Chapter 1 Brave New World

It was a calm day. The sun was high and shining brightly, a soft breeze was blowing, and everything was at peace. The calm was suddenly interrupted by a soft whooshing sound. As the sound continued, a large blue box slowly faded into visibleness. When the box finally became solid and fully visible, the sound abruptly stopped and the door on the front opened.

"Well now, this is a bit odd," a male voice with a slight accent said from within, "This is definitely not London."

Stepping out, the occupant of the box looked at his surroundings, squinting at everything, as if trying to make sense of what he was seeing.

"Looks like Earth," he said, sniffing the air and sticking out his tongue, "Smells like Earth. Even tastes like Earth. But definitely not London. Just where am I?"

Turning, he stepped back into the box and made his way to a large console in the center of the impossibly large room contained within.

"Lets see what the TARDIS has to say," he said to himself.

He began furiously typing away on the keyboard in front of him, as well as pressing various buttons and pulling different levers. Within a few moments, a screen came down from the ceiling and blazed to life.

"All right, where are we then?" the man said as he took a look, "Ponyville, Equestria on planet Earth. Wait, what? I've never heard of a country called Equestria on Earth. Blasted thing must be on the fritz again. I'll fix it later. For now, I'd best take a look around and see where I really am."

Pressing another button, the screen turned off, becoming a dark reflective surface. He was just about to send the screen away when he noticed something odd within the image of his own face being reflected back at him. Namely, the fact that it didn't appear to be him.

"What the…" he said reaching up to touch his face, "How is this even- Why do I have hooves? TARDIS, full body mirror!"

A large mirror rose out of the floor behind him and he turned to look.

"Oh, this is not good…"

The image of himself that he saw was rather surprising. Rather than the two legged, pink-skinned humanoid form he was so accustomed to, what he saw was a horse. A small horse, more like a pony.

"How is this even possible? Can Time Lords really take on forms like this? I've never heard of something like this happening, but then again, there is a lot I don't know…"

He looked over the body, taking in every detail. "Brown coat, brown mane and tail. Will I ever be ginger? Oh, hello. What is that?" On his rump, he noticed an image of an hourglass. "How curious… It doesn't appear to be brand and I don't think horses can be tattooed. It's almost as if each individual hair is a different color. I rather like that it's an hourglass. Seems rather fitting. Doesn't explain why I'm a pony or where I am. Wait, can ponies talk here? Oh I do hope they can. It would be a bit awkward being a talking pony on planet where ponies are silent. Best do some scouting while I try to figure this out."

As he made his way back to the door, the pony suddenly stopped and turned.

"Where's my sonic?" he said looking around, "I'm pretty sure I left it on the console over… There! Found it!" he exclaimed spotting a small metallic cylindrical object sitting on the center console.

He walked over to it and stopped, looking at it for moment before mumbling, "How am I supposed to pick this up? I don't have hands, I have hooves. I can't pick things up with hooves. But then again, I was just typing on the keyboard with hooves. Maybe I can pick it up…"

Reaching out with one of his hooves, the pony tried to grasp the object, but found himself unable to do so. He tried again and again, but each time was unable to actually grab the object.

"Oh blast it all!" he exclaimed turning away, "I knew it was impossible. Guess I'll have to go on without it."

As he walked away, he brushed a hoof along the console and suddenly, the sonic was in his hoof.

"Wait a minute, what?" he looked down at his hoof, very confused by what just happened, "How is this possible? This is a hoof, not a hand! How is it holding my sonic?"

He looked at his hoof for another moment, and then the sonic dropped to the floor. He stared it at for about a minute, then reached down and picked it back up.

"Hmm, well what do you know," he mumbled, "Guess these hooves are like hands. Now I just need a way to carry this… If only I had pockets…"

Placing the sonic back on the console, the pony walked off into another section of the TARDIS and found himself in a large room filled with rows upon rows of clothes. He looked at everything spread out before him and sighed.

"A limitless selection of outfits and none of them made for ponies. There must be something I can wear."

He walked into the massive collection of clothes and started looking through everything for anything that would work with his new form. Then, finally after a few minutes, he found it.

"Well, what do we have here? When did I get a saddlebag?" He picked the bag up and looked it over. "Either way, this should work."

He placed the saddlebag across his back and tightened the various straps, than went back into the main room and grabbed the sonic. Placing it into the saddlebag, he smiled.

"Not quite pockets, but it'll do."

The pony then quickly walked around the TARDIS, gathering up various things and placing them into the saddlebag. With everything finally in order, the pony proceeded back out of the blue box and into the outside world. He found himself in a clearing. There were clumps of trees and bushes all around, as well as a small pond with a small river running away form it. In the distance, the brown pony could see what appeared to be buildings.

"That looks like a good place to go. Should be able to figure something out there."

Making his way towards the apparent town, he began to see other ponies, many of them with brightly colored coats and manes walking about.

"Well now, that is just odd," he said, stopping a little ways outside of the town.

"What's odd?" a cheery voice chirped from beside him.

"All those ponies," he responded, not bothering to look to see who had just spoken, "Look at their coats. Ponies are not supposed to have coats like that."

"They aren't? Everypony I've ever seen has coats like that."

"Oh, right," he said to himself, "This isn't my world. The rules are different here."

"Not your world?" the voice said, sounding slightly confused, "What do you mean by that?"

"Well, you see, I'm – Wait a minute," he suddenly interrupted himself, turning, "Who are you?"

Standing next to him was a bright pink pony with a large, wildly curly pink mane. "I'm Pinkie Pie," she said with a large smile, "Who are you?"

"Oh, yes right. How rude of me. I'm the Doctor," he said with a slight bow.

"The Doctor? That's kind of a weird name," Pinkie responded.

"Yes, well, I could say the same about yours," the Doctor replied, sounding slightly offended, "But that's beside the point. You're a pony, and you're talking. Do all ponies talk here?"

"Huh? Uh, yeah," the pink pony said, confused by the brown pony's question, "I mean, sure there are a few mute ponies, but for the most part, everypony can talk."

"I see. How curious," he muttered, looking at the ground thoughtfully.

"You okay mister?" Pinkie asked, sounding concerned, "You're acting kinda weird."

"Hmm, oh yes. I'm fine. Perfectly fine," the Doctor responded, with a small smile, "Anyway, could you tell me where we are?"

"We're in Ponyville!" the pink pony said, bouncing up and down slightly, "Well, we're not actually in Ponyville. We're on the outskirts of Ponyville, but we're close enough to Ponyville to technically be in Ponyville, even thought we aren't."

"Ah, yes, right. Um, no. I know that already," the Doctor said, glancing at the town, than back at Pinkie, "What I meant was, what planet are we on?"

"Planet? Uh, Earth," Pinkie said, even more confused.

"Earth?" the brown pony said, sounding just as confused as the pink mare, "Are you absolutely sure? Are you absolutely sure that this is Earth?"

Pinkie nodded slowly, saying, "Yeah. I'm pretty sure that this is Earth."

"That can't be," the Doctor said, looking back at the town, "There's no way this can be Earth. I mean, sure it looks like Earth, and it smells like Earth. It even tastes like Earth. But Earth is definitely not inhabited by multicolored, talking ponies."

"Uh, yeah, it is," Pinkie said, looking concerned, "I'm starting to think you're not okay."

"No, no, I'm fine, I'm fine," he replied, holding up a hoof, "The only thing wrong here is this world."

"What's wrong with the world?"

"Everything!" he exclaimed, looking at her, "The TARDIS coming here on seemingly on it's own, me being turned into a pony, ponies instead of people, HOOVES! It's all just wrong!"

Pinkie took a step back with a nervous chuckle, and said, "Yeah, you're definitely not okay. I'm gonna take you to the hospital."

The Doctor opened his mouth, but before he could say anything, there was a loud roar from nearby. The Doctor turned towards the sound, muttering, "Oh, that does not sound good. Apple Pie, I need you to listen to me very carefully," he said turning to Pinkie, "I'm going to go find out what's roaring out there. I want you to go back into town and tell all the ponies to get inside somewhere safe for a while. And do not follow me."

Then, without waiting for a response, he ran off in the direction of the roar, not looking back. Pinkie stood there, watching him go, a very confused look on her face, then after a moment, called out, "Wait! Who's Apple Pie?"

The Doctor ran as fast he could make his strange, new, four-legged body go, looking for the source of the roar. Luckily, there were more and more roars, allowing the Doctor to easily close in on the source. Finally, he found it and quickly dove into a large bush.

"Well, well, well," he muttered to himself, "Now this is interesting."

Close by to where he was, a large, creature stumbled about, seeming to be looking for something to eat. The creature stood at about seven feet tall and had grey leathery skin, with a row of spike running down the length of its spine. Its head looked vaguely pony like, with rows of long, sharp, jagged teeth, and it walked around on four, clawed hoof like feet.

"What is that?" a voice whispered from next to the Doctor.

"Well, that appears to be a Jallpurian hunter, but it looks very… pony like," the Doctor said, once again not looking to his side.

"A Jall-what now?"

"A Jallpurian hunter," he replied, "From the planet Jallpis. Very nasty, very dangerous, interplanetary predators. But this one looks like its been somewhat turned into a pony. Just what is wrong with this place…"

"Interplanetary?"

The Doctor nodded. "Jallpurian hunters can teleport themselves to other planets. Once there, they scour the planet, looking for anything that isn't big or strong enough to fight it off, and eat it. They do this for a while, than move off to another planet. Luckily, however, Jallpurians can't teleport to planets they've already been to. Eventually, they return home, where they proceed to reproduce and then die. As I said, very nasty, very dangerous, and ultimately, very odd."

"So, what do we do?"

"We need to find a way to get it off world. Once we do, it won't be able to come back and everyone here will be safe."

"I see. And how are we gonna do that?"

"Well, I do have a vague idea, but I'm not entirely sure how to pull it off."

"Ooooo… What's the plan?"

"Well, if I can get it to - Wait a minute," the Doctor interrupted himself again, turning, "Cherry Pie? What are you doing here?"

"Whose Cherry Pie? My names Pinkie Pie," the pink pony said.

"Whatever, that doesn't matter. Why are you here?"

"Well, I couldn't just let some crazy pony go running off on his own after some big scary monster."

"I told you not to follow me!"

"No, you told Apple Pie not to follow you, and I'm not Apple Pie. Who is Apple Pie anyway? Is she one of Applejacks cousins?"

"I – What? No, whatever. Just, go back home, get everyone to safety, and let me deal with this, okay?"

Pinkie shook her head. "No way. Like I said, I'm not letting some crazy pony I just met go off on his own."

"Gah! Fine! Whatever! Just, do what I say, and try not to get eaten."

"Okie Doki Loki! So, what's the plan?"

"We lure the Jallpurian to the TARDIS and I take it to some other planet."

"TARDIS? What's that? You mentioned it before, I think."

"It's a special machine that can travel to other planets, lets just leave it at that for now."

"Okie Doki Loki. But, how are we gonna lure it?"

"Like this," the Doctor said, and leapt out of the bush, shouting, "Hey! Jallpurian! Come and get me!"

The Jallpurian turned and roared at the Doctor, then charged at him.

"How is this a good plan?" Pinkie shouted as the two ponies ran away from the charging monster.

"When a Jallpurian sees prey, it chases it until it catches it!" the Doctor shouted back, "This way, we'll be able to get it to the TARDIS, and it wont go into town!"

"Okie Doki Loki, but where is this TARDIS thing?"

"Just follow me!"

The two ponies ran as fats as they could, the Jallpurian close behind, roaring as it ran. Finally, the Doctors large blue box came into view.

"There it is!" the Doctor cried out happily, "Oh, I am so happy to see you old girl! Just a snap of my fingers and…." The Doctor looked down at his hooves and growled. "Blast these hooves! Ok, Cherry Tart! New plan! Lead the Jallpurian off that way, while I get the TARDIS open!"

"Got it!" Pinkie called back and took off away from the TARDIS as the Doctor dove behind some trees. The Jallpurian, seeing only one pony, followed after Pinkie. Seeing the creature going away, the Doctor stepped back out and walked up to the TARDIS. Reaching into his saddlebag, he pulled out a small gold key and quickly unlocked the door.

"Okay! It's open now!" he shouted towards Pinkie, "Lead it back this way!"

Pinkie and the Jallpurian came running back, headed straight for the now open door. Pinkie rushed inside, and the Doctor quickly dove in after her, shutting the door. The Jallpurian kept running and slammed into the TARDIS, causing the whole thing to shake.

Inside, the two ponies lay on the floor, out of breath and breathing heavily.

"Well… That was close," the Doctor panted, standing up, "We're safe now. Anyway, Coffee Cake, welcome… To the TARDIS."

Standing up, Pinkie looked around the impossibly large room, eyes wide. "Whoa…" she said, "The inside is… and the outside is… Oh! I get it!"

"I – What?" the Doctor asked, confused.

"The inside isn't really the inside. Because there isn't an inside. The outside is just a door and this is somewhere else."

"Yes… That's right. How did you…?"

"It's super easy to see when you don't think about it," she replied matter-of-factly.

"My God…" the Doctor mumbled after a moment, "Did anyone ever tell you that you are brilliant?"

Pinkie shook her head. "Most ponies just think I'm crazy."

"That's not such a bad thing. Most geniuses are a little bit crazy. Just look at me."

Pinkie giggled and said, "So what do we about the jelly bean thing Mr. Genius?"

"Well, we need to get in here, but as it is right now, it'll eat us on sight, so we need some way to make sure that doesn't happen."

"We could wait until it falls asleep."

The Doctor shook his head. "Jallpurians don't sleep. It's one of the things that makes them so dangerous."

"Is there some way we could, like knock it out?"

"Knock it out? Oh Bubble Berry! You are a genius!" the Doctor exclaimed, "Yes! Oh, silly Doctor! Why didn't I think of that before?"

"It's Pinkie Pie," the pink pony responded, "And why am I a genius this time?"

"Because there is a way to knock out the Jallpurian. With strawberries."

"Strawberries?"

"Strawberries," the Doctor nodded, looking a little smug, "They grow all over the universe. A rather universal fruit, if you will. And of all the things in the universe that they can eat, Jallpurians love strawberries most of all. However, they almost never eat them."

"Why not?"

"Because if they do, it causes them to fall unconscious for about twelve hours. No idea why. It just happens. I think it's some kind of allergy."

"So if we can make the jalopy eat some strawberries, then we can get it in here safely."

"Exactly! And I do believe that I have some strawberries in the kitchen. If you'll wait here for just a moment, I'll be right back."

The Doctor rushed off into another part of the TARDIS, leaving the pink pony sitting alone. Then, from where he ran off to came a clattering sound and the Doctors voice, saying, "No. No, not that either. Ew, no! Gah, how long has that been in there? Definitely not that. Ah ha! There you are!"

The Doctor came walking back out with a small plastic bag of strawberries in his mouth and set it down in front of Pinkie, smiling.

"Hurray! Strawberries!" Pinkie exclaimed jumping into the air.

"Indeed. Now we just need to get these to the Jallpurian."

"How are we gonna do that?"

"Simple Cheese Cake. We throw it outside."

"But if we do that, won't the jabally thing get in here? And my names Pinkie Pie."

"Not if we time things just right. Come on," the Doctor said, ignoring Pinkies last statement and walking over to the console. He set to work pressing buttons and pulling levers, and a screen dropped down, showing the Jallpurian outside, pacing around, and then ramming into the TARDIS, causing the room to shake. "With this," the Doctor smiled, "We can watch it and time things out just right. Now then, you stand here and watch the screen. I'm gonna go stand by the door, and when you see the Jallpurian move back, tell me so that I can throw the strawberries outside."

"Okie Doki Loki!" Pinkie replied with a salute and stood in front of the screen as the Doctor took his place by the door. Pinkie watched the screen, starring intently at the creature mulling about outside. Then, as it began to move backwards, Pinkie called out, "Now!"

"Right! Take this Jallpurian!" the Doctor shouted opening the door and throwing the bag of strawberries outside.

On the screen, the two of them could see the Jallpurian stop and look down at the bag, confused. It bent its head down and sniffed at the bag, then snapped it up, quickly swallowing it whole. It prepared to ram into the TARDIS again, then stopped, stumbling groggily and than fell over.

"Yes! We did it!" the Doctor exclaimed, punching a hoof in the air, "Ha ha! Even with hooves, I've still got it!"

"Hurray!" Pinkie exclaimed as well, doing a back flip.

"Now then, lets get that alien predator on board."

It was a little difficult, with how much the Jallpurian weighed, but the two ponies were able to get it into the TARDIS. With the unconscious creature now safely inside the Doctors strange blue box, the two stood outside.

"Well, this has certainly been an interesting day," the brown pony said.

"I know!" Pinkie bounced up and down, "I've never had so much fun in all of my life! You may be a little crazy, but you sure know how to have a good time!"

"Thank you. Now then, there's one last thing I need you to do."

"Sure thing! What is it?"

"I'm gonna take the Jallpurian to a different planet, and I want you to stay here, alright? I'll be back in moment, so just stay here. Okay?"

"Got it," Pinkie responded with a nod.

"Good," the Doctor smiled and walked back into the TARDIS. With in a few seconds, the blue box started to make a soft whooshing sound and began fading into invisibleness. Within a matter of seconds, it was gone. Pinkie simply stood there, staring with wide eyes, mouth hanging open, struck speechless for the first time in her life. Then, only a few seconds later, the whooshing returned and the TARDIS reappeared. The door opened and the Doctor stepped back out. "There. All done," he said.

Pinkie stared at him, still speechless. It took her a moment, but eventually, she found her voice again. "Wow," was all she could say.

"Indeed. Now then, while I was away, I took a little bit of time to see why I ended up here. Seems a freak wormhole opened up around the TARDIS while I was trying to reach London and funneled me here. I was able to lock onto what I think is that same wormhole, and I'm pretty sure I can use it to get back to my world. So, with that said, I just want to say, thank you for all your help today Pinkie Pie."

"You… You got my name right."

"Oh, have I been saying it wrong? Dreadfully sorry. Anyway, once again, thank you. This is good-bye. May we somehow meet again in the future."

"Good-bye Doctor," Pinkie replied with a sad smile as the brown pony stepped back into the TARDIS. With a whoosh, the TARDIS faded away and Pinkie was left alone in the clearing. "I'm gonna miss him," she said and began walking back towards town. She suddenly stopped, hearing a familiar whoosh coming from behind her. Turning, she saw the TARDIS reappear.

The door opened and the Doctor stepped out and with a smile said, "Hello, London! It's good to be… Right where I was. What? How is this even…?"

"Doctor!" Pinkie exclaimed, rushing forward and pulled the brown pony into a tight embrace.

"Pinkie? What are you doing here? Have you just been hanging around here this whole time?"

"Huh? What do you mean? You've only been gone for a few seconds."

"Wait, really?" the Doctor asked, pulling himself out of Pinkie's hug.

Pinkie nodded. "What happened you to going back to your own world?

"I don't know," the brown pony said confusedly, "I thought for sure I was headed home, but apparently, whatever I locked onto wasn't a wormhole. I'm starting to think it was just an empty part of space…" the Doctor trailed off, look away, lost in thought.

"So, what now?" Pinkie said after a moment, pulling the Doctor away from his thoughts.

"Hmm? Oh, well, I guess I go exploring. This is a whole new universe for me, completely different from my own. I would rather like to see it. And, I could use a companion."

"You want me to come with you to see the universe?" Pinkie said incredulously.

The Doctor nodded. "Not just the universe. The TARDIS, my wonderful, beautiful machine, can travel, not just through space, but also through time. So you see Pinkie, if you come with me, we won't just be traveling to planets and places you've never heard of, we'll also be traveling into your past and future! So, what do you Pinkie Pie? Want to come along? Pinkie Pie?"

The Doctor looked around the clearing, and could see no sign of the pink mare. "Pinkie?" he called out, "Pinkie, where are you?"

"Come on Doctor! We're wasting time!" Pinkie's voice called out from within the TARDIS.

The Doctor turned to look at the blue box and chuckled. "Well, I guess that's a yes."

Thanks for reading, and be sure to leave a nice review!
