José de Jesús Álvarez (born June 2, 1978) is a Mexican professional wrestler, better known by his ringname Joe Líder. He currently competes in Asistencia Asesoría y Administración. He is known for being a former member of the tag team La Hermandad Extrema with Nicho el Millonario who, like himself, is one of several wrestlers to emerge from the independent circuit during the 1990s. Álvarez is also the real-life brother of Demoledor and had faced him on several occasions during his career, most notably, defeating him in their hometown in a "hair vs. hair" match at the Arena Victoria in January 2005.

In one of his first matches with The Mexican Powers, he and Crazy Boy teamed with Juventud Guerrera and Psicosis II in an 8-man tag team match to defeat Chessman, Escoria, Cuervo and Ozz at the Verano de Escandalo (2006) on September 17, 2006. Three months later at Guerra de Titanes 2006, Líder was pinned by Escoria in a match with Crazy Boy and Psicosis against Escoria, Cuervo and Ozz.

He also took part in a 4-team elimination match to determine the first AAA World Tag Team Championship at Rey de Reyes (2007) but lost out to Cuervo and Ozz when Líder was pinned by Ozz in the final fall. The other participants were Alan Stone and Zumbido and Pegasso and Super Fly.

Crazy Boy (born March 30, 1978) is a Mexican professional wrestler who is best known in Lucha Libre. He currently works for Asistencia Asesoría y Administración in Mexico. Crazy Boy is the first cousin of Super Crazy.

Around the turn of the millennium, Crazy Boy worked extensively in Naucalpan, Mexico State, for the then recently created International Wrestling Revolution Group (IWRG). In IWRG he formed a "suicidal" trio with Star Boy and Súper Boy who all used a high flying, high risk wrestling style. Crazy Boy is an AAA midcard tecnico and a member of the Mexican Powers. He's a recent addition to AAA, having spent some time in the CMLL undercards. He's most known for his indy work in hardcore/extreme Mexican promotions.

Crazy Boy's stint in CMLL ended in a messy way, with Crazy pulling himself out from an Arena Mexico show (which would have been his first CMLL one there), claiming an injury from a just completed Japanese tour, only to show up as surprise in AAA days later.

He won the AAA promoted "Campeonato National de Atomico" (4 man tag team championship), along with Juventud Guerrera, Joe Lider and Psicosis II. After Psicosis II's betrayal costing the Meican Powers' their titles, Extreme Tiger was brought in as a replacement. Tiger has left the group since to join Halloween's new group, as it remains Crazy Boy, Joe Lider, and Juventud Guerrera. Along with Joe Lider and Juventud Guerrera, the group traveled to Japan to compete in Pro Wrestling Noah's TripleSEM, were they were victorious. Crazy Boy and Joe Lider thought still remain AAA World Tag Team Championship.

Gerardo Campos Poza (born March 28, 1978), better known under his ring name Último Gladiador (Spanish for "Last Gladiator") is a Mexican Luchador enmascarado, or masked professional wrestler. Poza currently works for the Mexican professional wrestling promotion Asistencia Asesoría y Administración as a part of the group La Maniarquía alongside Silver King and Chessman. Pozo has previously wrestled under the name El Potro as well as being the first wrestler to play the masked Mega character for International Wrestling Revolution Group.

Campos trained for his professional under Black Man and Rocky Santana as well as receiving additional training by his uncle Pantera later on. He made his debut on June 11, 1997 as a rúdo (bad guy) character called El Potro ("The Colt") teaming with Bombero Infernale and Sumo Fuji against the team of Magnum Tokyo, Fantasy and Niebelina on an International Wrestling Revolution Group (IWRG) show. After wrestling as El Potro for two months he became the enmascarado (masked) character Mega, part of a group called Los Megas that also included Ultra Mega and Super Mega. He wrestled as Mega for about a year, winning the hair of Judo Suwa as the highlight of his time as Mega. When he left IWRG the promotion gave the Mega character to Cesar Caballero.

Eduardo Aníbal González Hernández (born November 23, 1974 in Mexico City, D. F.), better known as Juventud Guerrera, is a Mexican professional wrestler who is best known for his work in many wrestling promotions worldwide, including all the major American wrestling promotions, such as World Wrestling Entertainment, World Championship Wrestling, Extreme Championship Wrestling and Total Nonstop Action Wrestling, as well as the major Mexican wrestling promotions Asistencia Asesoría y Administración and Consejo Mundial de Lucha Libre.

Early in his career Guerrera was a mainstay in the Asistencia Asesoría y Administración promotion. He had a very lengthy feud with Rey Mysterio, Jr. in which they traded the AAA Welterweight Title back and forth. The pair also had several tag team matches in which Guerrera would team with his father Fuerza, while Rey, Jr. would tag with uncle and trainer Rey Misterio, Sr.

Guerrera wrestled in many Mexican independent promotions as a masked wrestler but he first gained American exposure in Extreme Championship Wrestling alongside fellow luchadores Rey Misterio Jr., Psicosis, Konnan and La Parka, all of whom were also wrestling for Konnan's Promo Azteca in Mexico at the time. When Konnan left for WCW, Guerrera and the rest followed.

Teddy Annis (born February 2, 1980), is a Canadian professional wrestler, better known by his ring name Teddy Hart. He is currently working on the American independent circuit for promotions such as Jersey All Pro Wrestling and Dragon Gate USA. He has also wrestled for the Mexican promotion Asistencia Asesoría y Administración and the short-lived Wrestling Society X on MTV, and operates a wrestling school in Calgary.

Hart achieved a degree of fame when he became the youngest wrestler to be signed to the World Wrestling Federation. His subsequent release and controversial actions while wrestling on the independent circuit have earned him a measure of infamy.

Hart debuted in July 1995 at Rockyford, Alberta, where he teamed up with his brother, Matthew, for the first time, and defeated his cousin, Harry Smith, and TJ Wilson. In the Calgary-based Stampede Wrestling promotion, Hart teamed with Smith, Wilson and Jack Evans. In 2000, he wrestled for and was a key creative figure in the Matrats promotion.
