Arturo Casco Hernández (March 17, 1961 – September 12, 2010) was a Mexican luchador, or professional wrestler, best known under the ring name La Fiera, which is Spanish for "The Wild Beast".

Hernández was a second-generation wrestler, following in the footsteps of his father Hércules Poblano ("The Hercules from Puebla").

[3] While his career slowed down by the 1990s due to age and injuries, he experienced a small comeback of sorts in 1996 when he teamed with Dos Caras and Héctor Garza to win the CMLL World Trios Championship from Bestia Salvaje, Emilio Charles, Jr. and Sangre Chicana.

Hernandez was heavily involved with drugs toward the end of his life, having previously served a prison sentence in the 90s for dealing them.

On September 10, 2010, Hernandez was stabbed five times during a mugging by an unknown assailant, and died from his injuries two days later at a Mexico City hospital, at the age of 49.
