Due

"water"

- C'mon now, fellas. Just a little closer. Nice and easy. Nothing to worry about. We just fixin' to eat ya.

Due was a waterbender from the Foggy Swamp Tribe in the Earth Kingdom. He lived in the swamp with his friends and fellow tribesmen, Tho and Huu, as well as the rest of his tribe.

Due did not seem to be particularly intelligent, and usually let Tho do most of the thinking for him. He seemed to deeply value family ties and relationships, and considered himself and Katara to be "kin" because they were both waterbenders. He even called his catgator, Slim, a member of the family. In general, he was slow-witted but very friendly and worked hard alongside his friends and family to keep them happy and well-fed.

History
The ancestors of the Foggy Swamp Tribe migrated from the Southern Water Tribe thousands of years ago and found the Foggy Swamp. Because of all the water in the swamp, the waterbenders felt at home and decided to stay. The swamp folk were often considered strange because of what they ate, such as possum chicken and giant bugs, the way they dressed in leaves, and the way they spoke.

While Momo and Appa were separated from Aang, Katara, and Sokka, they were being hunted by Tho, who was a little short and chubby, and Due, who was very tall and skinny. Aang found Appa and Momo and stopped Tho and Due, who were more than happy to find fellow waterbenders outside of the swamp in Aang and Katara. Due, Tho, and Huu then brought the team to their camp to share a meal.

Tho, Due, and Huu helped with the initial land stage of the invasion, but remained behind when they started scaling the volcano. When the eclipse ended, the Fire Nation revealed its airships, which proceeded to the beach to destroy the submarines. The three were last seen protecting the subs from being destroyed, but their efforts proved to be in vain. Following the imprisonment of all the adult invaders, Due was in a Fire Nation prison with all the other warriors, but he was released along with the rest at the end of the War.

Along with Tho, he was last seen in attendance at Fire Lord Zuko's coronation.
