Bending battle
From avatar the last air bender. I'm going to do this the best way I can.
This is and in his adult form. Each character can only go into the avatar state once. The setting is place where there are plentiful mountains, lakes, rocks everywhere. No blood bending, lighting, smoke, flying(like we zaheer) metal, sand, or any other external branch offs. Just water, fire, earth, and air.
Avatar battle.
Aang vs Roku vs Korra vs Kyoshi
Which avatar is the true avatar.
