Duke

Duke is a huge black-and-white tom kittypet with yellow eyes, a spiked black collar, along with several nicks in both his ears.

The Lost Warrior

 * Duke is a kittypet who is noted to be very aggressive. It is known by other cats that he has never lost a fight against another cat.


 * When Graystripe first goes out of his Twolegs' territory, he meets Duke. Graystripe calls him fat and lazy angering Duke. He decides to fight him. Graystripe, however, is still weak from being kept in the Twoleg Nest so long, and loses the fight. This makes him stop and think if he is still truly a warrior of ThunderClan, or if he is turning into a soft kittypet. Soon after his fight with Duke, Millie, another kittypet, comforts him by saying that no cat has ever won a fight against Duke.


 * Later, when Graystripe is training Millie to be a warrior in a clearing in the small forest by the Twolegplace, Duke comes in with two other kittypet companions. He tells the two to leave, saying that it is his clearing, even if he hardly goes there, thus starting another fight. This time, training with Millie had strengthened Graystripe, and they win the fight. Duke runs off, calling Graystripe a savage.

Warrior's Return

 * Although Duke does not formally appear, he is mentioned when Graystripe is fighting with some kittypets.
