Katara (Earth-1529)

"You might have everyone else here buying your ‘transformation,’ but you and I both know you’ve struggled with doing the right thing in the past. So let me tell you something right now. You make one step backward, one slipup, give me one reason to think you might hurt Naruto, and you won’t have to worry about your destiny anymore. Because I’ll make sure your destiny ends right then and there. Permanently!"

- Katara to Sasuke Uchiha

Katara is a master kunoichi waterbender from Konohagakure. Originally coming from the Southern Water Tribe in the South Pole, Katara and, alongside her father Hakoda and older brother Sokka, immigrated to the Land of Fire when she was young during the Third Great Shinobi War. In Konoha, she became a member of Team Kakashi, where she found herself unprepared, both mentally and physically, for the life of a shinobi. However, after being personally trained by Tsunade, the Fifth Hokage, she overcame her obstacles and insecurities, becoming regarded as one of the greatest waterbenders and medical-nin in the world.
