You are on the way to work/school/etc when you see a pony. What do you do? This is a choose your own adventure of the true variety, with all the choices laid out and waiting for you to finish.

Inspired by various "zombie apocalypse but with ponies" stories written for /mlp/'s transformation threads. Celestia has invaded our world, and infectious cartoon ponies are quickly overwhelming humanity. But why is the Princess of the Sun so interested in you? And could this entire invasion be your fault?

In the alternate timeline where Sombra was not stopped, a human finds himself suddenly in Sombra's body... just after the dread tyrant has conquered Equestria. Now trapped in a world where just about everyone hates him, he must try to keep up the illusion that he is the villainous conqueror, while at the same time try to win over his new subjects.

However, this will not be so simple, as the real Sombra is not quite dead... and he is most definitely not happy.

Part of The Ocean Of Time series.

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.

Chapter 24: In progress.

I’ve been in Equestria for over 1500 years, and the memory of what I did to Luna and Celestia is still there, like a dull ache that will never go away. As an immortal, I’m going to have the next few thousand years to get used to it. Despite that, only thirty years have passed back on Earth. I wonder what’s become of Luna since we traded places. Is she alive? Dead? Married with kids?

My name’s Catherine, and you’re probably wondering what I’m babbling on about. If you’ll bear with me, I’ll start where it all began.

Tags (character and otherwise) will be updated as necessary. Rated teen for strong themes.

There are 100 billion stars in the Milky Way, and humanity is determined to explore every one. We send probes, probes with the blueprints to reproduce human explorers upon arrival. Uninhabited worlds the galaxy over can be colonized and populated, until after many years they too can join the vast throng of interstellar civilization. But if a probe is very, very lucky, it will land on a populated world instead. Equestria is one such world.

Even so, it's far from perfect for colonization, not with an environment lethal to human life. But each probe is resourceful and armed with the greatest machine intelligence mankind has devised. If placing a human mind into a newly manufactured human body won't work, it will just have to get a little more creative.

This story was written at the behest of Canary In The Coal Mine, who is sponsoring it on my Patreon. As usual, cover by Zutcha. Editing by Two Bit and Sparktail.

Fantastic prereading help from: Chyre, Danger Noodle, Doctor Disco, and Doggyshakespeare (who also did the Esperanto translation). Thank you all for helping to make this story more readable and more consistent for everyone.

Our protaganist's life (mine) turns from dramatic to tragic in a single moment...but then an out-of-left-field event happens, and I find myself in an alternate universe version of My Little Pony: Friendship is Magic where the only difference seems to be Queen Chrysalis hatches a new queen years before the 1,000th Summer Sun Celebration...and I'm that new queen.

Jumping in on this particular bandwagon. Tagged "Gore" for the opening chapter (and possibly later chapters) and "Sex" because you can't mention any part of the reproductive process without the sex tag on this site.

When you're waking up without your gear in strange wildlands; the last thing you'd want to do is panic.

So what do you do instead? You get to your damn feet and start looking for a way back to civilization.

Rated Teen for some harsh language.

The mission continues in [Remastered Reality]

Please note that the sex tag only applies to this story due to nudity being in one of the early chapters, and in some of the later chapters. It is brief as it may be but no actual sex may take place. Do not let that dissuade you though, this story dose not focus on the subject.

[Declassified Imperial Mission File]

DESCRIPTION:

The Angel Class Sentinel Type Alpha is one of the few experimental sentinels created by the princess of the Harmonic Empire. Unfortunately for her she was BADLY damaged by a stolen angel and was being sent to the Capital to be repaired, she never made it. While on board a transport ship that was about to go through a jumpgate it was attacked at the worse time. As a result the ship get sent to Equestria for its contents to be discovered by the mane cast. New friends are made while new deadly (totally not kid friendly) enemies are made in the shadows. Many questions are to be answered while many more are to be found. Read on if you dare.

Twilight Sparkle finally achieved her destiny. She was now a Princess of Equestria, and needless to say her friends were surprised. When a second, unicorn Twilight Sparkle appeared alongside the new alicorn, even Princess Celestia was shocked. Now the Elements of Harmony must help the pony make friends and learn magic, as well as get used to her surprising un-Twilightness.

Meanwhile, a 17 year old high schooler with nothing to do during summer hits his head and wakes up in Equestria. He must now learn how to live his new life as Twilight Sparkle's "twin sister" and survive in a town where a catastrophe happens every Tuesday or so.
