The slender one.

An: Sorry if things seem to be getting really confusing, but everything will become clear.

Twilight's eyes went wide when the voice started talking. It was a low raspy voice, filled with malice.  Twilight jumped up and started looking around frantically.

"W-who are you? Where are you?!" She was still looking for the source of the voice. But she didn't need to.

I'm behind you. The voice suddenly seeming to come from behind her made her jump. She turned around and there was the owner of the voice. It looked like Slenderman. It stood just as tall as Slenderman, and it's form was the same. There was an antenne on the right side of it's head, poking out of a messy brown mane. It's right eye was blood red and looked like it belonged to a huge bug, skin missing around it and a bit of blood coming from it. However, it's left eye looked normal, but smaller than her eyes, with a blood red iris. It's mouth was filled with large shark-like teeth and it's cheeks seemed torn and ripped apart, a black and red liquid slowly dripping from it's mouth. It's skin was a sick pale and at some places it seemed stretched out. It's long arms almost reached his knees (she had just studied a bit about humans so she knows what those spots are called, how twisted and broken they may seem). Just like Slenderman, it wore clothes. But they were dirty and torn at some places. It wore a black shirt, it's sleeves spread over it's arms. But at the place where normally the mouth would be, was now a huge tear in the shirt and where skin was supposed to be was a gaping mouth. It also wore brown pants, part of the pants torn and spread over it's legs, like he had a sudden growth and became to big for the pants. And instead of feet he had eagle-like claws, only bigger and made of flesh.

"W-what are y-you?" She managed to say to it. She tryed moving away from it but it followed. And now it was a bit more out of the shadow, she saw four long, black and thick spiderlegs protruding from it's back.

Call me Leech. But enough about me. I'm here to talk about YOU.

"W-what do you mean?" She kept backing up untill she bumped into a wall.

You, your friends and that pesky Doctor are messing up my plans. Do you have any idea how long it took me to get Slenderman and that spimple minded Rake here? Do you have any idea at all?! He sounded angry and it's eyes were almost oozing with rage. She figured it was an he because of the voice.

"So you brought them here!" She exclaimed angrily.

Yes, yes i did. And what are YOU going to about it? You're just a dumb little pony! I could kill you right here and now! Yessiree, right here, and right NOW! He raised one of his claws as if to swipe at her. She closed her eyes and braced for the blow. But instead of feeling a claw digging into her, she was lifted of the ground by the neck. When she opened her eyes she was looking into his eyes.

But I have better plans for you. Yessiree, better plans. And you're coming with me. He cackled madly when the door opened.

"Twilight are you ok.... Oh no. Not you." The Doctor stood there, eyes wide with terror.

Oh yes! Allons-y Doc! And before I forget, say hello to Lulu for me. And then he seemed to dissolve into thin air. And so did Twilight.

"No... I'm sorry Twilight. I was too late... again." After that The Doctor rushed towards the control panel and entered his next stop: Canterlot.

They reapeared in a dimly lit cave, spiders and other creatures scurrying away at their arrival.

Welcome to my little home, Twilight Sparkle. He had the grin of a madpony on his face.

"W-where are we?" She asked, scared of what was about to happen.

Somewhere in the Everfree Forest. But I think you should be more concerned about what I'm going to do. He said cassually. He walked past a huge glass container filled with the same black and red liquid that was coming from his mouth.

"O-okay. What are you going to with me?"

All I'm goin to tell you is that your brother isn't going to be happy. And neither will your friends or Celly.

"How do you know I have a brother?" She asked curiously.

I know a lot more than I let onto my dear. And I heard you talk about him with Doc.

"Oh. But... Wait, what is that?" They reached some kind of table. It looked like the operating table in a hospital, but this one was rusty and covered with runes.

This, is my operating table. But this one isn't for surgeries, although what I'm about to do is similair.

"You're going to cut me apart?!" Her pupils dilated at the thought of him cutting her limbs of.

Nah. She sighed with relief. I'm only going to cut your head of.

"What?!" She barely had time to react before she was slammed into the table. He locked her to the table and said some words she didn't understand, making all the runes glow. He brought a big and shiny razor blade to her throat.

Now stay calm and don't move, because this will hurt a lot and it will only hurt more if you move.

"N-no... Please..."

Sorry, but this is necesary. And with that being said, his grin now gone, he placed the razor blade against her neck and turned it on, Twilight's screams echoing through the cave.

Have some battle music!

Luna stood there, glaring at him with mad eyes. Just when she fired a blast of magic at him he teleported to a safe place for Blue Breeze to hide. He placed her down and gestured to her to stay put. He knew he wasn't going to be able to outrun the angry princess, so there was only one option left.

'*sigh* It seems I have to fight her. Let's hope I don't kill her.' He teleported back and was almost hit by another blast of magic. He sprinted towards her and tried to grab her, missing her by an inch, and getting bucked in the chest.

'And I thought Applejack bucked hard!' He quickly dodged another blast of magic before grabbing her by the tail, lifting her of the ground and smashing her into the ground. She groaned but used her magic to fling him into a tower, cracking the wall.

'She's good.' He got up and dusted of his suit while the night alicorn charged at him. 'But I'm better.' Just when she was about to hit him he sidestepped and gave her an elbow in the back. He quickly backed off to avoid getting bucked again. But instead of bucking him she fired at his left arm. It was a direct hit.

"MMMUUUAAANNNNN!!" His arm lay on the ground, twitching and turning before turning into dust. He fell onto his knees, cluthing the stump where his arm was supposed.

'She cut off my arm...' The princess walked towards him with a smug smile on her face.

'She cut off my arm.'

"Thou shall come with us." But he refused to move and started trembling.

'She cut off my arm!'

"Come."

'SHE CUT OFF MY ARM! SHE WILL PAY!' Black root-like tendrills shot out of the stump, forming into a new arm. The skin on his head started to tighten and at the place where once was his mouth the skin ripped, revealing a mouth almost the size of a beartrap. At the places where once his eyes dents appeared. Black tentacles shot out of his back, pointing at the princess.

"Ummm... Come please?" In response the tentacles wrapped around her, squeezing the air out her. She was about to use her magic but one of the tentacles wrapped around her horn, nearly breaking it. She quickly lost conciousness and he slammed her into the ground. And again. And again. And again. And...

"What the heck is going on?!"

An: I think I made this chapter a bit too dramatic. And like I said: everything will be made clear later on.
