Hello everyone! This is something a bit different from me, because I have never written a crossover story before. But, I wanted to do it because my friend loves Doctor Who, and I am doing this for her. Hopefully this fan fiction will be finished for her birthday ^^

The first chapter will be based on the Doctor, but afterwards the rest of the chapters will focus on everybody, not just the Doctor. I put it in the Naruto category, because it is based in the Naruto world, and the main characters are Naruto characters. The Doctor will just be an added character to the team - not forgetting Captain Jack of course ^^

Disclaimer: I do not own the Doctor, the TARDIS, psychic paper, or anything to do with Naruto. ^^

^^ Enjoy!

Naruto/Doctor Who crossover

For my angelic, amazing, super-special-awesome best friend

The warm spring air blew through the blossoming sakura trees, the stray petals dancing across the soft breeze. The sky was a clear blue, and the feathery clouds drifted slowly and peacefully across it. The sun shone down from the heavens, lighting the world below with its brightening glow.

But this calmness could not last for long.

Suddenly, a flash of blue began to appear in mid air, smaller to begin with, but then grew each time it disappeared and then reappeared. The flash intensified with each passing second, and suddenly it began to take shape, forming a long blue rectangle with a small cylinder at the top. Then more features began to appear; a large sign labeled, 'Police Box' with the words 'Public Call' between the previous two words; two large windows; and a door, two doors to be exact, with a small sign on one, and small metal door handles on both.

Finally, after a few moments, the flashing stopped, and the huge blue box sat there amongst the sakura trees, completely still, as if it were trying to blend in with its surroundings, but clearly failing miserably at the task.

There was silence, until a series of bangs could be heard from within the blue box, and a voice, a very loud and confident voice, was shouting random commands and phrases, receiving no coherent reply.

Then, the banging grew louder, and then the box opened. A man poked his head out from the blue box, his eyes glowing with childish wonder and excitement. Sensing an adventure set out before him, he took at huge step outwards, and revealed himself to the world.

He was a fairly tall man, with spiky brown hair that sprang upwards, and a fringe that hung down from one side of his face. He wore a long brown coat, a blue suit and tie, and strangely enough, bright red converses, which did not at all suit his more or less smart choice in clothing. When he looked around the surrounding area, a look of confusion spread across his face, and he scratched the back of his head, as if he was contemplating something.

"Now hang on a minute," he muttered, "Where am I?"

He took a step further, and whipping a hand into a pocket, he retrieved a pair of stylish black glasses, which he immediately forced onto his head. Bending closer, he examined the sakura trees, and a wide smile quickly appeared on his face.

"Oo," he remarked, "This is definitely interesting. Amazing in fact…..no wait, amazing isn't the right word for it. What's the word? Ooh, it's on the tip of my tongue! Um…..fandabbytastic! Yeah, that sounds about right, doesn't it?"

He reached up and grabbed a single sakura petal from one tree and placed it carefully in the palm of his hand. The smile widened.

"This is a sakura blossom!" he exclaimed, "But how did I end up in Japan? I wasn't going anywhere near Japan! Or at least, I wasn't planning to. This is incredible! Donna, come have a look at this-"

He turned back to the blue box, and held out his hand, the kiddish smile still on his face. But he was staring into an empty room. There was no one there but him. His hand lowered slowly, and the petal fell gently to the ground. The smile immediately vanished from his face, and was replaced with a look of indifference. However, a sense of mourning was clearly evident in his harsh brown eyes.

He walked slowly towards the blue box, and leaned through the door, making sure that it was completely empty. All that was in there was a huge green tube that continuously glowed with a strange alien light, and a circular area of machinery around it. The look of indifference remained on his face as he closed the door and quickly turned away, shoving his glasses roughly into his coat pocket and leaving the blue box all alone in the clearing of sakura blossoms.

The petal was crushed roughly under his foot, and left, but not entirely forgotten.

He walked through surroundings forests, examining everything around him with amazement and intense curiosity. Every few moments, he would 'ooh' and 'ah' at various plants and animals, as if he were seeing them for the first time. He wandered through the forests for a long while, until suddenly, the forests ended and he emerged on a dirt road. He immediately stopped at the sight before him, his eyes glowing with excitement and wonder.

In front of him, was a large village, one of the largest he had ever seen in the human world, and it was alive with the mad rush of people, carts and the like. He gazed at the entrance to the village, and saw a circular sign at the top, with the kanji symbol for fire hanging proudly for all to see.

"This…..is incredible!" he exclaimed, "Even the word fandabbytastic wouldn't be suitable to describe this! This is unreal!"

Without any further wait, he sprinted forward, his coat flapping behind him in the wind. He couldn't wait to examine everything inside the village – the people; the food; the customs. After all, he had never seen a village like this before. He couldn't explain it, but he knew there was something different about it. And he wanted to know what it was.

"Hold it!" a voice cried in harsh Japanese.

He froze, stopping himself just before the village entrance, groaning in irritation. Who was trying to stop him from having a little fun now?

He turned, his hands aloft like he was being held at gunpoint, and said in perfect Japanese, "What can I do for you?"

His eyes widened as he saw two men sitting at a booth straight ahead of him, one of them with a bandage across his nose and black hair that jutted out in all directions, and the other with what appeared to be a black piece of cloth attached to his chin, and a fringe that covered most of the right side of his face.

"You can't go in there without seeing us first," the bandaged one stated.

He nodded slowly, and walked towards the two men in the booth, lowering his arms.

"Hello gentlemen!" he piped enthusiastically.

Both the men looked at each other in disbelief. The chin covered one said, "Who are you? And what is your business here?"

"Ah, right," he said, reaching into his pocket to grab his trusty psychic paper that would give him a fake ID, "I am Sora Otinashi, head of the medical clinic in my city. I am here to inspect your village's health codes, hospital and such. Your leader should be fully aware of my arrival."

He held the psychic paper in front of the two men's noses as they examined it closely. He knew he was pushing it, saying that their leader knew he was coming, but he was sure that that information would get him inside the village.

Both men gasped and stood up in respect, which made him jump a little in surprise. What exactly was written on the paper that had influenced the sudden change in attitude? Even so, it made him smirk contently.

"I apologize sir!" the bandaged one shouted, bowing deeply before him, "I did not mean to be so rude!"

"Ah don't worry about it!" he replied, "And you can just call me the Doctor."

"Of course Doctor, of course!" the other one said, bowing just as deeply as his companion.

"So, I can go in now, right?" the Doctor asked, pointing to the entrance.

"Certainly Doctor!" they both said in unison.

The Doctor nodded, and without wasting further time, he bolted it straight through the village's entrance, not giving the two men in the booth a second thought. Once he was properly inside the village, he stopped, rubbing his hands together with glee.

"Now, let's have some fun!" he exclaimed, before sprinting straight through the crowd of people, and vanishing out of sight.

The Doctor had been inside the village for a good few hours, and already he had learned so much.

The village was called Konohagakure, and it was a ninja village where they trained young children to perform incredible feats in missions that they were given by the general public from other villages or towns. When he had discovered that he was in a village full of ninja, he had literally jumped for joy. After all, how often was it that you could talk to real live ninja?

However, all of the high ranking ninja officials were off on missions or were swamped with paperwork, and were far too busy to talk to him, according to the offices. So, the Doctor had taken it upon himself to talk to the locals, and ask them all sorts of questions about their city and their lifestyles. He had spent the entire day recording facts and information on the village, not forgetting to spend a little leisure time around the village as well.

He had just finished talking to the owner of a restaurant called, 'Ichiraku' which served ramen, and was now heading towards the entrance to the village again, hoping to catch a ninja on his or her way past.

"I can't believe this place," he muttered to himself, "It's amazing! Full of different things! And yet I have no idea what the time period is. It's a ninja village, so I thought it must have been around 16th century, and yet they have televisions and headsets, completely 20th and 21st century technology! It's mind-boggling to say the least...."

He was completely lost in his own thoughts, so he did not notice the large crowd forming directly in front of him, and because of this, he walked straight into it, bouncing off and landing on the hard ground.

"Hey! What's going on?" he asked, bounding to his feet.

The Doctor tried pushing through the crowds of people, curious as to why they were crowding in that particular spot.

And then he saw them.

He gasped.

Staggering towards the large crowd, was a boy, who could not have been older than seventeen. He had bright blonde hair, the clearest blue eyes, and three lines on each side of his face. He was covered in blood, if it was his own or an enemy's, the Doctor was not sure, but the boy must have suffered some injuries, because he was limping and panting excessively with each step.

But he wasn't the person that had made the Doctor gasp.

In the blonde boy's arms, was another boy, who could also have not been older than seventeen. He had jet black hair that spiked outwards, and the palest skin. His eyes were closed, and his skinny frame was limp in the other boy's arms. He was unconscious, and barely breathing, as far as the Doctor could see. He was also covered in blood, but his injuries were far worse. One, a particularly nasty cut across his chest, was oozing a clear liquid, and the broken skin was red raw.

The blonde boy was struggling carrying his injured friend, so the Doctor ran forward, trying to push past the crowd once again.

"Help us!" the boy cried, "Help us please! He needs help!"

The blonde one finally collapsed, but still held tightly onto his friend, refusing to let go.

"They didn't tell us!" the blonde boy screamed, "They didn't warn us that this was going to happen!"

The Doctor pushed past dozens of people to get to the boys, reaching a hand into his coat pocket to retrieve his old friend - his sonic screwdriver. He sensed he was going to need it.

The Doctor stopped dead when he emerged from the crowd, and crouched down to inspect the cut on the black haired boy's chest. He carefully reached out and touched the red skin surrounding the cut, which made the boy hiss in pain. He retracted his hand, and inspected the clear ooze that had seeped onto his finger. He reached into his pocket and retrieved his glasses, which he once again shoved onto his head. After a few moments, he brought his finger close to his mouth, and then in one go, forced it between his lips to sample the strange looking liquid.

"What the hell are you doing?!" the blonde boy asked, his eyes wide with fear.

The Doctor smacked his lips, running his tongue over them to make sure he had properly tasted the goo. "Mmm..." he remarked, "That's a new one. Haven't tasted something like that before..."

"W-who are you?" the boy stammered.

"I'm the Doctor," the Doctor replied casually, leaning closely to the black-haired boy, holding his sonic screwdriver aloft, and pressing the button on the side to activate it. He quickly began scanning the boy, hoping that his screwdriver would detect any alien chemicals that were used against him. However, the scan came back negative. He paused. If the clear goo wasn't alien, then what the hell was it?

"What are you doing to him?" the other boy demanded, his eyes widening at the sight of the sonic screwdriver.

"I am scanning him to see if he has sustained any major injuries," the Doctor quickly lied.

"I can see that by just looking at him!" the boy cried angrily.

The Doctor ignored the boy's anger, and carefully placed his head on top of the other boy's chest, to check for a heartbeat. It was faint. The Doctor cursed.

"You! What's your name?" he asked, pointing at the blonde one.

The blonde one flinched slightly. "My name's Naruto. Naruto Uzumaki."

"Right, and what's his name?"

"Sasuke Uchiha," Naruto said sadly, gazing down at Sasuke with soft eyes.

The Doctor lifted Sasuke's right eyelid up, and began scanning his eye. Sasuke groaned softly.

"Sasuke, can you hear me?" the Doctor asked, "Hello? Sasuke, can you hear me mate?"

Sasuke didn't reply. The Doctor quickly checked his scan. It still came back negative.

"Right, we need to get him to your village's hospital. Immediately. He needs attention," the Doctor urged, putting his sonic screwdriver back into his pocket quickly, before anyone else could see.

Naruto nodded his head, and tried to stand up. But, the weight still proved too much for him, and he fell over. The Doctor rested a hand on Naruto's shoulder, and said, "You stay right here. The others can take your friend to the hospital."

"But-!" Naruto protested.

"No," the Doctor insisted, "I need you to stay here. I need you to tell me what happened to you and your friend."

Naruto's face fell as two ninja picked Sasuke out of his arms and carried him away towards the hospital. The Doctor slowly wrapped an arm around his frame, and lifted his heavy body off of the rough ground. Naruto's eyes stayed downcast.

"It's going to be okay," the Doctor said reassuringly, "They'll take good care of him."

Naruto looked at the Doctor harshly, his eyes burning with sudden fury. The Doctor removed his arm, and let it fall to his side.

"He better be," Naruto hissed, "Or I'm going to have a word with the Hokage. She didn't warn us about those......things."

The Doctor's eyes narrowed slightly. "What do you mean...things?"

"I don't know," Naruto replied, scratching the back of his head in confusion, "But I'll tell you one thing."

"What?" the Doctor asked, leaning towards Naruto in curiosity.

"They definitely weren't human."

So what did you think? I hope it was okay! ^^ I hope that I portrayed the Doctor's character like David Tennant does in the series! (The Doctor in my story IS the David Tennant Doctor, because I haven't watched anybody else as the Doctor before! ^^)

I don't usually watch Doctor Who, so if I get something wrong, like the uses of the sonic screwdriver or something, please tell me, so that I can correct it in the future. ^^

I hope you enjoyed the first instalment!

The rest is on the way soon!! ^^

See you later!
