Zack (played by Trevor Wright) is the main antagonist of the show. He is Mel's son and Jack's nephew. He is shown to be quite rebellious and never listening to his father. It is stated that he was kicked out of school, vandalized the factory (in the episode "Wrecking Ball") and got a girl pregnant at a previous school, simply to infuriate the principal. He begins a secret relationship with Carmen towards the end of season 3, deceiving her into thinking he cared for her, although it later turned out that he only dated Carmen with hopes of getting her into bed and planned to leave her right afterward. In the season 3 finale, he runs away with her and takes $5,000 with him. He is known to date many other girls only for sex, even sleeping with his principal's daughter. However Carmen does not give in when Zack attempts to sleep with her at a hotel, even trying to get her drunk just to do so, which also fails. When he realizes Carmen was not going to give in and sleep with him, he breaks up with her and leaves her in San Francisco at a club before going back home. When he got back to his home town, Mel finds him sleeping on the couch and brings him into the factory to confront a furious George about Carmen's whereabouts. After confessing to leaving Carmen at a nightclub, he runs outside where Benny hits him with a wrench. It is mentioned by Carmen that the reason for Zack's undisciplined behavior stems from his father not being there for him and having a "bitter old drunk" of a mother.
