The Promise Chapter One

I don't own Digimon or Avatar: The Last Airbender

The Promise

"Water, Earth, Fire, Air. Long ago, the four nations lived together in harmony. Then everything changed when the Fire Nation attacked. Only the Avatar, master of all four elements, could stop them. But when the world needed him most, he vanished from the world never to be seen again for one hundred years until the new Avatar, an Airbender named Aang was found by two members of the Water Tribe, Sokka and his sister Katara. They also found a young girl named Daisuke who didn't remember anything but her name and together they travelled the world to help Aang learn the four elements so that he could defeat the Fire Lord.

And with the help of his friends, that happened. Aang defeated Fire Lord Ozai and ended the hundred year war. Zuko the son of Ozai, became the new Fire Lord while Daisuke married him becoming the new Fire Lady. Together with Earth King Kuei, Aang, Zuko and Daisuke promised to restore the four nations to harmony.

"I never realised the Fire Nation has built so many colonies in the Earth Kingdom," Aang said as he, the Gaang and the Earth King were looking at a map of the Earth Kingdom on the wall while Momo was looking at Bosco's hat.

"Yes. For the people of the Earth Kingdom, they're a constant reminder of the War, like an old scar." said the Earth King before looking at Zuko and his eyes widened slightly. "Oh, I….I- Fire Lord Zuko, I meant nothing personal."

"It's fine Earth King Kuei. You're right. After all the pain my father has caused, it's my duty to bring healing to the world. I'll remove these colonies. I'll do whatever it takes." Zuko replied as Daisuke held his hand and gently squeezed it while smiling at her new husband who she had married a month after the defeat of Fire Lord Ozai.

"And I'll help you do that," she said.

"But removing the colonies won't be easy. A lot of people's lives are gonna be disrupted. We need someone to oversee everything, to make sure it goes peacefully. Someone like me!" Aang said with a smile making Zuko and Daisuke look at him.

"You'd really do that?" Zuko asked.

"Of course, I'm the Avatar! Making stuff go peacefully is kind of my thing," he answered with a smile.

"Wonderful! The Avatar's personal involvement will give the entire process an air of hope!" The Earth King said.

"Sokka and I can help!" Katara said while Sokka frowned.

"Aw, I was going to go visit Kyoshi Island," he whined, the Earth King was in thought making everyone look at him.

"It'll be a movement, a movement towards harmony. We will call it….the uh…." he said trying to think of a name.

"The Harmony Restoration Movement!" Sokka said enthusiastically making Toph look at him.

"The Harmony Restoration Movement! I like it!" The Earth King said with a smile.

"What's with you and your goofy names for everything?" Toph asked Sokka who grinned.

"It's a gift," he answered.

"Right sure it is," Toph replied making Sokka pout. Later that day after the meeting with the king, Aang, Sokka, Suki and Katara were on Appa while Daisuke and Zuko were on Flame flying beside the Sky Bison as both flew through the air as night began to fall.

"I thought the Earth King's celebration didn't start for a couple more hours," Zuko said.

"It is but we wanted to take a ride on Appa before that," Sokka replied as Appa dived down with everyone cheering while Flame followed suit making Daisuke, Zuko and Toph scream in either excitement or fright before Appa and Flame rose up into the air.

"Wahoo! Let's go again!" Aang cheered before Suki pointed into the night sky.

"Wait you guys the fireworks are starting!" she told the others and sure enough fireworks were being launched into the sky exploding in an assortment of colours as the Gaang looked on in awe.

"Wow. The view is amazing," Katara said.

"It is! Thanks buddy," Aang said to Appa who roared in reply.

"Wahoo! Yeah!" they heard the sounds of Earth Kingdom citizens celebrating down below.

"Well it sounds like the Earth King announced the Harmony Restoration Movement," Daisuke said looking at the fireworks.

"Hey, wanna know what fireworks are like for me?" Toph asked Zuko who looked at her. "Close your eyes," she said and Zuko did so.

"Boom!" Daisuke shouted making Zuko scream in fright while Daisuke and Toph laughed. "Anyway, don't be such a grump Toph. You're out with your friends on a beautiful night, celebrating the fact that we saved the world," Daisuke told her.

"I guess you're right sis," Toph replied punching her sister in the arm.

"You, too. Your new Majesty Fire Lord Zuko sir! Turn that frown upside down! It's happy time!" Aang said looking over at Zuko who had a small frown on his face.

"Zuko?" Daisuke asked concerned.

"I visited my father in prison the other day...I've been meaning to ask you for a favour Aang," Zuko said.

"Sure, anything," Aang replied with a smile.

"If you ever see me turning into my father, I want you to...I want you to end me," Zuko said.

"What!?" everyone shouted in shock.

"Zuko are you nuts? What about Daisuke you just married her are you really going to ask me to kill you and rob your wife of happiness and her love?" Aang asked.

"Even now, after everything that's happened, my family's legacy is still a part of me. That's why it's my duty to heal the scars that the Fire Nation has left on the world. But the Fire Lord's throne comes with a lot of pressures. And if I'm honest with myself...I need a safety net. The world needs a safety net. That's what I need you to be, Aang. The safety net." Zuko answered.

"But you're not your father Zuko! You're my friend how can you expect me to…" Aang was cut off when Zuko spoke again.

"As your friend, I'm asking you if you ever see my go bad, end me. Promise me, Aang." Aang frowned and looked at the others who all had sad expressions on their faces and he turned to Katara who nodded and he sighed heavily.

"Fine….I promise," Appa and Flame continued to fly through the air as the fireworks continued to explode but the Gaang were no longer in awe.

-One Year Later: The newly built Royal Palace in the Fire Nation Capital.

Zuko and Daisuke were in their chambers in the newly built palace sleeping peacefully until Zuko heard a slight noise and carefully slipped out of the bed leaving his wife undisturbed, he ran out of their room looking down the hallway. "Who's there?!" he quietly shouted but nobody answered. "I'm getting paranoid," he mumbled heading back to Daisuke who had noticed her husband's absence and was waiting for him to return.

"Down with the traitor! Down with the Fire Lord who betrays his own people!" A feminine voice shouted as a masked warrior emerged from the shadows attacking Zuko who stepped back as she threw a chain that had a mace made of earth attached to it which wrapped around Zuko's legs tripping him and he landed on his back, the assassin then stood over Zuko. "I will not allow you to destroy my home traitor," she told him before a blade was held to her throat.

"Don't move." the assassin turned and saw it was Daisuke holding one of her meteor hook swords. "You alright Zuko?" she asked her husband.

"Yeah, thank you," he answered standing up and removing the assassin's mask. "Convince me not to take your life," he told her.

"Go ahead! My family has been loyal to yours for generations! By getting rid of me, you would simply complete your betrayal!" the assassin shouted.

"What's your name?" Daisuke asked causing the assassin to glare at her.

"Not that it won't be said for much longer, my name is Kori and my father is the mayor of Yu Dao."

"Yu Dao….the first of the Fire Nation colonies." Zuko said.

"Yes, my home! And now you and the Avatar are going to destroy it with your precious Harmony Restoration Movement!" Kori said making Zuko look at his wife who nodded slowly putting her hook sword away before some guards arrived and took Kori away.

"We'd better take her back to Yu Dao, I want to stop any problems before they become too big to end peacefully," Zuko said and Daisuke nodded as both headed back to bed. Several days later in the city of Yu Dao, two Fire Nation soldiers walked behind Kori who was now in chains and they continued walking until a man wearing noble robes ran over.

"Stop, stop!" he shouted as Kori was pushed towards him. "Kori! Where have you been!? Your mother and I have been worried sick!" he told Kori before looking at the two soldiers behind his daughter. "Wait—who are these men? And why are you in chains?" he asked worried.

"I went to see someone about our current problem father," Kori answered.

"Who?" he asked as Kori glared behind her.

"Him." She snarled and her father looked and gasped seeing Daisuke and Zuko wearing their Fire Lord and Fire Lady robes approaching.

"Fire Lord Zuko and Fire Lady Daisuke!" he exclaimed.

"So you're Mayor Morishita." Daisuke said. "Your daughter snuck into our home and tried to kill my husband," she informed the mayor who looked at his daughter stunned.

"Kori?" he asked.

"Someone had to do something!" Kori answered before her father got on his knees and bowed in front of Daisuke and Zuko.

"My sincerest apologies for my daughter's rash behaviour, Fire Lord! Have mercy!" he begged.

"I should have this entire village burned down," Zuko threatened before Kori got in his face.

"Why bother? The Harmony Restoration Movement will accomplish the same thing without you having to lift a finger!" she shouted angrily.

"Why can't you colonials get it through your thick skulls?! The Harmony Restoration Movement is a means to peace!" Zuko shouted back as the mayor stood up.

"P-peace?! Peace for whom?! With all due respect, Your Majesty, my family has lived on this land for generations! This city was built on our blood and sweat! We have as much a right to be here as anyone else!" He told Zuko and Daisuke.

"You're Fire Nation citizens! You should live in the Fire Nation!" Zuko replied.

"You're right, Fire Lord! We are Fire Nation citizens! And I'll tell you this – your father would never have let the Avatar and the Earth King bully him into something so obviously bad for his own nation's citizens!" Mayor Morishita said making Daisuke and Zuko share a glance as they thought back to when they visited Ozai after Zuko was crowned Fire Lord.

-Flashback Begin-

Ozai was sitting in his cell leaning against the wall in the prison when the door opened and Daisuke and Zuko walked through and looked at him.

"I should count myself lucky. The new Fire Lord and his traitorous wife grace me with their presence," Ozai sarcastically said.

"You should count yourself lucky that the Avatar spared your life," Zuko told him. "And who I choose to marry is none of your business, I love Daisuke with all my heart, and nothing you say will change that," Zuko told him.

"Banishing Zuko was the best thing you could have done for his life. It put him on the right path. Perhaps your time in here could do the same for you," Daisuke told him.

"Why are you two really here?" Ozai asked them.

"Because you're going to tell us something. Where is my mother?" Zuko asked making Ozai smirk.

"You ought to bring me some tea, Zuko. We'll talk while sipping from steaming little cups, much like you did with my traitorous brother. I'll give you advice on how to be a good Fire Lord. Wouldn't that be nice? Perhaps even the subject of your mother will come up." He answered before Daisuke frowned.

"Come on Zuko, we don't need his help to find your mother or how for you to be Fire Lord," she said and Zuko nodded and both began walking out of the room before Ozai spoke up again.

"Do you think being Fire Lord is easy?! The throne comes with many pressures, and those pressures will change you! But if you can stand the heat, you'll become something more. Of all the people in the world, I have the wisdom you need, the wisdom of experience! Be honest with yourself, Zuko – Do you really believe you can handle it all on your own? You'll be back. And I'll be here waiting for you. Son." He said before the door shut behind Zuko and Daisuke.

-End Flashback-

Zuko charged the Mayor pinning him to a wall with his left arm while he held a fire dagger in his right hand. "I'm not my father!" he shouted.

"No, young man. You're not. Fire Lord Ozai had many faults, but he was never a coward. He was never atraitor and he would never marry a traitor either," Mayor Morishita said glaring at Daisuke with hatred. Meanwhile off the coast of the Fire Nation, Aang was flying Appa above a Fire Nation ship which Sokka and Katara were on along with a group of people from another Fire Nation colony while the Mayor of the colony and a few older members of the colonists were on Appa.

"Don't worry, Mayor Nishi! My team and I have helped dozens of Fire Nation colonies move back to your homeland already. They've all loved coming back!" Aang said happily to the nervous Mayor.

"Those colonies were young. Their people had no roots in the Earth Kingdom." She replied.

"Things are different in the Fire Nation now, you'll see! Fire Lord Zuko's reintroducing classic Fire Nation culture to his people. You'll learn so much about your past by living here. And you'll have fun, too!" Aang told her with a smile.

"If you're sure Avatar Aang," Mayor Nishi said and soon Aang, Sokka and Katara were helping to unload when some soldiers marched over.

"Stop! Stop unloading, are you colonials!" the soldier at the front asked Mayor Nish.

"Yes," she answered.

"Return to the Earth Kingdom, by order of the Fire Lord!" the soldier ordered causing Aang to drop some crates he was lifting with his Airbending.

"What!?" he, Katara and Sokka asked the soldier.

"Fire Lord Zuko has officially withdrawn his support of the Harmony Restoration Movement!" the soldier answered.

"We need to go see Zuko and Daisuke right now," Katara told Aang who nodded and he along with Katara and Sokka climbed onto Appa who flew off back to the Earth Kingdom determined to get some answers from Zuko. Meanwhile in the Earth Kingdom outside the city of Yu Dao was Toph's new MetalBending academy where she would train any Earthbender who has the potential of being able to bend metal and her three students who were named Penga, Ho Tun and The Dark One were looking out the window at the crowd gathering at the gates of Yu Dao.

"I wanna know what's happening!" Penga exclaimed.

"Whatever it is, it's bad! Bad! The city is probably doomed! We're probably doomed!" Ho Tun said worried while The Dark One simply sighed.

"I hate doom," he said before Toph stomped sending a pillar of earth up sending her three students into the air before landing the ground with a thud.

"How are you lily livers going to learn MetalBending by staring out a window?! Get back to practice!" she shouted at them.

"Sifu Toph, something's happening in Yu Dao and I wanna know what," Penga said as Toph walked to the window.

"Hm you're right something is going on down there, I can hear it," she said before running out of the building. "I'm going to check it out. Stay put and do your forms! If you don't, you're really gonna get it when I come back!" she then heard Appa roaring as he flew towards Yu Dao and she launched herself into the air with her Earthbending and landed on Appa's saddle. "Hey guys," she greeted making Katara hug her tightly.

"Toph, I can't believe how long it's been!" she said.

"I missed you guys too," Toph replied.

"I heard you started your own MetalBending School," Sokka said and Toph nodded.

"The Beifong Metalbending Academy! You guys just flew over it! I heard Appa, so I had to come say hi!" she answered.

"Wow! Your own school, how's that going for you?" Sokka asked and she shrugged.

"Meh," was her answer as Sokka looked over at Toph's school.

"I'm so glad you're here, Toph. Aang needs all the support he can get right now, because of what he might have to—," Katara said.

"Hey where is Twinkle Toes?" Toph asked before she heard Momo chatter from beside Aang who was on Appa's head. "Oh there he is,"

"Zuko's changed his mind on the Harmony Restoration Movement." Katara said.

"You're kidding…there's no way big sis would let him do that," Toph said.

"We know, but nonetheless. He's holed himself and Daisuke up in Yu Dao with a bunch of his soldiers. He won't let anyone in or out. That's where we're headed." Sokka replied.

"So that's what's going on! The lily livers-I mean, my students were talking about it. Zuko started to act like his old man Ozai then," Toph said. "But I still don't believe it, Daisuke would notice and would stop him before he'd do something like this,"

"We don't know anything yet, that's why we're going to talk to them," Sokka said while Katara looked at Aang who was meditating.

"But Aang's meditating on what he might have to do—because of the promise he made," she said as Aang's cosmic energy met with Roku's.

"You've done your duty. The war is over. And yet the world is still not at peace." Roku said and Aang nodded sadly. "I'm sorry, Aang. You are still dealing with the consequences of my own indecisiveness."

"Avatar Roku, I never should've made that promise to Zuko. I mean I didn't even kill Ozai, and he was evil all the way through. How am I supposed to kill the husband to my Firebending teacher? My friend? What kind of person would I be?" Aang asked.

"A person who keeps his promises. Zuko was in his clearest moment when he asked you for that promise. He knew what was at stake as did Daisuke when her husband asked. All those lives that have been lost in the last hundred years ... I could have saved them. I had so many chances. Sozin almost never had his guard up when he was with me." Roku answered with regret.

"Are you saying you regret killing Fire Lord Sozin?" Aang asked his past life.

"I am," he answered.

"But he was your friend," Aang said.

"More than my friend, he was like a brother to me. But because of him, the world burned. When you are in a position of power, you must put the needs of the world above your own. Zuko, at one time at least, understood this." Roku replied.

"I'll go to Yu Dao and talk to Daisuke and Zuko because we're friends and that's what friends do," Aang said.

"Remember my advice to you Aang, you must be decisive. A promise is a promise," Roku said before he vanished and Aang returned to his body just as Appa landed on the ground outside of Yu Dao behind the crowd who were shouting.

"Fire Nation out! Harmony now!" they shouted, Sokka and Katara then noticed Longshot and on his shoulders was Smellerbee.

"Hey it's Smellerbee, what's he doing here?" Sokka asked.

"You mean what's she doing here," Katara corrected him.

"That's what I said. What's she doing here," Sokka replied making his sister sweatdrop as Smellerbee looked at Aang and smiled.

"Hey everyone it's the Avatar!" she exclaimed and the crowd began cheering for Aang as he walked over. "Aang! We were hoping you would come! So what's the plan of attack? The Freedom Fighters are at your service!" she told him.

"I appreciate your confidence, Smellerbee. But I need to talk to Daisuke and Zuko," Aang replied.

"What?! The time for talking was over as soon as the Fire Lord and his wife broke with the Harmony Restoration Movement! Besides, you're not getting into that city without a fight! Fire Nation troops are everywhere!" Smellerbee shouted.

"I'm sure they had a reason for it," Aang said opening his glider and turning to Katara. "Ready sweetie?" he asked.

"I'm ready sweetie," Katara said as Aang wrapped his arm around her waist and both flew over the wall of Yu Dao.

"Sweetie, seriously?" Toph asked.

"I know right? So oogie," Sokka answered as Aang and Katara landed in Yu Dao with Fire Nation soldiers approaching them.

"Flamio, Hotmen," Aang greeted.

"This city is under the protection of the Fire Lord himself! No one may enter without his express permission, not even the Avatar! Leave now." One of the soldiers ordered them.

"Please I just wish to talk to Fire Lord Zuko and Fire Lady Daisuke," Aang said peacefully.

"You were warned," The soldier said raising a hand to Aang, he then fired a column of fire at Aang who leapt over the attack, he landed and ducked when the solider kicked flames at him. Aang stomped on the ground and raised his arm trapping the soldier's foot with earth making the other soldiers look in shock.

"What're you dolts waiting for? Attack!" the trapped soldier commanded, as the fight was going on Daisuke walked past with Suki in her Kyoshi warrior outfit as her bodyguard and both saw the soldiers about to attack and sighed, Daisuke raised her right arm and launched a stream of golden fire between the soldiers, Aang and Katara as she did this blue lightning began forming around the fire shocking Daisuke and Suki but Daisuke stopped the lightning before it could get out of control.

"Okay what is going on?" Daisuke asked walking towards the soldiers with Suki.

"Suki what're you doing here?" Aang asked.

"I'm Daisuke's bodyguard," Suki answered. "I offered to when I found out about the assassination attempts on her and Zuko,"

"I can't imagine why," Aang said sarcastically as Zuko approached. "Zuko what is wrong with you, why did you withdraw support for the Harmony Restoration Movement?" he asked walking over to Zuko.

"Calm down Aang," Zuko said. "Let's walk and talk I need to show you something," he said turning and walking off with Aang, Katara, Daisuke and Suki following. "Did you know that Yu Dao is the oldest of all the colonies? Many of the Fire Nation families here immigrated over a hundred years ago, when Yu Dao was just a tiny village at the bottom of a valley." Zuko said stopping in front of a blacksmith where an Earth Kingdom young adult was being taught by an elder Fire Nation Blacksmith. "Together with the Earth Kingdom people who were already here, they built all this. Yu Dao now makes the finest metalwork ever produced, using both Fire Nation and Earth Kingdom expertise. This is why this is one of the richest cities in the world,"

"Doesn't seem like the wealth is evenly shared," Katara said watching an Earth Kingdom citizen clean a Fire Noblemen's shoes.

"It's not perfect, Katara, but all the city's people, including the Earth Kingdom people, are better off now than they were a hundred years ago." Daisuke replied.

"The history lesson is great and all, but none of it matters! By betraying the Harmony Restoration Movement, you're going to start another war!" Aang said to her and Zuko.

"Look, Aang, when I came here a week ago, I had planned to personally enforce the removal of Yu Dao from the Earth Kingdom! But then..." Zuko said.

"But then what?" Aang asked.

-Flashback Begins-

"You're going to regret saying that old man, guards seize him!" Zuko ordered the two guards who walked towards Mayor Morishita before a wall of earth erupted in front of them.

"What?" Daisuke asked seeing a woman in a bending stance.

"Fire Lord, please! Forgive my husband's foolishness! I've told him time and time again to control his tongue, but he never does!" the woman said.

"You're Mayor Morishita's wife?! An Earthbender…?" Zuko asked shocked.

"Yes, I'm an Earthbender. As is our daughter." Mrs. Morishita said as a stalagmite rose from the ground breaking Kori's chains and she Earthbent her weapon back to her side only for Flame to pin her to the ground under his leg thinking Kori was about to attack his mother again.

"Whoa easy boy," Daisuke said rushing over rubbing Flame's snout. "I don't think she's going to hurt us again," Flame growled and lifted his leg allowing Kori to get to her feet.

"I may be an Earthbender, but through my father's bloodline I am a Fire Nation citizen! My father taught me to always be loyal to the Fire Nation, to my people. Something you obviously never learned from your father." She spat at Zuko.

"Would your majesty be willing to stay in Yu Dao for a few days? It would be an honour for us to show the Fire Lord and his wife our way of life." Mrs Morishita said bowing to Zuko and Daisuke.

-End Flashback-

"So we stayed." Daisuke told Aang and Katara.

"I saw what my people created here. I saw what the Harmony Restoration Movement would destroy. I changed my mind. Ever since my coronation, I've been having trouble finding peace. Now, I think I've finally figured out why. I'd forgotten about mypeople. I know you defeated the Fire Nation, Aang, but my people still deserve respect!" Zuko told Aang.

"I defeated the Fire Nation?! You mean we defeated the Fire Lord!" Aang replied frustrated.

"It'd be disrespectful to take from them a life they spent generations building! I won't let you do it!" Zuko said.

"Harmony requires four separate nations to balance each other out! You can't have balance if one nation occupies another!" Aang shouted.

"Aang this could be an exception," Daisuke told him,

"What?" Aang asked her.

"Exceptions should be made for all the remaining colonies! Most of them have been around for well over a century. They're older than you, Aang!" Zuko told him.

"You've got to be joking. That would make peace impossible!" Aang replied as Katara got in between the two of them.

"Well, regardless, the Earth King needs to be a part of whatever happens next. If Aang and I can arrange a meeting, will you be there, Zuko?" she asked the Fire Lord.

"I'll be there," Zuko said.

"Talking is good I guess," Aang replied walking off and Zuko walked off another way, Daisuke and Katara both sighed at how the two boys they loved were acting.

"Dai how can you support Zuko's decision when you know it's wrong?" Katara asked making Daisuke sigh and reply.

"Maybe it is wrong or maybe it isn't but no matter what I'll stand by my husband's side. Besides this is part of being Fire Lord, if he makes a few mistakes he needs to learn from them." She then turned and walked off with Suki following her and they soon passed a merchant who was talking to a customer.

""Sorry man but my supplier was again attacked in the mountains. So I still don't have what you need." The merchant said.

""Was it that fire-breathing monster again?" the customer asked which caught Daisuke's attention as she stopped and listened to the conversation as the merchant nodded.

"Yeah it's the third time this week. Man if this keeps up I'll be put out of business or at least will have to find a new supplier who doesn't have to go through those mountains."

"Suki follow me. I need to check those mountains," Daisuke said walking off and Suki followed who was confused.

"Why?" she asked as they found Flame beside the gate to Yu Dao who walked over to his mother and her bodyguard.

"I think that fire-breathing monster might be a dragon," Daisuke replied climbing onto Flame and Suki who was shocked climbed on also and Flame took off toward the mountains.
