Katara is one of only two current Waterbenders from the Southern Water Tribe, a race of people who can control and manipulate water, because continuous Fire Nation raids on her village have taken away all other waterbenders. Katara earns the title of Master Waterbender from Master Pakku of the Northern Water Tribe by the age of fourteen, a rare feat.
She and her older brother, Sokka, discover an Airbender named Aang, the long-lost Avatar, frozen in an iceberg and accompany him on his quest to defeat the imperialistic Fire Nation and bring peace to the war-torn nations.
Katara is also very nurturing, acting as den mother for the group. She usually cooks their meals and washes their clothes. She takes responsibility for her brother, Sokka, and later Toph, and especially Aang (although initially she took a very mercenary attitude toward him, viewing him more as someone who could help her become a Waterbender than a friend). These tendencies were shaped by the fact that her tribe's losses from Fire Nation raids and the departure of so many members of the tribe to fight the Fire Nation forced her (as well as her brother Sokka) to take on numerous responsibilities beyond her age. Her maternal instincts, while with good intentions, can sometimes make her bossy.
Katara tends to be the most sensitive and compassionate member of the group (with the possible exception of Aang.) She can be very kind and generous, and she tends to be the most trusting in new situations. However, she can become very angry if someone hurts or insults her, or especially if she feels someone has betrayed her; she can allow anger to cause her to say or do unwise things, and she can carry a grudge against someone who has betrayed her for a long time, as was the case with Zuko.
Ultima roleEditShe along with Aang's friends were once on a quest finding the Chaos emerald with the Ultimawielder.
Katara also been given a new modern-battle outfit by the Society for cope standard environment.
