Then, Aang went into the avatar state and sent the Fire Nation ships away. The fire nation succeeded but Princess Yue, Sokka's girlfriend, sacrificed herself to save the moon spirit. Their goal was to destroy the water tribe and destroy the moon. Everything was going great until the fire nation came. She became his best student, easily surpassing everyone else.

Realizing this, he agreed to teach Katara. He had been engaged to her but she turned him down. She lost but he found her amulet and realized that it was her Grandmother's. However, he would not teach Katara because she was a girl, and as such she was furious and later fought him to prove her worth. They traveled for a long time, but they finally reached the North Pole where they went inside and found a waterbending teacher, Master Pakku. Their main goal was to get to the Northern Water Tribe, there they could find a Waterbending master for both Aang and Katara. Katara and Sokka agreed to travel with him. Aang agreed to give himself up but later escaped.

Her and her brother took Aang back the her village, where trouble was caused because Zuko, an evil fire bender and the banished Prince of the Fire Nation, was tracking the avatar and came to the village to look for him. After an intense argument with Sokka, the combination of her emotions and lack of control of her powers resulted in her accidentally destroying the surrounding area, and subsequently freeing Aang from the ice. She and her brother, Sokka, found Avatar Aang and Appa, his sky bison, frozen in ice. Her mom was killed by fire benders and her father and the other men left to fight in the hundred year war. Katara comes from the water tribe where she is the last remaining waterbender in her village.
