19 Years Later, a Perfect Avatar Episode Redefined the Show's Greatest Rivalry

One of the things that makes the world of Avatar: The Last Airbender so rich is how much thought series creators Michael Dante DiMartino and Bryan Konietzko put into its history. The introduction to every episode explains the beginnings of the Hundred Year War, where the Fire Nation disrupted the harmony between the Four Nations, and the Avatar wasn’t there to stop them. The show’s plot is primarily focused on the new Avatar, Aang (Zach Tyler Eisen), as he attempts to fulfill the destiny he once fled from and restore balance to the world.
