A/n: okay so you are wondering about the nightmare part...well you have a power to bring in the worst fear of mortals and you are badass and have a thing for hoodies that are either blood red at black... enjoy :D
You were walking down an alleyway in the middle of the night because you were bored and you are lazily finding a victim to scare, you found a teenager so with a snap of your fingers you made an illusion of (insert man's nightmare) and you smirked from below as the teen stumbled on his bottom and had an anxiety attack and fainted.
After your few minutes of evil pranks you stopped in your tracks to see a small boy with dark brown hair and a curl on his head, he was running, scratch that , more like limping towards you and he looked up, his magenta orbs staring into your (e/c) ones "h-help me....please! " you were surprised there was never a single child in your dump of a city considering that the city was the most dangerous places... so why was the kid here?
Before you could say anything you heard a yell, that sounded like "YOU BRAT! GET BACK HERE!" you pushed the kid behind you and gave a deathly glare at the man which you assumed was a pedophile... the man stooped and found the kid behind you and said in a drunk manner ( I wanted to write drunknese but this is a badass fan fiction) " hey b****! that is my victim so if you'll be giving him back now!" you eye twitched you highly detest that word it reminded you of your no good whore of a mother that left you to rot in the city, the boy tightened his hold on your jeans and whimpered.
You scowled and answered with venom dropping in your voice "why should I? as I know this city has nothing but idiotic pedos like you..." the man was about to hit you but was stopped by another one that looked skinny.
"what is it?!" yelled the drunk at the skinny man "I don't think that its a good idea to face her she's the rumored monster that has night powers or something!" you smirked at the thought that the skinny one knows who to fear and the man just laughed and shoved the skinny man off of him and charged at you "kid... go behind that bin you probably won't like what I'm about to do" the kid nodded and his and as the man was about to strangle you you snapped your fingers and out came a demon snake and tore him to pieces before devouring his heart you looked at the corpse then to the skinny man and gave him a death glare messaging him to 'don't mess with me or your I will have your soul' he got the message and ran away.
'pussy' you thought and tour eyes went back to the kid who was crying you walked up to him and softly patted his head ( in case you ask you used to have a sibling but was killed by those gangsters) he looked up at you and stopped crying " hey kid the bad man is gone now....what is your name?" " m-my name is Luciano", "well nice to meet you Luciano I'm (y/n) what are you doing in a place like this....you do know that this is not a playground for children" Luciano looked down and responded "we were left here by our parents and these gangsters came and took us into a dark scary building and I got out but my other half-brothers were caught" and he started tearing up again.
You sighed and wiped his tear away with your thumb and smirked " don't worry Luciano I could help you get back your brothers but on one condition" he looked at you with a face screaming hope "really!? what condition?" you picked him up and held him close to you "I'll help. you in return you are to be my little brother, I kinda miss being the elder sibling so have we a deal?" Luciano nodded and you walked to the darkness.
Meanwhile in the dark building that held the worst gangster in the city also known as the man named Nolan Haveweare he was known to sell the most prohibited drugs and made money by stealing or more likely kidnapping children and women found in the city and selling them to rich men who are looking for 'toys' to play with.
He was looking at his henchmen that held two boys, one had blonde hair and purple eyes and the other had black hair and red eyes.
"boss we lost the other one but at least we caught these two brats" said the henchmen Nolan got up from his chair and smirked darkly at the two, the. blonde boy spat his face that earned him a slap from his ringed hand and before he could slap him again the door burst open revealing you and Luciano.
Nolan smirked at (y/n) and looked at her with a dirty face "long time no see... (y/n)" you growled and proceeded to walk your way to the center of the room giving him a stoic face as a response that you did not care nor give a damn in his warm 'welcome'.
"So what brings you here this time (y/n)? maybe you're finally gonna accept my proposal" he said in a seductive voice your stoic face turned to a venomous glare of death and that the room was almost cold and creepy and a few of the henchmen took a step back.
"what makes you think I would be here to waste my time playing with a sick f*** like you...I came here to get the kid's brothers is be kind enough to give them back" Nolan laughed maniacally and wiped a tear the feel from his eyes and ordered the men to pin you down but you smirked and clapped your hands twice and a black hole came out below surrounding you and out came various monsters from a child's nightmares and started tearing, shredding the men all was nothing left but Nolan and you...
Nolan was trying to hide his fear but you smirked knowing now that he is facing a fate worse than death itself "aww is the big guy all scared and gonna wet his pants?" you teased he. growled at you and grabbed Luciano that was picking the lock that held his brothers in a rusty cage and pointed a knife at his head.
You're smirk turned to a deathly glare, Nolan noticed your overprotective aura and dug the knife into his forehead and small amounts of blood began trickling down, he began crying "Luciano!" yelled the blonde.
"So what's it gonna be (y/n)?" you were at a loss for a plan to kill Nolan without having to have Luciano hurt or killed, you held your hands up in the air and he let go of him and with even noticing that the recruits hit you on the head with a metal pole and began beating you up you could see Luciano with shock in his eyes, you were getting beaten up in front of him, he remembered the beatings he took from his mom and dad and Luciano had a deadly look in his eyes and took the closest thing next to him which was a glass shard and dug it in the man's shoulder the beating stopped and they were taken down by Luciano and not long before the blonde and the black haired boy began smothering the now fallen henchmen with things they got their hands on.
Nolan was in a corner now shivering violently in fear you're eyes went from (e/c) to a blood red void and bloody hands with torn bandages held him to the ground and you looked at the two boys " what are your names little ones?" the blonde responded Lutz and the black haired one responded Kuro you smirked, "I'm (y/n) your new big sister since you enjoy killing those d***wads over other why not give this man a little lesson?" the boys face lit up and started (insert ways of torture and tell me what you had in mind in the comments).
It has been 6 minutes after their little game with Nolan you smirked and walked out of the building with your newly found brothers.
~~>>extended ending<<~~
It was 2013 and you got home from work at an art museum and you saw Luciano all pissed off, " okay what happened Luciano?" Luciano looked at you and back down at the floor "Big sister, (name of slutty girlfriend) broke up with me..." you raise an eyebrow " there is more isn't there?" it was Lutz's turn to speak "yes Big sister turns out ve found out zhat (n/o/s/g) cheated on him vith ozher men behind his back before she broke up vith him" Kuro nodded in agreement and Luciano threw another knife at his ex-girlfriend's picture on the wall.
You put your things on the table and went to the garage and returned with your car keys, "hey Luciano...heads up" you threw your keys at him which he caught and looked at you with a surprised look on his face " Big sis... you don't mean..." you smirked " yep I thought it might cheer you up.... if you hate her so much then why not show her that no one messes with you..." he smiled darkly and ran out not before giving you a thank you and went to the garage to drive Steve (you own a monster truck with a flame throwing pipes in the side and spikes on the front plate).... yep you had the most violent brothers in the world and you were their crazy big sister.
