Hayopan

The Hyaopan is a form of Aswang from the Philippines. Hayopan are known to settle in swampy areas and keep crocodiles as familiars. It is often interpreted as having no distinction from other Aswang other than them not actively hunting and instead using crocodiles to find prey. These crocodiles hunt and kill, and then bring the best pieces of meat back to their master.
