A trailer has been released for "Legend of Korra - Book 2: Spirit" which is the second season of "Avatar: The Legend of Korra."
Nickelodeon streamed the trailer for the second season of “Avatar: The Legend of Korra” aka “Legend of Korra – Book 2: Spirit.” This trailer was unveiled at this year's Comic-Con in San Diego, California. Legend of Korra – Book 2: Spirit is due to air on Nickelodeon later this year. It is reported that this season will explore the differences between nature and artifice; to be specific, one can expect a lot of modern-world things such as cars, motorcycles, boats, planes, and so forth. You can see that in the trailer.
