<P> The cultures of the four nations are also greatly influenced from Asian and indigenous cultures . The Water Tribe takes influences from Inuit, Yupik, and Sirenik Eskimos cultures; the Fire Nation from Imperialist China; the Air Nomads from the Tibetan culture, Buddhism and Hinduism; and the Earth Kingdom from China with Korean influences . </P> <P> Many of the recurring characters of the series have received traits based on the respective element . Aang is carefree and childlike, as is commonly attributed to "wonder" of the unknown, or the "freedom" of the wind and the air . As a spiritualist, a pacifist and a vegetarian, he is very Yin and notably feminine, hyper - attuned to the spirit world, and prefers non-violent alternatives to solving problems . Unlike her predecessor Aang, Korra is very Yang and distinctly masculine; she was inspired by various female MMA fighters and is "very tough, very headstrong, and not scared to get into a fight," as attributed to Water's attributes . Her stubborn realism and hot - headed personality prevents her from easily learning airbending or connecting with the Spirit World . Toph, despite being blind, is extremely perceptive of the world around her due to her connection to the Earth . Unlike Aang, she is extremely brusque when criticizing others, as attributed to Earth's toughness . </P> <P> Avatar Aang (Chinese: 安 昂; pinyin: Ān Áng) (voiced by Mitchel Musso in the unaired pilot, voiced by Zach Tyler Eisen in Avatar: The Last Airbender, voiced by D.B. Sweeney in The Legend of Korra, and portrayed by Noah Ringer in The Last Airbender) is the protagonist of the original series and the current Avatar, a cyclically reincarnating being who maintains world balance . Aang often acts in a fun - loving, carefree manner . His pacifism and vegetarianism are primary traits of Buddhism . The creators intended Aang to "defeat enemies with his wits" and be a "trickster hero". Though Aang is often frivolous and enthusiastic, he becomes serious during a crisis . </P> <P> In the original series, Katara and Sokka rescue Aang from a century of suspended animation . Having already mastered his native Airbending, Aang learns Waterbending at the North Pole in Book One, Earthbending from Toph in Book Two, and Firebending from Zuko in Book Three . Throughout the series, Aang aids the Water Tribes and the Earth Kingdom, whom the Fire Nation has oppressed . Unwilling to kill Fire Lord Ozai despite the past Avatars insisting on it, Aang ultimately learns the ancient Lion - Turtles' technique of energybending, which allows the user to give or take away a person's bending, and uses it to render Ozai a non-bender . </P>
