Fideo is a mariachi who works at a "mariachi joint" (as opposed to a strip joint) and is a good friend of El Mariachi .
Fideo is a drunk, who couldn't care less about the fact that he is gonna be fired. He drinks rather than practicing shooting or playing. However, Fideo is alot more moral than Lorenzo is and doesn't just play for money.
Fideo's weapon is a guitar case that is remote controlled like an R/C car and blows up on command.
He later helps El Presidente escape along with Lorenzo, and they are both rewarded and go their separate ways.
