Who do you think is the bravest avatar character?
This is extremely hard and I hate you.
Off the very tip-top of my head, I say Zuko. I will admit, I am partially biased towards him as he is my sweet fire son, but at the same time, he did commit treason and leave behind all normalcy to help Aang and Company.
Then, I was going to say Katara. She found Aang, fought Pakku, traveled the fucking world over, got herself imprisoned, took out a crazy waterbender, posed as a spirit, befriended the Fire Nation prince, and defeated the Fire Nation princess. I mean… that takes a lot of courage.
But, you know what else takes courage? Leaving your tribe behind, leaving your post as protecter behind, and following your ‘magic’ sister and her ‘magic’ friend on a journey that started because of a random twist of fate. It takes courage to see your faults, to admit your weaknesses, to fight for something you’re scared to believe it (i.e. magic water and such) and overcome it all.
So, I’m going to say Sokka.
