There was a teaser trailer already released a few months ago, and here are some character descriptions that have been shared for the main characters.
Aang is “a fearless and fun-loving twelve-year-old who just happens to be the Avatar, master of all four elements and the keeper of balance and peace in the world. An airbending prodigy, Aang is a reluctant hero, struggling to deal with the burden of his duties while still holding on to his adventurous and playful nature.”
Zuko is “a skilled firebender and the intense and guarded Crown Prince of the Fire Nation. Currently roaming the world in exile, he’s on an obsessive quest to capture the Avatar because he believes that is the only way to reclaim his life and live up to the demands of his cruel and controlling father, the Fire Lord.”
Katara is “a determined and hopeful waterbender, the last in her small village. Though only fourteen, she’s already endured great personal tragedy, which has held her back from rising to her true potential, though it’s never dimmed her warm and caring spirit.”
Sokka is “Katara’s sardonic and resourceful 16-year-old brother. Outwardly confident, even brash, he takes his responsibility as the leader of his tribe seriously, despite his inner doubts over his warrior skills… doubts that he masks with his wit and deadpan sense of humor.”
