This is all my own speculation about the nature transformations. I will only consider manga elements and I won't include Yin-Yang combinations, because I think they won't be present on manga history after all.

My ideas

 * Sand Release: it's a combination of Earth and Wind element.


 * Metal Release: it's a combination of Earth and Lightning element.
 * 1) Metals are found on the earth and are electrical condutors.
 * 2) The series used a lot of Taoism concepts, just like the Wood element. It is very possible that it will feature a Metal element too, and the most suitable combination for it would be Earth and Lightning.

Thanks ShounenSuki for the icons and Omnibender for ideas and inspiration.
