ByMike ReichlinProfessional Wrestling Journalist

Thematic Overview

Match Previews

AAA Mega Championship: Dominik Mysterio (c) vs. El Grande Americano

AAA’s top title closes the show, with the champion’s own booking history hanging over the match.

  • The reign: Dominik Mysterio enters as the reigning AAA Mega Champion.
  • The contract signing: At Ola de Calor, Dominik tried to use the signing to pressure Rey Mysterio into lifting Omos’ suspension, only agreeing to sign after Rey threatened to strip him of the title.
  • The challenger’s stance: El Grande Americano told Rey he didn’t want to win the title through Dominik being stripped, insisting on earning the shot in the ring.
  • The family layer: Rey Mysterio, Dominik’s father, is the AAA general manager who booked this match and nearly blew it up before it was signed.
  • What’s at stake: The match closes a two-night event that already saw Rey Mysterio wrestle his own high-stakes match in Las Vegas two days earlier.

AAA Reina de Reinas Championship: Flammer (c) vs. La Catalina

La Catalina gets a childhood dream shot at Flammer’s title.

  • The challenge: La Catalina said she has wanted the Reina de Reinas Championship since she was a child in Chile.
  • The needle: Catalina questioned whether Flammer could beat her without help from Las Toxicas.
  • What’s at stake: This is separate from the Night 1 four-way that determines a different Reina de Reinas challenger for Worlds Collide, meaning the title could change hands in Mexico City before that match is even contested.

AAA World Cruiserweight Championship, Fatal 4-Way

Rey Fenix defends against three men after a title match kept multiplying.

  • The qualifier: Jack Cartwheel, Mini Vikingo and Nathan Frazer wrestled to a time-limit draw at Ola de Calor in a match meant to produce one challenger.
  • The response: Rather than run it back, Fenix came out and offered a title shot to all three men at once.
  • The double duty: Frazer wrestles in Las Vegas on Night 1 as part of Fraxiom before arriving in Mexico City for this title shot.
  • What’s at stake: Fenix defends against a three-man field with legitimate in-ring claims rather than a single hand-picked opponent.

AAA World Tag Team Championship, Open Challenge: War Raiders (c) vs. TBA

Erik and Ivar are betting on themselves with a title defense against an unnamed opponent.

  • The announcement: Asked about their TripleMania plans during a backstage interview, the War Raiders issued an open challenge for the titles rather than naming a specific rival.
  • The scheduling wrinkle: The champions are also defending against Damian Priest and R-Truth on the September 11 episode of WWE SmackDown from Mexico City, the same day as TripleMania Night 1 in Las Vegas.
  • What’s at stake: The open challenge format means the opponent stays unknown until Night 2 itself.

Mexican Street Fight: Psycho Clown vs. El Carnicero

A mystery attacker gets his receipt turned into a weapons-legal brawl.

  • The origin: An unknown masked luchador attacked Psycho Clown during an August 8 Latin American Championship tournament match, costing him the bout. That attacker was later revealed as El Carnicero.
  • The debut: El Carnicero’s in-ring debut at Ola de Calor ended in a no-contest when he refused to stop choking his opponent.
  • The receipt: Psycho Clown ran in with a kendo stick to clear Carnicero out, then challenged him to a Mexican Street Fight at TripleMania.

How to Watch
