Bómù Guāng Shǎn, the Prince of Friendship, asks Mèng Huàn, the Prince of the Night, for help investigating a mirror universe. The ponies there call it Equestria instead of Cōng Mǎ Guó, and it might have a few other differences, too...

The original, short story version came in 10th in the Writeoff Association's Feb. 2016 contest, "Look, I Can Explain." The cover artwork is by huhulin from Vectorstock, and overflowing thanks go out to M1Garand8 for help with the Mandarin names and the hànyǔ pīnyīn to render them in Latin characters.

When the Elements of Harmony defeated Discord, they did their job too well, and completely undid all of the things Discord directly did...

... Like send a subcontinent from earth into a pocket dimension so he could focus properly on his toys. And now Equestria has appeared on Earth.

Yet, neither side was completely ignorant of the other. On Earth, there was the show "My Little Pony: Friendship is Magic" and in Equestria there was the ever popular movie serial "The Dark World: Technology is Courage" which was a favorite of colts everywhere as well as the "Pumans".

And now both sides learn through an event that the other is real. Come join us as we watch as both sides learn to work and live together. And as they find out that events on their respective fiction was not as nice as it seemed as we widen the lenses of the view points...

A Round Robin created on SpaceBattles of which I am a participant and am posting with all their permission.

Pandinus Imperator (You can call him Pan, he won't mind) is knocked back in time during the Canterlot Invasion, and accidentally kills King Sombra on arrival. Instead of being executed, the changeling is surprised to find himself being hailed as a hero, and is promptly put on the throne as the new monarch, the Crystal Emperor. However, Pan now faces a great many problems, among them Celestia and Luna, who seem certain that the changeling is secretly up to no good, as well as several political factions secretly plotting to undermine his reign. There's also the tiny problem of the constant snowstorm that threatens to cut the city off from the outside world permanently.
The Crystal Ponies need a hero now more than ever before. Why did they get a changeling instead?

While not truly a part of Bucking Nonsense's Changeling-Verse, the same rules regarding changeling abilities and society apply.

Broken and beaten after the failed Canterlot invasion, Chrysalis desperately searches for a way to save her hive. The answer comes to her in the form of an ancient spell that allows travel to other worlds. Starving, feeling left with little choice in a world that despises and fears them, Queen Chrysalis and her Changelings pack their metaphorical saddlebags and ship off into the unknown.

The world they discover is unlike any other. Strange and powerful creatures inhabit the land; not only that, but they also find themselves imbued with new powers. Even better—love is abundant and easy to obtain: all they have to do is fight for their lives in arena-style tournaments, enter beauty pageants, musicals, and other demeaning activities.

As Chrysalis and her ’lings adapt to this new world, they must also be careful. This new paradise comes with its fair share of dangers: other monsters competing for affection, unkind masters, and even an organisation that would seek to enslave and experiment on them.

Finally, why does someone named ‘Arceus’ keep sending Chrysalis Legendary Pokémon Application forms?

I'd like to thank Pascoite for being my Pre-reader. You are a legend and a master of your craft. Thanks again bro.

Equestria is expanding unstoppably. The Conversion Bureaus are working at peak capacity. It looks absolutely certain that Celestia will replace humanity with ponies.

But then one niggling flaw appears in her plan. You see, humanity's religions, while dismissed by Celestia as just more evidence of human barbarism, are correct in at least one respect. Humanity has a loving father, and what Celestia is doing makes Him angry. So angry in fact, He's going to do what He hasn't done since ancient times: smite.

Seems like Exodus is being reenacted, and guess who's playing Pharoah?

The Barrier: a naturally-occurring wave of magic that formed soon after the portal to Equestria appeared somewhere in the South Pacific, enveloping Earth with an inevitable tide that has destroyed all life on the planet, all despite the best efforts of man and pony alike. Now, the ponies are left to pick up the pieces and try to preserve what's left, while averting the vacant gazes of the mindless Newfoals left from one of their failed attempts to save what they could.

But there's one thing that all seem to have forgotten, from the ponies of Equestria to the strange multitudes of species in the universe with their sights set on Earth: and it's that you can't keep a good apex predator down. You can only hold them up a little while...

Dr. Albert Wily...mad genius, evil scientist, brilliant roboticist, wanted criminal, would be world conqueror, loving father... Wait, what was that last part?

When Dr. Wily wakes up one morning with a tiny unicorn inexplicably clinging to his bald head, he is more than a little flummoxed. Unknown to him, this tiny creature is about to turn his entire life upside down, worm her way into his heart...and make his dreams a reality.

Can you feel the Wub tonight? Mega Man sure will.

Megan Richards is a normal, everyday wife and published author of 'My Little Horsey'... however the tales she writes about aren't fiction, but stories from her past. She thought she put the world of ponies behind her, but sometimes the past has a habit of catching up with you...

G1 meets G4 in a hopefully epic tale of the past, the present and the future.

I own nothing, also, minor cameos from other Hasbro properties such as Jem and the Holograms, Transformers G1 and GI Joe.

Sequel: The Conversion Bureau: United We Stand

Side-stories and mini-arcs not able to fit into the main narrative: Side Stories of First Contact

There are many stories where Twilight tells off her friends after the Wedding. But that's not really Twilight's bag, she gets worried she's failed, or depressed, not angry. So here is a different bridal path, one where Twilight acts decisively to try and redeem herself in the eyes of her friends and sovereign, and ends up travelling to places she never imagined, facing dangers and foes she never dreamed of and making even stranger friends. Of course, there is still a 'reason you suck' speech delivered, but delivered by the last person anyone would expect...
