MLP/Undertale crossover.
Not a PWNY-verse story.

Long ago, the Monsters and Humans fought a great war. The Monsters lost, and were sealed in the Underground. It would take the power of seven human souls to break the barrier that kept them imprisoned. They only had six. And so the Monsters waited and hoped, praying that another human would find their way to the Underground. Some thought the seventh soul would give their King the strength to break the barrier. Some dreamed of a human who would be their friend, and save them all...or had nightmares of one who would bring back the war.

...but nobody came.

...but somepony did.

Eons after the war, with no way to tell how much time had passed above, a tiny blue filly with wings and horn fell into the underground, calling for her Mama. None knew the poor creature's nature or origins...but her soul was powerful with magic, even more so than a human soul.

None can know what will come...of this little 'Woona'.

The planet of Chikyu is pretty odd, from an outsider perspective. There are anthromorphic sapients of every stripe and sort, the world president is a dog, its greatest warriors are alien monkeys, the average IQ (outside genius scientists or children) is somewhere below 50, and magic orbs raise the dead. How much difference would adding a pony that barely talks really make?
...quite a lot, apparently. Just ask Mr. Popo...if you dare.

A retelling of Sunset Shimmer's redemption, starting from the night of the Fall Formal and going through the events immediately following the Friendship Games.

Disclaimer: I own none of this source material. MLP: FIM and Equestria Girls belong to Hasbro, and I will not profit from this fanfic financially in any way.

Sex tag is only for brief discussions of sexuality and issues of modesty. There is no actual sexual content.

Author's notes: I've been working on this story for over a year. I'll admit it contains a lot of elements that appear commonly in other Sunset stories -- this is just my take on it. I'll try to give credit where credit is due -- although nearly every idea in this story occurred to me independently, others have actually published stories using many of them first.

The thrust of the story is to take material written for ages say 10-13 (i.e. the EQG movies/shorts/specials) and age it up to make it more dramatic and meaningful. Probably my favorite thing to write was the conversations that must have taken place, both in the human world and in Equestria, but that aren't depicted in any movie or book.

Full Disclosure: Sunset's friends play their usual crucial roles in her redemption and growth, but this is a Momlestia/Lunauntia story too. And there is no shipping. Romance isn't Sunset's priority as she crawls out of the darkness of her former life. Yet.

I had to add the AU tag after Forgotten Friendship came out. Up until then, this story was fairly canon-compatible. Now, it diverges a bit.

Good-natured warning: Feels. Lots of feels.

Spike figured things would be routine once he moved out; a job, home, relax, bed, rinse and repeat.

That is, until he somehow became the adopted older brother to a rambunctious group of little girls...all of them with a habit of calling him by 'Onii-chan', but that's not so bad, right? And he managed to get hold of a place big enough for them all.

Now if only he could figure out where these small technicolor horses keep coming from...

And why they're so cuddle hungry.

In the wake of the Fall Formal, Sunset Shimmer rediscover the family that she already has, and learns what it means to have friends and family. She also discovers the consequences of her actions and what those actions mean for two separate worlds.

Gore tag due to violent nightmare scenes.

This story is a sequel to Sirens of the Night

Things were looking up. Sunset Shimmer had friends, her popularity with her fellow students was on the rebound. She even had three new cousins! Then Anon-A-Miss struck. Can the Dazzlings prove Sunset's innocence before tragedy strikes?

After the Fall Formal Celestia adopted Sunset Shimmer. Now Luna has the chance to do the same for the Dazzlings.

I would lke to thank PrincessColumbia for writing a revised version of chapter 1. I hope you all enjoy it.

Chrysalis has heard rumors of a crystal mirror having the power to take ponies to other worlds, where they gain powers that put them on par with the likes of Princess Celestia or even the Spirit of Disharmony himself. She wishes to use the mirror for her own ends, so she can gain the power to finally have her revenge on the ponies that have taken everything from her and maybe regain her empire in the process. The world she finds, however, is the dark interior of a ship that is being overrun by dead creatures that will stop at nothing to kill her and the repair crew that came to fix the ship.

She must quickly get used to her new body while fighting the hordes of the dead, come to terms with all of the horrible decisions she has made over the years, and maybe see the light that the ponies talk about... provided that she, and her new companions, don't get killed first.

(Dead Space/ MLP Crossover)
(Part of the Universe 13 story series, though reading the other stories is not required)

Sunset Shimmer fled from Equestria in search of the destiny that Celestia sought to deny to her. She dreamed of finding great glory and power in a strange new world. But she emerged on the other side of the mirror in a harsh cruel world beset by demons and troubled by division, conflict and racial animus: the world of Remnant.

Now, years later, Sunset has completed her studies at Canterlot Combat School and is ready to attend Beacon Academy. She hopes that in the more progressive Kingdom of Vale her appearance as a pony faunus will not be held against her the way it was in Atlas, and she can rise as high as her talents permit and seize with both hands the destiny she still yearns for.

Sunset finds herself assigned to lead three fellow freshman at the Huntsman Academy: Jaune Arc, who dreams of becoming a hero elevated above all others; Pyrrha Nikos, a peerless warrior who has everything that Sunset wants and hates everything about it; and Ruby Rose, a simpler and more honest soul who simply wants to save as many people as she can, and who might just light the way to their salvation.

Together they are Team SAPR, and together they are plunged into a world of mysteries, magic, allies and enemies, robot girls and Atlasian black ops experiments. It won't be easy, but if they can work together, teach Jaune how to fight and maybe learn to get along as friends along the way, then they might just save the world.
