El Felino

Jorge Luis Casas Ruiz (born March 22, 1964), better known by his ring name El Felino ("The Feline"), is a Mexican luchador (or professional wrestler) working for Mexican wrestling promotion Consejo Mundial de Lucha Libre (CMLL). Casas started his professional wrestling career under the name Babe Casas, working for the Universal Wrestling Association (UWA). In 1989, he adopted the "Felino" ring character, wearing an orange full body suit and cat inspired mask. With the exception of a short stint in AAA in 1999, Casas has worked for CMLL since adopting the "El Felino" ring character. El Felino was originally an enmascarado, or masked professional wrestler, but was forced to unmask in March 2010 due to losing a match.

He is a second-generation professional wrestler, as he is the son of wrestler-turned-referee Pepe Casas and a part of the Casas wrestling family. His siblings include his older brother Negro Casas and younger brother Heavy Metal. He is also the uncle of wrestlers Canelo Casas, Danny Casas, Black Star, Destroyer and Nanyzh Rock. His sons are both wrestlers under the names of Tiger and Puma King respectively. Up until mid-2014, his wife, Blanca Rodríguez wrestled under the ring name "Princesa Blanca" but has since retired.

He was a member of the group La Peste Negra ("The Black Plague") from 2008 to 2020, with whom he has held the Mexican National Trios Championship. He has also won the CMLL World Welterweight Championship three times in his career, the Mexican National Welterweight Championship once, and is the current Mexican National Light Heavyweight Champion in his first reign. He has also won several major CMLL tournaments, including the 1999 Torneo Gran Alternativa, the 2001 Copa Ovaciones and the 2002 Leyenda de Plata tournament.
