Representing his native Mexico, Dos Caras Jr has deep roots in the amateur and pro-wrestling worlds. Both his father (Dos Caras Sr.) and uncle (Mil Masceras) were world-wide stars as professional wrestlers. Dos Caras Jr. began as a member of the Mexican national team in Greco-Roman wrestling and from there went on to numerous accomplishments: he placed third at the World Junior Championships in 1997 (held in the Czech Republic), won the Central-American games three times and also earned a medal at the Pan-Am games. Caras also intended to compete in the 2000 Olympics in Sydney, however, due to lack of support and funding (as well as political squabbling), Mexico did not send any wrestlers to compete. After this, Caras "turned pro" and began following in his father and uncle's footsteps as a professional wrestler. Hungry for actual competition, he then moved on to mixed martial arts, competing in the DEEP promotion in Japan. MMA training included tutelage under the legendary Marco Ruas. The name "Dos Caras" means "two faces" in Spanish and refers to the mask he wears in pro-wrestling. Caras is a graduated of the University of Mexico where he earned a degree in architecture.
