Demon Beasts Horrors (魔獣ホラー Majū Horā?) are fictional monsters and the antagonists in the Tokusatsu series Garo.
Originally from a Demon World (魔界 Makai), the normal variety of Horrors, called "Inga Horrors" (陰我ホラー Inga Horā, "Yin-Self Horrors") which are grotesque black-winged skeletal demons. An Inga Horror enters the human world by being attracted to the darkness inside human beings that its kind feed on, using an object as a portal to travel from the Demon World. Those items, called Inga Gates, are objects with large amount of darkness from either playing a role in some sort of naturally accumulated atrocity like mass murder or a traumatic experience left unresolved. There are also Inga Gates that are created by someone infusing the object with dark energies. Regardless, all Inga Gates are usually activated when person with inner darkness approaches them, with the emerging Horror turning that person or any other living thing nearby into a host body. From there, the Horror "evolves" into a unique form based on the Gate they emerged from with personal tastes and feeding habits. In some cases, instead of taking complete control, an Inga Horror can form a symbiosis with the host to act out the human's dark desires. Regardless, a human is dead the moment an Inga Horror possesses them and what remained of the host follows the Horror in death. Though rare, there are also some unusual Horrors that prefer to possess objects rather than living thing, not having a preference of prey as they consuming whoever comes into close contact one way or another instead. But the rarest Horrors are the ones that assume the form of large beasts without needing a host body, acting only on a primal and indiscriminate urge to feed. As revealed in Guren no Tsuki, Horrors have influenced humanity's myths such as the people of Heian-kyō believing them to be Preta.
