Yaoguai

Yaoguai is not a single origin myth but a folk category that gathers diverse origins. In Chinese folklore and myth, beings labeled yaoguai may be transformed animals, spirits of objects, wayward local spirits, or other entities that acquire supernatural powers through cultivation, longevity, or malevolent influence. The Wikipedia summary frames yaoguai as defined by their supernatural powers and strange qualities rather than by a single birth‑myth; this implies variability in origin stories across tales and traditions where animals, objects, or unsettled souls become yaoguai through transformation or enchantment.

There is no fixed morphology for yaoguai in the surveyed source; their appearances vary widely. The defining traits are strangeness and transformative capability rather than a single bodily form. In different tales (as suggested by the category), yaoguai may appear as transformed animals, hybrid creatures, disguised humans, animated objects, or otherwise uncanny beings — the emphasis in sources is on variability and the capacity to change form rather than on standardized features.

Yaoguai are strongly associated with transformation and enchantment: they possess supernatural powers that enable shapeshifting, the production of unexplainable phenomena, and the casting of illusions or enchantments that disturb normal life. Behaviorally, they are noted for causing mischief, disorder, and predatory or malevolent actions against humans or livestock. The category covers a range of powers and behaviors rather than a single fixed repertoire, so abilities ascribed to particular yaoguai vary by story.
