Title says it all. Time travelling shenanigans ensue.

For the small town of Ponyville, the eve of Nightmare Night will forever be seen and viewed as a tragedy and murderous event. Pinkie-Pie, the Party Pony of Ponyville, has been accused of murder by a Health Inspector working for a rival chain of bakery and sweet shops in Equestria. Even with a powerful defense, Pinkie-Pie was charged with one count of Murder, but fled Ponyville soon after, her friend Fluttershy honorably taking the fall for her escape and herself being imprisoned for being an Accomplice. Five years later, a Detective Pony, Mr.W.Quill, will learn and discover the mystery of Pinkie Pie's Dark Descent, and the grim, bloody trail that was left in its wake. How the story ends...only through hearing the tale will the Detective discover it. He is willing to unravel the truth behind a plot of sinister evil...and will learn what a Pink Mare had to do, to save herself, and a town under siege

This is the tale of a baker, who had everything...and a colt of Power took her friend away, destroyed her happiness, and accused her of a most atrocious crime...and in her sorrow...a new mare was born. Never Forget...NEVER...Forgive.

Stay Tuned for a sequel!!!

It had been about a month since the changeling incident in Canterlot. Everypony is on edge, because stray changelings keep popping up here and there, trying to blend in with the population. Everyone worries that one of their closest friends, or even their family, could not be who they appear to be. But what happens when a pony isn't really that pony...

...but they're not a changeling, either?

After a long day of work, Ditzy (Derpy) Doo wakes in the night to find that she is in the middle of the zombie apocalypse. Worst of all, the zombies arent even ponies! Instead, they are some strange type of two-legged creatures with hands. fortunately for her, she is found by four of these creatures that dont seem infected. But can they help her escape this nightmare? For that matter, can any of them escape the hell-hole of a city they find themselves in?

Part 1: Lyra's Pyro Predicament
Part 2: Twilight's Demoman Devastation
Part 3: King Sombra's Robotic Retaliation

When a mishap causes two para-dimensional weapons to colide with one another, RED Team's Pyro is sent flying from the Team Fortress 2 universe into the alternate universe of My Little Pony, where he is almost instantly discovered by Lyra, who shelters him in her home.

Having him hidden in her small townhouse isn't easy; keeping him from setting things on fire, teaching him that not every cart that passes by is cause for alarm, and that blue ponies are not something to be suspicious of.

However, with Nightmare Night soon approaching, Princess Luna feels that there may be something more sinister riding on the coat tails of Pyro's grand entrance; the first human to ever set foot in Equestria some thousand years ago...

The creak of metal echoed as a hellish choir in the room. Lyra sobbed, clutching the little communication device to her barrel, as though it were her life itself. "Please..." She whispered. "Anypony, I think-I think it's getting closer." ...A sickly, raspy breathing crested the doorway on the other side of her hiding spot. "Help..."

But not all of their specimen and objects are dangerous. They are varied, some help, some kill. Some are delicious. Some, are deadly.

And some are...well... Cute
