Natural selection, as it has operated in human history, favors not only the clever but the murderous.

"How-how did you do that?" Fluttershy squeaked.

"I have been this way for a while." You lie.

The words rattle around in her head and start to push away any doubts. Then she gets a grip of herself.

"No you haven't, you just turned into that-that-whatever that is." Fluttershy said nervously.

"Well, I guess I need to work on that." You say in a deep voice.

"The princess didn't tell me that you are intelligent." Fluttershy says, getting more curious about her new supposed friend.

"Well I am, what is your point here?"

"How did you get a pattern like that?" She asks as she walks around you, studying your body.

"How did you get those colors? It is essentially the same question. In fact I have questions to, where am I, where was I found, who brought me here, when do I get to leave?"

"On the outskirts of Ponyville, Canterlot, the royal guard, when you learn how to get along with ponies. And judging from your rudeness I would say you have a while to stay mister. Sorry." She squeaks at the last minute.

"You aren't really consistent are you? I'm going to take a guess and say that you don't have many friends."

"You're right." She sighs.

"I don't have any friends either, now I'm gonna go make some."

You walk to the door, but when you try to open it, you get launched across the room, your skin turns to scales instinctively, and you crush the table into wood chips.

"What was that!" You bellow as your head turns back into its original sate for a second.

Flutter shy squeaks in terror as she sees the teeth that are everywhere in your mouth.

"It was a spell that the princess put up to keep you here." She says so quietly that even you, with your acute hearing, could barely hear.

"It must come down." You order the yellow mare.

"But I don't know how." She squeaked again.

"It must come down!" You order again.

"I can't" She says again.

With that you start to change to your true form again. When the change is finished you are a few heads taller than the cowering pony. You lash out with your claws, your arm is knocked back, and you start spinning. In a blind fury, you turn into a whirlwind of eight inch fangs, three inch claws, and thick scales. In a few moment the forcefield was shredded into bits along with the wall.

"Goodbye sweetheart." You growl through your rage, and bound through the wall.

Remembering the bear outside the door, you look to it and leap. Your claws sink through the fur and flesh of the big black bear and he woke with a start. Before he could react though, you sink your teeth completely through his neck. The bear is dead within seconds and you start to rip chunks away from it and savor it as it slides down your throat. The fur is a bit nasty but other than that it is delicious. You start to realize that you lost control of yourself due to hunger as you start to wallow in the dead bear's blood. You stand up, look around, and pounce on a chicken, which is then eaten in a single bite. As you start looking for another meal, you see the same yellow pony giving you a strange stare. It makes you feel uncomfortable, but other than that it doesn't do much.

"What?" You say around the chicken in your mouth.

"WHY! Why would you do that! What is wrong with you! They didn't do anything to you! I could have you arrested!" She rampages.

"You and what army?" You say, still trying to swallow the chicken.

She jumped at you and twisted your neck. You are out cold for all of a second, and then you get back up. It is as if you don't have control of your own body as instinct kicks in. You unhinge your jaw all the way and let out an ear splitting roar. A tail starts to grow out from your spine and as it tapers off a massive bone blade grows out of the end, the scales that cover your body twist and morph into massive thorns, and your teeth start to drip with an acidic substance. Your tail cuts down a tree and uses it to take off the top layer of the small cottage. The hen house gets shredded by your claws and Fluttershy runs into what is left of her house. You bust the doorway into chunks of plaster and grab her by the tail. You start to spin her around, throw her into the air, and knock her, as luck would have it, in the direction of town with the flat of your new tail. It lashes back and forth, and the house turns into rubble around you. As you come to your senses, control comes back to your body, and the red retreats from the corners of your eyes.

"Well, I done screwed up." You say in a mock southern accent for no reason.

You gather together the pieces of rubble, make a small nest, start to take a nap, and wait for the guards to come and get you.

Fluttershy hurtled through the sky, and she could feel the boundaries of the air pushing on her from all sides. She knew what would happen now. She stopped suddenly and was flung, as misfortune would have it, straight through the door of the library. Twilight came rushing downstairs.

"What was that! Fluttershy are you okay?" She asked hurriedly as she helped her friend up.

"It was a horrible monster!" She sobbed, "It changed and messed with my head, then it killed some of the animals, I think it even destroyed my poor house!" The yellow mare bawled her eyes out.

"That's terrible! Spike, send a letter to the princesses and tell them to come here as soon as possible! Now why don't you tell me what it looked like."

Twilight began pulling books off of shelves, some old some new, others very ancient.

"It had really long fangs and *sniff* big claws. Its mouth was filled with teeth and, oh Twilight, it made the most horrible sound!" Fluttershy was having a hard time dealing with this. All of her shyness disappeared and she explained everything Twilight needed to know.

Twilight skimmed books as they floated in circles, and when she finally found a picture, she asked for confirmation. She got it and found out the horrors they were dealing with.

"It is called an... Wait that can't be right. I think it is called an elite changeling. It says here that they were bred in the hundreds during the ancient wars, and their natural instinct was to consume and destroy by any means. It also says that while they can change form they mainly use their changeling abilities to adapt to new situations on the battlefield. But apparently they have been extinct for about a thousand years."

"That explains why the princesses asked for my help then." The pink maned pegasus choked out.

"What! The princesses asked you to deal with it! I'll have to talk to them!"
