While on a routine mission the Enterprise is called to check out an anomaly in deep space.
However, through a chain of events, that are completely not Kirk's fault, he and a red shirt fall into the anomaly and awake in Equestria. As ponies.
Can Kirk handle being in a land of ponies and magic? How will he fulfill his contractual obligations to some how rip his uniform shirt? Will Ensign Ricky live to tell the tale? What is Harcourt Fenton Mudd scheming about while in the brig? What is Sulu doing in his off time? Why am I asking you this? And most importantly, can the crew of the Enterprise bring them back, or even survive without Kirk?

Cross over with classic Star Trek
This story takes place a week after the counter clock incident from Star Trek The Animated Series,
And between seasons Two and Three of My Little Pony Friendship is Magic

It is the year 2552 and the Pillar Of Autumn has just entered Slip space to escape the Covenant fleet at Reach. A malfunction occurs with the Slip space drive and sends the Autumn and her crew into unknown space. The first planet that comes into range is very Earth like, and is giving off intelligent life signatures. What they don't know is that their only way back home is on this planet. The Autumn dispatches a scout party and what they report back is unbelievable. A world completely inhabited by ponies, millions of them..... Welcome to Halo: Equestria.

I'll add in more character tags as they are introduced in the story.

This story is a sequel to My Little Caboose: Blue is Magic!

It has been one month since the Elements of Harmony were used to trap Discord again, and it has been one month since Twilight lost one of her closest friends, the only consolation of which being that Church was finally getting some well deserved rest. At least, that is what she and the others believed. Discord, still trapped within Church's mind, has been picking away at his sanity the entire time, messing with his memories, making him forget what was real and forcing him to remember what wasn't. When he finally escapes, will Church be able to distinguish between reality and the memories Discord tampered with, or will his slim grip on reality finally give out?

If the ponies he is led to believe are his friends are of any indication, probably the latter.

Instead of being killed in the cold Antarctic by Dr. Manhattan, Rorschach finds himself rematerialized in a strange new, pony filled world. He finds himself drawn into the lives of the ponies of Ponyville but some ponies fear that this sociopath will bring danger and darkness to an otherwise peaceful existence. Will the mane 6 help Walter Kovac find peace within himself or will he bring them all down with him in his cold views of reality and existence?

In the aftermath of Discord, Equestria becomes accessible to the universe as a whole. When the USS Enterprise stumbles upon them, will they accidentally shatter the peace this world has known?

(The continuation of this story-verse is Star Trek: Pegasus.)

This is a direct sequel to my previous fic The Quandary of DisQord and is, of course, another Star Trek: The Next Generation / Friendship is Magic crossover. This time, however, Q has decided to bring the crew of the Enterprise-D along for the ride as well.

This is a much lighter story than Quandary was (since Quandary was the story of Discord's reign prior to his first defeat, it was bound to be a bit on the dark side). Also, be warned, though I tried to keep them to a minimum, there are still a few references to and spoilers for Quandary in this fic here, so I'd obviously recommend reading that one first before reading this one. Though, at the same time, this one is hopefully self-contained enough that you wouldn't necessarily have to read Quandary first in order to understand anything, if you don't care to.

Also beware, there is a bit of very mild one-sided shipping between one of the ponies and one of the humans, but nothing super serious or squicky or anything like that. And the Discord/Celestia ship from Quandary is touched upon again, of course. Just thought I'd mention it here, in case someone might be turned off by that sort of thing.

As with Quandary, extensive (and spoiler-filled) Author's Notes can be found after the end of the final chapter.

Friendship, the Final Frontier.
When a Starfleet ship discovers that the Orion Syndicate is enslaving ponies, her commander decides to do a good deed and return the rainbow-maned pegasus home to Equestria. Things don't go smoothly for the crew of the USS Judges, but what they find may be one of their biggest discoveries ever.
A Friendship Is Magic/Star Trek Online crossover.

(The sequel to this story is Where Nopony Has Gone Before.)

This is a Star Trek: The Next Generation / My Little Pony: Friendship is Magic crossover fic (though it's mostly just a FiM fic since none of the Star Trek: TNG cast except for Q show up, though a few are briefly mentioned). The frame story is set immediately after the TNG season 3 episode "Deja Q." The story being told to Q2 (who is simply called "Q" rather than "Q2" in the fic itself) by Q is about Q's existence as Discord from his first arrival thousands of years before the events depicted in the play in "Hearth's Warming Eve" up to the end of "The Return of Harmony."

The three main characters are Q/Discord, Celestia, and Luna, and there is much star-crossed shipping between Discord and Celestia. The main 6 from the show only appear near the end and don't play that big of a role outside of a partial retelling of "The Return of Harmony" from Q/Discord's point of view.

Celestia's parents are based upon fanart that can be found on DeviantArt ("Little Princesses" by SpyrotheFox, the original creator of them, and "just keep flapping" by egophiliac), though their names are ones I came up with myself.

An Alternate universe that deviates from the storyline seen in No, I am NOT a Brony, GET ME OUTTA EQUESTRIA!!! in which Celestia reveals at the Gala that she can in fact send him home.

Eager to do exactly what he's been waiting to do, he grabs his Clovevellian Staff and computer, and is promptly sent back to Earth, free from any more pony (and no, he will most certainly NOT be watching the show either).

A year passes and TD is happy back on Earth and has a job as an RA at his school. You know, the kind of job that requires a lot of human contact.

That's when the box shows up...

Yes, this is a TD version of My Little Dashie. Don't read if you don't like either MLD or TD in general.

When your life is as dull a gray as the world that surrounds you, the mundanities can make it all seem meaningless. Sometimes all we need is a little color -- or six -- to reintroduce us to what truly makes life worth living.
