Zoku

Zoku is the current incarnation of the Avatar and direct decent of Fire Lord Zuko – after whom he is named.

Born and raised in the Forest of Flames in the Fire Nation, he was taught to master both firebending and earth bending by his parents.

But first in the age of 16 he discovered that he was in fact the Avatar, when the spirit of Avatar Korra appeared in front of him. She was pleased that an Avatar finally acknowledged her existent and wanted to start Boku's Avatar training right away. Korea tried to teach Zoku waterbending but without success, which lead to Zoku and his younger brother Bumi leaving home in order to find an air- and waterbender to teach Zoku.

In the Land of the Sky the brothers met a small group of Air Nomads.
