31 Days of Monsters 2014: The Aswang

The Aswang is a vampire/werewolf-like creature from the Philippines. Variously described as taking the form a dog-, pig-, bat- or cat-like monster, the aswang is a shapeshifter, who lives during the day as an unsuspecting member of the community. At night, however, the aswang transforms into a horrific beast that thirsts for blood and decaying human flesh. Aswangs are ghouls and eaters of the unborn. Aswangs will raid graves and eat corpses, leaving wooden dummies behind in the empty graves. These dummies will take the form of the dined-upon victim and rise from the grave to help spread the aswang curse. Some aswangs are described as having a sharp proboscis or tongue that they use to suck the blood from expectant mothers and their unborn children.
Despite these unsavory habits, during the day, while in human form, an aswang is described as being quite a nice neighbor to have. They form close ties with other humans during the day, taking pains to hunt far from home so as not to harm those they call friends.
