Go-zu oni are outwardly similar to other oni, with powerfully built humanoid bodies of prodigious size, but with the heads of beasts. A typical go-zu oni is 9 to 10 feet tall and weighs between 500 and 1000 pounds. Their skin is typically orange, gray, purple, or brown, and they favor wearing fine robes and well-crafted armor to mark their perceived station as creatures of power, wisdom, and cleverness.
