Miguel Ángel Lugo made his professional wrestling debut on September 16, 2006, working as an enmascarado, or masked wrestler under the ring name "Eterno" (Spanish for "Eternal").
In July, 2008 Eterno and Lobo Metálico lost a Luchas de Apuestas, or "bet match" to El Forastero and Estigma and thus were forced to permanently unmask.
The feud between the two led to a number of well-received matches that would give both Eterno and Daga the opportunity to work for larger wrestling promotions in Mexico.
By 2010 Eterno began working for International Wrestling Revolution Group (IWRG) out of Naucalpan where he competed primarily as a rudo, playing the part of the bad guy.
[2] While working in IWRG he also trained in the IWRG training school under Negro Navarro and Black Terry and participated in IWRG's Torneo Futuro Idolos de Lucha Libre (FILL) tournaments, including one on November 16, 2010 that he won by outlasting 17 other wrestlers in a torneo cibernetico, elimination match that also included Alan Extreme, Bugambilia, Centvrión, Comando Negro, Dinamic Black, Extremo Boy, Golden Bull, Guardian de la Noche, Guerrero 2000, Keshin Black, Maligno, Menfis, Oass, Rayden, Rayito Mendoza, Saruman and Shark Boy.
[4] In 2010 Eterno began working regularly for Desastre Total Ultraviolento (DTU) as well as IWRG, and even formed a group called Los Mazisos that also included Ciclope, Arana de Plata, Pequeno Cobra, Loco Max, Terremoto Negro and La Mazisa.
[21] Following the championship losses Eterno would be involved in a storyline between the IWRG trainees and Fuerza Guerrera's Gimnasio Konkreto training school.
During the Arena Naucalpan 35th Anniversary Show Gimnasio Konkreto defeated the "IWRG Gym" team of Alan Extreme, Centvrión, Dinamic Black, Eita, Eterno, Imposible, Saruman and Violencia, Jr. in an elimination match.
On August 11, Eterno and X-Fly defeated Negro Navarro and Trauma I to win the IWRG Intercontinental Tag Team Championship.
