Worgen?

Worgen are large, lupine humanoids reminiscent of a werewolf that walks upright, but lopes on all fours to run. According to sources held by the Forsaken, the worgen come from another dimension, and exist only to terrorize and destroy. These creatures are thoroughly evil, delighting in torturing and devouring intelligent creatures. They enjoy hearing the screams of their victims as they tear them apart piece by piece. Worgen never show mercy or remorse. They may seem savage, but they are fairly intelligent and possess a cruel bestial cunning that can come as a surprise to the unprepared.
Most worgen keep their wolf-like forms at all times, but experiments by the mage Arugal have resulted in human/worgen hybrids who only appear as worgen under the light of the moon. They carry with them a dark, corrupting malaise that grows wherever they infest, making the surrounding area dark and gloomy.
Worgen are among the few humanoids that can be skinned.
