Nuka joined Claw Heart Pack as a young pup with his sister Cassi and half-brother Sir(formerly King) Nava, and realized his love for hunting. When he turned a year old, he joined his own hunting party alongside Cassi, Waldhund, Sir Nava, and Honey. Although he never had a mate or fathered any pups, Nuka was able to lead a happy and fulfilling life.
