Nygma has been a member of Los Vatos Locos, a Kiss look-alike group of wrestlers, with whom he held the Mexican National Atómicos Championship.
Nygma'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.
[1] The wrestler who later became known as Nygma made his debut in 1992 under the ring name Galaxi after training under Rodolfo Ruiz, Raúl Reyes and Bestia Negra.
[2] In mid-1998 AAA owner Antonio Peña put together a new group of wrestlers, a stable called Los Vatos Locos (Spanish for "the crazy guys") consisting of Nygma, Charly Manson, May Flowers and Picudo.
After joining Los Vatos Locos Nygma changed his appearance slightly, adopting an outfit and a face paint/mask combo inspired by Kiss lead guitarist Ace Frehley's "Spaceman" look.
In keeping with the "Kiss" theme set by Nygma and Picudo, Espiritu altered his appearance to look more like Paul Stanley's "Starchild" character.
At the 2007 Antonio Peña Memorial Show Nygma returned to action, siding with Exóticos Polvo de Estrellas, Jessy and Yuriko, forming a group called Los Night Queens.
[12] After fourteen months away from AAA, Nygma returned on October 31, 2010, forming a new version of Los Bizarros with Cibernético, Amadeus, Escoria and Taboo.
