ATLA

You are an innocent boy/girl in the fire nation, who never really cared for war. One day, you see, Aang, Toph, Katara, and Sokka all running in the village. You get curious and you decide to follow them. Just because you are a kid, doesn’t mean you’re bet at fighting. You are really skilled, that Aang wants you to teach him, after you guys fight (ignore the voice)
