Balthazor Hellman (voiced by Will Sasso) – The family's patriarch. He is a bit naive but is a very kind-hearted demon. He has a vast knowledge of human behavior from watching much human television in Hell. He almost faced punishment from Satan because of that. He is constantly trying to either get promoted or demoted at work in order to get closer to the drill, the target of which he was sent to destroy. Balthazor is shown to have an evil side too, as he almost drowned Tina's father Zebulon when he insulted his father and tried to get him fired. He appears self-conscious about being overweight as he gets offended when others make fun of it. Despite being a demon, he is overall a nice guy where he cares for his friends, such as when he covered for his friend Chevdet after getting him drunk despite it preventing him from destroying the drill, and deeply loves his family, usually ending each episode having a group hug with his family as well as state "I love you all". He has the power to breathe fire out of all his cavities such as his mouth, nostrils and once farted fire.
