Oni of Japan mythology

Oni are one the greatest icons of Japanese folklore. They are large and scary, standing taller than the tallest man, and sometimes taller than trees. They come in many varieties, but are most commonly depicted with red or blue skin, wild hair, two or more horns, and fang-like tusks. Other variations exist in different colors and with different numbers of horns, eyes, or fingers and toes. They wear loincloths made of the pelts of great beasts. All oni possess extreme strength and constitution, and many of them are accomplished sorcerers. They are ferocious demons, bringers of disaster, spreaders of disease, and punishers of the damned in hell.
