They came from the Everfree

For the first time in a long while, Ponyville's psychiatric section of the hospital was operational, and used, by Fluttershy, Element of Kindness. The reason to this, is that upon going back to her cottage, she found the bloody corpses of three stallions, who used to bully her. "It will take long for her to recover." Said Nurse Redheart. "Fortunately, the princesses sent their best psychologists for her and posted their most competent guards around the town, mostly by the Everfree. We should be safe."

But Twilight didn't buy it. She saw one of her best friends collapse from mental trauma right in front of her. Whatever was coming next, it was bad. The townfolks were to be warned. So she asked Mayor Mare to hold a speech dedicated to self-defense, and the best hiding spots in one's sweet home. Mostly the latter actually, since almost nopony had any sort of fighting knowledge. It would be held in a couple of hours, just enough time to gather the entire town in one single place.

Meanwhile, in the Everfree forest, a loud voice could be heard, alongside repeated sounds of animals being struck with a blunt object and sent flying across the woods. "BUCK YOU ! BUCK YOU !" Said the ear breaking loud voice, between each punch. "GET BUCKED ! GET BUCKED !" He shouted once again, slamming his right forehoof in a cockatrice's face. "DON'T RUN ! DON'T RUN !" And yet they still tried to outrun the punching atrocity.

'Atrocity' wasn't really the appropriate term. The one responsible for the punching fest wasn't that much of a monster. He looked like a regular light blue Earth pony, except bigger. Way bigger. Almost the size of Princess Celestia. And he was wearing a bandana, and sunglasses. "WHERE THE BUCK AM I ?!" He screamed to a collapsed, nose bleeding bear. His stomach rumbled. "BRB 30 MINUTES I'M BUCKING HUNGRY !" He shouted one last time to a knocked out manticore, before going on his way.

After walking for a small while, he arrived at a small cottage, surrounded by armored horses. "HEY GUYSSSSSSSS !" He said, showing a miserable demonstration of calm and respect. "DO YOU WANT TO BUCK WITH CHOZO TOO ?!"

"... any questions ?" Asked Twilight Sparkle, who just finished her part of the speech. A single hoof was raised. "... yes ?"

"You mentioned hiding under the bed if a creature happened to enter your house. What guaranties that it won't check every single corner of the house, bed included ?" Asked a bunny toothed, glasses wearing young colt.

"Oh ... hum ... you see ..." tried Twilight, aware that she had no answer to that question. Right before she was going to admit it, a bruised royal guard came panting. 'Nice save' she thought. The guard whispered a thing or two in her ear. "Mmh hmm ... yes ... wait, what ?!"

The audience confusingly looked at her, waiting for her to say something. "P-ponyvillians ..." she said, looking for a way to announce this without causing panic. "Please return home, a creature was spotted near Fluttershy's cottage ..." commom gasp, "... and the royal guards weren't capable of stopping it, in fact ..." an armored stallion fell face first on stage. "... It, alone, was able to beat twenty guards up ... please, don't pa-"

Instead, they panicked. A lot.

ChoZo followed the path before him. He just beat sentient creatures up. It was way more satisfying than those mindless thingies at the forest, which couldn't beg properly for mercy. But ChoZo's hooves were never satisfied, so he looked for more wrestling partners. Or harmless victims, whichever sounds better.

He finally came to a small village, where a single open door closed. He looked around before walking to what seemed to be a mansion decorated with the emblem of a white cross on a red background, accompanied by heart shaped symbols.

Twilight saw the scene from the library. "Spike, he's going to the hospital ! What if he punches patients ?"

"You just survived a blade wielding butcher and you're afraid about a stallion beating ponies up ? Nah, I bet he's gonna turn them into zombies." This earned a both disgusted, annoyed and worried glare from Twilight. All in one look. "Come on, why not ?"

Meanwhile, ChoZo knocked on the hospital's front door. Just kidding, he completely obliterated it in a single buck. Inside, a bunch of ponies were gathered. Most of them had bandages. In fact, the only ones who didn't were a white coated mare and a big red coated stallion, the latter standing defensively in front of the former. ChoZo walked forward, each step increasing the terror of the many ponies gathered inside. When he was in front of the red coated stallion, he threw him aside with little effort, knocking him out. Then, he turned to the white coated one, wearing a hat with a red cross on it. He raised a hoof ...

... and pointed it directly at the mare, who closed her eyes in fear of the deadly hoof-hammer. "MEDIC !" Screamed ChoZo. "MEEEDIC !"

Nurse Redheart was confused. That giant of a stallion just threw Big Macintosh into a wall, then asked for help ? No ! She couldn't help ... maybe it would save the other ponies. "H-how may I h-help you ?" She said in an inaudible voice.

ChoZo leaned closer, and stopped right in front of her face. "BUCKING HEAL ME !"

Upon further, inspection, one could notice the giant freakin' spear stuck in the giant stallion's flank. 'He shouldn't even be alive ...' thought Redheart, staring intently at the bleeding skin. In fact, there was a long blood trail, coming from outside, ending in a small pool where the stallion stopped. "It-it will take time ... at least a month, to fully ... re-recover ..."

He frowned. It was it. She shouldn't have said that. She could already feel the terrible hoof making connection with her jaw. She was lost. ChoZo grabbed her instead, then shook her repeatidly in mid-air. "THEN GET BUCKING STARTED !"

Royal Guards were posted all around the hospital. Princess Celestia was quicker than ever, immediately answering Twilight's letter, and sending more guards to help the ones already here. Since there weren't many guards needed on the frontlines, Captain Shining Armor himself was aloud to spend some time in Ponyville. "What happened this time ?" He asked to the nearest guard.

"Sir, the creature calling itself Chozo took an entire hospital as hostage, sir." Firmly said the guard, not loosing sight of the building. "Sir, a stallion was able to escape, sir. His name is Big Macintosh, sir."

"He's one of Twily's friends' big brother. They say he's the strongest pony in town. Guards, stay there, I'm going in."

It was a dark room. The blinds ... were closed. As he walked in, Shining Armor felt a shiver going down his spine. Not because of the dark, but because of what he smelled. A civilian would feel confused, but he felt worried. He would recognise the scent amongst hundreds. It was the smell of blood. He used a bit of magic to make light. His doubts, if they ever existed, were confirmed : there was blood on the floor.

He resumed walking, following the blood trail. Something ... no, somepony was silently laughing. This was creepy. Too creepy. He kept on following the blood trail. Then, he heard something. A mass fell on the floor. Right behind him. He slowly, slowly turned around, to face ... the Element of Kindness. Her pupils were at their smallest, and she was grinning like a maniac. She slowly opened her mouth, then said, without breathing once "If Discord works to create love, then we must deploy a dispenser point deep bass with cupcakes !"

Somewhere in a parallel universe, a black coated pony wearing a red hat felt like somepony just used his non copyrighted work. Then, he resumed eating burritos.

Shining Armor blinked twice. This wasn't Fluttershy's personnality. In fact, she just spoke nonsense. He thought about it. What if this 'Chozo' could control other ponies' mind ? Was he next on the list ? No. There wasn't time. Mind controlling or not, he had to eliminate this threat. So he went on, leaving Fluttershy alone in the dark. At one point, the blood trail ended in a small pool, then went on. So did Shining Armor, soon arriving at a closed door, with lights turned on inside. The blood trail kept going under the door.

He slowly put a hoof on the doorknob, then heard screaming from inside. Loosing any form of hesitation he had, he slammed the door open ...

... to find a giant stallion, about the size of Princess Celestia, with a spear in his flank, a nurse desperately trying to take it off. "FOR BUCK'S SAKE CAN'T YOU GO FASTER ?!" Shouted the former to the latter, earning a faint weep from her.

Shining Armor decided to speak up. "Captain Shining armor of the royal army, madam and mister. I have to ask you both to leave this structure as soon as possible." They obviously weren't listening. "... I am serious, a dangerous being is on the loose. It calls itself 'Chozo', and it could be in this very room !"

Hearing that, the stallion turned around. "WHAT THE BUCK DO YOU BUCKING WANT FROM ME ?!" He screamed at the top of his lungs.

Shining Armor took a step back, then cleared his throat. "Should I understand that you are 'Chozo' ?"

"THAT'S ME. ARE YOU COMING TO HELP ? GOOD. I WANT TWO BUCKING MEDICS FOR ME AT ALL BUCKING TIM- GAAAAH !"

"The spear's out ..." said sheepishly Nurse Redheart. "But ... s-sir, you are now bleeding profusely ! You need immediate medical assistance !"

Indeed, one pony alone surprisingly held so much blood in himself. ChoZo tried to mutter a single 'buck', but he couldn't, and simply collapsed from blood loss. Captain Shining Armor then even surprised himself. He used a lot of magic to sustain the collapsed giant. He then took Redheart, the patients, and, with much more effort, Fluttershy, out of the hospital. He called actual medics amongst his guards, and, with their help, succesfully stabilised ChoZo's state. He ordered the doctors to leave, then decided to try a conversation with this "Chozo".

"You're awake." He began. "Before you start screaming at me, I have one question to you : did you, or did you not cause the death of one or multiple ponies ?"

ChoZo simply stared. Shining Armor could feel his glare through his brills. Then, he said "NO."

Shining Armor studied his face for a while, then decided that he was telling the truth. He paused, then asked "Do you know what happened in Ponyville during the last week ?"

ChoZo thought for a moment, then answered "NO."

"Creatures like you came in town. Except their only intent was to kill. The civilians cannot defend themselves. I have one last question for you : are you willing to help us defend them ?"

"WILL I GET TO BUCK PONIES UP ?"

"... some of them."

"WILL I GET BUCKING MEDICS ?"

"... I'm fairly sure Nurse Redheart will help you in times of need."

"... DEAL"
