Nature Transformation

**Nature Transformation** is an advanced form of chakra control that entails the molding and defining of one's chakra into an innate kind of chakra nature, altering its properties and characteristics for use in techniques. Nature transformation is one of two necessary components for creating or modifying a technique, the second component being shape transformation. While nature transformation changes the nature of the chakra, shape transformation changes the actual form and movement, altering its abilities.

## Basic Nature Transformations

The **Five Elements Nature Transformations** are the most fundamental chakra natures, which are the foundation of all elemental ninjutsu. They are so vital to the shinobi lifestyle that each of the Five Great Shinobi Nations is named after one of the five. Each nature is naturally weaker than one nature and stronger than another:

* Fire Style (*Katon*) is strong against **Wind** but weak against **Water**.
* Wind Style (*Fūton*) is strong against **Lightning** but weak against **Fire**.
* Lightning Style (*Raiton*) is strong against **Earth** but weak against **Wind**.
* Earth Style (*Doton*) is strong against **Water** but weak against **Lightning**.
* Water Style (*Suiton*) is strong against **Fire** but weak against **Earth**.

Basically, if an elemental technique is put against another elemental technique of the same level, but of a stronger nature, then the technique with the superior nature will prevail. However, a technique with a weaker nature can overpower a technique with a stronger nature if the former is of a higher level. For example, fire can overpower a water technique if it is first strengthened by a wind technique.

A similar principle applies in how technique of the same element interact, what is called counterbalancing (*Sōsai*). If two techniques of the same nature and the same level are used against each other, they will cancel each other out, as when **Lightning Style: False Darkness** is deflected with **Lightning Blade**. However, if the two techniques have different levels, the higher-level technique will not only prevail but will grow stronger from interaction with the weaker, as when **Amaterasu** (the highest level Fire Style technique) grew stronger by absorbing an opposing **Fire Style: Fire Ball Jutsu**.

## Affinity

In general, every person's chakra has an affinity towards one of the five basic nature transformations. Affinity can at times be genetic, or at least common to a particular family; most members of the Uchiha Clan have an affinity towards the Fire nature. One's affinity can be determined using pieces of paper made from a special type of tree that is grown and fed with chakra: when the paper is exposed to even the slightest hint of chakra, it will react according to the chakra's latent nature:

* **Fire**: the paper will ignite and turn to ash.
* **Wind**: the paper will split in two.
* **Lightning**: the paper will wrinkle.
* **Earth**: the paper will turn to dirt and crumble away.
* **Water**: the paper will become wet/damp.

## Combined Nature Transformations

By using two or three basic natures simultaneously, one can create a completely new nature with unique properties that wouldn't exist on its own. However, doing this requires a kekkei genkai or, if three natures are used, a kekkei tota. It is further stated that those with the ability to combine the elemental nature transformations possess an affinity for the chakra natures they must simultaneously use.
