Greater Darkness (RWBY x abused and neglected reader)

Chapter one

Y/n's pos

They did it again... "Why?" is all I could ask, why did my "family" beat me up everyday? And why do they leave me in the basement? Their answers were clearer then a perfect diamond. "Because you're a mistake and should have never been born!" is how they answerd the first question and the second was, "We keep you down here because you're a monster who needs to be cadged!" I may be a dragon fanus but I say "cadged" is a bit to far, but sure enough my "family" put me in one and my sister plays as the hero with her weapon that had three from, a sword, a spear, and a gun. Right now I was in my "home" as in my cage just thinking, because I had no scroll to look at and no books to read, my cage is like a bird cage but for a human sized individual, like myself. I hear the door to the basement open then closed as I thought 'Wow 9:30 already? I must be time traveling, I could have sworn it was time for me not getting hurt by my sis" I chuckle at what I thought and that was a mistake because I saw her sword pointed straight at me ready to kill at any moment, my sis spoke at a rather angry and hateful tone "Why are you laughing? Not enough pain for you? Ok I need to train for my upcoming tournament anyways, so let me teach you a lesson"

She then opened the cage and dragged me out then threw me agenst the wall, I fell to the floor, she walked over to me and pulled on one of my wings and did what I thought none of them would do, I screamed as she started to cut my wing with her sword, she stopped for a moment and stomped on my head "SHUT UP YOU MONSTER!!!" and she continued to cut my wing and I continued to scream in pain "IF YOU DON'T STOP SCREAMING I WILL CUT OFF THE OTHER ONE TOO!!!" she threatened, before she fully cutted off my wing she stood up and grabbed the end of it and pulled hard, I screamed even louder and she stomped on my back and pulled harder, pulling, and pulling, until *Snap* my wing was ripped off.

I also felt something else snap inside my head, I hear her chuckle as she grabbed my other wing, as soon as she did so a huge black wind swirled around me and pushed her to the wall as my body underwent a transformation.

I grew horns about 2in long and my eyes became red as dark if not darker then blood, I also grew a dragon tail while all of this happened my skin became darker/paler, once the transformation was complete a sword also appeared in my hand as I stood there looking straight at my sister with nothing but hatred and anger

(With only one wing)

She was sacred be on diselief that her brother took hold a knew from, one that looked far different from what I normally looked like. I took one step and I saw her attempted to run to the stairs that lead upstairs, but I teleported and front of the door the lead outside of the basement, looking down at my sister, she had almost nothing but fear and horror in her eyes, I opened my mouth to speak but I spoked in a much deeper and more demonic voise it surprised me at first but I intently grew a likeing to it "What do you think? Are you happy that you brought fourth a dragon demon? Is the hero going to slay this new beast or will she be the beast's first victim?" I questioned and before she could reaponed I grabbed her face with my free hand and used her to break the door and I also threw her through the wall of the house, as I started to walk towards her as she crawled back scared that she might die here. I slowly tower over her as I raised my sword into the air and was about to swing at her, but a Nevermore grabbed me and flew away before I could kill her. I struggled againsted the Nevermore as the same black wind that pushed my sister away came back but instead it made my sword's blade become black, I slashed at the Nevermore and a black slash was launched from my sword, and cutted the Nevermore in half, I was falling down with the two halfs of the Nevermore as I thought "This is how I die? I finaly brake free from my prison a now I will fall to my death? ... Heh. Heh heh if only I had my other wing I would fly outa here faster then you can say shit" as I thought this I could see the ground, it was a forest but with in it I saw two people walking, one had snow white hair while the other had blond hair "HEY!!!" I shouted but they didn't hear me so out of quick thinking I threw my sword downward, I was lucky I didn't hit either of them, my sword hit the ground they seemed shocked but soon they looked up they saw how close I was and before hitting the ground, the blond one used a ridding crop and I suddenly fell much slower and soon landed my feat. I thanked the lady for her help, but I soon felt light headed and fell to the ground, everything went into slow motion as I fell my transformation peeled away in scales like feather would in the wind, as I became my normal self and the world around became black...
