La Peste Negra (Spanish for "The Black Plague") is a Mexican lucha libre, or professional wrestling, rudo, or villain, group also known as a stable that works for Consejo Mundial de Lucha Libre (CMLL). The core of the group is the Casas wrestling family, which includes members Negro Casas, El Felino and Prinsesa Blanca as well as former member Heavy Metal. The group is rounded out by Mr. Niebla and works a more comedic style, including black face paint, oversized afro wigs and dancing during their entrance. The group was founded in July 2008 when Mr. Niebla returned to CMLL after working for Asistencia Asesoría y Administración (AAA) and has consistently been used at the main event and semi-main event level in CMLL. Their motto is "be heinous and stinky"
