Fire Nation; the element of fire is a light, active element and is contrary to Water. Firebending, one of the four elemental bending arts, is the pyrokinetic ability to control fire. Fire is the element of power, consisting of overpowering force tempered by the unflinching will to accomplish tasks and desires. 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 Tribes; the element of water is a heavy, passive element and is contrary to Fire. Waterbending, one of the four elemental bending arts, is the hydrokinetic ability to control water, as well as its many forms. 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 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.

Air Nomads; the element of air is a light, active element and is a contrary to Earth. Airbending, one of the four elemental bending arts, is the aerokinetic ability to control and manipulate currents of air. Air is the element of freedom. The Air Nomads detached themselves from worldly problems and concerns; finding peace and freedom was the key to solving their difficulties in life. Airbenders continually sought spiritual enlightenment, and, as a result, all children born into the Air Nomads were benders. The key to airbending is flexibility and finding and following the path of least resistance. Airbending is notable for being almost purely defensive, as well as the most dynamic of the four bending arts. Airbenders can overwhelm many opponents at once with large and powerful attacks that could prove fatal; however, due to the pacifist nature of the Air Nomads, such attacks are rarely used. Due to aforementioned spirituality, they often adapt to the situation surround them and prefer to dodge an opponent instead of a direct attack.

Earth Kingdom; the Element of Earth is a heavy, passive element and is contrary to air. Earthbending, one of the four elemental bending arts, is the geokinetic ability to manipulate earth and rock in all their various forms. Earth is the element of substance, making earthbenders and their people diverse, strong, persistent, and enduring. The key to earthbending is utilizing neutral jing, which involves waiting and listening for the right moment to strike and, when that moment comes, acting decisively. In other words, earthbenders generally endure their enemies' attacks until the right opportunity to counterattack reveals itself, then strike with unyielding force.
