I think we should make one about a girl who controls fire and has always been bullied about it in her past. now she has met a person that controls earth one that controls water and one that controls air/sky/wind. now they are looking for a stone which could balance the world. The world right now is in bad shape with villains and everything. but the main character always has tantrums and her fire keeps blowing up stuff. so she has to learn to keep it under control. oh yeah, and she doesn't really get along with the guy that controls water so there's always tension. could be funny

The Girl Fire Bender?

"Avatar: but there's only four of them"
Regardless, I quite like it.
