The basic idea of the story is on Aang, a young avatar, and his quest to become an expert in the elements of Earth, Water, Fire, and Air.
"Alongside his newfound friends Sokka and Katara, siblings and members of the Southern Water Tribe, Aang embarks on a fantastical, action-packed quest to save the world and fight back against the fearsome onslaught of Fire Lord Ozai," said the official logline for Avatar: The Last Airbender.
Gordon Cormier as Aang; Dallas Liu as Prince Zuko; Kiawentiio as Katara; Ian Ousley as Sokka; Paul Sun-Hyung Lee as General Iroh; Elizabeth Yu as Princess Azul; and Daniel Dae Kim as Fire Lord Ozai are the main cast members of the television series.
