Getting a college roommate is random chance.
Sometimes you get lucky, and sometimes you get a pony.

Rainbow Dash enrolls at an Earth university.

Update: and then some other stuff happens.

Or perhaps Cheerilee is Batman?

Something I just couldn't get off my mind until I wrote it down. Be warned: the ponies in these battles really go off on each other. Almost exactly like it is in "Epic Rap Battles of History", except with less cursing. There's plenty of verbal bashing, though.

Vinyl Scratch is the DJ for most of these battles, and will be doing the all-caps commentary (except for the ones she's in, of course). OC tag because of slight self-insert.

I've heard that this story is better when read with someone else. You know, with each person doing one half of the rap battle?

...should there be a 'sex' tag, considering some of the stuff brought up in the rap battles?

Three new stallions show up in Ponyville. They all claim to be from a place called Earth, but they aren’t friends. Twilight must figure out how to keep them from killing each other, and somehow stay sane in the process.

This story is now complete, we hope you enjoy what was written and you can look forward to sequels for each of our respective characters in due time.

(please read entire description)
(News: first prelude 'Unreconciled' is being written for release before chapter 3)
After nine relatively peaceful years in Ponyville, Spike falls into hibernation and a protracted nightmare.
Upon awakening, the uncertain future of the World is thrust onto him by a message from the Great Teacher, Starswirl,whom may yet live.

The Royal Sisters are trapped in conflict with a Draconic entity capable of destroying the universe.
All the while, Spike and the Elements of Harmony each must seek out powers and wisdom rooted in the origins of the world.
They do this in hopes of overcoming a foe that roils the black and starry depths of the very heavens.

In their absence, the former CMC and the uprising youth of Ponyville grasp power in the midst of possible griffin invasions from the Avian continent.

Being a changeling has its benefits, but when a changeling leaves the nest to live a normal life away from the tyranny of the queen, how long can he keep his secret in a world where he is hated? How long can one pretend to be somepony they aren't?

"I'm Yah-Shee and he's Arrell, and it's our job to analyze their weapons, armour, and skills to find out who would win an Equestrian Death Battle."

This story takes the concept of Death Battle and carries it over into Equestria, pitting different ponies and other Equestrian creatures against each other in one-on-one fights to the death to see which is superior. Extensive research is done on both combatants to figure out who would win, and is presented as a written battle to be more entertaining.

Readers are asked to suggest possibilities for battles in the comments, or by messaging me. You are allowed to suggest OC characters, as long as they are from a story that is at least somewhat well-known.

"But for now, it's time for an Equestrian Death Battle!"

Twilight's curiosity pushes her to go where no bookworm has gone before: on dates. Dates with lots of unfamiliar (and not so unfamiliar) mares. It goes about as well as you'd expect.

A parody of dating websites in general, named after eHarmony.

I've successfully created the worst fanfic ever. It's beautiful. I took everything that everybody hates about fanfiction and put it into a fic in an attempt to elicit all of your hate.

Summary: A young man is telepoted to Equestria where he meets all of the ponies that he knows and loves.

Shipping. Shipping the never before shipped!
After the end of Season Two, the mane six enjoy a cruise and along the way meet six unusual partners...!

No OCs. The challenge is in shipping something not seen before, is it not?!
Don't bother checking the character list either. I won't spoil the identities there. Maybe when all the chapters are done and online. Maybe.
