She was thought to be a protagonist, because she seeked Monica's help to defeat Dr. Screem, but Screem reveals that Belladonna was the true villain.
Belladonna first came as a desperate, innocent woman who needed help. But later on, she was revealed to be vile.
Belladonna was a pretty, young woman (possibly in her 30s) with straight black hair, round dark eyes, high cheekbones, and a warm smile. She wore a soft and flowy black dress that fell to her ankles like a nightgown.
- Belladonna is referenced in the Goosebumps story arc Horrors of the Witch House, when Clarissa tags her on what appears to be the social media equivalent of Twitter for witches.
