Werehyena

Belief in the bouda is also present in Sudan and Tanzania, as well as Morocco, where some Berbers regard them as a man or woman who nightly turns into a hyena and resumes human shape at dawn.

[4] In the Kanuri language of the former Bornu Empire in the Lake Chad region, werehyenas are referred to as bultungin which translates into "I change myself into a hyena".

The creature is often portrayed as a magically powerful healer, blacksmith, or woodcutter in its human form, but recognizable through signs like a hairy body, red and gleaming eyes, and a nasal voice.

[7] Al-Damiri, in his 1371 Ḥayāt al-ḥayawān al-kubrā, wrote that hyenas are vampiric creatures that attack people at night and suck the blood from their necks.

[7] The Greeks, until the end of the 19th century, believed that the bodies of werewolves, if not destroyed, would haunt battlefields as vampiric hyenas which drank the blood of dying soldiers.
