Mr. Doppweiller is Doppy's father. He is overprotective. His wife is Mrs. Doppweiller who is also overprotective. One example of him overprotecting Doppy was when he restricted Doppy from the pencil and pen as revealed in the episode of Planet Sheen called "Gotta Go". In "Well Bread Man", he does his job by walking through a blizzard of salt, a beast tears his clothes off, and he does data entry. He is seen in "There's Something About Scary", where him and his wife try to save Doppy and Aseefa from the Scary Face Imprisonment Tower, but become hurt and becomes imprisoned himself. In the end of the episode, he is unimprisoned. He is voiced Rob Palsen.
