A/N: OK, this is my first fan-fiction on here so please be nice! I'm English, so it's English spellings on this (but then, it's Doctor Who…so what did you expect?)

I do not own Hetalia or Doctor Who. If I did, they wouldn't be nearly as awesome!

The World Conference was over for another day. First to leave, as usual, was America, dragging that poor clone of his along with him. Other countries soon began following his lead as, in dribs and drabs, until only a handful remained, Italy rocked on his heels as he waited for Germany to come back and finish clearing his paperwork. He frowned as he thought about Germany, there was something about him that had always seemed vaguely familiar, like a distant echo upon his past, but he pushed the thought to the back of his mind. That wasn't possible, right?

Prussia watched this with slight amusement, still the longer it took Italy to realise the small secret he was holding, the better as far as he was concerned. This feeling didn't last though, as he looked at …well, they were hardly his "fellow" nations were they? Not anymore…Hey, what was with this downer? He was obviously so awesome that the world just couldn't handle it, he laughed to himself

Romano also watched his brother dreaming, doubtless about the potato bastard, what did Veneciano see in him anyway? Stupid fratello! Lost in thought, he failed to notice Spain until he wrapped him from behind in a hug

"Romaanoo~"

"Get off, tomato bastard!" He jerked his head back violently, cracking Spain under the chin

"Ah! Romano!" Spain's eye's watered from the unexpected pain

"D-don't cry, bastard! Che, you shouldn't sneak up behind people like that!" Dammit! He hadn't meant to hurt him like that! Ugh, but it wasn't like he could show Spain that he was concerned. He'd dug himself in this hole when he'd first met Spain. Why was he always trying so hard to make out like he didn't care, and now this perception of him was buried too deep.

Spain laughed off the pain, rubbing his sore chin. He was glad that Romano couldn't see his face. He wished he wasn't bound by all these rules and meetings, he wished he could go back to the way it used to be king of the sea. He smiled, looking at Romano, and wondered how he would look in pirate attire. Maybe he would suggest it later…

France laughed to himself in amusement at Spain's antics; it amused him to see l'amour at work! Although, really, Romano was worse than the rosbif at admitting his feelings sometimes…ah, yes…the rosbif…it was true he and Angleterre were getting along better these days, but still, it was so hard to forget

"Jeanne"

Japan cringed from the exuberant display that the Europeans seemed to delight in. Honestly, it was a times like this that he missed the Isolationist era, when he had been left to his own devices to do as he saw fit. But of course, America and his ships had changed that…

England surveyed the room and sighed, then frowned as he noticed a wallet on the chair next to him,

A weird screeching noise suddenly echoed through the conference room, England straightened in alarm

"Oh, please not him…"

A blue shape began materialising in the corner of the room, Switzerland drew his gun (how he managed to get them in the room was a constant mystery to everyone else) but England reached out to stop him

"No! Don't shoot!"

"What?"

The shape solidified the words Police Public Call Box printed along the top. Suspicious glances fell on England as he made his way over to it. The door opened to reveal a tall brunette, who grinned cheerily at the assembled nations

"Ah. Hello!"

England clenched his fists and gritted his teeth as he tried with all his might to stop himself from launching himself at the man and strangling him.

"Doctor"

"England"

"What are you going to destroy this time, git?"

This drew disturbed looks from the other nations. Destroy? Who was this man?

"Hopefully, nothing! I was tracking a disturbance is all, but…"

"Another hole? The last one nearly ripped me apart!"

"England." Austria said levelly, trying to calm his shock at a box with a strange man in materialising out of nowhere "Who is this man? And how do you know him?"

England turned; he'd almost forgotten where he was "Err…that is…" How could he even begin to explain? Oh, this is an alien a time travelling alien who's destroyed my capital several times and gives me nothing but grief. It would be the fairy argument all over again.

"Hello! Sorry to burst in on your meeting like this, I'm the Doctor" the man said, flashing the confused nations a mega-watt grin "I was just-oh"

A metallic tang flavoured the air, suddenly what looked like a bolt of lightning flashed across the table in the centre of the room

"What the-?"

The Doctor darted back to the TARDIS "Run!" he yelled, but it was too late, the air in front of the table appeared to rip, revealing a black emptiness. It acted like a black hole, sucking in everything in its path. Switzerland felt his grip shift as he fought against the wind. One by one the countries fell into the time stream; they felt their bodies changing, aging in different ways. The Doctor watched in horror. He shuddered to think what effect this would have on their countries.

He knew of nations of course, you couldn't hang around Earth as long as he had without being at least aware of them; however the only one he really interacted with was England, and they weren't on the best of terms (But really, it wasn't like he chose to have destruction follow him. Mostly). However, he was fairly sure that this couldn't have a good effect on the Earth.

Suddenly, the door to the conference room opened

"Sorry guys, forgot my-"

The Doctor straightened as a blonde man wearing a bomber jacket entered the room

"Huh? Who are you?"

*5 minutes ago outside the conference room*

"Ah damn!" America cursed as he searched the pockets of his favourite jacket

"What's up, America, eh?" Canada asked shyly

"Left my wallet in the conference room. I'll just go back up to the room and get it"

Canada sighed. Honestly, America could be so absent minded sometimes! And he wondered why his economy was in such a mess. "Want me to come with you?"

"Nah, it's fine, I'll only be a minute, just wait here"

America wandered back the way they came, into the conference room "Sorry guys, forgot my-" He stopped in the doorway, the room was empty, apart from a strange man standing in the doorway of a weird blue box

"Huh? Who are you?"

The man ignored him, him! The hero! He seemed more fascinated with a blue penlight that was making a buzzing noise.

"Hey! Weird dude!"

The man began muttering something to himself, something about rift particles

"Hey, buddy! I'm talking to you!"

The man looked up surprised, as if he hadn't noticed him

"Ah, yes, hello, I'm the Doctor, if you don't mind, I'm trying to repair the fabric of time and space itself here, do you mind?"

"Dude! Don't you know who I am?"

"I'm assuming someone important to this time period? I haven't been keeping track of current events"

"Dude, seriously? You're talking to the US of A here, dude!"

"Oh yes, I've heard of you"

"You've heard of me?"

"I always get a gun in my face when I go to yours though. Except when I went to the Moon landing, that was good"

"Yeah, that was sweet. Hey, d'ya happen to know where everyone went?"

"In a word? No."

"Oh, OK. You seen my wallet?"

"Err…oh…that probably went where they've gone"

"Oh, OK. Wait, what?"

"Ohh, this could take a while…umm, just step inside my office for a sec"

"That blue box there? If you insist dude, but it's gonna be pretty cramped with just the two of us in there-whooooooaaaaaaaaaa"

The Doctor watched in amusement as the American ran around the box and back in…then back out again and around the other way

"Man, this is trippier than when I ate Canada's 'special' brownies"

The Doctor mouthed along as he dragged the American to the console, America shouting "It's bigger on the inside!"

"Is it? I hadn't noticed, now this is my TARDIS, stands for Time And Relative Dimensions In Space. To answer the questions I know you want to ask, yes, I'm an alien, yes, this is a time machine, yes, we are going to use it to get your friends back and no, I don't know where your wallet is but I'm sure it'll turn up. Hey, don't touch that!"

America guiltily withdrew his hand from the console "Why, what would happen?"

"Um" The Doctor paused "Not sure actually, either you'd kill yourself and all your ancestors, or a cup holder would come out. Not sure which!"

"It's very Home Depo isn't it?"

"Nothing wrong with that!"

"So where is everyone, Doctor…?"

"Just the Doctor. And I don't exactly know, but my guess is they have been randomly distributed along their own personal time stream"

He paused and saw America's confused face

"They've gone back in time"

"Oh! Like in Back to the Future?"

"That is the essence of what I'm saying, yet wrong in every detail"

America was sunk in thought for a while, before coming out with "But most of them are like, really old! I'm talking dinosaurs here, dude! We can't go through all of history, that'll take foreeeeeveerr!"

The Doctor gave him a strange look, he was beginning to understand where some of England's grumpiness came from "Yes, I know. That's why I'm trying to narrow it down now using the DNA transferor"

"Dude, you so totally just made that up"

The Doctor scowled "Fine. Just think of it as my satnav" He sighed "I just hope we find them before they cause too much damage"

"What do you mean?"

"Well, think of it like a wave tank. Any changes they make back then will ripple through time and interfere with the now. And if it happens too much the universe will tear like rice paper"

America frowned "IIII don't get it, the universe is made of paper? I thought it was like a tank?"

"Oh, for a rubber sheet and some lead weights. It's the butterfly effect, America"

"Ohhh, why didn't you just say that?"

America settled back to watch the strange alien (And he certainly was strange! Nothing like Tony) when a thought struck him

"Canada!"

"Who?"

"My brother! I left him waiting for me outside the conference room! He already gets annoyed at me for forgetting about him!"

"Here, hand me your phone"

"Don't break it, it was a gift from Japan"

The Doctor pulled out the weird penlight again "I'm not going to, I'm just- increasing your coverage"

America stared "Are-are you hacking my phone?"

The Doctor threw him back the phone, "Ring your brother and tell him that if anyone starts getting weird new memories or begins acting strange, he's to call that number immediately" he said, surprising America with his sudden military demeanor "That could be key to finding out where people have gone" As he spoke the console began pinging "Speak of the devil, one of them's turned up! Allons y!" he cried, pushing random levers and setting the TARDIS in motion to the past.

A/N: OK, so this is an idea that's been floating around my head for a while now, this is going to be co-written by me and my friend Samstar1990. It's basically going to follow America and the Doctor as they try to find all the Nations again, but of course, things are never that simple…
