Significantly less prominent than the Vagos, the Varrios Los Aztecas are a Mexican gang. They will attack other GSF members on sight, and vice versa, usually ending with many deaths of Aztecas if GSF had guns on them. The Varrios are rivals with the Vagos and the San Fierro Rifa, and are also believed to be on bad terms with the Ballas. They are based on the Sureños.
The Varrios are traditionally anti-narcotics, with heavy involvement in gun running and street violence, and they only have a few territories compared to other gangs, and these are clustered around the south-western areas of Eastern Los Santos. Varrios Los Aztecas members are mostly seen wearing turquoise bandanas and sunglasses, dressed in 'cholo' style clothing of the time. Sunny, Gal and Hazer are other gang veterans who help Cesar and Carl recover some of their lost territory near the end of the game. The Varrios are also traditionally into lowriding and have betting competitions which are called the Lowrider Challenge which can be found at Unity Station after talking to a man with a bandana and gray working outfit on the outside wall of the station's parking lot.
