Starting in 1997 the Mexican professional wrestling, company AAA has held a major wrestling show late in the year, either November or December, called Guerra de Titanes. The show often features championship matches or Lucha de Apuestas or bet matches where the competitors risked their wrestling mask or hair on the outcome of the match. In Lucha Libre the Lucha de Apuetas match is considered more prestigious than a championship match and a lot of the major shows feature one or more Apuesta matches. The Guerra de Titanes show is hosted by a new location each year, emanating from cities such as Madero, Chihuahua, Chihuahua, Mexico City, Guadalajara, Jalisco and more. In 2016 AAA moved the Guerra de Titanes show to January, with the 2017 version continuing that trend.
Storylines
The Guerra de Titanes show featured six professional wrestling matches with different wrestlers involved in pre-existing, scripted feuds, plots, and storylines. Wrestlers were viewed as either heels or faces as they followed a series of tension-building events, which culminated in a wrestling match or series of matches. At Triplemanía XXIV, AAA's biggest show of the year, Psycho Clown defeated Pagano in the main event Lucha de Apuestas, or "bet match". During the closing moments of the match Dr. Wagner Jr. came to the ring, initially looking like he was trying to help Psycho Clown, but turned on him instead. After the match was over Dr. Wagner Jr. challenged Psycho Clown to put his mask on the line at Triplemanía XXV the following year. At AAA's next major show, Héroes Inmortales X, Dr. Wagner Jr, Psycho Clown and Pagan faced off in a triple threat match. During the match Psycho Clown's long time tag team partners Murder Clown and Monster Clown joined sides with Dr. Wagner Jr., attacking Psycho Clown so Dr. Wagner Jr. could win the match. For Guerra de Titanes AAA originally announced that Dr. Wagner Jr., Pagano and El Mesías would wrestle the trio of Psycho Clown, La Parka, and El Texano Jr. in the main event. On July 3, 2016 Pentagón Jr. defeated Psycho Clown to win the AAA Latin American Championship. The following week the team of Johnny Mundo, El Mesias and Hernandez, collectively referred to as "Team Trump", defeated the trio of Pentagón Jr., El Texano Jr. and El Hijo del Fantasma when Mundo pinned Pentagón Jr. Following the match Mundo challenged Pentagón Jr. to defend the Latin American championship against Mundo since he just pinned the champion. At Triplemanía XXIV Mundo won the AAA Latin American Championship from Pentagón Jr., furthering the storyline of Mundo, along with the rest of "Team Trump", claiming that the United States was much better than Mexico. At Héroes Inmortales X Mundo defeated Garza Jr., following a challenge by Pentagón Jr. for a rematch at the 2017 Guerrera de Titanes, a challenge that was later accepted.
Aftermath
The night after the show at a show promoted by The Crash in Tijuana, Baja California, Pentagón Jr., Daga and Garza Jr. made a surprise appearance during the show, alongside Pentagón Jr.'s brother Fénix el Rey. The trio announced that they had left AAA effective immediately. At the same time Pentagón Jr. announced that he would be known as "Penta El 0M" since AAA owned the rights to the name Pentagón Jr. All three wrestlers cited their unhappiness with AAA and the lack of opportunities they were given. It was later revealed that none of the wrestlers had told AAA they were leaving, which meant that both Pentagón Jr. and Garza Jr.'s championship losses were the planned finishes. When asked for a reaction to the three wrestlers leaving AAA officials simply stated that those that remained with AAA were happy to be there, not commenting further on the situation.
