(Ok since no ones saying shit about characters I'm just going to do what I want and swap Midoria, Bakugo, and Todoroki for there genderbent versions)
Y/n pov
Walking to school used to be an everyday thing for me, wake up, get ready then go. But I don't think a school is supposed to have a large crowd of people in front of it asking for All might, the legendary hero.
My father hates him, saying that someone that reckless and happy go lucky shouldn't be allowed to have a stand let alone a quirk. My father was kind of a big talking son of bitch but when it came down to power's he never seemed to be wrong, except for when it came to Blue on Black who quickly began to outmatch star platinum. After making through the crowd of people with Momo hot on my tail we began to head towards the large building with a giant U and A on it. I looked over to my right and saw some kid with Green hair trip and get stopped mid air after a girl with brown hair tapped the kids arm. It didn't even take a second for me to realize that her quirk was zero gravity and anything and everything she touches will begin to float. Momo noticed me staring at them and tried getting my attention.
Momo:"Hey Y/n you good or you just going to stare at those two longer."
Y/n:"Just figuring out quirks is all never know who could become an enemy." I said as I walked off Momo taking a second to think before chasing after me. I may not always agree with my father but if there's one thing that I picked up from him is to always be alert on who your friends are and to be cautious when going against the unknown, that and his ability to tell what powers others have. When we got to our class most people were already there. I saw a seat open in the back and took it keeping not of the seat diagonal and in front of me. To my right was a girl with both red and white hair and a large burn mark over her left eye.

She sat there silently looking through a book titled "To kill a Mockingbird." I heard it wasn't a bad book but I never really showed interest in it. Momo had taken the seat diagonal to me and was talking to an Invisible girl and pink alien girl, leaving just the seat in front of me open, I decide to rest for a little bit and clear my head those reporter's gave me a massive headache. I kick my feet up on my desk and tip my hat over my face blocking out the lights. About a minute or so passed and I felt something cold touch the back of my neck, instinctively I shoot up and summon Blue on black before realizing that it was the girl next to me she had snuck up behind me and touched me with her now ice covered hand.
Red and white:"You might want to stay awake next time so you don't cause a scene." I turn around and notice everyone looking at me including the teacher I fix my hat and send Blue on Black back to my soul. I silently thank the girl and sat back down. I also noticed that the green haird kid from before was sitting right in front of me murmuring about my stand. I just ignore them as the teach gives out Gym uniforms. We go and change before doing a bunch of tests all of which I excelled at. When I was watching people through the soft balls I noticed that the green kid who I noe know is a girl named Izuku Midoriya

Was rather nervous and It didn't help that, as it turns out, she was the one who decked the robot in the face but at the expense of her now healed arm. I walked over to her and patted her on the shoulder lightly, getting a cute eep out of her before she turned around to face me.
Y/n:"Midoriya right? Let me guess your concerned about breaking your arm again, to save you sometime try to put that powet into just the tip of your finger that way you can still move your arm around." She didn't even really get the chance to speak before she was called up to throw, she gave me a quick nod and picked up one of the balls and packs her power into the tip of her finger. She then manages to throw the ball to 705.4 meters farther then everyone except for the girl that got Infinite cause fuck beating her score. She then jumps around real quick before running back and thanking me. I smirk at her saying it's no problem earning a light blush from her. I'm then called up to the plate. When I get up there Blue on Black gives me one of the balls and I ready for him to throw it.
Aizawa:"Hold up." I stop and look at him his hair spiked up like an anime characters his scarf also up and flaring. I then recognized him along with Midoriya, my father would always talk about a hero who should have been one of the higher ranked ones,  Eraser head. He was one of the few heroes my father respected and word has it that the two were actually friends at one point. "Your Jotoro's kid right? That would explain why your quirk wasn't erased."
Y/n:"Yep and I'm surprised you recognized me without my father near by."
Aizawa:"He still got that dumb look on his face when he gets mad."
Y/n:"He never lost it so now if you'll excuse me." I said as his hairnand scarf returned to normal. I then threw the ball to just under Midoriya's score, 705.3. Blue on Black dissapeared as we all headed inside and changed back to our original clothes. Friends talk amonst friends while me and Todoroki, the white and red haired girl, just sit in silence. Me on my phone listening to music without headphones quietly and her reading some more. I was kind of enjoying myself before a hand slammed down on my desk creating a small explosion as smoke rose from the girls hand. I paused my music and looked up to see her.

Katsuki Bakugo. A girl with an explosive quirk and attitude. She was kind of a bitch but was secretly just like everyone else. A kid.
Bakugo:" You think your so cool just cause your all buddy buddy with the teacher. Know your place and stay out of my way otherwise your going to a pile of ash on the floor.
Y/n:"Yare Yare daze." I muttered before standing up having to look down at her in an intimidating fashion. "Listen Bakugo I never needed the teacher to beat you, if I have a problem with someone I deal with it myself." I say putting my phone in my pocket.
Bakugo:"Why you son of a bitch! I'm going to kill you here and now!" She said as she reached for my face with her hand showing small explosions. Blue on Black immediately grabbed her hand stopping it inches from my face, the explosion still went off but the best part is seeing her face when she realized I wasn't effected at all. I was about to say something but the bell rang. I let her arm go and began to walk out with blue on black gone and Momo not far in front of me.
Bakugo:"Hey get back here I'm not done kicking your ass!"She said. I quickly turned around and glared at her.

I took everyone by surprise by that, and I'm glad I did. Let them know not to fuck with me.
