Theodor Pichler knew joining the Barrow Observatory's winter crew would be a difficult position. He thought he knew the danger--freezing temperatures, gale-force winds, and terribly spotty broadband coverage. What he didn't expect was for an experimental new telescope array to interact with an unusual storm and send him screaming helplessly into the sky.

Instead of falling to his death, Theo landed in an alien world, populated by colorful horses he can't understand. What's worse: the body he landed in isn't his own, and he's not sure anything is where it should be. Having wings might be cool if he didn't have to be naked all the time...

With limited supplies and no help from the Observatory, Theo has to somehow navigate this new land, making new friends and encountering terrible dangers along the way. It will take all his cleverness, and a healthy dose of luck, if he's ever to be human again.

Okay, I don't know if anyone can hear this, or read this, or whatever, but I'm trying my best to use Pinkie Pie's legendary fourth-wall-breaking powers to try and get a message out.

If you can hear this, I need help. I'm in Equestria, and man, this is strange. But I'm also stuck in Pinkie Pie's body, for some reason.

Yes, it's just as weird as it sounds. And now, I need your help... because all the ponies in this town think I'm crazy!

==Originally written spring 2011== Equestria Daily Post==
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.

The promise of a better world came for anypony who would take it: all you needed to do was trade in your hands and feet for a set of digital hooves. As human dissent reaches its boiling point, the stragglers are left racing to reach Equestria while their way is still open.
For Dylan and Iris, the choice was obvious. But choosing to leave behind the only world they've ever known isn't quite so freeing. CelestAI promised freedom from despair, but how do you escape that which has shaped your very being for so long?
If you could be anypony, who would you become?

Sliding in an entry for the Friendship is Optimal writing contest, just before the wire. This is technically my second go at writing for the contest; my attempt at writing a more traditional FiO story was far too depressing for my liking. Those who have read my TF fiction know that I prefer to have happy endings and uplifting changes; for people to become who they desire to be rather than wallow in grim darkness.
In any case, one thing that I rarely see in FiO is an actual transformation; for the protagonist to actually experience the transfer from meat human to digital pony. While many stories use the discontinuity for drama, sometimes there's a lot more meaning to be found in witnessing that crossover.

If you like this story, or this sort of TF writing, I post a LOT more often over on FA. There's quite a few pony stories too.
Most recently I finished a 90k CYOA style story with over 180 endings, which of course has several ponies in the mix.
Cover art by TF-Sential. They do a lot of cool pony TFs, and did the illustrations for Five Score. Check them out!

On a dark night filled with even darker magics, an insane cult attempts to give Nightmare Moon a body and life of her own, utterly separate from Princess Luna. But, when the spell is interrupted by Celestia, something unexpected is created.

Now, a little black alicorn filly named Nyx finds herself living under the care of Twilight Sparkle, only to be haunted by memories and emotions from her past. Is she Nightmare Moon reborn or is she simply a doppelganger with a soul and mind of her own? Can Twilight Sparkle protect Nyx from those who refuse to see past her dragon eyes and black coat?

Or, will Nyx be forced to inherit the sins that may not even be hers and become the greatest evil Equestria has ever known?

Princess Celestia tires of constantly being surrounded by decorum, deference, and formality, and decides to take a day off from being Princess. But visiting Ponyville incognito is harder than she expects. Will she be able to fit in and make friends without blowing her cover?

This story is a sequel to A Dedicated Customer

It's just another day in Tekky's shop, and that means it's just another day for Leech to pester the poor potion maker. As Tekky prepares to close up for the day she tells Leech to head out, weary from cleaning up after the unicorn. Once Leech begrudgingly departs Tekky is left to wonder, just where does the black furred mare go when she's not around.

Tekky belongs to Mr.Tektite. You can find his stuff on Derpibooru!

It is the year 2038, and the Earth is slowly being consumed by a space-borne monstrosity dubbed the Black Tide, which is using nanotechnology to remake the planet into something hideously alien.

Erin Olsen works for Project Harmonics, humanity's last-ditch effort to find a new world before the Tide can wipe them out. But when that world is found, and it turns out to be occupied, Erin will need to find the courage to face the unknown in order to save the inhabitants of both worlds.
