True, but it's possible there are some other minor differences like their hairstyles being slightly different. That and I have yet to see any fanart of a older Kunou, if there is then I have not seen it. Plus I find it easier to see an image than try to imagine it in most cases.

Either way, all the others I can't use that trick for anyways. Despite Sieg is said to be a white Kiba, I doubt he's just Kiba with bleached hair, for one he's likely missing Kiba's mole.
