Board Thread:Theories and Speculation/@comment-1512913-20180917223942/@comment-4636509-20180919121951

Once upon a time, I had a theory that it's possible to combine 5BN with secondary elements like Yin and Yang. The theory I had in mind was actually based on the fact that Sasuke used Blaze Release, but it wasn't confirmed to be a combo of Fire & Lightning (yeah, I remember the times when some fans suggested this combination).

So, for me, it was that Blaze Release is made up of Fire nature (Uchiha Clan has an affinity for it) and Yin Release (the one that includes any specific chakra manipulations, genjutsu creation, favor of spiritual energy over the physical one, etc.).

Now, with all the info we have about any showed release, and the theory I have, I can suggest this stuff to discuss. First of all, we confirmed natures like:
 * Boil (Fire + Water)
 * Scorch (Fire + Wind)
 * Lava (Fire + Earth)
 * Storm (Water + Lightning)
 * Ice (Water + Wind)
 * Wood (Water + Earth)
 * Dust (Fire + Earth + Wind)

Then, we have some natures that are indeed troublesome. Let's begin with the Magnet Release. It's known to be a trait of One-Tails and all its jinchuriki, I don't know why nobody has mentioned it. According to the databook, Shukaku has only Wind and Earth nature, leaving them as a basis for the Magnet. A pity, as I consider Lightning + Wind as a more appropriate variant for this (and I also consider that Gaara should have Magnet from Shukaku, not only his father, as it’s going to be wrong that Naruto had Magnet from Shukaku, and Gaara hadn’t).

Then, we have Explosion Release. In the manga, it was said that this nature is made up of at least earth nature, because of the seal Deidara used to make his clay figures, and because Sasuke was able to stop the former’s jutsu with his lightning, as lightning travels through the earth. I consider that Explosion nature is indeed lightning + earth; the reason Sasuke was able to stop the explosion, is because his Lightning Release was more powerful than the lightning component Deidara put in his techniques. Counterbalancing stuff, y’know.

Now, we can talk about the theory I have, a combination of five basic natures and secondary natures. I consider that Blaze and Typhoon can be combinations of Fire and Yin, and Wind and Yin, respectively; because Yin is based on spiritual energy, and more chakra-based, thus it can work like this. According to this, we can have such variants of KG:
 * Crystal: Earth + Yin
 * Steel: Earth + Yang
 * Dark: Lightning + Yin
 * Swift: Wind + Yang

I also considered that Wisdom Wolf Decay might be based on a combination of Water and Yin Releases, thus giving the acid nature.

So, what do you think about it? IDK, if my theory sounds crazy or nobody will like it, but I'm interested in a discussion :P
