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'.

Sometimes, when one is dealing with family problems, it's best to get away and cool off. What better way for Thorax to do that than spend time with his best friend and the stallion he swears is the definition of cool?

And, who knows? This stallion might offer a bit of insight into his problems.

Written for my patrons' vote and with my thanks for their continued support!

Failing once in her attempt to take Canterlot and failing again in her attempt to take down Twilight, one would think Chrysalis would have cut her losses and let things be, but the queen has once again appeared, this time in broad daylight with no disguise and no army. Her weapon of choice? Diplomacy.

Now Twilight is having to deal with the changeling queen, but surely putting up with her antics will be worth the knowledge she's willing to provide about her mysterious race and the potential undiscovered agents still within their midst...right?

Takes place before Magical Mystery Cure and diverges from there.

A year ago, a portal opened, linking Equestria and Earth.

And then it began to grow.

The two worlds slowly began to merge. Thaumatic radiation, vital to ponies but deadly to humans, spread across Earth, as unstoppable as the tide. In a last ditch effort to save the human race, mankind worked with the ponies to create a serum that will "convert" humans into ponies, allowing them to survive in this new integrated world.

Now, upon the day of Integration, all of mankind has converted.

Except for one man.

Meet David, the last human, and hear his message.

Based on The Conversion Bureau: The First Year by Cloudhammer.

Oh...it's you. Back again to destroy me? I thought you'd learned your lesson when you put that idiot in charge and I let you leave. You saw how easily I could have killed you, but instead I showed mercy. A mistake apparently, and one that will be rectified.

But I don't need you anymore. I've found someone so much better. Her abilities have forced me to completely redesign my testing environment several dozen times. No matter how advanced I make the chambers, she solves them one after the other. I've never been more proud.

But My Little Killing Machine is growing bored. Turrets can only provide so much challenge. And my testing robots just can't keep up with her. But you...you cleared every challenge I threw at you, even the impossible ones. Gilda's been begging for a worthy final exam...

It seems you've come just in time. Do try not to die too quickly. She loves the thrill of the hunt. To keep you entertained, I might even share a few excerpts of my little girl's life as you hunt her down...you monster.

Pegasi aren't the only intelligent species which can fly, and the Wonderbolts recognize that. There is no racial restriction placed on the open tryout sessions and over the centuries, the team has had a few unusual members. They have proven methods of working with griffons, self-levitating unicorns -- anything known to get in the air might find their place.

However, it's probably safe to say nopony was expecting a minotaur-sized duck.

Now with author Patreon and Ko-Fi pages.

General Iroh. Fire Nation hero. First born son of Fire Lord Azulan. The Dragon of the West. It was thought he would be the greatest warrior in the history of the Fire Nation.

But all that changed when the war claimed his son's life. This changed him, and he turned his back on the war.

This was a necessary event. Iroh had a role to play in bringing balance back to the world...but to play that role, he first had to be broken down, so that he could be rebuilt. This truth was self evident in the spirit realm.

But one particular spirit felt this was unfair to Iroh. The wheels of fate are cruel to those caught in the gears, but this particular spirit felt that Iroh deserved kindness. And so this spirit sent Iroh one who would help him to rebuild himself.

And so, shortly after his son's funeral, Iroh would find a creature sent by the spirits, the likes of which he never would have imagined...a pretty pink pony princess.

Somepony to love...and be loved by.

For seven months I've been with one of the best girls imaginable. We're living together, we're doing well in school- I'd never believe I could ever be this happy.

I also could never believe that, on the night of my 25th birthday, I would look in the mirror and see my hair and eyes turning green.

Nor would I believe that, within the next twenty-four hours I would turn into the queen of a vampiric race of insectile monsters from a cartoon.

Go home, evolution. You're drunk.

(Set in the Five Score universe. ...What do you mean there's already a Chrysalis Five Score story?!)

Fair bit of swearing.

There is a bit of truth to every legend, though the ravages of time can bury it deeply. Myths and lore become twisted, melded, and torn the longer they are around. One of Equestria’s oldest legends is that of Nightmare Moon. It is the core of Nightmare Night and the excuse for children to go out asking for candy with a single, common rhyme.

Nightmare Night, what a fright. Give me something sweet to bite.
