The Mexican professional wrestling promotion International Wrestling Revolution Group (IWRG; Sometimes referred to as Grupo Internacional Revolución in Mexico) produced and scripted a La Ruleta de la Muerte Máscaras (Spanish for "Roulette of Death of masks") tournament on December 22, 2018. The show took place in Arena Naucalpan, in Naucalpan, State of Mexico, Mexico, IWRG's main venue and the site of the majority of all their major shows and tournaments, and also served as the celebration of the 42nd anniversary of Arena Naucalpan.
For the event IWRG booked representatives of several wrestling schools for a special tag team tournament where the main trainer from the school teamed up with one of their students. The losing team of the tournament would see the student be forced to unmask per the tournament stipulation. In the end Gym Zeus trainer Oficial 911 and trainee Ketzal defeated Gym Warrior trainer Warrior Jr. and Gato Negro. As a result Gato Negro unmasked and revealed his real name. Other schools represented were: Gym FILL (trainer Negro Navarro and Puma de Oro), Gym Zaetas (trainer Freelance and Neza Kid Jr.), Gym Mexa (trainer Toro Negro and Torito Negro) and Gym Argentia (trainer Dragón Fly and Guerrero Olímpico). On the undercard Güero Tijuana was shaved bald as a result of losing a six-way Lucha de Apuestas, bet match, to Chicanito (winner), Baby Star, Canibal Jr., Poético, and Chef Benito. The show included five other matches.
