Chapter 1: Prologue

Naruto 100 crossover

I don't own naruto, 100 or any of its charcters.

Prologue

AN: to those who've already read my story before, I put the 4 chapter I already published into this single one, to get a better structure, also I'll most likely rework this chapter someday since my writing style has changed and there were a few flaws in it.

Void. Empty space that's all Naruto recognised while floating in space.

Now you may ask why Naruto is floating in space. Well the reason for him floating in space is what happend a few minutes ago. Naruto and the Shinobi Alliance won the 4th great Ninja War with the help of the bijuus and Sasuke. Though after Kagura had been defeated by Naruto and Sasuke, Sasuke turned on the Alliance and the whole Elemental Nations. He wanted to rule over it and for that he trapped the Bijuus before challening Naruto to what he assumed would be their last duel.

Naruto, wanting to protect the Elemental Nations accepted the challenge and the fight for freedom of Humankind began. They battled for 2 days straight matching blow by blow. But while they grew tired and weaker the bijuus grew stronger. When they noticed their stone imprisonment getting weaker and starting to crack they took their chance to break free.

Now while they were less agressive than one would picture Bijuu to be because of Sasukes betrayal they were furious and lost all hope in humankind other than in the child of prophecy Naruto. So in an attempt to save themselves from getting used again they abandoned their physical forms and tranformed into energy which headed straight for Naruto. Which had disasterous effects because at the same time they were absorbed into Naruto he was in a power struggle with Sasuke, Chidori against Rasengan.

Now because of Narutos increase of power the air seemed to start to crack, when the cracks grew to a considerable size a hole formed in the middle which sucked Naruto in while dematerializing Sasuke. This would be the last day Naruto existed in the Elemental Nations.

And now we find him in an alternate universe slowly suffocating in space. Shortly after he appeared in this universe he fell unconscious from the lack of air, he didn't have to worry about freezing to death as the bijuu were giving him enough chakra to keep their host from dying. This caused the 9 bijuu to fall into a deep sleep which would last for god knows how long.

While Naruto was drifting in space some people from this universe observed him and were surprised because they saw him appear in a bright flash. These people were located in the observation room of the arc also used as command center.

The appearance of Naruto caused a great panic at first, though chancellor Jaha quickly calmed the people down in order to determinate the situation. The chancellor presented the 2 choices they had. First they could ignore whoever it is that's drifting out there and carry on with their plans to send the 100 prisoners down to earth in a few days' time or they could investigate the appearance of this unknown person. Most of the council voted for Jaha to decide what he thinks is best while the police chief expressed his concerns about letting an unknown possibly dangerous person or alien enter the arc dead or not.

Jaha asked for the opinion of the arcs doctor and she told him that there is great promise in salvaging the person for example they may be able to find out how he suddenly appeared and use this technology for themselves. Jaha agreed and orderd for one of the mechanics to go out in a suit and bring him onto the space station.

After Naruto was brought on board he was checked for dangerous substances and then brought to the arcs medic bay to determine if he's human. All the while they failed to notice the almost none existing pulse of Naruto slowly increasing. Abby got a huge scare when she examined him, was about to cut him open to do an autopsy and he suddenly started breathing. She immediately checked his overall health and send a helper to fetch Jaha and Marcus asap. A few minutes later she told them the situation Naruto is in, which was that he is unconscious and suffered various wounds which were rapidly starting to heal she also told them that he has similar genetics to humans but is definitely not entirely human she assumed him to be a mutation which could explain his rapid healing.

Jaha decided to bring Naruto into a prison cell transformed into a secured patient room until he wakes up and they can question and further investigate him.

Chapter 2: Before the launch

The next morning Naruto awoke with a jerk "whoa I dreamt I was suffocating in space. He looked around the room he was in, it was a very small room with only a bed and a toilet. "Huh weird I could have sworn I was fighting Sasuke and won, guess someone picked me up and brought me to a hospital, looks weird but beggars can't be choosers."

Suddenly he heard an intercom say "this is Chancellor Jaha I was made aware that you regained consciousness. We welcome you on the Arc but have to question you to ensure the safety of our people."

"Huh Arc what`s that, I guess this isn't a hospital afterwards" Naruto murmured to himself, then replied "Ok that's understandable, I got some questions of my own too though."

"I will try to answer them to the best of my abilities when I'll see you in a bit" Jaha replied over the intercom and then made his way over to the prison cells.

On the way Markus joined him on the way to the prison cells "Chancellor I advise you from speaking with the refugee alone you can't be sure if he`s dangerous or not, we checked for weapons and only found some old style knifes which implies that he might be some kind of warrior."

"I understand your concern Markus but if we want to get valid information from him we need to show him that we trust him to some degree" Jaha replied.

They arrived at Naruto's prison cell "Open the door please."

Jaha entered the Cell and observed the Teenager of unknown origin.

"As I already told you my name is Jaha, may I know your name?"

"Naruto Uzumaki, at your service" Naruto told him smiling. "So you said something about questioning me and an arc, what was that about?"

"Straight to the point , I like that" Jaha answered "Well to clarify we are currently in the prison department of the Arc an Space Station we lived on for 97 years ever since our former governments made the Earth uninhabitable with a nuclear war. And I want to get to know you a bit better before I make my decision on whether to release you or keep you in the Cell for the time being."

"Space station, Nuclear war, I can only imagine what that means where I come from we didn't have much on the Technology department. So I'm guessing you don't know where the Elemental Nations are and if there are any shinobi still around? That's what the continent where i come from was called." Naruto asked with hopeful expression on his face.

"No I'm sorry to say that I never heard of it, neither do I know what a shinobi is, but I am surprised that you claim that your people aren't technological advanced, I along with the rest of our government saw you appear in space out of nowhere and we salvaged you."

"Hmm, that's weird the last thing I remember is fighting my former teammate after he turned on our people. And Shinobi are Ninjas or something like soldiers. But I guess my dream of floating wasn't a dream after all then. And I thank you very much for saving my life from suffocating in space." Naruto replied with a slight bow.

"So you don't know how it was you appeared in space?" Jaha asked with a bit confusion showing in his voice.

"Well no not really but I have a guess, something must have happened during the fight I told you about which interfered with my jutsu, maybe I can use the technique of the Person who tried to enslave our world, you see she was able to travel to different dimensions." Naruto said hoping Jaha could follow his trail of thought.

"Jutsu what`s that? Also would you be ok with being medically examined because that someone of your race could travel through dimensions sounds very interesting." Jaha asked hoping that they could replicate this ability so they have other options on how to increase the oxygen on the arc.

"Well I'm ok with being examined but I may not be very useful for you because I'm not sure if the person who used dimension travel really was human, because her origin still is a bit weird to me. Also jutsu are techniques you use by transforming the chakra that is in every living being." Naruto explained.

"I appreciate your cooperation and will send our chief of medicine to see you, maybe you can explain this chakra to her, because I have never heard of it." Jaha thanked Naruto and made his way out of the Cell.

Jaha send some people to fetch Abby Griffin so that she could take a look at Naruto also hoping she would understand his explanation on their techniques. He then went on to inform the council members about the information Naruto provided

After Jaha briefed the council

"Well this is the explanation Naruto provided on his appearance and I would say that while very interesting it shows little promise to our problem on fixing the Oxygen shortage on the Arc if he doesn't know how he appeared here. So let's vote on 2 things first, shall we continue the launch of the 100 prisoners as planned?" Jaha asked the council members.

Almost all of the council members voted for sending the prisoners down to earth with only one disagreeing probably because his son was one of the ones who would be send down.

"Ok I guess that's handled and I will inform Abby to prepare the launch in 2 days. The next thing we have to vote is what to do with Naruto. I see 3 options, first we float him because he could become dangerous, second we keep him on the Arc to study him, though this is depending on what Abby can tell me after the examination. And the last option is to send him down to the ground with the others, he seemed to be a good hearted person from what I could tell and might be beneficial to the 100 since he claimed to be a warrior of some kind."

There was a long pause and the council shared their opinions amongst each other. They voted for Naruto to accompany the rest to earth if Abby is of the opinion that He doesn't hold any value to them in regards of fixing the arc.

Meanwhile Naruto got examined by a woman called Abby who seemed like a kindhearted person and also very loyal. She took a few blood samples and other standard checkup tests and talked for about half of the conversation she had with him about her daughter Clarke. She then took her leave and told him that she may be back tomorrow if she is correct in her assumption that Jaha will include him in their project.

Naruto decided to see what these people will decide for him before he rouses suspicion or worse fear by checking what his capabilities were at the moment so he did the only thing which seemed logical to him, he tried to enter his mindscape in order to see if Kurama was ok or even still around. But he soon found that he couldn't enter his mindscape and then went to sleep till someone needed something from him, hey fighting 2 days straight and then getting flung into another dimension is tiring even for an Uzumaki Jinchuuriki.

Chapter 3: Before the launch 2

The next day

Abby walks through the arc on her way to the council chamber she carries a medical chart in her hand and glances at it with an curious impression every few minutes. The reason for her interest in the medical chart is, that these are the results from naruto's examination. According to the results of the test there is no difference between Narutos species and theirs, though during yesterday's short medical checkup she noticed that his muscles seem to be able to produce about 6 times the strength a normal person could. Abby without realizing it already reached the council chamber. She knocks twice and then enters, she was immediately greeted by the council and offered to take a seat. Abby took them up on the offer, sits down and passes the medical chart around so that the council can take a look at the results of the examination.

"So what do you say about our young dimension traveling friend Abby?" Jaha asked

"Well his bloodwork and other medical test show that there is no difference between our species but during the examination I noticed that his muscles were about six times as potent as ours which showes that there are some deviations between us." Abby explained

"Ok and what did he tell you about this chakra?" asked Jaha hoping it could be used to generate oxygen or has a similar use.

"Well from what could tell he told me exactly the same you briefed me about before I examined him. And while many uses it doesn't seem to be of any real use to us considering most our lifestyle is based on technological advancements." Abby explained

"Ok you heard her report councilmembers do you all agree to our pre-determined course of action or does someone want to reconsider it?" Jaha questioned the councilmembers

Everyone shook their head negative then Jaha declared "Ok then we will proceed as planned, Abby how would you feel about talking to Naruto again?"

"What do you want me to talk to him about?" Abby asked already guessing the answer

"I want you to ask him if he wishes to join our expedition project and you should also explain our situation to him so he will be nudged to join in since there already is an oxygen shortage."

"Ok I will ask him" Abby says standing up intent on making her way to Naruto with some food to talk to him about the situation over breakfast.

15 Minutes later she arrives at Naruto's cell.

She knocked once, then entered "Hello we meet again Naruto." Abby said cheerfully "I brought you some breakfast."

Naruto already being awake for about 40 Minutes smiled and thanked her while accepting the tray.

"So Naruto as I already assumed during your examination yesterday in was send to inform you about our current situation and a project which will be launched tomorrow." Abby says hoping to catch Naruto's interest.

"Well to start off our situation on the Arc is rather bad, currently there is an oxygen shortage because of a system failure and its likely we won't be able to fix it in time."

"Oh that sounds bad is there anything I can do to help?" Naruto asks trying to repay the kindness they showed him so far.

"No sadly there is not but you can help us with the project if you are willing to do so. You see we are currently uncertain if the Earth is survivable and are sending our prisoners down to spare their life and give them a chance for a new beginning if everything goes well and the Earth or at least the place we are going to send them to is safe." Abby says hopefully

"Well sounds like an adventure and Naruto Uzumaki has and always will be all about adventure, so count me in." Naruto says smiling.

"That's great news but I want to inform you beforehand that while they are prisoners per se not all actually are bad people, they all are around your age and most only are in prison because the rules are very strict around here, because even a small mistake can have disastrous effects." Abby explained hoping this won't change his opinion of them.

"Even better, hopefully I can make some new friends" Naruto replies.

"Well that's good to hear Abby says smiling ,also I would like to ask you a small favor, you see my daughter will be one of the ones sent down and I would like you to look out for her since I imagine you will be able to protect her."

"Sure thing" Naruto replies, "Her name is Clarke right? You talked a lot about her during our first meeting."

"Yes that's correct and I appreciate your help. I will see you off tomorrow for the launch. Abby says leaving the room. Next she makes her way to report to Jaha and then hoping to get some shut eye."

The Next morning

Naruto awakes to see Abby standing in the doorway waiting for him to follow her. "I will escort you to the ship personally and will seat you next to my daughter so you will know who she is." Abby says.

Naruto thanks her for all she's done for him up till now and promises her to do his best to protect her daughter, hugs her good bye and then sits down like instructed by some guards.

Chapter 4: Launch & Landing

Naruto looks around and notices that he's one of the first people brought on board the dropship.

He thinks back on the information Abby provided him concerning the reason for sending them down.

Flashback

"Naruto as I already told you we are going to send you down hopefully near a military base called mount weather where supplies were stored before our ancestors left the earth.

In the dropship you will see a video of Jaha explaining this in more detail, I hope you will take our advice on going after those supplies asap. Also we are going to have everyone wear an armband which will let us monitor your vital signs to see if the earth is survivable.

That is all i can tell you concerning what we expect of you and the other 100 prisoners.

I hope this isn't too much to ask of you since you only came here a few days ago and dont know us very well."

"Nah, I can handle it , I'm not called most unpredictable shinobi for nothing." Naruto said grinning.

"That is some great spirit you got there." Abby said looking slightly surprised.

Flashback end

Naruto waited a good half hour before more and more teenagers got strapped down to the seats.

He notices many of the people looking at him curious and some asking him questions like "who are you", " how come Ive never seen you before? "

Naruto just shrugs the looks off and answers them by telling them the coverstory he and Jaha came up with the day after he decided to join the others on the dropship, which is that he says that he has been in solidary confinement for a rather long time.

When almost all seats were filled the seat next to him got filled by an unconscious Blonde who he assumed is Abbys daughter Clarke.

20 minutes later the engines start up and he notices Clarke wake up. She looks around surprised and then starts a discussion with a boy named Wells, who appearantly is the son of Jaha. Then like Abby said a video of Jaha started telling the teenagers what to do in order to increase their chance of survival.

He notices pretty much everyone was making a fool out of Jahas speech and summed it up to being angry for being imprisoned despite maybe not even being guilty of a serious crime.

About 5 minutes after the video stops the whole ship shakes like crazy and he assumes that they landed but as it turns out it was only the parachute opening after they entered earths atmosphere. 2 of the 3 idiots who were fooling around by floating without their securitybelt on lay on the floor with a broken neck, despite Clarke trying to warn them. Soon after they land he notices that many people didn't trust anyone other than their own little groups. Since the exit of the ship was on the lower deck Naruto stands up and makes his way to the ladder leading to the 1st floor.

Now we see him coming down the ladder to the bottom floor where everyone is gathering in order to open the door and see the outdoors.

"Hey lets open the door already whats the hold up" he hears some shout.

Naruto goes to the front of the room near the door inorder to see if there is some kind of problem. When he is standing infront of the door. Everyone shouts at him and the girl next to him demanding to know who they are and after its revealed that the Girl is named Octavia Blake most people laugh about her and make jokes about here living in the floor, somewhat confused he asks the girl if she's ok and she just blows him off saying, "leave me alone".

Shortly after that her brother Bellamy Blake shows up and makes everyone else back off since he's the oldest one on the ship and was trained as a guard.

Naruto is somewhat grateful that he doesn't get paid much attention since more people are busy with Ocatvia and her brother.

After hugging eachother Bellamy tells Octavia to ignore the comments and offers her the chance to be the first person to set foot on the ground.

He opens the door and ushers her out, when she exited the Ship she screams "We are back bitches!" After that

About 20 minutes after everyone left the ship and spread out on the clearing they landed on he sees Clarke examining a map looking for a good route to get to Mount Weather.

Naruto approaches her and says " Hey there need some help reading the map?"

"No thanks" she replies

"Hmm ok but if you need something feel free to ask, I'm a acquaintance of your mother and she asked me to look out for you."

"How do you know my mother ?" Clarke asked curious

"Well lets just say that she helped me out in a tricky situation." Naruto says trying not to blow his coverstory, since that would make people suspicious.

"Well if you say so but still, I dont need your help."

Their conversation gets disrupted by Wells and a kid named Murpy fighting because of Wells' father being the chancellor who inprisoned them and most others not wanting to leave the clearing for the supply run to Mount Weather with Clarke and Wells. During their little fight Wells falls down and twists his ankle.

At this point a kid named Finn steps in and makes Murphy back off.

Naruto was acctually hoping to see them fight because he's planning to seal off most of his chakra in order not to stick out like a sore thumb but he also needs to adjust his strength to some extend because according to Abby he has 6 times the power of the others.

While he was lost in thought Finn and Clarke grabbed 2 other kids inorder to get more people to go on the supply run. Octavia approaches them wanting to join in.

Her brother asks her not to go on off without him but she doesnt pay it much mind telling him that she wants to use her newfound freedom by making her own decisions.

Naruto snaps back to reality and tells them, "Well count me in im always one for explorig the unknown."

With that the group of 6 make their way to Mount Weather.

On the way there Naruto is distancing himself from the others conversation slightly, because he can't really tell them much about him without rousing suspicion. He learns that the asian looking guy is named Monty and his goggle wearing companion is Jasper, as he already learned before the others are Octavia, Clarke and Finn. As the little group is walkning through the woods , lead by Finn because he's the only one with tracking skills, other than Naruto of course , not that the others would know that most of them enijoy the nature and eachothers company. The only exceptions being Naruto and Clarke. As Finn tries to hit on Octavia by putting a flower in her hair Monty told Jasper that this flower is called poison Sumac. Octavia reacts by swatting the flower out of her hair before Monty even finished his sentence, explaining that it's a medicinal flower with a calming effect.

Jasper explained the group that Montys family was the ones handeling all the medical herbs on the Arc.

Soon after Clarke stops and wants the group to get focused on the task at hand : finding Mount Weather.

Finn remarks " Come on Clarke, how do you block all this out?"

" Because I'm wondering why we haven't seen any animals yet, maybe the air is filled with enough radiation to kill us , sure is pretty though" she replieswith a serious expression

As the group continued walking Finn inquires why Monty, Jasper and Naruto were imprisoned.

Monty explained that they were using some plants as drugs and Jasper cuts in and says while looking at Monty "and someone forgot to replace what we took".

Then Naruto answers Finn "I was caught stealing when I was young ,because I am an orphan I had no other way to get to food and such." meanwhile he thinks "at least I'm not really lying to them that happend to me just in Konoha not the Arc"

"So Octavia why were you locked up?" he asks trying to shift the focus off him

" Being born" She replied with a hateful expression on her face as she picked up speed in order to distance herself from them.

As the group continued on with the mood being not that great after Octavias reaction to the question, they saw a deer eating grass not far from them and crouched down in order to observe it , Naruto reminded himself that to them this is the first time in a forest and their first contact with animals.

As someone stepped on a twig the deer looked at them and they realised that there was a second head growing out of the first one.

" whoa what the fuck" everyone but Naruto screamed while a shiver runs down their spine. Naruto barely had any reaction because compared to some of the things he had seen in Orochimarus lairs that was nothing.

After calming down from their shock they continued on looking for Mount Weather.
