MEME WHILE IN CANTERLOT
(Don't leave this is a serious chapter that I'm disguising with memes)

Dr. Tygan covered his head as the whole lab shook. Alarms went off, and the emergency lights came on meaning they lost central power. One of the assistants tried the Comm console.

"Whats going on!" The young curly brown-haired man asked. A security chief answered.

"The base has been hit,... No, No that can't be possible not here!" The last thing heard before horrified screams was a sound that was unmistakable a Chryssalid screech. Tygan's blood went cold. Old enemies could only mean the Elders were near. There was a telltale skittering that shook him from his fear.

"Lockdown the doors hurry!" He pointed, and the Lab Tech bolted and slammed the emergency button. Solid steel doors slammed shut; the tech looked at the doctor who nodded his approval. Dr. Tygan heard a whimpering from underneath the table next to him. He crouched down to look at the little yellow unicorn hiding with her hooves over her eyes shaking badly.

"OH, Celestia it's the changings all over again. I DON'T WANT TO DIE!" She wailed

"Miss Tess, panicking isn't going to help anyone. Please remain calm X-Com is very familiar with these creatures." The doctor spoke calmly, and Tess Tube relaxed seeing his composure. There was a rumble in the vents, and Tygan felt his words turn back on him. One of the vents burst open with the dark purple and orange chitinous armor of a Chryssalid, the quadrupedal insect the size of a full grown man barrelled towards them with a haunting screech. Tygan threw himself to cover the pony squeezing his eyes tight.

He felt something fly past him and turned to see a table was thrown knocking the alien back. Followed by bright flashes of orange and the sound of plasma rounds. With each shot, a limb flew off. When the creature fell, a man raced over and brought his bronze boot down hard enough to make the floor shake. He kept stomping the dead alien as if it owed him money (or Ammo) Finally the man in armor made of bronze strips of copper stood up straight breathing heavily his helmet cast three stripes of blue light.

Tygan scanned the room seeing the tech under a vent. "Brent get, away from the ven-"Too late another monstrous Chryssalid burst down and took the man to the ground. The bronze man aimed his small pistol like tool with three laser dots shining where they had fallen behind a lab table. The screams ended in a gurgle then silence. The man edged closer keeping his cutter trained on the table. His patience paid off when the creature popped screeching. Its head flew off with a discharge of orange plasma. Everyone heard the rest of the body fall with a boneless thump.

Nobody breathed when an almost human groan came out of the now standing tech. Before Tygan would warn of the undead Tech the man was already firing an arm went flying, and the rest of it rushed over the table in a crazed dash. Another shot and it's leg came off in a spray of blood sending the undead tech to the floor. The man rushed in and stomped sending blood splattering. Causing Tygan to cover his eyes from the carnage. The man started cursing violently and hysterically. Tess began to sob hiding her face from the scene.

When the corpse was little more than bloody mush, the man finally calmed down. His shoulders heaved, and the helmet retracted from his face revealing a middle-aged man with a five o'clock shadow. He ran a gloved hand through his short brown hair.

"Are you ok Mr. Clarke?" Tygan asked shaking the blood from his hand.

"Ya." Clarke swallowed and nodded his head "Ya I'm good." His Helmet unfolded back over his face, and he turned to look at the Doctor.

"I will say, Mr. Clarke, I had forgotten you were in here for maintenance. Thankfully you were, this encounter would have been slightly more unpleasant without you." Tygan said calm as always.

Isaac Clarke snorted shaking his head at the Doctors deminer.
"I Bet. Doc what the hell are these things?"

Tygan furrowed his brow. But Isaac moved his hand, and a blue energy field shimmered around it and reached out to pick up another table. "Short answer Doc." He let out bluntly, and Tygan huffed. He floated the table to the ceiling over the busted vent and pulled out a different tool and began bolting it to the roof. As Tygan begun to explain,

"In short insectoid creatures that poison and lay eggs in their victims. Causing reanimation before a new full-sized creature burst out." Clarke finished and moved to the next,

"Giant bugs that reproduce through zombies got it." Clarke summed up grimly and inspected his work. He put away the tool and begun to check over several other tools while muttering to himself. "Ok, Clarke you've dealt with worse things. What your Oh for Four on eldrich horrors in my life?" He shook his head. "Ok here's what your gonna do. Your going to open these door then shut them till I come back stay quiet. I'm going to look for other survivors."

Tygan grimaced "X-Com personal are well trained and experienced with these aliens Mr. Clarke." Clarke looked at him

"That's what Earth Gov said." Isaac moved to the door, Tygan rushed over to the override button clearly against this idea, But unable to convince him otherwise.

"Be careful Mr. Clarke There are guaranteed to be more intelligent and armed units wondering the halls," Tygan warned, and Isaac nodded before the door opened and he stepped out. Their eyes met before the Doctor closed the blast doors again.

Isaac swept the hall with his trusty plasma cutter. He heard a familiar song creep into his ear like someone was whispering it into his right ear. A familiar tingle in the back of his skull like a hand brushing his hair. He ignored it because if he acknowledged it, it would only make her worse. He focused on the noise around him trying to ground himself in the fucked up reality that was his life.

"Come to the pony world they said... Join X-Com they need Engineers they said. Protect the cute candy colored ponies from bad guys..." He paused and tilted his head "Ok at least that ones true." He admitted Their was a loud explosion from down the hall and blaster fire. He altered his course and started towards the sound. "Oh ya and the small legion of perfect clone soldiers with plasma weapons more advanced then anything I've seen. God who knew you could shock point to another universe.." He finished muttering as he rounded a corner to see three aliens with green armor dead while blue bolts kept hitting the wall.

He could hear a female yelling angrily. He recognized that kind of yell, someone desperate to survive. The blue bolts stopped hitting the wall, and he approached slowly. He could hear the clicking of an empty gun. The yelling stopped, and he poked his head into the entryway only to meet eyes with an Orange mare with hay colored hair and green eyes.

He watched her eyes flick to a dead clone with a hole burned through him. She rushed it reaching out for a round thing in the corpse's hand. He tried to yell wait, but she didn't hear. Throwing his hand out with a blast of stasis that bathed the mare in a cold blue and slowed her to a crawl. Isaac breathed a sigh of relief and approached her. Her eyes moved to him slowly fear clear as day on her face. He crouched and pulled out the little I.D card X-Com had given him. Slowly she read the I.D and panic left her face as the stasis ended. He caught her before she could plow headfirst into the dead clone.

"Woah nelly." She let out disoriented by the sudden shift to normal speed. Her accent was thick and southern.

"You ok?" He asked, and she nodded shaking off the stasis effects.

"Sorry for almost chucking a det at your face." She apologized, and Isaac looked back at the pile of aliens, and the exploded doorway.

"Judging by the hall, I'd say you'd be forgiven for kneejerking." He assured before standing up again. "Got a barricaded room a hall down you'll be safe there." He hooked a thumb over his shoulder, and she nodded.

"Alright, Tinman just let me grab something." She said warily before approaching the Clone he heard her say something like "Sorry Twenty-five" Before working the belt off the clone as gingerly as she could. He offered a hand when she looked like she was having trouble getting the belt around her waist. She hastily declined, flopping on her back to clip the belt around her barrel. She retrieved the Clones rifle and slung it over her back adjusting the strap till it didn't drag anymore. She looked back at the clone one last time

"I'll plant the biggest tree for ya Twenty-Five." She looked back at Isaac with determined but wet eyes. "Let's get going then." Isaac nodded, and they left the scene.
