 He adopted the ring name "Dos Caras" upon his debut, wearing a colorful mask with a figure of a two headed eagle on it to reflect his name.Rodríguez later stated that the name and mask was not inspired by the Two-Face comic book character but as a "two faced cheater" character (called a "Rudo" or Heel in pro wrestling).Through connections with his older brother who had been wrestling as Mil Mascaras for some years when Dos Caras made his debut he quickly landed a regular job with the professional wrestling promotion Empresa Mexicana de la Lucha Libre (EMLL), the world's oldest and Mexico's largest promotion.
