Avatar: The Earthbending Revolution
17 parts Complete (Strays from what's cannon) Avatar Korra has been dead for almost 20 years, and people are starting to doubt there will be another avatar. Ever since Raava was ripped out of her, and her connection with the past avatars was lost, Korra always had a tiny doubt there wouldn't be another Avatar. Fortunately, it just took the White Lotus a while to find her. Luna is an unsure Earthbender from a place nearly no one has heard of. But, she is the only one who can even begin to understand and defeat this new threat to the world. But even with her friends helping her, will she even be able to defeat them once and for all? I highly recommend you at least watch The Legend of Korra before you read this. The times, places, and people will make sense. It would be even better if you watch Avatar: The Last Airbender as well.
