The Doctor blinked. Bright Eyes was amazing. He'd never seen such speed and strength displayed at the same time.
"Ditzy, stay back, we don't know if this thing's dead or not," he said, trotting forward to examine the bulk. It had the shape of a regular pony (assuming that the Doctor was a regular pony), all except the head. Rather than a mane, atop the head was a metal rod, not unlike a bucket handle, connecting the ears. A cyberman- cyberpony, really.
"How do you exist even here? Do you survive just to 'Delete' anything different?" he questioned the metal hull. His eyes raked the body, taking in every scratch and dent in the metal, every pattern and hole in it. "Style never changes, does it?" He asked himself. Sighing slightly to himself, he sat on his hind legs and pulled the sonic screwdriver out of its place in his saddlebags with little grace. Adjusting the settings with his teeth, he pointed it directly at the chestplate of the cyberpony, a cybus industries logo, and fired. With its usual whirring noise, the screwdriver came to life and lit the plate with a blue glow. With a bit of clanking noises, he began to struggle to open the plate.
"Hooves. Very difficult." He mumbled, still trying to get the piece out. Eventually, he had managed to press on side of it in, exposing the rim just an inch or so. Using his teeth, he gripped the flat circle and gave a sharp tug. The plate gave way, but the doctor quickly spat out the piece, it was still burning hot and had a horrible chemical taste besides. Turning back to the cyberpony, he knelt down and examined the interior. It seemed to be the same as Cybus's 'upgrade' back in his own dimension, complete with a rather disgusting layer of artificial nerve tissue. Shifting the sticky and slimy matter, he soon found what he was searching for inside the pony's chest: an infostamp.
"Doctor, what's that? A robot?" Asked Ditzy from behind him. Turning around, he had to think for a moment before he replied.
"A cyberpony. And it's not a robot, not entirely. This thing used to be a living pony, until it was 'upgraded' to... that." He said, poring over the cylinder in his hooves. "They took his- or her- brain out and, took away its emotions ad put into the machine, bulletproof and nearly indestructible. A near-perfect soldier." He mused. A look of sickened horror crossed Ditzy's face. The Doctor shot her a knowing glance before going back to fiddling with the infostamp. Within a moment, the thing came to life, projecting images... right into the Doctor's eyes. With an "ack!" of surprise, he set the thing in the snow-covered ground and allowed it to project on the side of a rock face nearby.
Ditzy clearly understood none of it, but the Doctor felt he had struck gold. Flashes of a factory, maps, coordinates, even a few videos of Cybus himself- the Doctor had to snort at his appearance in pony form. "Come on, Ditzy," He began, "We're going to save a planet!" He began trotting off towards the coordinates in the cyberpony's infostamp. Ditzy didn't follow.
"Does that mean there are more of them? More cyberponies?" She asked, concern clear in her skewed eyes.
"Yes, and we're going to stop them, Allons-y!" He turned back around and galloped towards the coordinates.
"But you said they were ponies... like me." She said, still steeled in place. The Doctor sighed and turned around. Morality issues, wonderful.
"I know what you're thinking. I've felt that way too. But they're not people. They haven't been since they were turned into cyberponies. There's nothing we would be able to do for them anyways, they're only soldiers now." He explained. Ditzy took a few tentative steps forward before stopping again. The Doctor groaned inwardly.
"But you said they were indestructible. How will we stop them then?"
"I said nearly indestructible. And I'll stop them like I usually do; with a lot of running and explosions. Well, a lot of flying in your case." He said. Thankfully, this seemed to convince Ditzy and the two strode off at a powerful pace towards what the Doctor suspected to be primary Cyberpony plant.
The Doctor could sense they were growing closer to the plant. The sky was ever so slightly darker, and there was the subtlest hint of sulfury chemical smell in the air. Ditzy seemed to notice too, as she shot him a glance. Minutes later, they arrived at a tall chain-link fence, surrounding the compound at a distance. From his vantage point, the Doctor could see the Cyberponies as little more than marching specks in the distance, but the Cybus Industries logo was clear as day on some of the large towers inside the fence.
"Ah, here we are... now how to get inside.." He said, rubbing his furry chin with a hoof. Beside him, Ditzy snickered. Glancing at the gray mare, the Doctor was caught by surprise as she launched herself at him, wrapping all four legs around his chest and flanks. He realized what was happening a moment later, and cut off his screaming protest. Ditzy was lifting him, higher and higher, over the incredibly tall chain fence. Reaching the top, the Doctor noticed a watch light nearing them with great dismay.
The Doctor's hearts pounded in his chest as the searchlight drew nearer and nearer. Keeping his face clear, he prepared for the worst. Who knew if the cyberponies in this dimension had guns or not? But to his great shock, and admittedly terror, he suddenly felt air whooshing past his face. Opening his eyes, he'd seen that Ditzy had dropped him, and tightly shut them again. The ground was racing up to meet him as the light passed inches above him. But the second it passed, the pegasus was racing much faster than the ground and caught him moments before what would have been a very messy end to their short adventure. As the mare dropped him off and landed next to him, he quickly shut his jaw and cleared the terrified expression of his face.
"Ditzy, warn me next time you're going to do something like that!" He exclaimed. Ditzy replied merely by sticking her tongue out. The Doctor sighed, amused now rather than mortified. "Did they see you?" He asked her.
"Yup!" She said brightly.
"We have to get out of here then, they'll have us swarmed in seconds!" The Doctor said.
"I don't think so." Said Ditzy. "They didn't notice anything odd about me, not from their distance." Realization struck the doctor.
"Ditzy that's brilliant! That's- that's downright genius!" He exclaimed. She truly was much sharper than she looked. Using a gray coat as camouflage in an army of iron, incredible! The Doctor quickly turned and began trotting towards the main compound, but Ditzy blocked him before he had gone so much as five feet.
"From now on," She began, "I lead."
