Cesar Vialpando

History
Little is known about Cesar's life prior to 1992, though at an unknown point in time he joined the Varrios Los Aztecas, a Hispanic street gang, eventually working his way up to become the leader. Cesar also began a relationship with Kendl Johnson, to the disapproval of her brother Sean, the leader of the Grove Street Families. Cesar displays excellent driving skills, especially when it comes to lowriders. During Customs Fast Track, Cesar reveals that he is acrophobic.

Events
Cesar first meets Carl Johnson at a lowrider competition. Despite Carl's initial distrust of Cesar, the two eventually form a close friendship and a working relationship between their two gangs.

Like Carl, Cesar and Kendl were forced to leave Los Santos after the savage Ballas' ambush on the Grove Street Families, and his gang's influence in the city diminished sharply. While in exile, he gets Carl into some grief by introducing him to his cousin, Catalina. After arriving in San Fierro, he and Carl cooperate to get revenge on the people who double-crossed them. Together, they were able to kill T-Bone Mendez. Later, Cesar puts his driving skills to good use by aiding Carl in obtaining several sports cars for their newly established car business.

Background
The duo eventually return to Los Santos, and Cesar helps Carl and Sweet reclaim territories for the Grove Street Families. Carl repays Cesar's efforts by helping Cesar reclaim the Azteca's territories. During the same mission, Cesar informs Carl of his intention to propose to Kendl. Carl gives Cesar his blessing, but Cesar asks Carl to discuss it with Sweet because of the latter's earlier distrust of Cesar. Cesar appears in the final mission, where he witnesses Frank Tenpenny's death in the centre of Grove Street. He is later seen inside the Johnson House, and joins the celebrations when Madd Dogg announces his new gold record.
