Dragon Lord is a green dragon Yo-kai. It has an ivory-colored, scaly underbelly, lined with orange. He has orange fur on his head with two orange tufts and a purple tuft in the middle. He has two purple horns forked into two. He has blue eyes, two orange whiskers, and sharp fangs. He has clawed feet, and in one he clutches a blue orb. On the tip of his tail, he has a yellow-orange tag. He has orange spines along his back.
Dragon Lord is based on a ryū, or Eastern dragon. Originally from China, these creatures are less like yo-kai and more like actual deities (for which they're called ryūjin, or "dragon gods") that were worshipped in ancient times, and are unrivaled in both wisdom and power. They're associated with rainfall, rivers, and floods, and tornadoes are said to be dragons rising to the skies (hence the Japanese word for tornadoes - tatsumaki, literally "dragon's coil"). In China they are also associated with the imperial rule.
Texts speak of the ryū's "nine resemblances": they have a deer's horns, a crocodile's head, a demon's eyes, a snake's neck, a tortoise's belly, a fish's scales, an eagle's claws, a tiger's feet and a bull's ears. Alternatively, as part of the Chinese zodiac they are said to incorporate characteristics from all other 11 animals. They are usually portrayed holding a flaming pearl in their claws, which they especially treasure and will fight fiercely over. Somewhere on their body there is an inverted scale, and if anyone touches it they will become infuriated and tear the offender apart. From there, "touching the inverted scale" became an idiom for provoking the emperor's wrath.
