Werebats appear as enemies in the Misty Forest Road level. They attack by throwing little bats, and slide backward if the player attempts to attack them from too close. If they spot the player, they will sometimes exclaim: "Let's play, cute little kitty!"
They are the only enemies in the game that drop the Arma Chiropteraglyph. This allows Shanoa to transform into a werebat herself. It has a 2 star drop rating, so she won't drop it too often.
