"The Doctor of Equestria"
Chapter 1: Redirected Course
Rose, thought the Doctor,she's gone. He knew the risks. He could never see her again. He sat, alone again in the TARDIS. Companions only bring pain. He knew he was lonely, he'd been told countless times. The life of a Timelord is a solitary one; but not only that. The LAST of the Timelords, the only one left. There'd be no one else to remember the lush fields of Gallifrey, the colored hues drifting throughout the skies, the maddening spiral of the time vortex. No one else. He was alone. He was the last.
"That's enough. I can't stay like this. I need to move on. There are always places to go, people to meet, all of time and space! At times like this, I do what I do best. Allons-y!" after going through his average routine, he had finally finished setting his desired location into the TARDIS.
He wanted to see it just one last time, just to remember his time with Rose. The TARDIS began it's whirring and they were off. However, something was wrong, something was very, very wrong.This shouldn't be happening! The Doctor thought. The trip became turbulent, the TARDIS twisting and spinning, sending all things unsecured hurling to the ground, including the Doctor himself. Sent flying across the console, head colliding with some jagged edge or another, leaving him unconscious.
The Doctor woke up to a different world, one more brightly colored, where the clouds looked like swirls and all plants were in bloom. Most people might have been slightly worried, maybe even scared; but the Doctor wasn't most people. He looked upon this new place with wonder and curiosity. Well, a more accurate description would be like a child in a candy store. "What is this place?" he said aloud.
"Oh, I'm so sorry, Twilight! I just don't know what went wrong." the Doctor heard a new voice say. "It's okay, Derpy. Just be more careful next time." he heard another voice reply. The Doctor took a step towards the sounds, then realized: why do my clothes feel so big on me? He stared down at his legs and in return he saw HOOFS. WHAT. THIS CAN'T BE HAPPENING. AM I- A PONY? AND STILL NOT GINGER! HOW WILL I EXPLAIN THIS TO ROSE? WHAT AM I GOING TO DO? HOW WILL I HOLD MY SONIC SCREWDRIVER WITHOUT GETTING SALIVA ON IT?!
Oh... Rose, he remembered.
"No time to think about that now! I am a PONY. Must have regenerated while I was in the TARDIS." The Doctor shed all of his now too large clothing, except for the tie and sonic screwdriver, of course, and he began to head into town.
