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'.

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.

Part of the PWNY-verse.

As the elements were unleashed, the Nightmare knew it was over. But it would not let it's fun end. No, it would not be left behind. It would find another world to bring to ruin. As for the poor sap that was left in It's place? He was going to get blasted, what did it matter what he ended up getting from It?

Realized there was no link, so I'm adding two, one here and one in the chapter. After the events of Don't Underestimate the Power of a Bored Mare , the juicy bits that I cant put in a T fic: Defining Love

Edit: I swear, half of you are uncultured heathens. The thing in the image with the Nightmare's hair is a substitute doll

I was living a comfortable life. Had a loving wife and son, money was absolutely no issue, everything was swell.

Next thing I know, I'm hearing voices, I can't move, I can't talk, I can't even breathe. Yet, I know I'm alive, though I don't entirely feel like myself anymore.

Then I end up being the last of survivor of my new race.

I'm not even human anymore...

-A HiE fic as a changeling in an alternate universe where MLP was never aired on Earth.
-Starts shortly before the end of Season 2.
***Slow updates! You've been warned!***

-Comments below contain spoilers!
-The [Tragedy] tag is there mainly because I can't put up the [Sad] tag, due to conflicts with the [Comedy] tag.

The Battle of the Blanks is over, the Blood Hooves are no more. The curse has been lifted and Equestria is safe once more. Or is it? Konrad Ford has survived the battle but is now the "Last Human" in Equestria. As the ponies have mistakenly thought he perished, he shows up once more, attracting more than just the attention of the ponies. Soon everypony will want answers about Humanity's past and knowledge, all expecting Konrad to tell them the great secrets of Humanity, a lot of which he'll have to lie through his teeth.

With all the attention on him, isolation from his home, and more renegade approach than what ponies would consider acceptable, will he integrate successfully into Equestrian society? Will he continue to win the heart of Luna or another mare, Humanity's biggest fan...Lyra. Or will he fall to chaotic influence of Discord and forget the lessons of the show he loves so much?

The aftermath may prove to be a great beginning for Equestria or perhaps it's demise.

Ponies are enslaved. Humans are in control.

Nolan Anderson didn't want to be whisked away to a land full of discrimination and judgement. Yet he was there anyway. He just wanted to get by another day in his own world, no matter the hardships. Being a part of S.W.A.T. meant being the best he could be with what he could do. Little did he know he would apply his skills in a magical world, where the ponies think he's an evil human, and where the humans think he's a pony sympathizer. As crazy as everything is, Nolan wants to get back home, a feat that seems impossible, even in a world full of magic. However, the difficulty won't be getting back to where he belongs, but finding allies in a place where trust is rarely given, and earning it still.

I have never been a part of S.W.A.T., nor have I done extensive research on it. I have only taken a quick look at some procedures, weaponry, and armor for the purposes of this story. If you find something that doesn't seem right, please let me know. Also note I have taken a few liberties with how S.W.A.T. works that I will not change.
