Fire Nation

Firebending, one of the four elemental bending arts, is the pyrokinetic ability to control fire. It is unique among the bending arts, as it is the only one in which the performer can spontaneously generate the element. While the first human firebenders were the Sun Warriors, it has since spread to the people of the Fire Nation, and the United Republic. Fire is the element of power, consisting of overpowering force tempered by the unflinching will to accomplish tasks and desires. However, during the Hundred Year War, a militaristic Fire Nation twisted this into firebending being fueled by rage, hatred, and anger. Firebending draws its power from the sun, and the first human firebenders derived their firebending techniques from the dragons. Firebending is notable for its intensive attacking style and general lack of adequate defense moves, although some notable firebenders utilize creative defensive techniques by creating large walls of fire, or shooting down incoming objects with precise attacks.

Water Tribe

Waterbending, one of the four elemental bending arts, is the hydrokinetic ability to control water, as well as its many forms. This type of bending is utilized by the people of the Water Tribes, who are divided into the Southern, the Northern, and the lesser known Foggy Swamp, as well as those of the United Republic, each with their own unique bending style. Water is the element of change. The moon is the source of power in waterbending, and the original waterbenders learned to bend by observing how the moon pushed and pulled the tides. The Water Tribes are the only people who did not learn bending from an animal, though the Moon and Ocean Spirits took the form of koi fish in the mortal world near the beginning of the Avatar World. The fighting style of waterbending is mostly fluid and graceful, acting in concert with the environment. Foggy Swamp style waterbending, however, is more rigid and straight. Waterbenders deal with the flow of energy; they let their defense become their offense, turning their opponents' own forces against them.
