WCW Executive Vice-President Eric Bischoff had helped AAA secure the show to be broadcast by American pay-per-view providers, marking the first time a non-US-based wrestling promotion was shown live on US PPV television.

Chris Cruise and Mike Tenay called the action in English, while Arturo Rivera and Andrés Maroñas handled the Spanish announcing.

The event featured five professional wrestling matches with different wrestlers involved in pre-existing, scripted feuds, plots, and storylines.

El Hijo del Santo received backup in the form of Octagón, a very popular masked técnico who had starred in several Lucha Libre Films in the past.

The feud between the two teams would evolve into Barr and Guerrero recruiting other wrestlers, most importantly Konnan, who up until joining Los Gringos Locos was one of the most popular técnicos in Mexico.

[6] On July 23, 1994, La Pareja del Terror won the tag team titles, with the storyline being that the duo had paid off the referee to call the match in their favor.

[8] Konnan and Aguayo would face off several times over the following months, often as the captains in six-man tag team matches, most of which ended with inconclusive outcomes and both wrestlers hitting each other with chairs and other objects.

In the weeks prior to When Worlds Collide, the fans had begun to support La Parka, taking to his more comedic wrestling style and very distinctive skeleton body suit and mask, sowing the seeds for La Parka potentially turning to the tecnico side, but prior to this point he was still working the rudo side.

The Guerreras were also involved in a long-running storyline against the then-reigning Mexican National Tag Team Champions Heavy Metal and Latin Lover over the championship.

For unexplained reasons, Fuerza Guerrera and Psicosis were not teamed up with Juventud Guerrera for the show but instead were teamed with Gringo Loco member Madonna's Boyfriend for the match against Heavy Metal, Latin Lover, and Rey Misterio Jr.[1] The opening match was another chapter in a long-running storyline between two of AAA's top Mini-Estrellas, Mascarita Sagrada and Espectrito, a storyline that actually predated the creation of AAA in 1992.

Mascarita Sagrada defeated Espectrito in the tournament to determine the first-ever CMLL World Mini-Estrella Champion in what was one of the early highlights of their storyline feud.

[12] When Peña decided to break away from CMLL to create AAA, a large part of the Mini-Estrellas division left with him, including the champion Mascarita Sagrada and Espectrito, vacating the championship in the process.

[12] In AAA Peña got the Mexico City Boxing and Wrestling Commission to sanction the creation of the Mexican National Mini-Estrella Championship, a title that Espectrito won by defeating Mascarita Sagrada in the finals of a tournament.

[9][14] Prior to the start of the show, the producers from WCW/Turner Broadcasting System made several changes to the format, including reducing the overall time by 40 minutes.

In the third match of the night, "Pegasus Kid" Chris Benoit was the captain on the IWC team which also included 2 Cold Scorpio and Tito Santana.

Blue Panther was the captain of the AAA team, having the task of trying to keep the peace between his partners La Parka and Jerry Estrada, as they had not been getting along in the weeks leading up to the match.

Moments later, 2 Cold Scorpio dove off the top rope to the floor, knocking down La Parka, Estrada, and Santana with the move.

La Pareja del Terror tried to take control of the match early by attacking their opponents before the bell had even rung, but were quickly tossed out of the ring as the US crowd began to chant "Mexico".

Later in the match, Guerrero performed a Huracanrana with Hijo del Santo sitting on the top rope and gained a pinfall, leaving Octagón at a disadvantage in the second fall.

Moments later, the unsuspecting Barr was rolled up into Octagón's trademark submission hold La Escalera and was forced to submit, tying the match at one fall each.

Later in the fall, with the referee distracted, Barr was able to surprise Octagón and execute a kneeling reverse piledriver, a move that would have been an automatic disqualification in Lucha Libre.

In Lucha Libre, the piledriver is treated as a very dangerous move, something that was sold during this match by Octagón being taken from the arena on a stretcher during the closing moments of the third fall.

At one point, both Hijo del Santo and Guerrero were on the floor, which distracted the referee long enough for Blue Panther to enter the ring and perform a piledriver of his own on Barr in retaliation for what was done to Octagón.

As the cage lowered, Mike Tenay introduced the match and then handed the microphone over to AAA announcer Arturo Rivera to give the introductions in Spanish.

While at ringside, Guerrero got into a fistfight with several fans who were upset over his actions, forcing the security guards to step in and stop the fight.

A week after When Worlds Collide, Perro Aguayo followed up his steel cage win by winning the IWC World Heavyweight Championship from Konnan in a match that was originally designed to be part of the storyline in which Konnan turned tecnico after Los Gringos were unable to help him retain his title, but that aspect of the storyline was dropped a few weeks later.

[24] Konnan turned tecnico in the wake of Barr's death and teamed up again with Perro Aguayo, especially as they fought against Los Capos (brothers Cien Caras and Máscara Año 2000) in what would be the new main storyline in AAA leading to Triplemanía III.

El Hijo del Santo would work for AAA until mid-1995 and then leave the promotion due to disagreements over pay and position on the shows, jumping to rival CMLL in the process.

[32] The La Pareja del Terror tag team match was featured on the "Eddie Guerrero, Cheating death, stealing life" DVD released in 2004.

As part of the settlement, WCW agreed to supply three of its contracted wrestlers for an ECW event on November 18, 1994: Kevin Sullivan, Sherri Martel, and Steve Austin (later replaced by Brian Pillman).
