The world is dominated by four divine powers (air, fire, water and earth). Among them, the only person in the world who has these four divine powers at the same time is called "divine power". He can stop evil fire nation from conquering the world. However, it is puzzling that he disappeared mysteriously when people needed him most. Thousands of years later, there is still an aquarium tribe in Antarctica. Aquarium warrior katara and her brother Sokka rescued a mysterious boy named Aang 12 years old from a huge iceberg cave. They found that "Aang" was the reincarnation of the long-lost incarnation. "Avatar" was awakened by its own divine power, and finally embarked on the road of saving mankind with its companions.
