Aswang

The Philippine equivalent of the Vampire, this creature is the most feared of all the Filipino monsters. The Aswang is a normal man or (most often) a woman by day, but by night transforms into a bat-winged monster that devours the flesh and blood of its human prey. The Aswang is a sorcerer or a witch that, through the study and practice of the dark arts, acquires an incredible array of supernatural powers, including shapeshifting (most often taking the forms of cats or dogs).
