Kōryū

Koryu is Soten's dragon servant.

Personality
Koryu is very loyal to his mistress, Soten, and is proud to serve her and the Thunder Demon Tribe, of which Soten is the last surviving member. Still, he is sometimes exasperated with Soten and her pushy attitude and will sometimes quip her shortcomings and try to remind her of her limits, only to get yelled at, and he is somewhat more mature than her. Koryu can be quite devious and underhanded, and is proud of his dragon heritage, snapping at anyone who calls him a snake or a worm, and seems to be proud of his "power", feeling insulted when IuYasha calls his energy arrows a joke and pathetic. He has a big mouth for his size and goaded ImuYasha to strike him on the head thrice, as was needed for him to transform. Koryu is still a bit of a coward as he prefers to use tricks to get he better of his opponents.

Koryu doesn't seem to like being a bad guy as he once stated "It's hard being the bad guy all the time."

Powers and abilities
Koryu has the ablity to shapeshift into a thundercloud upon being struck in the head three times.
 * Shapeshifting:
 * Energy Arrows: In his thundercloud form, Koryu can unleash a barrage of energy arrows at his enemies. However, the arrows are extremely weak to the point of where they don't inflict damage at all.

As he is a dragon, Koryu can obviously fly.
 * Flying:

Koryu uses tricks and traps rather than directly face his opponents, using a boulder to sepperate Shippo from his friends, incapacitating Kirara with catnip, and a pitfall trap on Miroku and Sango by using a dummy shaped like a maiden and throwing his voice to make it sound like she was in distress to lure the peverted monk and Sango into the trap. He attempted to use a Kagome dummy to get InuYasha to "sit" but did not realize it only works if the real Kagome says sit.
 * Tricks and Traps:

Trivia

 * Koryu's name can mean "little dragon" or "baby dragon"
 * Koryu made a dummy of Kagome with the exact same clothes, but where did he get modern age clothes in Feudal Era Japan?
