Dwun resides in the largest castle on Greed Island, where he is responsible for handing out prizes for the quiz and the ultimate winner.
He is incredibly messy and childish, often mocking Gon for seeking clues to find Ging. The "D" in "Greed" (Island) stands for his first initial. He also asks Gon if he prefers a standard or tailored ending, even though no custom endings exist.
Dwun tells Gon that Ging is a terrible person. His real name is Wdwune. When Ging discovered this, he said, "I see. Then remove the W. From now on, you're D-w-u-n, Dwun."
In his room, it seems Dwun does nothing but chain smoke and play games. He can even use his feet to smoke.
