In the ancient and mysterious world of the four elements, the existence of supernatural powers symbolizes balance and harmony.They control the power of the four elements of earth, wind, fire, and water respectively, and maintain peace and stability among countries.However, now this hero with endless magical powers faces a new challenge.

Ann, who was only twelve years old, unexpectedly became the new Avatar.Despite his incredible powers, he is full of confusion and insecurity about his identity and mission.His friend, Aba, the flying cow in the sky, became his confidant and partner, and Master Ji'an served as his mentor, teaching him how to use magical powers.

However, just as An was gradually adapting to his identity, the Fire Nation's invasion threatened the peace of the entire world.The airbenders know that only if An learns the magical powers of other elements can they fight against the powerful power of the Fire Nation.Master Ji An decided to tell An the truth, hoping that he could face his fate bravely.

However, the revelation of the truth plunged An into deeper confusion.He escaped from the Sky Temple with Aba, hoping to think about his future calmly.But at this moment, the Fire Nation's army suddenly attacked the Sky Temple, and everyone, including Master Ji'an, was mercilessly killed.

In the chaos, An's supernatural power is activated, his tattoo turns blue, and a violent storm suddenly appears, blocking the way for him and Aba.They were swept out to sea by a storm and ended up trapped in a giant ice mass.

Just when they were in dire straits, brother and sister Katara and Sokka from the Wild Wolf Bay Aquatic Community stumbled upon them.Katara is the only water-bearing descendant with the magical ability to control water, and Sokka is her loyal guardian.They live in isolation and know little about the outside world.

Katara used her water escaping skills to break through the iceberg and rescue Ann and Abba.They explained the history and current situation of Wild Wolf Bay to An. It turned out that in the past hundred years, the Fire Nation had conquered most of the world, and all tribes had fallen into an isolated and helpless situation.Although An was shocked by this, he quickly adjusted his mentality and decided to fight for world peace.

At the same time, Prince Zuko, the son of the Fire King, is also looking for the whereabouts of the Avatar.He was exiled by his father, but in order to fulfill his father's demands, he was determined to find Ann and bring her back to the Fire Nation.Zuko appeared near Wild Wolf Bay when An's Solar Energy ability was activated again.He easily defeats Sokka, forcing An to intervene.In order to save Wild Wolf Bay, An volunteered to become a hostage.

Katara and Sokka were touched by Ann's selflessness, and they decided to embark on a journey to save Ann.Riding on Aba, they finally succeeded in rescuing An after going through untold hardships.However, they realize that returning to Wolf Bay could put the villagers in danger, so they decide to travel to the remaining Sky Temple.
