Twilight Sparkle is given permission to explore the Canterlot Caves after the invasion but, while inside, she discovers an ancient and primordial being, an literal force of nature, a creature said to be over a million years old...and it's now awake, how will she, and her friends, handle an adventure of a lifetime? Will they be able to get knowledge from a creature older than Celestia herself? Will they be able to bring it out of its well of sadness? Will they be able to show it that friendship really IS magic, or will it be driven away by their persistence of trying to become friends with it after it was betrayed and cause it to never been seen again?

Be wary Equestria for the Nine Tailed Beast has arrived!

Crossover with Naruto/After the Naruto Anime, if you hadn't figured out yet

After so long, the barrier preventing the monsters of the underground from feeling the sunlight on their skin (or fur, scales, bones, etc.) has shattered. Everyone is exploding with anticipation to see the horizon from the top of Mt. Ebott, to feel the clean fresh air, and to experience the wonders of the surface. Giddy excitement turns to confused shock when everyone finds them self not atop a mountain overlooking the sunrise, but in a dark forest with an air of fear in the mist at their feet.

The lives of the residents of Ponyville get a little more interesting when seven visitors unlike anything Equestria has ever seen appear out of the Everfree forest. While they are intimidating at first (especially a certain blue one), they are quite friendly once you get to know them. There are only a few problems, they have nowhere to stay, and many more of their kind are coming.

Crossover between Undertale by Toby Fox and MLP:FiM. Set at the times of the True Pacifist ending and before the Season 4 finale respectively. Moderate spoilers for Undertale.

Brothers to the end. Where one went, the other followed. Unfortunately for them, that meant going to a land they know nothing about. Fortunately for you, their adventures in said land have been leaked out to the public. How scandalous!

A short story depicting the adventures of two hilariously silly skeletons. One Papyrus, another Sans!

(If you liked the story and favorited it, a thumbs up is also appreciated.)
(Apparently I was featured on 8/22/16. Huh.)

[DON'T READ UNTIL YOU HAVE FINISHED UNDERTALE]

Sans, after being defeated by the human Frisk, gets sent to Equestria. Will he be accepted? Will he help our favorite pony's? Or will the memories he contains from the resets break him and cause him to distrust everyone?

"Or will I just be to lazy to give a bone?"

[Expect bad jokes, slight tear jerking, and a Sans who remembers all of the times he killed Frisk.]

I am here. Right behind you when you're not looking. In your dreams when you can't help it. In your thoughts when you finally notice. Always watching. Always stalking. Bringing fear to your heart. Making it spread through your existence. Until fear is all you are. Then you're ready. Then you're mine.

He has faced the impossible...and failed against the impossible. He has had the chance to return to his home, only to sacrifice the chance for the sake of others. He is the prince of a fallen kingdom who has given everything to make up for the past. But now the samurai's journey takes him to a land of peace and friendship, where he has one more chance to make it back to the past. One more chance to undo the future that is Aku.

Written after season four. And yes, Jack will be a pony. In the past crossovers I've kept them as humans and for this one I wanted to try something different.

I own nothing.

'To whoever gets this message, we're in desperate need of help.'

'Equestria...Equestria is on the brink of being destroyed. Sombra, Tirek and many other villains are taking over our world. The Ambassadors of Harmony are nowhere to be found and Celestia and Luna...Faust, Celestia and Luna. I don't know who you are and I don't care, just as long as you can save us. And if you can't do that, then at the very least...'

'Avenge us.'

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...

My name's John. I guess my last name doesn't really matter any more. Life is ironic, isn't it? Life nurtures all kinds of species that can get along, but it also creates the species that kills others. In fact, there are some species, who's sole purpose is the death of everything but itself. I'm talking about diseases, of course. Viruses, bacteria, fungi, and even parasites. All my life, I found these things interesting. I loved studying them, so naturally I grew up to be an epidemiologist. When I wasn't studying diseases or doing other basic functions, I was playing one of my favorite games, Plague Inc. It's a game where you try to wipe out humanity using diseases. Over the years, I've become a master of the game, to the point where it isn't really a challenge anymore.

But, that all changed when the game sucked me into itself, and I wind up in a strange land, with even stranger creatures. But that isn't all. I've somehow gained the ability to create and control every single disease I can think of. Now, I have to survive in this harsh world, knowing that I'm one step away from wiping out the entire planet.

Like I said, life is ironic, right?

[Displaced fic]

To any newcomers reading this fic, I want to point this out. The story may seem confusing in the first five chapters, as I was trying to figure out how I want to write the story. I won't be getting rid of any chapters, but some small points might contradict each other across both of them. These points hopefully won't affect much of the future.
