Sunset Shimmer the Doctor's Companion.

"Doctor, are you alright?" Sunset Shimmer gawked, astounded at the Doctor's sudden comment.

"He's fine, he just regenerated," River explained. "that's the timelord's way to dodge death."

The Doctor snaked his lips and requested, "I'm hungry... Give me apples, I love them," before falling unconscious.

"Where can we find apples around here?" River asked the group.

Sunset, taking advantage of her former knowledge of the Equus's streets answered River with another question. "The TARDIS can move in the same universe like an aircraft, right?" At River's nod, Sunset told her to move one hundred and fifty kilometres south before explaining, "You can find lots of apples for the Doctor in the orchard over there."

Sunset and the rest minus the Doctor and River left the TARDIS. Then River and the Doctor took off with three whooshes as the TARDIS flew south.

On the TARDIS, River followed Sunset's instructions, so in no time both were there.

Right then a sound like a cloister bell was heard. "ohSHIIIT!!!!"

The TARDIS crashed through Sweet Apple Acres threshold, cracking the wooden structure, splinters flew everywhere. The TARDIS barely managed to land.

River left the TARDIS and walked into the orchard. She saw a pony with a Stetson hat, and without a word, she just took a bushel of apples. She dragged it with her teeth into the TARDIS. The farm pony's reaction was quick.

"Wretched vermin! Stealing from me right under mah' snout!" Applejack called out for Big Macintosh, her stoic brother. But before he could arrive, River closed the TARDIS door, a door not even the Genghis Kahn's troops could trespass.

Once inside the TARDIS, River rubbed a nice looking apple under the Doctor's snout. The Doctor opened his eyes, and after a whiff of the apple, he bit it. He chewed it for a moment before spitting it back out. "What's the idea, River? Trying to kill me again? God, it's horrible!"

"Doctor, are you with the living now?"

The Doctor, holding the apple said, “Uh? Yes, I'm fine as rain. Also, where's Sunset?”

"Still in Canterlot," River answered.

“Do you think he'll be alright?" Sunset asked Celestia worriedly.

“He'll be alright, Sunset," Celestia answered with no doubt.

The Doctor was feeling alright at the moment and opened the TARDIS door. He was suddenly confronted by a pony wearing a cowpony hat.

“Hi, Ah ahm the landlord. Ah came to evict ya'll...” the farm pony explained with a no-nonsense look on her face.

The Doctor happily smiled at her. “Hi, I'm the timelord!”

The mare in the hat said, “This is mah brother, Big Macintosh and Ah'm sure he'd love to talk to the likes of ya.”

Big Macintosh introduced himself with a dry “Eeyup", but the Doctor was oblivious at the danger at hoof.

“Fancy a jelly baby, big guy?”

Back in Canterlot, Sunset was chatting with Celestia, oblivious at what was happening one hundred and fifty kilometers south. “And this is Twolight, the soul sister of Twilight.”

Celestia then asked Twolight. “What do you think of our fair Equestria so far?”

“Actually, it's very exciting, how everything is so alike, yet so different...”

An explosion was heard coming from Sweet Apple Acres. A few seconds later, the TARDIS quickly flew into a Canterlot, some apple tree debris hanging onto it.

The machine landed on the same general spot where it took off previously. When the door opened, a conversation could be heard, crude words included.

"Who'd know that jelly babies are made from hooves? And how do ponies know that?"

"I don't think they wanted to destroy you for that, dearie. Not exactly..."

“Any ways, that Applesnack is the worst!”

River, commented. “Come on, she's not that bad...”

The Doctor quipped back, "Yes, she's all comfort and joy. The problem is her brother. He kicked my TARDIS!" the Doctor went over and patted his damaged vehicle.

"Ya, that pony's a horrible bully! We don't want to be around him any-more."

Amazed at the poor show Applejack made, Celestia offered the group to be guests to her palace. "I'll even send some guards to keep an eye on the Doctor's machine. I can even send some of my craftsponies to repair the woodwork damage."

The Doctor accepted the princess's offer. "Thank you, my princess," he said as he reached down and kissed Celestia's hoof, causing the sun princess to blush.

An hour later, the group was in the castle. Some guards arrived to pick the TARDIS. Tremorhoof, one of the guards, was busy supervising the other guards as they loaded the TARDIS onto the wagon. Then, the TARDIS door opened, a tiny silver robot with crimson eyes left the TARDIS.

Seeing this, Tremorhoof told his companion, who was pulling a heavy cart, "Did you see that, Jeff?"

"Yes. For being a doctor, he doesn't care much for a clean and rat less environment."

Meanwhile, the 'rat', or rather, cyber-rat, got into a sewer. It followed it's program to search for and collect resources to fulfil it's mission. It had enough technology for a basic lab, one bigger on the inside thanks to timelord technology, and it had a sinister agenda.

Restoration of the cybermen.

In a dark, damp crook in Canterlot’s sewer network, a newly built technological nightmare stood. A cacophony of metal on metal grinding permeating the place as a creature, not of flesh and blood, but of metal and circuitry, stood at a console.

Phase 1........ Complete.

Phase 2 .... In progress.

Meanwhile in Ponyville:

A Grey Filly was enjoying the Summer morning. It was, oddly enough, warm for a day of Selenic. Being “Selenic” two whole months before Summer Sun Celebration, she was busy chasing butterflies, a shameful secret of hers, when she heard a rustling noise coming from the stream besides the Ponyville public park. She, being cautious, pranced careful towards the weird noise, it was a noise like the one a small rodent would make, but odd mechanical noises followed behind it.

When she reached the bushes and took a look the many birds in the trees took flight at the sound of the filly's blood curdling scream.

Back in Canterlot.

Sunset was busy explaining to Twolight how to use the equus sanitation devices, after explaining for nth time how to use the three seashells, she decided she had enough.

“Alright! Be a cavemare! Melody, care to explain it to her?”

“You know we can put a biggie on her. Just a suggestion...”

Twolight, genuinely offended, suggested River/Melody to just lick her tush clean. Thankfully, however, Shimmy defused the situation before any blood could be spilled. “Toilet humour is a staple of Equus-beta... Remember it Melody, I am telling you the truth.”

“All right, let’s say that I believe you.” Commented the still uneasy, curly maned mare.

Later, the crew plus the princesses were reunited for lunch on the palace main hall.

Celestia lead the table, while Luna sat at her left. Before them sat our crew, Sunset, Flash and the Doctor had the centre, Flash stood at Flash the guard.

“Incredible... You’re so me, but not... Tell me, if I kill you, I become you?” Flash Sentry (The guard) stood uneasy, he stared at Celestia, worried. Celestia opted to release him.

“You can leave...”

He left the hall galloping. Quickly, Celestia glanced at Sunset in disapproval.

“Well Princess, love can’t be planned...” Meanwhile Melody approached to the Doctor.

At this, Luna promptly awoke from the nap that she had apparently been in during the meeting. “Sister I FELT IT! WE ARE IN A...”

Celestia simply sipped on her tea calmly “Sister, indoor voice.”

“We are in grave peril, when I fell asleep, I contacted with a filly, she’s in distress...”

“How in distress?  Share with me your dream.”

Luna’s eyes became white, her horn glowing in a blue light. Celestia followed suit, leaving the rest of the ponies looking at them in unease. That unease soon became horror at the sound   of Celestia screaming and falling to the floor.

“I-It’s horrible!” Celestia was sobbing now “How it can be? She’s feeling a terrible pain! She's from Ponyville... just a filly... ”

Sunset grinned at her former mentor. “All right, so, she’s in Ponyville.”

“No... NO. She was in Ponyville, I see that she was dragged over waste, she’s near, so near, she can’t see, she has sand on her eyes...”  Celestia was out before she could finish. Sunset felt her for pulse.

“She’s just too empathic, got overstressed. She'll be fine...” Sunset then stared to Luna “so Princess, are you going to share any usable info before knocking yourself out?”

“Likely, it was a dark place, with water and waste, but there was no currents there.”

Sunset was pondering on that “A pond of some sort... It was dark, so it was on a forest, or...”

“It was a place made with masonry, if that helps.” Added Luna.

Twolight added her two cents “Water, masonry, waste... Tell me princess, are there are sewers around here?” Luna dawned in realization... “Of course! The Sewage System! In fact I designed it a thousand years ago!”

“Then tell us about the current-less parts...”

“A sewer can’t have any part like that, but back then were many cave ins. We lost many artisans, mainly on the lower sector, but that sector is twenty square miles of area...”

“We can do it...” Sunset Shimmer decided, “...we have to.”

Later, in the entrance to the Sewer System.

Sunset was rallying her ‘troops’ “You guys learnt and understood the basic light spell? It's dark down there...”

Twolight, Melody, and Shimmy gave their confirmations in one voice. The Doctor gave his response by turning his Sonic Screwdriver on.

As this happened, Flash look over them before turning to Sunset, “I am no Unicorn...”

Sunset gave him a look, “You can’t do anything now, you go to our rooms and wait for us.”

“I don't feel like that is a good idea, what if you don't come back?”

Sunset smiled at that and gave him a kiss. Before the pegasus could say anything, however, Sunset gave him a little jab with her horn and cast a sleep spell on him. She caught him before he hit the ground and passed him to Celestia with her magic, “Take good care of him.”

The Sun monarch replied at her “And you take care of yourselves, please come back safely.”

Sunset looked at the sewer entrance, charging her horn with both a heavy blast and a light spell, a ‘mixed salad’ like she liked to refer to it. “This is it! Just like on the essays!”

Sunset, Twolight, Shimmy, Melody and the Doctor, five little ponies that ripped a few new ones on the universe, ran shouting to the bowels of the unknown, all of them screaming a war cry at the top of their lungs.

Twolight, who memorized the sewer plans, called to the rest were to go when confronted with multiple turns, “Left then the next is the middle one!”

It wasn't long before Sunset spoke up, “Stop! You guys hear that?” There was a mechanical hum,

“Machines.” Commented the Doctor “but it can’t be, they disappeared long ago...”

“Who disappeared, Doctor?”

“Uh? Who said that? It was you Shimmy?”

“Nope, not me...”

“Aren’t you a cute widdle group of blankflanks? And you who do you think you are with those wings and that Sun Cutie Mark? Celestia 2.0?”

They all turned to see a creature moving towards them. It was made of metal, barely equinoid in shape, but it lacked tail and mane and had a thick metal tube connecting both it’s earlobes, the metal tube at the centre had a spotlight that shone a bright yellow light.

Both Sunset and Twolight felt their jaws drop. Twolight whirled around to face the Doctor,  “What IS that thing?”

Melody replied “I think it’s a Cyberman? CyberHorse?... hun?”

The Doctor was busy preparing his Scredriver, attuning it to the CyberHorse frequency. With a grunt of approval, he raised the tool to the mechanical pony and clicked a button. The effect on the robot took Sunset by surprise, as it simply froze. She was about to comment when the face plate of it moved and revealed a grey, scared, earth pony filly.

“Please help me! Oh please please please! By Celestia you can’t leave me here!” She tried bringing her forehooves together in a desperate attempt to plead, but because her body was frozen, she looked down on them and began to realize how far she had changed “Oh my... Celestia help me!”

Sunset, now, near of her breaking point, turned yet again to the Doctor, “Please, tell me you can do something...”

“Oh yes, I can give her peace of spirit... Please, stay put, it will just take a moment and everything should be fine...” Upon hearing that, the filly began bawling for her mother.

Sunset, pissed at the Doctor, shouted at him “So, that’s your general idea? Kill her? Yes, she’s smelly, ugly and has a grating voice but you can’t do that!”

That quickly got the grey filly to go quiet and with a deadpan look, she moved her eyes to the fiery red maned mare, “Uh, Thanks,”

“Alright Sunset, what if we don’t do that? Back on the TARDIS I have a thing that can help us, perhaps...”

Sunset decided to let the Doctor's actions slide. For now. “How do you think we should proceed in a way that doesn't take us out of the sewers?”

“Easy, this place is chock-full of Timelord and Cybermen technology, add this to my utter awesomeness and we can have ‘Stinky’ prancing and bullying in no time! By the way I find the name ‘Cybermen’ kinda grating... Cybermare? Yes, that can work.”

“Doctor, I’ll have to introduce you to Pinkie Pie sometime...” Sunset commented, trying to get her head straight after the last mouthful by the Doctor.

“Pinkie? As in Pinkamena Diane Pie? Already met her two thousand years ago, we had a blast, but I still have no idea how she ended up inside the Time Rotor...”

Sunset smiled at that “Heh, same old Pinkie...”

The Doctor had already got into sorting parts for the conversion machine, when a proper Cyberman appeared, his two feet clanking over the masonry floor. it spoke with a raspy metallic undertone, “we can use more subjects for mandatory update.”

Shimmy gave the Doctor a look, “Update?”

“They turn you into that metallic thing, willing or not.”

“Hey! What do you think I am, chopped oatmeal?” shouted Silver Spoon inside her metallic husk, that was now once more under direct control of the Cybermare factory
