When Twilight Sparkle had the magical surge that cemented her place as Celestia's student, the amount of power she released not only hatched a baby Dragon, it brought forth something else. Something that shouldn't exist any more.
Something that has Celestia worried.

A fluffy puppy.

[Despite the gore tag it's rather light on that, and they have yet to make a lewd tag and there's a bit of that.]

Season two is live here, Season 2

It's been a year now since Twilight vanished after attempting a sonic rainboom. She's spent her time fighting in WWII alongside her brothers in arms. Now, after a bad jump, she finds herself back in Equestria. After a well deserved rest, a nice, warm bath, and the most unusual breakfast, she begins to tell her story.

Fighters live for their next battle. They fight until they taste the dirt of defeat. But that was never supposed to be a part of Twilight Sparkle's schedule. Once, she was a promising student for Unicorns everywhere, and now... She's a bar fighter.
She says she'll leave Ponyville one day and return to her life as an accomplished scholar. But her new "friends" at Knuckle Brick Corner have made that more difficult than it needed to be.
Now she'll either have to learn to fight or learn how to fight better. As Equestria's rising contender for the most skilled fighter. Starting at the bottom of the loser's bracket.

Every respectable Princess needs to develop a hobby. In the case of Twilight Sparkle, that hobby is computer games.

Warning! Contains harsh Twilight language.

When I lost my sight, I became a recluse. I hid away, staying in my own world instead of out in the one meant for those with sight. But when Princess Celestia had me move to Ponyville, I had to adjust to a new walk of life, again intended for those with sight. I guess I'm doing okay, thanks to a certain pegasus mare whose kindness and gentle voice got through to me where everyone else has failed.
Rating may be subject to change at later points in the story.

[The Gore tag is for the end of Act I and onward. Beware of possible spoilers in the comments.]

Within every one of us, even the best of us, there is an essence of Goodness, and an essence of Evil.

After a freak accident resulting in her mother falling into a coma, Twilight Sparkle put her magic studies aside to pursue medical science in an effort to save her. Eight years have passed, and Doctor Sparkle has successfully concocted the TS8 Formula, a potion that can separate the natures of goodness and evil that lurk within the hearts of us all.

All that remains is a small test to prove that both the Formula and such a separation are conclusive. Everything will be certainly fine . . . right?

(AN: Takes place shortly after "Too Many Pinkie Pies", but before the "Twilicorn era".)

Based on Jekyll and Hyde: The Musical

Act I pre-read/proofread by TechnoFlare, Sixkiller5, and Crystalatrix

When Twilight first began her experiments in trying to figure out better ways to access the Aether, the realm of magic and souls just outside their physical realm, she did not expect to make significant progress. After all, pony kind has been trying to find out the answer to that line of thinking for centuries.

When she felt herself connect to the other realm Twilight accidentally manipulated its energies in a different sort of way. The Aether bent to her will much easier than before. Getting just a bit too excited, Twilight played with the Aether a tad too freely and the reality-bending powers of the outer realm sucked her into its bottomless depths.

Fortunately Twilight was able to direct herself back to the material realm using the closest, and brightest, soul she could find as an anchor. And the second she looked up at the skull of the skeleton sitting on top of a golden throne, she knew life was about to get more... interesting.

(A crossover with "If the Emperor had a Text-to-Speech Device")

This story is a sequel to Changeling Courtship Rituals

Queen Chrysalis attacked Canterlot, brainwashed Twilight Sparkle's brother, kidnapped her former foalsitter, defeated her mentor in combat, and conquered her kingdom. She kidnapped the sisters of Twilight's friends, turned them against one another, and tried to drain all of Twilight's magic. Queen Chrysalis has, at every opportunity, done her very best to utterly destroy Twilight Sparkle's life.

For some reason, this has not caused the pony to fall in love with her.

However, due to Twilight's misunderstanding of changeling customs, it does mean they are now married. Twilight eventually managed to tell the Queen the truth, but she forgot that whether it's a kingdom or a heart, changelings conquer.

And since the changeling way of conquest didn't work, Chrysalis is determined to try the pony way. The only problem is, of course, she has no idea what that is. But she knows someone who does: Princess Cadance.

Now, with the absolutely sincere help of her mortal enemy, the pony she once locked in the caves beneath Canterlot while trying to steal her husband on their very wedding day, Queen Chrysalis is going to woo the sister-in-law of that very pony.

Surely this is the most perfect plan ever devised.

Takes place roughly after season five (so Starlight Glimmer is running around occasionally)

Canterlot... For centuries, Canterlot was the shining gem of Equestria, the pinnacle of pony society. Now, it’s a reminder, a bleak and monolithic warning to the world. 

Changed by the chemical and technological poisons that plague the mountain, an abomination of nature, I wander the greatest disaster Equestria has ever seen. 

... I will escape eventually, and when I do, I hope my friends still see me as Twilight Sparkle, and not the monster that hides among the ruins.
