César Cuauhtémoc González Barrón (9 January 1968 – 11 May 2019) was a Mexican luchador enmascarado (masked wrestler) and actor. He was known best as Silver King, but also had an extensive stint as the third wrestler to portray the Black Tiger character. He was the son of luchador Dr. Wagner and the brother of Dr. Wagner Jr. González worked for many years with El Texano as the tag team "Los Cowboys," winning tag team championships in both Mexico and Japan. González worked for the Universal Wrestling Association (UWA), Consejo Mundial de Lucha Libre (CMLL), Lucha Libre AAA World Wide (AAA), World Championship Wrestling (WCW), All Japan Pro Wrestling (AJPW), New Japan Pro-Wrestling (NJPW) and various smaller federations all over the world. González also starred as the villain "Ramses" in the movie Nacho Libre, starring Jack Black. In June 2010, González began using the ring name Silver Cain/Silver Kain when wrestling in Mexico City as a way to be able to officially be allowed to wear his mask again. In 2019, he was posthumously inducted into the AAA Hall of Fame.
