Tenzin is the son of Avatar Aang and Katara and one of the few airbenders of this generation. He believes that nothing not named his family is more important than carrying on the culture of the Air Nomads to upcoming generations and is now training the new ones into becoming the airbending society the world lacked for more than a hundred of years. As Korra's mentor on the other hand, he is always there to consult her on her journey of becoming a fully realized Avatar.
