All this led to Murphy feeling an emotion he never felt before in his past life : Anger.
The cries of the principal's child was hurting his ears but he could clearly hear what the teachers were telling him. They told him that it was against the rules to not tell when your quirk awakened and he should have went to the hospital to register as a quirk holder.
They also told him that with such a personality, he was not fit to become an hero and he will become a villain in the future since he like to hurt his classmate. Murphy couldn't even talk back to defend himself, Izuku and Katsuki tried to help him but there words were ignored by the grown up who told them Murphy was probably lying to them. But they didn't believe it since they were together every day, week end included, if Murphy developed his quirk and trained to have perfect control of his it, they would have knew. They tried to argue back but the teacher told them to stand in the Hallway for insolence
The other children started to talk but Murphy could still hear what they were saying.
Kid 1 : Scary, he's a future villain
Kid 2 : He will not even be a good villain, hid quirk only allows him to protect himself
Kid 3 : Do you think that's the reason his parents left him?
Kid 4 : What do you mean?
Kid 3 : He doesn't have the same surname as Midoriyia so he must be adopted
Kid 4 : Maybe they left him because he is trash
Kid 2 : Trash parents can only gave birth to a trash son
Kid 5 : Maybe he wasn't even wanted that why they ditched him
Kid 4 : Mom told me that only failure and whores ditched their son when they are born
Kid 6 : Don't let the whore's son touch you, you will become a failure
All kids then proceeded to call Murphy a failure. The teachers didn't stop them. Murphy who was already angry with all this injustice didnt mind that they talked bad about him, but when he heard about his parents his anger started to grow even more. But when he heard them talk about the only woman who loved him and whose love followed him in his reincarnation : his mother. He lost it.
Everybody in school then felt a pressure, it was even possible to feel it in the neighborhood, the pressure emanated from Murphy and the closer you were to him the stronger it was. Murphy didn't know what was happening around him, his head hurts like it was about to crack open, he yelled from the pain but he was unable to become unconscious. He felt something burning and freezing his head at the same time.
An iced winged band started to condense around his around his head. But it was not only ice, there were also water and steam. The winged band was alternating between ice, water and steam but there were a majority of ice and water. The steam was only on the upper part, the ice was around the water and the water was circling freely in the ice tube. It looked a lot like Jin Mori's winged band but more majestic.
When the winged band finally stabilized, the pain disappeared and he opened his eyes, the pressure vanished as if it never existed before. His eyes were no longer light blue but dark blue like the depth of the sea by looking into them you felt like falling in never ending abyss.
He didn't feel anger the pain washed it all away but he knew he had to do something to the people who mistreaded him or they will think he was some pushover. He knew he had to punish them but if it he didn't know how.
What he didn't knew that at that moment his will manifested and took his wish to punish them as an order. It then proceded to decide the punishment based on Murphy's thought. Murphy wished that such people should never be able to procreate.
His will used the water in their body to destroy their Sertoli cells for the boys and their primordial follicles for the girls. They didn't felt pain but they knew they lost something really precious. Murphy's winged band then disappeared and he lost consciousness and lied on the classroom floor.
Teacher 1 : We should probably call an ambulance for the brat
Teacher 2 : And the heroes too, he stole something from me, I feel it.
Teacher 1 : You feel the same too?
Teacher 2 : We better call heroes to put him under strict oversight
Teacher 1 : He is some great villain material
They then proceded to call an ambulance for Murphy. While the other kids were crying.
When he woke up, Murphy was in a familiar place, a movie theater. A man he never though he will see this soon was standing in front of him.
Ame : You realised you almost died because of your own power right, and now you are in a dangerous position in your world.
