Gran Guerrero is a Mexican luchador enmascarado (or masked professional wrestler), who works for Consejo Mundial de Lucha Libre (CMLL), where he is the current CMLL World Heavyweight Champion, in his first reign. He portrays a rudo ("bad guy") wrestling character. He was originally introduced to the wrestling world under the ring name Último Guerrero Jr. in 2009 as the storyline son of Último Guerrero, and later made his wrestling debut under the name Taurus. In 2013 he was given a new image, re-introduced under the ring name "Gran Guerrero", officially acknowledging that he was the much younger brother of Último Guerrero. Gran Guerrero'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.
