After training under Diablo Velasco and Pantera Negra, Reyes debuted in 1974 under the ring name "Mil Caras", but due to the obvious confusion with
Mil Máscaras, he dropped 900 units to become "Cien Caras". Caras was initially a
técnico, but quickly developed a more violent wrestling style, and became a
rudo. On June 24, 1987, in
Nezahualcóyotl,
State of Mexico, Caras defeated
MS-1 for the
NWA World Light Heavyweight Championship. He held the title until March 20, 1988, when he lost to Lizmark in
Mexico City,
Mexican Federal District. On September 21, 1990, he lost his
mask in the
culmination of a
feud with
Rayo de Jalisco, Jr. In late 1990, Caras was wrestling against Jalisco Jr. in a
steel cage match when a fan threw a peso coin that hit Caras in the eye. He missed over a month due to the eye injury, and there was concern at the time that his career might be over. On August 18, 1991, in
Monterrey, Caras defeated
Konnan el Barbaro to become the second ever
CMLL World Heavyweight Champion. He held the title until leaving the CMLL in May 1992, vacating the title in the process. Caras followed Konnan to the newly formed
Asistencia Asesoría y Administración, where he continued his feud with Konnan. At the inaugural TripleMania event on April 30, 1993, Caras defeated Konnan in a
two out of three falls retirement match by count-out after
Jake "The Snake" Roberts interfered on his behalf. Caras remained in the AAA for several years before returning to the CMLL. In one of his last matches in the promotion, he teamed with
Heavy Metal and
Latin Lover in a championship tournament to crown the first
AAA Americas Trios Championship and lost to Los Villanos (
Villano III,
IV and
V) at the tournament finals in
Ciudad Nezahualcoyotl on March 8, 1996. In CMLL, Caras is a member of the
stable Los Capos ("The Bosses") with his two younger brothers,
Máscara Año 2000 and
Universo 2000 (
Los Hermanos Dinamita—"The Dynamite Brothers"), and Apolo Dantes. In 2004, Caras and Mascara Año 2000 were defeated by
Perro Aguayo, Jr. and
El Terrible in a hair versus hair tag team match at the annual
Homenaje a Dos Leyendas: El Santo y Salvador Lutteroth show with Caras and Mascara having their heads shaved as a result. Caras and Mascara fought Aguayo, Jr. and his father,
Perro Aguayo, in a second hair versus hair match in February 2005, with Caras and Mascara losing once again. The match was billed as Caras's retirement match, but he continued to wrestle in secondary CMLL venues, making him semi-retired. ==Championships and accomplishments==
