(Chapter 1)

(Southern Water tribe, 167 AG)

In the icy fields two figures stood in the center facing one another. The taller of the two was male with black hair curly hair, light olive skin and cornflower blue eyes. He wore standard deep blue hooded anorak with white fur on the hood and shoulders with loose darker blue pants and brown boots. The other was female, a few inches shorter, with brown skin, cyan eyes and deep brown hair pulled up in traditional water tribe hair style.

The boy stood in a more defensive stance and focused look in his eyes while the girl held a more aggressive stance and confident gleam in her eyes.

Neither of them were willing to make of move until the other did first, years of practicing with one another making them wary of what the other could do, but in the end the water tribe girl gave in to the impulse and raised her hand causing a ball of water to rise from the floor and float in front of her. She froze the body sized ball of water and sent it flying toward her opponent.

Narrowing his eyes, the boy swiftly caught the boulder of ice in his water bending grasp and spun while returning the boulder back into a state of water and sent it flying back at the his opponent. But he didn't stop there.

When he saw his opponent duck under the harsh wave of water, he darted forward, swiftly, grabbing water from the ground and using it as a whip. He swung.

"Ha!" his opponent taunted before launching herself into the air and looked down at him as he stared up. "Didn't think I saw that, did you, Kaiza?" she asked cockily.

His lips twitched into a smirk and she began to descend to the ground. "I knew you saw, but it's what you missed that decides this match, Korra." He stated causing confusion to grace his opponent's, Korra, face. Her eyes widened when she noticed that the ground she was descending towards shifted to stalagmite made of ice.

Panicking, she gasped and then punched a blast of fire at the ice, immediately melting the ice into water. She sighed when she landed and kneels, relieved, before glaring up at Kaiza, who was already on the defense again.

Water wrapped around him in a ring before eight tentacles grew from the ring and wiggled in the air around him, ready for anything that could be thrown at him. "Come on, Avatar, if you feel like you need fire to beat me, bring it, you can have the handicap." He taunted knowing that would stop the Avatar from using her other elements.

Korra frowned, easily falling for his trap, and glared. "I don't need anything else to beat you!" she sneered before sending a ferocious wave of water at him.

Launching himself over the wave, Kaiza used his water whip to wrap around a pole and quickly pull himself to the ground when Korra sent another wave of water at him while mid-air. He narrowed his eyes before sprinting toward her, once close her, he performed a somersault, avoiding a blast of ice, and landed behind the Avatar.

Closely behind the Avatar.

Korra raised a wall of ice to put some separation between them but Kaiza turned the wall to water and launched him attack.

By gaining Korra's attention and turning her back, she didn't notice that the octopus formed by Kaiza never dropped but instead waited for its manipulator to bend it. Three tentacles shot forward and wrapped around the hand that Korra brought up to send another attack.

The water dropped to the ground when Korra gasped and lost concentration at the unexpected attack. Grunting, she narrowed her eyes and turned kicking up and watched as a wall of ice rose, cutting through tentacle thus releasing her.

She turned back to Kaiza, who fell back into his defensive form while dropping his control on the octopus form. She shot forward and they began a close range fight. She kicked a wave of water at him only for Kaiza to bend back, then shot an ice boulder at him causing him to raise a wall of ice blocking it but the ice boulder destroyed it upon impact also.

Kaiza grunted as he skidded back from the collision and destruction of his defenses. He glared up at Korra, who smirked cockily, before raising a large body of water high into the air. Kaiza frowned. "Damn it." He said as spears of ice began to rain down toward him. Thinking quickly, he turned water into mist and used it as cover.

The spears of ice rained down into the mist cloud but Korra couldn't tell if they it their target or not. Squinting, she tried to peer through the smoke to spot her opponent but as it began to clear, she saw that he was no longer there. "What?" her eyes widened as she felt hands grapple around her ankles. "Whoa!" she gasped before she was drug down into the ice, the neck and down now trapped the ground of ice. She struggled to get free but it was futile.

In front of her, a hand shot forward and landed on the ice before her before Kaiza's head appeared and he pulled himself from the ice. He smiled haughtily down at her. "Whelp, looks like I win, Kor." He teased crossing his arms over his chest.

Cyan eyes glared up at him. "I demand a rematch!" she exclaimed.

"Now, Korra, he won this battle." They heard and turned their heads to see an elder woman walking down the stairs toward them.

Korra pouted and turned her head away from the elder. "You're only saying that because you're afraid I'll pound your grandson into the ground if I get my rematch." She claimed.

"Sore loser." Kai snorted before turning to his grandmother, Katara, and smiled slyly. "So, what do you think, Grams?" he questioned. "I've gotten a lot better, right?"

Katara chuckled as she wave her hand. "Whoa!" Korra exclaimed as she was spat from the ground and on her stomach. "You sure have, Kai, you too Korra, you've both come a long way." She told them.

Kaiza offered Korra his hand, which she promptly slapped away before tackling him to the floor. She pinned him to the ground. "I would have won if you weren't always dodging me." She claimed. "I would have crushed you into the glacier!"

Rolling his eyes, Kai smiled. "If you have a crush on me, Korra, just say so." He jested earning a furious blush across the Avatar's face and punch to the chest.

"I do not have a crush on you!" she raged, a small burst of fire flying from her mouth, though it disappeared too quickly for it to have done any damage to Kaiza, who didn't flinch at his friend's temper.

"This position we're in would imply different."

Korra quickly hopped up and glared down at him. "Why you-you-you…" she was at a loss for words.

"What an extensive vocabulary you have, Korra!" Kaiza chuckled then grunted when he was hit in the face with a snowball. He wiped his eyes in time to catch Korra's retreating back. "Love you too, sweetheart!" he called.

Katara, who watched silently, shook her head with a chuckle earning her grandson's attention. "The two of you will be the death of one another, I think it's a good thing that the Chief disbanded your arranged marriage." She said holding her hand out for Kaiza to grab.

He took it and stood from the floor. "I think it's a dying shame." He smiled. Though he had no romantic feeling for Korra, as he was only thirteen and she fourteen but the Chief thought it would be good to arrange it soon, though after two years changed his mind under Korra's temper and her Avatar training. "Anyways, so she's already done with waterbendeing, earth will be next right?"

He knew that Korra was exceptionally good as a water bender, she long since "mastered" the art of bending water under the tutelage of his grandmother. He knew that she had other elements to master, being the Avatar and all.

"Yes, she'll be moving onto earth while you and I will continue on with our training, which will only get tougher from here on out." Katara stated though her grandmotherly smile never dropped.

"I expect nothing less." Kaiza snorted. "Though if dodging ice glaciers and dodging boulders of ice thrown by you counts as easy to you, I quake in fear at what you think is hard." He teased.

Katara laughed and ruffled his hair. She eyed her grandson, more than anything he resembled his father with his mother's eyes. He was the only one of her grandchildren to inherit her ability to bend water and not only that; he had a real knack for it. He reminded her of herself back then.

Watching as Kaiza fixed his ruffled hair, she placed a hand on his back and began to lead him away from the field. "Let's go back home, your brothers arrived a couple hours ago and I'm sure your mother can't wait to see you as you've been out here all morning."

Kaiza only shrugged but frowned at the thought of all his siblings being in one place. He inwardly groaned at the prospect. Being the second youngest amongst five kids wasn't all it was cracked up to be, sure he loved his siblings very much but despite that they were very annoying.

Luckily for him it wasn't all of his siblings that will be there. It was just his youngest and one of his older brothers, Lee and Hakoda, respectively.

Hakoda was a police officer in Republic City and he was an earth bender, granted to him by their paternal grandfather's Earth Kingdom heritage. He was a very laid back guy, never really took anything serious and was a go with the flow kind of guy, which struck Kaiza strange for a earth bender but his brother was always like that. He couldn't remember the last time he'd seen his older brother upset about anything.

And his younger siblings, Lee, wasn't a bender but he was energetic, resourceful and clever. Kaiza liked to consider the little freak a mad mechanist as he was always messing around with things he shouldn't trying to build something new or playing pranks on everyone he comes in contact with. He and Lee butted his a lot more than normal as the mechanist liked to use him as practice for his pranks.

Groaning lowly, he turned to his grandmother with pleading eyes. "Can we please skip this dinner and just continue to train?" he pleaded.

Laughing, Katara patted his head affectionately. "Now, Kai, don't be that way, they're your siblings."

Kaiza gave her a somber look. "Grams, I'm sorry to tell you, but I have a speculation I may be adopted."

Katara shook her head; Kaiza reminded her much of his mother, deadpan as ever. "Well, let me put your speculations to rest, as I was there when you came from your mother's-" she was cut off by a piercing whistle following after a horrified look on Kaiza's face.

"Toshi!" Kaiza called and Katara watched as a snow leopard caribou lifted its head from the ground and looked in the direction of his owner before standing it's full height, almost six feet tall, stretching and launching itself over to him. It ducked behind Kaiza and shot the boy into the air.

Kaiza landed on his back and waved at his grandmother. "I'll catch you later, grams!" he called before Toshi took off outside the gates, leaving Katara laughing.

"Don't be late!" she called after him.

Kaiza sighed in relief as he left the Compound. He could hear the gate close as he left and rolled his eyes, he didn't understand why the kept Korra locked in there most of the time. Of course, Korra's avatar training was important but that didn't mean she couldn't have fun.

He couldn't believe his grandpa Aang would order that she stay in the Southern Water Tribe instead of traveling the world like he had. Kaiza smiled as he thought about the world outside of the Southern Water tribe, he couldn't wait until he was of age to leave.

He had no intentions of joining the South's government, he had no interest in fighting, but he wanted to travel and see what else was out there. He remembered traveling with his the stories his parents told him and his siblings.

They traveled the world and only came back after grandpa Aang died leaving grandma Katara alone. Kaiza didn't understand why his neither of his uncles could come and help, too. At first, he believed they had dire responsibilities that's why it was left to his mother but he quickly dismissed it that when he saw the resentment on his mother's face.

Shaking his head, he looked down at Toshi. Despite his size, he was still nothing but a cub and it was only because of whom his family was that the chief allowed him to keep Toshi. No one in the South would deny the Avatar's grandchildren anything, as snotty as that may sound.

Kaiza saw they were coming up to Harbor City and grinned widely as he spotted a couple tiger seal lying around the ice-covered boulders. When they came to the entrance, Kaiza waved at the attendants standing there but never slowed Toshi down.

Toshi weaved swiftly through the citizens of harbor city and didn't come to a stop until they made it back to their home. Kaiza hopped off Toshi and petted him. "Good boy." He cooed affectionately before opening the door and walking in.

Toshi walked in behind him and kicked the door shut before lying down in the common room and closed his eyes. Kaiza rolled his eyes. "For a feline, you can be really lazy." He taunted but only got a snore in response.

Kaiza sighed at the warmth radiating from the furnace and shed his coat, leaving him in his long sleeved shirt. "Kaiza, son, is that you?" he heard and looked up in time to see his father, Satoshi, walk into the room.

A brilliant smile made its way across Kaiza's face before he threw himself at his father. "Dad! I didn't know you came back today!" he exclaimed.

Satoshi chuckled deeply and placed a hand on his son's head ruffling the dark curls upon his head, making them even messier. "It was a split second decision, my fleet finished what we were to do in Omashu early and at the last moment decided to come home." He said.

His father was a commander, despite not being from the Southern Water Tribe nor being a water bender, but again, being married to the daughter of the Avatar had its perks, not to mention he was a good friend to the Chief of the tribe.

Kaiza's eyes lit up at the mention of Omashu. "Omashu? Did you see grandma?" he questioned excitedly.

"I had and she had something for me to give you and your siblings, which you won't see until they're here." He added.

Kaiza sighed but was nonetheless smiling. He looked up at his father and couldn't help but study him. He was told many times that he resembled his father and grandmother, a lot. He had his father's light olive skin, he had the almond shape eyes his father possesses but his father's eyes were green, and black hair.

He didn't see it. His father was a tall and lean man, standing with a sense of pride, he stood over Toshi about two inches, his eyes were green, a rare trait for a fire nation let alone a fire bender but while Satoshi's mother was Fire Nation, his father was of earth kingdom and an earth bender. His hair was long and black, done up in a fire nation bind while the rest flowed down his back. He wore Water Tribe armor.

Satoshi gazed down at his son and chuckled. "Well, you're mother is upstairs, she should be down in about-"

"Now." Kya cut in with a smile while walking into the common room with a seven-year-old following after her with his hands behind his back.

Kaiza stepped away from his father and smiled at his mother before scowling at the seven year old. The boy was tall for his age, a few inches shorter than Kaiza; he shared the same tan skin as his mother. His eyes were ice blue, his hair shaved on the side and the rest pulled into a wolf tail. He wore a dark blue sleeveless shirt and pants with brown boots.

What was more concerning was the smirk he had on his face. Kaiza took into consideration that the boy's hands were behind his back and there was this distinctive ticking sound…Kaiza's eyes widened and then narrowed dangerously. "Lee, don't you dare!" he snapped but it was too late.

Lee revealed what he was hiding behind his back was a hand sized ball and tossed it to the ground before him. Kaiza instinctively took a step away and acted quickly. Water from the pail in the corner of the room sprung to life and captured the device before turning to ice.

The seven year old snorted and then pouted. "You're no fun." He accused.

Kaiza leveled the boy with a dark look that had the boy fleeing behind their parents. "Kaiza!" Kya exclaimed scolding as her waterbending son began to gather water from his waterskin and covered his arm in a water partial water cloak. "No bending on your brother."

Kaiza sighed and returned the water back to his waterskin before tossing it from his hip and onto the hook next to his coat. "Fine, but the next time he tries that, I freeze his head." He threatened glaring at his younger brother, who stuck his tongue out at him.

"That can wait until your brother and grandmother gets here, then we can have dinner."

"What a fun time that sounds like." Kaiza muttered as his mother headed towards the kitchen, fortunately not having heard him, but his father had and shot him a mock stern look. Kaiza snorted and followed after his mother.

(End)

Just let me know what you all thought of this one. I never thought to write a Legend of Korra fanfiction but that was only because I didn't think I'd like Legend of Korra until I decided to give it a chance and finished the first and second season.

It wasn't what I expected and actually very good!

Now, I know that Kya didn't have any children, what I thought strange as she seems to have more parental instincts than her brothers. Satoshi on the other hand is also an OC along with all the sons, if you hadn't guessed.

Satoshi is of Earth Kingdom and Fire Nation while Kya is Water Tribe and Air nomad, so I think everyone guessed where I went in terms of their children.

No, none of them are Mary Sues or Gary Stues. I made it so that Kaiza is a talented water bender yes but nothing where he'll start doing impossible water bending techniques.

I thought it would be a good idea to have him a waterbender, Korra tends to levitate towards fire and earth in terms of bending for fighting, besides the Pro-bending tournaments.

And I know that I didn't introduce Hakoda, who was named after Katara's father, but you will meet him soon. The rest of their siblings will come after.

Next chapter will be a time skip, leave a little mystery for Kaiza's past.

As fot pairings, I'm a big fan of Korra and Asami, they give me life. But as for Kaaiza, I'm not sure, I'm not against same sex pairings so if you have suggestions, comment.

See you next chapter.
