A notorious jewel thief on Puckworld, Duke changed his ways to battle Lord Dragaunus. Duke has used a Puck Blaster in some episodes, but he mainly uses a golden sword called a Ducksaber (or sometimes just a 'saber'). He also carries lock picks and a grappling hook attached to his wrist. Duke is pretty level-headed, albeit egotistical at times. He also has an eyepatch and a chipped beak, possibly as a result of his past as a thief (In the episode "Dungeons and Ducks", he tells Borg, "Hey, take it easy, you can put someone's eye out with one of that thing [a sword]. I should know.", which might be a clue to how he lost his eye). He was the leader of a gang called The Brotherhood of the Blade. He remains the most experienced of all the Ducks and possesses a good balance of skill and confidence. Unfortunately, there are some minor trust issues with Mallory due to Duke being an ex-thief, though this fact doesn't seem to faze their leader Wildwing. His name is a pun on the dish duck à l'orange. He is the team's center, and his jersey number is 13. His character design is based on Kurama Wataribe from the Japanese animated series Mashin Hero Wataru.
