Eustacio Jiménez Ibarra was a Mexican luchador enmascarado, or masked professional wrestler, better known by the ring name of El Hijo de Cien Caras. The name is Spanish for "the Son of Cien Caras." He was not, however, related to wrestler Cien Caras, but instead paid Cien Caras for the rights to use the ring name, a practice not uncommon in Lucha Libre. He also wrestled under the names Frankenstein and Suplex, named after the monster and the wrestling move. He was the brother of Adolfo Tapia, who wrestles as L. A. Park as well as the nephew of Super Parka, the cousin of Volador Jr., the uncle of El Hijo de L.A. Park and the great uncle of Flyer.
