What supernatural entity is described as a beautiful woman that uses black magic?

The description of a supernatural entity as a beautiful woman who uses black magic aligns with the characteristics of a witch. In many cultural narratives, witches are frequently depicted as women who possess the power to cast spells and manipulate magic, often linked to malevolent practices like black magic. The allure of beauty combined with magical abilities is a common theme, representing both seduction and danger.

While other entities listed have unique characteristics, they do not fit the description as closely. For example, the Penanggalan, a spirit from Southeast Asian folklore, is associated with a disembodied head that flies around at night, which contrasts starkly with the idea of beauty and enchantment. Jinn are supernatural beings in Islamic theology, often portrayed with more complexity, including various personalities and forms, but not specifically as beautiful women wielding black magic. Strigoi refers to Romanian folklore involving the undead, primarily focusing on the notion of vampirism rather than the concept of a witch practicing black magic.

Thus, the entity that specifically fits the description of a beautiful woman using black magic is indeed a witch, making it the most accurate choice.
