Fuego is a Mexican luchador enmascarado, or masked professional wrestler currently working for the Mexican professional wrestling promotion Consejo Mundial de Lucha Libre (CMLL). His original ring character, Flash, was inspired by the comic book character The Flash. Fuego regularly teams with Stuka, Jr., with whom he held the CMLL Arena Coliseo Tag Team Championship for a record four and a half years. Fuego'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. On November 19, 2009, it was announced that Flash was changing his ring name to Fuego from that point forward.

Omar Alvarado García, better known by his ring name Stuka Jr., is a Mexican luchador, who works for the Mexican professional wrestling promotion Consejo Mundial de Lucha Libre (CMLL), where he is a member of the Los Guerreros Laguneros stable. Stuka Jr. is not, despite what the name indicates, the son of luchador Stuka, but is actually Stuka's younger brother.
