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)

Spartan-B312 A.K.A Noble six. The unsung hero and the only other Soldier designated as 'Hyper-lethal' of the Human-Covenant War. Were it not for her actions on Reach, the events that lead to victory over the Covenant and Flood would never have happened.

But that victory had a cost heavy price with Noble team dead and Six left on Reach as the Pillar of Autumn made for orbit.

Alone against the Covenant she was doomed. But she wasn't going to go down without a fight.

For three whole days, she fought. For three whole nights, she struggled against the full might of the Covenant on Reach. And on the third and final day, she fell.

Exhausted, battered, and beaten she was finally overwhelmed and presumably killed from what the helmet cam footage shows, the only thing remaining of the Spartan after the glassing of Reach was a broken helmet. But even after that, there is one constant that is never broken.

Spartans never die...They just go missing in action.

Now armed with a new equine body and armor to boot in a barren wasteland resembling the one she had just left behind, Six's Journey hasn't ended yet.

I-I have no words to express how happy this makes me

Halo: Reach Crossover (And yes my Noble Six is female)

Character tags shall be added as the story progresses

Spartan Adam-D014 was a lone wolf assigned to the UNSC Lightning. What was supposed to be a routine mission ended up with the frigate being ejected from slipspace unexpectedly, and with Adam landing on a strange planet inhabited by colorful, friendly equines. But something's not quite right... Adam's turning up in Equestria was more than mere coincidence, and Adam is determined to find out just what is going on.

Enjoy!

It's the year 2559. The UNSC barely managed to fight off the hordes of the Covenant. That victory came at a hefty price. With the war over and the rebuilding process beginning, the UNSC Tuscany is sent out to investigate potential new worlds to colonize. It's crew and captain are in for a surprise when a gravitational anomaly turns into a tense situation where cooler heads must prevail.

The discovery of a tiny extraterrestrial object within our own solar system makes a strangely equine alien race aware that the Earth is inhabited by an intelligent species, and they're on their way to come visit.

But since space is a really, really, really big place, they aren't going to get here for about a thousand years. They do have FTL communication, though, so while we wait maybe we'd like to be pen pals...

A crossover between the original Metal Gear Solid and My Little Pony: Friendship is Magic.

Whilst facing the legendary psychic Psycho Mantis in Shadow Moses, Solid Snake finds Mantis using a strange psychic power
to seemingly transport him to another universe, completely different from his. What's happened to Mantis? Why are there brightly coloured ponies everywhere? Is this all real, or is it just in Snake's head? And how will Snake get back to Shadow Moses and complete his mission?!

Rated Teen for some mild violence and swearing.

It's been a year now since Twilight vanished after attempting a sonic rainboom. She's spent her time fighting in WWII alongside her brothers in arms. Now, after a bad jump, she finds herself back in Equestria. After a well deserved rest, a nice, warm bath, and the most unusual breakfast, she begins to tell her story.

Isolated from her friends and taken prisoner in the middle of a war, Twilight must deal with the very real dangers of being percieved as an enemy as well as the nightmares of her arrival on 'Earth'. Can she overcome her own fears and the fears of her captors? Will the wayward unicorn's assistance be a boon or a curse to the 'humans?' Most importantly, will she ever find her way home?

"In short, it's a story of friendship and plasma rifles, with the emphasis on the friendship. The characters are well written, the XCOM setting is fleshed out very well, and the story is compelling. If you love XCOM, you'll love the story, but even if you've never heard of it, it's more than worth giving the first 3 chapters a read.

There's excellent action later on, but the real strength lies in the collision between the friendly and naive world of Twilight Sparkle and the desperate world of humans fighting a losing war for survival and willing to do anything to turn the tide."

Ponyville, Equestria. Population 5000.

Fallow Meadows, Indiana. Population 8000.

Two towns, two species, two worlds.

But worlds will collide when both are hit by mysterious storms that transport them to a third world unknown to either. Trapped in a place hostile to them both, can human and pony learn to work together? Well, yeah, the story wouldn't be called Unity otherwise.

The real question is what happens when it turns out that they are not alone...

Something has happened and Twilight finds herself in a strange and dark new world. The Bipeds here have strange magic, advanced technology, and a lot of problems. She needs a few friends, and they just might need her. WORM crossover. Deadpan29 has created some great supplementary material that is canon to the story.
