Tsu'hak is the leader of the Ni'awve clan.
Tsu'hak was prepared to move with his clan away from the Valley of Origins after humans came too close to the clan's hometree. He joined with Tsamlok and Ryan Lorenz to make the way safe from humans, but was captured. Since Tsamlok was injured during his capture, it was Ryan Lorenz who came to Tsu'hak's rescue. Ryan lent Tsu'hak his banshee and he rode back to hometree. Having a chosen one of Eywa on their side, Tsu'hak was about to launch a full scale attack at Hell's Gate, but when Ryan Lorenz was shot while in his link unit and his avatar body also died, the attack was stopped.
