Two thousand years after the return of Princess Luna, Equestria's technology and magic has advanced far enough that the once far off dream of faster than light travel is now a reality.

And that reality is the ES Harmony, the pride of its designer, Princess Twilight Sparkle, and Equestria's first FTL capable starship. It is due to make its maiden voyage to travel further than anypony before it.

And yet when they receive a distress call from origins unknown, this ship's maiden voyage will become one the crew will never forget.

(Not a strict crossover with Star Trek, but here Equestria Girls takes place in the Star Trek Universe)

This story is a sequel to Cadance and the Wedding Crashers

(A Warframe Fanfic... Duh.)

The shock-wave from decimating an entire army of shapeshifters ripples across Equis, leaders shut their doors, panic grows amidst the fear and uncertainty, chaos spreads...

All the while twisted things stir in the shadows, plotting, preparing... growing...

(featured as of Aug 30th... how?)
(MLP + Warframe crossover.)
(Technically HiE but more focus is given on the Warframe angle.)
(probably goes without saying but, will have major SPOILERS FOR SECOND DREAM/WAR WITHIN! go play those quests before reading anything warframe related ever again!)

After being left to die in the crystal caverns beneath Canterlot by Chrysalis and her minions, Cadence had almost given up hope completely. Until she found something... something in the dark. Something that just might save them all.

The greatest hero in the universe has arrived in Equestria, with only one thing to say...

Clem.

An absolutely insane Warframe crossover.

A Displaced Human in Equestria story. A high school boy and his friends go to comic-con, he gets a Pip-Boy, and then they have a heart attack. Our "Hero" makes a deal with a being of darkness to give them a second chance, and things go down hill from there.

Edit: I forgot to put the ratings. It's T, not E. Sorry for the mix up.

It has been said that nothing lived on the land of Equestria before the three pony tribes became one and settled there. It has also been said that ponies cultivated and created Equestria with their own hooves.

This is wrong.

Thousands of years after the cultivation of Equestria, Zachery a human soldier whose sole task is to protect the human race is allowed to take a leave of absence. It has been thousands of years since the last pony sighting and being in constant state of wartime is deemed too stressful for both the militants and civilians involved.
While this is happening, Twilight Sparkle an alicorn princess of Equestria unearths information on a lost race that lived in Equestia thousands of years ago. Unknowingly to the both her and Zachery, she slowly sets into motion the events that will cause the two species that had violently divided to once again meet. For better or for worse.

In the final days of her life, an exceptionally faithful student muses on the subject of her perfect and immortal mentor Applejack.

Now with Spanish translation by Spaniard Kiwi!

Here's the story of colt named Tech. Who was living a pretty 'normal' life. Well, normal for living with the Doctor. Until today. Today, he meets two of the doctor's deadliest enemies. The Daleks and the Cybermen have come to their next battlefield: Equestria! However, this war has a twist. A small group of specialist Daleks and Cybermen have made a small alliance to end this conflict once and for all. Will this alliance end the war, or will it end Equestria? Or will that one guy from the beginning stop the Cybermen and Daleks and send them on their way?

This is a crossover with Star Trek, taking place in late 2269 of the Prime timeline, during the fourth year of the five-year mission of the original television series. It's not a crossover with the movies made by J.J. Abrams. It is mid-season five or so for Friendship is Magic. it is my humble offering for the fiftieth anniversary of Star Trek, which debuted September 8, 1966.
