(I got this idea from Nightmare in Silver)

Adrenaline coursed through your veins as you clutch your head with both hands. A piercing screech was echoing through the walls of your mind, and you tried oh so desperately to make it stop. You tried everything, from meditating to almost punching the wall, but it wouldn't stop. It was ever going, as the galaxy and time itself (which apparently stops so...XD). The noise continued to get louder, and your thoughts turned to nothing. A numbness spread across your torso, to your legs, all the way to your toes, and then to the top of your head. You felt nothing. F/n L/n felt nothing. That was until the pain of the noise becomes unbearable. Agony was making your stomach churn like butter, and your heart to beat out of your chest. Blood rushed to your head, making your body temperature to increase. The pain! It's too much!! I CAN'T!! Biting hard on your lip, you let out a small whimper. Shaking, you couldn't control yourself for much longer. The noise was going to overtake you soon, you knew it. It was only a matter of time before the pain sets inside your mind, and then takes control. Hissing, you gave up fighting the noise. You finally gave in, which let a dark chuckle set into your mind. It was trying to control you. Well it wasn't an it, it was more of a who. Who would want to harm someone so gentle and loving like yourself. If you want it know, it's the Cybermen. How you may ask? Well it started when the Doctor thought it would be fun to take you, Clara, two of her wards Angie and Artie and him to an abandoned amusement park. Sure, it was great and all, but then a military operation started taking place. A man with a tall hat appeared, and Army officials thought that the Doctor was some sort of high ranked officer. Sure, army base with a abandoned amusement park what's new? But seriously, if you saw a Cyberman playing chess, you would be weirded out too. Especially if later you find out that the Cyberman was NOT inactive, but definitely alive. AND not only was the Cyberman alive, but he had a superficial intelligence that can upgrade anything. When I say anything, I mean anything. When you had taken a stroll around the amusement park to go help the Army officials, you heard screams of terror and ran to find the place where you left Angie and Artie to be empty. That was until you realized that a cybermite was watching your every move. So with your sonic screwdriver (after you caught the Cybermite of course) you followed a faint signal from the upgraded cold-blooded mammal. Upon your arrival, you saw Artie and Angie standing with a distant look on their faces. Scanning them with your screwdriver, you discovered that something was controlling them both. Your focus was then averted by the sound of footsteps coming your way. Thinking that it could be a Cyberman, you put a high frequency on your sonic and quickly turned. All you saw was the tall hatted human (later to be know as Webley) with a piece of artificial gear on his face. You quickly tell him to let the children go, but he told you that 'Children have a brain of full potential for the Cyber-Planner.' Webley then told you he had no longer needed the children because he had you, and you would be the perfect Cyber-Planner. On Webley's command, the Cybermites the attacked you from all sides. So, that what's brought you here to this moment. The Cyber-Planner was now in your head, and you desperately need to find a way to get it out. But what's the point in that? The Cyber-Planner asked you darkly. You suddenly found yourself in pain and then to realize that you were in your head, and the Cyber-Planner was in control of your body. A metal piece upgraded on your face to make you look even more ridiculous than you already do. Get out of my body! You screeched angrily at the CP (Cyber-Planner).

"Don't worry little N/n, I'll take care of you very nicely. Or will I?"

That last part of the CP's sentence didn't help your anxiety. You needed the Doctor's help. Growling angrily, you concentrated and found that you are now back in your body. Not for long~ The CP slyly said inside your mind. This went back and forth for a matter of minutes, until you both were looking at each other in a mind scape. The CP's upgrade made it easy to identify which one was evil, and which one was good. Glaring at the CP you growled at it.

(I'm going to put Bold for Cp's speech)

"Get out of my mind or else!" You stated rather annoyed and angry.

"You now this get's old after awhile. You and me, going back and forth. You know we aren't going to get anywhere."

"Oh? And how do we fix this problem, hm? Just keep talking about it I presume. You know that will get us nowhere." You reply with a sharp tongue.

"Now, Now. No need to get feisty." CP replied darkly, "How about this. We'll play a good game of Checkers (I know they play Chess, I just don't know HOW to play chess :/ ) and we'll show the score of who get the body."

"Okay, but if I win, you return Artie and Angie's minds back to normal. You will also leave me, my mind and my friends alone!" You state.

"Very well, but if I win, your friends are slaves to the Cybermen and you will never get your body back." CP replied mischievously.

~In the middle of the Game~

"You know that there is two things that can stop you temporarily." You said simply, moving your red king forward.

"Oh and what would that be?"

"Gold and Window Cleaner."

"Ha! You think you can stop me with Window Cleaner?! You must underestimate me."

"No, not window cleaner. Gold yes." 

You quickly take out a gold ticket that you got from the Good Webley. You quickly folded it into a flower, and stuck it behind your ear where part of the upgraded piece was. You could hear the CP's growling in the deepness of your mind, but you couldn't let that distract you. Folding up the Checkers board, you turned and told Artie and Angie to follow you. With the board game and two zombified children in your grasp, you had hardly anytime to notice the Doctor and Clara running up to you. 

"F/n! Where have you been?" The Doctor asked a bit worried.

"Not important, I need rope, and a table with an empty room." You quickly stated

"What happened to Angie and Artie?!" Clara asked shocked.

You facepalmed and heard the CP's growling getting louder. Glaring a bit a Clara, you sighed.

"There are Cybermen on this planet, but they aren't like anything I've seen before." You said sighing, "there is one artificial intelligence that controls the Cybermen though and it got to the children."

"How do you know about this artificial intelligence?" The Doctor asks straight-forward.

"It's in my head." You reply quickly, " and if I don't get tied up in a chair about to win this board game we become slaves forever. So please do me this favor, and tie me up!" You shouted.

***

The Doctor was never really keen on your idea, but went with it anyway because being a slave doesn't sound like fun. Artie and Angie wouldn't leave your side, and Clara became very worried. Looking down at the board game in front of you, you glanced sideways at the Doctor and Clara.

"You need to leave now." You demanded.

"What?! Why?!" Clara asked astounded.

"The artificial intelligence knows more about me, than I know myself. The more you stay in this room, the more of a threat you will be."

"No way! I'm not leaving."

"Hehehe. Suit yourself house-maid." Your words turned cold out of your mouth.

"What?" Clara asked in disbelief.

"Yes, I called you a house-maid. Now shut up you pathetic human, I'm trying TO WORK!" Cp yelled out of your lips again.

"F/n?" Clara asked again.

"Wrong!"

"What have you done with F/n?"

"I stored her away, until her turn of course." Cp's mischievous glance caught Clara's eye, "You should really hear what's going on in her funny head. All kinds of smart things you don't know about."

"Stop it." The Doctor said finally.

"Oh look. The Doctor speaks! Hehehe. Such a shame I'm going to have you as a slave, you just seem to valuable to waste."

"Who told you that?" The Doctor hissed.

"F/n thinks that. She thinks you're valuable, and that's why she sticks around you. You should really hear how things work in her brain when she's around you." Cp said grinning slyly.

"I don't want to know." He responded unevenly.

"But you're curious. I can see by the way you look at me. The glint in your eyes, the way you look like a steam engine ready to explode."

"Okay, that's enough." Clara said.

"Oh the impossible girl speaks. You know, F/n is frustrated by you. Apparently, you're a riddle wrapped around an enigma for her. You never stop, you never go, you keep reappearing in time again and again. It bothers her to no end that she can't crack you. Hehe." Cp's expression of her face turned from enjoyment to anger in a split second, "Now if you don't mind. I have slaves, a body, and whole galactic takeovers to win. So, GET OUT!"

Without a second thought, both of them left. That wasn't before the Doctor thought about what the CP said.

'She thinks you're valuable.'

(Hey my lions! So, what do you think about my first oneshot? Please reply with honest feed-back, and please no hate. :) Okay? Okay! Thanks again!
