Azula (Avatar The Last Airbender)

The daughter of the fire nation

Azula was the princess of the fire nation in the manga and cartoon Avatar The Last Airbender. She is a mentally unstable young woman who grew up with her father, believing that her mother loved her more than her brother Zuko. She trained tirelessly to become the best fire bender but never received the affection she wanted. She is also cruel and ruthless but a fine strategist who made her a formidable enemy for Avatar Aang and his group. When she was defeated by her half-brother Zuko and betrayed by her friends, she had to be interned. She escaped and tried again to regain power, but to no avail. She disappeared and was not captured.
