Avatar AU in which AZULA is the one banished instead of Zuko. The reason? She speaks up at the war council but not to oppose the general’s plans but to suggest a better military strategy. For her arrogance, she is challenged to an Agni Kai. When she sees its her father she’s set to duel, she doesn’t back on and battles her hardest but an 11 year old girl - even a firebending prodigy - can’t hope to defeat the Fire Lord. Ozai banishes Azula and Azula sets out on a quest to find the Avatar to display her strength and ruthlessness.
Zuko remains at the Fire Nation palace and though he is set to claim his birthright and inherit the throne, Ozai has never kept it hidden how he regrets Azula’s banishment and the subsequent loss of his strongest child. Neglected and alone, Zuko finds solace in his Uncle, who has always believed in him, who improves his skills with careful tutelage.
Upon her fifteenth birthday, Mai sets out into the world, first to find Ty Lee and then together, they search for Azula to aid her in her mission of capturing the Avatar.
Abandoned by his girlfriend, Zuko realizes what they mean to do and aims to stop them. He and Iroh leave, traveling under the cover of night. Their mission? To find the Avatar and protect him, all the while undermining Azula’s plans. If she can capture the Avatar, the Fire Lord would realize what a valuable asset she is and set Zuko aside in favor of the Princess and they can’t have that.
