"Avatar: The Last Airbender" borrows extensively from East Asian art to create its fictional universe. Four "bending" arts exist in the universe; they are based on different styles and variations of Chinese martial arts: Baguazhang for Airbending, Hung Gar and Southern Praying Mantis for Earthbending, Northern Shaolin for Firebending, and Tai Chi for Waterbending. Additionally, series borrows heavily from the Taoist concept of balance and order. The Avatar, an incarnation of a divine being, is supposed to maintain the world's order.
