Princess Azula is a fictional character voiced by Grey DeLisle in the animated television series Avatar: The Last Airbender.

Azula is Zuko's younger sister, first seen in the audience at Zuko's Agni Kai against his father. She is named for her grandfather, Ozai's father, Fire Lord Azulon.

Mai

Mai is a cold, calm, and reserved young woman, and an old schoolmate and longtime friend of Azula and Ty Lee. She is an extremely skilled warrior in the art of Shuriken-jutsu, her primary weapon being small, knives that are spring-loaded in holsters on her wrists and ankles. She also employs a variety of other throwing weapons with deadly accuracy and has proven herself capable of being a powerful enemy to both the avatar and Zuko.

Ty-lee

Ty Lee is a cheerful young Fire Nation acrobat/gymnast, the daughter of a nobleman, who grew up at the Fire Nation royal court and attended the Royal Fire Academy for Girls with her friends, Azula and Mai. Ty Lee is a formidable hand-to-hand combatant, utilizing a martial art attacking pressure points on the human body. This was proven when she was easily able to take down an elite platoon of Earthbenders alone. By striking a bender's pressure points she is able to disrupt the victim's chi flow and temporarily remove their ability to bend.
