He is a vigilante, gang leader of the Aztecas, gangster, and a rapper; his rapper name is C-Mob. Caesar/Cesar is revealed to be a kind, loyal, caring, and selfless person. His loyalty comes from when he stops his gang members from fighting with Carl in the mission Cesar Vialpando. He also assures Carl he will take care of his sister Kendl and make sure she is brought no harm, which is exactly what he does. When it comes to Kendl, he is genuinely kind and protective towards her, as seen in the mission Deconstruction where he attempts to confront the construction workers for harassing her. The only negative characteristic of Cesar's is his lack of patience, as he might lose his temper if things take longer than planned. This is seen in the mission Puncture Wounds, in which he becomes very angry just because he failed to steal a car on his own. Cesar is also revealed to be afraid of heights, as seen in Customs Fast Track. Cesar is quite the opposite of his cousin Catalina, who is a ruthless, selfish, and extremely arrogant person. However, Cesar still does not want others to disrespect her, seen by his reaction when Carl calls her a "bitch" in front of him.
