Sequel: Left Behind: Sunny Disposition
Apparently it was scouted and is on EqD too

Nightmare Moon was meant to be released after a thousand years. A momentous occasion for her but terrifying for all the ponies on her day of freedom. She would get revenge on her sister and cover the world in darkness and shape everything to fit it.

That was the plan, at least. Instead, something went awry with the spell and she wasn't released when she was supposed to be. The mare-in-the-moon is brought into a world with stagnated technology, giant cities, and no sign of her sister or any of the other immortals. In fact, ponies don't seem terrified of her at all, and the stay within the core of her powers infused and changed the alicorn's body drastically.

The alicorn had no obstacles left! But...she was also a relic of the past. A past everyone seemed to have forgotten. A past she could no longer look upon.

“Tour America by Rail!” the sign said, and so Sweetsong does. Everything she needs for a journey fits into her saddlebags, and there are plenty of trains to choose from if she’s resourceful enough.

There’s nothing quite like having her hooves over the side of an empty gondola watching the world speed by, or looking at the stars overhead through the end bracing on a grain car. Sometimes box cars have their doors left open, and she knows how to jam them so they won’t close en route.

When she gets where the train takes her, she can live off the land or sing and play her guitar for money. When it’s time to move on? There’s always another train.

Once upon a time, Silver Spoon's life made sense. She had the right friends, the right house, and the right school for a young lady coming up in the world. Once upon a time, Silver Spoon lived amongst proud towers in a vibrant, bustling city that never slept.

Now she lives in Ponyville. Not so terrible once one gets used to it. Silver's learned to appreciate some ponies, harbor grudges for others, and tolerate the rest. But sometimes, she wonders if one pony in particular is as popular as she thought.

AU in where Twilight is a dragon but still is Princess Celestia's student. Twilight has a more logical head on her shoulders and takes her job as a caretaker to Spike more seriously than canon.

Waking up underneath the sea in the body of a pony mixed with a world war 2 warship was defiantly not how the newly named Yamato thought her morning would go. But since it did, she was going to find just what had brought her to this foreign land and fused her with a ship. Now she and three thousand members of her crew prowl the Oceans of Equis, intent on finding the rainbow light that seemingly brought her here. But Yamato's return has stirred up the ocean floor, and creatures never before seen rise from the Abyss to claim the oceans as theirs.

Will Yamato wield her cannons in defense of the innocent life of Equis? Or will she turn her 18' turrets on those who would prevent her from returning to her previous life? One things for sure, those who underestimate the might of Yamato will know the fury of greatest battleship ever built. (Kancolle Kantai Collection/MLP crossover/SI, not anthro)

Celebrating the 10 year anniversary of Past Sins! Thank you all so much for letting me and my stories be part of the community!

This story is a sequel to WHAT I'VE DONE

Equestria, the birthplace of not just the ponykind, but so many other races, as well. All these species are very much like our own, capable of both great compassion and great violence.

The story takes place during the events in the MLP: FiM episode, Princess Spike. Both MLP and Transformers are owned by Hasbro.

"The stars shall aid in her escape," it said.

It never said anything about a space bridge.

Megatron and his elite warriors had expected to teleport from the Oregon desert to Earth's moon. Instead they found themselves in pony bodies, stripped of most of their power, and forced to learn how to live like other organic life forms.

But Megatron has a plan. He will bide his time, learning about this new world and its new potential while his underlings try to find a way back to their home universe. If he can figure out a way to overthrow Celestia and conquer this land of ponies before then, so much the better.

This, of course, requires that his subordinates not act like idiots... and while he can count on Soundwave and Ravage, the same can't be said of Rumble, Frenzy, Laserbeak, Buzzsaw, Thundercracker or Skywarp.

And especially not Starscream.

A series of slice-of-life stories (with a little adventure) in which some of Ponyville's background ponies are more than... well... you know.

Sunset is quite unsure herself but with her friends alongside her, she's sure she will prevail.

"Doesn't this story sound familiar?..I know it does to me.."

Wow, I got featured again! Featured 6/27/2021

My story has now been judged for the contest and ranked so I’ve turned off comments now. I’m not interested in having to listen to more drama. This story will be continued with better explanation to it then this one-shot because I see it’s problems and I think it deserves better but that’s about it. Please respect my decision.
