Not a single creature but the Philippine term for a whole class of shapeshifting predators — five distinct types in the standard classification, held together by the shared fear of a neighbour who is not what they appear to be.

A category, not a creature
Most English-language writing treats the aswang as one monster. It is not. Aswang is a general Philippine term for malevolent shapeshifting beings, and the figure behind the word changes completely depending on which type is meant.
The classification that organises the field is Maximo Ramos's, published in Western Folklore in 1969. He sorts the aswang into five:
- the vampire — appears as a beautiful woman, drinks blood through a proboscis-like tongue, and may enter a community by marrying into it
- the viscera sucker — the manananggal: a woman by day, whose upper body separates at night and flies off to feed on organs, with a particular appetite for fetuses
- the weredog — usually a dog, sometimes a cat or a pig; hunts at night, especially pregnant women, and arrives in a village in the guise of a traveller
- the witch — the mangkukulam: vindictive, curses her enemies, lives at the edge of the settlement
- the ghoul — eats corpses, gathers near cemeteries, digs up fresh graves
Read as a list, one thing stands out: four of the five are your neighbours. The vampire marries in. The weredog arrives as a traveller. The witch lives at the edge of the village. The viscera sucker is an ordinary woman until nightfall. This is not a fear of the forest. It is a fear of the person next to you, and the detection lore follows from that — it is almost entirely about how to test someone you already know.
The word itself is old and indigenous, reconstructed to Greater Central Philippine *aswang with the sense of vampire, evil spirit or witch, and with cognates across several Philippine languages. It may be the source of the Eastern Indonesian suangi.
How to tell
The tests are concrete, which is what one would expect of a belief about identifying individuals rather than avoiding places.
The famous one is optical. Look into the suspect's eye: if your reflection is upside down, she is an aswang. Witches were said to have elongated irises that invert the image. Beyond that: a dog, cat or pig without a tail; scratching sounds from the ceiling at night; someone who dodges the blessing at Mass. A preparation known as anti-aswang oil was said to boil in the presence of one.
The protections run from the sacred to the crude — holy objects, salt, ash, vinegar, betel nut, urine, stingray tails, the house ladder turned around. Childbirth drew the heaviest measures: sharpened sticks set between the bamboo floor slats, and the husband waving a sword through the space under the raised house, which is where the danger was expected to come from.
Killing one had a procedure too. Strike the witch's back with a bolo and bury the blade; or cut the body and separate the halves across a river. Firearms were considered no use at all.
What the accusation did
This section is here because the aswang is not only a story. The belief has been used against real people, and a site that illustrates the creature without saying so is publishing half the subject.
The disease. Capiz, the province identified with the aswang above all others, has the world's highest concentration of X-linked dystonia-parkinsonism, a rare inherited neurological disorder also called the Dystonia of Panay. The published prevalence for Capiz is about 23.7 cases per 100,000 — against roughly 5.7 for Panay as a whole and 0.31 for the Philippines. Among men on Panay the figure is often given as about one in four thousand. Its visible symptoms — involuntary movement, altered posture and expression, changes in speech — have fed the local legend for generations. People affected by it are widely reported to have been stigmatised and isolated, and in some cases kept from effective medical care because their condition was read as something else. That link between the disease and the belief is made in journalism and in general writing on the aswang; the clinical literature we have checked reports the prevalence without addressing it. The disease is current, the patients are living people, and the folklore is part of what they deal with.
The animals. Bats and Philippine flying lemurs, whose night calls resemble the sounds attributed to a hunting aswang, have been killed on suspicion. A 2019 Philippine television investigation into reported sightings in Negros Occidental produced nothing on camera, and a city veterinarian identified the likely animal as a fruit bat.
The psychological operation. During the Huk Rebellion in the early 1950s, US-linked operatives are reported to have spread rumours that an aswang was killing men in the area, and to have left bodies drained of blood on roads to corroborate them. Edward Lansdale is generally named as involved. The belief was treated as usable infrastructure.
What it looks like
What the record describes. Nothing single, because the category has five members. Each type carries its own appearance: the beautiful woman with the feeding tongue, the flying half-body, the tailless dog, the old woman at the village edge, the thing at the grave. The only features common across the set are the shapeshifting itself and the eyes — specifically, what the eyes do to a reflection.
What film and television added. The Philippine horror industry has given the aswang a consolidated look: a single long-nailed, wild-haired creature with a distended mouth, usually female, usually shown mid-transformation. It is a studio composite of several of Ramos's types and it has largely replaced the folk material in popular awareness.
Origin and sources
Ramos is unavoidable here: the 1969 Western Folklore article (28: 238–248) and Creatures of Philippine Lower Mythology (1971) are the foundation, and most later writing is downstream of them. Damiana Eugenio's Philippine Folk Literature volumes are the other standard collection. Plasencia's letter of 1589 is the earliest colonial description. His osuang flies, kills men and eats their flesh, and he is explicit that it belongs to the Visayas rather than to the Tagalogs among whom he was writing — the regional attribution is there from the first notice. The usual caveat applies: he was documenting beliefs he meant to eradicate, and labels what he records as devil's work.
For the social history, Raul Pertierra's work in Philippine Studies (1983) and Frank Lynch's aswang inquiry are the scholarly entries; the Huk-era material is documented in Scott Anderson's The Quiet Americans and Evan Thomas's The Very Best Men.

Themes
- Good and evil — The commonest question asked of a folk story is whether good defeats evil. Most of the creatures here will not answer it, and what they answer instead is more interesting.
- Shapeshifters — Nearly everything on this site changes shape. What differs is the purpose — and where the purpose is concealment among people, the folklore turns into a set of tests.

Frequently asked
What is an aswang, exactly?
A category. Maximo Ramos's classification gives five types: the vampire, who appears as a beautiful woman and feeds through a proboscis-like tongue; the viscera sucker, which separates at the waist and flies; the weredog, usually a dog, cat or pig; the witch, who curses enemies from the edge of the settlement; and the ghoul, which eats corpses and digs up fresh graves.
Is the manananggal an aswang?
Yes — it is Ramos's viscera sucker, the second of the five types. It has its own page because it has its own name, its own detection lore and its own vulnerability, but it is a type within this category rather than a separate creature.
How do you recognise one?
The tests are specific: an inverted reflection in the eye, a dog, cat or pig with no tail, scratching sounds in the ceiling, someone avoiding the blessing at Mass. An "anti-aswang oil" was said to boil when one came near.
How do you stop one?
Holy objects, salt, ash, vinegar, betel nut, urine, stingray tails, and turning the house ladder around. To kill a witch the record says to strike its back with a bolo and bury the blade, or to cut the body and separate the pieces on opposite banks of a river. Firearms were considered useless.
Why Capiz?
There is no mythological answer, only a historical and medical one. Capiz has the highest concentration of a rare inherited neurological disease, and the stigma attached to its visible symptoms has fed the local reputation for generations.
