A new show could also delve into the time between Avatar: The Last Airbender and The Legend of Korra to lay out more of when went down during that span.
When it comes to Avatar: The Last Airbender in particular, Michael DiMartino and Bryan Konietzko have many options.
Even better would be if the creators decided to appoint a new Avatar or two to explore more of that world, either through a new movie, a new show, or both!
They can go back and revisit beloved characters such as Ang, Korra and Katara for new adventures, such as potentially exploring a particular character’s life before the events of the original series.
