Octavio López Arreola (born April 12, 1975) is a Mexican professional wrestler who is best known under the ring name Cibernético, currently working for the Asistencia Asesoría y Administración (AAA) promotion in Mexico. During AAA's short partnership with the World Wrestling Federation, he participated in the 1997 Royal Rumble and wrestled on Raw is War and WWF Shotgun, often teaming with Pierroth, Jr. He is a former AAA World Heavyweight Champion as well as a former three time Campeón de Campeones, the predecessor to the AAA world championship.

Octavio López started out as a body builder, developing the physique that would later on become one of his strong points. He began training for a professional wrestling career in the Universal Wrestling Association (UWA) Gym under Karloff Lagarde and Ray Mendoza as well as training with Ojo de Tigre and Ebano Ruiz. He made his professional wrestling debut in 1992 under the ring name Urko and later worked as Espiritu Negro for a brief period of time. After wrestling for a few months he decided to dedicate himself to developing his physique and receive further training in the UWA wrestling school. In June, 1994 he made his re-debut for the UWA, this time working under a new ring character, Cibernético, or Cyborg, complete with a colorful mask that looked like it had printed circuitry on it to enhance the "Cyborg" character. On July 31, 1994 Cibernétcio wrestled on his first Torero de Cuatro Camnios show, UWA's biggest venue. On the night he teamed up with veterans El Canek and Dos Caras, taking on Los Villanos, Villaño III, Villaño IV and Villaño V. While he made his debut as a tecnico (fan favorite) he soon turned against El Canek, turning rudo (villain), setting up a feud with the UWA's top tecnico in the hopes of using Cibernético to replace some of the UWA headliners that had left the promotion. The attempt to create new headliners was too late and by January 1995 the UWA closed down.

Pedro Aguayo Ramírez (born July 23, 1979) is a Mexican professional wrestler and promoter who achieved fame in lucha libre as Perro Aguayo, Jr. or El Hijo del Perro Aguayo ("The Son of Perro Aguayo"). He is legitimately the son of lucha libre legend Perro Aguayo and not a storyline "Junior". Aguayo is best known as the leader of the Perros del Mal stable, which he started in Consejo Mundial de Lucha Libre (CMLL) in the summer of 2004. The stable became a significant draw in Mexican professional wrestling, peaking during Aguayo's storyline rivalries with Místico and Héctor Garza. In October 2008, Aguayo left CMLL to start his own independent professional wrestling promotion Perros del Mal Producciones, built around members of his Los Perros del Mal stable. In June 2010, Aguayo returned to Asistencia Asesoría y Administración (AAA) after a seven year absence to start an invasion storyline involving his stable.

Pedro Aguayo (born January 18, 1946) better known as "Perro Aguayo" (Dog Aguayo) and El Can de Nochistlan (Nochistlan Dog), was a famous Mexican wrestler through 1970s to 1990s. His son also wrestles as Perro Aguayo, Jr. or El Hijo del Perro Aguayo ("The Son of Perro Aguayo"). He is one of the biggest box office attractions in lucha libre history and was the last major rival of El Santo. Often prone to blading, Aguayo has been described by American pundits as a cross between Terry Funk and Bruno Sammartino (for his willingness to brawl and overpower opponents). He was the first person ever crowned the WWF Light Heavyweight Champion, though pre-1997 title reigns are not included in WWE's official "canon" for that title.

Aguayo was synonymous with the Universal Wrestling Association as one of its top heels and one of the top heels lucha libre overall. In the 1990s, Aguayo helped found Asistencia Asesoría y Administración and his three way feud with Konnan and Cien Caras proved to be one of the most successful programs in terms of box office receipts. He stayed with AAA until 2000, even making an appearance on WWF's Royal Rumble in 1997 in a match that featured lucha libre legends like El Canek, Mil Máscaras and up and comers who would later make names for themselves like Héctor Garza and Heavy Metal. He came to Consejo Mundial de Lucha Libre to feud with Los Capos. He was successful in taking the hair of Cien Caras and Máscara Año 2000 but he lost his slated retirement match against Universo 2000. He remained in retirement until his son began feuding with Los Capos as well. Cien Caras claimed he could not retire until his business with Aguayo was finished so a double hair vs. hair match was set with Perro Aguayo and Perro Aguayo taking on Cien Caras and Máscara Año 2000. The Aguayos were successful and Perro Aguayo returned to retirement and Cien Caras went into semi-retirement.

Within a month of his debut Konan Big had already won the mask of "Latin Heart" when he defated him in a Luchas de Apuesta (bet match). On February 22, 2004 Konan Big lost his own mask when he was defeated in an Apuesta match by Spiderman. Not long after his unmasking Konan Big became involved in a storyline feud with Football player Patricio "Pato" Zambrano, the storyline was that television actress Irma Serrano hired Konan Big to humiliate Pato Zambrano by shaving his hair off. The plan backfired as Pato Zambrano defeated Konan Big in a Luchas de Apuesta match on August 1, 2004. In the following years Konan Big would wrestle against other local celebrities such as male model Alfonso de Nigris, Regalito the Clown, and football commentator Mario Bezares.
