Triplemanía II-B was a major lucha libre, or professional wrestling event Asistencia Asesoría y Administración (AAA) that took place at Auditorio Benito Juárez in Zapopan, Jalisco on May 15, 1994. The show was the second of three Triplemanía II shows held in 1994, preceded by Triplemanía II-A, with a subsequent show held in 12 days later. 1994 was the first year AAA held multiple Triplemanía shows in a year, a tradition they would continue through 1997, after which Triplemanía became a single annual event. The annual Triplemanía show(s) are AAA's biggest show of the year, serving as the culmination of major storylines and feature wrestlers from all over the world competing in what has been described as AAA's version of WrestleMania or their Super Bowl event.^[2]

The Main event featured a Six-man "Lucha Libre rules" tag team match between the teams of Konnan, Perro Aguayo, and Cien Caras and the Los Gringos Locos team of Jake Roberts, Love Machine, and Miguel Pérez Jr. The semi-main event featured a best two-out-of-three falls Lucha de Apuestas, or bet match where both Máscara Sagrada and Black Cat put their mask on the line in the match. The show featured Japanese wrestlers Jushin Thunder Liger and Tiger Mask III on loan from New Japan Pro-Wrestling (NJPW). The fifth match of the night featured wrestlers who had worked primarily for the Universal Wrestling Association (UWA) until that point, Shu el Guerrero, Scorpio, Jr., and Gran Hamada, fighting AAA representatives Los Payasos ("The Clowns"; Coco Rojo, Coco Verde and Coco Amarillo)

The show was a direct build to Triplemanía II-C held only 12 days later in Tijuana, Baja California. Triplemanía II-C saw Konnan finally gain revenge on Jake Roberts as he defeated Roberts in two straight falls to force him to be shaved bald after the match. Most of AAA's roster, both tecnicos and rudos, came to the ring after the match to show their unity and to ensure Roberts had his hair shaved off. Roberts would remain with AAA for several months after the show but was not involved in any major storylines after the loss to Konnan. The Los Gringos Locos storyline carried AAA into their subsequent major shows "Night of Champions" and later on their first ever pay-per-view (PPV) AAA When Worlds Collide that was driven by the feud between a Pareja del Terror (Eddy Guerrero and Love Machine) facing off against El Hijo del Santo and Octagón in a Luchas de Apuestas match where Guerrero and Love Machine ended up losing their hair.^[6] 19 days afterwards Love Machine, real name Art Barr, dies of unknown causes.^[7] The popularity of Konnan in the wake of his victory over Jake Robers made his turn to the rudo side months later ever more shocking, with Konnan attacking his longtime friend Perro Aguayo during a match and joining Los Gringos Locos instead.^[8] At "When Worlds Collide" Aguayo defeated Konnan in a steel cage match.^[6]

A few days after the show the then-Mexican National Middleweight Champion was involved in a car accident where he injured his hand. Due to the injury the local boxing and wrestling commission could not give him medical clearance to wrestle against Blue Panther at Triplemanía II-C, causing him to forfeit the championship to Blue Panther.^[9][10]

John Molinario, who writes about wrestling for the Canadian Online Explorer, described the show as "possibly the best TripleMania show ever." and stated that it was "from top to bottom a sensational show".^[4] Wrestling Observer Newsletter founder and editor Dave Meltzer commented that the "show was awesome. It was among the greatest shows I probably ever saw" after witnessing the show live and in person.^[4] Meltzer rated the "Atómicos" tag team match at four-and-a-half star, the lucha de apuestas match at four-and-three-quarters stars, while giving the main event six-man tag team match four stars.^[11]
