Belladonna is Annabelle's demonic yet beautiful cousin and a recurring villain of the All Dogs Go To Heaven franchise films, the TV series and is the main antagonist of the third film.
All Dogs Go To Heaven: The Series
She first appeared in the episode La Doggie Vita, where, upon her first appearance, Charlie mistakes her for Annabelle. She lies and says that she is Annabelle and is undercover. She sings a song called "Take the Easy Way Out"
An All Dogs Christmas Carol
She plots to use a massive version of the cursed dog whistle to hypnotize every dog in the city into stealing the Christmas presents, causing them to be thrown out of their houses and abandoned (much in the same way Carface was when he was a puppy). Charlie, Itchy, and Sasha move to stop her plan as they try to change Carface's ways by being the Ghosts of Christmas Past, Present, and Future. The now redeemed Carface, having seen himself in the operation-needing Timmy whom he had stolen operation funds from at the beginning of the film, stops the whistle just in time to prevent the dogs from stealing the gifts. Belladonna flies into a rage and is about to kill Carface and Killer when she is frozen solid by a massive amount of snow caused by Annabelle. She is not seen emerging from it.
- The name "Belladonna" is a mixture of the words 'bella' and 'donna'. It is Italian for "Beautiful Lady" and is the name of a lethally poisonous plant.
