So I was wondering, if all of the White Zetsu are victims of the I.T. that have been transformed, why are they not all unique or why are they not all the same? Most of the Zetsu are very similar, with the green hair and so on, but the only truly unique white zetsu seems to be guruguru, or Tobi. Is there a canonical reason for this, or is this another example of Kishimoto not knowing where he was going to take the story at the time? I love Naruto and I love speculating, so please post what you think is the reason behind this conundrum. Personally I don't think there's any good canonical reason for it.
