Passage: The Prisión Fatal concept was originally unveiled on December 2, 2012 during IWRG's first ever Prisión Fatal event. The match concept involved a 15 foot tall steel cage surrounding the wrestling ring. The competitors, so far always four, would each be attached by the wrist to a long chain where the other end is attached to the cage. The object of the match is to reach the key to the lock that is hung from the cage. Once a wrestler has the key he is able to unlock himself and climb out of the cage, thus escaping the match. The last man left in the ring would be forced to unmask and reveal his real name if he is masked, or have his hair shaved totally off if he is unmasked, as per the Luchas de Apuestas traditions. For the match Rayo de Jalisco, Jr. and Cien Caras, Jr. both risk their mask on the outcome while Pirata Morgan and Máscara Año 2000, Jr. risk their hair. Of the four wrestlers involved Máscara Año 2000, Jr. has only lost one Apuestas match, which forced him to unmask, while Pirata Morgan has lost a number of Apuestas matches and thus been shaved bald on multiple occasions in his 30-plus year career. Cien Caras, Jr. and Máscara Año 2000, Jr. had at this point been teaming together since 2007, forming Los Capos Junior along with Hijo de Máscara Año 2000, with no storyline signs of tension or friction between the two before the match was announced. Rayo de Jalisco, Jr. had not worked for IWRG on a regular basis since 2006 and not worked for IWRG in the months leading up to the Prisión Fatal show, making his inclusion in the steel cage match a bit of a surprise. Rayo de Jalisco, Jr. had been involved in a long running storyline feud with Los Capos, including Máscara Año 2000, Jr.'s father Máscara Año 2000, the storyline father of Cien Caras, Jr., Cien Caras and Universo 2000, but that storyline had up until the time of the show being announced only sporadically involved the second generation Capos, primarily when Rayo de Jalisco, Jr. teamed up with his son Rayman to take on the senior/junior Máscara Año 2000s. Pirata Morgan and his sons had been a regular worker for IWRG for several years and had at times wrestled Los Capos Junior, but this had never escalated into a long running storyline feud. The first real interaction between the factions in the main event of the Prisión Fatal show happened on March 10, 2013 during the main event of an IWRG event where Cien Caras, Jr. and Máscara Año 2000, Jr. teamed up with Hijo de Máscara Año 2000 to take on the team of Hijo de Pirata Morgan, Pirata Morgan and Electroshock. During the match Cien Caras, Jr. used an illegal low blow on Hijo de Pirata Morgan to win the first fall for his team, taking advantage of the fact that all six competitors were in the ring at the same time, distracting the referee. During the second fall Pirata Morgan tried to gain a measure of revenge for his son and pulled Cien Caras, Jr.'s mask off, but this illegal move was noticed by the referee who disqualified his team for the overall loss. Following the match all six wrestlers fought both inside and outside of the ring until they were separated by officials.
