That would be "The FireBending Masters". the firebending masters when aang and zuko learn firebending (well zuko learns the propper way to use it) btw that episode is one of my favourte episodes
Aang accidentally burns Katara with his firebending in the book three episode "The Firebending Masters" (Season 3, Episode 13) of Avatar: The Last Airbender.
They were the dragons known as The Firebending Masters
Airbending,Firebending,WaterBending,EarthBending,Metalbending,lightningbending,sandbending,
Avatar The Last Airbender - 2005 Sozin's Comet The Old Masters SUSPENDED was released on: USA: 30 November 2008
He is a fire bender. Throughout the first 2.5 books, he uses anger to power his fire. It is not until he learns how to firebend form the firebending masters that he learns to bend fire from a different source.
That could be a lot of things, but I would say when Avatar Aang took away Firelord Sozin's firebending and finally ended the great war.
The episode where Aang attends a Fire Nation school is "The Headband" from Book 3: Fire. It is Episode 42.
