José Alfredo Díaz Mendoza (September 25, 1949 – April 17, 1989) was a Mexican Luchador enmascarado (masked professional wrestler), better known by his ring name, Villano II (Villano Segundo). Despite being numbered "II" he was the oldest of the Díaz Mendoza boys. His younger brothers wrestled or wrestle as Villano I (José de Jesús), Villano III (Arturo), Villano V (Raymundo), and Villano IV (Thomas). He is the son of Luchador Ray Mendoza. Villano II has at times been called "the Forgotten Villano" as he is the Villano who achieved the least success in the ring and only wrestled a sporadic schedule for the latter part of his career.
José Alfredo Díaz Mendoza, called Alfredo for short, was the oldest son of luchador Ray Mendoza and grew up watching his father compete as a very successful Light Heavyweight. When he and his one-year younger brother José de Jesús were old enough they began training to be wrestlers themselves. Mendoza insisted that both brothers should get a college education to fall back on in case wrestling failed. As Rey Mendoza was still very much in demand all over Mexico, and as a result travelled a lot, Bobby Bonales completed most of the Díaz' training. Both Alfredo and José de Jesús made their professional wrestling debut in 1969, reportedly with their father initially unaware, and began working as a tag team known as "Los Bestia Negras" ("The Black Beasts"), with José de Jesús working as Bestia Negra I and Alfredo as Bestia Negra II, even though he was older. Later on the team worked as Los Búfalo Salvaje ("The Wild Buffalos") again with José de Jesús as "I" and Alfredo as "II". In 1970 the brothers came up with new ring characters, "Los Villanos" ("The Villains"), and the name, along with a very distinctive "X" designed mask, stuck with them for the rest of their careers.
Once he comes to you With a friendly smile
Promises joy and everything you want
He is going to try to win your confidence
All you have to do to sail through the clouds Is to try
He will say to you Feel yourself great and strong
Say no to all temptations no no no
What a felony - Hear the warning of your mind
What a felony It's the last help of this kind
If you take these drugs There's no way to return
The addiction begins You feel the awful pain
All kind of drugs Will never be a key
To open the gate To a better world
What a felony You think it's the easiest way you know
What a felony The addiction is something you can't control
What a felony - you'll fight against the time
What a felony You can't control your mind
