Nature Transformation



Nature Transformation (性質変化, Seishitsu Henka) is an advanced form of chakra control and a technique that is pivotal for the manipulation chakra and the creation of new jutsu. While Shape Transformation changes the shape and movement of chakra, elemental nature transformation changes the actual nature of the chakra, altering its properties and characteristics. It is notable that few shinobi can use both shape manipulation and nature manipulation.

Nature Manipulation/Transformation is one of two necessary techniques for creating a jutsu, its counterpart being Shape Transformation. Nature Manipulation entails the molding and defining of one's chakra into a innate type of chakra nature.

Basic Types
There are five basic types into which the nature of chakra can be transformed, called the Five Elements Nature Transformations (五大性質変化, Godai Seishitsu Henka). These five types are also called elements and are not only the origin of the names of the Five Great Shinobi Countries, but also the foundation of all elemental ninjutsu. The five basic natures are all connected to each other in a circle, each being weaker than one and stronger than another.

These elements allow for elemental ninjutsu to be performed: Basically, this means that if an elemental jutsu is put against an elemental jutsu of the same level, but of a stronger nature, then the jutsu with the superior nature will prevail. However, a jutsu with a weaker nature can overpower a jutsu with a stronger nature if the former is of a higher level.
 * Fire (火, Hi) natured chakra allows for Fire Release (火遁, Katon), which is strong against Wind but weak against Water.
 * Wind (風, Kaze) natured chakra allows for Wind Release (風遁, Fūton), which is strong against Lightning but weak against Fire.
 * Lightning (雷, Kaminari) natured chakra allows for Lightning Release (雷遁, Raiton), which is strong against Earth but weak against Wind.
 * Earth (土, Tsuchi) natured chakra allows for Earth Release (土遁, Doton), which is strong against Water but weak against Lightning.
 * Water (水, Mizu) natured chakra allows for Water Release (水遁, Suiton), which is strong against Fire but weak against Earth.

Affinity
In general, every person has chakra that has an affinity towards one of these types, a characteristic that seems to be genetic, since whole clans sometimes share the same affinity. Most members of the Uchiha clan, for example, had an affinity towards the Fire nature.

To find out what affinity someone has, pieces of paper made from a special type of tree (that are grown and fed with chakra) are used that react to even the slightest hint of chakra in any of a number of ways, depending on the nature latent in the chakra.

The Chakra Paper reactions are as follows: This affinity makes it easier to learn how to create and control the nature in question, although even with an affinity this process will usually take any number of years. Shinobi are not limited to the nature they have an affinity to, though. By the time they reach the rank of Jonin, most shinobi have mastered two natures. However, because of the difficulty of mastering a nature and the time required to learn it, it is almost impossible to master all five natures in normal way. However, people who are born with the Rinnegan possess all the elements, while Kakuzu got them stealing the hearts, and chakra, of others.
 * Fire: the Paper will ignite and turn to ash.
 * Wind: the Paper will split in two.
 * Lightning: the Paper will crumple up.
 * Earth: the Paper will turn to dirt.
 * Water: the Paper will become damp.

Advanced Types
Besides the five basic nature types, there are several more advanced types. By using two basic types simultaneously, one can create a completely new nature with unique properties, and is referred to as a "elementally-recomposed nature type". Doing this requires a special ability and such abilities are rarely seen outside a kekkei genkai.

So far, eleven natures have been shown: http://
 * The Ice (氷, Kōri) nature, used by Haku, is created by simultaneously combining the Water and Wind natures. This nature allows for the use of Ice Release (氷遁, Hyōton) ninjutsu. Ice Release has been shown as being strong against Fire Release. Yukigakure-nin and Renga were also able to use Ice Release techniques without the kekkei genkai, by drawing on already-existing ice and cold.
 * The Wood (木, Ki) nature, used by Hashirama Senju and Tenzō, is created by simultaneously combining the Earth and Water natures. This nature allows for the use of Wood Release (木遁, Mokuton) ninjutsu.
 * The Lava (溶岩, Yōgan) nature, used by the Four-Tailed Monkey and the Fifth Mizukage, is created by simultaneously combining the Fire and Earth natures. This nature allows for the use of Lava Release (熔遁; 溶遁, Yōton).
 * The Crystal (結晶, Kesshō) nature, used by Guren, is created by simultaneously combining the Earth nature and lightning natures. This nature allows for the use of Crystal Release (晶遁, Shōton) ninjutsu. (Anime-only)
 * The Blaze (炎, Honō) nature, used by Sasuke Uchiha, originates from the flames of Amaterasu and allows the use of Blaze Release (炎遁, Enton) ninjutsu. It is unknown what this nature entails.
 * The Storm (嵐, Arashi) nature, used by Darui and stolen by Hiruko, is created by simultaneously combining the Lightning and Water natures. This nature allows for the use of Storm Release (嵐遁, Ranton) ninjutsu.
 * The Boil (沸騰, Futtō) nature, used by the Fifth Mizukage, is created by simultaneously combining the Water and Fire natures. This nature allows for the use of Boil Release (沸遁, Futton) ninjutsu.
 * The Dust (塵, Chiri) nature, used by Ōnoki, is created by simultaneously combining the Earth nature and wind natures. This nature allows for the use of Dust Release (塵遁, Jinton) ninjutsu.
 * The Dark (冥暗, Meian) nature, stolen by Hiruko, allows the use of Dark Release (冥遁, Meiton) ninjutsu. It is unknown what this nature entails. (Movie-only)
 * The Steel (鋼, Hagane) nature, stolen by Hiruko, allows the use of Steel Release (鋼遁, Kōton) ninjutsu. It is unknown what this nature entails. (Movie-only)
 * The Swift (迅速, Jinsoku) nature, stolen by Hiruko, allows the use of Swift Release (迅遁, Jinton) ninjutsu. It is unknown what this nature entails. (Movie-only)

Speculation
http://
 * Gaara and the One-Tailed Shukaku's sand manipulation is also thought by some fans to be an elemental fusion of Earth and Wind natured chakra.
 * The Third Kazekage had a special magnetic chakra unique to him, allowing him to use his signature Iron Sand techniques. While no official sources have called it a chakra nature, some fans speculate it may be a combination of Earth and Lightning natures.
 * The steam used by Han, the jinchūriki of the Five-Tailed Dolphin Horse might be an advanced nature. There is no mention of a "Steam Release," or "Steam nature," though.
 * The bubble-style ninjutsu used by Utakata, the jinchūriki of the Six-Tailed Slug might be an advanced nature. There is no mention of a "Bubble Release," or "Bubble nature," though.

Combining with Shape Transformation
main article: Shape transformation

While Nature Transformation changes the shape and movement of chakra, Shape Transformation allows a ninja to change the actual shape and actions of the chakra, altering its abilities. Because of this, a technique like Rasengan can be turned into Wind Release: Rasengan or Wind Release: Rasenshuriken, because of Wind Release being joined with the movement of chakra. The cutting nature of wind-natured chakra into millions of minuscule blades, in a spiraling formation, turns as seen when used against Kakuzu.

Yin and Yang
Aside from the five basic types of nature transformation, there is also a sixth type: the transformation of the Yin (陰, In) and Yang (陽, Yō) nature of chakra. Not much is known about this so far, but Yamato implies that it is the source of certain non-elemental jutsu such as Shadow Imitation Technique, Multi-Size Technique, medical ninjutsu, and genjutsu. It is unknown whether this type of nature transformation is similar to the elemental nature manipulations or whether it is a completely different kind of nature transformation.

It is implied that the transformation of the Yin and Yang has to do with altering the amounts of physical-mental energy in chakra. As explained by Shikamaru Nara, Tayuya's spirit worms were starving chakra imbued with the mental energy to feed (though having small amounts of physical energy), thus so they require stability and they feed upon the physical energy they lack. It was also commented by Shikamaru that Tayuya is the same type of shinobi he is, one who is able to use "special chakra" to use in techniques.

When the Fourth Hokage sealed the Nine-Tailed Demon Fox within his son, Naruto Uzumaki, he split its chakra into a Yin and a Yang, sealing only the Yang half within Naruto. This suggests that the Yin and Yang nature is inherent to chakra and is merely altered, while chakra has to actually be transformed to gain an elemental nature.
