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.

The Last of the Time Lords. The Oncoming Storm. The Predator, those very names ring fear throughout the cosmos, and for good reason. Good men don't need rules, and there's a very good reason the Doctor has so many. Just coming off from a true Voyage of the Damned, the Doctor finds himself in one very new situation that he can safely say in all of his 900 years of living, he has never experienced before. Crash landing (Well okay, maybe that isn't quite so new at all for him.) in a land of talking ponies. And now he's one. Well, guess there's only one thing to do. Pretend he knows what he's doing and just do what he's been doing all his life. Run. Do a lot of running. And who knows, maybe he'll find a friend, and possibly more in the local Princess of the Sun. One thing to say to that, really. Allons-Y!

(A rewrite of Once a Time Lord, Now a Pony as it was meant to be, giving Ten and the MLP characters the written justice they deserved but I failed to give them in my first outing.)

Takes place directly after Voyage of the Damned for the Doctor, and Pre-Season One for MLP.

Traveling between parallel universes is impossible, especially during the process of regeneration, but the Tenth Doctor doesn't have time to question the facts. He's just been thrust through a tear in the fabric of reality, gotten a new body, and landed on a planet called Equestria. Specifically, he's landed in the worst possible place in all Equestria – somewhere that's ready to unleash a “big ol' storm of chaos”.

That's just the beginning of the Doctor's strange new lease on life: there's a whole host of mysteries to explore. Who is Derpy Hooves, the gray pegasus who understands more about him than even she knows how to explain? How does Princess Celestia already know him? And what's the truth behind the Order?

Above all, the Doctor needs to discover if this new universe can heal the wounds he suffered in the last. Only one thing is certain: there's an awful lot of running left to do.

(Warning: For those of you who haven't watched up to the Doctor Who episode 'The End of Time'... spoilers. Also, this story begins between Seasons 2 and 3 of FiM, and things start to... diverge from there.)
