Juan Francisco Domínguez[1] (born September 8, 1977)[2] is a Mexican luchador, or professional wrestler, currently performing under the ring name X-Fly.
Domínguez made his professional wrestling debut for AAA in October 1995 as the masked Mosco de la Merced ("Mosquito of the Mercy").
[5] However, just two months later Domínguez left the promotion and the Mosco de la Merced character, and his Mexican National Tag Team Championship, were given to another performer.
Domínguez also made sporadic appearances for AAA in 2004 and 2007 as member of Los Kumbia Kids and La Hermandad Extrema, now working under the ring name X-Fly.
[10] X-Fly was quickly made into a member of Los Perros del Mal, the main stable in the promotion, led by Aguayo.
[25] On August 11, X-Fly and Eterno defeated Negro Navarro and Trauma I to win the IWRG Intercontinental Tag Team Championship.
[31] Under the banner of La Sociedad, X-Fly became one of the most featured members of Los Perros del Mal, alongside Aguayo, Damián 666 and Halloween.
[32][33] In the match X-Fly replaced original participant El Hijo del Perro Aguayo, who was sidelined with a knee injury.
The match took place in the main event of the evening and saw, X-Fly, Damián 666 and Halloween hand Los Psycho Circus their first ever loss, following outside interference from Aguayo.
On June 18 at Triplemanía XIX, X-Fly again replaced Aguayo and teamed with Damián 666 and Halloween to defeat Los Psycho Circus and become the first ever AAA World Trios Champions.
