Before Garuba showed up, Capcom already stated Kusha had subspecies in the series.

If generations continue to feed on the special ores and they all do it every generation and the diet is what causes their body to change, I would consider them their own true subspecies. I mean you can see directly through the tail and fingers like its a glass window if hes like that all the way to the bone(Looks like his bones are made of glass and see through...) I would think hes a subspecies.
