The animated television series Avatar: The Last Airbender features a list of characters created by Bryan Konietzko and Michael Dante DiMartino. Taking place in a fictional universe composed of four sovereign nations, the Avatar--a being who represents the bridge between the physical and the spirit--alone holds the power to master all four elemental powers but has been mysteriously missing for the past 100 years. During this absence, a war started by the Fire Nation's belligerent attempt to conquer the world resulted in the Air Nomads' genocide, the Water Tribes' near extinction, and the Earth Kingdom's extensive colonization which thus sets up the world in which the characters of the series live.
