Hello everyone! Legend355 coming now with another fanfic, as my King of Fighters fic is finally over, the time to adventure myself into new territory has come, and which better one that the greatest cartoon ever made? Yes, today a new adventure for the Gaang starts and against a threat that is much more powerful than Ozai itself!

But first some things to make clear:

This story is 1 year after the comics end, meaning 3 years after the show ended, our favorite air bender is a teenager now! And yeah, I'm taking everything that occurs on the comics here

While I'm considering the comics, I'm not taking into consideration The Legend of Korra here, well, kind of, the thing is that some things that will happen here will not make too much sense if you watched Korra's series, but as that, it has a proper explanation on the fic itself

Speaking about pairings well, I don't want to spoil too much, there will be of course and a lot of romantic moments, but patience will pay, if I tell you which the pairings will be, I will be spoiling you part of the story xD,

On some chapter I will be giving a warning header depending of the situation ocurring on that chapter so you won't get totally caught off guard if the chapter has something that you don't like

With that being said: Enjoy the book 4 of Avatar the Legend of Aang!

…..

"Finally, after so much time, the battle armor is ready."

A dark place, totally covered by any type of machine, tubes and electricity appeared, a blue light was coming from the floor, 2 guys, one of them, being covered by pieces of black metal, being helped by a overweighed mechanic, behind them, a circular and really big metallic object was behind them, then it was turned on, a pink light appeared in the center and expanded on the object

"It is time, the vortex cannot stand more than one people, but with the technology that you have, whenever you go, you will have no problems dealing with any type of masters… even an Avatar."

"I know" said the person inside of the metallic armor, with a really distorted voice -And you know why, even more than this armor itself

An explosion was heard on the distance "The country of Raion depends on you, what the attackers have done to us is unforgivable" the mechanic clinched his teeth "The objectives, correct the unbalance, conquer as much cities as possible and…"

"Kill the avatar and whoever the Fire Lord of that time cares, including himself" the metallic being pressed one of the punches "I'm ready."

"Just be careful, unless is not necessary, don't show more than necessary, unfortunately the machine is unable to go more than 200 years ago, little time after the 100 years' war ended."

"And that's enough for me…"

The metallic being just nodded and went itself inside the portal, the mission was clear, to return a balance but, killing?

Avatar: The Legend of Aang

Book 4: Time

Chapter 1: 3 years later

Even after finishing off the previous Fire Lord: Ozai, things were not totally easy for Aang, the last airbender and the current Avatar, responsible of bringing peace to the world and many other titles, fortunately all those issues were avoided and, while things were not the same as when the war just ended, at least peace was always there

Flying using his blue winged glider, he had a really good sight of the place he was currently visiting: Agni, the capital city of the Fire Nation, the beautiful city constructed on a dormant volcano, alongside him, a strange white creature with wings was flying

"Look all of this Momo, isn't that beautiful?" the animal just made a sound -I know, hopefully Zuko is not busy today

Behind them, an enormous buffalo like animal started to groan

"Appa, all of you finally caught me up!"

"Aang!"

Who was salutating him was one of the most beautiful, and of course, the most powerful water bender in the entire world, Katara, she was not alone, her brother, the weapon master Sokka, the Blind Bandit Toph and the Kyoshi warriors leader, Suki, were with her on the buffalo's loin

None of them changed too much, aside of some details like the girls hairs being longer and some changes on the clothes, the group didn't look really different as when the war ended

"Come on, let's get faster so Zuko will be surprised!"

What was happening right now with the young leader of the fire nation was pretty simple, he tried his best to be a good leader at his age, yet sometimes he needed some time to be alone, after what happened with his ex-girlfriend, Mai, he lost interest on any type of sentimental relationship, friendship was always welcome and of course made him really happy when seeing his fellow friends from other nations, but now, only training himself was important, especially on what he was doing now

Being on the backyard of the Fire Castle, Zuko was able to concentrate, meditate, breath… then he opened his eyes

"Now."

And took his two hands, starting to create a fireball between the two, but the intensity of it, on bright and heat was increasing rapidly, Zuko was sweating, being totally concentrated on the technique

"Come on, it's time to create my own technique, uncle Iroh has done his owns before, now is my turn."

A little spark appeared on the fireball, he was decided

"GO!"

Using his two hands like a cannon, shoot an enormous pillar of fire in direction of the sky, the power of the technique made him really proud and happy

"Yes, I did it, the Fire Cannon is finally mine, if uncle sees it, he would be really happy."

One of his numerous servants appeared on the yard

"Fire Lord Zuko, you have visitors."

"Who?"

"Your friends, Avatar Aang is with them."

"Cool, I will meet them after taking a bath."

On a big living room, the group were waiting for the Fire Lord to appear, once he did that, all of the group stood up, like covering something

"Oh, hello, What's up?"

With confident smiles on their faces, they showed an enormous cake from their hands

"Happy 19th birthday Zuko!"

"Waaaahhhh!" he completely forgot about that due to his training "Oh, it's true, jaja."

"That's strange, everyone on the city looks really happy and preparing an enormous festival, how did you forgot something like your birthday?" Suki asked

"Training."

Everyone sighed, then Sokka replied "You concentrate too much on training those days, if you let me say that."

"Is ok, fortunately I can rest now, my training finally gave me the results that I wanted"

"And that is…" Toph asked

"My most powerful technique ever, the Fire Cannon" the Fire Lord said

"Sounds cool, can you show it?"

To Aang request, Zuko denied it "Not here, I could end up destroying part of the castle"

"That sounds like a technique I would like to see… if able of course."

Again, Toph taking advantage to joke about her blindness that made everyone laugh

Zuko asked again "Who made the cake?"

"Both me and Katara" Suki said

"Hopefully you like it, it is our gift for you" Katara put the cake on a table near them

Aang then approached to Zuko -I went to the Air nomads Northern temple in order to find something you like- and he gave him a collar

"If it comes from your nation, it means a lot, thank you" and put it himself on the neck, then he looked to Sokka and Toph

The water tribe warrior felt guilty "Sorry, I wanted to buy it here."

"Me either" Toph said while raising one of her hands

"It doesn't matter, I'm not angry for that" Zuko said, then realizing something "Well, actually you can help me with something, that can count as my birthday present."

"Sounds like a little adventure" Toph jumped a little, producing a micro quake on the castle

Once it stopped, Zuko explained "Well, I suppose that later today a festival will be made to celebrate my birthday so, you can help a group of collectors to go for some fruits in order to make some food, will that be okay for you?"

While Sokka just raised his shoulders, Toph sighed "That was not the adventure I had in mind."

"Oh, come on, maybe you can find something fun to do there" Katara said

"Yes, here we have to help doing the preparations for the big party, so you will have an easy part" Aang added

Toph just sighed again and moments later she was there alongside Sokka who was acting like a leader for the collectors

"This is boring, I should have stayed on my metal bending school but you had to convince me to come Sokka."

"Come on Toph, sometimes you need to go out and have some fun, Don't you think?"

"No."

That gave an awkward silence to the duo

"For me, fighting and teaching is fun, you see, I'm not that used to parties, even after finishing the war."

"I know, but think about it, after so much peace, if a new danger comes, all the four nations will be joining forces to take it down, it has already happened before, no one was able to take the Team Avatar down since the war."

"Yeah, it has a positive side."

Again silence, until one of the collectors advised the group "We arrived."

A forest with a lot of bushes that were "Decorated" with purple dots was noticed, Sokka rapidly approached to one

"Blue Grapes bushes, their fruits are so delicious" took two and ate one "Here, take one Toph."

Again, he forgot a crucial thing, as Toph received it directly on the face "Idiot."

"Yeah…"

While on the palace, Zuko and Suki were chatting, leaving Aang and Katara to spend some time alone, the Fire Lord was talking

"It was pretty lonely since you and the Kyoshi warriors returned to your land, are things better now?" he asked

"Yes, the town became bigger and the group also."

"Wait, if you're here, who is in charge now?"

"Ty Lee."

That made Zuko to stop for some seconds "Hopefully things are not turned into chaos there."

"Well, she showed a lot of skill and compromise for being on the group, so it was her time to show leadership skills, it will be fine… I hope."

….

Needless to say, that the Kyoshi headquarters were not on the best conditions now, not destroyed, but totally dirty, apparently certain someone had the idea for a new weapon and it exploded, making almost everything on the insides dirty with mud, the Kyoshi warriors knew who the guilty is

"Suki… why?" and Ty Lee was totally ashamed

"And how are things going with Sokka?"

"Totally fine, we had some troubles after not seeing each other for so long, but I think we will manage our relationship."

"I hope that you two can become happy in the future."

Noticing his sad face, Suki asked "Still with problems after what happened with Mai, right?"

"How did you…"

"I'm a girl, we have that 6th sense."

It was hard to admit, but not as much as before "Hate to say that but yes, it was her decision and I have to respect it, but still…"

They decided to return to the living room, just to put a pair of epic poker faces after watching both Aand and Katara being really lovely with each other, even if they were just kissing, because of the surprise both separated from what they were doing.

"It reminded me of that day on Sokka's tent" what made Suki to take some steps aside of the fire lord, while he was smacking his face

"Sorry Zuko, as we were alone well…- Katara was trying to explain but to no avail"

"It was not a nice thing to do" Said Aang

While still hiding his face with his hand, Zuko answered "At the right on the bottom, there is an empty bedroom."

On the mission of collecting the berries, while Sokka had no problems on filling his wood chest, Toph was another story, due to her condition she had to find one via touching to put it on the chest, still, some berries were falling to the ground

"Sure, a good idea to send the blind girl to this kind of missions, and Sokka isn't even helping me" speaking about him he approached and started to help "Oh, thank you."

"Sorry, I got a little carried with this."

"It's ok, maybe on the party we can have some fun."

"Well, speaking about that…"

"I know, you want to have some time alone with Suki."

"How did you know that?"

"Don't remind me of the worst night of my life during the war, hopefully you had some protection while doing it."

Sokka just laughed with some shame, knowing which day she was talking about, even Zuko was traumatized on that moment

"Hehe sorry" but still he noticed that Toph was pretty sad "Ok, here is the deal, once we are on the party, I promise to dance with you, is that a deal?"

The blind bandit smiled a little "Sounds nice."

It was on that very moment that the entire group heard a massive sound, an explosion came from behind them but not hurting anyone

"What was that?!" Sokka asked

"Finally, some fun after just collecting stupid berries, come on Sokka!" the earth bender jumped happily before running towards the direction of the explosion

"Wa… Wait Toph, it can be dangerous!" Sokka was forced to follow her

"I was born to face the danger Sokka!" as stubborn as always

He just sighed, and said something to the collectors "Go back to the city, maybe you will want to stay safe."

The group did exactly that, while the warrior followed Toph as fast as he could, the bandit stopped near to the smoke so Sokka was able to chase her, once with her, he decided to look whatever it was there, his comrade asked

"What is that?"

"Well…" Sokka looked at it, black, metallic, with a red visor, very sinister "It…is like a metallic statue, a really odd one, I've never seen something like that before"

He approached to the "statue" looking it with a lot of curiosity, touching it, smelling it

"It looks like a new style of art, really modern if you ask me."

Toph decided to approach to it, but stopped, something was wrong and she was able to feel it on the ground "Heart beats?" and said it to Sokka "Come here now Sokka."

"What, Is something wrong?" he obeyed the suggestion

"Kind of, it is better if you come back here."

"But, why?"

His question was answered as from one arm of the "statue" an electric whip appeared

"Because that thing is alive!"

The whip was launched to the pair that barely avoided the attack, Sokka was afraid as he came without any weapon to defend himself, on the other hand, once the "Statue" moved in front of her, she smiled

"Finally, a good challenge after so much bullshit!" with hand poses she summoned to rocks from the ground, launching them to her opponent who just destroyed them with a whip slash "Cool, I can sense that you are gonna be such a challenge."

Another whip appeared on the other hand and tried to land an attack on Toph, who just jumped on its back using her earth bending as a trampoline, once on the position, she raised a leg to bend the earth in a way that made the creature to jump against its will, but landed pretty fine, from one of its shoulder 3 little electric balls were launched, at the same time as Toph was launching an earth wall, the impact produced a little explosion

"Way to go Toph, kick that monster's ass!"

The blind bandit was paying attention to whoever was coming, trying to cope with the attacker lightning attacks

"I know where you're coming, and it won't work" 3 more light balls came from her but her bending abilities made Toph to go some centimeters down on the ground, avoiding the attack "My foot and ears are my eyes, you have nowhere to attack me."

Once the rubbish was gone, the metallic creature started to think

"She is tougher than I thought… however the other guy..."

And put full attention to Sokka, deciding to attack him with a whip slash, even yelling, Sokka barely avoided the attack

"Hey statue, your battle is with me!" Toph yelled really angry

It was so strong that cut a tree behind him, looking at that, the warrior touched his neck

-My head was so fortunate- but he was not aware enough that another whip attack was coming to him

-Move idiot!

On that very moment, Toph was able to jump towards him with enough speed to launch both of them to another side, missing the attack by maybe millimeters

After falling to the ground, Sokka sighed "Phew, thank you Toph."

"Aaaaaaaahhhhhh, my eyes!"

Millimeters, not enough to cut anything, but enough to hurt with the light, Sokka was totally surprised for that

"Your eyes? But you're blind, you can still fight!"

"Stupid, it still hurts a lot!"

"No need for bad words."

The machine then approached to the duo "You were fortunate that your friend saved you."

Making Sokka shiver in fear "You can talk?"

"Wait until I put my hands on you, little piece of crap… dammit, my eyes!" Toph was still dealing with the pain

"But you won't have that luck again."

Being defenseless against the upcoming attack, Sokka just closed his eyes but thankfully, help came, some of the collectors were fire benders, and launched the attack towards the metallic creature

"Run, help you friend and communicate this to the Fire Lord!" said one of the collectors

Sokka helped Toph to stand up "What about all of you?!"

"Just run!"

Sokka had to obey if he wanted to survive alongside a really hurt Toph who was still sobbing due to the pain in her eyes.

The door of the palace was opened with a really tired Sokka, who was gasping a lot due to his effort, while his comrade was crying in pain

"Katara, where are you?!"

Zuko and Suki came to aid "What happened?" asked the Fire lord

"A metallic creature with thunder whips attacked us, it almost killed Toph!"

"My eyes, it hurts a lot!" she said

After hearing all of that, both Katara and Aang went to the rescue "Oh no, Toph!" she approached to her "I need a bowl of water as soon as possible!"

Zuko then said "Whatever that thing is, we need to investigate, Sokka, guide both Aang and me to the place of the attack."

He nodded "Sure" but once Aang approached to him "By the way, what were you doing with my sister?" making the air bender to giggle

Moments later and being helped by Appa, the trio approached to the explosion place, Sokka showed it

"How in the world can something like this happen?" Zuko asked

"I don't know, it was just there" Sokka said "It went all berserk and just attacked us."

"I see, by the way, what happened with the collectors?"

Being as horrorized as he was after looking the corpse of his friend, monk Gyatso on the air temple, Aang was looking towards the forest

"I know where they are" Looking at the same direction, the other two were feeling really sick "And whatever or whoever that creature is, for sure is a monster."

As that they noticed the corpses of the fighters, no more than 4 who perished with cuts on their bodies, the three will immediately knew it, a new threat has just come
