By werewolf, I'm not talking about normal humans who can transform into big beasts and transform others to be like them. I'm just purely talking about could the werewolf form be its own wild animal? The werewolf form being a large, bipedal, and carnivorous creature with a canine face and sharp claws that only hunts at night.
The more I think about it, the mythological werewolf actually resembles a bear more than a wolf. But why would a bear-like creature only hunt at night and walk on two legs? And would a creature like this fit any of Earth's biomes?
