This Krampus looking guy is the moon champion from Hate: Mother Prophecy. I'd use him as a devil or as some kind of elemental dream demon. He appears to be coming out of a puff of smoke so he's clearly a summoned being. Makes him work as a devil or demon in any fantasy RPG game, especially Dungeons & Dragons
Model is 3.5" tall. 32mm scale, but he works as a big bad guy for 28-38mm scale.
