Look like 20yr human man but is can turn into a Ninja Dragon (https://www.dragon-mania-legends.wiki/wiki/Ninja_Dragon), gender is male, his Hair color is dark silver or black, his Eye Color is dark red, his face peer out of a mask of black with white outlining. This mask juts out past the back of its head to form a crest and is attached to two spikes protruding from the side of its head. Its neck and back are covered in feathery black plates. Two sharp, three-bladed shurikens protrude from its spine. A twisted, bright red rope is tied around its waist; and a red harness, which is held together by a silver cross, drapes across its chest. Its tail ends in a sharp point like the tip of a spear. Each flipper is protected by a red fin-pad, the front ones having two small white spikes, while the rear has only one small white spike, without his mask but with a little bit shy face when show his face, his stealthy nature is very useful in battle, but annoying when bath time rolls around and this trainer discovers it's replaced the soap with a throwing star... again!
