This is my vision of the Demigod Loki in wolf form. In humanoid form he looks a bit like Sesshomaru from the Inuyasha anime, but without the annoying attitude. Needless to say, I can't find a stock photo to represent a Demigod with a glowing blue aura, long white hair, a white tail, and fangs. I may commission an artist from Deviant Art to draw Loki.
