Mandurugo

The Mandurugo is a creature from the Capiz people of the Philippines. Its name means “bloodsucker.” It commonly takes the form of an attractive woman to lure people in, though their true form is a rotting corpse with sharp teeth. Sometimes they are thought to be a form of undead, but sometimes is thought to be a form of living vampire. This living form of Madurugo will lead a normal human life but will go to their window at night when others are asleep, transform into a flying monster, and hunt for blood. They can be hurt with weapons, but not killed. They are vulnerable to fire and little else.
