Stuka Jr. is a Mexican luchador enmascarado, or masked professional wrestler, who works for the Mexican professional wrestling promotion Consejo Mundial de Lucha Libre (CMLL). Stuka Jr. is not, despite what the name indicates, the son of Luchador Stuka but his much younger brother. Stuka Jr. regularly teams with Fuego, with whom he held the CMLL Arena Coliseo Tag Team Championship for a record four and a half years. Stuka Jr.'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.
