Humberto Sánchez Medorio is a Mexican luchador Enmascarado, or masked professional wrestler, better known by his ring name Pequeño Black Warrior, or Pequeño Warrior. Sánchez works for the Mexican professional wrestling promotion Consejo Mundial de Lucha Libre (CMLL), in their Mini-Estrella division as a smaller version of wrestler Black Warrior. Sánchez previously worked for Asistencia Asesoría y Administración (AAA) as Mini Psicosis, a smaller version of the wrestler Psicosis. Working in the Mini division does not necessarily mean that Sánchez has dwarfism as several short wrestlers work in the "Mini" division, which is what separates the Mexican Mini-Estrella from traditional Midget wrestling as practiced in the United States and other places.
