Professional wrestling career Early career (1985–1991) Carrera made his debut in 1985 after being trained by Luis Canales, he would later receive additional training by Rey Misterio. Carrera's first ring persona was a masked persona called "Caballero 2000" (Spanish for "Knight 2000"). After working as Caballero 2000 for a couple of years, Carrera's ring persona was recast in the fall of 1987. He became Ultraman II, patterned after the Japanese Tokusatsu TV show Ultraman, and worked as a successor for the now unmasked Ultraman (Milo Ventura). "Lucha Libre" Magazine renamed him Ultraman 2000 in 1988. Carrera began working for the Mexican wrestling promotion World Wrestling Association (WWA), where he teamed up with Aguila del América and Kiss to win the WWA World Trios Championship from Bill Anderson, Louie Spicolli and Tim Paterson (masked as Los Mercenarios Americanos) on December 12, 1991; this was Carrera's first title victory. Frontier Martial-Arts Wrestling (1991–1996) During 1991 Carrera began working in Japan for Frontier Martial-Arts Wrestling (FMW) where he was billed as "Amigo Ultra", to avoid any legal problems over the "Ultraman" trademark. While working in FMW Carrera's wrestling style was influenced by the Hardcore style of wrestling that FMW promoted. Atsushi Onita gave Garrera a new character: Demian, inspired in the movie The Omen. On July 16, 1993, Demian debuted in the Korakuen Hall. He and Zombi beat Battle Ranger and Eiji Ezaki. His ring persona was diabolical, so he wore facepaint and dark clothes instead of the mask and bright colors of Amigo Ultra. On December 7, 1993, Demian begins a society with The Sheik and Sabu wrestling against Onita, Sambo Asako and Mr. Gannosuke in Chiba's Choshishi Gym. Demian and Sabu
