The Doctor always travels with a companion, usually a human. But when he appears on a world that he has no prior knowledge of, he picks up a new companion. One that is not human, but a pony named Twilight Sparkle.

Now that the Doctor has a new companion, what crazy adventures will they encounter in space and time?

Note: The Doctor being used in this story is the tenth incarnation, and he is not a pony, he is the humanoid Doctor. And this is not a romance, it's an adventure story.

One Doctor has just had himself removed from his universe in order to save it. The other is traveling alone after a disagreement with his wall-eyed companion. They are in for just a bit of a surprise when their TARDISes collide in transit.

Geronimo.

The Eleventh Doctor (aka Matt Smith) is bumbling about in his Tardis when a crazy timey-wimey happening finds him in Equestria, a land from a children's cartoon. Despite the idea that being in the world of TV ought to be impossible, he's found himself turned into a bowtie-wearing pony in a pleasant little town known as Ponyville. What's more, the people there won't stop calling him Doctor Whooves! In order to get bet back into his own Time Lord form and out of the impossible world of My Little Pony, he may or may not have to make some new friends, fight some villains and pull out his "savior of the universe act." Geronimo!

This is a different take on Doctor Whooves, and also a sleep-deprived Doctor Who/MLP crossover idea I got in the very early hours of the morning so it could easily be rubbish. It's not meant to be terribly serious, but it's also my first fic so go easy on me. More characters could come and the rating could possibly change.

A blue box has fallen out of the sky, and crashed right into Twilight's Library! A strange brown stallion, calling himself the Doctor stumbles out. Soon after, strange stone Pegasus are everywhere, one of resident weather ponies has vanished, and Twilight is tossed in the middle! The Doctor and Twilight have to find out what's going on, before it's too late!

The Doctor winds up on a far off planet inhabited by pony-like creatures. The planet seems peaceful enough, but strange things keep appearing and disappearing, and he decides to take a deeper look into this subject. Things don't go entirely as planned, though, when he comes across someone very familiar.

Applejack has many secrets. She is much older than she looks. She is also smarter than she looks. Not only that, but she isn't very fond of Princess Celestia. She’s also searching for a long lost friend. Last but not least, she’s a time-travelling immortal alien hunter with a secret paramilitary base hidden underneath her family barn.

Stranded in a different time from when she grew up, she hides herself in plain sight, lying in wait for the chance to prevent a horrible future from emerging. Can she change history, or is she doomed to spend eternity watching everyone die at the hands of the greatest evil she has ever known?

A story written with diary entries, present day action scenes, dialogue, secret documents, and little to no editing.

Crossover with Torchwood. The Doctor will not actually appear in story line except in flashbacks.

Based on Defender2222's epic fanfic the Secret Origins of Scootaloo!

The Sequel to Number 12.
The Doctor and Twilight leap into the future, though it may be a far darker place than they envision. In the mean time somehow the Doctor keeps crashing around Ponyville, something to do with Fluttershy, but what?

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.
