La Fiera

Arturo Casco Hernández (March 17, 1961 – September 12, 2010) was a Mexican luchador, or professional wrestler who was 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"). His brother wrestled as Ángel Poblano.

Fiera held the NWA World Welterweight Championship from October 23, 1981 when he defeated Lizmark for the title until July 18, 1982 when he lost the championship to Américo Rocca. He would later hold the NWA World Middleweight Championship, defeating Gran Hamada on November 18, 1984, holding it until July 20, 1985 when he lost the belt to Chamaco Valaguez. 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. The team was forced to vacate the title in 1997 when Héctor Garza left the promotion. La Fiera had been in semi-retirement since the early 2000s. During this final period of his career he wrestled only on a few select dates a year.

He died on September 12, 2010 after being stabbed five times.
