Izuku Yagi was bullied by his so called sister and class 1-A for wanting to be a hero despite not having a quirk. For the past 10 years they made his life a living hell no matter where he was. In their mind they believed that this was to "protect" him from the dangers of wanting to be a hero without a quirk.
The bullying continued at school as other kids got involved, belittling Izuku for his dream of being a hero and beating him up on a regular. It didn't help that the teachers were completely bias and believed that he was inferior to the rest of the quirked students thus leaving him to fend for himself.
This was slowly eating away at his mental state as he became fidgety around people and was constantly looking for ways to to avoid the hellish life he was enduring. Until one, after another beating from his tormentors causing him to be knocked out for a bit.
Deep within subconscious a parasitic life known as Baby came to him. Offering a chance of Revenge for all the hell he endured by society all he have to do is let Baby take control of his body. Tired of the pain and suffering Izuku let himself be consumed by Baby as he gave up complete control. Now the Parasitic Life Form who had survived his bout against Son Goku was back to take over this new universe.
Baby: "These fools won't know what hit them. I'll just lay low until the time is right to strike but first it's time for this body to stop being a punching bag once for all!"
Outside World
Katsuki: "Damn freak! Hopefully with this beating you'll know your place in the world trash!
Izumi: "I don't know why my parents even bother keeping him around. He's such an embarrassment to the family."
Shoka: "Worry not Izumi. Nobody will ever care about this piece of trash, once we become the next generation of heroes."
Shoto: "Let's go we've wasted too much time dealing with the filth. It's time to head back home."
Katsuki: "Alright, but first I'm gonna get one more kick in for good measure."
As Katsuki walks over to the "unconscious" Deku. Towering over his body with a sadistic smirk on his face.
Katsuki: "You honestly should just die already! Nobody will ever care about you!"
As Katsuki cocked his foot back going in for a lethal kick to Izuku's temple, only for the kick to be caught the last second, surprising the ash blonde boy.
Katsuki: "W-What the hell?!"
Shoto: "What's the matter Katsuki?"
Suddenly "Izuku" had awaken, calmly getting up as he still had Katsuki's foot in his grasp. Dusting himself off and wiping the blood for his face. As his hair suddenly turned white and he had red line's appear above his eyes, as he looked to his tormentors with cocky smirk.
Izuku: "You know. It's funny. You say you want to be heroes, but all I see are a bunch of villains. Oh and by the way.
