A Ninja in The Stone Age

by Chillman22

One-Shot. He had no idea where he was, all he remembered was escaping and finding himself somewhere else, though luckily a kind man took him in, though he became a fan of Legolas, even if his adopted brother was too logical to like it himself, but he'll prove him wrong, some how, but he had no idea that everyone would be turned to stone even himself, what could Naruto do. Adoption.

I know the title is a little confusing, but I'm sure that once you begin reading this one-shot idea, you'll be 10,000,000,000% excited. lol

Also it's up for adoption, along with my other stories and one-shot, minus The Brother Of Hercules, though I'm a little scatterbrained about that story mostly because of the C-Virus(Coronavirus), also I'm gonna have a break from writing until some of my ideas get adopted, hopefully a few people'll be interested in doing so.

A Ninja in The Stone Age

Chapter 1

Pilot

Unknown Alleyway

He didn't know where he was, at first he thought he was in an alley in one of Konoha's main streets but it turns out he was somewhere else all together, he was shivering under a ragged blanket feeling cold and hungry, that is until.

"Hey kid, what're you doing out here alone!?"

A voice called out to him, slowly looking up he saw a middle aged man, his hair just above the nape of his neck and has a buzz-cut beard and mustache. His hair is blond and he has brown eyes.

The now young child, with spiky blond hair and deep blue eyes, with whisker-like birthmarks on his cheeks, looked towards the middle aged man, who was smiling a kind smile at the lad, "I-I don't k-know w-w-where I am!" The child looking no older than 9 years old, though with a malnourished body it was almost difficult to tell.

Hearing the answer, the man replied, "Well, how about I look after you until we find your folks huh!?"

This caused the child to start crying, since he never knew true kindness in his life, the middle aged man held his hand out wanting the boy to take in order to help him, "My name's Ishigami, by the way, Ishigami Byakuya!" He tells the lad with a bright smile.

This in turn caused the child to smile as well, "I-I'm Uzumaki Naruto, nice to meet you old man!"

As soon as Byakuya heard the "old man" comment, it caused him to stumble slightly, then looks towards Naruto with a strained smile, "I'm sure my son, Senku will get along with you just fine."

One Year Later

After that chance meeting, with Naruto having nowhere to go, Byakuya had decided to adopt Naruto, though Naruto wanted to keep his last name, Byakuya figured the best idea was to turn it into a middle name for Naruto, making his name, Naruto Uzumaki Ishigami, which Naruto was alright with.

Though when the 15 year old Senku at the time first met Naruto, he could understand the logic of Naruto staying with them, but he never really planned for an adopted little brother, but as much as he tried to deny it, saying how troublesome having a little brother would be, though as soon as he saw Naruto's teary eyes, he just looked away and grumbles that it might not be too troublesome, causing Naruto to brighten up and tackle his new big brother, along with making Byakuya smile.

During the year together, Naruto's body was no longer malnourished, now it was the right amount for a kid his age, but he was still hyperactive, where the only time he calmed down was watching movies for "family night", but unfortunately for Senku, Naruto's favourite movies were The Lord Of The Rings and The Hobbit sagas, though more than likely, he was in awe of the elf-archer known as Legolas, Naruto just couldn't help but be amazed at the elf's agility, speed and skills, he especially enjoyed the part where Legolas defeated one of those elephant-like animals (he's 9 he can't pronounce Mumakil yet), where the dwarf exclaims, "THAT STILL COUNTS AS ONE!"

Though during that scene even Senku and Byakuya laughed with Naruto, though you probably wondering how Naruto got his science-enthusiastic brother to watch a fantasy movie together, well he used the ultimate technique that no-one could say no to, his big blue innocent eyes that his brother practically caves-in, while saying out loud, "This is 10 billion percent too troublesome." Causing Naruto to smile that he got his brother to watch such a thing, though that doesn't stop Senku from poking holes in the fantasy, which in turn causes the 9 year old Naruto to pout yelling that it's not the point as long as it's fun to watch.

Also during that year, Naruto ended up meeting Senku's other friends, one called Oki Taiju, or as his big brother calls him "Big Oaf!" But Naruto knows there's no malice behind it, though after hearing Taiju's loud yelling, Naruto could understand slightly why Senku calls Taiju that, since it's obvious that the lovable oaf just doesn't know how to control himself when he gets excited.

Then he met Ogawa Yuzuriha, who that Naruto was super cute, causing young Naruto to blush and poke his fingers in embarrassment, causing Yuzuriha to uncontrollably hug Naruto nearly to death, causing Taiju to cry "manly" tears in jealousy, though Senku told the boy that Naruto was only a kid, there's really no point in getting jealous.

Unfortunately for Naruto, Yuzuriha ended up teaching Naruto everything she knows about arts and crafts, since he was just too cute to her that she couldn't help but to dress him in some of the outfits she made, even explaining to him how to properly make clothes and shoes, among other accessories, along with the history of clothe-making, causing Naruto untold amount of embarrassments and having steam coming out of his ears from information-overload, but it still stayed in his head since he didn't want to upset his "big sister" at forgetting her lessons.

But now, Naruto was just happily enjoying his new life, going to school, hanging out with his brother and his friends, though he'll miss Byakuya since he'll be in space for a while, though he was happy that his adopted father was living his dream of being an astronaut.

That is until.

"VRRRRRROOOOOOOOOOOOOOOOOOOOOOOOOOOOOMMMMMMMMM!"

Standing next to a tree, Naruto witnessed a strange sight, a bright green light was engulfing everything, he couldn't understand what it was, but before he could even think to try and run, his body was also engulfed in it as well, turning him to stone, with the last thought he had was, "Senku nii-chan! Help!"

Then everything was at a standstill, every human being was turned to stone.

3700+ years later

3 Years Before Senku is free

The world had shifted, turning back to it's natural ecosystem, only difference is, the naked stone statues laying around, with some having moss covering them or were unfortunately broken apart due to the growth and shifting lands, but by an overgrown tree, where a statue of a 10 year old Naruto was safely nestled in the tree growth, almost like the tree was protecting him.

That is until, "Crack! Crack!"

His stone shell was slowly breaking, but not only that red glowing lines were making the cracks, before long Naruto's stone skin had busted and young 10 year old Naruto was finally free of his stone prison, slowly blinking his eyes, Naruto's vision came back into focus, "W-What, W-w-here am I, huh!?"

Looking at where he was, Naruto noticed he was being held by a tree, "Huh, you protected me didn't you!?" Getting no answer but a gentle gust of wind, Naruto looks around, wondering where he was and what on earth happened to everything.

But at the moment he knows he has to focus on other things, being thankful that Byakuya allowed him to join the scouts for a few months, though that's mostly because of Naruto's hyperactivity, so the scouts were perfect to get Naruto to focus on how to survive in the wild.

At first Naruto wanted to cry at his misfortune, losing his only family and friends, that is until, (SLAP!) he slaps both his cheeks, "NO! That's not what they would've wanted, I can't keep crying, I need to stay alive, that's what they would've wanted!"

So starts Naruto's journey to surviving in this new unknown world that he finds himself in, not only wanting to survive but to hopefully see his brother and friends again.

6 Years Later

On the ground were a family of boars, each one sniffing and trying to find food, though somewhere high in the trees a figure was hiding, jumping from branch to branch with his hair whipping through the wind, but what was strange was he didn't make a sound, he was tall and lean showing that the life he was living made him strong and fast, but mostly fast, his eyes narrowed at the sight of his prey, staying around this part of the area hoping someone will escape their own stone prison, but right now he was focused on something far more important.

In one of his hands was an iron bow, fashioned with leaf-like emblems and other wood-like vines, quietly he pulled an arrow from his quiver, showing an iron tip at the end of it, while sending a silent prayer to his friend teaching him arts and crafts, since the lessons also taught him how to make the clothes he was wearing. (A.N. I'm not describing since it's basically modelled after Legolas.)

Slowly and quietly, he drew back the bow, taking slow breaths until.

"SSSSSQQQQQQQQQQQUUUUUUUUUAAAAAAAAALLLLLLLLLL!"

His aim was true, he managed to hit his target with a killing blow, which in turn caused the other boars to runaway, scared for their own lives.

Making his way to the recently killed animal, he sent a silent prayer for the creature, but he needed the meat for food and the flesh for leather, so tying the boars front and back legs together along with wrapping a tarp around it so the blood doesn't leave a trail, the teen lifted the heavy boar with ease, climbing and leaping from tree to tree back to his hideout, high in the trees, away from large predators.

He then started the arduous task of skinning, gutting and cleaning the boar, not wasting a single stroke of his knife-work, all the while putting the guts in a clay pot for disposal at another location, with the prep-work out the way, he went about cooking to meat, making sure to cook it all so it wouldn't get spoiled, once that was done, he stored the meat away, while eating some of it now, while at the same time drinking some fresh squeezed fruit that he had in a cup for himself.

"RRRRRRRRRRRRRROOOOOOOOOOOOOOOOOOOAAAAAAAAAAAAAGGGGGGGGGGGGGGGHHHHHHHHHHHHHHHHHHHHHHH!"

""AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAARRRRRRRRRRRRRRRRRRRRRRGGGGGGGGGGGGGGGGGGGGHHHHHHHHHHHHHHHH!""

That is until he picked up a loud roar of a lion and a pair of screams that he hadn't heard in a long time, well, for 3 years to him, since he doesn't know the date, quickly rushing outside, grabbing his bow, arrows and daggers, along with a hooded shawl, covering his weapons and head with it, he began jumping and swinging from branch to branch, his heart racing a mile a minute, hoping beyond hope that his mind wasn't playing tricks on him.

He soon came upon a sight that took his breath away, there were three people below him, with two of them being familiar faces, though the tall muscular teen stroking the dead lion made the stranger in the tree nervous, but for now he was too focused on the other two teens.

Leaping from the branch he was on he landed in front of the two teens he was focused on, but what surprised the two was he didn't make a sound when he landed, that is until he began talking, "I must say, it's been far too long Senku nii-chan!" His voice was slightly gravelly and deep, as though he hadn't talked for a while.

Tsukasa was about to punch the mysterious person that appeared before them, but stopped when he heard what the stranger called Senku, though the ones who were truly shocked were Taiju and Senku, but as Senku took a closer look at the stranger, he noticed the outfit he was wearing, "W-Wait, that outfit, I know I've seen it somewhere before!?"

Before anything else, the stranger quickly drew an arrow and fired, just past Senku's head, but what shocked them was that the speed was unbelievable, he withdrew an arrow in nanoseconds, but what really shocked them was that behind Senku was a snake with an arrow piercing it's skull through it's open mouth, showing that it was about to bite Senku, but also showing that the stranger had saved him.

The stranger smiled, "Do you think that Legolas's skills and abilities are still illogical now Onii-chan~"

Hearing that name, Senku's eyes widen, slowly he turned his head just in time to see the tall stranger pulling his hood down showing long golden blond hair that flutters in the wind, with narrowed blue eyes, but what caught both boy's attention were the whisker-like birthmarks on his cheeks and a smirk on his face.

"WWWWWWWWWWWWWHHHHHHHHHHHHHHOOOOOOOOOOOOOOOOOOOAAAAAAAAAAAAAAAAAAAAAAAAAAAA!"

"N-N-Naruto-kun!? Is that really you!?"

The now older Naruto smiled with some light water in his eyes, "Hello Senku nii-chan, I see Taiju nii-chan is still as loud as ever, welcome back."

Senku couldn't keep the smile off his face, "Yeah "little" brother, I'm back."

Tsukasa was smiling slightly at the strange reunion the apparent brothers were having, he was also pleased that they weren't the only humans around, but from what he could gather, this "Naruto" person had awakened long before the other two teens, yet he couldn't help but wonder how that happened without the formula that Senku gave to himself, but he suppose there really isn't a point to such a question.

Senku and Taiju were happily patting and slapping Naruto on his shoulder and back, though Taiju's strength didn't seem to effect Naruto much, showing just how strong he became on his own, "So Naruto-kun, how old are you now!?" Taiju couldn't help but ask, with Senku slapping his forehead, "That's completely besides the point you Oaf!"

This scene was causing Naruto to laugh, he couldn't help it, he always enjoyed hanging out with Senku and his two friends, with Taiju doing something as funny as this, finally managing to get his breath back, Naruto replied, "Well from what I understand, it snowed six times since I managed to escape my stone prison, so I think..." Trying to count on his fingers.

That is until, "You're now 16 years old Naruto-kun, my god, you've been on your own for over 6 years." Senku couldn't believe that Naruto managed to survive for so long by himself.

Hearing this, Naruto was wide-eyed, "Has it really been that long, I couldn't really tell, all I did was mark down each time the weather became so cold that it snowed, I was just happy that Yuzuriha nee-chan's lessons helped me stay warm and safe, along with the few months in the scouts helping here and there, not to mention my experience by myself allowed me to pass the time by making my iron bow, arrow tips and iron daggers."

Putting his bow on his back, Naruto took his daggers out to show them to his friends and brother, with Senku exclaiming, "My god, you really have been by yourself for a long time, by the looks of things it must have taken you just under 5 years to make both the bow and daggers separately! Wait! D-Did you model your stuff after Legolas's equipment!?"

Naruto puts his things away, then rubs the back of his neck nervously, "Well I was a big fan of his Senku nii-chan, I figured he was the perfect role model to mould myself after, also I wanted to prove you wrong in saying how illogical it was for someone to have such skills!" He tells them with a big smile.

With the three sweatdropping, while thinking, """He did it JUST to prove Senku was wrong!"

Here Senku began laughing, "You're right Naruto-kun, you were 10 billion percent right, you have, for the first time, proven me wrong!"

With both brothers and friend laughing together for the first time in over 3700+years, even Tsukasa smiled at such an odd thing, but he couldn't deny the bright atmosphere he could feel the three had.

With Naruto noticing a familiar leaning against the tree, "Is that Yuzuriha nee-chan!?" Making both brother and friend look towards the girl with happy smiles.

Though they soon noticed the frowning face on Naruto's, but suddenly, "Relax Naruto, Senku had figured out how to get people out of their stones!" Taiju exclaims while wrapping an arm over Naruto's shoulder, though it was slightly difficult and Naruto had to bend down slightly, showing he was taller than Taiju, which the "big oaf" noticed, "WWWWWWWWWHHHHHHHHHHHHHHOOOOOOOOOOOAAAAAAAAAA! YOUNG NARUTO IS SOO~ MUCH TALLER THAN ME NOW!" He couldn't help but cry jealous "manly" tears.

Causing Naruto to flinch back a bit since his ears were now sensitive after spending so long by himself, hearing Taiju's yell while nostalgic gave his ears too much pain, though as he straightens up, Tsukasa was standing next to him, allowing Taiju to compare both teens, "WWWWWWWHHHHHHHHHHHHOOOOOOOOOOOOAAAAAAAAA! NARUTO-KUN AND TSUKASA-SAN ARE PRACTICALLY THE SAME HEIGHT I'M SOO JEALOUS!"

"WHACK!"

"Would you calm down you big oaf! We need to get back to camp and free Yuzuriha-san right! So let's go!"

As it turned out Senku had smacked Taiju upside the head, causing the teen to stop yelling and quickly rushed to the stone girl, they were about to head off, but Naruto was not following, "You guys go ahead, I need to pick up a few things from my own camp."

Before any of them could say anything, Naruto shooting up a tree as quick as a flash, vanishing and not making a sound at all, with Senku cracking his neck slightly, "Now that is both cool and gonna be super annoying, I can 10 billion percent guarantee it."

The End.

There you have it a Naruto/Dr Stone Crossover one-shot, with a slight LOTR mixed in, since I figured Legolas's abilities and skills would be perfect for Naruto in this type of crossover, also I figured Yuzuriha would have a hand in teaching Naruto her artisan skills as well, since she'd get carried away.

Also as for the pairing, I was thinking, a Naruto/Kohaku pairing, with a few of the village girls thinking that he looks super handsome, or something, but nothing happening since Kohaku would find Naruto attractive.

I can also see Naruto showing Senku up slightly by just easily lifting the log on top of Kohaku with ease, while telling his brother that he did spend 6 years by himself, there was no way he'd stay a weakling.

Also I'd like to point out that it's obvious that Naruto would be a little OC, since he's in a different world trying to figure things out he's bound to become an OC.

I forgot to mention, during the whole "killing Senku" thing, I can see Naruto going off on a hunting run to get some food for everyone, then when he returns he see's Senku just "waking up" and tells them that he and Naruto will go off on their own, while Yuzuriha and Taiju keep an eye on Tsukasa.

I Do Not Own Naruto Or Dr. Stone. Or LOTR.)
