Belladonna first appeared in the All Dogs Go to Heaven TV series and Christmas special. She is a beautiful but evil purple Whippet hellhound who is an antagonist in All Dogs Go to Heaven: The Series. She is Annabelle's diabolical cousin. She is voiced by Bebe Neuwirth, who also voiced Annabelle from All Dogs Go to Heaven 2 on.
In PrinceBalto's fanfic remake of All Dogs go to Heaven, Belladonna is reimagined as Annabelle's daughter rather than her cousin.
