Okay, this is interesting. It seems the Kirin Subspecies only really appears when the Kirin appears but, why is unknown. Also similar to Kirin's color being caused by lightning, its most likely black due to the icy enegry inside of it, which somethings suggest that it may have lost its lightning abitilys due to something.
