This cube craft paper toy is Aang, a male Air Nomad born in 12 BSC and the Avatar during the century-long conflict known as the Hundred Year War, based on the American animated TV series Avatar: The Last Airbender (Avatar: The Legend of Aang in Europe), the papercraft created by SKGaleana.
His immediate predecessor was Avatar Roku, and his immediate successor is Avatar Korra. As the Avatar of his time, he was the only person capable of using all four bending disciplines: airbending, waterbending, earthbending, and firebending. He was also one of a select few Avatars, and one of the first in many cycles to learn the ancient art of energybending, and the first Avatar known to have actively used the technique.
Shortly before the beginning of the Hundred Year War, Aang was frozen in an iceberg for a hundred years; he emerged, still biologically twelve years old, into a world engulfed by war. During his absence, the Fire Nation had waged war upon the other nations and managed to completely wipe out the pacifistic Air Nomads. It fell to Aang, the last airbender and the Avatar, to put a stop to the War by mastering the other three elements and defeating Fire Lord Ozai. He remained something of a kind, goofy kid at heart throughout his year-long struggle, despite the overwhelming loss of his people and the heavy burdens he was forced to bear. After his victory over the Phoenix King, Aang began a romantic relationship with his close friend, Katara. The couple eventually married and raised a family of three children: Kya, a waterbender, Bumi, a non-bender, and the youngest, Tenzin, an airbender. [Source: wikia]
