Horror, dark fantasy. Hellhound, demonic wolf. A huge wolf with jet black fur and glowing/shining red eyes. It has an aura of red flames and appears to be on fire. It can breathe these red flames from its mouth, and black smoke exudes from its nostrils. Large, sharp fangs and claws. It roams the night looking for unrepentant sinners, or is sent to collect the souls of those that have made deals with demons. Its usually invisible to most people, but the people or person it's hunting can see it clearly. It moves very fast and can run in mid air if it desires. Once it spots its target, it pursues until the victim is caught and dragged down to Hell. It disappears at dawn, not liking light, for light represents good and God.
