As a resident of Eulmore, Chai-Nuzz was one of those who indulged in the city's luxuries and is initially shown to be uncaring of people's lives, as he didn't much care for his bonded citizens being tossed out of the city. However, he cares much for his wife and will do anything to make her happy. He is shown to be distrusting or at least doubtful of his own abilities, but is great at planning and an excellent leader.

Chai-Nuzz ultimately redeems himself after organizing the creation of the giant Talos that latches onto Mt, Gulg. After being elected as the new mayor of Eulmore, he swears with all his power to dismantle the laws Vauthry put in place and reestablish the nation, for rich and poor alike.
