Katara: Water, Earth, Fire, Air

(One by one, six figures do something to show off their skills: the waterbender weaves a stream of water from the ground, around him and then thrusts it towards the side, the earthbender kicks the ground bringing up a large rock before he kicks it away, the firebender twists around as she summons fire from her foot before doing a high kick to the ground and makes the flames spread,, the airbender drops down and then with a circle of his arms he creates a blast of wind.)

Katara: My grandmother used to tell me stories about the old days; a time peace, when the Avatar kept balance between the Water Tribes, Earth Kingdom, Fire Nation and Air Nomads. But that all changed when the Fire Nation attacked.

(A map of the Four Nations is shone before flying through the mountains of the Earth Kingdom, before coming to where docked on a shore, five Fire Nation ships with the Hydra insignia released their soldiers. With a jump forward and a palm thrust, the firebenders released a wave of fire.)

Katara: Only the Avatar, mastered of all four elements. Only he could stop the ruthless Firebenders. But when the world needed him most, he vanished.

(The Avatar, a man with a crown on his head and dressed in robes stands on a pillar of stone as he bent the four elements of water, earth, fire and air to show his skill in the arts of bending. After releasing a powerful disk of wind, he disappears from existence.)

Katara: A hundred years have passed, and the Fire Nation is nearing victory in the war. Two years ago, my father, and the men of my tribe journeyed to the Earth Kingdom to help fight against the Fire Nation, leaving me and my brother to look after our tribe.

(Across the lands of the other three nations, the Fire Nation has laid destruction across everything in the war in flames. Four Water Tribe boats made their way from the village to go help in the fighting, leaving a young man and his sister to look after the tribe.)

Katara: Some people believe that the Avatar was never reborn into the Air Nomads and that the cycle is broken, but I haven't lost hope.

(Up close, the siblings looked worried as they watch their fellow tribesman. But behind her saddened eyes, the younger Water Tribe girl still had hope that things would get better.)

Katara: I still believe that somehow the Avatar, or maybe he and a new hope will come to save the world.

Book One: Water

Chapter One: The Boy In the Iceberg and the Man from the Sky

(Near the end of the fight between the Avengers and the Hydra recruits)

Somewhere in one of the cold Poles, the air and water seemed pretty calm. On a glacial shore, two sets of footprints went over hills of snow to some destination. Amongst the icebergs and massive glaciers, in the cold waters a small canoe sat floating in the water.

In the boat, two people; a brother and sister, looked over the side of the small boat as they fished. The wind softly whistled as the sibling's canoe drifted on the cold water. The brother had a look of determination on his face as he raised his spear at the water.

"It's not getting away from me this time." He said with confidence. Turning to his sister he smirked and said, "Watch and learn, Katara." He looked back to the water and raised his spear higher and said with the smirk still on his face, "This is how you catch a fish."

Katara, the younger sister, had an eyebrow raised to her brother's cockiness. With a slight turn of her head, she saw a fish right in front of her in the water. As the fish swam Katara took off her left glove to try something. She looked nervous for a moment, but then taking a deep breath, she held out her hand towards the fish, towards the water. Moving her hand in a waving like motion, she causes the water to bend around the fish as she pulls it out from the ocean in a bubble. Her face lights up as she said, "Sokka, look!"

"Shh, Katara. You're gonna scare it away." Sokka said as he wasn't paying attention to her as she bent the captured fish towards the boat. He continued to look down in the water from his side of the boat as a smile at the thought of eating the fish. He licks his lips before saying, "Mm… I can already smell it cooking."

Katara tried to show him as the floating fish was know right above her head, "But, Sokka, I caught one."

As she bent the water with the fish towards the middle of the boat to put the fish in it, it was over his head as Sokka raised his spear, and the end of it punctured the bubble. The bubble bursts with the fish jumping back into the water and Katara yelling, "Hey!"

Sokka gasped as the cold water fell on his head. Turning half of him around, he angrily questions, "Why is it that every time you play with magic water, I get soaked?"

With a sigh, Katara then explains to him, "It's not magic. It's waterbending, and it's-"

"Yeah, yeah. An ancient art, unique to our culture, blah, blah, blah." Sokka interrupted as he wasn't entirely interested. Katara had her arms crossed as he turned around to face the front he then somewhat mocked her as he said while getting the water off, "Look, I'm just saying that if I had your powers, I'd keep my weirdness to myself."

"You're calling me weird?" Katara questioned. She then points out with a half-smile, "I'm not the one who makes muscles at myself every time I see my reflection in the water."

Her case was proven in point as Sokka was doing just that. He turned himself back around to look at her with an annoyed expression. But with a thud and a jerk, the two siblings gasp when Sokka looks ahead of them. He sees that they're in some trouble as the current picked up and the ice flows started to drift together. Sokka used the paddle to steer the canoe away, but it got harder as the converging ice made the path narrower by the second.

They made it to a clear path of water. Sokka grunted as he paddled for their lives, but the ice flows started to converge again. The canoe hit another ice flow. Katara shouted, "Watch out!"

As they try to make it out, Katara yells, "Go left! Go left!"

The canoe came to a spot where it was boxed in by the ice flows. As the ice started to crush the canoe, the two Water Tribe siblings jumped out with a gasp. They slide on the ice flows as the canoe was completely crushed. Katara grunts as she slid to a stop at the edge of the iceberg. Both siblings were now stranded on sea of small icebergs and the literal ocean.

Sitting up, Katara commented, "You call that left?"

"You don't like my steering?" Sokka shot back. Then mimicking the movements of the art he said, "Well, maybe you should have waterbended us out of the ice."

This makes Katara angry as she questioned and stood up, "So it's my fault?"

"I knew I should have left you home." Sokka rudely said with irritation voice. He looks down and makes a very negative comment, "Leave it to a girl to screw things up."

This one comment causes Katara to become angrier as her face twitched from the comment. Letting her emotions come to the surface, she pointed an accusing finger as she shouted, "You, are the most sexist, immature, nut-brained…"

She puts her hands up to her head from the aggravation and when she threw them backwards she unknowingly caused waves as she shouted, "I'm embarrassed to be related to you!" She gave a big swing of her arms, and her waterbending caused an iceberg to crack. The ice groaned from the sudden force.

Sokka happened to look up at that moment and noticed how Katara's bending reacted with her anger. It made him nervous as she kept yelling, "Ever since Mom died, I've been doing all the work around camp, while you've been off playing soldier!" She sent another wave back, causing the iceberg to crack even more.

"Uh… Katara." Sokka tried to warn as he pulled on his mouth with his left hand and tried to point with his right. But she wasn't in the mood as she points out, "I even wash all the clothes! Have you ever smelled your dirty socks?! Let me tell you, not pleasant!" This time she held both of her arms up before throwing them down in anger. It causes the ice to crack even more.

The actions of her fury cause Sokka to become even more scared as he tried to make her stop, "Katara, settle down!"

Thinking that it was another attempt for him to control her like most of the time, her anger flared up again as she yelled, "No! That's it! I'm done helping you! From now on, you're on your own!"

She threw back another wave at the glacier, this time creating even bigger cracks in the ice. Sokka whimpers to what's behind Katara as she looks back with a gasp. The giant pillar of ice breaks apart and crashes into the see, rocking the sibling's iceberg. Both of the scream as their small piece of ice is sent pushed back. Both of them laid on their stomachs and had their closed their eyes to the stinging wind as Sokka held on to his sister. Their berg went back a few feet until it came to a stop.

Sokka's expression turned from frightened to weirdly annoyed as he said, "Okay, you've gone from weird to freakish Katara."

"You mean I did that?" She asked. Putting fake pride into his voice he said, "Yep. Congratulations."

A split second later, the water in front of them started to glow a bright bluish color that stuck out from the darker blue of the ocean. This made the siblings wonder what it was as the glowing light started to get bigger. Sokka and Katara get up to their feet and stepped back right as something started to emerging from the water. A moment later, a new iceberg erupted out of the water. As the domed iceberg bobbed on the surface, both Water Tribe siblings could see something inside of the glowing ice. Katara took a step forward to see what was inside, making Sokka nearly stop her, but she didn't get too close. She viewed at whatever was inside, and saw a large creature and what appeared to be a human inside of the berg. Katara gave an odd glance as she looked at it. Then suddenly, the being opened his eyes.

Both Water Tribesman gasp at this, and seeing that he was alive, while Sokka got into a fighters stance, Katara exclaimed, "He's alive!" Then reached behind her brother's back and grabbed his club. Pulling her hood up as he felt for what was missing, she said, "We have to help." before running forward.

"Katara, get back here!" Sokka said, fearing that whatever it was could be dangerous. He ran after her pointing out, "We don't know what that thing is!"

He grabbed his spear as she jumped from one patch of ice to the next. When she reached it, she got closer to the side and raised the club. With a forced grunt, she started to the packed ice. Smacking the ice four times, she put most of her strength into the fifth swing. It did the trick as steam shot out of it with a hiss. The blast of steam caused both of them to gasp. Sokka held Katara close as the steam settled and watched as the domed ice start to crack. The crack ran up the side, groaning as the cracks grew by the second. When the crack reached the top of the berg, the ice shattered as a great pillar of light shot up high into the sky.

The power of the light affected everything, from making giant ripples in the water to waking a pack of arctic seal leopards, making them rise with a groaning roar.

However, Sokka and Katara were not the only ones to witness the pillar of light. On a metal ship, sailing through the cold waters not too far from the pillar, a young man with a scar from a burn over his left eye and ear, saw the pillar of light.

"Finally." The teenager said with a look of renewed determination. Turning on his heel, he faced an older man and said, "Uncle, do you realize what this means?"

"I won't get to finish my game?" The man said as he played some kind of tile game while drinking a cup of hot tea. Turning back to the front of the ship, the teenager said, "It means my search it's about to come to an end."

His uncle sighed before putting a tile down on another one. His nephew said while pointing to the pillar of light as it faded, "That light came from an incredibly powerful source. It has to be him."

"Oh, it's just the celestial lights." His uncle put it off as he raised a tile into the air. Then he said as if it were just nothing, "We've been down this road before, Prince Zuko." He kept talking as he started to place a tile with three swirling circles on a tile that looked like the image of fire, "I don't want you to get too excited over nothing." Trying to calm his nephew he gestured for him to join, "Please, sit. Why don't you enjoy a cup of calming jasmine tea?"

Prince Zuko tensed up before sharply turning and snapping, "I don't need any calming tea! I need to capture the Avatar." Looking up to the helmsman, Zuko ordered and pointed, "Helmsman, head a course for the light!"

His uncle only looked to another of tile with the swirling circles and placed it on the previous tile with the swirling circles. The wind started to whoosh over the table, making the tiles move a little.

Back at the pillar of light's former sight, both Sokka and Katara still shielded themselves from the blast of air and light. When they opened their eyes, they first looked to each other before looking to the source of the light. Sokka held up his spear as they waited to see if something would emerge.

From a top the ridge of the ice, the human being climbed and stood on the top. Because of the light, the being appeared as if to be mostly blue. Feeling unsafe about the being, Sokka took a more threatening pose with the spear and said, "Stop!"

The blue light faded, revealing that the being was only a boy wearing a yellow top shirt and pants, a red colored belt, brown boots and a red half-over cloak, not to mention glowing blue tattoos on his forehead and hands. As his tattoos stopped glowing, the boy faints. This causes Katara to gasp as she catches him as he fell. They both groan as they hit the ground.

Sokka, being the cautious yet inconsiderate one, started to use the bony end of his spear and nudged the boy's head. Each time he nudged, the nudges made boinging sound. After a few more nudges, Katara became annoyed by it and said while slapping it away, "Stop it!"

Knowing that he would back off, she set the boy down against the ice. The boy moaned as he started to wake up. When he did open his eyes, he saw that he was staring into the face of a beautiful girl and gave a small gasp. Katara offered him a smile as the wind blew against her hair loopies.

"I need to ask you something." The boy said weakly. Katara grew curious and asked, "What?"

"Please, come closer." The boy said. She did as he asked, and asked what he wanted, "What is it?"

The boy drowsily blinks his grey eyes. Then, he put on a big grin and looked more energetic as he comically asks, "Will you go penguin sledding with me?"

"Uh, sure, I-I guess." Katara said as she sat up, now feeling a little weirded out and confused. The boy then did something as he made himself quickly stand up right. The action causes Sokka to gasp as he jumped back in fright, making Katara look at him with a raised eyebrow. The boy looks around and then asks, "What's going on here?"

"You tell us." Sokka demanded. He didn't understand any of what just happened as he bombarded the boy, now rubbing his head, with questions, "How did you get in the ice? And why aren't you frozen?" On the last question, the Water Tribesman used the sharp end and lightly poked the boy in the stomach with it.

"I'm not sure." The kid said as he pushed the spear away. A loud snoring sound comes from the other side of the wall of ice, making the tattooed boy gasp. The kid started quickly climb up the ice, grunting with every step. When he reached the top, a big grin on his face again as he started to slide down the ice. When he reached the bottom, he jumped up into the air and said, "Appa! Are you all right?"

He landed on the head of the sleeping something. His giant furry friend still slept as the boy tried to rouse him, "Wake up, buddy." He used his hand to open the creature's eye lid. But it didn't work as the eye lid went back down. Jumping down to the face of the creature, he put his hands on the creature's lips and tried to raise the head. But all it really did was pull on the lip with a few grunts.

Sokka and Katara came around to an opening to see what was going on. Their eyes grow wide as Sokka lets out a gasp and his ears grow comically bigger as the boy keeps trying. His giant furry friend finally wakes up, and licks the boy's back. This causes the boy to laugh and said, "You're okay!"

The boy lands on his feet and turns to hug the creature's snout. The furry creature grunts and growls as it rose to its feet. The creature was massive, it had two horns on its head, three legs on each side which meant six in total, a long flat tail, and it was mostly covered with white fur and had a long patch of grey fur that looked like a giant arrow that ran from his tail to his head.

"What is that thing?" Sokka questioned as he and his sister came closer. The boy looked back and said, "This is Appa, my flying bison."

"Right." Sokka sarcastically said. He then points to his sister and said, "And this is Katara, my flying sister."

Both she and the boy gave him a raised eyebrow. With the sound of a low growl coming from Appa, the boy turns to see the bison's nose starting to twitch. Appa took a deep breath and let out a huge sneeze. The boy yells and ducks as Appa lets loose a huge stream of snot. Unfortunately, all the snot landed on a now disgusted Sokka. He screamed as he used the snow to get the snot off of him. He gasped as a smiling Katara watches him trying to get it off. Sokka then wiped his face in the snow to rub it off. The boy gave a smile as he reassured him, "Don't worry, it'll wash out."

Sokka didn't feel any better as he wiped the rest of it off of his face with a groan. Katara looked like she was really grossed out. The boy decided to ask, "So, do you guys live around here?"

Sokka's attitude changed from grossed out to cautious again as he pointed the spear at the boy and said, "Don't answer that." He pointed to the sky as he said, "Did you see that crazy bolt of light?" He stood up on his feet, with spear still pointing at the kid, and accused, "He was probably trying to signal the Fire Navy."

"Oh, yeah," Katara skeptically said. She pushed her brother out of the way, "I'm sure he's a spy for the Fire Navy." She looks to the boy and sarcastically said while Sokka looked a little skeptical at her, "You can tell by that evil look in his eye."

The boy didn't show any emotion on his feet for a moment, but then he put on a crazy smile on his face. Katara then explained to the boy, "The paranoid one is my brother, Sokka." Sokka then held up a hand as if to say hi, and then she said, "You never told us your name."

"I'm… ah…" The boy tried to say, but something stopped him. He couldn't say anything but, "Ah, ah, ah, ah, ah…"

Then like Appa, the boy let out a huge booming sneeze and then shot up high into the air. Katara and Sokka took a step back from the blast. Both Water Tribe siblings look up to the sky in wonder and amazement. The boy quickly came back down and slid down the ice, and stopped by pushing his heels into the ice. When he stopped before them he introduced himself, "I'm Aang." Then using his finger he wiped his nose with a sniffle.

"You just sneezed," Sokka said and then pointed up into the air as he said, "and flew ten feet in the air."

"Really?" Aang said as he looked up to the sky, "It felt higher than that."

Katara gasped in realization and said, "You're an Airbender."

"Sure am." Aang confirmed. But before anything else could be said, Sokka thought he started hearing something. Looking around he said, "Do you guys hear something?"

Both Aang and Katara looked around as well. It wasn't long before they all looked up to the sky and saw something falling. Sokka looked over to the Airbender and asked, "You didn't happen to throw something when you went up, did you?'

Aang only shook his head as the thing in the sky drew closer. Taking a closer look he said, "It kind of looks like a person with a shield of some kind."

As the man drew closer, Katara noticed that the person was falling right towards them. Grabbing both boys' arms, she pulled and said, "Watch out! Move!"

All three kids and Appa then jumped backwards as the man impacted the ice where they once stood. The impact created a giant mushroom cloud and sent a lot of ice flying, thus making Aang, Katara and Sokka cover their faces. Luckily, the ice shards didn't hit the kids nor Appa. Lowering their arms, the three looked towards the crater as the air cleared of the dust.

Aang, being the brave one at the moment, tiptoed towards the crater. As he got closer to the crater, he could see the thing more clearly. The person in the crater was a man dressed in a blue covered uniform, had a blue helmet and the round grey shield was on his left arm. The uniform itself was decorated with red and white at the man's midsection, a white star on his chest, not to mention the attachments to his belt. Aang crept down into the crater and got closer to the man. Just as he was about to see if the man in blue was still alive, a familiar spear with its butt bone appeared and started to nudge the man in the head. Both Aang and Katara looked to Sokka with a raised as he kept going. Aang quickly slapped the spear away and said, "Stop it!"

Aang gave the Water Tribe teen an annoyed glance just as the man started to stir with a groan. Looking down, all three kids watched as the man's eyes twitched open. When he did open them, the first thing he saw was three pairs of eyes staring down at him. It made him jump a little, and him jumping made them jump a little. Looking around, the man first noticed that he was surrounded by ice which it started to groan as more cracks started to appear.

"Move it!" The man said. All four of them ran and climbed out of the crater as the bottom of it gave way. Water could be seen as the cracks let it in. When all four were in the clear, the man looked to the children with a raised eyebrow as they took a deep breath. No one said anything for a moment. Sokka then broke the silence and asked, "Now who are you?"

The man shook his head, trying to process everything that just happened asked, "Wait, wha-?"

"Now. Who. Are. You?" Sokka asked again more slowly. The man then hesitantly held out the shield-less hand and said, "Name's Steve, Captain Steve Rogers."

"Nice to meet you Steve." Aang said as he took the older man's hand and shook. Then with his free hand, he introduced the Water Tribe siblings, "And these two are Sokka and his sister Katara."

Steve nodded to the two before starting to look around again. He saw the ocean and all the ice bergs. Looking back to the kids he then noticed that Sokka was walking around him. Taking a chance the young Water Tribesman asked, "So if I can ask, Steve, where did you come from, and what exactly is with your 'uniform'? And you're a captain for who now, exactly? And you wouldn't happen to be another Airbender?"

"Well, this uniform is what I wear when I go to help people." Steve explained. This peaks Katara's curiosity as she asks, "What kind of help do you do?"

"The saving kind." Steve looks to her and tells her. This makes the three kids gasp in amazement. Steve then said, "As for where I'm from, it's a little hard to explain." Then he said, "And I was made a captain because it was part of a gimmick until I became an actual a soldier back during the second World War."

"Second World War?" Sokka questioned. Steve then decided to explain, "As I said earlier, where I'm from is a little hard to explain." He was about to keep going when he heard a growl from behind, and looking back he saw Appa standing right behind him with the bison standing incredibly close. Steve looked back to the kids, as Aang quickly remembered and said, "Oh, I forgot, that's Appa, my flying bison."

Looking back to the bison, Steve said, "Uh, hi."

Appa's response was a big lick against Steve. Steve moved away and wiped himself off, then he looked to the kids again. He then further explained himself, "Let me just say, where I came from is a place called Earth. And when I said the second World War, that's the time when I got my powers."

"Powers?" Katara asked with a skeptic eyebrow. Steve laughed, knowing that it did sound a little farfetched, as he said, "Let's just say that I'm not an ordinary soldier. Back during the war, my government wanted a way to help win the war, so they decided to create a super soldier program."

He was about to keep going when Sokka decided to cut him off and said, "Giant light beams, flying bison, Airbenders, super soldiers…

"I think I've got midnight sun madness." The teen said as he started to walk off. Steve looked to the other two kids and asked, "What's an airbender?"

They didn't get a chance to explain as Sokka said, "I'm going home to where stuff makes sense."

The Water Tribe teen then saw that getting back home would be a little difficult, seeing as they were all stuck on the iceberg.

"Well, if you guys are stuck, Appa and I can give a lift." Aang offered. He looked to Steve and said, "You can come along if you want."

"Thank you." Steve humbly said. He decided to go with them since he didn't know how this world worked. Aang then took a stance and then with his arms bent in different directions, he air bent himself in a jump to the top of Appa's head with his test. Then he did two hops to where the reigns were. Katara happily said, "We'd love a ride, thanks."

As Steve and her move to board Appa, Sokka was the killjoy again as he turned and said, "Oh, no. I am not getting on that fluffy snot monster."

"Are you hoping some other kind of monster will come along and give you a ride home?" Katara asked as Aang helped her into the saddle. Then she points out, "You know, before you freeze to death?"

Steve looked over to the boy as he tried to retort back, "Uh…" but as Sokka raised his finger, he just stopped trying to fight it and sighed.

Sokka, Katara and Steve were now on board the flying bison at the back of the saddle. One was very excited, one wanted to see what would happen, and the last had a deadpanned expression as he waited. Looking back, Aang said, "Okay, first-time flyers, hold on tight." Facing forward, the Airbender looked down the bison and excitedly shouted, "Appa, yip-yip!"

He snapped the reigns and Appa gave a low growl. The bison walked over the crater and to the waters edge. Near the edge of the ice, Appa raises his tail and then with a mighty jump, he splayed out all six legs, he stuck in the air for a moment and then crashed into the water. The impact shot up huge waves. As he floated in the water, Appa started to swim. Not wanting to disappoint his new friends, Aang tries to make Appa fly, "Come on, Appa. Yip-yip."

As Katara crawled on the saddle, Sokka sarcastically complemented, "Wow, that was truly amazing."

Even though Katara and Steve shot him a glare, Aang defended the bison by saying, "Appa's just tired. A little rest and he'll be soaring through the sky. You'll see."

As she moved to pet Appa, she noticed that Aang looked at her with a big smile on his face. She then questions, "Why are you smiling at me like that?"

"Oh," Aang tried to make it sound accidental by saying, "I was smiling?"

Both Steve and Katara heard Sokka groaning from behind, "Ugh."

Katara shot her brother another look as Appa kept swimming through the cold waters.

Prince Zuko's ship kept on sailing through the freezing waters as the sun started to set. At the top of the ship, Prince Zuko stood at the railing, thinking about capturing the Avatar. His uncle soon joined him and informed his nephew, "I'm going to bed now."

He goes through the motions of the yawn with his left arm stretched out. He feels content as he said, "Yep, man needs his rest." Noticing that his nephew hadn't moved or reacted to his words made the man say, "Prince Zuko, you need some sleep."

Seeing that the prince still hadn't moved, his uncle pointed out, "Even if you're right, and the Avatar is alive, you won't find him. Your father, grandfather and great-grandfather all tried and failed."

"Because their honor didn't hinge on the Avatar's capture." Prince Zuko said. He slightly looks back as he said, "Mine does." Looking back over the water he claimed, "This coward's hundred years in hiding are over."

The group of five still lazily floated through the water towards Sokka and Katara's home. As Aang laid with his head against Appa's and his staff, Sokka laid on his side at the back of the saddle sleeping, Cap and Katara sat more in the middle of the saddle. As Steve sat looking at his shield, Katara moved towards the head of the bison. Looking down at Aang she said, "Hey."

"Hey." The Airbender said nonchalantly. He then asked, "Whatcha thinking about?"

"I guess I was wondering," She said with questions in her mind, "your being an Airbender and all, if you had any idea what happened to the Avatar."

This surprised him as he was quick to say, "Uh, no." He sat up and said, "I didn't know him. I mean, I knew people that knew him. But I didn't. Sorry." He offered a smile."

"Okay, just curious." Katara said, deciding that that was enough for now. She then said, "Good night."

"Sleep tight." Aang said back to her. When she wasn't looking, he turned around and had a nervous look on his face. Unbeknownst to him, Steve happened to be looking while leaning against the saddle but didn't say anything as they continued to float.

It was later that evening as everything had turned a grayish color and thunder boomed overhead Aang. The noise and the flash of light caused Aang to wake up. Somehow, he had been moved up to the saddle as he sat up. Looking around he sees that he and Appa were surrounded by thunder clouds. Moving to Appa's head, he took the reigns and tried to get out of the storm. He screamed as he and his beloved bison were sent crashing into the sea. After disappearing under the waves, Aang and Appa reemerged from the water with Appa roaring in fright. A huge wave sent the two back down underwater. Both boy and bison kept sinking deeper and deeper in the water.

His grip slipping off of the reign he floated ahead of Appa. As his air started to run out as they sank deeper, his face turned from looking unconscious to a serious one as his eyes and tattoos started to glow. Then smacking his fists together, he created a giant sphere of air that surrounded him and Appa. The light from him doing that could be seen from the surface of the ocean. The water surrounding the air sphere started to turn to ice, encasing Aang and Appa inside.

Katara and Steve's voices were then heard, "Aang! Aang, wake up! Come on kid!"

Aang gasps as he sat up, abruptly waking from his dream. Katara looked a little worried for him as she said, "It's okay."

He looks to her as she happily said, "We're in the village now." Standing up with Steve, with his helmet removed, standing right behind her she pointed with her thumb and said, "Come on, get ready. Everyone's waiting to meet you." Before she followed Cap out of the tent, they took a good look at the tattoos on Aang's arms, hands, legs and feet. She let's out a gasp about something as Aang puts on his shirt. Reaching towards him, she grabbed his wrist making him yell.

In a little Water Tribe village, most of the villagers were waiting as Sokka sat in the lotus position outside of Aang's tent. As Sokka sharpened his boomerang, he looked up as Katara dragged Aang with Captain Rogers following close behind. Katara pulled Aang before the gathered crowd of the villagers and introduced both him and Steve, "Aang, Steve, this is the entire village." As the villagers looked back at them, she said, "Entire village, Aang and Captain Rogers."

Putting both hands on his staff, he then does the polite thing and bows to them. Cap did the same with his hands against his sides. The villagers were a little cautious of the two as some of the women pulled their children back. This makes both boys a little self-conscious as Aang asked, "Uh, wh-why are they all looking at us like that?" He looked over him and Steve and then asked, "Did Appa sneeze on us?"

An elderly woman stepped forward and explained, "Well, I can't say much for this one…" She pointed to Steve before turning back to Aang, "But for you, no one has seen an Airbender in a hundred years." She was very blunt when she said, "We thought they were extinct, until my granddaughter and grandson found you."

"Extinct?" Aang asked in disbelief. Katara made a personal introduction, "Aang, Steve, this is my grandmother."

"Call me Gran-Gran." She said with deadpanned expression.

Sokka walked up and took Aang's staff and said, "What is this, a weapon?" Looking over to Steve's shield he said, "I already can tell what yours is, but his…" Holding it horizontally to expect it he said, "You can't stab anything with this."

Chuckling, Aang used airbending to take it back. As it came back to his hand, Steve thought, that's almost like Thor with Mjolnir.

Aang still chuckled as he then said, "It's not for stabbing. It's for airbending." Then touching it in a certain way, he caused the staff to turn into a glider. One of the wings hit Sokka in the chin, making him gasp. One of the children chuckles as another said, "Magic trick! Do it again!"

"Not magic, airbending." Aang explained. He then demonstrated a little as he moved the glider around, "It lets me control the air currents around my glider and fly."

"You know, last time I checked…" Sokka said trying to be the know-it-all. He then made a comical face as he tried to make his point, "humans can't fly!"

Steve had a smirk on his face as he said, "I once thought that nothing would surprise me anymore." He moved towards Sokka and put a hand on the teen's shoulder and said, "But I believe that there are many more surprises to come."

"He's actually right." Aang said as he put his hands where they needed to be and squatted. With smirk the Airbender said, "So you might want to check again."

Then after tensing up, he jumped up high into the air. Steve, Katara and Sokka were pushed back a little as they looked up to watch Aang. Everyone else of the village gasped as they watched Aang in amazement. One of the little girls said, "Wow! Oh, he's flying!"

Aang made the glider move from side to side and turned when he wanted to. Another girl shouted with glee, "He's amazing!"

The young Airbender did a small dive before pulling up. He looked down with a small smile as he passed over everyone. Even Steve couldn't help but be impressed as he watched the kid fly around. He then thought to himself, I wonder if he could give Thor a run for his money.

His smile grew bigger as he continued to bring fun to the village kids. His smile grew so big that he closed his eyes. Unfortunately, it caused him to crash into a snow built tower with a grunt. Steve winced from this as Katara held her hands up to her mouth while her grandmother had disapproving stare.

Aang grunted as he tried to pull himself out of the tower made of snow. It took a few tries when he finally did, he fell and rolled in the snow. Katara and Steve winced as Sokka screams, "Oh, my watchtower!"

All three of them ran to see if Aang, or the watchtower, was okay. A small ounce of a snow smacks against the now semi-buried Aang as Katara and Steve come to help him. A few children run up to them as Katara exclaims with a smile, "That was amazing!"

Both her and Steve take one of Aang's hands and pulled him out of the snow. Sokka ran past them and checked on the tower. As Aang spun the glider back into the staff, snow from the tower falls onto Sokka. He grunts as he lands on his back.

Popping his head out of the snow and said with annoyance, "You're an Airbender; Katara's a Waterbender; Steve's a super soldier." Picking himself out of the snow and sarcastically said, "Together, you can just waste time all day long."

As the teen Water Tribesman walked away, Aang and Steve look at Katara as the former excitedly exclaimed, "You're a Waterbender!"

"Well, sort of. Not yet." She humbly pointed out. The mention of 'waterbending' and 'airbending' made Steve curious again as he asked, "What exactly is water and airbending?"

Both benders looked to him as Katara then explained, "You see, Steve, our world is comprised of Four Nations. The Water Tribe," she pointed to herself as a representative. "the Air Nomads," Aang proudly points to himself as he then said, "the Earth Kingdom," Katara looks a little sullen as she said, "And the Fire Nation."

Both Aang and Steve notice how upset she was starting to look. When Steve tried to say something to ease her mind, but Gran-Gran come up from behind and said, "All right, no more playing." Beckoning her granddaughter she then said, "Come on, Katara, you have chores."

As the two walked away, Katara then excitedly tells her grandmother, "I told you, he's the real thing, Gran-Gran. I finally found a bender to teach me."

They stopped amongst the tents as Gran-Gran told her, "Katara, try not to put all your hopes in this boy."

"But he's special. I can tell." Katara argued. She felt excited as she said, "I sense he's filled with much wisdom."

See looks back to Aang, who now has his tongue stuck to his staff. The children giggled as he said oddly with his tongue stuck, "See? Now my tongue is stuck on my staff…" The little boy closest to him then pulled on the staff. This makes the other children giggle as Aang grunts from the slight pain. Then he puts on a boy-do-I-feel-kind-of-stupid-face from it. Steve slightly smiles at the antics.

On Prince Zuko's ship during the day, the prince stood before two Fire Nation soldiers in a triangle as his uncle watched from the side. His uncle instructed, "Again."

With a grunt, Prince Zuko threw a few fire fists as the soldiers who used their firebending. The flames whooshed by as both soldier threw a fire fist of their own. Prince Zuko dodged under one with a twist as he then jumped over the second fire flow. As he flew through the air, he extended his left fist and shot a blast of fire at the soldier on his left. The soldier jumped up as the fire hit the deck of the ship. As Zuko came down, he swept his leg and a stream of fire at the other soldier who was able to jump out of the way. All three of them take a stance with Zuko's arms stretched out.

With a groan, his uncle stands up and said, "No!" Prince Zuko looks to his uncle as the man said, "Power in firebending comes from the breath," He said as he took a breath while raising his hands to demonstrate, "not the muscles." He brings his right arm back as he stretches out his left, "The breath becomes energy in the body." He puts his hands to his stomach as he continues to explain, "The energy extends past your limbs and becomes fire." Then he takes another deep breath and throws a fire fist at the Prince, but makes sure that it doesn't go to far to hit the teenager. With strict discipline he said, "Get it right this time."

"Enough!" Prince Zuko snapped. He came closer as he felt tired of the sequence and said, "I've been drilling this sequence all day." Being impatient he ordered, "Teach me the next set. I'm more than ready."

"No, you're impatient." His uncle told him. Then acting like a teacher he said as he sat back down, "You have yet to master your basics. Drill it again!"

Growling in irritation, he then grunts as he kicks a fireball at one of the Fire Navy soldiers. The soldier tried to block it, but it was so sudden that it knocked him down with a grunt of his own. Turning back to his uncle, Zuko then said, "The sages tell us that the Avatar is the last Airbender." His uncle only gives his nephew/pupil a stern look as Zuko said, "He must be over a hundred years old by now. He's had a century to master the four elements- -" His uncle's expression didn't change as Zuko said, "I'll need more than basic firebending to defeat him." The Prince then snapped as he ordered, "You will teach me the advanced set!"

Knowing that his nephew's impatience would make him go on like this, his uncle gave in and said, "Very well." His tone and face changed when he said, "But first," he leaned over and picked up a bowl of something, "I must finish my roast duck."

Prince Zuko could only look in slight uncomforting as his uncle happily made noises as he shoveled the pieces of duck with chop sticks, "Mm, mm."

Back at the village, Sokka spoke to a few people, "Now, men, it's important that you show no fear when you face a Firebender." Then pulling out his club he said, "In the Water Tribe, we fight till the last man's standing. For without courage, how can we call ourselves men?"

As it turned out, the 'men' he was talking to was a group of six little boys. One of the boys didn't look all that interested as the others didn't know what to say. Finally one of the boys raised his hand and said, "I gotta pee!"

"Listen! Until your fathers return from the war," Sokka said as he tried to prepare them, "they're counting on you to be the men of this tribe. And that means no potty breaks!"

But the boy sounded really serious as he said, "But I really gotta go!"

Sokka sighs in defeat as he then asks, "Okay, who else has to go?"

All five of the other boys then raised their hands. Sokka looks down at them in disbelief and then groans when he facepalms. As the boys leave, Steve comes up to Sokka and said, "If it makes you feel any better, I actually thought that you sounded pretty convincing for a warrior."

"Thanks. That does actually made me feel a little better." Was all Sokka said. Katara came up to the both of them and asked, "Have either of you seen Aang? Gran-Gran said he disappeared over an hour ago."

Speaking of said Airbender, young Aang was just emerging from a bathroom like igloo. Laughing he said, "Wow! Everything freezes in there."

All the children start to laugh as they come up to him. Sokka groans as he looks to his sister and said, "Ugh! Katara, get him out of here! This lesson is for warriors only."

Just as Sokka was about to walk away a child screamed, "Whee!" This makes the siblings and Steve look. They look to see that Aang had Appa's tail suspended over a sawhorse made from a few sticks and Sokka's spear. And the kids started to slide down the tail and shortly flew in the air as they then landed in a huge pile of snow. Steve smiled as Katara giggled from seeing it. Sokka, however; wasn't in the mood as he ran over and shouted, "Stop! Stop it right now!" Looking at Aang and he angrily said, "What's wrong with you?! We don't have time for fun and games with the war going on."

This makes both Steve and Aang curious as the latter asks, "What war?" Jumping down he asks, "What are you talking about?"

"I'm starting to wonder too." Steve said to himself as Sokka asked, "You're kidding, right?"

Before Aang could say anything else, he saw something in the distance that brought a huge grin to his face. Jerking his head back a little, making the three in front of him flinch, the Airbender then shouted, "Penguin!"

The other four looked behind them and saw that there was a penguin behind them. As Steve took a closer look, it didn't look like a penguin from his world. This one didn't have a beak, but it did have whiskers, four flippers and a huge tail. The penguin suddenly becomes scared of something and then with a few squeaks and squawks, the penguin turned and waddled away. Not wasting another second, Aang took off like a rocket after the penguin.

"He's kidding… right?" Sokka asked. Katara and Steve could only give him an unsure look.

Katara and Steve had Aang who had followed the penguin to a place where a whole flock of them. As they walked through the black and white bodies, Steve couldn't help but wonder in amazement about the things that he's seen here. But he put his effort into finding the young Airbender as Katara called out, "Aang?"

They didn't have to search for very long as they could hear him laughing. Aang kept laughing as he wasn't having any luck trying to catch a penguin, but couldn't seem to grab one as he said, "Hey come on, little guy." Turning to another one he asks, "Want to go sledding?" As he chases the waddling creature he trips and falls with a grunt.

Both Katara and Steve catch up to him as he used airbending to right himself. Chuckling he said, "I have a way with animals."

"That I can believe." Cap told him. Aang then does a funny thing and starts to waddle and make squawking noises. His friends laugh at the silliness. Katara then said, "Aang, I'll help you catch a penguin if you teach me waterbending."

Aang had grabbed a penguin by the tail and was being dragged by it, and when he let it go, he turned to her and said, "You got a deal!"

"Uh, Aang. Don't you think that might be a little difficult with just one little problem." Steve tried to make him see reason which he did. Katara looked a little bummed as Aang said while using airbending to put himself on his knees, "He's right; I'm an Airbender, not a Waterbender." Standing up he asked, "Isn't there someone in your tribe who can you?"

Steve and Aang watch as her face becomes downcast as she turned away and said, "No. You're looking at the only Waterbender in the whole South Pole."

"This isn't right. A Waterbender needs to master water." Aang said as he thought that it wasn't fair for Katara. Then he thought and said aloud, "What about the North Pole? There's another Water Tribe up there, right"

"Yeah. Maybe they have Waterbenders who could teach you." Steve put in. Katara wasn't as sure as she said, "Maybe. But we haven't had contact with our sister tribe in a long time. It's not exactly "Turn right at the second glacier." It's on the other side of the world."

"But you forget, I have a flying bison." Aang reminds her, an idea forming in her head. He then says as he makes an offer, "Appa and I can personally fly you to the North Pole. Katara, we're gonna find you a master!"

Katara wasn't sure as she said, "That's… I mean, I don't know. I've never left home before."

"Well, you think about it." Aang said, letting her come to the decision. His face perked up when he said, "But in the meantime, can you teach me to catch one of these penguins?"

With a smile Katara started to reach into her pocket and said, "Okay, listen closely my young pupil." With a humorous bow, she said, "Catching penguins is an ancient and sacred art." She then revealed that she had pulled a tiny fish from her pocket and said, "Observe." Katara then throws the fish to him.

This causes all of the penguins nearby to start squawking as they waddled over to get the fish. Aang catches the fish as the penguins waddle up to him. He giggles as the start to pile up on him. He laughed out loud as the penguins tried to get the fish.

Not too much later, both Aang and Katara were on the backs of penguins sledding down a slope. Both of them shout happily as they flew off of a cliff. When they landed, they look back to see Steve flying off the cliff using his shield since he didn't feel like riding a penguin. He quickly catches up with them as they continue down the slope. All three of them laugh at the fun. As they go through a strip with high walls, Aang moves to what looked to be a ramp and slides off of it, followed by Steve. As they fly over Katara's head, both she and Aang look to Steve as he did a spin on his shield. Aang laughs at the fun they were having as he lands in front of Katara.

All three make noises of excitement as they continue down the slopes. As they come together on their 'sleds' Katara yelled while laughing, "I haven't done this since I was a kid!"

"You still are a kid!" Aang shouts back. They slide towards a mound of ice that had many tunnels in it. Katara took the lead in one of the tunnels as Aang and Steve followed her in. In the circular tunnel, they start to weave to where they could slide on the side. Using his airbending, he shot ahead of Katara and Steve.

Soon they came out of the tunnel as the penguins and shield slowed down. As they came to a stop, Aang and Katara got off the backs of the penguins as Steve got off the shield. As the penguins waddled away, Cap used his foot to make the shield flip up in the air. He caught it in his hand as it came down and placed it on his back.

Their attention was grabbed by something nearby. The three of them walk up to it and look up at the full height. Aang simply said, "Whoa!"

"What is that?" Steve asked as the thing they saw was a giant metal ship. Katara was didn't sound too happy as she said, "A Fire Navy ship… and a very bad memory for my people."

After a moment of looking at it, Aang started to walk towards it. Katara tried to stop him, "Aang, stop! We're not allowed to go near it."

"Why? It doesn't look like it's been used in years." Steve argued. Katara gave a pretty good reason, "Because the ship could be booby-trapped."

Aang turned around and told her, "If you want to be a Bender, you have to let go of fear."

Katara was still hesitant, as was Steve, but taking a chance the two of them followed Aang inside. They quickly joined Aang before they went inside. As they continued to walk towards the spooky ship, they couldn't help but feel a little frightened at the enormous size. Climbing up the ice that kept the ship aground, they made their way through a hole in the ships hull. Very carefully the two made their way inside the ship. They passed by many doors as they walked through the dark, cold hallways of the ship.

Taking the time as they walked through one corridor after another, Steve decided to ask Katara, "I've been wondering about a few things, Katara."

"Hm?" She said as she looked back. Steve then asked, "Last night you said something about someone called the 'Avatar', what is that exactly."

"Well, to put it simple terms, the Avatar was the protector of our world. The Avatar would watch of the Four Nations and step in when things got out of hand." Katara explained. Steve nodded as he started to understand a little more. Both of them, however; didn't seem to notice that talking about the Avatar made Aang feel uncomfortable. The three of them passed by a few more rooms as they continued to explore. As they passed a ladder that went up to another level, something squeaked from above. Steve walked up beside them and said, "Probably just a rodent. So hopefully nothing to worry about." With that little bit of reassurance they kept moving.

The three friends made their way into a room with weapons. Aang walked right in the room with the other two behind him. As they looked around, Katara told them, "This ship has haunted my tribe since Gran-Gran was a little girl. It was part of the Fire Nation's first attacks."

Aang looked over the sharp weapons with uncertainty. And when she mentioned the 'war', he was still very confused, "Okay, back up." He moved through the room as he stated, "I have friends all over the world, even in the Fire Nation." He picked up a spear as he said, "I've never seen any war."

This made both Katara and Steve confused as the former asked, "Aang, how long were you in that iceberg?"

"I don't know." Aang said as he started to put the spear away, "A few days, maybe?"

"I think it was more like a hundred years." She said with realization. Aang looked at her with a look as if what she said was ridiculous, "What? That's impossible. Do I look like a hundred and twelve-year-old man to you?"

"I wouldn't say that it's entirely impossible." Cap said was he came closer. Pointing to himself he said, "I mean look at me. I may look young, but I too was once frozen in ice for nearly seventy years."

This shocked both young Benders as Aang said, "Really?" He looked Steve and asked, "But how are you—"

"Still alive." Steve finished. He explained himself, "It was probably in the super soldier serum that made me into what I am now."

Pushing the shocking revelation behind them for now, Katara turned to Aang and said, "And think about it. The war is a century old. You don't know about it because, somehow," Aang's face becomes one in shock as he realizes that she was right, "you were in there the whole time. It's the only explanation."

Now distraught, Aang puts a hand to his head as he backs up to the wall. Sliding into a sitting position, he said, "A hundred years!" Katara and Steve came and knelt by Aang's side as the boy said, "I can't believe it."

"I'm sorry, Aang." Katara said as she put a hand on his shoulder. Steve did the same as he said, "I know how you feel, to be honest." Aang and Katara looked up to him as he said, "After I had been thawed out, I woke up, and the people who had brought me out of it, they tried to make it seem as if I were still back in nineteen forty-two. But I was able to figure it out and I too became distraught about." He frowned as he thought of Peggy and all those who had died after the war, but then he smiled and said, "But I was able to move past it."

"He's right, maybe there's a bright side to all this." Katara added to cheer the Airbender up. Aang's frown turned into a smile and said, "I did get to meet you." He looks to Cap and then said, "Both of you."

Steve and Katara both smiled graciously at this. Standing up, Katara then helped Aang up and said, "Come on, let's get out of here."

With that said, all three friends walked out of the room.

Near the top of the ship, the three were still exploring. But Katara felt that they had been here long enough and said, "Aang, Steve, let's head back. This place is creepy."

Never the less, they still walked into the room. As he went in further, Aang felt something on his foot. Looking down he saw that something was moving as he lifted his foot. Steve then noticed it too and shouted, "Stop! It's a tripwire!"

But the warning came too late as Aang's foot had pulled on the string. Behind them, a trap door fell down on the opening, causing the three to gasp. They ran up to it as Aang asked, "What's that you said about booby traps?"

More sounds could be heard from inside the room, and they gasped when they saw a few inner workings pulled a few chains. When thing led to something that was made of flint and it sparked something. They gasp as a lot of steam came out of pipes. In what sounded like a miniature explosion, a signal flare whizzed up into the sky. The soldier and the benders look out the window, with Aang saying, "Uh—oh."

The signal flare went high into the sky, where it could be seen by all. Looking up to the ceiling, Aang saw a hole and ideas started to form in his head. Turning to Steve he said, "Put your shield under the hole and I can airbend you and Katara out." Steve was about to say something when Aang beat him to it, "Then I'll come up next."

Trusting the Airbender's word, Steve took his shield off of his back and placed it down under the hole and stood on the underside of it. Holding his hand out to Katara he said, "You might want to hold on tight."

Katara joined him on the shield, and then with a twist of his hands, he created a small yet powerful tornado that lifted them out of the ship, making Katara shriek a little. As Cap moved out the way in midair, Aang used his airbending to jump out of the ship after them. Aang joined the two as Cap placed the shield back on his back. Taking Katara from there, both Airbender and super soldier carefully jumped from spot to spot down the ship.

As he viewed the flare from the telescope, Prince Zuko makes it go down to see what caused it. He then saw three figures; a tall man dressed in blue, what appeared to be a Water Tribe girl, and his good eye grew large from what appeared to be a boy in Air Nomad attire as they jumped down.

"The last Airbender." He said with determination. He then commented, "Quite agile for his old age."

Turning to one of the Fire Nation soldiers behind him he ordered, "Wake my uncle! Tell him…" He looks back to where he saw the Airbender as he said, "I found the Avatar…" He looks through the telescope again and looks to see where he was going. Unfortunately, he saw something, "… as well as his hiding place."

Moving his eye away from the telescope, he narrowed them as he felt like his search would end soon.

To Be Continued…
