Reyes was forced to unmask when he lost a Lucha de Apuesta (bet match) to Perro Aguayo in 1993.

On 16 April 1986 Máscara Año 2000 and Cien Caras defeated Rayo de Jalisco and Tony Benetto to win the Mexican National Tag Team Championship.

[6] Universo 2000 was originally chosen to be the wrestler to unmask the legendary Aníbal, who had returned for the big payday a mask loss is.

[8] In mid-1992 then CMLL booker Antonio Peña decided to break away from the promotion and form his own promotion called Asistencia Asesoría y Administración, wanting to produce his own style of wrestling shows that differed from the very conservative way CMLL ran things.

[8] Máscara Año 2000 had begun a feud with Perro Aguayo while both still worked for CMLL and the storyline tension between the two continued as they both jumped to AAA.

The two faced off in the semi-main event of the first-ever Triplemanía in a Lucha de Apuesta, mask vs. hair match.

[11] One of Universo 2000's last matches in AAA took place at Triplemanía III-C where Los Hermanos Dinamita teamed up with Jerry Estrada and Fishman to defeat Konnan, La Parka, Máscara Sagrada, Latin Lover and Perro Aguayo.

[13] Máscara Año 2000 remained with CMLL until some point in 2007 or 2008 where he left the promotion and began working on the independent circuit.

Cien Caras' biological children, Sanson and Cuatrero, also wrestle in CMLL with their cousin Forastero (son of the Dinamitas' sister).
