I just had an idea you know how avatars come once the last one dies. What would happen if the avatar turned out to be a twin, would there be two avatars? Or will only one be chosen as an avatar?
Also just another idea you know how Avatar Wan got his powers from the Giant Lion Turtle what if a normal person meets these turtles and some how gets there powers will there be two avatars. For some reason I am obsessed with the idea of having more than one avatar at a a time.
