I don't really have any normal pics of male Tai-nin, so this'll have to do: Tai-nin in his Super form, drawn by the impeccable  Kalas . TY, Kalassuuuu

If anyone wishes to use this or color it, please ask me first.

Colors are a bit odd. His cuffs are a deep navy blue, his hair and chest floof, as well as the tips of his tails, are an incredibly dark purple (think Shadow Lugia), and his fur is basically a chunk of SPACE. Yes. Stars, blackness, constellations, the whole shebang.
His power can be whatever color you think of, since in this form he controls all form of darkness.
His eyes are the same as normal, a very deep, very shiney gold color.

Also, he has normal-ish fox paws, but anthro-tized. The feet are space as well, and the pawpads and toenails are both a purple-ish blue color.
