Azula is the princess of the Fire Nation, daughter of Fire Lord Ozai and Princess Ursa, younger sister of Zuko, older half-sister of Kiyi, girlfriend of Bowser Jr., and one of the main antagonists of the IG-88's Adventures Series. She was a key adversary of Team Avatar, chasing Avatar Aang and her banished brother far across the Earth Kingdom accompanied by her two best friends Mai and Ty Lee.

A firebending prodigy, Azula is sadistic, manipulative, and obsessed with power. She was a skilled strategist who orchestrated the coup over the Earth Kingdom capital Ba Sing Se, and halted the invasion on the Day Of The Black Sun.

Azula harbored deep mental instabilities, believing her mother loved Zuko more th an her. Raised by her father in an environment without her mother, Azula had to be nothing less than perfect in her father's eyes just to earn any affection from him. After the betrayal of her two closest friends Mai and Ty Lee, these instabilities were brought up to the surface. Upon the arrival of Sozin's Comet, Azula was soon to be crowned FIre Lord, but her defeat at the hands of brother Zuko and Katara caused her to suffer a complete mental breakdown.

Following this, she was put in a mental health institution to recover, but Bowser soon freed her and she joined The Horde Of Darkness to gain revenge on Team Avatar. She is voiced by Grey DeLisle.
