Author's note (not necessary): If some of you readers have wondered what are the differences between original series and this, I'll explain them now.
Several characters have combined elements. For example Sokka is able to use chakra, though he is still fond to science, which he will use in his own ninjutsu. Katara is more experienced in waterbending, but she still needs practicing. Naruto is able to bend air, but instead of Ba Gua, Naruto's style is based on white crane of shaolin, which has same principles.
Tailed Beasts are originally benevolent creatures, but because of the war some have lost their sanity. For example the genocide of Air Nomads drew Hacua into madness, making him slaughter Fire Natives until being sealed.
Instead of the amount of tails and animal characteristics, Beasts names have a relation to elemental bending
Noquan: Nanquan, term used to describe southern kung fu styles, which earthbending is based on.
Zolin: Shaolin, martial art used to inspire firebending
Lueba: Liuhebafa, also known as water boxing. Not used in the series.
Boodfa: Buddha, inspiration to avatar and avatar cycle.
Dackmey: Bak Mei, also known as white eyebrows, is a martial art with shaolin origins. Similar to dragon kung fu. Not used in the series
Zinfi: Xing Yi, a style with same principals as Ba Cua and Tai Chi, but more aggressive. Hints in air- and firebending
Honkar: Hung gar, martial art used to inspire earthbending.
Taeji: Tai Chi, martial art used to inspire waterbending
Hacua: Ba Gua, martial art used to inspire airbending
Haku stood in the outpost of the village. He was nervous. Katara and Sokka should have been home by now, yet they were still out of sight. "When they get back here, they'll better have a good reason for staying at the waters for this late" He thought. Suddenly a large animal swam towards. Haku readied to defend himself, but soon he also saw Katara and Sokka on its back with a bald arrow-headed boy wearing a some kind of uniform riding it. Haku started waving his hands.
The boy, Aang, was first to see him. "There is a girl waving at us. Do you know her?"
"Yes, he is Haku." Sokka answered sarcastically. "And you heard right. Believe it or not, he's a boy"
"Umm, Okay" Aang said making a strange face.
Katara laughed seeing Aang's face. "Don't worry. He isn't much weirder than you are. Besides he is a great storyteller and an incredible fighter"
"But he is nothing compared to Zabuza" Sokka continued. "He can destroy a fire nation ship with one move"
"Well, I believe you." Aang said. "What about Zabuza's stories?"
"Stories?" Sokka asked with a confused look. "Real men don't tell stories, so neither does Zabuza!" He answered going macho. "Okay, so Haku does, but who does count him as a ma-gulrgu!"
Sokka couldn't finish, because Katara suddenly stuffed a string of water in his mouth. Aang laughed a bit and continued riding Appa, the Flying Bison. It didn't take long to arrive to the village. When they did, Haku came to them looking very angry. "I said clearly, that you'll have to come back before sun starts setting and now it has almost set!" He scolded. "And who is he? I sent two with a boat to fish and three comes back riding a giant seal."
"Let me explain." Aang interrupted "I'm Aang, an airbender and avatar from Southern Air Temple, and this is Appa, Flying Bison and my best friend"
Haku however didn't believe. "Those were the worst lies I have heard in years. For you to know, both airbenders and Flying Bisons are extinct. They were killed to the last one in the hands of the Fire Nation"
Aang stood silently looking at Haku. The he started laughing. "You were right Katara, he is a great storyteller!" He said falling into snow from the laughter. "If that was true, It would have meant that I slept a hundred years!"
Katara looked sadly at ignorant Aang before speaking. "I'm afraid Haku is telling the truth, Aang. Around hundred years ago, Fire Nation got militarily stronger than the other nations. The first thing they planned was to destroy the avatar, who they saw as their biggest threat. It is unknown how long it took for them to kill everyone but nonetheless it was done.
Aang's face turned from amused to shocked. "No, that's not true! That's impossible!" He denied, but looking at Katara's eyes, he saw no sings of lies "Excuse me, I'll have to think about this" He said taking his staff and turning it into a kite-like form. All three just looked when Aang left to the sky Appa following him.
Both Katara and Sokka looked angrily at Haku. "Was that really necessary, Haku?" Katara asked.
But before Haku could answer, Zabuza interrupted. "It wasn't the smartest thing to do, but we don't have time to worry about that." He said pointing at the sea. A Fire Nation ship was coming straight towards the village. "We must concentrate on protecting the village. Katara and I get others to safety, Sokka and Haku, you go get your equipment's. We will all meet in this place in three minutes."
Everybody hurried in their own directions. After a while everybody was hiding in or behind huts farthest from the coast, except for four warriors currently waiting the coming of the enemy.
Sokka wore a lighter costume with a mask of seal made of paint and two clubs made of bone. Haku also wore make-up, except completely white excluding the eyes painted red. His battle dress had several straps full of needles, but in hands he had two fans. Zabuza and Katara kept what they had on. Ship came closer hitting the coast. A hatch opened revealing several warriors in red armors led by a boy with scarred left eye.
"Where is the Avatar?" The boy asked.
"You came too late" Zabuza answered. "He left before you came and disappeared to the sky. What I suggest is that you leave this place immediately."
The boy just laughed at them. "Leave? We outnumber you easily. Men, attack!"
Warriors started performing fire, but suddenly fell to the snow. Haku had thrown several needles, pulled the strap for fresh ones and grabbed the fans he had thrown upwards.
Boy looked surprised at them. "I guess you have iron in your words. Uncle Iroh! Kurenai! I need some back-up!
Another older man followed by a woman in her thirties and four kids.
"Here is the plan everyone" The old man, apparently Iroh, started. "Zuko and I take care of the man with the sword. Kurenai targets the kyoshi warrior. Kids take care of those two."
"What about me, daddy?!" Asked one of the kids from Iroh.
"Just do what you normally do, Naruto." Zuko answered for Iroh. "Stand there and look stupid."
"Got it, Zuko! HEY!" Naruto yelled after realising, what Zuko said.
But nonetheless the battle had started. Iroh and Zuko came from different sides of Zabuza, planning to surround him. But Zabuza was used to deal with attacks like this. He grabbed his sword, swung it fluently and thrusted it into the ice. A large geyser stroke underneath Iroh, who barely dodged it. Zabuza didn't at first concentrate on Zuko, seeing him only as a dog, who doesn't bite. Soon however he found out he was wrong, after several fireballs came from his direction. After dodging them, Zabuza ran towards the hole, where the geyser came from, and jumped in it, standing on the surface on the surface. He performed certain moves with his right hand and others with his left hand, creating two whips of water. Now Zabuza had the upper hand, but how long.
Haku on the other hand had some problems. For some reason he got himself captured by a large cherry tree, grown out of nothing. "This Kurenai must be a great life-controller" He thought. "I must think something fast". But he didn't have time, because Kurenai suddenly appeared out of the tree.
"It is a shame you will die here, young kyoshi" She said. "You had potential of becoming a great ninja, but now your friends will see you die"
Suddenly Haku snapped. Friends! He hadn't seen his friends anywhere and he wasn't even in the same place. An illusion! After realising that Haku blocked Kurenai's kunai with his hand, that wasn't bound at all. Soon they were both back in the village, looking at each other.
"Have to say, kid, I am impressed" Kurenai admitted and came again towards Haku. "But the fight is not over"
Meanwhile Katara and Sokka were fighting against three kids. What they could hear from their speech, the girl was Hinata, boy with a dog Kiba and the other boy Shino. All of them used hand-to-hand combat, do Katara got the upper hand. According to Sokka's analyse, Shino wasn't used to fight with his hands, so he must have used something else normally, but it was unclear, what. Hinata on the other hand used mainly a some form of martial art, which utilised chakra, giving even a touch of her dangerous. However she seemed unsure about her strength, weakening her. Kiba was possibly strongest of the team, using his dog to aid him in attacking made him dangerous. He also used spinning attacks making other fly from the strike.
"They are younger and inexperienced compared to us, but if they synchronise their moves they can defeat us." Sokka informed her sister. "You keep those two busy, I'll take care of the dog boy"
Katara did what was told. Kiba started spinning again towards Sokka. Sokka crouched down. When Kiba came spinning towards him, he striked his index and middle fingers into the tornado, sending it towards Hinata and Shino. A large scream of agony was heard, when Kiba went out of control and crashed onto his team-mates.
"What did you exactly do?" Katara asked from his brother.
Sokka thought a moment for his answer. "Better you don't know."
But their triumph was short lived, because both of them flew backwards by a gust. When they looked towards the gust they saw the fourth boy, Naruto, standing on one feet with his arms spread like a bird.
"It took me a while to realise that Zuko just joked." He said smiling. "But now it's time to get serious!"
Naruto made a high kick with his airborne feet, making another gust. But it didn't hit, because it was blocked by another one. Aang had returned and landed between sibling and Naruto.
"Sorry! Meditating took longer than I though!" He apologised from them before turning back to Naruto. "If you are going to attack my friends, you'll have to go through me first!"
But Naruto didn't attack. Instead he looked at Aang confused. "Aang?" Came the name from his lips with a deep voice.
Aang wondered, how he knew his name, he hadn't told it. But even more surprises came, when a large red aura surrounded Naruto, turning his blue eyes into slits. Aang took a defensive position, but it was unnecessary, because the boy talked instead.
"Aang? Is that you?" he asked in a scary, monstrous voice.
But Aang wasn't scared, but surprised, since he recognised the voice. "Hacua?" He asked himself. Katara was also surprised after hearing the name. It was the same as that of the nine-tailed fox of airbending. But could this boy really be Hacua?
Hacua looked at the body he had. "So this is the child Hokage sealed me in." He then looked at Aang. "Yes, it is I, though not in my own body. I'll explain later"
Hacua came on four feet and rushed towards Kurenai, striking her down. Then he made two gusts with his arms, knocking Iroh and Zuko. But he didn't stop there, but kept beating them continuously until stopping.
"You have no right to live!" Hacua yelled at fire people. "This glacier will be your grave!"
"Don't do it, Hacua! Please! Don't do it!" Aang begged with tears in their eyes.
Hacua looked back at Aang. "Why would I let them live!? They killed all of the air people, only to get you! Genocide for genocide is all they deserve!"
Aang was close to bursting in tears "Hacua would have never done something like that! He was my friend, who taught me that nobody is evil! But what you do is evil! YOU ARE NOT HACUA!!!"
Aang started glowing from the eyes, mouth and tattoos and came rushing towards Hacua, hitting him hard. Normally Hacua would have simply blocked, but now he had snapped. He truly wasn't himself. After the genocide, it took him twenty years to be reborn, which after he started his one man crusade to destroy Fire Nation, slaying down armies and even his corrupted siblings. Fight after fight he became more and more insane. All the thoughts came rushing to his mind. But he knew what to do now.
"I won't be able to stay much longer, so I ." He said silently. "They are now too weakened to take you with them so they will retreat. What you need to do now is to find yourself teachers to learn bending from. When the time of the spirits arrive, searh for avatar Roku, he will tell you everything. I will stay here and regain my sanity. I also want you to know, words are not enough, I am sorry." After saying the last words, a tear fell from Hacua's eye. Red aura disappeared and Naruto's unconsious body landed down.
Zuko was first to get up "Now it's our chance. Let's get the avatar"
"No, prince Zuko" Iroh interrupted. "Hacua is right.We are now too weak to fight. You will have your chance later"
Zuko grunted, but understood his uncle was right. All of the fire soldiers limped back to the ship. Iroh however took his time taking Naruto with him.
"No time to take the avatar, but time to take the demon?" Zuko asked, but silenced after Iroh looked at him with a glare, that scared even him.
Aang watched as the ship left and disappeared into icebergs. He sat down. So much had happened in minutes, it was confusing. So much to do and so little time. Aang had planned to play games after leaving the pole, but he wasn't sure he had time anymore. But after Haku suggested that Aang thought about it after some sleep, he agreed.
On the next day members of the tribe helped out with preparing Aang to leave. Katara and Aang prepared to leave, while Zabuza gave the instructions.
"North Pole is in the other side of the planet. There you find teachers for waterbending and ninjutsu. But don't go straight forward, or you get caught more easily. The best way to go is by travelling through the continent of Earth Kingdom, where you can hide in the wast landscape. When you arrive to the North Pole, be careful not to insult anyone. Ninjas hiding in mist are ruthless and love to fight. Katara, before your arrival you must disguise yourself as a boy. Northern water tribe don't allow females to learn waterbending excluding healing. Sokka, now, when you become a ninja, you must know the symbols of each ninja school. Each ninja school uses a certan symbol to show who is enemy and who is ally. If you meet a person, who has an hourglass, rock, waterfall, grass or raindrops, you have met an ally, but if he has a leaf or smoke you have met an enemy. However, there are several schools I don't know. Also some ninjas work as freelancers. They don't use symbols, so watch out for them. To ensure your safety, Haku will come with you."
"What!?" Came Haku's question. "I will stay here! I promised to protect your life, Zabuza!"
"I don't need you anymore." Zabuza said. "When we originally met, I trained you to be my tool. But after I gave up on taking over the North Pole, I kept you as a companion. Finally I saw, that you have a destiny different from my own. Aang is still young and needs all the help he can have. As a last order from me, you'll protect the Avatar."
Haku nodded, understanding the situation and jumped onto Appa. Aang made a sound and the Fying Bison took off. Katara, Sokka and Haku looked down at the village somewhat sadly. On the other hand they were excited for the future journey.
Haku smiled. "Well, I do still have Momo."
Aang turned around. "Who is Momo?" He asked.
"You'll see" Haku answered. "Let us stop in the Kyoshi island for a while."
Aang smiled. "Why not, I have always wanted to ride an Elephant-Koi"
