Dock ferrys people across the water, and operates the docks. Which he says he gets his name from. His other personality Xu which he says is his twin brother, operates the village fishmart. He introduces a third personality at the end of the episode which he says his his brother Bushi. When Aang and his friends are getting ready to clean the lake and ask if Dock would like to help him, he says no thanks but that he will go get his other brother Bushi who he says loves to clean. He changes his hat right in front of Aang and his friends; and when they tell him that they finally caught him he becomes confused and says that he has no idea what they are talking about. Finally he seems to catch on and says that his brother Dock is crazy and pretends to be other people. This only infuriates the group more. His mental state is due to drinking the polluted water.
