Fear Eater

Source: Harker's Guide to Vampire Hunting

The fear eater is a shapechanging creature that takes whatever form it believes is most likely to induce fear in its prey. Fear eaters are very hostile, but unlikely to kill their victims, as they feed on the victim’s fears — and while many creatures fear death, they fear nothing once they are dead. Fear eaters are known to stalk their prey for days on end and to attack while they rest. The best defense against a fear eater is to remain calm, as they have little interest in those who do not fear them.
