Chaz is Chuckie's father, Kira's new husband, and Kimi's step-father. Like his son, Chas also has his adenoidal whine and also seems to suffer from many types of allergies and appears to have asthma.

While he tends to be timid and quiet and a bit whimpy like Howard. He does have a much more of a speaking role. He does try to be more brave, like his son does. He seems to also have a fear of clowns. Like Didi, Chas follows up on the advice of Lipshitz with caring for Chuckie. However unlike Didi, he tries doing things his own way at times. One example could be in "Down the Drain" when he uses a record and his two sock puppets to try and convince Chuckie and Tommy that they don't have to be scared about taking a bath. Despite his allergies, Chas does have a garden and a greenhouse, he's working on.
