Poon

"fire"

- You used to be the pride of the Fire Nation: Our top general, the Dragon of the West. Now, look at you. Look what you've become.

Warden Poon was the warden of the Capital City Prison near the Fire Nation Capital. He was known to be a tough, insulting warden who bore little to no respect for the criminals under his watch. He especially despised General Iroh because he was a traitor to the Fire Nation. He saw Iroh as nothing more than a weak, washed-up, lazy, and wretched old man content to grovel in his own filth. Warden Poon spent most of his days walking up and down the prison corridors and verbally assaulted the prisoners in order to break their spirits.

History
Before and during the invasion, he harassed Iroh because of the latter's military disgrace at Ba Sing Se. He was also confident that Iroh would never escape the prison and was doomed to rot in his cell, never realizing that, the entire time, Iroh had been physically conditioning himself without Poon's knowledge. During the Day of Black Sun, Iroh, having regained his previous fitness, succeeded in breaking himself out of the prison. Evidently, Poon and Iroh fought each other almost immediately after Iroh broke out, as Zuko found Poon lying on the floor, dazed and unable to stand. Poon told Zuko upon arrival that he had never seen anything like it, and that Iroh was like a "one man army."

It is unknown if Poon retained his position as warden with the end of the War and the rise of Fire Lord Zuko.
