Bloody Tongue Aspect of Nyarlathotep, from the Call of Cthulhu game the the Cthulhu Mythos.
The model is 3" (7.5cm) tall, and except for a hollow in the torso (to make the teeth look more menacing) is solid and weighted towards the bottom. It should be very sturdy and stable for use in a roleplaying game or for display.
Using most game stats I've been able to find, this version is approximately to scale with standard DnD minis.
As for materials, I recommend Alumide for the smooth finish, or Black Strong & Flexible. If you want to go super fancy, I imagine he would look quite nice in Black Glass or Antique Bronze Glossy,
