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 was the senior teacher at a Fire Nation school in which Aang enrolled after Team Avatar's arrival in the Fire Nation. He had, at least according to him, one of the most important jobs in the Fire Nation, as he maintained order and discipline so that young Fire Nation minds could be properly molded.

History
Before he was a Headmaster, he was a drill sergeant in the army. Much of what he learned there, he used as a teacher. Any disorderly child had to be immediately dealt with; in other words, they were sent to the coal mines for "rehabilitation." Nothing made him happier than when a father talked about punishing an unruly child.

Just after Aang, who was using the false name of Kuzon at the time, had bested his fellow student Hide without touching him, the Headmaster came to the courtyard. When he noticed his star pupil lying prone on the ground, he immediately assumed that Aang had beat up Hide, and he duly informed the "troublemaker" that he was to be punished with a parent-teacher conference after school. The Headmaster was tricked into believing that Sokka and Katara, having assumed the names of Mr. Wang Fire and Mrs. Sapphire Fire and donned adult clothing, were Aang's parents.

Later, Hide told the Headmaster that Aang was throwing a secret dance party in a nearby cave. Shortly after, the Headmaster, along with several truant officers, arrived. He attempted to catch Aang; however, all the students used their sashes as headbands - similar to the one Aang was wearing - in order to help the young Avatar escape. The plan worked, and Aang and his gang escaped.

Personality
The headmaster was a rigid and extremely strict man who expected perfect behavior from the students at the Fire Nation school. A seemingly ruthless and crotchety person, he enjoyed nothing more than dealing out punishments or seeing a child being chastised by a parent. He was uptight and did not harbor much sympathy for others.
