Diego and Armando Mendez
Diego and Armando Mendez are the two biggest cocaine dealers in Vice City circa 1984, when Grand Theft Auto: Vice City Stories takes place. Diego is the more quiet of the two and only speaks Spanish, while the more charismatic Armando is the one with greater control of the organization. Reni implies that he/she had relations with Diego. They also own a Domestobot, which was destroyed by Armando when Victor Vance took control of it and destroyed his bonds. Armando is killed, along with many of his bodyguards, by Victor after Louise is killed by Armando. In the final mission, Vic - in a Hunter helicopter - attacks the Mendez compound killing many of the bodyguards. He is shot down, but manages to land safely and make it to the rooftop, where he kills Diego (and Martinez) during a three-way shootout between the men.
Armando seems to be based off of Scarface's Alejandro Sosa as he bears a striking resemblance to him and his personality is similar to Sosa's also. Their names are a play on Argentinian soccer star, Armando Diego Maradona.
The voice actor for Diego is Ruben Trujillo, while Armando is voiced by Yul Vasquez.
