Hey there everyone! I've been a fan of TMNT and Doctor Who for a long time now, so I thought 'why not put them together'? Hope you like it!

OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

It was a dark evening in New York City. Ominous rain clouds threatened to split open as they rolled across the sky. A silhouetted figure darted along the alleyways, trying hopelessly to flee his attacker. A menacing, high pitched buzzing followed him everywhere he went.

"What do you want?!" he cried, groaning in despair when he came to a dead end. He gulped. Dead was just the word. The buzzing slowed, menacing, threatening, coming closer and closer.

"Please! I'll give you anything you want! Please let me go!"

"Anything?" The voice sounded raspy, almost buzzing. "Very well, human. I want only thiszzzzz." There was a pause; distant rumbles of thunder could be heard.

"N-name your price." A shriek of victory accompanied by a scream of terror and pain and death broke the heavy atmosphere. And all the wandering passerby would have seen is the shadow of a man.

The storm crashed into New York in full force, even halting the 'night patrol'.

"Leo, the wind's getting too strong! We're gonna have to turn back!" Donatello called, holding up his arms in a bid to fight of the wind. Leonardo nodded.

"You're right, Donnie! Nobody in their right mind would be out now! C'mon guys, let's head home!" There were no arguments, not even from the most hot-headed of the group. There was no point. The wind was now accompanied by driving rain and deep throated rumbles of thunder. And yet, Leo was still sure that he heard something else. Something in the distance, something foreign. Stopping momentarily, he looked out over the city, paying very little heed to the freezing October rain.

"Yo Leo! You frozen over there?" Raphael called.

"Huh? No, I…thought I heard something!"

"What?" Leo sighed. There was no point in saying anything in this weather. Maybe it was a good thing that they were heading back.

"Never mind!"

""""""""""""""""""""""""""""""""""""""""""""""""

The fact was, Leonardo had heard something in the distance, and it certainly was foreign. A rasping, grinding sound of ancient engines joined the crescendo of the wind, rising and falling in pitch in a steady motion, keeping time like the ticking of a clock…or the beat of a heart. Finally, with a soft thump, the blue 1950's police box fully materialised from the Time Vortex, along the shoreline of the Hudson River. There was a pause before the door opened. A tall brown haired man poked his head out of the door.

"Ooh, bit brisk for this time of year! Better dress up warm, Professor!" he headed back inside for a brief moment before fully exiting the box, wrapped in a long brown trench coat that reached to his ankles. Next to him stood a brown haired woman, her bright blue eyes contrasting with his brown ones. She pulled on a black trench coat, similar in style to his.

"It is just a bit, isn't it? Sea storm." The Doctor nodded.

"You can taste the salt."

"I can taste something else as well."

"Let's not go there." He winked at her playfully.

"I was only going to say that I can taste the smog of good old 21st century New York! C'mon then, are we going or what?" It was her turn to wink playfully at the Doctor. Stopping only to lock the door, they took off for the centre of the city.

OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

Ok, that's chapter one. Sorry it's really short, but I didn't want to make it sound like it was running on, you know? Hope you all like it!
