The Avatar team is starting production on Season 3 right away, ideally keeping the gaps in Aang’s journey to a minimum. Avatar Season 2 will follow Aang on his ongoing quest to master the four natural elements: air, water, earth, and fire. In Season 2, Aang will master water (curiously, he doesn’t waterbend much in Season 2) and struggle with the element of earth. Princess Azula takes center stage in Avatar Season 2. Avatar: The Last Airbender Season 1 is now streaming on Netflix.
