Humans currently poses an entire intergalactic empire, the aid of their brilliant technologies, and the fundamentals of dark energy have allowed them to succeed to a type three civilisation.
A human named Jack decides to buy a planet called “Harmony” on the intergalactic market. This planet holds residence to dozens of sapient species who all are primitive lifeforms.
He decides to transform into one of the native species, with his intention to cause as much havoc/chaos as possible. At the time of his arrival, most of the world hadn’t seen conflict for well over 1000 years. He plans to change this, by encouraging new ideologies, starting a technological black powder arms race, and ultimately causing wars.

He may look evil to the natives, though according to the intergalactic government, he is implementing nothing illegal. His planet means his rules.

May or may not include Communists

This story is set in Early Season Two, a few episodes after “Return of Harmony”. This is an alternate universe and thus Equestrian girls don't exist, humans are basically just a myth.

Constructive criticism is welcome.

This story is cancelled. I'm currently working on another one, with a similar setting/universe.

Hello, my name is Twilight Sparkle. My brothers are Shining Armor, captain of the Royal Guard, and a dragon named Spike that I hatched when I was little. I have five friends that help me wield the Elements of Harmony, artifacts that protect Equestria from evil. I have a few other friends that are less important, but still great ponies nonetheless.

One catch, though. I am also a changeling Queen, and the friends and family I just mentioned are all my subjects, and children as well. They don't even know it, but everything's working out alright, so no reason to tell them! After all, it's not like a giant wave of love energy could suddenly reveal all the changelings in Canterlot, right? Right?

Part 1, Revelation: Twilight Sparkle meets an old enemy that reveals a secret she's kept since she was named.

Part 2, Recollection: The Elements of Harmony try to get to the truth of the matter, changeling Queens begin their game of chess, Queen Citlali takes her Hive and runs from Canterlot.

Part 3, Reformation: Queen Citlali begins to grow her hive, Whitetail Hive takes some time to get used to the news, Princess Cadance dreams of a dark creature.

May 11-15, 2017: Featured for the maximum time... whoa.

The Galactic Empire discovers an odd star system in the outer rim. Tasked with scouting the first planet in the system, Scout Trooper TS-588 and her partner TS-571 make unintentional first contact with a new alien life form.

Ponies.

This story is a sequel to A Changeling Named Sin

After three years of running and fighting for not only her life, but the ones she is trying to protect, Sin is forced to train and perfect her abilities. Acid, a threat to all of Equestria looms over the land seeking to destroy the world as he pleases. It seems Sin is the only Changeling possibly strong enough to defeat him. With no signs of other Evolvers around, will this distraught mare be able to cope with the maddening effects of solitude?

*In this story, the changelings are based off of Season 2, so it's as if they've never given love freely. Sept 4th, 2017

Edit: Due to complications with the ongoing story - no direction for it to go off of - it has been cancelled.

This story is a sequel to The Signal

The Signal turned Equestria upside-down.
The Signal made savage murderers out of every unicorn in Equestria.
The Signal lingers still, preventing any hope of curing its influence.

Spike has found the Signal. He knows how to get to its source.

And he will shut it down, whatever it may be.

You might want to read the prequel first; this is not stand-alone.
Mad props to NAME Revoked for the cover image.
