The Casas family started in
lucha libre in 1964 when José Casas Granados started wrestling under the
ring name Pepe Casas. A second-generation of Casas brothers is also active wrestlers starting with Pepe Casas' oldest son José Casas works under the ring name
Negro Casas, younger siblings Jorge Luiz works as
El Felino and Erick Casas is better known as
Heavy Metal. Pepe Casas has at least one other son, a son who is not involved in wrestling at all but whose children are also third-generation Casas wrestlers. Jorge Luiz' sons are also professional wrestlers, working as
masked wrestlers Tiger and
Puma, This practice does not appear to apply to the Casas family as far as evidence suggests. but it is possible that the true parents of some of the third-generation wrestlers is not entirely accurate, for years Tiger and Puma claimed to be the nephews of Jorge Luiz (El Felino), but later revealed that they were indeed his sons but wanted to make a name for themselves instead of being "Felino Jr." or "El Hijo del Felino" ("The Son of Felino"). ==Members==
