During Firelord Ozai's reign as Firelord he had many people who went against him who resided within the Water Tribes and the Earth Kingdom and many of the colonies that resided everywhere. It is likely that Ozai would have had loyal servants and many supporters who went with his regime to make the Fire Nation "Superior".
So what happened to them after Prince Zuko became Firelord when the Hundred Year War was over? Is there any evidence to say that he did/didn't have supporters?
Answers are appreciated. :)
