Asanbosam
The Asanbosam, Asasabonsam or more commonly Sasabonsam is a vampire-like folkloric being from West Africa. It belongs to the folklore of the Ashanti of southern Ghana, as well as Côte d'Ivoire and Togo. It is said to have iron teeth and iron hooks for feet and to live in trees, attacking from above.
In mythology, it is usually portrayed as an archetypical ogre; according to A Dictionary of World Mythology:
...the hairy Sasabonsam has large blood-shot eyes, long legs, and feet pointing both ways. Its favourite trick is to sit on the high branches of a tree and dangle its legs so as to entangle the unwary hunter.
Both the ogre and vampire versions have iron teeth.
