Oni

Here's my vision of a common Oni from Japanese folklore ! They come in different sizes, skin colors, and a varying number of eyes and horns, but are often like giant hairy humanoids with fangs, wearing clothes made of tiger skin, and armed with a kanabo/tetsubo. Sometimes they're brutish raiders living in the mountains, ruled by Shuten-doji, and other times, they serve as guardians in Jigoku, the Buddhist Hell, under the orders of King Enma.
