Pequeño Nitro is a Mexican luchador enmascarado, or masked professional wrestler, working for the Mexican professional wrestling promotion Consejo Mundial de Lucha Libre (CMLL) in their Mini-Estrella division. This does not necessarily mean that Pequeño Nitro is a dwarf as several wrestlers who are just shorter in stature work in the "Mini" division. Pequeño Nitro'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. His name means "Little Nitro" and his ring character is based on Nitro, a regular-sized luchador.
