It all started with an act of kindness. Senshi was an orphan in the Fire Nation Capital. He was nothing special. Just your everyday Fire Nation orphan.

It was on one of her walks that the Fire Lords wife, Ursa, noticed the young boy attempting to steal a money purse from one of the patrons at a restaurant. He couldn't have been much older than her own son, Zuko, whom was seven. He had long silver hair, all in a mess. His eyes were yellow and wolf-like, and his clothes were just rags. The boy was caught in the act and thrown out the door by the owner.

"This is the last time, you little punk. Bother my customers again, and I'm calling the guards!" The annoyed man shouted.

The boy sat up with a huge grin on his face as he watched the man go back inside. Checking to make sure that no one was watching, the boy pulled out a large piece of venison that he must have stolen from the shop when the owner wasn't looking. Sneaky little thief. Against her better judgment, Ursa followed the boy down an alley, and ended up outside of an old abandoned building. The boy made his way inside, and Ursa looked through one of the cracks in the boarded window. She had expected to eat the food himself, but, to her surprise, he was tearing pieces of the venison to feed to a small puppy that was curling up next to him.

"There you go, buddy. I'm sorry, but that's all I could get." The boy said to the starving pup.

Ursa was heart broken. Here was this young boy, whom was in a worse position than most, and he was more worried about his little dog friend than himself. It was truly an inspiring scene. The kind wife of the Fire Lord couldn't just sit there. She made her way into the house and confronted the boy. When he noticed her, he scrambled, picking up the puppy quickly and climbing up into the rafters.

"What do you want?" The boy asked. "I'm not going back to the orphanage. They're evil."

"I'm not here to take you anywhere." Ursa spoke kindly.

The boy seemed skeptical. "Really?"

Ursa laughed. "Really."

"Promise?"

"I promise."

The boy gave a sigh of relief and dropped down in front of the kind woman. He smiled at her and continued to feed his small companion. Ursa sat down beside the bow and watched him.

"Where are your parents?" She asked him.

"Dunno." Was his answer.

"Did they leave you here?" She tried again.

"I never met them."

Ursa was taken aback. This boy has been alone his entire life? She had to do something about this.

"Would you like a mother?" She asked him.

"No, not really." He answered her. Ursa sweat dropped at that statement but looked up when she heard the boy continue talking.

"On the other hand, it would be nice to belong somewhere." He said longingly.

That was the final straw. A small tear found it's way moving down her cheek. Ursa grabbed the boy into a hug that he was not expecting. After a moment, Ursa let go of the boy.

"You're coming home with me." She said in her 'Mother Voice.' She could tell that the boy was going to argue, but he hung his head in defeat.

"Can Kiba come with me?" The boy asked, motioning to the dog in his lap.

Ursa smiled and nodded. He's still worried about his little friend. Zuko's going to love having a brother

"How old are you?" Ursa asked.

"Eight." Was his reply. A year older than Zuko. Azula's only five, so she probably wouldn't mind having him hang around.

"Okay, come on, we're going home now." Said Urza.

The boy resigned himself to following his new "Mother."

They arrived at at the Fire Lords palace and the boys eyes widened.

"Why are we here?" He asked in astonishment.

"I live here." Ursa told him. "And now, so do you."

The youths jaw dropped as he considered how lucky he was... Until he met the Fire Lord.

The two were approaching the Fire Lords throne room. The could hear shouting coming from the other side.

"What do you mean you still can't find the Avatar!?" Came the angry voice. "How hard can it be to find one person!?"

Ursa sighed, and entered the room with the young boy in tow.

Fire Lord Ozai glared in her direction, but his features instantly softened at the sight of his beloved wife. Then he spotted the boy.

"Ursa, who is that?" Ozai asked.

"Our newest son, dear. I found him on the street. I'm adopting him." Came her reply.

Ozai looked at the boy for a moment, before giving a light smile.

"What is your name, young one?" Ozai asked.

"Senshi." Senshi answered nervously. Ozai nodded.

"A strong name you have there, Senshi. I approve." Ozai looked to the soldier that he was yelling at only moments before. "Fetch my children. Bring them to meet their new brother."

The soldier bowed and left the room. Moments later, two kids were ushered into the room by the soldier. One was a boy about the same age as Senshi, and the other was a slightly younger looking girl.

"Father?" The boy asked, looking to Senshi with curiosity. "Who is this?"

"This is Senshi." The Fire Lord answered. "Your new brother." Ozai looked at Senshi. "These are your new siblings, Zuko and Azula." Ozai motioned to the two in turn.

Senshi bowed to them. "It is a pleasure to make your acquaintance. I hope that we can become friends."

Azula smiled at the overly polite boy. Zuko bowed back, bound by tradition. Suddenly, there was the sound of whining coming from Senshi's shirt.

"What's that?" Asked Zuko.

"Kiba, my friend." Said Senshi, pulling a small wolf pup from his shirt.

Ozai snapped his fingers. A servant appeared a moment later.

"Take My new son's friend to his new quarters." The servant bowed and obeyed the command.

"Can you bend?" Asked Azula, after the servant left with the dog.

"Bend?" Senshi was perplexed.

Azula shot her hand to one of the un lit torches, and blue fire shot out to it.

"Oh, that. Yes, I think so." He answered.

"Show me." Asked the girl, content with the thought that she would be superior to yet another bender.

"O-okay" The boy answered nervously. He took a careful step forward and put his fist out, as if her were slowly punching the air. Instead of the common flash of orange and yellow, an unnaturally dark burst of blood-red flames shot from his fist, destroying the candle completely.

Senshi quickly bowed as low as he could with his forehead touching the ground. He feared that he had ruined his chance to belong.

"Please forgive me!" He begged.

Azula and Zuko were frozen. Crimson flames? What?

Ozai, on the other hand, was happy as could be. 'A unique flame! This is perfect.' He thought. He cleared his voice and looked at the begging boy.

"Stand, Prince Senshi. Begging is not proper for someone of your class."

Senshi's head snapped up so fast, Zuko thought he would have broken his neck.

"I-I can stay?" The orphan asked. Ozai smiled warmly at him, and nodded.

"You will be given proper tutoring, in both fire-bending, and swordsmanship." Said Ozai "At the age of twelve, you will be appointed the personal bodyguard of my daughter. Understood?" The boy nodded enthusiastically. "Good. Azula, Zuko. Take your new sibling and get him cleaned up. He looks very un-prince like."

"Come "brothers." We must not disobey Father." Said Azula, grabbing both of the boys by the wrists and dragging them out of the room, while Ozai and Ursa laughed.

:First, you must shower. You stink." Said Azula. "I assume you can handle this part, Zuzu. I would, but I'm not sure I would want to." Both boys blushed at the comment, Senshi in embarrassment, and Zuko in annoyance.

"Yes, sister." Grumbled Zuko as they reached the showers.

"I will wait here." Azula told them, leaning against the wall.

They emerged about twenty minutes later, and Azula had to admit how handsome Senshi was, with all the grime and dirt cleaned from him.

"Next, I plan on fixing that unruly hair of yours." Azula grabbed Senshi's wrist. "Beautiful hair such as ours should be taken care of." Senshi bowed.

"Yes, Princess." Said the boy. Azula blushed, ever so slightly at the comment. She yanked the boy down the hall. Zuko couldn't help but laugh. Finally, Zuko can have a non-female friend.

In Azula's room, the said princess was attempting to run her brush through a large rats nest in Senshi's hair, while the boy was trying not to yell in pain. Azula smacked him in the back of the head.

"Stop fidgeting." Said the princess.

"Well, it hurts." Pouted the new prince. "Quit pulling so hard!"

This went on for thirty minutes before Azula finally managed to get his hair in shape. She had it tied in a long pony-tail, much lower than Zuko's. She couldn't bare to cut off his beautiful locks.

It was ten at night, and Senshi found himself lying in a large bed with Kiba sleeping next to him. He went over the days events. So much has changed for him in so little time. Senshi's thoughts soon went to Azula. He smiled.

"I think I'm going to like it here." Senshi whispered to himself.

...

A/N: That's that!

The next chapter will be a time skip of four years.

Oh, and incase you're wondering, Senshi means "Warrior."

CYA LATER!
