The Doctors and the Nanotech - A Doctor Who and Revolution crossover

Things to understand prior to reading this fan fiction:

Revolution is set in the near future where a last-ditch weapon had been used, the nanites. Initially just robots, they were given two commands, absorb all electricity and replicate. In a matter of hours after they were unleashed they filled the entire world, even existing in the breathable air. A group went to a remote control tower which still functioned to control the nanites. As they tried to shut them down, the power returned momentarily, but something happened to the nanites to make them self aware. The events in this story take place directly after the series finale, which ended with a scene showing the nanites controlling a massive mob of people in the town of Bradbury, Idaho.

The Doctor is from a species of time travelers known as Time Lords. The short of it is that they have two hearts, look just like humans do (or rather, humans look like them), and when dying they can regenerate themselves, changing every cell in their body and taking on a new form

The Ninth Doctor, the first encountered in the story, has recently regenerated following a war between his race and the Daleks. To end the war and save the rest of the universe he had to use a weapon so powerful that it destroyed both his people and the Daleks. He now must face that guilt for the rest of his life.

Chapter 1 - Prelude

Bradbury, Idaho. Aaron tried to convince himself that it was too far of a trip just to lose a fight to the nanotech. Here in Texas he perhaps could live out his life and maybe, just maybe, it would leave him alone. But no matter how he tried to run from his date with destiny he knew he would have to find a way to confront and destroy the nano.

In the past year he'd seen just how dangerous and unpredictable the nanotech could be first hand. It started with visions of soldiers bursting into flames - visions that he soon found out were the reality. For a short time the nanotech listened to him, even looked to him for guidance. But when Dr. Horn killed Cynthia he lost control. He'd ordered the nano to kill the soldiers and Horn, and he watched Horn burn there before his eyes. But when Aaron begged the nano to heal Cynthia it had left him helpless. In time the maturing nano turned the tables, this time ordering Aaron around, and possessing the body of his ex-wife, Priscilla. Together with Rachel he freed her from its hold, and as it left her body Priscilla saw a vision of the nanotech's plan. It all seemed too impossible. How could they defeat a foe that was everywhere? It was in the air they breathe, and it seemed to know all their moves before they made them.

No. Something had to be done. He had to try.

Aaron was tending to a sleeping Priscilla when Miles walked in. "Well, that's it. We're at war, Aaron. The Republic of Texas issued orders to kill any Patriot on sight. We took back Willoughby last night. I'm not sure how it'll -"

"Miles, there's something … bigger going on …"

Miles tone was sharp. "Bigger, Aaron!? What the hell could be bigger than taking down these maniacs?"

"I can't … Can you gather everyone together? Just the people you trust. Even Monroe, if you think you can trust him. I'll explain everything then." Aaron seemed shaken to Miles, much more so than his usual cowering self. Whatever it was, Miles had never seen him like this.

SCENE CHANGE

The Ninth Doctor was finally starting to feel like the hero he used to be. After the devastation of the time war and having to exterminate… no, annihilate, his own people alongside the Daleks he thought he'd forever be jaded and full of guilt. Then he met Rose, a simple 21st century girl from London, England on Earth. Typically he felt that humans acted like "stupid apes", but Rose was … different. She had an innocence and purity that seemed to fill in the gaps the time war had left in his hearts. He was better with her.

Still, he needed time on his own now and again, and at her request he dropped Rose off outside her mother's flat to ring in the New Year of 2005 with her. He'd been invited, of course, but declined. Good ole Rose. She was truly unique.

Nine put the TARDIS into a low orbit around Earth and activated the temporal scanners. "Any chance for an adventure, I wonder?" As if having read his mind the TARDIS displayed an anomaly in the year 2030. The anomaly seemed to cover the Earth, but there were two points of great intensity, both in North America. The smaller one was centered in Texas, and the much larger one in Idaho.

The Ninth Doctor mused. "Right then, cowboys or potatoes?" he said to no one in particular. He reached into his leather coat and pulled out a British pound. He balanced it on the top of his right hand and gave it a flick. "Tails we pick potatoes". It landed in his other hand and he slapped it down atop his right. Heads. The doctor smiled as he set the controls for a location outside of Willoughby, Texas in the year 2030. He briefly considered finding his leather chaps and cowboy hat, but decided that he couldn't pull off the cowboy look in his current incarnation.

2030. That was three years after the first great blackout of Earth. But a scan revealed there was only one great surge of power in Bradbury, Idaho. The rest of the Earth was dark. Strange, the power should have returned over a year ago. 'Maybe these cowboys will have some answers', he thought, and engaged the engines.

SCENE CHANGE

Miles had gathered everyone outside of the gas station they had been using as their safe house. "Okay, Aaron. Everyone's here. Now tell us what's more important than the war against the Patriots."

"Yeah, Stay Puft. Tell us why we're here instead of out killing those Patriot bastards!"

Oh good, it seems Monroe is being his usual charming self, Aaron thought to himself. He took a deep breath. "Look, I know you guys probably think I'm crazy, and I know you think I'm a coward. But something much bigger is happening than the war with the Patriots." He could barely hold himself together. "The nanotech … the tech that took out the power in the first place … when we turned it back on, something happened."

"Yeah, that psycho Patriot Randall Flynn dropped a nuke on Philly!" said an enraged Monroe.

"Yes, but … " Aaron stabled himself on a nearby icebox. "that's where things get weird. When the missiles were launched I frantically wrote a subroutine to have the nanites specifically target and depower the nukes. They were supposed to just fall out of the sky. I sent the commands over and over, but it wasn't until after the missiles hit that the nanites responded. Just before the power went out again I saw a message on my screen. 'Thank you, mummy'"

Charlie was more concerned about the war, and in recent months she found she had little patience when people didn't get to the point. "So what are you saying, Aaron? It thinks you're it's mommy?"

"What I'm saying is that the nanotech is alive. And over the past year it's become more and more sentient. And with its growing intelligence its plan to enslave the human race also grows."

Monroe scoffed. "That's total bull#* !"

Rachel spoke up. "It's true. The nanites took over Priscilla's body. It performed experiments on humans in a house a few miles from here. I saw it with my own eyes. We barely saved Priscilla, and as the nano left her body she saw what it was planning next."

Miles had heard enough. "That's great, Rachel. Just great. It's bad enough that we have to fight these crooked psychopaths pretending to represent the United States. Now you're telling me that our bigger enemy is one that exists in the very air we breathe? I can't come up with a plan to fight that. I can't-"

Just then the wind picked up, and a terrible screeching noise began to fill the nearby air. It sounded like a cross between electricity arcing and a dinosaur roaring. Aaron and Priscilla cowered under the awning of the gas station. A blue box began to phase in and out on the road until it finally fully materialized. Miles and Monroe drew their guns, and Charlie aimed her bow at the distinctly British box. The door opened.

"Maybe you can't fight the nanites, mate. But I can. Hello, I'm the Doctor".
