This story is not easy to summarize.
Look, I don't want to give out any further details about the plot other than this: it's the South Park kids-Cartman, Kyle, Stan, Kenny, and Butters who travel to Equestria. And everything else happens in Equestria. It doesn't get taken into the outside world. I just don't want to give out any more spoilers without you reading it. But I will tell you that this story is thrilling, hilarious, fun-reading, meaningful, controversial at points, unconventional for MLP:FIM fanfics, and motivational.
Also, I cannot emphasize this enough: read the author's notes at the beginning of the first chapter, please. Without it, you would be completely lost and all like "WTF" the entire story, stop reading early, and miss the entire point of it. It's that important, like you probably would want to take a screenshot or smartphone pic of it. If you're for whatever reason a non-brony, you should only really need to read the first part.

There's a new life, and a new body, that awaits Rainbow Dash. She's no longer in Ponyville, but instead she finds herself living in Liberty City with Niko Bellic. Things are different, but there are somethings that never change. The need to help friends, standing up for yourself and your friends, and being the best are a few things that will never change.

One courier, one Queen, a simple delivery, and an incredible destiny. The Mojave Wasteland is a place filled with opportunity, danger, and adventure. For some, it is home. For others, a means for power. For the Courier? The birthplace of his legend.

Shortly after the Changeling Invasion, a human wakes up in Chrysalis' body in the middle of the Badlands. Alone, hurt, and starving, she tries to make sense of where she is and what happened. Unable to remember even her own name, she struggles with her identity as she faces the trials of being public enemy to a whole species.

Or, you know, she doesn't. Identity crises are overrated anyways.

Sergeant Gary "Roach" Sanderson and Lieutenant Simon "Ghost" Riley of Task Force 141 are revived in Equestria after being K.I.A. on the Russian-Georgian border. A massive combined evil force threatens to destroy the nation, and now the two must defend the ponies. Is there more to their arrival though?
Crossover with Call of Duty: Modern Warfare. Takes place between episodes 12 and 13 of Season 3.

This story was granted to me by JWR832, since he was unable to continue it. So, as one of his editors, I will be taking over. I will be consulting with him often, and he will be helping me change it to his liking. For my own purposes, all cursing (other than a few British words) will be omitted. I'm sorry if you don't like this, but it's just the way I write. Thank you all for supporting him, and I hope I can do almost as good as he did. This fic was just too good to die.

*Now with a sequel, To return home *

(Know I am planning on editing my earlier chapters with the help of two people I have met here)

Hello there, my name is Micah. Your typical Jewish fellow in Seattle. I only recently got back from a trip abroad to find a box in front of my apartment door. Apparently what was inside it were six My Little Pony figurines. Though, I soon find out they aren't figurines. They are the real thing. And, no, I got no freaking clue how they are here, nor why they are here. Only thing I am thinking of is this: Why am I tied up and on the ground of my own apartment?

And another thing that I wonder... Why won't they tell me why they are here?

Rated teen for some swearing and dark stuff in future chapters. Mostly the last two ones, which I admit are definitely darker and has violence and, well, some sensuality in it.

Gore tag added for the last chapter only. All other chapters are gore free, and even the last one is not heavy with it.

Takes place pre season three of the show.

Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.

Have you ever had a dream that just seemed so real, that it was impossible to say for certain that it was even a dream at all? A dream that, despite all of its impossibilities, seemed to re-write your entire perception of reality, re-writing your sense of what—and indeed, who—you are? Accepting change is hard enough as it is. But when you're a somebody who wakes up as a somepony, how do you cope with the impact such a drastic change has on your mind and body? With changes like these, it must surely just be a lucid dream—albeit a suspiciously accurate one—just brimming with potential and ripe for exploration. So you might as well suck it up and make the most of these distressingly…unusual circumstances, and seize this psychological adventure before you wake up and the dream ends.
After all, this couldn't possibly be real, so the dream must come to an end eventually…right?

Being a cowboy is usually very straightforward. Frank, however, finds himself in over his head when he meets a unicorn - a very whiny, needy unicorn with a compulsive need to be fabulous and an unexpected knack for gunslinging.

In a world where nothing comes easy and everything is incredibly dirty, a man and a pony are going to have to rely on each other to make it through.

Reality is a fickle thing, sometimes it just ignores the world of fiction while other times it comes down like a hammer on a nail. Let us go back to the Strange World of bipeds and of technology to see what Twilight and Spike did not see; how the world would react to their actions. How the world reacts to such actions that would remove the veil of safety and precedents... and how the government tries to cover it up.
This will include spoilers to Equestria Girls, in case the description didn't make it clear.
Rated Teen for general descriptions and references that may upset some.
