They are humanoid creatures so they can be mistaken for people. They got long claws for slashing their prey. The Claw has no face so they only rely on their hearing.
The Claw never tires when it comes to killing. They can jump very high and sprint very fast, but their health is weak. They use their long claws for attacking.
It is the manifestation of Viktor's memory of mythic creatures he had read about when he was young.
