The potion used to transform people into ponies has gone through many, many interations. When one of the older potions is used, results aren't quite what was expected.

EDIT: I used a piece of fanart which I thought was wonderful as the cover image :3

The Starship Enterprise and her crew must deal with a scientist haunted by his past, armed with a tool that could either revive his lost world in a new form or bring untold destruction. Meanwhile, the last two members of a dying race have made their way into the Enterprise's holodeck and have started up a simulated world to live in, populated by colorful talking ponies that seem to transcend the limitations of normal holodeck characters.

From another perspective, Twilight Sparkle and her friends must deal with strangers from another world who make claims that shake the very foundations of Equestrian history, science and philosophy. Can even the Magic of Friendship stand up to the possibility that the world is a simulation? Or do the ponies have what it take to prove to the strangers the truth of their existence?

a thousand years have passed since mankind had met, learned, and distroyed the land known as Equestria.
they had decapitated and sealed away the princess known as "celestia" and created a labor force of ponies to do the businesses bidding.
but what if they were wrong. what if instead of destroying equestria.. the just distroyed the link between the worlds?

the Goddess Tenebrae has always reincarnated as a human ,but this time something has gone wrong.

When Princess Celestia calls the Mane Six to her castle in Canterlot for an urgent meeting, what will she tell them? More importantly, how will it affect their friendship, Ponyville, and all of Equestria?

Note, I didn't make the picture this guy did http://kagetakaidoragon.deviantart.com/ check it out, it's amazing!

In the many years after the Conversion Bureaus' shutdown, Twilight Sparkle is tasked by the Princesses with finding the last living human on Earth, Isaac Hamilton, and learning the story of his past. What she hears is a tale of loss, tragedy, joy, and the discovery of one's place in the world. But how much longer would that place last with what Twilight has to tell him?

Earth pony, pegasus pony, unicorn; a human entering a Conversion Bureau will end up as one of these three pony forms. But there is a secret provision, to which all Bureaus must adhere utterly, should one unlikely but intolerable transformation somehow occur. The absolute monarch of Equestria fears nothing from the human world. Nothing save this. Lillian Fogarty wanted only to be a simple pony in Equestria. Sought by the combined forces of Earth's corporate government and the might of Equestria itself she finds herself an abomination in both worlds, her survival almost certainly an impossibility.

When science goes awry sometimes Pinkie's fourth wall breaking skills break in their own ways...

If you enjoyed my story, feel free to carry over into the sequel: Ponies on Bronies. If you just finished I have a link at the TBC on the last chapter that links to the sequel.

The following link goes to the original: Archived Ponies on Ponies.

This story is rated EL (Every Luna) for mild language and emo Dash.

It has also come to my attention, after nearly a year, that Ponies on Ponies showed up on an episode of The Brony Book Club regarding Pinkie Pie and was incorrectly cited. Said episode can be found here, head to the end if you wish to find out what this story isn't. Head up to about 49 minutes.

FMTM fully rewritten on December 12th, 2019.

Big Mac is also in this story.
