Adze Vampire

My interpretation of the Adze. The Adze is a vampire from African (specifically Ewe) mythology with firefly-like traits.  They have a firefly form which makes them invulnerable, and a human form that lets them possess humans and take on their characteristics. The best way to trap one was to use coconut water and palm oil. 

The axe he's holding is also called an adze.
