Everything changes for Twilight Sparkle and her friends when a mysterious extraterrestrial ship crash lands in Equestria. When Twilight messes around in the ship's systems with her magic, she ends up transported to an alien world unlike anything she imagined: a box canyon in the middle of nowhere.

To get home, Twilight must enlist the help of the eccentric Red and Blue soldiers that live there... if she can get them to stop bickering first! Additionally, she finds herself being pursued by the enigmatic military agency known only as Project Freelancer. Back in Equestria, all is not well for Twilight's friends as forces involved with the crashed ship make themselves known. Reds, Blues and ponies will all have to work together to discover the mysterious connection between Equestria and Project Freelancer.

A crossover with Red vs Blue. Written with the intention for the story to be followable without having watched the series. (just don't expect to get all the references).

Now with editors! BradtheBrony and Rough_Draft.

I made a blog post explaining things. You should read it.

TvTropes Page.

"Hey, uh, Rick, what did you want me to, uh, write down here again?"

"Look, Morty, it's not that urp complicated, just, just write down a generic description of what we did."

"But Rick, we did a lot of things!"

"Then figurp it out, Morty. Christ, and here I thought you were getting at least a bit smarter. Just, write down something about, uh, 'Rick and Morty Get Stuff From Horse Land'. 'Morty and Rick and something something horse pun'. I dunno, something."

"I want to go back to the ponies..."

"Oh, I bet you would like that, huh, MMMorty? Go back to the girly dimension full of urp friendship and magic and all that. Look, just give it here, I'll, uh, just put it up as it is."

Now with coverart by some guy named Shadow Bolt

Princess Celestia had a good day. Luna had been going out more often and was becoming quite fond of nightclubs, her dear niece Cadance had formally announced her pregnancy—though, privately, Celestia felt she was too young to be a great aunt—and, of course, Twilight, her beloved former student, had taken on her first student and Celestia couldn't be prouder! Yes, it had been a good day.

Celestia Sol woke up much like she did every day the morning: sun waking her as it danced upon her eye lids. Wait, the sun? Celestia's eyes snapped open to reveal she was in Twilight's old room in the observatory. On the other side of the room was a smaller bed where a small dusky unicorn was drooling on her pillow.

Clearly, it must be Tuesday.

The following is a fanfiction of a fanfiction, a spin-off, a parody, please support the official release.

I was inspired to do this and I would hate to be red-bombed because I'm just a nerd who writes mediocre fics okay I'm stopping now

Dusk Shine was born a mare, actually, just a very selective mare that doesn't go out and completely expresses herself like a normal pony would.
This unofficial spin-off follows the brilliantly smart-mouthed Twilight Sparkle: an antisocial, awkward, unromantic bookworm who wants nothing more but to keep to herself and read.
However, that dream is pretty much like every character you're going to enjoy in this story because it was killed off when Twilight Sparkle is forced to leave her home in Canterlot and live in a smaller town named Ponyville to watch over the Summer Sun Celebration and to make friends.

How exactly is Twilight Sparkle supposed to make friends when everyone in Ponyville developes a crush on her?

The alternate story of if Starlight Glimmer was more committed to her beliefs, and had actually planned for the possibility of if she was discovered. This is the story of the possible future, starting from when everypony did not turn against her.
Now with Sequel: Foundations of Equality

Starlight Glimmer had a painful fall, but she is more than determined to finish what she started. The message of Equality needs to spread across Equestria, and she knows just the mares who can help her...no matter how many years it takes.

But she soon finds out that raising six fillies that still represent the Elements of Harmony is easier said than done.

This is a fic based on the Time Loop Files, the format of which was first codified by Innortal on fanfiction.net.
Here's a brief guide.
The basic idea is, one character (the Anchor, usually the main character of a fictional setting) is looping back to the very first moments of their parent series every time either they die or some kind of time limit expires. They of course end up monumentally stir crazy given enough time.
Eventually others start to loop as well.
The reset is not always perfect. Sometimes a loop's history will be different to the "prime" loop, or canonical plot.
"Crossover" or "Fusion" loops also occur, randomly. These can involve the home loopers having a guest, or the anchor for one universe spending time in another, or replacements of one character by another.
Vacation Loops are where the Anchor (or others) decide/s "buck it" and lets off steam by doing whatever comes to mind. There's little or no attempt to maintain the original timeline.

In addition, and particularly more recently, it should be known that this story has a collaborative element to it - people may submit loop ideas or loops, ideally at the Spacebattles thread (a link to the current version of which is on the Trope page), and they may become included.

There's two page image options, thanks to Filraen - the current page image has been edited by the original creator from this work of theirs.. The other one is here:
