Aang, a 12-year-old boy, is the main hero of the story. He is the present Avatar (the spirit of the planet as a human). As the Avatar, Aang must master all four elements to bring peace to the world and stop the war, which started 100 years ago. Katara, Sokka and Haru helped him to do it. Many characters from the show appear on this game such as Prince Zuko. However, Zuko had a small part in the game, only appearing in cutscenes. King Bumi also appears in the fourth level.
