Arena Naucalpan 32nd Anniversary Show

The Arena Naucalpan 32nd Anniversary Show was a major annual professional wrestling event produced and scripted by the Mexican professional wrestling promotion International Wrestling Revolution Group (IWRG), which took place on December 17, 2009 in Arena Naucalpan, Naucalpan, State of Mexico, Mexico. As the name implies the show celebrated the 32nd Anniversary of the construction of Arena Naucalpan, IWRG's main venue in 1977. The show is IWRG's longest-running show, predating IWRG being founded in 1996 and is the fourth oldest, still held, annual show in professional wrestling. The show was also promoted under the name Prison Fatal ("Deadly Prison"), a name first used for the 2000 Prison Fatal show.

The main event of the show was a ten-man steel cage match fought under Lucha de Apuestas, or "bet match", rules where the last man in the cage would be forced to unmask or have their hair shaved off if they were unmasked. The steel cage match saw Exodia, Fantasma de la Ópera, El Hijo de Pirata Morgan, Péndulo, Tóxico, Trauma I, Ultramán Jr. and Xibalba all leave the cage. In the end, Zatura pinned Capitán Muerte, forcing Capitán Muerte to umask and reveal his real name, Guillermo Martinez Cid.
