Chan was the admiral of the Fire Navy's Eastern Fleet. He was infamous among many Fire Nation naval officers for his lousy communication skills. He was the father of Chan and had a vacation home on Ember Island. The admiral was later mentioned when his son, Chan, said that his father was an admiral.
After the fall of Ba Sing Se, ChiefHakoda joined forces with Team Avatar and some other Water Tribe warriors. While disguised as a Fire Nation soldier, he ran into a Fire Navy officer, who told him that Chan should have informed him that Hakoda's vessel, secretly carrying AvatarAang, was sending supplies back home to the Fire Nation. The officer later found out that Chan had been on leave for two months on Ember Island and therefore had no knowledge of the vessel's true intent.
