The weretiger is often a dangerous sorcerer, portrayed as a menace to livestock who might at any time turn to man-eating.

The aswang is a vampire-werewolf who transforms from a human to a canine form at night, and eats human flesh. The aswang also manifests itself as a decaying corpse that has been severed at the waist (in other words...it has nothing from the waist down)... with batwings. They are very closely related to the Berbalang ghouls of legend.

The southern Filipino berbalang are a sort of ghouls or vampires who fly through the air in their astral bodies in the form of a swarm of reddish fireflies in search of human victims to devour and kill.

When not flying through the air as swarms of reddish fireflies making  a horrid howling or moaning noise, they look like ordinary human beings distinguishable only by their cat-like eye pupils. The  berbalang were described in 1896 by a Hong Kong based English anthropologist named Ethelbert Forbes Skertchley, who had spent a few  years on Cagayan Sulu in the extreme southern Philippines studying  local customs and beliefs, in a paper on "Cagayan Sulu, its Customs,  Legends, and Superstitions," in the _Journal of the Asiatic Society of Bengal_, Vol. LXV, Part III, Np. 1, 1896. Skertchley even claimed to have had a personal close encounter with the berbalang in their moaning firefly-cloud astral phase! Rupert T. Gould summarized and quoted Skertchley's paper in his chapter on "The Berbalangs of Cagayan  Sulu" in _Oddities: A Book of Unexplained Facts_  (1928). Most   subsequent popular 20th century accounts of the _berbalang_  have  basically been rehashes of Gould's summary of Skertchley.

China

Chinese legends often describe weretigers as the victims of either heredity or a vindictive ghost. Ancient teachings held that every race except the Han Chinese were really animals in disguise, so there was nothing extraordinary about some of these false humans reverting to their true natures. Alternately, the ghosts of people who had been killed by tigers would become malevolent supernatural beings, devoting all their energy to making sure that tigers killed more humans. Some of these ghosts were responsible for transforming ordinary humans into man-eating weretigers.
