Tho

"water"

- Set my lines by the river bed! Caught ten fish and I killed 'em dead! Cut 'em and gut 'em and I tossed the heads in the water to keep them catgators fed.

Tho lived in the Earth Kingdom's Foggy Swamp Tribe with his friends, Due and Huu, as well as the rest of his tribe.

Tho was a simple man who loved living in the swamp. He was one of the smarter members of his tribe, and was usually the one instructing Due and the others on what to do. Like Due, he cared for his tribe and wanted what was best for everyone. Tho was a hospitable person and was more than happy to have a few visitors over for dinner.

History
When Momo and Appa were separated from Aang, Katara, and Sokka, they encountered Tho, who was a little short and chubby, and Due, who began hunting them down. Aang found Appa and Momo, thus preventing Tho and Due from eating them. Despite having just been attacked by the Avatar, the tribesmen more than happy to find fellow waterbenders outside of the swamp in Aang and Katara. They later invited the team to dinner at a small settlement within the swamp.

Tho, Due, and Huu later helped with the initial land stage of the Invasion of the Fire Nation, but remained behind when the invasion force started scaling the volcano. When the eclipse ended, the Fire Nation deployed its airships. The airships proceeded to the beach to destroy the submarines. The three were last seen at the beach, protecting in vain the subs from being destroyed. A bomb blew them down, but they survived. Tho was held in a Fire Nation prison along with the other warriors. However, at the end of the Hundred Year War, he was released along with the rest of the members of the invasion, and, alongside his fellow tribesmen and women, was present at the coronation of Fire Lord Zuko.
