When a boy with a quirk that can turn him into a monster is kidnapped by the league of villains and used as a experiment escapes. Will he become the hero he wants to be or will he become the monster everybody thinks he is?
I do not own my hero acade...
Y/N was sitting in the living room of his house with his parents watching him play his games. Because he was taking notes on the monsters so he could use them to become the next #1 hero. Or at least that is what he thought was going to happen. Later that day his body was slowly starting to break down his parents took him to the hospital to help him but nothing worked.
All hope was lost until one day his favorite super hero All Might came to see his number 1 fan.
All Might: I AM HERE to see my #1 fan.
Y/N: ALL MIGHT what are *cough* *cough* you doing here?
All Might: To see you of corse. Are you starting to feel a little bit better?
Y/N: A little bit. It still hurts to breath but after I get better I'm going to be just like you All Might.
All might: Oh and what might that be?
Y/N: I'm gonna be the *cough* *cough* *cough* *cough*
M/N: He wants to be the next #1 hero.
All Might: Well in that case get better young Y/N. I can't wait to see you become the hero you want to be. Just remember as long as I am here everything will be fine.
Y/N: Thank you All Might.
All Might: well I have to go this city still needs to be saved!
Y/N: Ok bye All Might PLUS *cough* *cough* ULTRA!!
All Might: PLUS ULTRA!!!!
Little did everybody know everything will not be fine.
*Later that night*
While the hospital was asleep a strange man in a doctors outfit was walking around as if he was looking for someone until he came across the room he was looking for. The man was hired by All For One to kidnap a child that he believed could help create his latest idea the Nomu. The man entered the room labeled Room: 237 the patient's name was (Y/N)(L/N).
???: Ha this is going to be too easy thanks to the boss I can get this kid and get out without any problems.
M/N: Oh hi I was.......wait who are you?
???: Oh sorry I came to take little Y/N to surgery sorry for not knocking.
M/N: Oh ok....wait Y/N isn't supposed to.
Without finishing her sentence the kidnapper shot her and the father before he even woke up. The criminal then went to Y/N and proceeded to knock him out and carry him away from the hospital.
*3 hours later*
Y/N woke up and realized that he was in a place that was unfamiliar to him. He soon heard a voice that would haunt him forever.
All For One: Hello there little one.
Y/N turned his head to see the leader of the league of villains All For One.
Y/N:W-Why am I here? Where is my Mama and Papa?
All For One: Your parents are in a better place.
Y/N was absolutely terrified of what the villain said
All For One: To answer your other question I had you brought here to help you with your illness and for you to help me.
Y/N: H-How could I help you?
All For One: Don't worry about that just relax but fair warning this will hurt quite a bit.
All For One then picked up a syringe full of a mysterious purple liquid and injected it into Y/N.
Y/N:AAAAAHHHHHH!!!!!!
All For One: Now now hush my child it will be alright.
*3 years later*
Y/N has been the experiment of All For One for 3 years but Y/N has a plan. Whenever the scientists come to get him he is always knocked out with a tranquilizer that knocks him out slowly until one day he noticed that he goes outside to get to the lab and his cell so he came up with a idea. Before they would knock him out again to go back to his cell he would start to use his quirk so he wouldn't be knocked out. He then pretends to be knocked out until he was outside to go the other building.
???: Y/N time head to the lab.
Time for Y/N's plan to begin
*2 hours later*
Y/N was finally free from that hell that he was in for 3 years his plan worked flawlessly. Now it was time to survive in the city. But he knew he needed a mask to cover his face from everyone so he looked around the city keeping to the alleyways to stay out of sight until he found a mask upon a wall.

He called this mask akuma because he knew that he would be a devil to the people who put him in that hell and so the Oni was born.
Y/N has been a vigilante for 2 years now he had finally found out where the man who took him that night
