Monsters. Mythical Beasts. Legendary Creatures. To humans, they're nothing more than stories. To the students at Canterlot High, their existence is a bit more believable. To Sunset Shimmer, the myths and folklore she reads about in English class could've been an everyday occurrence. In Equestria at least. That is, until she heard a story about a certain mountain.

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'.

You never expected your wish to go to Equestria to mostly come true, and you never expected to meet Flash Sentry, and you never realized just how little documentation you need to rent a woodchipper.

This will end well.

When drawing the "Pet her" panel in his comic, a brony brings Pinkie Pie to life.
He finds out that it's not a good thing.

You are a pony that experiences the love and trust of having somepony to love. A mare, having been torn apart from the hurt of heartbreak, comes to you in need of somepony to love I wanted to make a note that in this series, you will take many different forms: earth pony, pegasi. Each chapter is based on the premise that the last chapter didn’t happen and the next chapter won’t happen. So, each story is completely unreliant on any other stories. This series is based on the internet meme: doing hurtful things to your waifu. Each chapter is based on the assumption that that character has already undergone, her own “doing hurtful things to your waifu chart” and has had each of those items already happened to her. So, in these stories, you will be the pony to make her feel better. You are the protagonist. You’ll make her feel better. With that having been said, enjoy.
“No man stands so tall as when he stoops to help a child,”
-Abraham Lincoln.
for my purposes, I’m replacing the word ‘child’ with ‘mare.’

A human stays among ponies, mystifying them with his odd traditions and customs. It will be five years before Celestia and Twilight can send him back to his homeworld. Until then, Twilight wants to study him and have him experience pony culture. These are their stories.

Now Rated Teen because I kind of kill them on a regular basis, but they're immortal so they get better.

The continuing story of those in Canterlot Castle and the surrounding areas. With four immature gods running about, is anybody going to survive? Probably. However, with each day, the madness in Equestria grows and sadly I don't think anyone actually cares anymore.

It's time for Equestria's Crazies; a tale of love, of tasers, comedy and finally me, tormenting as many ponies as possible before I get bored.

[Head's up, this story is an Episodic series. Each chapter is it's own contained "Story" but really it's just whatever I want to happen on that particular day.]

Since her return and rescue, Princess Luna has been looking for some way to properly honor the six mares who saved her from herself, but nothing she has been able to think of has seemed meaningful enough to repay her saviors.

Nothing, at least, until she spends Nightmare Night in Ponyville, and gets to actually know the six ponies to whom she owes such a great debt. She realizes she enjoys their company, and wishes for them to spend more time with her, that she might grow closer to them.

So, in accordance with many fine and ancient traditions, and after thinking it over for a good...couple of hours, easy, she proclaims that she shall marry all six of them. Oh, and that Twilight will be marrying Celestia, too.

Now would be the appropriate time for everypony to panic.

This story is a sequel to Stardust

Twilight has finally returned home from the harrowing challenge that Discord set upon her, and the residents of Ponyville and the Elements especially look forward to having their dear friend returned to them.

Twilight, however, has changed. Still suffering from her injuries, almost incapable of using magic and haunted by the memories of her time on Earth, she becomes increasingly withdrawn from those who were closest to her. Will her frustration at her current state and her friends inability to understand her experiences cost her what she valued most before Discord's bet?
