Disclaimer: Michael and Bryan own Avatar: Last Airbender. They also own an equally awesome Legend of Korra, which I had debated whether Aizen would have been here or there. I like Korra more then Aang and all, but hey, with the Royal Family, Last Airbender won out by a hair.

October, 87 AG

"Excellent, prince Aizen. Your skills are coming along nicely. Your definitely the prodigy they made you out to be."

Aizen huffed and took deep breaths as the fire bending tutor hired by his dad complimented him. He was learning a new stance and technique used by masters of the element. To many, this technique was a show of many years of mastery, a way to be acknowledged as one of the best. To learn it now would show just how much of a prodigy he was.

But Aizen didn't care about that. To him, this technique just sucked.

He wasn't gonna say it to the master, but the overly-complicated way he had to position his legs just to launch a larger then average fireball just seemed a little pointless. Bigger wasn't always better, after all. He was gonna work on his own style eventually, one that suited him and him alone... mostly. Azula seemed to be showing a preference in flexibility in style just like him. He'd show his little sister some moves when he gets them perfected and see if she likes them. He'd show Zuko too, but he can already tell Zuko's style was going to be something with more power behind it.

Speaking of his siblings, Zuko's training was getting better. He now spouted fire from his hands more then thirty percent of the time! He was proud of him for that. And today, their was no tutor for Azula, but she still doing some minor training in secret despite being told not to. He shook his head at that. Azula could be a little troublemaker when she wanted to be, but he loved her anyway.

Just as he thought about his little sister, the door to the room opened. Aizen turned, expecting to see his dad, who usually checked on his progress every two or three lessons when he could. But it wasn't him. He saw his sister peeking around the room, seeing the Tutor, who was busy writing down some probably important message down on a scroll. She beckoned him over. He looked at the Tutor, shrugged, and exited the room with his sister.

He was about to ask what she wanted, but Azula just tugged on his sleeve and put a finger to her lips. She moved forward, taking him along with her. He didn't resist. If he did it to her so often, he guessed it was fair for her to do the same.

He saw her their rooms soon enough. The three of them each got a giant room and had their own rights to have whatever in it, but since they were still too young they haven't done much. Zuko's was on the left, Azula's on the right, and his in between. Azula and him walked into her room.

"So, what's so special that we had to be sneaky and come to your room?" He asked his little sister.

She turns to him slowly. "Brother, I did something weird, and I want to show you the result."

Aizen looked surprised. "Me first and not dad?"

"I wanted to show my big brother first." She said. Aizen smiled at that.

Azula holds out her palm in front of herself. She breaths slowly. Then in the darkness of the bedroom, there is light.

Light of a Blue flame.

Aizen looks at the blue flame in amazement and shock. The lessons from both his old history Tutors and new teachers never went over any flames that weren't within the orange, yellow, and red variety. It just wasn't something that happened, to have different colored flames. Until now, apparently.

Of course it'd be Azula of all people to break to mold. Shes special like that.

And he voiced his opinion easily, "It's beautiful, Azu. One of a kind."

Azula smiled brightly at her brother. She knew showing him first was the right thing to do. She also knew what would have happened if she had shown anyone else first. Dad would have been pleased, but for his own benefit of showing her off and getting recognition. Mom would have been afraid. Zuko would have only showed jealousy. But not Aizen. He truly just cared for her.

"Do you mind if I try something?" Aizen suddenly asked her.

"What do you want to try?" She looked into her brother's eyes. He just winked.

"Just trust me, alright?" He put his hands near the blue flames, closing his eyes.

Azula's hands warmed up to a slightly uncomfortable level, and for a split second she thought to pull them away. But her brother said to trust him. So she would. She glanced at her brother, whose face was in concentration. She felt the flame grow fiercer and larger. Her brother had a bead of sweat appear on his face.

Just as she was about to question him again, she saw the flames start changing colors again, from green to red to pink to purple and finally... to White.

Azula's wonder increased tenfold at the new flame in her hand. She felt some of her inner chi being drained, but not much. Her eyes just stared at the flame. It was... beautiful. And powerful.

Aizen opened his eyes to look at the flame in front of him and, seeing the White flame, he smiled... then fell to the ground unconscious.

Azula heard the 'thud', looking to see her brother hit the ground. This shocked her enough to have the White flame disperse. "B-Brother!"

She tried to shake him awake, but he was truly out of it. "H-Help...!"

The shout echoed throughout the room, but nothing happened. Panicking, Azula opens the door out her room, calling for help. It was the first time she ever cried for help. It was also the first (and only) time a servant ever saw the young princess have tears in her eyes.

The Next Day

Azula, Ozai, Ursa, and a doctor stood in Aizen's room around the young man.

"He's fine, it was just an over exhaustion of chi. Though usually with this level of depletion your son either had a secret Agni Kai to the death or had been bending for multiple hours straight without stop." The doctor stated. Azula and Ursa give a sigh in relief at hearing Aizen was alright. Ozai, however, was focused on the problem at hand. Namely, how his son got in that condition in the first place.

"The Tutor made sure not to exhaust my son to such an extreme. I would have had his head on a stake somewhere in the colonies." Not an exaggeration at all. He turned to Azula. "Does this have to do with those Blue flames you revealed to me earlier?"

Azula flinched at the tone of her father. She wasn't used to being on the receiving end of her father's harsh words. That was usually reserved for Zuko. "H-He said it was amazing, father, but he wanted to try something. He put his hands to mine and put his own chi into the fire and... it went multiple colors before becoming pure White."

"White?" The Blue fire surprised him to begin with, but to have his son help create a pure White flame?

"It... It felt very powerful. It tugged on my chi a bit, but I think it was Aizen who mainly put his chi in. After holding it for a few seconds he just... collapsed!" She couldn't help but increase her volume at the end. She hated that she left her brother so weak and defenseless like that.

"So strong that it ate at his chi that quickly?" Granted, his son was still just three, but the drain of such a powerful flame was astounding. If the Blue flame was more powerful then a normal flame -which he had no doubt in believing it did- then the White one must be even stronger, perhaps even one of the strongest fire techniques to ever be made, short of lightning bending itself.

"A discovery like this... These new flames will probably have your children go down in history books, Prince Ozai." The doctor commented.

"My children would have left a mark on history regardless." Ozai stated with ease. "This will just make their mark larger to see."

Three Days later, Sozin Academy (Bonus)

"So why did you get out of school again?"

"Oh, you know, just trying to leave a mark in the history books."

"... Do I even want to know?"

"Pretty sure you do. Oh, and my little sister makes Blue Fire now!"

"And how would this interest me?"

"... Because it's never been done before? And it's also ANOTHER thing that'll probably go down in history?"

"What's your point?"

"Your trying to be boring again, Mai."

"If I'm so boring, why do you continue to hang out with me?"

"Because who else would if I didn't?" BONK! "OW!"

"You were saying, Aizen?"

"... Since when did you start carrying chalk to throw at me?!"
