Disclaimer: I don't own Azula or any other character that might appear in this story. Unless I specifically say so. So there.
Ever since I was a child, I knew it would be me who would take the throne, instead of my weak, pathetic brother. It was obvious really. I was the fire-bending prodigy, the smart one, the favored one. Father loved me, and if mother was not as enamored of me as she was my brother, who cared? Father would be the Fire Lord, not mother. Father was the one who truly mattered.
When grandfather Azulon died and named father as the new Fire Lord, I knew it would be smooth sailing. There had been a few tense moments there, when I was sure grandfather would name his Royal Tea Loving Majesty as the new ruler, but I should not have worried. Father had everything under control. And not only that, mother mysteriously "left", and brother was without a friend. Everything was going my way.
You see, father's plan was very elaborate. Even I did not know all of it. There were double crosses, secret meetings, deception, bribery; anything you could think of that was crooked, you could bet it was involved. I could not have done better myself, and that's saying something. And right in the middle, the thing that held it all together, was the comet. Sozin's comet. Its name came from my great-grandfather, Fire Lord Sozin. He used the power of the comet to start the war against the other pathetic nations. The comet only comes every hundred years, so the Fire Nation had a long wait before we could finish the war once and for all, but it was worth it. One nation has been exterminated, and the others are ready to fall. And my brother was exiled, leaving the path to the throne wide open for yours truly. My father might think that he would be the one to finish it all, but there are certain, surprises, he knows nothing about. I was not made to sit in the background, and I will not settle for second best. I will be Fire Lord, no matter the cost.
Now, you might be thinking, how does she hope to accomplish such a goal when such an enemy as the Avatar stands in her way? Well, since you are so interested, I will tell you. The Avatar is weak. He may have potential for greatness, but he will never achieve it. He hides behind his companions, letting them save him. I have not yet faced him in battle, but I am confident that with a few choice cohorts I will be able to defeat both him and his posse. Besides that, he has a weakness. He is attached to many different individuals, especially a certain Water Tribe girl he travels with. Threaten any of these individuals' safety, and he lets himself be captured. My pitiful brother let him escape numerous times, but I am certain I will have no such difficulties. At the risk of sounding cocky, he is no match for me.
