California luchador who achieved national fame when he debuted on Lucha Underground's 3rd episode as a restaurant worker from down the street recruited by Dario Cueto to fight back against complaints about the lack of Mexican luchadors on the show. Cuetro promised Mariachi would sing a song if he won; Mariachi has never won. Mariachi makes up for it by dancing during his matches. Mariachi Loco is much more successful on the indies, expanding out to Arizona indies in 2015.
