Daughter to Fire Lord Ozai, Azula is Zuko's 14-year-old younger sister. Azula's a lot like the typical "little Miss Perfect" younger sister, only she's also a deadly Firebender. Azula has always been the favorite of the Fire Lord and everyone else for that matter - everyone except Zuko. Azula excels at fitting her royal role. She is extremely gracious, smooth and put-together. But, she is also cold, calculating, and precise. Zuko will tell you that Azula is "lucky." Things just tend to turn out in her favor.
