Azula is the princess of the Fire Nation during Avatar: The Last Airbender. She was one of the most powerful antagonist in the series and often caused distress not only towards Team Avatar but also her brother, Zuko. She is the youngest child of Fire Lord Ozai and Princess Ursa and her father's favourite child. Azula seemed to dislike her mother or simply had netural emotion towards are and was very aware that her mother thinks she is monsterous. Azula is named after her grandfather, Fire Lord Azulon, that shows she could of have instantly been her father's favourite when she was born.
Azula is an extremely skilled firebender and is capable of conducting lightning with ease, being taught mostly from her father. Something very noticable about her firebending is that it is blue. Other firebenders fires are typically red, orange and yellow colours.
On the day of Sozin's Comet she was to be crowned the Fire Lord (her father crowned himself as the Phoenix King) and was challenged to an Agni Kai by her banished brother, Prince Zuko. She confidently accepted and eventually lost. She suffered a huge mental breakdown afterwards, though, she often showed slight flaws in her mental stability throughout the series, especially when her friends Mai and Ty Lee betrayed her.
Azula is a cold hearted woman who strives for success and perfection. She shows no mercy or pity on those she sees to be inferior and she completely lacks sympathy and empathy towards anyone, including her friends and family. She strongly believes that having domination and power makes one strong. Azula is very confident in herself and believes that she has the devine rights to rule, she says that she had this since birth. She enjoys others being in physical or emotional pain and she is extremely manipulative ever since she was young.
