Nightmare Moon won. She defeated Celestia, broke the Elements, banished the sun. This all happened a very long time ago. So long ago, that she has had plenty of time to change her mind.

Of course, fixing our mistakes is never so simple, and never without consequences. Even with particularly potent help.

Applebloom just wanted to spend a day with her friends, crusading for her cutie mark. Instead, she found something even deeper and more troubling about herself. Turns out she's not even a member of the Apple Family by blood. In fact, she's not even truly native to Equestria! She's an alien! An alien robot no less!

Now Applebloom will have to deal with the reality of her origins and try to cope with them and her newfound abilities as she moves towards her future; a future that just might never come to be if her new foes have anything to say about it. Decepticons are, after all, a monstrous cabal.

Now, it's up to Applebloom to light Equestria's darkest hour.

A girl called Hannah gets sent to Equestria and has to help the mane six before nightmare moon takes over.

Starts at ep one, my first story so pls don't hate. Art from google.

A human wakes up in the everfree before the events of nightmare moon. Or adult Luna and Celestia. Oh, and he’s a bird. A magical bird, but still a bird.

An average but nerdy young man goes to an anime convention dressed as Ichigo from Bleach. He was missing only one thing from his costume, where a mysterious merchant sells him just the item he needed. The next thing he knew. He was in a new place with no way home. Met some of the locals and got possessed.

Trapped in stone for a thousand years and no memory prior to that convention. He finally breaks free and is loose upon Equestria once more, even stronger then before.

But this time, is he in control?

This is a Displaced story

Note that MLP does not exist on the main character's Earth.

Her attempt at a Sonic Rainboom. Failure. Crashes in the Everfree and lands next to the Castle of the Royal Pony Sisters. Well just fly out, you may say. But guess what; her wing is torn.

Dash loses consciousness under the impact, but lastly sees a predator of the night. Guess what, it had fangs. Dash is a goner.

She wakes up though. However, she was not set free unchanged. And her hostage pony is still with her.

* * *

A bloody gore story. You can guess the rest.

When Fluttershy went to bed, she was a normal mare. When she woke up, she could see numbers floating over everypony's heads. They were timers, each one counting down to some unknown event. Most ponies had timers that wouldn't end for years, some for many decades. But everypony had different numbers.

So why does Rainbow Dash's timer end in three hours?

Rainbow Dash knew from the start that she was the daughter of King Sombra. When they were in the Crystal Empire the first time, Rainbow had used shadow magic, powered by her strong wings, and moved around to inform Applejack about the Crystal Heart. Now, Twilight found out a few traces of dark magic Rainbow had left behind the first time. She immediately informed all the princesses and the mane 6 are in the Crystal Empire, hunting, unknowingly, for one of their own.

This is after Secrets and Pies but before Shadow Play.

This story is a sequel to Normal Life

Cause and effect. Opposite and equal reactions. If a butterfly... You know how it goes. The point is that your actions, large or small, have consequences. If they turn out good or bad is often not up to you. Especially when you live with the Princess.

But fear of the consequences is not a reason not to act when you need to.
