Three new videos have emerged for Nickelodeon's upcoming The Last Airbender: Legend of Korra, the sequel to the much-beloved Avatar: The Last Airbender cartoon. Set 70 years in the future after Avatar, the upcoming animated series follows a spirited protagonist named Korra who has mastered Earth, Water and Fire-bending -- all of which she uses to kick some serious butt in the new clips -- on her journey to master the final element, Air. One video even features a conversation with an elderly woman who may be Katara from Avatar.

Last Airbender fans should also be on the lookout for Avatar: The Last Airbender - The Lost Adventures, a 240-page Dark Horse Comics collection that fills in some of the gaps between the two series, which hits comic shops later this month.
