Alright, my lovely readers, Dark!Doctor fic! And honestly, tell me you wouldn't want this? Face it, Dark!Doctor is a bad ass.

Darkness In My Heart

Rose stormed into the TARDIS in a blind fury, the Doctor not far behind her. She reached the center console and whipped around, sending her deadliest glare at the Time Lord.

"Fine! If you just can't appreciate anythin' I do, take me home!"

Everything seemed to freeze.

On the last planet they had visited, the two friends had gotten into an argument, which had only escalated as the traveled back to the TARDIS.

The Doctor stared at her, and Rose did her best not to quiver under the intensity of his gaze. Storming towards the console, the Doctor punched in coordinates faster and angrier than Rose had ever seen. They shuddered to a landing quite quickly, and the Doctor stormed over, opened the doors, and pointed out.

"Get. Out. Cardiff is there. Jack, Mickey, Martha, and the rest of Torchwood. Now get out." His voice was low and cold, and it cut through the air, made it to Rose's ears, and froze her soul. She stormed over, knocking into the Doctor purposefully, and strode out the doors. Rose spun around to make one last childish retort but found the doors slammed in her face and the fastest take off she'd ever seen the TARDIS take. Thinking he'd come crawling back in a day or two, she walked down to Torchwood.

The Universe quaked with fear.

The Doctor was too stubborn to go back, and darkness filled the gaping hole Rose left. His demeanor changed, becoming harsher, more deadly as the years passed. His appearance changed as well. In stead of being seen in a friendly brown pinstripe suit with a tan trench coat, he shifted, taking on a darker attire.

Even the TARDIS seemed to change, the warm ship becoming cold and doing whatever her pilot said. Planets and moons cried out with fear when they hear the sound of him landing.

Death and destruction was left in his wake, and he killed- oh yes he killed. Anyone who stood in his way was dead before they hit the ground. A hunting knife took place along side his now very rarely used sonic screwdriver.

Scars criss-crossed their way across his body- from both self-infliction and from others. His favorite and most infamous one was one that ran over his left eye, almost like a pirate. But he didn't wear and eye patch. The eye still worked, no point in putting himself at a weakness, he thought.

The word Doctor stopped meaning "healer" or "wise man", and began meaning "murderer", "assassin", and "executioner".

The warmness in his brown eyes faded- or, well darkened- becoming almost black. He stopped shaving, a beard growing across his face to almost double the coldness in his look.

Time passed and the Universe hid from the angry Time Lord, almost every planet knowing of him.

Except Earth.

Alien invasions now rarely happened on the small planet because the Time Lord wouldn't go near it. If the Time Lord wouldn't even set foot on it, the natives, people assumed, were even more terrifying. Which, of course, was wrong. The Doctor didn't go near Earth because of his past there. Time passed, and things barely changed. Stories were handed down for generations, knowing to fear the Time Lord.

5 Years Later

It was late at night in Cardiff, and the eight people of Torchwood Three sat, joking around while they ate pizza after a long day. The rarely -rarely- spoke about the Doctor now. Of course, they just assumed he went on and found another companion, not knowing the truth. But from the last time the Doctor had left, he had not returned to power up on the Rift.

Until now.

As Rose leaned forward to grab another slice of pizza, a sound penetrated her ear drums that froze her blood and stopped her cold. She slowly turned her head to look at Mickey, Martha, and Jack. They all stared back. And, almost simultaneously, the four sprung up and sprinted out of the Hub, followed by their bewildered co-workers. Sprinting, they manged to get in sight of the Rift before the Time Lord exited his ship. When the doors swung open, shock struck.

Though they were at a distance, they were close enough to make out the Doctor's features. He word a sharp, black suit, a black dress shirt, and a black tie, with black combat boots that had a knife in sheath attached to the side of each one. Of course, they couldn't see the knife he used most often, hidden in the same pocket as the dusty sonic. He strode out of the TARDIS, a careful mask of no emotions plastered across his face.

Rose took a step, and then another. She began unconsciously walking toward the dark Time Lord, who was now surveying the landscape with a murderous look in his eyes. Mickey, Martha, and Jack trailed behind her, the rest of the team just staying behind.

The Doctor finally noticed them, and a disgusted sneer crossed his features. The four humans attempting to approach him were making a mistake. Most ran screaming when they saw him, but not these idiotic four. He almost laughed. It had been a while since someone had attempted to approach him. So he stood, back turned and hands folded behind his back, waiting for them to approach.

Rose called out softly, almost afraid, "Doctor?" No answer. She called to him again. "Doctor?"

"You know, it's been a few centuries since someone tried to walk up and make conversation with me. Interesting."

The coldness still somehow surprised them, and the Doctor slowly turned to face them. Whatever emotions they still had for the Time Lord were hurt. The scar, the beard, the almost black eyes.

Rose took a few steps forward, reaching out. As soon as she was within a few feet of him, he snarled, hand shooting out and latching onto her wrist painfully. She cried out, and the rest of them began to move forward, including Tosh, Gwen, Ianto, and Owen. But before they could react, the Doctor had pulled out his hunting knife and was holding it to her neck. Mickey and Martha froze, but Jack did not. He continued walking forward while his team members pulled out their guns and aimed for the angered Time Lord.

"Doctor," Jack addressed him, "We all know you would never hurt Rose, now let her go."

The Doctor chuckled, which was a low sound that mad Rose wince even more. "You don't know me anymore, you freak." And faster than they could react, he threw Rose to the ground and stomped on her wrist. She screamed in pain as she felt the bone crack in two. While they were momentarily distracted, the Doctor ran forward and planted his knife in Jack's neck, killing the immortal for the moment.

That made the rest of them finally react. Mickey, Ianto, and Owen jumped on the Time Lord, knocking him to the ground. Mickey ripped the knife out of his grasp, along with the two others attached to his boots. He tossed them back, where Gwen leapt forward and grabbed them. The Doctor was growling inhumanly, attempting to fight the humans. He managed to punch Owen and knock him unconscious, but shortly after that, with a "Sorry, Boss." Mickey's fist collided with his face and blackness enfolded him.

Jack sprang back to life and got up quickly. He ran over to help Rose up, making sure to be careful of her now broken wrist. He realized they got lucky that it was late at night, or else innocent people might have gotten hurt. Tosh, Ianto, Mickey, and Gwen were dragging the unconscious and very heavy Time Lord back to the Hub as quickly as possible, not knowing when he'd wake up. Martha was waking Owen up, who now had a nasty broken nose.

The team finally all regrouped in the Hub. The Doctor was locked in a holding cell, Rose and Owen were being tended to by Martha, and the rest just kind of sat silently until Mickey broke it.

"Well. That was... different."

Jack barked out a laugh. "I'll say." He turned and saw Rose -with a cast on her broken right wrist- attempting to go down to the cells. "Where are you going?"

"I'm going to go talk to him! What do you think?"

"No, Rose! You saw him out there! That's not the Doctor anymore!" Jack pointed toward the door, voice low.

"Oh, is it not? Then why did he not kill me? There's still some of old him in there, I know it." Without another word, she stormed past Jack and went to the cells.

She walked over to the Doctor's cell. Both hands were cuffed to the wall, and he was still unconscious. Someone had removed his suit jacket, tie, and had rolled his shirt sleeves up. Rose gasped as she saw the multitude of battle scars crossing his arms. She turned and saw the items he had on him: three knives, a old looking sonic screwdriver, a pack of cigarettes, a lighter, and a small plastic skull.

Rose sat down in a chair across from his cell, and waited,

Oh come on, admit it. He's bad ass. You know you want it. Review, by the way. I have one day to complete this, and the more reviews the faster I type!
