Deon Wilson

He is first seen after Deon installs the new software into him, which response with child-like terror upon powering up. Deon and Yolandi calm the robot, teaching it words and naming it "Chappie". Despite Deon wanting to stay with the robot, Ninja forces him out of their hideout.

Yolandi wants to mother Chappie, but Ninja grows impatient with his development due to both the impending deadline for the debt and Chappie's irreplaceable battery running out, giving him days to live. Ninja tries to train Chappie to be a gangster by leaving him to fend for himself in a dangerous neighborhood, where he is attacked by a group of thugs and later seized by Vincent, who has found out about Chappie after following Deon to the hideout. Vincent successfully extracts the guard key for his own use, but the traumatized Chappie soon escapes from him and returns to the hideout. Yolandi scolds Ninja for this mistreatment, but he soon manages to persuade Chappie to turn to crime by training him in martial arts and weapon handling. Ninja and Yankie trick Chappie into stealing cars for them and lie to him about needing the money to replace his dying body.
