some wrestlers involved in scripted feuds. The wrestlers portray either heels (referred to as rudos in Mexico, those that play the part of the "bad guys") or faces (técnicos in Mexico, the "good guy" characters) as they perform in the ring.
