His ring name is Spanish for " The Son of the King of Mystery " or more correctly " The Son of Rey Misterio " , however he is in fact the nephew of the luchador , Rey Misterio . He is also the cousin of Rey Mysterio , who started his career as " Rey Misterio , Jr . " He mainly works on the independent circuit in the United States , especially in California and in Mexico , especially in Tijuana , Baja California . Hijo de Rey Misterio ' s real name is not a matter of public record , as is often the case with masked wrestlers in Mexico where their private lives are kept a secret from the wrestling fans .

El Hijo de Rey Misterio grew up in a wrestling family with both his father and his cousin being very well known " Luchadors " .

He made his professional wrestling debut in 2006 , initially working under the ring name Diablo . By the end of 2006 his father gave him permission to use the " Rey Misterio " name and he became " El Hijo de Rey Misterio " . The name has led to some confusion , especially when wrestling in the United States where a lot of fans have mistaken him for the son of Rey Mysterio , but Mysterio is actually his cousin . Some promoters have actively sought to exploit this confusion by neglecting to bill him as " El Hijo de " and just billed him as Rey Misterio . In one controversial case a Bolivian promoter used World Wrestling Entertainment footage of Rey Mysterio to promote a tour by El Hijo de Rey Misterio , when Hijo de Rey Misterio found out he cancelled his tour . When El Hijo de Rey Misterio cancelled his tour the Bolivian promoter had someone else wrestle under the mask , pretending to be El Hijo de Rey Misterio . Since adopting the " Hijo de Rey Misterio " name he has been working mainly for Pro Wrestling Revolution ( PWR ) in Northern California , shows in Tijuana and made various independent wrestling promotion appearances in America .

The duo defended the title a couple of times during 2008 but were forced to vacate the title in June , 2009 as Rey Misterio , Sr . suffered a serious injury . He has stated that while he likes working in the United States he really wants to focus on a wrestling career in Mexico , hoping to work for Consejo Mundial de Lucha Libre ( CMLL ) or Asistencia Asesoría y Administración ( AAA ) , Mexico ' s two largest professional wrestling promotions .
