Arturo Díaz Mendoza was a Mexican professional wrestler who performed under the ring name Villano III. Díaz was a second-generation wrestler, son of luchador Ray Mendoza and the father of professional wrestlers Villano III Jr. and El Hijo del Villano III himself. All five of the Díaz brothers used the Villano name; José de Jesús, José Alfredo, Tomás and Raymundo. Of the five Villanos, Arturo was considered the most successful in terms of championship and Lucha de Apuesta wins as well as the most talented luchador in the family. He retired from wrestling in 2015 due to health issues stemming from wrestling. A few days after his death, he was inducted in the AAA Hall of Fame.

A wrestling mask is a fabric-based mask that some professional wrestlers wear as part of their in-ring persona or gimmick. Professional wrestlers have been using masks as far back as 1915 and they are still widely used today, especially in Lucha Libre in Mexico.
