Sam wakes up in Equestria stark naked and with no clue how he got there. More problematically, he seems to be in somepony's home.

Teen for nudity and the awkward situations arising from said nudity.

A rewrite of Make Friends, or Die! by Sam Polson (which has since been taken down). I liked the premise, but Sam's English was spotty and Google Translate didn't help him much. Starts going in its own direction fairly quickly.

A strange occurrence left you stuck in Equestria. Awesome, right? But questions arose about the method of transportation. How did it happen? And what does it have to do with the unicorn Twilight Sparkle?
Along the way of finding answers you made new friends, discovered new things about yourself and the world you thought you had already figured out.
This is your tale.

There are three distinct moments of time. One is the present, a constant menagerie of ever-changing conditions, where all life live and act. Another is the future, full of uncertainty and possibility; in which speculation and imagination exists . Finally, there is the past, set, unchanging; from where remembrance and recollection occurs. To simplify: one can only hope for the future, live in the present, and recall the past.
But what if one could do the impossible? Something so unbelievable that it shouldn't even be feasible.......

To grab history by the reigns.

An object of unknown origins crash lands in the no-pony's land between Equestria and Gryphon territory. Princess Luna and Twilight Sparkle race to beat the Gryphons to the crash site, but discover more to the crash than they originally thought.

It has been several months since the disappearance of Twilight Sparkle..

One night, after watching her sister raise the Moon and set the heavens alight, Princess Celestia begins to bed down for the night, only to be interrupted by portal forming in her room. From out of the portal comes none other than Twilight Sparkle, garbed in strange armor.

Princess Celestia, along with Luna, Cadence, and Shining Armor, are overjoyed by the Element of Magic's return, but are justifiably curious as to where she had been and what she had been doing. And so, Twilight begins her tale. A tale of survival against impossible odds. A tale of a people fighting for the most basic right of all sentient beings. The right to exist.

Going up to the roof for some fresh air after pulling and all-nighter, our "hero" makes the mistake of closing his eyes for a bit.
When he opens them again, he is no longer on the rooftop in Copenhagen he was expecting to be on... no he's somewhere very different, and extremely unfamiliar.
How will he react? How will the ponies react? Nothing is certain, except for one thing...

He never asked for this.

This story takes place about 8'ish years after the second season of MLP:FiM, the language of Equestria does not match any earth languages (that the main character knows of at least), and the human in question knows nothing of these ponies or the world of Equestria.
He emerges into Equestria on the roof of a building in Manehattan, not the Everfree, not Ponyville and certainly not one of the princesses' bedrooms in Canterlot Castle.

Oh! Spoilers in the comments and all that jazz, not gonna go into a whole spiel about it.

The Princesses find an alien creature barely clinging to life at the scene of a terrifying crash. Can the Combined Power of the Elements of Harmony save it, or more importantly, should they save it? Will the arrival of this strange creature tear Equestria apart?

The Lone Wanderer has been known as the man who shouldered the nightmares of every man, woman and child in the wasteland, so that they may live. But when the Wanderer was once again abducted by aliens, he found himself falling, quite literally, into a whole new wonderous world, untouched by the horrors of nuclear devastation.

He has been facing other people's nightmares constantly for almost a decade, it was high time he was allowed to wake up.

Meanwhile, the ponies of Equestria are baffled by a strange object that fell from the sky.

Fallout/FIM crossover. HiE. T for violence and some language.

Now with a TVTropes page!

A young man lost in the hilly embrace of a mountain sleeps the night away under a knot of tree roots. When he wakes he will find himself thrust into a strange new environment, the Everfree Forest. With only his pack and his experience as a Boy Scout to aid him, he must survive, make sense of his surroundings and with some luck, ultimately find his way home. What does one do after wandering beyond the edge of the map? And better yet...

What if you are not alone?

I have been reading fan fiction here for a while and wanted to give something back.
My first fiction ever so constructive criticism is welcome. Fair warning, it takes a while for me to write a chapter so expect gaps between updates.

[Hiatus notice: As of 10/1/2022 this fiction is on hiatus so I may focus on other projects and items, will resume at a later date.]

Rated teen for strong language
