The slender one.

Chapter three.

Twilight had just sent a letter to Princess Celestia about what Applebloom calls, the Slenderman, when she heard a Manticore roar. But it sounded like it was in horrible pain. She turned around to look at the Slenderman, and he was looking back at her.

'How does he know where I am? He doesn't have a nose, mouth or eyes! What is he?'She started looking around to see if she had a book about him. She took out a few books about mythological creatures and a few about creatures in general. She also took out a book about Human myths.

'It's unlikely that I'll find anything about him in this book, but it's worth a try. I'll just start reading this one to be sure.' She checked the index and her eyes went wide in surprise. 'There it is! Chapter 49, page 576!' She went to page 576 and found a picture of him, with a description, and listed facts.

The Slenderman.

Description.

Slender Man, is a mythical creature often depicted as a tall, thin figure wearing a black suit and a blank face. According to the legend, he can stretch or shorten his arms at will, and has tentacle-like appendages protruding from his back. Depending on the interpretations of the myth, the creature can cause memory loss, insomnia, paranoia, coughing fits (nicknamed “slendersickness”), photograph/video distortions and can teleport at will.

It's victims.

It's victims are mostly children but it kills adults from time to time too. People who are being followed or stalked by him have nightmares about him before he kills them. Almost all of his victim's bodies dissapear but some of them have been found. The bodies had straight and clean wounds or the bodies were impaled. Some people who had recovered the bodies, had told others that they'd heard distant giggling. He always stalks his victims before killing them.

Origin.

Unknown. Some say he was once a normal human but those are just rumors.

Extra facts.

People have rumored they've heard a song playing around areas that victims were found in.

'Looks like I have to be careful around him.' She looked behind her to make sure he was still in his cage. Her jaw hit the floor when she saw the Slenderman reading books from the library.

"How did you get those books?!"

He took out paper and pen and started writing something. He turned the paper towards her. It said: "You really should focus less on the book and more on your spell."

She blushed in shame when she saw he was right. There were loads of weak spots in the spell and he could easily break free. She removed the weak spots and placed the books where they belonged. She looked back at him and saw his shoulders shake. She was sure  that he was laughing at her.

She looked at the book again but sadly it contained no more info about him. "Well, at least I know a bit more about you now." She suddenly heard humming coming from the Slenderman.

"That song... Is that song the book was talking about?" He nodded but kept humming and he sat down and moved his head back and forth with rhythm of the song he was humming. Suddenly she heard somepony knock on the door.

"I'm coming!" She walked towards the door. 'Spike is still too scared of the Slenderman to do anything, but he's still a baby Dragon so it's understandable.' She opened the door and in front of her was Doctor Whooves. "Oh, hello Doctor! Sorry, but I'm kind of busy."

"Let me guess, it's about the Slenderman?" He had a serious look on his face, which she didn't see often.

"How do you know that?" She looked at him in confusion.

"I know a lot more than you think. Now may I come in? I need some answers." He looked behind him as if he was being followed.

"O-okay." She let him in and he immediately walked towards the Slenderman.

"Why are you in this world? You should be in the human world!"

"How should I know? I've only been here for three weeks. One day I was walking around the forest, playing a game with the Slender Ghouls and the next thing I know is that I'm in some old castle and all of them were gone." He wrote.

"Slender Ghouls? You mean Humans and Ponies made of a dark smoking substance, straight clean wounds on different spots or holes in the body, white glowing eyes and a sick glowing grin, giggling madly and capable of killing a manticore in mere seconds?" This seemed to interest the Slenderman a lot.

"You know where they are?! Where?! I need to stop them from killing too many creatures!" The Slenderman had gotten up.

"They are in the forest. But why are you worried about them? You killed them!"

"It's not like I wanted too. Even though I had killed them, they were the only ones too keep me from going insane. They were the closest things to friends I had." His arms suddenly extended and he broke the spell. He started walking towards the door and broke it down.

Ponies everywhere noticed him and started screaming in horror. He kept walking towards the forest, ignoring everything else around him.

"Hey! Get back here!" Rainbow Dash tried to attack him but a black tentacle grabbed her. She saw it come out of his back and before she knew it he slammed her through a wall. "O-okay, I'll let you off this time."

Twilight, The Doctor and the others (except Pinkie) followed him from a fair distance, not wanting to be killed. The closer they got to the forest the louder the humming and the thicker the fog became.

Twilight noticed strange lights in the forest and insane giggling. "What is tha- AAAHHH!" One of the ghouls, a little boy missing the skin on the right side of his head and with a hole in it's chest, suddenly jumped in front of her while saying "Peek-a-boo!" and ran away laughing like crazy.

"What was that?" She asked shakily and she felt her heart pound in her throat. She looked around and saw that Fluttershy had fainted. Applejack picked her up and walked forwards.

"One of the ghouls. All of them are Slenderman's victims." The Doctor said. Twilight looked around and she saw them everywhere. She even saw a few ponies. One of them seemed familiar, she looked at it's cutie mark and her eyes went wide in shock. It was a lyre.

"Lyra!" Applejack was right, but Lyra was grinning like all the others and her throat had five straight wounds. "You... You killed Lyra!"

He nodded and picked up one of the ghouls. He threw her up and catched her, making her giggle like a child would when having fun.

"That's the girl I saw in the castle!" The girl looked at the Doctor and cocked her head.

"Lemme get this straight. Ya are saying he killed all of them?" Applejack stared at the Slenderman in horror and disbelief.

"That's right... he killed us all..." Applejack jumped when a raspy voice answered her question. She turned around and saw the most horrifying thing she had ever seen. It was a teenage male Human. His left eye was hanging outside his eye socket. His stomach was teared open and his insides were hanging out of a hole in his gut. A few of his ribs were sticking out of his chest. Parts of his hair were pulled out and the right half of his lower jaw was gone. His left arm was ripped of at the elbow and his right arm was missing chunks of meat. His left leg looked like it's joints were twisted and his right leg was stripped of it's skin. The only parts of clothes he had left were torn and ragged pants and a bloody shirt. Rainbow threw up at the sight of him, Applejack went green, Twilight looked horrified, Rarity was whiter than ever and the Doctor looked at him in confusion.

"Heh... Yeah... I know I look horrible... And truth to be told, I've been better... This is what happens if a group of ghouls catches you... Name's Mike... I don't remeber my last name anymore..." He grinned although it was hard to see.

"You seem to be more intelligent than the others. How is that possible?" The Doctor asked.

"Call me lucky... Call me unlucky... At least I don't feel pain anymore... And believe it or not, Slenderman is pretty good company when you're used to him..." He grinned again.

"He is?" Twilight asked.

"He is!" She jumped when she suddenly heard Lyra's voice behind her.

"Isn't it amazing!? I can't feel pain anymore, I can talk with humans, play games with them and all kinds of other stuff!" Her grin seemed to get even larger.

"You call this amazing!? Look at yourself! You look like a walking corpse!" Rainbow retorted.

"Okay I'll admit, that's one of the downsides, but what does it matter if everypony around me looks the same!"

"Grrrrr..." A Manticore Ghoul walked into sight. It was missing large chunks of meat but those were it's only visible wounds.

"Oh, shut it! I don't care if others are afraid of me! They made fun of me because of my hobby, but now I don't have to be around them anymore!" She seemed really happy about her new body and surroundings.

"You understand what he says?"

"Of course! Every ghoul understands what another ghoul says!" She giggled darkly.

"Okay, but why do you stay with him?"

"Because he's like our father! He cares for us all and he's really nice!"

"You all keep saying he's nice, but why did he almost kill Pinkie?" Twilight asked.

"Because he has these really sharp claws! He did it by accident!" Lyra's grin seemed to shrink.

"Yeah? I'd say he just wanted her dead." Rainbow said. All of the Ghouls suddenly turned towards the group of ponies.

"Nopony makes fun of Slenderman." They said in unison. They all started running towards them, their grins gone and eyes filled with bloodlust. "Join us! Become one of us!" They yelled.

"Everypony, here's a word of advice. RUN!" The Doctor yelled.
