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.

Shapeshifting is the default

Eleven of the thirteen creatures on this site change shape, which makes the tag almost useless as a filter and interesting as a question. If nearly every figure in two unrelated traditions is a shapeshifter, the transformation is not what distinguishes them. What it is for is.

Sorting them by purpose gives three groups, and the third is the one with consequences.

One: the shape is the environment

The leshy is the clearest case. His height is not fixed — accounts put him anywhere from a giant stepping across rivers to something the size of a blade of grass, and in several the rule is explicit: his height matches the vegetation. Tall as the pines where the pines are tall, lost in the grass of a clearing. He also appears as a tree, a stump or a mushroom, and as a bear, a wolf or a black goat.

Read literally that is a trick. Read as the material probably intends, he is not a being of a certain size who lives in the forest; he is the forest's own scale taking a shape. The same logic produces his other attributes — invisible, shadowless, impossibly heavy. These are not a creature's properties. They are a place's.

The kapre works similarly on a smaller scale, bound to one specific large tree and invisible unless it chooses otherwise, and turning hostile when the tree is cut down.

Two: the shape is an approach

Here transformation is a method of getting close, and the chosen form is a lure.

The zmey Gorynych is the surprise in this group. The many-headed fire-breathing serpent of Russian epic takes human form on the ground — a handsome young man — and uses it to court women. In Afanasyev's tales he seduces Ivan Tsarevich's sister, and elsewhere Ivan's wife. He also appears as a golden goat and, least dignified and most domestic, as a broom and an oven fork. A Western hoard-guarding dragon does none of this.

The tiyanak is the purest version: it cries like a newborn until someone picks it up. And the lure is not really a disguise. In the belief it is a dead infant, one that cannot pass on because no one named it, doing precisely what its situation requires — crying where it might be found. The horror and the pathos are the same mechanism.

The tikbalang belongs here too, though its method is illusion rather than impersonation: it can turn invisible or take human form, and its working technique is to turn travellers around so that however far they walk they come back to the same stretch of path.

Three: the shape is concealment among people

This is where shapeshifting stops being a feature and starts organising a whole body of folklore.

In the Philippine aswang complex the shape is a disguise for living in a village. Maximo Ramos's classification gives five types, and four of them are your neighbours: the vampire marries into the community, the weredog arrives as a traveller, the witch lives at the settlement's edge, and the viscera sucker — the manananggal — is an ordinary woman until dark, when her upper body detaches and flies.

The consequence is that the lore is almost entirely detection. Not weapons: tests.

look into the eye — if your reflection is inverted, you have found one
a dog, cat or pig with no tail
scratching from the ceiling at night
someone who dodges the blessing at Mass
an "anti-aswang oil" that boils when one is near

Every one of those is a test you apply to someone you already know. This is not a fear of the forest. It is a fear of the person next to you, and the shapeshifting is what makes the fear unfalsifiable.

The manananggal is the limit case, because her concealment has a physical flaw. The lower half of her body stands where she detached, motionless, until she returns. Anyone who finds it and puts salt, ash, garlic or fire on the exposed flesh prevents her rejoining, and she dies at sunrise. The detection problem that organises the entire complex — how do you know what your neighbour is — here has a literal answer lying in the undergrowth.

What this cost

The aswang detection lore was applied to real people, and the shapeshifters tag is where that belongs on the record. Capiz, the province most identified with the belief, has the world's highest concentration of a rare inherited neurological disorder whose visible symptoms fed the legend; people affected by it have been stigmatised, isolated and in some cases kept from treatment. Bats and flying lemurs have been killed on suspicion. During the Huk Rebellion the belief was used deliberately as a psychological operation.

A creature that can look like anyone is a convenient accusation. Four of Ramos's five types being neighbours is not an incidental detail of the folklore; it is what the folklore was for.

The two that do not change shape

Rusalka and bakunawa, as it happens. One is what a person became; the other is a cosmological scale. Neither needs a second form — the first is already a human shape and the second is too large to pass for anything.
