Headmaster

"fire"

- That's what any mother would say, ma'am. Nonetheless, you're forewarned. If he acts up one more time, I'll have him sent to reform school... by which I mean the coal mines. Are we clear?

The Headmaster is the senior teacher at the Fire Nation School in which Aang enrolled after Team Avatar's arrival in the Fire Nation. He has one of the most important jobs in the Fire Nation – or at least he thinks so – maintaining order and discipline so that young Fire Nation minds can be properly molded.

History
Before he was headmaster, he was a drill sergeant in the army and much of what he learned there, he uses today. Any disorderly child must be immediately dealt with, in other words, sent to the coal mines for "rehabilitation." Nothing makes him happier than when a father talks about punishing an unruly child.

After Aang bested fellow-student Hide without touching him, the Headmaster came to the Courtyard. When he saw Hide lying on the ground, he believed Aang beat him up and he informed Aang that he was to be punished with a parent-teacher conference. The Headmaster was tricked into believing that Sokka and Katara (Mr. and Mrs. Fire) were his parents after they dressed up. The Headmaster was then informed by Hide that Aang was throwing a secret dance party in his cave. When he arrived, it was impossible for him to catch the real Aang because all the students dressed up like him to help Aang escape. The plan worked, and Aang and his gang escaped.

Personality
The Headmaster is a rigid, extremely strict man who expects nothing less than perfect behavior from the students at the Fire Nation school. A seemingly ruthless and crochety person, he enjoys nothing more than dealing out punishments or seeing a child being chastised by a parent. He is uptight and does not harbor much sympathy for others.
