Sweetie Belle gets curious about where babies come from, so she confronts Rarity about it.

After the disastrous invasion of Canterlot, an injured changeling wakes up near a small cottage and is quickly discovered by two of the last ponies she ever wanted to see. Now, with the help of her new "friends," she has to remain undetected in a town high on changeling hysteria that would not hesitate to throw her in the Canterlot dungeons should her true nature be revealed.

Simple, right?

Too bad she couldn't have picked a worse form to stay inconspicuous...

GLaDOS is free of Chell, free to continue testing, when she discovers a portal gun Wheatley tried to repair with duct tape. When the portal gun catastrophically fails, the enrichment center, GLaDOS, and Chell are literally dropped in the middle of Equestria. The mute test subject soon finds the world of ponies far more welcoming than the human world. But GLaDOS sees possibilities. Let the testing begin... for science.

It is the year 3070, and Mankind is once again at war. The battlefields of the future are dominated by fierce, robotic war machines known as BattleMechs, and under their auspice empires have risen and fell. Now with the worlds of the Inner Sphere once again facing the drums of war, two mercenary units have set off on their respective missions, their only tie a common ride upon the back of a JumpShip.

Yet when a cosmic accident causes a misjump, they find themselves thrown into a world that they cannot fathom: a world where magic is a force of nature, where mythical creatures live and thrive, and colorful ponies live protected under the aegis of their monarchs. New choices lie ahead, decisions must be made, and the inner character of Humankind will be put to the test when the question is asked: to conquer, or protect?

--------

It is the year 1023 after the ascension of Celestia and Luna to the dual thrones of Equestria, and Ponykind is at peace. With Luna cleansed and Discord sealed away even more thoroughly than before, all looks bright for the future of the colorful equines. With friendship and optimism, they face each day with hope and vigor.

Yet, when the heavens scream as a foreign object tears its way into their reality, the princesses and their subjects face a new threat that they cannot fathom: creatures and machines from a world of death and darkness, where magic is unheard of and the avarice of powerful men drive the engines of war to crush the innocent under their bootheels. Can they survive the coming of these coarse beings, and can they maintain the magic of friendship in the face of Man's Inhumanity?

A crossover with the Battletech universe, though this is an alternate BT timeline of my own devising. [WARNING: Fandom related material and fanboy rant to follow. Non-Battletech fans won't care, read at your own risk.]

Because **** the Word of Blake and their munch-tastic "armies from thin air" BS. Yes, I know the Clans were almost as bad, but at least they had some sort of justification in-universe. Wobbies? No. Just no. I don't care that it was 15 years, you don't go from "fringe group of mutually-antagonistic and argumentative sub-groups following various degrees of religious mania" to "WE ARE THE SPACE NAZIS ALL WILL BOW BEFORE US" like that.

So for BT fans, this is a 'verse where the Second Star League is still around, the Wobbies still had their temper tantrum though it was smaller and more in line with a bunch of religious fanatics. No stupid "knock everything down for ClickyTech" Wizkids/Fanpro approach, nor any "hey let's shove a bunch of cheesy Level 3 stuff at the players to make the game even more complicated" Catalyst Games stuff. This is just good ol' fashioned 'Mechs wailing on each other, only with ponies. Who will also be wailing on 'Mechs. GLORIOUS.

A Fallout: New Vegas/My Little Pony: Friendship is Magic crossover

The style alternates between omnipresent third-person and the Courier recounting his tale to... Well, take a guess.

After an incident with the heart of Liberty, Niko Bellic finds himself awake in an unusual hospital. He quickly learns that he is no longer in Liberty City. His rough, gravely world is about to be turned upside down.

Part 1: Lyra's Pyro Predicament
Part 2: Twilight's Demoman Devastation
Part 3: King Sombra's Robotic Retaliation

When a mishap causes two para-dimensional weapons to colide with one another, RED Team's Pyro is sent flying from the Team Fortress 2 universe into the alternate universe of My Little Pony, where he is almost instantly discovered by Lyra, who shelters him in her home.

Having him hidden in her small townhouse isn't easy; keeping him from setting things on fire, teaching him that not every cart that passes by is cause for alarm, and that blue ponies are not something to be suspicious of.

However, with Nightmare Night soon approaching, Princess Luna feels that there may be something more sinister riding on the coat tails of Pyro's grand entrance; the first human to ever set foot in Equestria some thousand years ago...

Twilight Sparkle believes she has perfected a process to allow Earth Ponies and Pegasi to teleport. Unfortunately, in the Land of Ooo, a bubblgum-haired princess is about to run a similar experiment. Will even all of the friendship in Equestria be enough to settle Finn down? Will Pinkie Pie ever get her doughnut? Perhaps along the way, everyone will learn that truly, friendship is ALGEBRAIC!
