Kershaun Scott is Kody's younger brother and the one of his siblings that follows him deep into the gang culture. Kershaun becomes known as "Li'l Monster." Kody says that a group of younger members, including Kershaun, are being molded into a fighting unit just before Kody is shot. When Kody is faced with his attackers again, it's Kershaun he calls on. Kershaun promises Kody retaliation. Kershaun follows in Kody's footsteps to the point that the brothers are in jail at the same time on more than one occasion. Kershaun also spends a period of time selling drugs. Kershaun, like Kody, turns his life around eventually, marries and has a child.
