El Castillo del Terror (2012)

Starting as far back as at least 2002, the Mexican wrestling promotion International Wrestling Revolution Group (IWRG; Sometimes referred to as Grupo Internacional Revolución in Spanish) has held several annual events where the main event was a multi-man steel cage match where the last wrestler left in the cage would be forced to either remove their wrestling mask or have their hair shaved off under Lucha de Apuestas, or "bet match", rules. From 2005 IWRG has promoted a fall show, around the Mexican Day of the Death, under the name El Castillo del Terror ("The Tower of Terror") to distinguish it from other Steel cage matches held throughout the year such as the IWRG Guerra del Golfo ("Gulf War"), IWRG Guerra de Sexos ("War of the Sexes") or IWRG Prison Fatal ("Deadly Prison") shows. The Castillo del Terror shows, as well as the majority of the IWRG shows in general, are held in "Arena Naucalpan", owned by the promoters of IWRG and their main arena. The 2012 Castillo del Terror show was the eighth year in a row that IWRG promoted a show under that name.

The event featured five professional wrestling matches with different wrestlers involved in pre-existing scripted feuds, plots and storylines. Wrestlers were portrayed as either heels (referred to as rudos in Mexico, those that portray the "bad guys") or faces (técnicos in Mexico, the "good guy" characters) as they followed a series of tension-building events, which culminated in a wrestling match or series of matches. The Main Event was a 12-Man Steel Cage Match. The last two wrestlers who remained in the ring fought one on one in a Lucha de Apuestas Match ("Bet match"), wagering their mask on the outcome of the match. The event included wrestlers from International Wrestling Revolution Group (IWRG), Lucha Libre AAA World Wide (AAA) and a number of Mexican Freelance wrestlers.
