An MLP/Warhammer 40K Crossover

The Iron Warriors 38th Company has landed in Equestria, entrenching themselves like a barbed hook. They hunt the aliens of the Tau Empire, intent on destruction and pillage.
A small squad is dispatched on a reconnaissance mission, only to find that there is intelligent life on this world besides the feuding space-farers.
Will these improbably adorable and friendly equine aliens turn the damned warriors of Chaos from their blood-soaked path, cleansing them of their dark legacy with the magic of friendship and harmony?

No.
No, that isn't happening.
EXPLOSIONS!!

Bon Bon had honestly thought her life as a secret Agent wouldn't come back to haunt her. But, when the Bug Bear returned, she became worried. She meets with Celestia after the wedding, asking if there is anything she should be concerned about.

What Celestia tells her, shocks her to the core. She has a daughter, a clone created from her own DNA from her Agent days on the off-hoof chance she would need replacing. When the agency dissolved, the clone was given to a family, Celestia not knowing Bon Bon hadn't known the clone was still alive or whether or not she'd wanted to keep her as her own daughter.

Now, Bon Bon must find a way to break it to the filly that her life has been a lie. She isn't the pony she thought she was and her family are, tehcnially speaking, not her family.

Motherhood was never said to be easy. Well, when your daughter's a clone of yourself and has lived all her life unaware, it's even harder.

An idea that popped right into my head after a comment Black Gryph0n made during the Bronies React 100th Episode.

Follow Speaker and his changeling brothers and sisters who, after the events of Canterlot, took it upon themselves to find a new queen. They found a portal in a deep cave and went through it, questionable circumstances aside. Now they find themselves in a world full of humans, and with a new queen!

Meet Catherine and her family as they cope with a gaggle of shape-shifting creatures who really do just want to fit in and be loved.

The problem is, Catherine's parents are not very keen on their daughter chosen to be the new Queen of the Changelings.

And the cat has gone missing.

The story that inspired the two short stories that lead up to this one!

FimFic Authors are In Your Bed by Admiral Biscuit

Which two stories, you ask?

Link to Estee's short story is here.

Update: The story is edited into a proper read without many of the horrors I originally put into it. Enjoy the ride!

Deciding he could be given another chance, Luna and Celestia come to an agreement to release the Chaotic God from his rocky imprisonment, locking his powers with a powerful spell. Magicless and with a chance at redemption, Discord's ways seem less chaotic than ever.

He does cause a lot of chaos though, to the faithful student of Celestia, who had eagerly taken over the task of watching over and teaching Discord by giving him a home under her own roof, in the process hoping to learn more about his species, powers and motives but surprisingly learning much more about both himself and her head... Which puts her in pretty amusing situations most of the time.

An adventure of a silly one sided (???) love and a look into the heart of Twilight Sparkle.

20-year-old Ryan Burbank is living with his girlfriend in their woodland home when he is struck by a mysterious infection seemingly out of nowhere. To everyone's horror, his sickness spreads quickly throughout his body, shutting him down one piece at a time. The doctors are at a loss of what to do about this new form of bacteria. Ryan and his loved ones choose to keep fighting until either a cure can be discovered...or the pain becomes too much.
At the height of his suffering, he discovers a happy little show while watching television in his hospital room. The bright colors and happy attitudes of the cartoon equines provide him with a much-needed escape from the daily pain of being killed from the inside.
Eventually, the pain becomes too much and he decides it would be better to go out surrounded by his family, in the embrace of those who kept him company throughout his short life. Just as he starts to fade, his eyes wander to the screen of the hospital room television and the cartoon ponies who adorn it. Something strange begins to occur...almost like the screen is pulling him in. Tunnel vision, maybe?
No, that can't be it...why can he hear his name being called by a very familiar voice? And why is she...crying? Who is this crying, familiar voice and why does she seem to know him?

SPOILERS IN THE COMMENTS

Rated "Teen" for language and the "Sex" tag is for all of the sexual humor and suggestive situations. If I decide to up the suggestive stuff in the future, I'll change the tags and rating to fit that change.

Cover by enamis.

When Rainbow Dash receives the verdict that her final grade is in jeopardy, she enlists the help of most eggheadiest person she knows.

Unfortunately, she encounters a problem. A naked problem.

A very naked problem.

A comedy of the nudist variety.

It brings me great pride to say that this fic inspired the Nudists and Nudity group. Go check it out for all your barebacked needs!

Rated "T" for trigonometry.
Sex tag is for lewd jokes and language, not sex scenes.

Coming straight out of FTL, Captain Amelia Finegold barely has time to blink as her ship, Cobalt Blue, crashes into an unknown vessel in deep-space. Struggling to get ahold of an unexpected situation, things take a turn for the bizarre when she finds out the other ship isn't driven by humans. Or even occupied by humans at all.

One moment, Twilight is asleep. The next, lights and alarms blare as she comes to grips with an unexpected emergency. Problems crop up one after the other. Irreparable damage, wounded ponies, and a new alien species?!

Set in an alternate universe where Equestria became a space-faring empire.

Small note: Some revisions have been made, thanks all!

Everypony enjoys myths and ponytales, even if they know such things aren't real. Alicorns fighting against a spirit of chaos? An ancient princess trapped in a library under a tree, waiting to be found? Quite enchanting and fantastic tales yes, but nonetheless as fictional as Daring Do and other such stories. At least, that's what Rarity used to think.

She doesn't anymore.

Dedicated to Annuska for being as amazing a writer as she is a friend.

The war ended. They were beaten back, their mothership destroyed, their command structure in ruins. Lost ships and soldiers continued in vain, but thanks to XCOM, humanity won, and the world was saved. The Volunteer saw to that - everything changed because of one man.

And then suddenly, everything changed again. Only this time, it's not a man's doing - it's a mare's.

Proofreading by the aweome Setokaiva, entirely without me asking!
Tagged Dark and rated Teen: Gore, because there is going to be some blood shed by the end of this.

This story is a sequel to The Eagle Has Landed

When President Nixon orders, you obey. And now that he wants Luna on the LM and heading home, how is Neil ever going to convince her to follow?
But it doesn't even get that far, as an innocent mistake endangers the mission.
And even as the mission is endangered, tensions are rising back on Earth. While the drama plays out in Mission Control, just what is going on behind the Iron Curtain?
No one knows, but it's certainly not conducive to Apollo 11's welfare.

Sequel here.
