2006 International Wrestling Revolution Group event
El Castillo del Terror (2006) was the second annual El Castillo del Terror professional wrestling event produced by the International Wrestling Revolution Group. It took place on November 2, 2006, at Arena Naucalpan in Naucalpan, State of Mexico. The show featured the eponymous main event match; a nine-man Steel Cage Match where the last two men in the cage were forced to wrestle each other and the loser would be forced to unmask under Luchas de Apuestas, or "Bet rules". For the 2006 event Ave Fénix, Bacteria, Fabián el Gitano, Fantasma de la Ópera, El Felino, El Hijo del Diablo, Macho II, Nitro and Xibalva all wagered their masks on the outcome of the match. The match came down to Ave Fénix and Macho II, with Fénix pinning Macho II to force him to unmask afterwards.
