Darkness, that's all the biological and technological eyes respectively could see. This drone had abruptly been separated from its hivemind. It no longer received signals from any communication servers. It's as if the entire ship had disappeared around the unit. Impossible, moments ago they were using the emergency time module to escape from:

Faction: United Federation of Planets (Hostile)
Species: Mixed/Human
Assimilation Priority: 152 of 592265

It felt a sense of falling. It engaged its motor functions, moving to the calculated squatting position to void any damage caused by a minor fall. But the drop ended without an impact. The unit's eyes were met with light that would have blinded a normal bipedal lifeform. The eyes of the drone were set to a lower brightness. Subsystem scans brought data of surroundings indicating a oxygen and pollen rich atmosphere.

The drone quickly scanned it's eyes left and right. Seeing nothing but green fields. As it turned an almost 60 degree angle to the right it saw a large city carved into a mountain, the sun shining off the majestic towers and wall. It then had another though process. Coming up short of any known human architecture it reasoned that its location could not possibly be earth unless they had descended into the dark ages...Or it was sent back far enough into earths history that it was at an advantage.

>Immediate Concealment program deactivated

It walked toward the great city. It's eye zoom only reaching a low X4, unable to see any activity besides objects circling and moving this way and that. Registering them as a bird of some kind long extinct or unknown.

However as it grew closer to the city it saw something quite...Unexpected.

>Horse
>Negative, Pony
>Pony with wings
>Subspecies unknown...Documenting
>Pony Species 13-1

But before it could further add data to it's new folder it was surprised to see a horned pony on the wall in heavy golden armor. It had not noticed it at this distance and appeared to be levitating a small apple next to it's mouth.

>Pony Species 14-1
>Metal Armor - Thick
>Levitation technology, attempting to assimilate...
>Unable to assimilate without nanotechnology contact

It moved at a high walking speed now, the ponies on the wall taking notice at the striding drone. "Is that there a diamond dog?" The unicorn asked to his earthpony partner on the wall. "Nnn-op, never seen one with abuncha hoses and green lights on it before." Before they could ponder further or raise some sort of alarm the drone had reached the wooden door reinforced with metal.

>Obstruction detected
>Designated as gate
>Activating energy weapon systems

Raising it's arm it shot a green beam into the door, it made a rather hissing noise as it sliced through the thick wood. It only took seconds but it had left a half oval in the doorway and was walking into the city. It stepped into the city, it found many large eyes and backward facing ears. Accompanied by some small gasps and sounds of hoof-beats as some fled at the strange creature. "Hold it!" The unicorn mare from the wall said as she charged down the stone steps from the wall, halting a car length from the strange creature. "You just broke into the royal city of Canterlot without permission from the guard or proper notification!" The drone looked at her.

"We are the Borg. We will add your biological and technological distinctiveness to our own. Your culture will adapt to service us. Resistance is futile." It said without missing a syllable. The ponies stared. "Hey look here you! Ain't no one gonna 'adapt' to whatever the heck y-" She was cut off by the drone stepping forward, reaching out its arm and grasping at her left foreleg with a strong grip. "Hey let go!"

She tried to free her leg from it's grip, but the harder she tried to escape it's iron grasp the more it applied pressure. The armor she wore on the leg began denting in as it enforced it's grip. "Let the buck go! Help!" A green and black rectangle of metal and circuits the size of a I-Phone erupted from her left cheek. Follow by various different parts and augmentations. "S-sto- so, hmmm." She fell limp, her body continuously gaining more parts as the drone leg go of it's grip. "Resistance is Futile."

This was followed by the surrounding guards who had been dumb struck quickly form a phalanx of spears on the street leading deeper into the city. "All citizens should get out of here!" An officer barked at the back before being cut off by feminine pony voice cutting the air.

>Brain function reboot successful
>Up-linking to surrounding drones

"Resistance is Futile." The new pony drone stood next to the original. Both moving to walk toward the phalanx. A brave guard threw a spear from behind the wall of armor and spears. It made a crunching sound as it entered the original drone. It fell to the ground, the spear had hit and penetrated the skull. It did not get back up.

"Yeah! See? All the strange magic it's using is useless!" Another guard threw the spear confidently at the pony drone.

>Wood and metal projectile has rendered drone No.1 deactivated
>Adapting shield matrix

It harmlessly bounced off of a green field that slashed into existence like a rock hitting a lake. The drone was only a few meters from the wall before its left eye was replaced by a large robotic eye, streaming out a red beam of light wherever it looked.

Author's Notes:

Yes, crossover. Like it or don't. I don't doubt it's been done before. But if you like it please comment, I plan on keeping this the only chapter unless I hear SOMETHING.
