Chakra nature

The five basic chakra natures are Fire, earth, water, wind and lightning. These five natures make up the vast majority of ninjutsu abilities as everyone is born with at least one, even if they never properly learn how to use it.
Beyond the five basic chakra natures are the combination styles, these are styles that can be learned by combining two different chakra natures. Many of these can also be claimed as kekkei genkai though they are not mutually exclusive. We will be listing each of these abilities and any Clans that may be known for using it. These techniques can be made by combining the separate chakra natures perfectly, while it is more common for multiple users to combine their abilities to gain access to them, those who have all the base elements of the combined types can take a kekkei genkai as a new chakra nature while others will be born with one in place of their normal chakra nature.
