Ditto, a changeling from the attack on Canterlot, is flung far from her home and lands in Ponyville. She crashes into Twilight's library, and finds it a nice place to stay, quiet, abandoned, and peaceful. Until, of course,Twilight returns from Canterlot and finds her.

How will Ditto survive? She is lost, hungry, and far from her swarm.

Will the ponies find it in their hearts to help this poor, injured creature?

For most of Applejack's life, she didn't know what she was. True, she understood who she was well enough.
But ponies don't change shapes, nor do they get strength from love.
Applejack never thought too hard on it... until the events of a certain wedding brought about some harsh realizations.
Now, with Equestria still reeling from the surprise attack, will Applejack manage to come to terms with what she is? Will she even be able to keep her secret safe?
For if the royal guards don't get her first, the conspirators in the shadows just might...

Comet takes his job too seriously. Angel doesn't take anything seriously.

Comet joined to protect kingdom and princess(es). Angel joined for adventure and danger.

Comet isn't interested in mares. Angel can't stop talking about stallions.

Comet is a pegasus. Angel is a bat pony.

Together, this unlikely duo goes through life as Royal Guards from basic training to fully fledged guardsponies. Who knows? Maybe they'll even start to get along.

Alone and far from home, Luna has sought out the changelings. Completely in their power Luna is entirely at the whim and mercy of the Queen of changelings, but what has prompted this strange encounter?

The Sangheili are a saurian species of fierce, proud, strong, agile, intelligent warriors and skilled combat tacticians. They are named after their home planet, Sanghelios, and are known to Humans as Elites, due to their adeptness and skill in combat. The Sangheili formed the military backbone of the Covenant for almost the entirety of its existence, they fear very little, and take great pride in an ancient, honor-laden code.

However, this group of Spec Ops Elites, Grunt, and Kig-Yar have crashed landed in Equestria by way of a slipspace drive being detonated in the middle of the ship they were heading to, the 'Glory Upon Salvation'.

Now they have to find a way off the planet and back into space so they can continue their journey to the Blessed Path... by dropping hot plasma on human worlds.
But will they want to, when something they revere tells them otherwise?

October, 2179. The USCSS Alhambra has discovered a distant planet amazingly rich in precious ores and minerals designated as "LV-1349."

Mining goes rather well for about a week or so.
Until the entire crew of the Alhambra vanishes.

With a massive payload worth billions waiting to be towed back, the United States Colonial Marines are called upon to investigate the missing crew and bring the Alhambra back to Earth. Their orders also include avoiding the local equine populace as much as possible... but as we all know, sometimes even the best laid plans can go to waste.

Seeing as how some of you want me to write more, I'll get on it soon.

Sequel is now live!

Revenge. It has been the only thing on Chrysalis’s mind during the months of her exile. What should have been her greatest triumph turned out to be her ultimate downfall. After months of waiting, she has at last developed a plot to win back the support of the changelings and take over Equestria: Run a dating service.

Disguised as the lovely unicorn Cherub, she starts up her business, ready to reclaim what she had lost. However, she soon discovers that the dating world is not as simple as it appears. Realizing that she cannot do this alone, she is forced to seek help from the most unlikely of sources.

Chrysalis has been defeated, now Shining Armor and Cadance can be wed. Or can they?

...Well, no. It seems the bride objects to it. Is this Cadance a changeling too? No, that would make far too much sense...

From a concept by defender2222 comes a tale of love...really, really screwed up love.
