The situation has gotten ... out of hand.

Twilight Sparkle had thought that she'd cured Fluttershy of the bat influence, but it soon transpires that she was mistaken; now with their friend at risk of serious injury or death every night, Twilight and the others must do everything they can to keep her safe while they search for a more permanent solution.

If one even exists.

For many years, citizens of Equestria have lived in peace and happiness, protected by the princesses and the bearers of Elements of Harmony; but soon, everything will change. This time there are no villains or unspeakable dangers; there's just war, hate, and ponies giving and taking lives. From the streets of Detrot to the Royal Palace in Canterlot, each pony will rise up against his fellow pony, and one of them will not rise up to see another day.

Also has a spin-off, called The Nest

Warning: Beware of spoilers in the comments! The story contains swearing and gore.

Edit 4.03.2014: New version of the first chapter, fixed pacing and OOCness.

Fluttershy and Rainbow Dash find themselves in another world during the middle of a zombie apocalypse.

Surrounded by death, destruction, and those freaking alarms that are on every dang door, they must fight their way to safety through the infected hordes alongside four survivors that are thoroughly confused about why there are colorful, winged horses helping them, and how they could even wield machine guns without fingers.

An MLP/ Left 4 Dead 2 crossover.

Rarity's been getting busier and busier, leaving Sweetie bored and alone while at the boutique- that is, until she meets a creature...one that won't stop following her around...but, she's harmless...right? Right?

"Rangers Lead the Way", that's what people say. US Army Rangers have lead the way into every armed conflict the US has been in since it was formed. Now, Hunter Squad of the 75th Regiment have crash landed in Equestria.
In Ponyville, Twilight was preparing to study some spells Celestia had sent, when a large flying box flys over Ponyville towards the Everfree Forest. On the way to the crash site with her friends, 2 of the inhabitants of that box save them from a manticore.

Constructive Criticism Welcome! Oh and any relation to anyone living or dead is completely coincidental. However, if it is someone in a book, movie or video game it's because I couldn't come up with something

Octavia Philamonica has always had a nice, quiet life in Canterlot. After getting attacked and gravely injured by unnatural beings, a dark figure comes to her rescue, but there was a catch. She was warned, but she took it anyways. Now the calm, collected Octaiva is now a Vampony and works for a secret organization ran by the princess of the night made to track and kill dangerous monsters along side other Vamponies and Ponies.

As she follows around her master, a one Fluttershy, she slowly learns how to give up her old Pony ways and to embrace her new, darker powers as a Vampony.

Vinyl Scratch and Lyra Heartstrings are vampires, creatures of the night whose civilization has lived in humanity's shadow for thousands of years. They are self-sufficient and prideful, only venturing out of their hidden cities to replenish their stock of blood. But ties to past lives are not so easily severed.

When Lyra catches wind of supernatural happenings in her hometown of Canterlot, she and Vinyl take it upon themselves to investigate the cause.

It was supposed to go off without a hitch. It was a simple rocket thruster test. But of course, even an evil genius can't prepare for everything. So when John Steele sabotaged the Earthquake Beam satellite during the test firing of the doomsday rocket's thrusters, it exploded, taking Alexis and her entire island to another world. A world that didn't know her. One that would be perfect to try again on. One just ripe for the picking. Alexis will still get her adoration and glamor that she desires, and there's nothing anyone can do to stop her!

When peace loving equines declare war against humanity, they get more than they bargained for as large formations of bombers fly across the Equestrian skies; easily flying through the shield the ponies had constructed around there "great" country and decimating their cities and towns.

One-shot, Anti-TCB story so if you don't like reading ponies getting blown up by 750 pound bombs this isn't the story for you.

Magic pervades the land of Equestria, aiding it’s inhabitants. Pegasus ponies are able to soar the skies with great speeds, moving the clouds and controlling the weather. Earth Ponies are more down to earth, having a natural connection to the land, making them the green hooves of the world with an enhanced strength capacity. Unicorns have direct control of the magic pervading Equestria, and it channels through their horns, making them better organized and able to do bigger tasks. Alicorns, who have the abilities of all three races, and use them to their fullest ability. No other species have ever been affected by this magic however, so only the pony races are affected, making many other species jealous of the ponies magic.

Everypony knows this, along with every other species on the planet. But what happens when a member of a brand new species comes to Equestria, and is also affected by this field. This new species isn’t affected like the Pegasi, Earth Ponies, the Unicorns, or even the Alicorns. This new species has survived for 200,000 years, using their greatest talent…

Their Minds.
