Antonio Sánchez Rendón (born September 4, 1954 — June 6, 2024)[1] was a Mexican luchador, or professional wrestler, best known under the ring name El Signo (Spanish for "The Symbol").
He was born on September 4, 1954, in Ocotlán de Morelos, Oaxaca, Mexico, and trained for his professional wrestling career under Billy Robinson, Chamaco Azteca and El Carnicero.
He began wrestling as the enmascarado character "El Signo" ("The Sign"), wearing a mask (most often black) with an upside down question mark on the front of it.
promoter Francisco Flores wanted to develop his own group of smaller, faster wrestlers into top level competitors and came up with the idea to team El Signo up with two similar sized wrestlers Miguel Calderón Navarro, known as Negro Navarro and Juan Conrado Aguilar Jáuregui, who was working under the name El Texano, forming a trie known as Los Misioneros de la Muerte ("The Missionaries of Death").
During the main event Los Misioneros faced off against then 64-year-old El Santo, who was teaming up with Huracán Ramírez and Rayo de Jalisco.
During the match El Santo collapsed in the middle of the ring, suffering a heart attack after a hard blow to the chest.
Negro Navarro won the UWA World Junior Heavyweight Championship from Shu El Guerrero on December 27, 1993, and would hold that title until the promotion closed in 1995.
[11] The trio held on to the Trios Championship for 454 days, until May 1, 1993, where they lost them to El Engendro, Shu El Guerrero and Scorpio, Jr., they regained the championship later that year, on December 25 and held them into 1994 where they lost the belts back to Engendro, Shu el Guerrero and Scorpio, Jr.[12] Black Power was later replaced by Rocky Santana and that version of Los Misioneros did win the UWA World Trios Championship on two occasions, holding the distinction of being the last team to hold the titles before the UWA closed in 1995.
[15] After the closure of the UWA in 1995 Negro Navarro and El Signo split up, going their separate ways on the Independent circuit, only teaming together for special occasions.
El Signo teamed up with Blue Panther and Fuerza Guerrera, two wrestlers with a similar background and age to compete in the tournament for the titles.
[16] During his time in CMLL he had an occasion to team up with Negro Navarro again, for the Salvador Lutteroth Memorial Tag Tournament held as part of Consejo Mundial de Lucha Libre (CMLL; formerly known as EMLL)'s 1999 Homenaje a Dos Leyendas: El Santo y Salvador Lutteroth show on March 19, 1999.
Navarro and El Signo teamed up to represent the "old school" wrestlers of Lutteroth's era and defeated Olímpico and Tony Rivera in the first round of the tournament.
[17] El Signo stopped working full-time for CMLL in 1999 or 2000, despite still being part of the Mexican National Trios Championship team, leaving the title to be mainly inactive and not highly promoted.
