I will give clues

if I was a fire bender in the fire nation, what will I be and what will I do if I was.

years later I am still a fire bender, but I am living peacefully, but I was attacked by people in costumes with sticks of blue energy and a man with a hood and a mask came and took my bending away forever.

and now, I am a non-bender still living peacefully in a new place made by the last air-bending avatar

what do you think what I want to see battle?

I will give it out later to people who do not know what I was explaining about , but now, I will keep it a secret.
