The Life of Fire Lord Zuko
Discovering he would have to duel against his own father, Fire Lord Ozai, instead of Admiral Zhao wasn't enough to make Fire Prince Zuko give up. Not on my fic. They fight for a long time. If both father and son utilized nothing more than firebending it could last much longer and Ozai soon noticed that. That's why he decided to use lightning on Zuko. Apparently it seems to have worked but Zuko was just tricking Ozai into lowering his guard so Zuko could give a final blow. Ozai falls unconscious.
Iroh notices his brother doesn't wake up. "The Agni Kai is over. Prince Zuko won." He also notices blood leaking from Ozai's head. "Oh, no! Fire Lord Ozai needs a doctor."
Ozai fractured his skull when he fell from Zuko's blow and it was too late to save him.
"There's nothing more to do. Fire Lord Ozai is dead." The Doctor announces.
"Zuzu, murdering the Fire Lord is treason." Azula says with an evil smirk. "They'll execute you and I'll become Fire Lady Azula."
"Wrong, Princess Azula." Iroh says. "No one can be punished for whatever happens to one's opponent as a result of an Agni Kai. Because Prince Zuko killed Fire Lord Ozai in an Agni Kai he now must succeed him becoming the new Fire Lord."
Both Azula and Zuko drop their jaws at this news. Zuko never believed he would be rewarded instead of punished for killing his father. Azula's friends, Mai and Ty Lee, try to comfort her.
"Azula, I'm quite sure your brother didn't want to kill your father." Ty Lee says.
"Don't you dare to think I don't know that, Ty Lee. I'm upset because Zuzu is the one who'll rise to the throne instead of me." Azula says.
"If that's the case why don't you challenge him for an Agni Kai? You would defeat him with ease." Mai says.
"I have already thought about that but Uncle Iroh would then challenge me for an Agni Kai and take over the throne. He's pro-Zuko and against me." Azula answers.
During Ozai's funeral, a priest makes a last homage to the late Fire Lord.
"We are here because of the passing of Fire Lord Ozai, grandson of Fire Lord Sozin, second son of Fire Lord Azulon, brother of General Iroh the Dragon of the West, husband of Princess Ursa, missing, father of Fire Prince Zuko and Fire Princess Ursa. Because Fire Lord Ozai was killed in an Agni Kai by his son, Fire Prince Zuko is now the new Fire Lord. All hail Fire Lord Zuko." The Fire Priest says.
"Long life to Fire Lord Zuko!!!" Almost everyone at the ceremony says.
Sorry if it was short. I intended this chapter to be a prologue. I've originally posted this fic in a format not allowed by FFN and they removed it because of that. I'll reposted the new versions of the other chapters ASAP.
