Black Dragon

Black Dragon (黒龍, Kokuryū),is a powerful Dragon who is a personal summon of Kukan Yami

Appearance
Black Dragon is a gargantuan, mastodon dragon whose entire upper body is covered in black, round, scales, which, in turn, are decorated by spiraling, blue markings. His lower body, specifically his belly, inner tail, and legs, are grey in color, and appear to be rather smooth. The Dragon's eyes are white and beady, and his head is round and blunt with four, large, elongated plates extending backward. His mouth is full of razor-sharp teeth, and, attached to his chin, is a protrusion that resembles an arrowhead. His large wings are feathery in appearance, akin to a bird's. The scales disappear at the end of The Dragon's tail, which, in itself, ends in a stinger-ques shape.

Nature Transformation
Black Dragon is if not strongest then stronger than others, a Dark release user, able to use Dark release techniques out of his mouth, making him a formidable force against other Release users and summons.
