"Ah just think a relationship between Flash and Twi would not last that long!" Applejack said as she and her friends left the main building of Canterlot High; Applejack and Rainbow Dash led the group, followed by Rarity, Fluttershy, Pinkie Pie and Sunset Shimmer, walking past three young girls who were kicking a ball around, giggling and having fun.

"Whatever are you talking about, darling?" Rarity asked while typing a quick text message on her phone. "I think those two are lovely together."

"But isn't she, like, royalty or something? She's also some horse-thing, too. Wouldn't that make it weird?" Rainbow Dash pointed out.

"Oh, you can look past small details like that when you're in love!"

"What 'bout her doggie? Lil' fella seemed really into you. Can you look past that small detail?" Applejack poked her friend, a cocky smirk plastered on her face.

"Why do you always have to exaggerate everything, Applejack?" Rarity puffed out her cheeks and blushed lightly, remembering that one night they were having a sleepover at Pinkie's. She woke up in the middle of the night, only to find out that the purple dog was shamelessly humping her leg, and the fact that she wasn't wearing her socks only made it much worse. Her high-pitched scream immediately woke all of her friends up - Pinkie's sister even kicked the door down while armed with a baseball bat.

"It's too bad you rejected him, Rarity!" Pinkie grabbed Rarity's shoulders. "I had already planed the wedding party and everything. Wanna see the wedding gown I made for the bride?" the party girl then dangled a white knee high with a frilly hem stitched to the cuff in front of Rarity's face.

"Can we just not speak of that... Unfortunate event ever again?" Rarity said between gritted teeth. She slapped the sock away from her as the other girls laughed.

"And what about you, Sunset Shimmer?" Rainbow Dash asked without looking back at her friend. "What's your opinion about the Flash Sentry/Twilight Sparkle situation?"

"Rainbow Dash!" the fashionista called. "Don't you know how rude what you just said was?"

"What are you talking abo--" it finally hit her. Rainbow Dash rubbed the back of her head in embarrassment. "Yeaaaaah, my bad!"

Sunset Shimmer sighed. "I told you a million times already: I. Don't. Mind! Flash can date whoever he wants, we're done."

"Uh, forgive me if I'm being too intrusive, and you don't have to answer if you don't have to, but..." Fluttershy looked around, as if making sure that no one else but them would hear. "Why did the two of you broke up? You never told us. You never told anybody."

Sunset Shimmer froze in place; that question definitely caught her by surprise. All the other girls stopped and turned to look at her.

"L-Like I said, you don't have to answer if you don't want to."

"It's not that I don't want to, I just... I don't..."

The blonde/redhead girl never hid anything from her friends, but there was one secret that she never shared with anybody except Flash Sentry, and only because they shared the same predicament: they suffered from memory loss, and forgot everything about their alleged relationship. The only reason they knew they were a couple was because their classmates kept pestering them about it, asking why they were no longer hanging out, sitting together or even talking to each other. They decided to check with each other what this was all about, but they were both clueless about everything, thus ending the relationship they never knew they had.

But before Sunset Shimmer could come clean, she saw the ball the girls were playing with bounce past them and come to a halt in the middle of the street. The five girls were looking at her, so she was the only one who saw it.

"Scootaloo, why'd you kick it so hard?" Sweetie Belle complained.

"You kicked it, so you go get it back!" Apple Bloom ordered as she crossed her arms.

"Fine, fine, I'm going." Scootaloo said as she ran toward the ball, completely ignoring that old advice about looking both ways before crossing the street. She didn't see the white car coming toward her, and the driver, a businesswoman who was too busy yelling at her lawyer through her cellphone, did not see the girl either. But Sunset Shimmer did! Pinkie Pie and Applejack were blocking her path, but she immediately pushed them aside and sprinted toward the pre-teen girl. Sunset would have yelled at her to get out of the way, but the car was too fast and Scootaloo wouldn't react fast enough, so the only thing she could do was push her out of the street.

Scootaloo and her ball safely landed on the grass, but Sunset Shimmer wasn't as lucky; her body dented the hood of the white car and her face smashed the windshield. Startled, the driver stomped on the brake, sending Sunset's limp body flying, which then landed in the bushes in front of the horseshoe sign on the front lawn of Canterlot High. Rarity screamed in terror and Fluttershy fainted in Pinkie's arm, who just stared in shock at the scene. Applejack ran toward the place where Sunset Shimmer fell while Rainbow Dash crossed the street to check on Scootaloo.

"You ok, squirt?" she asked while looking for any injuries on her body.

"Y-Yes, I-I'm fine."

Applejack checked the bushes and the immediate area around the horseshoe sign, but scratched her head in confusion.

"What in tarnation...?"

The still shaky Rarity and Pinkie, who was now carrying the unconscious Fluttershy on her back, approached her.

"I-Is she ok?" Rarity asked.

"That's the problem: Ah don't know! Ah'm darn sure she fell here, but now she's gone!"

Rarity and Pinkie Pie looked around, and it was just as the farmer girl said: Sunset Shimmer had vanished.

Sunset Shimmer's eyes fluttered open. Her vision was still a little blurry, but she could feel that she was laying on a cold wooden floor. As she slowly rose to her feet, she could make out her surroundings little by little: she was in the living room of a small and very simple apartment with two closed doors on the left side, two glass windows that allowed them to look at the street several storeys down below, and one empty open small room and a hallway with a turn leading to the front door behind her. It was already dark outside, but the ceiling lights of the room were on. The room would be completely empty if it weren't for the five other people and the first thing that truly caught her attention: a black sphere with a diameter of roughly 4 ft standing next to the wall on the other side of the room.

Sunset Shimmer looked around at the five people in the room: one boy with short blue hair, a girl with blonde hair tied back in a ponytail, another girl with reddish-rose hair wearing thick glasses, the three of them appearing to be around her age, a man with short golden hair wearing thin glasses, a very expensive-looking white suit and black tie, and a girl not much younger than her - though still pretty young - with long black hair that covered most of her face wearing very dirty and old clothes that were barely wearable thanks to some poorly made stitches that were keeping the pieces together. The clothes of the man and the girl were eye-catching, but the outfit the three other people were wearing stood out: they were all wearing a black skin-tight bodysuit that only left their heads exposed. The black suits also had metallic rings or caps with their centers filled with a blue gel, which were embedded in key areas of the body: the side of the arms, wrists, chin, collarbones, nape, behind the ears, shoulder blades, lower back, abdomen, waist, the side of the knees and the shaft of the suit's boots.

"Uh, can someone please explain what's going on here?" she asked the group.

"If we knew what's going on, do you think we would just be standing here, doing nothing?" the man said with a very harsh tone.

The blue-haired boy and the blonde girl started to chuckle. Sunset and the man looked at them, who were whispering among themselves.

"Can I say it this time? Please?" the boy asked.

"You won't leave me alone until I say 'yes', will you?" there was a hint of annoyance in the blonde's tone, but her smile suggested otherwise. "Fine, knock yourself out."

The boy cheered with a quick fist pump, then turned to address the people inside the room:

"Attention all bitches!" he then spread his arms. "Welcome to hell."

Sunset Shimmer crossed her arms and raised an eyebrow while the man stared at him with an unamused expression. Sunset gasped in surprise when she felt something touch her waist, then looked back to see that the younger girl was hiding behind her.

The smile disappeared from the blue-haired boy's face. "Fuck it!" he then crossed his arms and pressed his back to a wall. "How come it only works when you do it?"

All of a sudden, a very upbeat tune filled the entire apartment. It didn't took look for them to figure out it was coming from within the black sphere.

"And there we go." the ponytail girl said with a smile.

"Oh, great!" the man said as he removed his glasses and rubbed the bidge of his nose. "First, cosplayers. Now, karaoke. If I knew I was going to end up locked in a room with a bunch of weebs I wouldn't have gotten out of bed today."

The redheaded girl crossed her arms and rolled her eyes behind her glasses, but decided to not say anything, instead opting to keep looking at the black sphere; the others soon joined them as soon as words started to appear on it. For some unknown reason, the letters "S" and and "E" were backwards, but the message was still entirely legible:

"Wait, what?" Sunset asked. "What is this, some kind of joke?"

The blonde motioned for Sunset Shimmer to quiet down without looking away from the black ball. Slowly, the text got replaced by a different text, the letters "E" and "S" still backwards, but this time it was accompanied by the picture of a round creature covered in milky pink fur, big blue eyes and an innocent smile.

"Alright, you guys see this?" the boy asked, pointing at the picture of the Furball Alien. "In a few moments we will be taken outside. Our job is to kill it before time is up, okay? Okay!"

"But mister!" the blonde called, speaking in a tone that made it obvious that she was feigning ignorance. "How are we supposed to do that? We'll have to wrestle them with our bare hands?"

"Great question,my dear! And the answer is 'no'! Well, unless that's what you want to do."

Racks popped out from both sides and the backside of the black ball like drawers, startling Sunset Shimmer, the man and the girl. The left and right rack had what looked like futuristic weapons stored in them. Some of the smaller ones were similar to revolvers, but bulkier, while others looked like pistols, but with three barrels instead of one. The larger guns looked like sniper rifles but, like the revolver-looking ones, much bulkier. All of them were just as dark as the ball itself.

The duo walked toward the rack on the back, which had white plastic briefcases. The girl picked one of them up.

"Which one of you is Sunset Shimmer?" confused, Sunset Shimmer raised her hand. "Think fast!" she threw the briefcase to her, who managed to grab it in time. The boy passed a briefcase to the man, and the girl threw the last at the girl behind Sunset Shimmer, who just stared at it without budging.

"Are you serious?" the man asked. The briefcase with his name was now lying on the ground, open and empty, and the man was holding a black suit similar to the ones the other three were wearing. "Tell me you're not serious!"

"Wear it or don't wear it, I don't give a fuck." the boy said with a shrug. "But if you don't, you're gonna die."

"I'm not some cosplay freak like you!" he said as he threw the suit on the ground. "If the doors weren't locked, I would've left this shithole long ago. I have a very important meeting tomorrow, and I should be getting ready, not wasting my damn time!"

Sunset Shimmer finally opened the suitcase and, as expected, there was a black suit in there. She looked at the blonde girl, who pointed at the corridor.

"If you want to change in private, that's your only option."

Sunset nodded and walked down the corridor. There was another turn at the end, perfect to hide from Peeping Toms. She took a deep breath, then removed her leather jacket and her shirt. She was about to unhook her black bra when she realized she wasn't alone anymore; the black-haired girl was also there, holding her own briefcase.

Both Sunset and the little girl were now wearing their suits, which fit them so perfectly that it was like they were custom-made specially for them. The older man still refused to wear the suit. While the others wore the suit and nothing else, Sunset Shimmer decided to keep her jacket on.

"This here is what we call the Gib Gun!" the blue-haired boy said while holding the revolver-looking weapon. "We call it that because, just like in videogames, it 'gibs' whatever you shoot with it!" Sunset Shimmer played enough games with Rainbow Dash to know that "gibbing" someone means reducing them to a pile of body parts. The boy then threw it to her, who accepted without complaining. Upon closer inspection, she noticed that the weapon had two triggers instead of only one. "The first trigger is for locking on the target, and the second is for shooting. Remember that, it comes in handy in many ways."

"This one is the Web Gun!" the blonde said while presenting the pistol-looking weapon. "Like the name suggests, it shoots a web that binds the target. This one comes with three triggers, though. Like the Gib Gun, the first trigger is for locking on target and the second is for shooting, but the third is for-- You know what? Why ruin the surprise? See for yourselves!" She threw the gun to the golden-haired man, but he just threw it back at her.

"I don't want your toys, thanks."

She shrugged and placed the gun back in the weapon rack.

"You're not taking it?" Sunset asked.

"Nope!" the boy said. "We like fast-paced action! This..." they both picked up the rifle-looking weapons. "...is all we need!"

"Those are the Gib Rifles!" the girl explained. "It's just like the Gib Guns, but the range is much longer." she pointed the rifle and the wall while loking through the scope. "It's pretty badass."

Sunset noticed what looked like a screen on the back of the gun. She looked around the room through it, noticing that she could see the skeleton of the people she pointed the gun at. But when she pointed the gun at the blonde, she kicked the weapon out of her hands, then kicked Sunset Shimmer in the face, sending her flying to the other side of them room. The young girl yelped.

"Point that shit at me again and I'll shove it up your cunt and shoot." she said, her friendly demeanor completely gone and replaced by an icy, emotionless stare.

Sunset got up, surprised by the fact that a kick from that thin girl not only sent her flying several feet away, but didn't hurt at all.

"Surprised?" the boy asked with a smile. "That's the power of the suit. Superhuman strength, and the resistance of a goddamn cockroach!"

The profile of their target on the screen of the black ball disappeared and was replaced by a countdown.

"One hour, that's the time limit!" he then started to disappear, from the top of his head and working the way down at a steady pace.

Sunset Shimmer's eyes widened. "Wh-What's going on?"

"How do you think you got inside this room? Through the front door? By the way, you should pick that up." he pointed at the Gib Gun lying next to her on the floor. "If you go unarmed, you'll definitely regret it." he turned to wink at the blonde girl. "I'll wait for ya, babe!"

Once the blue-haired boy was completely gone, Sunset's little "admirer" was next. The stubborn man was the one after her, followed by the blonde and the quiet girl with reddish-rose hair. Finally, it was Sunset Shimmer's turn to be taken.

"I'm leaving, and a bunch of brats is no going to stop me!"

"I'm not trying to stop you, I'm just saying. If you try to leave, you die."

"Is this supposed to be a threat?"

"No, it's a friendly warning. But if you won't listen to me, then fuck you, old man!"

"You're lucky you're just a brat, otherwise I would have knocked you out cold the moment you gave me back talk."

Sunset Shimmer arrived just in time to witness the two men of the team arguing. It didn't took long for the older man to turn around and walk away. The boy then picked a device that looked like a small cellphone, but with some gadgets attached to it, as well as a metallic bracelet used to attach the device itself to a person's wrist. He then proceeded to follow the man in the white suit while looking down at it. The others, having nowhere else to go, followed them.

"Why are you following me?" he inquired.

"I'm using you as an example." the boy answered.

"Whatever!"

After a couple of minutes of walking, the boy motioned for the others to stop.

"Tired of following me already?"

"Nope! It's just that this is the limit." he turned around and showed the device to the others. "This here is the Controller! It comes with a map that allows us to track our target, each other, and know the limit of where you can go."

"And turn off that damn phone!" the man yelled. "Your ringtone is fucking annoying!"

He smirked. "That's not a ringtone. Ladies and... Well, ladies, pay attention to that man. He is a deserter. A quitter! And you know what the Black Ball does to quitters?"

The redheaded girl clicked her tongue, crossed her arms and turned her head with her eyes closed. The man's head swelled for a second then popped like a water balloon, bits and pieces of his skull and brain flying in all directions, leaving only his lower jaw still attached to the rest of his body. Sunset Shimmer covered her mouth with both hands in shock to prevent herself from screaming, and the girl once again hid behind her.

"They receive the death penalty!"

Author's Notes:

It begins!
You have no idea how much effort I put into planning this. The "script" is over 40 pages long. Just for the sake of comparison, the "script" of Twisted Metal: Equestria was 15 pages long!
I just hope it turns out to be just as good as I wish it to be, I don't want to read it again in a few years and think "What the hell was I thinking? This sucks!"
Anyway, this won't require lots of source material knowledge to follow, though I heavily suggest that you read Gantz because I think it's really good! (though I still think the anime wasn't that great and the movies were "meh")

And to use as reference, here's the Gib Gun (official name is X-Gun):

The Web Gun (official name is Y-Gun):

And the Gib Rifle (official name is X-Rifle):

(With names so boring like that, it's no surprise that I decided to add some spice to them!)

The Suit:

The Controller:

And the Black Ball itself:
