Warning, this work of fiction contains multiple fourth wall breaks, massive silliness, and more than a trace amount of alicorns.
The author may or may not have snapped at times in the writing of this work, and it shows. Bring a towel, you may get wet.

After the Pandorica falls into the exploding TARDIS, it throws The Doctor through the very last crack in time, a crack through which he can cross universes.No TARDIS, no screwdriver, a whole new pony body and a certain unhappy plasmavore that fell through with him, The Doctor begins to think that perhaps his plan was not as fool proof as it could have been.

How will The Doctor protect the highly confusing, sentient ponies from the plasmavore that seems to be harbouring an unholy grudge against all things Timelord? How will he adjust to his new body? And most importantly, why does he have a sudden craving for...pears.

Well, at least he still has his bow tie.

This story is a sequel to The Eagle Is Sealed

While Luna spends her time chatting with the three astronauts onboard Columbia on the three-day trip back to Earth, the humans still on the planet have to deal with the fallout her appearance has caused. Unfortunately for Charlie, that fallout starts for him as Soviet interest .

Now they're after him. He'll have to avoid, evade, and straight-up fight the full might the Soviet spy machine can bring to bear upon one man. Hopefully it'll be enough to keep him out of their clutches.

For if they can't have him, they'll do their best to make sure no one else can, either.

This story is a sequel to The Eagle Has Landed

When President Nixon orders, you obey. And now that he wants Luna on the LM and heading home, how is Neil ever going to convince her to follow?
But it doesn't even get that far, as an innocent mistake endangers the mission.
And even as the mission is endangered, tensions are rising back on Earth. While the drama plays out in Mission Control, just what is going on behind the Iron Curtain?
No one knows, but it's certainly not conducive to Apollo 11's welfare.

Sequel here.

(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.

Princess Celestia tires of constantly being surrounded by decorum, deference, and formality, and decides to take a day off from being Princess. But visiting Ponyville incognito is harder than she expects. Will she be able to fit in and make friends without blowing her cover?

A My Little Pony: Friendship is Magic/ Sonic the Hedgehog crossover

WARNING!!! Contains big spoilers from the Sonic the Hedgehog (2006) game, as well as a few comic references.

This story contains no crazy crossover shippings, (although strong friendships are formed,) and is my attempt at creating a decent MLP/ Sonic crossover that does well at presenting both universes both with accuracy and depth. I have also tried to keep this so that it is as close to canon as possible for both worlds, although I naturally elaborated on some things.

When Twilight Sparkle and her friends are sent to go to the strange world of Mobius to defeat an ancient evil, they end up encountering a strange, spiky blue creature named Sonic. The ponies easily make friends with Sonic, but soon find that not all of the people on Mobius are friendly. Mysterious events lead to misunderstandings, while an evil villain known as Dr. Eggman is setting his eyes on Equestria as his new target.
And amidst all of this lies a great mystery, a mystery that will shed some shocking revelations on how Equestria and Mobius share a great deal of history, on the origins of the being called Solaris, and on a dark threat that both worlds know all too well.

Other than the listed characters, you will get to see the Cutie Mark Crusaders and a good deal of background ponies share in the adventure, and a bit of Discord, as well as a great deal of short appearances by other .

An old enemy with a new shape has made its way to Equestria. Can the odd pony with the blue box help Applejack and Applebloom stop them, or is cloud watching going from being a way to spend a lazy afternoon to a survival tactic?
