After an unknown accident Twilight Sparkle and Rainbow Dash awake to find themselves sharing the same body! Now they must struggle to hold themselves together as their world is turned upside down. How long can two ponies exist in a single mind? It’s a race against time as they search for answers before it’s too late. When all is said and done, you’ll never look at Twilight Dash the same way again.

When Twilight Sparkle slipped beneath the covers last night, everything had been fine. She had friends whom she loved, a teacher she adored, and a bright future ahead of her. But when she woke up, her blankets and quilts had been replaced by hospital gowns and padded restraints.

Everything is wrong and nothing makes sense; even her friends have changed. The doctors keep telling her that she is sick, that none of it was real and that it was all in her head. Yet she remembers a life far beyond the hospital walls. She couldn't have made it all up on her own. They must be lying… right?

The Doctor has had a good, long run through time and space with Ditzy Doo. But it is that time again for him to regenerate bodies. But this time, it seems... different...
What would happen if The Doctor regenerated... as a mare?

Music.

It's great, right? Gets your hooves movin', your heart pumpin', really makes you feel alive. I'd always heard, felt, lived, breathed music every day, every second of my life, and I'd never even thought about it.

At least, not until I agreed to save another dimension while blackout drunk, traveled there with my best friends, almost died (many times), fought horrible monsters, met an actual living god...

And, well, there's more than that, but I'm getting ahead of myself already. For now, perk your ears, listen up, and you'll hear a story that I'll never forget. The story of the Eternal Song.

Twilight gets drunk and ships Rainbow Dash with everything in the universe.

Rainbow Dash is not amused.

Braeburn Apple has always been raised in a conservative household, as a member of the Apple family.
Throughout his life, he's been taught what's 'wrong' and what's 'right', who he was allowed to love, and who he wasn't. Above all, he was told what to be, and how to be it.
When he meets a certain blue Pegasus stallion buying pies at Sweet Apple Acres while he just so happens to be staying there, he discovers feelings he never knew he had.
Unfortunately, they happen to be the same ones he was always taught to suppress.
Can Soarin convince him that it's not wrong to be in love, and that, sometimes, in order to be happy, you need to break out of your comfort zone?
A story about discovering who you are, and being that person, no matter what others tell you to be.

WARNING: M/M, SoarinxBraeburn Coltcuddling! Touches up on some serious social issues in the real world, but with ponies, and at least 20% cooler.

The wheel of time turns, as destiny and history clash together.

Fifty years into the future, Sunset Shimmer is Princess Twilight Sparkle's most faithful student. She is smart and eager, but doesn't always think things through. Her life had been perfect, right up to the End of the World.

With a ruined future, Sunset travels into the past to alter the course of history. With only her mentor's cryptic word to go on, Sunset and the Elements of Harmony must solve the riddle of the Dark Regalia and stop the mysterious Vesper Radiance from rising to power. But the further Sunset goes, the more she feels like she's been through it all before.

Is destiny set in stone, or can Sunset shape her own future? Only time will tell.

This story is a sequel to Better Living Through Science and Ponies

THIS STORY IS CURRENTLY BEING REWRITTEN. PLEASE READ:
I've decided to rewrite this entire story. Considering that I began this project with almost no creative writing experience, I was bound to make some pretty bad mistakes. The story flow is not well organized, and there is an unhealthy amount of redundancy and poor pacing, as well as some pretty important things that I should have included. I intend to address these issues to the best of my ability, but it will be a long and arduous task. This story means a lot to me, so I want it to be more than the mere amateur mediocrity that it resembles. So, give it a read if you want, but keep in mind that it will change. I recommend that you put this on your read later list in the meantime.

This is a Portal 2 crossover. If you haven't played Portal 2, please do that first. Then read the prequel if you haven't done that either.

After Chell finally escaped the confines of Aperture Science, a freak portal mishap down below transported her, along with the entire Enrichment Center, to the land of Equestria. Upon entering this world, she was transformed into a pony. In a strange body and in a strange land, Chell was fortunate enough to be accepted by the ponies of Ponyville, and she lived out a new life contently among the ponies.

But that peace was not to last, for GLaDOS took a particular interest in the ponies of Equestria, and after two weeks of preparation, she launched a surprise attack and kidnapped 300 ponies to serve as test subjects, including Chell's friends and the princesses themselves. Once GLaDOS had them, she subjected them psychological torture. To save her friends, Chell made her way into the one place she hoped never to see again. In doing so, she freed the ponies, defeated GLaDOS in battle, and helped bring about the destruction of the facility. Although this made Chell a hero, she paid a terrible price in that brutal fight.

Beaten, battered, and traumatized, Chell spent months recovering from her wounds. After returning home from the hospital, all she wants is to once again live a normal life in Ponyville, but to do that, she must first heal from her wounds, both physical and psychological.

At the same time, GLaDOS herself has survived Aperture's destruction. With nothing left but herself, she vows to get back to testing. Though she faces an uphill climb, she is determined to see her facility rebuilt and the testing resume, and will stop at nothing to achieve this.

Has a TV Tropes page (will need to be updated after rewrite)

The works that this fanfiction is based on are properties of Hasbro and Valve. I would like to thank Pen Stroke for writing the original story and Flyer for his assistance and advice.

Please note, this is an unofficial sequel. I have received permission from Pen Stroke, but it is not canon to the original. I hope you enjoy it, but keep in mind that this is a fan work (of a fan work), and Pen Stroke holds the rights to the original story.

This story is a sequel to The Rainbow's Surprise

On the day of Fluttershy and Rainbow Dash's wedding, Princess Celestia left Twilight a message saying that she should prepare herself if something happens. The next morning, Twilight awakens to find that all of Ponyville has succumb to a blinding fog. She must now travel a monster-filled town in search for her teacher and friends and try to return Ponyville back to the way it was.

Caramel comes home one day to find a pretty envelope on his bed. Inside is a letter from Braeburn...

This story is a bit of a metaphor. This is my attempt at stopping bullying for being homosexual and it highlights one or two of the problems that can arise.
