Exciting wrestler who made his debut in late 2008 working local CMLL shows in Arena Coliseo de Guadalajara. Often teamed with his friend Saturno in the early days. Scored the biggest win of his career on July 19, 2009 when he won a Cage of Death Match to unmask Azazel. Gained more attention for his crazy high flying maneuvers. Debuted in Mexico City as part of the Mexican National Trios Contenders Tournament, 2010 with fellow Guadalajara natives Metal Blanco & Sagrado. Returned to Guadalajara for a few months, but returned to Mexico City in April for the Gran Alternativa and Forjando un Idolo tournaments. He and Metal Blanco continued to team up, though no longer with Sagrado.
Both Palacio and Metal Blanco disappeared from Mexico City in early November. The two were brought back a few weeks later (their third debut in under a year) as Titan & Triton, new proteges of Shocker to feud with Reyes del Atlantida. Metro was also announced as part of this iteration of the Guapos, but had little involvement after the press conference. Titan & Triton appeared to stay away from their previous signature moves to conceal the identities, but it was obvious to all who knew the previous gimmicks by their first match. CMLL does not acknowledge Titan & Triton's previous identities, but it's not treated as a secret in Guadalajara and luchadors have alluded to their previous identity.
The rivalry with Atlantis' trio was short lived. It only lasted two weeks before Shocker was left out of CMLL due to personal problems. Titan & Triton did not fare well in the weeks that followed, and CMLL suggested this was a losing streak for the lack of a mentor which would end when they got a new one, but the whole concept was dropped and Titan & Triton resumed wrestling in terceras with no particular direction. The two still are booked as strong local favorites in Arena Coliseo Guadalajara. Shocker did return to CMLL, but there's no hint of reunited him with the tag team.
