Author's Note

Hello Universe! Palkia is here once more with another story! (I have like a ton of these going on behind the scenes and I work on them when I get bored lol) Recently, I just finished Naruto Shippuden, and I love Kurama! He is definitely my favorite character in the entire series. I just wish they gave him more screen time in Boruto lol.

Anyway, I've been thinking about a crossover like this for a while, but I didn't know how to execute it, until the idea came to me last night. So i'm super excited to get this story going. Fyi, this is 2012 verse for the turtles, cause I love it to death. It'll mostly take place in the turtle universe, but maybe rarely check on the Naruto universe.

I'm gonna add in music for this. Oooo something new. Figured it would add to the mood. So here's how it's gonna go. You see this (1)? You play the song that corresponds with it. You see this (1!)? That's when you stop playing music. I won't say anymore, because I want surprises. Enjoy!

Here's the song list:

(1) Nine Tail Demon Fox- Naruto OST 1

(2) Beautiful Green Wild Beast- Naruto OST 3

(3) Sadness and Sorrow- Naruto OST 1

(4) Morning-Naruto OST 1

I'm probably gonna end up using a lot of Naruto and Naruto Shippuden OST. Just because the fic is part Naruto, and the OST is so good.

I do not own Naruto, and I do not own TMNT.


Prologue

Lone Fox and Cub

(1) Ah Konoha, the Village hidden in the Leaves, or to be specific, the Hidden Leaf Village. One of the most peaceful areas in all of the Land of Fire. And it was true. There was no fighting, no war, everyone was at peace. It certainly could not go bad anytime soon. Unfortunately for Minato, he knew differently.

The sight of a mountain sized, nine-tailed fox attacking the village showed him that.

Of all the days the darn thing had to be released, it had to be today. Course, he knew it wasn't his fault, or Kushina's fault. Someone attacked them when she was giving birth, and thus, the fox was set free and took his revenge on the village itself for sealing him away. Kushina had been giving birth to his son. He had hoped that something like this wouldn't happen, but as fate would have it, it did.

Finally, after finding his wife, the Hokage realized something. If the demon fox were to be sealed away again, it could not be in Kushina. From the looks of her, the strength from childbirth and the release of the demon fox had taken a huge toll on her. And unfortunately, she looked bad. And if it was sealed in her again, she would most definitely die. That was something that he didn't want to happen. Not after his son was just born. Minato did not want to think of Naruto growing up without his mother.

And even if she died, that thing would be revived again no matter what happened. And worse, it would have no host. More people could die from its rampage. As Hokage, he could not let that happen. Minato knew that some people in the village would have already died from the attack. He didn't want to do this, but he knew he had to.

And so, it was set. He would seal the fox inside of Naruto. To this, Kushina was outraged. She struggled in the chains that were bounded around her from the Adamantine Sealing.

"No Minato!" she yelled. "Don't seal it inside of him! Think about what'll happen to him! Remember how I was treated because of that demon? I don't want our son growing up like that! And he can't take that much chakra into him. Naruto could die! Please! I'm going to seal it inside of me! I don't care if I die. If I do, at least that monster will go down with me!"

Minato shook his head. "Then I'll seal half of its chakra inside of me," he told her. "I don't want him to grow up without a mother. I want you to be there for him as he grows up. And besides, you'll be there with him during his rough times. Naruto will grow up to be strong, you'll see."

A smile grew on his face as he spoke. By that point, Kushina seemed convinced. She nodded to him, tears begging to drop from her eyes, and then it began.

He began weaving signs with his hands, concentrating hard to make them perfect as possible. Minato could not mess up this part, and if he did, it could mean the entire fox would be sealed in his son, thus potentially killing him.

When the final sign was weaved, he shouted, "Dead Demon Consuming Seal!"

The shinigami appeared behind him, partially tugging at his soul. The demon then was able to split the demon fox's chakra in half, with the Yin part of the fox's chakra flowing into Minato's body. The shinigami then let go of his soul.

The Hokage was drained after that. But he knew his job wasn't just done yet. He began once more to weave the signs. However, Kurama noticed this, and after noticing half of his chakra was missing, he realized what was about to happen. With an intent to kill the child, he shot his paw forward, claws extended. Minato and Kushina gasped, and, in a last stitch effort, placed themselves protectively in front of their child. In a flash, both were impaled by the fox's large claw.

Both of them muttered out their final words to their child, promising that they would always be with him, no matter where Naruto was. Gathering all of the strength he had left, Minato began to once more weave the signs.

"Eight Trigrams Seal!" he yelled with all of his might. And thus, the sealing began.

The demon fox could feel his chakra being pulled, so he struggled keeping still. It was like a vacuum, sucking him into oblivion. After a while, the fox could no longer keep his feet on the ground, and thus was thrown in the air. His soul and the other half of his chakra were pulled towards the baby. For Minato and Kushina, everything was working well.

However, just as the demon fox was about to be sucked into the child, a mysterious purple/pink portal opened in front of the baby. The soul and chakra of Kurama, which was suppose to go into Naruto, went into the portal instead. And shortly after, it closed, never to be seen again. All the while, Minato and Kushina watched in horror as the fox was whisked away somewhere else. They did not know where the demon fox went, but it was somewhere far away from here.

Before they died, they realized that what happened was not a failure. While the Nine-Tails was not sealed away in their son, it was sent somewhere far away from the village, which was important. Not only that, Naruto would not have to live with the demon inside of him while growing up. The only thing the two regretted was not being able to see him grow up and not be with him. And finally, after the amount of pain the two went through, they died together.

Sarutobi Hiruzen, previously known as the Third Hokage, arrived at the area a few minutes after they died. He saw both of their bodies, cold and still, and realized that they were dead. Hiruzen noticed the young child, Naruto, crying in a little basket. And there was no Nine-Tails in sight. His first assumption was that the demon was sealed inside of the child, but there was no seal mark on the child's body.

And from that day, Sarutobi Hiruzen took over as Hokage once more, Minato and Kushina were praised as heroes, Naruto took the last name of his mother instead of his father, and the village presumed the demon fox to be dead forever. (1!)


Meanwhile, in another dimension...

A somewhat young man strolled into the pet shop. He was tall, had black hair, a set of brown eyes, and wore a maroon kimono. His name was Hamato Yoshi, and today would become one of the best, and worst, days of his life.

A few weeks ago, he had just recently lost his wife and only child. They had been killed by Oroku Saki, otherwise known as the Shredder. In fear that he, who was once his brother, not by blood, would come after him, Yoshi had moved to New York, the place where Tang Shen wanted to visit all of her life. It would be fitting for him to move there, just for the time being, and eventually go back to Japan to rebuild the clan he had left behind.

Today, however, was a different story. After a nightmare he had during his sleep of that fateful night where he lost his family, he had decided to get a pet, in an effort to hopefully ease the pain and suffering in his mind. The question is, he didn't exactly know what type of pet to get. A dog would be too rowdy, and if he wanted to meditate, it would no doubt disturb him during his time of peace. A cat would be easy to take care of. Or perhaps he could get a reptile.

Coming upon the pet store, he saw a sign in the window. TURTLES 4 SALE. His mind was then made up. For some odd reason, he now knew what to get. A turtle would be easy to take care of. Heck, he could get two or three if he wanted to. Having made up his mind, Yoshi opened the door to the pet shop. There was a women there to greet him, with a name tag on that said, "Jane."

"Hello!" she greeted him. "Welcome! Can I help you find anything today sir?"

He nodded. "I saw the sign in the window. Do you know where I can see some turtles?" Jane grew excited once Yoshi mentioned them.

"Oh yes!" she answered. "Here, I can take you to them." She led him to the other side of the room where the aquariums were. In a small contained contained four baby turtles.

"Here they are," she said. "These four were just hatched a week or two ago. And they're brothers as well."

The turtles were slowly walking around and interacting with each other. Only, something was odd about them. The smallest one was trying to play with the biggest one, who was pushing him away. Another one was studying the water, making sure of whether or not it was safe. Jane picked up the smallest turtle.

"This one is the youngest," she said. "He's very interactive with his brothers. I've been him trying to get the other ones to play with him." She placed him back in the little tank, and grabbed out another turtle.

"This one is actually pretty smart. He's the second youngest. He likes to study his environment sometimes, and makes sure that it's safe." Jane put the turtle back near the water where it was before. She then picked up a third turtle.

"This one is rowdy sometimes." She chuckled a little bit. "He's very protective of the other three, but he can be angry at times." Jane put him back in the tank.

Yoshi noticed that she wasn't picking up the fourth turtle. He looked over to it, and saw where it was. Compared to the rest of the turtles, this one was rather sickly and unhealthy.

"What about that one," he said, pointing to the last turtle. Jane looked at where he was pointing, and sighed.

"This one, ironically enough, is the oldest one. However, when he hatched, he wasn't exactly as strong as he could have been. We're not sure if he'll live long or not. We've tried everything, but he just doesn't eat. He's just been getting worse." She paused for a moment, then continued.

"But, that hasn't stopped him from protecting his younger brothers. It's like he's leading them, to be honest with you. Though, I don't know how much longer he'll live." Jane ended off with a sad tone.

He had decided what he would do. "I'll take all four of them. I do not want them to be separated from each other. And, I want them all to spend as much time together as they can. Perhaps, all that young one needs is some love."

Jane was excited to hear this. And so, Hamato Yoshi paid for all four turtles, and left the pet store with four new additions to his family. As he carried the small turtles in the little aquarium, he felt as if a small piece of his heart had been restored.

He kept his eyes on the baby turtles for a second, and didn't notice the fact that someone had partially ran into him. Surprisingly, the figure kept on walking. Though something felt off about the stranger. When Yoshi had ran into him, it didn't feel like he ran into a person. It felt like he ran into something made of metal. Sensing something suspicious was about to happen, Yoshi followed the man.

The man's destination was a back alley. Yoshi hid behind one of the walls of a building. To his surprise, the stranger had met up with another man, who looked exactly like the stranger. The second man was holding a mysterious glowing container. He wanted to get closer, to see more clearly what was going on, but when he took a step forward, he accidentally stepped on a rat's tail. It squealed in pain, alerting the two mysterious men to draw their attention towards the maker of the noise. And unfortunately, they noticed Hamato Yoshi.

"Go no further," the first one said. "This place is a place where you are not allowed to be in this place."

He could hear the sound of more footsteps coming from behind him alerted his attention. More men that look exactly the same were coming closer to him. Yoshi instinctively tightened his grip around the container with the four baby turtles.

"We have been seen by you in this place," the second one said. "So this is not a place that will be left by you."

All four men began to close in on him. And thus, a fight began to ensue. However, what the men did not know, was that Hamato Yoshi was a very skilled ninja. And now he knew, that these men would not leave him alone.

(2) Holding onto the container for dear life, with the four baby turtles inside, Yoshi kicked his way through the men. He took on three of the men at once. However, one of the men went off to the side. He had a strange device in his hand. With a push of a button, the device hummed to life, and, in a manner that surprised Yoshi, a strange purple/pink gateway opened.

He punched one of the men, which so happened to to be holding the mysterious glowing container. The man had lost his grip on it. The container was flung into the air. Glancing behind him, Yoshi threw a shuriken at the device, hoping that it would be destroyed by it. And at that moment, time seemed to stand still. The container fell towards the ground, and shattered on Hamato Yoshi's head.

This caused the container to spill open its containments, smothering ooze all over the young man. And not only that, but because of the fact that it shattered on his head, it caused him to lose his grip on the small aquarium that held the four turtles. It fell to the earth, shattering as it hit the ground, causing the four of them to be thrown into the ooze. And at the same time, a strange reddish aura shot out of the portal towards them. The shuriken soon hit the device afterwards, closing the gateway completely.

The aura shot towards the turtles, in an effort to be sealed in some sort of body. The eldest turtle, despite being covered in the painful ooze and now changing into something else, and his sickly body, out of pure instinct, protected his younger brothers from the strange apparition. And that was when the aura flew straight into his body. The turtle writhed in pain as the aura went into him. However, no one seemed to noticed, as they all were experiencing pain from the substance. And, perhaps it was a good thing too.

One thing was for sure, the young turtle could not take that much amount of pain. With the substance now changing him into a humanoid turtle, and the apparition coming into his body, he could not handle the physical and mental stress. At last, his transformation was complete, and he fell forward, away from the ooze covered ground. His eyes slowly started to close, as his strength was immediately leaving him. Somewhere, he could hear the faint call of someone calling out to him. But he could not adhere to it. Finally, he faded into darkness.

The thirty-five year old man was no longer human, and his pet turtles were no longer normal turtles. The ooze had transformed him into a giant brown/black rat. The DNA from the rat he had stepped on earlier had influenced his transformation. For the turtles, they were no longer ordinary turtles. Now, they all had humanoid features and bodies. The strange men left abruptly, and were nowhere in sight. (2!)

Yoshi collapsed to the ground in agony. He stared at his hands, which were now different than before. The newly mutated rat screamed out in agony, as another wave of pain hit him. Once it was over, he pushed himself up, finding that he had more strength than he had before. Why though? He looked behind him, only for shock to come upon his face. He had a tail. Hamato Yoshi was now a giant rat.

Panic swept over him like a tidal wave. However, it was disrupted by the sound of crying. He looked over to the source of the noise, and saw three of the now humanoid turtles. They acted like human infants, and in a sense, begging for attention. Taking his attention off of his new form, he walked over to the infants, carefully minding his current form. He made it over there, slowly picking up the three turtles. Yoshi tried to soothe them, rocking them back in forth. Only, something was missing. There was a turtle missing.

The mutated rat looked around frantically, being careful not to drop the other three, who were squirming in his arms. Yoshi was mindful to not leave the alley, because if he was seen in his current form, then he would no doubt be taken away. For one thing, he knew that the last turtle was still in the alley, for if he had turned out like the other three, then he wouldn't be going anywhere soon. But what if those men took him?

For some reason, Yoshi had a new feeling for these turtles. It wasn't like a pet/owner bond. These turtles almost felt like children. Well, they now possessed human attributes, but he suddenly had a certain feeling to protect them, and find their lost brother. His new ears perked up, searching for any sound or noise that the young turtle could have made. And then, the sound of shallow breathing could be heard from the corner of the alley. Yoshi rushed over quickly to the sounds, and finally, he had found what he was looking for. Only, slight panic began to take over his system.

The turtle had passed out. He couldn't blame the young one, after the pain it went through. But, Yoshi remembered the fact that the woman at the pet store had said that this turtle was sickly to begin with. And he could tell that whatever the strange ooze had done to it, it was certainly not good.

The three other turtles squirmed in his arms, practically begging to be let go. The rat slowly set them down on the ground, and knelt down, putting a hand on the turtle's plastron to see if it was still breathing. And indeed he was. To his surprise, the other three turtles crawled very slowly towards the fourth. They gathered around their sick brother, hoping that he would be alright.

He was intrigued by the sight. All four were like a unit. One could not function without the other. When one was down, the other three waited for the last one. In a way it was like…

'A family,' Yoshi thought. He realized it now. They were his turtles. His responsibility. He had to take care of them. Even if it means risking his life.

Of course, they were still his pets as well. He did not feel a strong bond between himself and them. After all, Yoshi had literally just bought them. But, as they are and would've been, they depended on him. He would take care of them now, and perhaps let them go later. The mutant rat placed his hand over the unconscious form of the sickly turtle.

'Please young one,' he thought as if he was praying. 'Come back to us. Your brothers need you…'


A few months later…

Kurama slowly opened his eyes. He was tired and drained, and couldn't remember what had transpired previously. Well of course, he still knew who he was. He was Kurama! The strongest and powerful of all the tailed beasts! He would find why…he was caged in?

The heck? He thought angrily. If it was one thing that the demon fox was known for, it was his hatred. And oh was he mad. Not only was he no longer in the Hidden Leaf Village, but he was in some sort of giant cave, with stronger than iron bars keeping him in on one side of the cave. The cave itself was a shade of blue, with a small pond in the middle.

'What is this?!' He thought angrily. 'Someone has tried to imprison me! Huh! Well, they can't keep me in here for long. They'll pay for what they've done!'

The giant fox got up, and ran towards the bars. He rammed into it with all his might. The bars shook, but they still held. Kurama noticed this, and became angrier. So, he barged at the iron bars once more, ramming his head straight into the bars. Still, they did not move. He was getting frustrated.

After a series of attempts, the fox collapsed to the ground in exhaustion. He had tried everything. From ramming into the bars. From blasting a Tailed Beast Ball at the bars. Heck, he even cloaked himself in his own chakra and ran into the bars. Sure, it left him with a painful headache afterword, but Kurama still had to try. Unfortunately for him, nothing worked. So where the heck was he?

Kurama stared at the iron bars before him, noticing the middle bar was larger than the others. Getting up once more, he walked over to the bars. The fox slowly stuck part of his head through the bars, not entirely, but able to see whatever was on the middle bar. His could feel his chakra being tugged on as he did it. Nausea rose in his throat as an idea of where he could be surfaced in his mind. The fox turned his head and looked at the middle bar. His eyes widened in anger and horror. It said Eight Trigrams Seal. Then, the memories came back to him. He had been sealed. Inside of someone. By the Hokage.

"MINNNNAAAAATOOOOOOOOO!" the fox roared out in anger.

His attempt at killing the child before he was sealed away failed miserably. Now he was trapped inside this stupid brat of a baby. Oh, Kurama was mad. His chakra was fuming. Oh how he was waiting for the day to grab the child's chakra, tug at it, pull it out, kill the child, escape, and…

Through his anger, something felt odd to him. The fox could not sense the boy's chakra. This was something strange. Every living being had chakra. Even those with a little amount, Kurama could've sensed it. So, why wasn't he sensing it now? Being inside of someone's mind, he would've immediately felt it within an inch in front of him. And this is the Hokage's son! Minato himself had a large surplus of chakra. Not to mention Kushina had a ton as well, which meant their son would have that trait. So then, why was there no chakra?

Could the child be dead? No, that was impossible. If that brat was dead, then he would've been set free. Although, this is an Eight Trigrams seal. It would've taken him down with the brat. Or, possibly not, since he was still alive. But Kurama would've been able to escape. What is this then?

His ears perked up at a sound. It sounded like crying. But Kurama could not see outside of the child's mind. So the brat must be unconscious then. He looked in the direction where he heard the crying coming from. To his surprise, it was the child himself. Only, something was different. This child wasn't Minato's son, which, in his mind, was a relief. He did not feel like being shoved into the mind of the Hokage's son. Only thing was, who was this?

Kurama took a closer look at the baby, and seemed to be in shock. This was definitely not a human. Instead, this child had green skin. He was about the size of a human child, but he had a shell on his back. The young one was somehow able to enter his own mindscape which even surprised the fox.

'A kappa?' He thought. He was sealed inside a baby kappa? But that made no sense. Kappas were not known to travel to the Hidden Leaf Village. So then this could not be a kappa. And most certainly could not be a kappa's child. Who is this then? What had transpired during the sealing?

The lighting began to flicker in the cave. Kurama wondered what was going on. The child cried once more. And then, a strange voice encompassed his ear.

"Please young one!" A voice called out. "You must wake up! Please!"

The voice was… begging? One thing was for sure. Kurama did not recognize this voice. For one thing, it spoke English, a language that none of the ninja spoke, so that gave him some sort of idea where he was sealed in. Kurama could speak and understand English as well, so he could tell that he was somewhere else. Somewhere outside of the Land of Fire. But how did he get out here then?

The second thing he noticed was the voice's accent. It was clearly Japanese, only it did not sound like the Hokage or that strange masked man that controlled him. Third, it was begging for the young turtle to wake up. So now he knew a few things. He knew he was no longer in Konoha, no one from that village seemed to follow him here, and this turtle needed to wake up for some reason.

(3) His eyes widened as he came to a conclusion. Somehow, during the sealing process, his soul and chakra, which were mean got be sealed inside Minato's son, curse that Hokage, were transported somewhere outside of the Land of Fire. Somewhere they spoke English. Eventually he ended up being sealed inside a small humanoid turtle, who has no chakra. And judging by the voice that was calling out to the child, which may have been his father, Kurama didn't exactly know the details, he could now tell that the turtle was dying. And it was all because of him.

The fox hated to admit it, but he felt guilt, something he hadn't felt since who knows how many years of anger and agony. Normally in this situation, he would get angry, plot to take over his vessel, and use some sort of means to escape. This time, the turtle had no chakra. And because of that, when the fox entered his system, his body couldn't handle it, forcing it to shut down and go into unconscious. And somehow, during those few months, the child was able to enter his own mindscape at not even a year old. That impressed Kurama. A child with no chakra that could do groundbreaking abilities. And yet he wasn't going to live long enough to test those abilities.

Kurama felt sorry for the turtle. He was dragged into a war without any of its own knowing. Sure it would've been different with Minato and Kushina's son, but this...the fox was in an area that presumably never even heard of ninjas. The turtle was dragged into something that probably was never heard of around here. And, in a sense, the child reminded Kurama of himself as a kit. When he and his kin were released from the Ten-Tails, Kurama suffered the most, as he was almost like leftovers from the beast. He was sickly, and hardly was able to move on his own. The fox almost had given up, but with some love and encouragement from the old man, he was able to recover dramatically.

He missed the old man, and now it seems like a situation like this is happening again. The old man hadn't given up on him, and this voice isn't going to give up on the turtle either. The young one has great potential in store, and surely he would not let it go to waste. Kurama had decided what he was going to do.

Slowly, he turned around and let his nine tails face the bars of the prison. One by one, each of the tails slowly made their way out of the prison. However, the seal was holding them back ever so slightly, and Kurama had to work hard in order for them to reach out. As the tails got closer, the pull of the seal got tighter.

'Stupid Hokage,' he thought. 'I will not let some stupid seal hold me back!'

Kurama struggled and shook as his tails stretched and reached out towards the infant. Finally, his tails could not reach any farther, and only hovered inches above the turtle's head. To his surprise, the turtle stopped crying, and his eyes opened, revealing cerulean blue irises. These were similar to those of Minato and his child's irises. The turtle looked interested in one of Kurama's tails. He reached out in interest, grabbing ahold of one of the tails.

'This brat is already putting his trust in me, Kurama noted.

He smirked at the thought. The fox lifted his tail gently, as the little turtle clung to it for dear life. He slowly brought him back into the prison where he was currently being held. His tail lowered to the ground, as the infant was carefully placed down so he wouldn't get hurt. The fox then thought about what to do next.

'The kid has no chakra,' he wondered. 'So with the addition of me being sealed inside of him, it is killing him. So, if I were able to take some of my chakra, give it to him, and have him make it his own, then he would survive.' Kurama shook his head.

'Of course, there are going to be some side effects from this, but it is the only way to save him.' The turtle wasn't scared of the giant fox at all. Once again, he latched onto one of the tails playfully, snuggling close to it to be warm.

The best way to transfer his chakra was through one of his tails. So, he set the turtle down on the ground once more. One of his tails came down towards the boy, who did not look intimidated by it at all. The tip touched the area where the turtle's stomach would've been if it wasn't covered by a shell. A strange, small red aura flowed out of the fox's tail, and into the tiny body of the turtle. The infant laughed in delight, as it gave him a happy feeling inside of him.

Around the cave, the light no longer flickered. It became stronger, no longer dimming the cave. The turtle himself was looking healthier, no longer supporting the grayish-green skin, but instead a more darker green hue. Kurama was satisfied with this. Not only was the infant able to hold chakra, but he was able to hold a small portion of his own chakra. That, in it of itself, surprised him. He thought the child would've died, but it is holding out through the process.

Finally, the red chakra stopped flowing from Kurama. He lifted his tail away from the child. The turtle looked way healthier than before. Healthy enough to live. The fox smirked.

'Heh! This brat better be thankful I saved his life!' The infant begged for one of Kurama's tails to come back and snuggle him. Said fox sat there in confusion at what the infant wanted.

"Nani?" Kurama spoke to the infant. "What do you want from me?!" The brat was beginning to bother him a little, making strange noises at him. His tails moved in agitation as anger began to rise in this body. The infant watched the nine appendages in interest, wanting to get close to one. He crawled slowly towards the giant fox. In response, said fox placed all nine of his tails in front of him in defence.

"No!" he roared. "I am not going to...huh?" Despite the fact that he used his tails as a defence weapon, the turtle did not think that was the case. Kurama stared down at the turtle in awe, as the infant did something he never expected. The turtle was hugging one of his tails. Not in anger. Not in fright. But in pure innocence.

'How could he not be afraid of me?' Kurama thought. 'Me?! A Tailed Beast?! All nine of us are feared, and yet…' He looked at the young turtle once more.

'It's probably because he's young. That's got to be it! I am not going to believe…!' The sound of soft breathing could be heard. His eyes trailed to the turtle, who had fallen asleep next to his tail! He felt a rush of heat rise in his cheeks. His ears lowered in embarrassment. It was definitely a good thing none of the other Tailed Beasts were here. Kurama sighed.

"I'm growing soft, aren't I?" he complained.

The turtle's body began to glow softly. Kurama realized what was happening. The child was waking up in the real world. This meant that the turtle would disappear from his mindscape. The glow intensified, and the turtle was gone. The giant fox sighed in relief. He lied down in the ground, feeling sleep come upon him.

But, there was another feeling that was aching him. The fox hated to admit it, but he felt lonely. He had actually liked the turtle's company? Kurama shook his head in disagreement.

'No,' he thought sadly. 'When he grows up, he will fear me. Just as every human does.' His ears ears drooped, and his eyes began to close, however, a light encompassed his vision. Kurama grunted, as the light consumed him. (3!)


Same time, a few hours later…

Yoshi waited by the young turtle with patience, as well as trying to control the other three turtles next to him. The eldest turtle had been unconscious for a few months, and showed no sign of getting better. He had nearly lost him just a few hours ago. Yoshi begged for the turtle to not give, and thankfully, a faint heartbeat was heard. And after he made sure the heartbeat was stable, he tended to the other three turtles in their new home.

During that time, he had been constantly moving himself and the little turtles around the city. Each time they were discovered by the mysterious men and some robots, they moved. Yoshi didn't have a choice. Otherwise, they would've been killed. As much as he didn't want to move the unconscious turtle, the rat knew he had to. After an encounter with the strange men, the rat and the young turtles nearly died as the encounter left them being thrown into a sewer and sucked away. Now, they were living in an abandoned subway station, and so far, the mysterious men haven't detected them as of yet. For now, he focused on watching the unconscious turtle.

By that time, Yoshi was deciding on giving them names. He had been taking care of them for a while now. It would be a good thing, since then he would be able to differentiate them. The three turtles tugged at his clothes, and were starting to begin to teethe. Yoshi picked them up and set them on the ground. He grabbed a huge, cobalt book out of his box of personal items. The rat sat down, as the three turtles crowded around him.

"When I was a child," he began. "I wanted to be an artist. So, it seems appropriate to name you after the masters of my favorite period of art. The Renaissance. Perhaps then, you will grow up to be something great."

Yoshi glanced over at the unconscious turtle, who he had wrapped up in a blanket. He placed the book on the ground in front of the three turtles. It opened up to a random page. The three crawled up to it, placing their small hands on three of the artists on the page. Each looked excited, as they were about to gain something.

"Hmm," he hummed, staring at the three. "I will name you." He pointed to the first turtle.

"Donatello," The turtle put his hand up to his chin.

"Michelangelo." The second turtle stuck his tongue out in response.

"And, Raphael." The third turtle smirked in satisfaction. Each of them began to giggle at their newly acquired names.

He smiled at their laughter. Then, deciding that the day had been long enough, he quickly tucked the three turtles into their own separate bed, away from their brother. It was not the fact that the unconscious turtle was contagious or anything. Yoshi kept him away so the other three couldn't hurt him in this state by accident.

The rat remembered that day well. It was a few days before they were discovered once more in an abandoned warehouse. He had seen their talents, as Donatello had turned on a light, and all three of them began to copy his motions as he practiced his ninjutsu. And sometimes, the three brothers would come over to their brother and try to play with him, only, he wouldn't wake up.

It was sad to see their eldest brother not wake up. Yoshi felt heartbroken at the sight. There was nothing he could do. He was unable to take him to the hospital because of what he is, and he had no medical equipment for the same reason. The rat even administered the Healing Hands, and all that he was brought with was a searing fiery pain to his hands. Yoshi pulled his hands away immediately, and had to wrap his hands in bandages because of that.

He decided that it would be best to head in for the night. The rat had already put the other three turtles to bed. And now that the unconscious one was stable, it was best for him to rest as well. After all, he would need all the energy he could get in the morning, when the three turtles woke up as well.

(4) Just when he was about to fall asleep as well, a little moan was heard. His ears perked up. Could it be? The shuffling of a blanket could be heard as the little turtle squirmed around in the blanket. Yoshi ran over to the little box in anticipation.

'Please,' he prayed. 'Please let this be the day that my son wakes up!'

In the turtle's mindscape, the light dissipated and Kurama could see again. Only, he wasn't seeing a lit blue room in front of him. Dark gray fuzziness came into his view, as a mysterious figure stood before his eyes. The fox realized then. He was seeing through the turtle's eyes! He didn't have control over him, but he was able to see what the turtle was seeing.

The turtle began to open his eyes. Cerulean irises with a tint of red came into view as his eyelids rose slowly. Yoshi stood over the box, watching the magnificent scene before him. Finally, the turtle's eyes opened completely, clearing away the blurriness. Kurama's eyes widened, and shock filled his face. He was definitely not in Konoha anymore.

Above the turtle was a figure. And this figure was a giant rat with black/brown fur. The rat stood taller than a man. He had a maroon kimono on with black flower embroideries. It was the symbol of a clan. And as far as Kurama knew, this clan did not exist in any of the lands of shinobi. The surrounding area was somewhere underground, and it definitely wasn't the Hidden Rain's underground. This place...it was too advanced.

"Welcome home, my son," he said to the turtle.

The turtle's eyes widened as he noticed Yoshi. And to his surprise, the little one jumped out of the box and ran away on all fours in fright. He ran up the stairs to the soon-to-be-built dojo that Yoshi was working on. The rat stood there in shock. Sure he knew that his other three sons were not as slow as regular turtles, but this one was fast!

"Wait!" he called out to the young turtle. Yoshi went up the stairs to find his son.

Meanwhile, Kurama was taking in the new surroundings of this new world. This was definitely not even close to looking like his home. It was like an entirely new dimension. Though, one thing still confused him. Why was the turtle running away from the rat? He wasn't scared when he gave his chakra and he met the fox for the…

Oh. Oooooohhhhh. Now he understood. He didn't exactly know much about children, but something was different from his meeting with the turtle and the rat's meeting with the turtle. The turtle didn't fear him, and when he saw the rat, he ran. So, did that mean...

'No!' He thought. 'I am not the brat's father! I do not intend on taking care of that...thing!'

The little turtle ran into the room, and looked around. There wasn't much to it, other than the carpet on the floor, the paper-like doors on the end of the room, and surprisingly, a rather large tree in the middle of the room. Sunlight glistened through the tree. The turtle, as well as Kurama who was viewing through his eyes, stared in awe at the sight before them.

It was cut short, however, as the sound of running feet could be heard behind the turtle. The young one picked it up very quickly, and ran once again on all fours towards the tree. He hid behind it, hoping to allude his pursuer. Kurama sighed.

'I think he inherited more than a few side effects,' he thought.

"My son," Yoshi said, as he entered the dojo. "Please, do not be afraid. I am not going to hurt you."

His ears perked up, as he began to hear the sound of whimpering. He turned, and looked behind the tree in the center of the dojo. There, curled up in a ball, was the little turtle. The young one quivered and shook in fear as the giant rat came closer to him. This made Kurama worried.

'This must be the turtle's father,' Kurama thought. 'And yet, the brat thinks I'm his...Tch!'

Immediately, the turtle was pulled back into his own mindscape. He sat in front of the giant fox, who was still behind bars. The turtle's eyes suddenly lit up in delight, as he ran swiftly on all fours over to the fox. He snuggled up close to one of his tails.

'Dang it, I have to get this stupid brat off of me and to his father,' he thought.

The Nine-Tailed fox lowered his muzzle towards the tail where the turtle was snuggling against. He gently pushed him away. In response, the young one giggled in delight, as he was being nuzzled by his "father." Kurama's ears lowered in annoyance, realizing the kid was starting to like him. He pushed the turtle outside the bars. After that, he retracted his muzzle.

Once the turtle realized he was no longer being nuzzled, he immediately ran back towards the fox. Only, Kurama pushed him away once more. This went on for a few minutes, until finally, the turtle looked up at him with eyes full of sadness. He was beginning to realize what was happening. The giant fox sighed.

"I am not your father," he said to him, hoping the turtle would understand. "Your father's out there." Kurama gestured to the entrance of the cave with his tails.

"Go to him. He needs you now." The turtle looked saddened by the fact that he was leaving the fox. But, it needed to be done. His tiny hand clasped around one of the bars. Kurama shook his head.

"Go," he said affirmingly. "Do not worry about me. I am not going anywhere. Hehe. We'll see each other again one day."

The young turtle's eyes widened in excitement. He laughed in delight. Kurama smirked. He nudged the turtle away from the bars. And thus, the little one began to make his way on all fours towards the entrance of the cave.

'Well, he certainly inherited more than just my chakra,' he thought, seeing the actions of the turtle reminded him of when he was younger.

The turtle reached the entrance of the cave. He looked back towards Kurama in hesitation. Said fox nodded for the turtle to go. The young terrapin smiled to him, and left the cave. Once again, the giant fox sat down and sighed in relief.

On the outside, Yoshi came over the the shaking turtle. "My son please," he began. "I have no intention of harming you. Open your eyes and look at me."

Said turtle, who had just exited his mindscape, opened his cerulean blue irises, and looked up. He became startled by the fact that the giant rat was next to him. The turtle retreated backwards, having his shell come up against the tree.

"It is alright young one," he said to him. "I promise you that I will never harm you in any way." The rat knelt down next to him.

"I do not know if you remember me at all or not, but I was the human who bought you from the pet store. I thought that you and your brothers would help me get over the fears of my past life, as my family was taken away from me. I hoped that you four would bring hope into my heart." He seemed distressed as he talked.

Kurama listened in, as he saw and heard the rat talking to the turtle. 'So he was once human?' The fox thought. 'Then what sort of curse or jutsu came upon him and turned him into this?'

He learned a few things in that moment. One, he was still in a world with humans. Two, this giant rat used to be human as well. Three, the turtle had three brothers. Four, the rat definitely lost his family somehow.

"After bringing you with me," the rat began. "I ran into a strange man. I sensed suspicion in him, so I followed him. I was then discovered, as I had stepped on a rat's tail. Soon, I was surrounded by four of them. As I fought my way through them as I was holding the container with the four of you, one of them opened up a strange portal to somewhere. I defeated the third man, who held a mysterious canister, causing it to be thrown in the air. I did not wish for them to get away, so I threw a shuriken at the strange device, destroying it. But what I did not notice was the canister landing on my head."

'Strange portal?' Kurama thought. He began to think back to the time when he was being sealed by Minato. The fox was suppose to be sealed into the boy, but some sort of pink/purple portal opened in front of the boy. And thus, Kurama's soul and chakra were sucked into the portal instead. Now, he was beginning to understand.

"And when it landed on my head, I lost my hold on the four of you. I did not mean for that to happen. The four of you fell into a strange substance, and covered me with it as well. I turned into what you see now, and you became who you are as well. Only, while the rest of your brothers were awake and healthy, you were unconscious. You have been this way for months, and haven't woken up."

Tears began to form in his eyes. "I nearly lost you a few hours ago," he admitted sadly. "You nearly died. But, you came back, and hope filled my heart once more that you decided to not give up on me, on your brothers. I felt happiness rise within my heart as I saw you awake. Please, I will never harm you."

And that was the moment everything clicked in Kurama's mind. He was definitely not home at all. If anything, he was in another reality. One where the life of a shinobi is unknown, and there is no war. Where animals don't speak, and where demons don't exist.

Now he knew what he had missed. Months. Months?! It had been months since he was sealed away in the turtle. And during before that time, some strange substance changed the man and the normal turtles into what they are now. Thus, during their transformation, the fox's spirit and chakra were sealed inside the turtle. And then, months passed, all the while the rat took care of the turtle, as well as his brothers. The turtle had almost died, and he would've, if it wasn't for Kurama. He couldn't imagine what would've happened if the turtle had died. The rat's heart would've been so broken to the point beyond repair. The other turtles would never see their brother again.

At this point, Kurama wondered if this was a weird coincidence or not. Well, at least the good thing was that he wasn't sealed inside the Hokage's son. But now, the fox began to think that he would never be able to get to his home again. For one thing, he now understood that the strange men that attacked the rat man were intending on coming to the Hidden Leaf Village, which he was attacking at the same time. If it weren't for the former human, then they would've came through the portal.

But...why? Was it just a means of escape? Or was it...something else? From what he could tell from the rat's story, those men had a strange canister filled with a mysterious substance. Perhaps they were planning on using it on someone in the Land of Fire. And if that stuff could do, well… that, then what else could've happened?

The turtle didn't budge at all, still staring at the giant rat in wonder. He wasn't shaking at all, all he did was watch, trying to see what the rat would do next. To his surprise, the rat stretched his out towards him. He still stood there.

"Go," A voice said in the back of his mind. It was Kurama. "Go to him. He needs you, just as you need him."

Trusting the fox's voice, the turtle brushed his head against the rat's hand. He smiled when he saw the turtle do this. Then, the young one ran up to him on all fours, nuzzling himself instinctively against his new guardian's body. Inside his mind was a fox with a smile on his face.

Yoshi smiled in happiness as his eldest son finally accepted him.

"My son," he said. The rat knelt down on the ground next to his son. "Thank you for coming back to us. Your brothers and I would not know what to do without you." The two embraced each other for a few minutes. Then, something occurred to him.

"You, my son, need a proper name," he said to the young turtle.

The rat picked him up in his arms and walked over to what appeared to be a shrine. At the bottom of the shrine was a large cobalt book. He placed the turtle in front of the shrine, grabbed the book, and knelt in front of the turtle. The rat began to flip some pages, until finally, he came upon one specific one.

"I have already named your brothers," he said to him. "You are the eldest of them, which one day, I hope you will learn to lead them."

He took the book and laid it in front of the turtle. The young one stared at the page intently, looking at the four names that were written there.

"Your brothers' names are Raphael, Donatello, and Michelangelo. One day, you will protect them, and lead them on the path of life. But, for now, it is time that I bestow upon you your own name. From this day forward, my son, you will be called, 'Leonardo.'" Kurama scoffed at the name. He would've thought the rat would give the turtle a Japanese name.

Nonetheless, the naming of the turtle began a certain chain of events. These in turn, would change his future family and friends. The world would depend on it as well. And, most of all, change a certain nine-tailed fox. Said fox could feel sleep drag him in. As his eyes began to close, he murmured something that the turtle could hear.

"Leonardo…" Kurama said, and was pulled into a deep slumber once more…(4!)


Author's Note

And thus ends the prologue. Ahhh! I'm so excited for this story! Now here's some information.

Ok, so I've watched the Naruto and Naruto Shippūden subs instead of the dubs, and am I the only one who thinks it's weird to write the characters speaking English? I don't know that much Japanese to begin with so I have to write them in English. Honestly that's the reason why I had Kurama mention that the shinobi spoke Japanese, even though I can't write it. Also tbf the English dub voice actors kinda sound terrible compared to the sub, or that's just me.

Most of this chapter is based off of the episode "Lone Rat and Cubs" from season 5. I do like the episode, but I wish Splinter didn't just open up to a random page and be like, "Hmm, there are four names on this page, four turtles, these are your names!" Or like how the baby turtles got trapped underneath the shopping cart in the water. THEY FELL AWAY FROM IT! But whatever. I think I might base some stuff off of some of the episodes, but there is going to be some non-canon stuff coming up.

When I mean that this version of Earth has no chakra, it has no chakra. Just to clarify. Chakra does not exist in the turtles' universe, nor does nature energy, or any other energy of that sort. Hence why people have normal lives and not throwing Rasengans all over the place XD Of course, Leo almost died because he was never exposed to chakra before, this happening when Kurama got sealed in him, and the fact that his mutation was also occurring at the same time. But, when Kurama willingly gave his chakra to Leo, he in a sense mixed it in with the Earth's version of lifeforce, thus making Leo have his own version of the nine-tails chakra. Oh, it gets better later on.

Anyways, enough of me rambling. What did you guys think? Good? Bad? Decent? I know there's not that many Naruto-TMNT crossovers (Unlike Pokemon-Sonic crossovers, shameless plug) but hopefully you guys like this!

Oh btw, the time is the same in Naruto's world as it is in the turtles' world. Am I hinting at Naruto meetup? Hmmmmmm…

Anyways, until next time, See Ya Universe!
