Back in 2005, Nickeldeon jumped on board with writers Mike Dimartino and Bryan Konietzko who created the now beloved animated series "Avatar: The Last Airbender," and successor, "The Legend of Korra." Their universe takes place in a world where certain people have the ability to bend one of the four elements, air, water, fire or earth. The four nations are based around these elements as well. One person, the avatar, has the ability to bend all four elements and is his/her duty to keep balance in the world. Last Airbender, is centered around Aang and Zuko who have a parallel journey starting as enemies and end up defeating the firelord, Zuko's father, together. Korra shows the Avatar world 70 years later with more recent technology and even more frightening foes. Now, my question is this: why not move onto a new avatar? Once an avatar, the cycle goes to the next born baby. The way this universe is set up has potential ability for constant new series, characters and avatars. I would personally love to see what Republic City looks like years after Korra's death, and learn about what good she brought to the world after her series ended. After all, she was only 21 by the end of book 4. I understand the writers dont want to relish on the past and want to make something entirely new, but the potential behind this universe is incredible. The avatar world, if properly expanded, can be as monstrous as Harry Potter, or perhaps a less-mature version of Middle Earth.
