Gyokko

Gyokko had a very bizarre and grotesque physiology, taking on the form of a pale white, abstracted, grotesque humanoid figure with a muscular upper torso that has no arms and resembles that of an armless statue growing from a porcelain vase, similar to a djinn. His midsection is a red-violet color while his lower-half, or his tail is black. He had multiple underdeveloped and infant-like hands with red fingernails; four on his head that replaced his ears and were always present, and several lining up his body and tail which he can retract at will. He also possessed thin fins on the top and back of his head that were akin to hair, which were of a blended hue of purple and a blue-violet color and shaped in the style of cornrows and a ponytail.

Gyokko's face was even more distorted, with large green-lipped mouths located where one would expect his eyes sockets to be located, which always displayed his hyperrealistic teeth and sometimes had one of or both of his tongues sticking out. His actual eyes were located vertically from one another on his face; one eye appeared in the constantly open bottom mouth and the other was seated at the center of his forehead. Three dots were on top of the latter eye. The kanji for Upper Rank (上じょう弦げん, Jōgen?) was engraved on his forehead's eye and the daiji for Five (伍ご, Go?) was engraved on his mouth's eye. In addition, his twin green mouths are generally expressionless and only move when speaking or eating, while the mouth that displays his lower eye is the one that contorts to display Gyokko's emotions.

When in battle, Gyokko was shown to molt and transform into his true form, which bore heavy resemblance to that of a merman. In this state, Gyokko retained his facial features and muscular physique but now possessed a more humanoid body with two large arms replacing his many small ones, and his body became covered in transparent scales akin to a fish. He also grew much larger and attained a mane of longer fish tail-like hair, dark markings on various places around his body, webbed hands with turquoise blue scales, and a long, teal, serpent-like tail in place of his legs. In addition, the mouth which displayed his lower eye had 4 stitches, with 2 on each side, giving it a rag-doll like appearance.
