It’s been nearly four years since Avatar: The Last Airbender concluded its original run on Nickelodeon, and in that time the Eastern-influenced fantasy epic has spawned a live action motion picture, a comic series and more. What fans were really waiting for, however, was a true animated series sequel. This Saturday, fankind gets its wish as The Legend of Korra makes its on-air debut. Set 70 years after the events of The Last Airbender, The Legend of Korra introduces a powerful young Avatar to her world’s most populous and complicated city, where she’ll have to overcome crime, corruption and a masked menace working to turn non-benders against those who can manipulate water, earth, fire and air. ComicsAlliance reached out to The Last Airbender and Legend of Korra co-creators Michael Dante DiMartino and Bryan Konietzko to learn more about their own four-year journeys bringing the new animated series to life.
