In October 2020, MLW would begin incorporating story elements from the defunct Lucha Libre promotion and former television drama, Lucha Underground. Talent formerly associated with Lucha Underground were brought into MLW as part of the "Azteca Underground" stable.[5][6]
On November 8, 2021, MLW announced that it would be holding its second co-promoted event with The Crash at the Auditorio Fausto Gutierrez Moreno in Tijuana, Baja California, Mexico on December 3.[2][7]
The supercard featured professional wrestling matches scripted by MLW and The Crash featuring wrestlers involved in scripted feuds. The wrestlers portrayed 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 performed.[8][9]
