A/N: A series where reincarnation is canon, sure why not? Xiang is Tsuna and Wen is his sister Shizuka. Xiang tries to be a voice of reason to the hot-tempered Zuko and his sister. And Wen has no filter, at all. I have no idea where I was going with this one. *sweat drop*

Changing Fate

General Zhao's children were... odd to say the least. Xiang and Wen were both mature for their ages and complete opposites. Wen was a spit fire and was hard to keep in one place. She was unable to fire bend but was on the same level as Azula academically, which lead to the girls often being at each other's throats. Her brother, Xiang, often had to play the mediator. He was more level headed and was a natural at fire bending. Zuko's mother was thrilled that her son had friends that were around his age.

"I'm telling you, Azula is showing all the early signs of being a psychopath!" Wen hissed, sending a glare in the princess's direction. Xiang sighed. "So? What are we supposed to do about it? We're children." Xiang says bluntly, Wen sighed. "I hate being a child. Why can't we skip to being adults?" She complains. "At least there's no mafia in this world." Xiang says, Wen shot him a look. "Our dad is a general, that's almost like having the head of the CEDEF as a father. Except this time around there's a lot of martial arts involved."

"You're just happy to be alive this time around." Wen grinned. "Of course! I mean, there's some drawbacks to having an actual body but I can handle it. Plus Zuko reminds me of the Hibari." She comments, Xiang shivered. "I pray to any god willing to listen that he doesn't become like them. But then again, the gods seem to hate me." He says bluntly. That was the only way he could describe being reborn into this world with his sister.

"At least you're not a mafia boss." Wen says helpfully, getting smack upside the head. "Oi, what was that for?!" She exclaims, Xiang motioned to Azula walking towards them. The only good thing was that Zuko and Azula's friends were behind her as well. "My guess is that you said something stupid, like you always do." Azula says, Wen huffed. "Hey Zuko, I finally convinced Papa to let me use a sword! Wanna duel?" She asks excitedly. While the boy wasn't as obsessed with them as Wen, it was always fun to fight using sticks they found. "Sure!"

Azula scoffed. "Figures that since she can't bend she does something so... barbaric." She says as their siblings laughed happily in the background. Zuko would keep swinging at Wen as she would dance away, a mischievous glint in her eyes. It wasn't anywhere Ty Lee's natural talent but it was still impressive. Xiang shrugged. "Dad said it might come in handy if we didn't have any access to our bending. Besides, I punch people with my fire." He says sheepishly.

The happy times wouldn't last long as both the siblings found out. Zuko had interrupted a war meeting and had his face scared, by his own father. To add insult to injury, Zuko was also banished from the Fire Nation. It was a harsh punishment for a child, Wen and Xiang could both feel their flames trying to attack the perceived threat. "Now I know where Azula got her psychopathy from." Wen growled, the usually jovial girl's eyes narrowed in anger. She had to be physically restrained by her brother so she wouldn't strike the Fire Lord.

"My Lord, she is just a child! She does not know what she is speaking of!" General Zhao hastily defended, not wanting his daughter to have the same fate as the prince. "No, I refuse to be under a man that doesn't value his own blood! Criminals have more honor than you, ya egotistical bastard!" Everyone was surprised as blue flames had formed in her hands. Xiang calmly looked at the Fire Lord. "You might as well banish both of us. Even I can recognize a dictatorship." He says bluntly.

They fled as quickly as they could, coming across Zuko and his uncle Iroh. "It looks like we're going with you!" Wen says cheerfully, hugging a shocked Zuko. "Sis just insulted the Fire Lord's mental health and honor in one breath. On the upside she can finally fire bend." Wen shot him a look, that hadn't been the way she planned to reveal she could fire bend. "Are you nuts?!" Zuko exclaims, Wen shrugged. "It was the only way to be banished with you, there's no way dad would have let us leave. The Fire Lord is a jerk anyways."

Iroh laughed. "Interesting friends you have Zuko. This will certainly be an exciting journey." "Why do you always drag me into trouble?" Xiang groaned, Wen grinned. "Because I'm your adorable little sister and you love me?"

Time Skip: 5 years later

Xiang thought that finding the Avatar would be impossible, if he was still alive then he would be over a hundred years old. Going through puberty on the open seas was awkward, especially for Zuko and Wen. It was like one day the banished prince realized that Wen was a female and started avoiding her. She had to beat some sense into him two weeks later, threatening to toss him overboard if he didn't talk to her. While her bending wasn't fueled entirely by rage like Zuko, she still had a very short temper. Add that time of the month and it was a ticking time bomb.

They hadn't expected much when they were scanning the area surrounding a small Water tribe village. So when they saw a bright light suddenly appear, acting as a beacon, the twins didn't have the same enthusiasm Zuko did. "Even if that IS the avatar, shouldn't he be over a hundred years old?" Wen comments, Iroh raised an eyebrow. "Avatar Kiyoshi lived to be two hundred years old and could still create chasms with her Earth bending. They are not to be underestimated." Iroh says sagely.

They eventually made their way to the small village, populated only by women and children. "Zuko, there's no need to use full force. There's no one here to actually fight." Xiang says, being shoved out of the way as Zuko stepped off their battle ship. "Where's the avatar?" The exiled prince demands, Xiang and Wen sighed. "There is no avatar here, so go on and leave." Katara states, crossing her arms. Wen tuned out Zuko's empty threats he made towards the girl, catching a glimpse of something in the sky. Xiang had spotted it as well. "You wanna tell Zuko the avatar appears to be a kid?" Wen asks bluntly.

Aang had a monk-like appearance and willingly gave himself over to Zuko and their crew. "Wen, Xiang! Keep watch over the prisoner!" Zuko ordered, Xiang rolled his eyes and Wen gave a sarcastic salute. "Honestly, we didn't think you were still alive. Did the original avatar we were looking die or did you find a way to stop the aging process?" Wen asks curiously. "I was kinda frozen for a hundred years." Aang says sheepishly, unable to rub the back of his neck due to his hands being tied. Unlike the rest of the crew, these two soldiers were the only ones not wearing face masks.

"Really? You came out it looking well, we knew this guy that was frozen for seven years and came out scarred. It threw his flames out of whack." Wen comments, Xiang face palmed. "Wen, he's a prisoner." Her twin pointed out. "Excuse me for wanting someone new to talk to. You get tired of the same company after a couple years." Wen huffed as they escorted Aang to a holding room. Without any warning, Wen and Xiang were slammed into the corridor walls by a burst of air.

They watched as the avatar easily escaped from his ropes and proceeded to bend his way out of the ship. "Zuko is not going to be happy." Wen says as the entire ship went on alert, trying to capture the elusive avatar. "When is he ever happy?"
