Pegasso's real name is not a matter of public record, as is often the case with masked wrestlers in Mexico where their private lives are kept a secret from the wrestling fans.
[3] In 2000 he began working for Asistencia Asesoría y Administración (AAA), one of Mexico's largest promotions, and was given a new ring persona named Pegasso, after the mythological horse.
[2] Pegasso wrestled on his first major show not long after signing on with AAA as he teamed with Oscar Sevilla, Path Finder and Ludxor to defeat Gran Apache, Angel Mortal, Marabunta and Mr. Condor on the undercard of the 2000 Verano de Escandalo pay-per-view event.
On April 7, 2009, Pegasso was one of 10 men competing for the vacant CMLL World Super Lightweight Championship but he was eliminated halfway through the match with the title going to Mascara Dorada instead.
He competed against Akuma, Blue Panther Jr., Cancerbero, Canelo Casas, Delta, Disturbio, Esfinge, Flyer, El Gallo, Guerrero Maya Jr., Joker, Raziel, Sagrado, Stigma and Boby Zavala.
[13][14] On December 25, 2015, as part of CMLL's annual Infierno en el Ring show Pegasso was one of twelve men risking their mask in the main event steel cage match.
