Chapter Text
Izuku Midoriya, a quirkless boy with a seemingly dormant monkey quirk. This kid had a monkey tail peeping out of his back which opened up to an immense amount of teasing. Specifically from Katsuki Bakugo and his acquaintances.
Throughout his life in school this occurred, over and over again, developing Midoriya's timid personality and thirst for knowledge on basically everything about heroes.
__
Middle school came around as Midoriya walked around the school. The usual occurred, he was bullied, shoved around, but the last straw came when his notebook about heroes was completely destroyed. All the notes were barely legible, and Midoriya was nearly destroyed when he saw Bakugo blow it up.
Midoriya walked through that dank tunnel that he usually took to avoid Bakugo and the other cronies. It was especially gloomy in that tunnel, but it was quiet and isolated, nobody would follow him there. His footsteps echoed throughout the tunnel as he walked over a sewer lid. Muttering to himself and cheering for himself about how he would become a great hero, with his monkey tail flailing around.
He went on home.

A couple of days later, Midoriya was wandering the school grounds and getting shoved around. This time, Bakugo was roughhousing him with his quirk and dealing more than enough damage to Midoriya to knock the wind out of him. This beating he was taking and his attempts to fight back were put down by Bakugo's accomplices.
Midoriya was getting extremely desperate, and out of instinct his eyes flashed, and suddenly a white aura burst out sending the other students flying. Midoriya stood there, breathing heavily, panting, as Bakugo and the others looked on with shock.
In an instant, Midoriya charged. After being beaten to a near pulp by Bakugo and his posse Midoriya's unique genes kicked in. Something that the public might've called Saiyan genes. But...no Saiyan had been publicly seen in a thousand years so, it was completely unknown to all.
Thanks to the beating Midoriya received his genes had used that beating and the fact that Midoriya had struggled so much to amplify and awaken Izuku's hidden power that remained dormant for the last 12 years of his life.
Midoriya dashed forwards and drew upon his hero notes, primarily drawing on a classic move...
"TEXAS SMASH"
Midoriya punched Bakugo in the face with a fairly strong punch, surprising him. The posse moved in and landed multiple jarring kicks to Izuku's back, stomach, and legs. Meanwhile, Midoriya adapted quickly, blocking one after another. Quickly overwhelming the gang before kicking them back and landing blows to their stomach, which Midoriya knew to be a relatively sizeable weak spot.
Bakugo came rushing at him with his hands crackling with explosions as he thrust his right hand towards him, before Midoriya countered, grabbed his arm and flipped him over. Slamming him into the ground. Bakugo leapt back up and came at Midoriya again, as they made contact they exchanged blows.
With Bakugo screaming and hollering obscenities as Midoriya blocked and countered on pure reaction and speed, thanks to his genes, the teachers started to notice and ran over.
With both of them about to punch each other, one of the teachers stepped in a stopped them both before the school would get sued for allowing children to use quirks outside of school.
Bakugo was taken away as he struggled screaming,
"LEMME AT HIM, THAT DAMN NERD. DEKUUUUUUUUUU"
As Midoriya watched as they were both taken back into the school.
Midoriya didn't know where that burst of power came from, but he was excited. In tears as he went home that day. He had unknown abilities. He could become...a hero.
