Han-Gyojin

半魚人

Han-Gyojin (lit. half merman or merman) is a water youkai and an antagonist of Kitarou.
Han-Gyojin and Umi-Nyoubou share their designs. In the 1971 anime, Han-Gyojin is a youkai that is half-fish and half-human, thus possessing features of both; he is covered in purple scales with a few visible barnacles and has magenta webbed feet. His human features include a human-like build with a fit physique, arms and legs each having five digits, and facial features such as ears and a nose. His head has light purple skin, long black hair that reaches his waist, eyes with white sclerae and small black pupils, and a mouth with sharp teeth.
Within the 1985 anime, Han-Gyojin appears relatively the same, though he seems shorter and has a stout physique. He has light indigo scales, webbed feet, white claws, light purple skin with whiskers on the sides of his face, and long purple hair that reaches his knees. His eyes are white with small black pupils, and his mouth is filled with more teeth.
In the 1996 anime, Han-Gyojin's appearance is relatively the same; he appears shorter than Nurarihyon and has an average physique. He has green scales and skin with a few visible dull brown barnacles, webbed hands and feet, long light purple hair that reaches his legs, and four pairs of whiskers on his face. His eyes have yellow sclerae with small black pupils, and his mouth has sharp teeth.
There has been another type of Han-Gyojin which more closely resembles traditional images of mermen in western cultures.
