A/N: This first chap is pretty long, but that's because it's heavy with descriptions to set up the story. I just want you guys to get to know my interpretation of Dad Aang, Mom Katara, and their kids a bit better. The next chapters will be more focused on the plot, and relatively shorter. :)

EDIT: In response to Sofia's (guest) review, yes, I'm aware that Bumi is the eldest. I started writing this before TLoK Book 2 came out, so I'm sorry for the canon inconsistencies. I included a note regarding this in chapter 10, but I decided to put one in the first chapter as well. I'm also considering editing the story to make it canon-compliant.

I do not own Avatar: The Last Airbender or Legend of Korra.

*I included LoK in the disclaimer 'cuz Kya, Bumi, Tenzin, and Air Temple Island were mentioned in only that show.

Kya, Bumi and Tenzin knew all about their parents' power. For crying out loud, their father was the Avatar, the master of all four elements, the man who stopped Phoenix King Ozai from conquering the world, the one who restored and maintained balance between the four nations, or as they were called now, the United Republic of Nations.

And their mother was Master (or Lady, as she was sometimes called, being the Avatar's wife) Katara, the best waterbender and healer in the world. One of the things that made her stand out was her prodigious skill in both combat and in healing; due to the traditions in the North Pole, most waterbenders were trained in only one of the two. It was ironic, actually, that she had the ability to both ease and inflict pain on anyone she wished.

However, the family lived in a time of peace, the peace their parents, along with their friends, had worked so hard for. The only bending they saw from their Dad was . . . rather simple, though clever and practical. Aang used his mastery of the elements not only to bring peace to the world, but to make everyday things easier. He used airbending to put out the candles, dry up the boys when Kya waterbended them, give the kids a little help when they tried to fly a kite, chase after them when it was bed time (eventually using his air scooter sometimes), and to cool them off. He earthbended benches to sit on, forts and sand/earth dummies for the kids to practice on, and to create a miniature zoo as a birthday gift for Bumi once. He used firebending to start a fire in their fireplace, to heat water, and to light the candles. He didn't waterbend much, well, in the kids' sight, at least. He only did so to help his wife, and she rarely needed that.

Their mother used waterbending to give them a bath when they were little, cool their drinks, fish, cook, and, occasionally, give the kids an ice skating rink in the middle of summer. And when one of the kids got hurt, say, scraped a knee after some roughhousing, she healed them in the flick of a lemur's tail. She did the same with her husband.

They had heard how their parents, along with Uncle Sokka, Aunt Suki, Aunt Toph, and Uncle Zuko, had saved the world. From history class, from their friends, their friends' parents, their parents' friends, and of course, from the heroes themselves. They knew that their parents could kick some serious butt, though they had never actually seen them fight. So there was no way to prepare them for what they were about to witness.

It was a regular day on Air Temple Island.

"MOOOOOMMMM!" someone yelled.

Katara, who was in the kitchen steaming fish and stewing vegetables for lunch, sighed. Her kids were at the bickering stage, and she wasn't enjoying it much.

She tried to ignore the first yell; there were times, though rare, that the children were able to sort it out by themselves. So she resumed cooking. The fish was almost done; she had to keep an eye on it. She wiped away the sheen of sweat that had gathered on her forehead using her sleeve.

Nowadays, she wore a blue Water Tribe outfit with fur lining at the hems. She didn't carry her waterskin around anymore; she lived on an island and there was no one after anymore. But even if this was the case, she and Aang still had training sessions every month or so, just so they wouldn't get rusty. This wasn't how she kept her lean and fit stature, however; she had discovered that being a mother was more physically draining than any fight.

She wore her brown-black hair down; with all the trouble the kids made, she had often found her braid coming apart before the day ended. The rest of Team Avatar teased her about it, wondering why her braid almost always stayed together in the old days, considering the fact that they were being hunted down.

She still kept her hair loopies, however. Like Sokka had said, it was a part of her identity, as with her mother's necklace and the betrothal necklace Aang had made her a couple of years after the war had ended. She smiled, remembering; though she was happy with her present life, she sometimes missed the action-filled, suspenseful, on-the-go life she had when she was fourteen. There were times when she thought that taking care of kids was more stressful than being on the run.

This was one of those times.

"MOOOOOMMMM!" the voice yelled again. Katara thanked the spirits the food was done cooking. Making good use of her waterbending, she encased the fish in hot water and transferred it to a waiting porcelain bowl. She did the same with the stew.

"MOOOOMMMM!" Katara hurriedly went outside, though she wasn't eager to find out what the problem was this time.

The kids were in front of the pond. 10-year-old Kya was pouting, her hair windblown (in a very unflattering way) and a bruise on her right arm. 6-year-old Tenzin had a black eye and a red mark on his cheek, and 8-year-old Bumi was dripping wet.

Katara groaned. Not again, she thought. It didn't exactly help that two of her kids were benders, and one was a warrior-in-training. Add that to the fact that the three had completely different personalities.

Her eldest and only daughter, Kya, was a headstrong and tough girl, sometimes reminding her of her good friend Toph Beifong. Like her namesake, she was fiercely protective of her family (though she also tended to pick fights) and extremely brave. She was a talented waterbender who had shown a significantly larger amount of interest in combat rather than healing. Kya believed that if she was good in combat, she couldn't get hurt; thus, there was little need for healing.

As for her second child, Bumi, Katara had always thought that he couldn't have been more appropriately named. He was just like Aang's friend; he was easygoing, loved to laugh and was always raring to go on an adventure. He loved cracking jokes (even those that no one found funny) and was incredibly inquisitive. Though he was a non-bender, he had made up for it with his knack for weapons and planning. Of course, his uncle was proud of him, and had even started teaching him how to be a warrior, "Sokka-style".

Tenzin, on the other hand, was the complete opposite of his two siblings. He was always calm and collected; rather serious, in fact. He was an airbender, but he was far from the goofy child his father had been. When it came to something or someone he felt strongly or cared deeply about, however, he had a relatively quick temper.

One of these someones was Lin Beifong, Toph's daughter. The adults had all noticed their close friendship, and Sokka and Zuko had already bet money on the two ending up together one day. Unfortunately, Team Avatar wasn't the only who had noticed, as Katara soon found out.

"Mom! Tenzin airbended at me!" Kya whined. Being the eldest, and a girl, she was naturally a tattletale.

"Kya water whipped me!" Tenzin countered.

"Only because you messed up my whole room looking for some stupid rock! If only you cleaned your room, none of this would have happened."

"I'm not cleaning anything until I get my special rock back," the airbender huffed stubbornly.

"And you're not getting it until you tell me whether or not you like Lin," Bumi told him, sticking his tongue out.

"Mom, Bumi's being mean!"

"Mom, Bumi stepped on my doll while running from Ten," she complained.

The little warrior turned to her, defensive. "Well, I wouldn't have stepped on it if you didn't leave it lying on the floor."

"I DID NOT LEAVE IT LYING ON THE FLOOR! I put it on top of my dresser and Ten knocked it down looking for that rock." She shot a glare at her youngest brother.

"MOM-"

"ENOUGH!" Katara silenced them. The children backed up, scared to see their mother this way. And the fact that the water in the pond behind them was sloshing around violently. This, they had learned, meant that she was really mad.

"Let me get this straight, and correct me if I'm wrong. Tenzin couldn't find the rock Lin gave him because his a room was a mess, so he tried searching Kya's room instead. It turned out Bumi had the rock and wouldn't give it to Ten until he answered a question." At this, Tenzin turned even redder. "Tenzin chased Bumi around, and in the process, Bumi stepped on Kya's doll. You took the fight here to the pond, resulting in . . . this." She gestured at the three children. None of them contradicted her.

The master waterbender shook her head and sighed. "When your father hears about this—" she started, but a voice cut her off.

"When I hear about what?" Aang asked, appearing out of nowhere.

Over the years, Aang had grown up to be quite a looker; of course, he had always been cute (adorable, even, to Katara) as a boy. He was now much taller than his wife, and his face lost its boyish roundness, becoming more chiseled as he aged. He maintained his naturally lean build, though he became slightly more muscular. He usually wore airbender robes, though they weren't the same as the ones he wore as a teenager. They had been patterned after ancient paintings of airbenders that had been found in the ruins of the Air Temples. Clothes tailors from the four nations had worked to make it and presented it as a gift to the Avatar. Needless to say, he was overjoyed at the thoughtful present.

He had also started to grow a beard, much to the amusement of his friends ("Looks like Twinkletoes is finally becoming a man," Toph had said, smirking.). When he asked Katara about whether or not he should shave it, she had just laughed. Afraid to ask anyone else, especially his brother-in-law, he decided to keep it, though making sure it never grew more than a slight stubble.

The Avatar had his eyebrows raised in curiosity as he took in the scene: his wife frazzled, and the kids with various injuries.

"The kids got into a fight," she said, obviously tired. She then proceeded to explain exactly what had happened.

"Mm-hmm," he said, rubbing his slight beard, just as he did during council meetings. Katara trusted Aang's judgment; he was the Avatar, after all. He brought peace to the world. How much more to his three squabbling children?

"Kya and Tenzin, we've already told you, no bending at each other. And Bumi, no using the stuff Uncle Sokka teaches you against your brother and sister either." This caused each kid to pout. "Kya, you know better than to lose your temper over something like this."

Kya sighed. "I know, Dad. Sorry."

"Bumi, give Ten back his rock."

"Here you go, Ten." Bumi handed the rock to his brother.

"And Tenzin," The youngest looked up at him. "I know that being unorganized is an airbender's nature, but please do clean your room."

"I don't wanna clean my room," he whined.

"It's your room, and your responsibility, Ten. Unless, of course, you want to share a room with Bumi," Aang said slyly.

Tenzin gave his brother a quick glance, and his eyes widened in horror. "No thanks," he said quickly. "I'll go clean it."

"Let me heal your eye and cheek first, Tenzin. You too, Kya," their mother sighed.

The healer summoned a wisp of water from the pond and positioned it over Tenzin's eye. The water glowed and a few seconds later, Tenzin's eye had become noticeably less swollen and its color had returned close to normal. She did the same with Kya's bruise.

Meanwhile, Aang dried up Bumi with a blast of air. The three children muttered thanks and retreated back into the house.

Katara sighed as she watched the children walk away. "What are we going to do with these kids, Aang?"

"C'mon Katara, it's just a stage. I'm sure I wasn't the easiest airbender to raise." Katara smiled at that; she knew her husband had always been an incurable prankster. "And I bet the kids are just as hotheaded as you were at that age, too."

Half-teasing and half-annoyed, Katara waterwhipped him lightly on the arm. "Ow! Correction: as hotheaded as you are right now." This brought on a glare from his wife, so he tried to lighten the mood.

"You're just proving me right," he teased. "Loosen up, Katara."

Katara opened her mouth to say something, but her husband's signature goofy grin softened her, as always. "I guess you're right. It's just—who knew kids could be so stressing? Just imagine if Bumi was a bender as well," she shuddered.

"The more, the merrier," Aang shrugged. Katara responded with an eye roll.

"I think I should get back to preparing lunch. Sorry for having to disturb your Avatar work, sweetie," she said, kissing him on the cheek. "I know how stressful it must be to build a city. Dad sure had his hands full rebuilding the Southern Water Tribe."

"Hey, I have as much duty to my family as to the world, don't I?" He winked.

"The world's more important, Avatar," Katara smirked.

"But you are my world," he responded, landing a light kiss on her lips.

Katara pushed him away with a playful shove. "You're such a sap," she laughed.

"And that's why you love me." He had on that adorable grin she loved so much.

She couldn't help but smile back. "True," she conceded. "All right, enough distractions. Back to your Avatar work and back to my cooking."

"But this is more fun," he whined. It was useless; the waterbender didn't waver one bit.

"Fine, fine," he said, wrapping his arm around her waist instead. They walked back to the house together.

"What's for lunch, by the way?" he asked.

"Oh, I'm making your favorite. Stewed sea prunes!"

"Katara!" he complained. "It's not funny."

"Oh, trust me, it is," Katara said, laughing. "But seriously, Aang, I still don't get why you hate that dish so much."

"I don't know, it's just so . . . ugh," he shuddered. "What I still don't get is how you can eat it without gagging."

"Who'd have guessed that the Avatar would be afraid of a Water Tribe specialty?" she smirked. "If it came down to battling a whole army of rebels and eating ten bowls of sea prunes, which would you pick?"

"I gotta admit, I'm having trouble deciding."

"Seriously, Aang?"

"To be honest, yes. And, um, while were on the topic, were you serious about stewed sea prunes for lunch?"

"When have I ever not been serious?" She smiled sweetly at him.

"Katara, quit messing with me!" He started pouting like a three-year-old, much to his wife's amusement.

"And you said jokes didn't run in the family," she said, laughing again.

What do you think of the kids' personalities? And my take on the Avatar family in general? :)
