I got this idea while watching One Punch Man and thought that would be a funny Reader Insert!

Expect a lot of cracks and you the Reader just finish off all the villains before they can do anything :D

Also, multiply endings cause anybody should get the chance to smooch who they want :D

Tell me who you want to end up and I will count the votes.

The character who gets the most votes gets the first ending and then so on.

And yes we can date the girls and also poly is possible and harem if you like! ;D

Chapter 1: The Origin Story or Something

There was absolutely nothing special about your birth.

You weren't a prophecy savoir of the world.

You were just a tiny baby, who screamed.

Loud.

And annoying.

Still other than most protagonists your parents weren't shitty assholes and actually loved you.

So good for you.

The first four years of your life were dull and boring, so we skipped that.

You just did what kids did at this age.

Playing, eating, shitting your pants, you get it.

Only when you came to kindergarten and some of your friends started to sprout wings, making things float and one memorial occasion wetting your teacher from head to toe since they turned into literal water, did you know that something wrong was going on with this world.

A normal child would have surely freaked out but you weren't exactly normal.

You felt often like an adult in a child's body.

So calmy this evening during dinner you asked your parents what was going on.

Did you live with mutatens or what?

Both your parents started to cry and hug you.

They confessed how they were Quirkless and the chance was high that you were it too.

Yeah, thanks it didn't really explain it.

A long explanation about Quirks and what being Quirkless meant followed.

You felt how your parents suffered under it being two of the 20%, who didn't have a Quirk.

You did feel sorry for them.

However, if you were also quirkless you didn't care.

A Quirk had never been a part of your life, why should you wish for one?

Nah, too troublesome.

You thanked your mother for the meal and wandered over to the TV.

Your favourite cartoon was about to start.

Your parents stared in disbelief at you.

Then your mother turned to your father and told him you got this aloofness from his side of the family.

Your father pouted.

Even if you didn't care for a Quirk, the world didn't make you forget it, how you were a freak without one.

Your fourth birthday came and went and after months of nothing and a doctor's appointment, it was clear you were Quirkless.

Again your parents embraced you crying, begging for your forgiveness.

Awkwardly you patted their heads.

They made such a drama over nothing.

You were fine.

You were still fine as your friends started to avoid you and some even bullied you.

You just punched them in the nose.

Quirk or not Quirk if someone is fast enough they can punch anyone.

Still, it got on your nerves.

Years passed and it got difficult to punch back against the bullies.

They had their Quirks to back them up and you...just your own muscle strength.

Well, before Quirks people trained their muscles to be stronger.

Why shouldn't you do this too?

So at the age of ten, you start with your workout routine.

It consists of 100 situps, pushups, and squats followed by a 10-km run.

For three years you go through this hell, no break, never.

Only training.

Then one day when you were thirteen you woke up and your [haircolour] hair had turned long and white.

It was also the same day you managed to land a punch at one of your bullies and..well they died.

Ups.

Yeah, it was chaos after.

Police, your parents, the parents of the child you murder.

So troublesome.

After a lot of tests, you still turned out to be quirkless, no one could explain where this power came from.

Since you did kill someone, even if you didn't want to, you came into a special facility run by the government.

Away from anyone, where scientists tried to crack your mysterious power.

God, it was so boring.

Day and day the same tests, the same tasteless food and the same session with your shrink.

Your aloofness was worrying them too.

You did feel bad that you killed the kid, but the asshole had bullied you your whole life, he just got what he sown.

So no regrets.

Okay, that your poor parents lost their only daughter to the government and all the kids you traumatized was not good, but what could you do?

You couldn't change what had happened.

So you lived your life as a labour rat, having not much hope of getting out of there.

Till the day a literally rat-dog-bear thing visits you.

It was actually the end of your normal day as a labour rat when anything changed.

Finally, you could relax in your room and read some manga.

Watching anime you could only do on two days a week.

But reading you could anytime.

Surprisingly someone knocked on your door.

"Who?", you asked bored.

"You have a visitor.", told you, your guard.

Okay, you got curious.

Besides your parents, who finally got permission to visit you once a week, you never had visitors.

You sat up on your bed and a rat-dog-bear thing in a fancy suit entered.

He gave you a friendly smile.

You blinked.

"Are you also here to get experimented on?", you asked aloof.

He laughed.

"Oh, these times are long over...I'm actually here for you."

"For me?"

"Yes."

"Why?"

"I don't know how much news you heard but did you hear about the attack on the USJ?"

You frowned for a second before you remembered.

"The hero school U.A. got attacked by this lame ass named League of Villains, like if you are evil then choose a treating name.", you told the speaking animal.

This made the animal laugh.

"Couldn't agree more, I'm Nezu the principal of the U.A. And I came here with an offer for you."

"What offer?"

"What would you say about visiting the U.A. as a normal student and using your mysterious power for the good."

You just stared at Nezu.

After a long discussion with Principal Nezu, you agreed to go to the U.A.

You got your freedom back and could return to your parents if you had to play his guard dog then by all means.

Better than being a labour rat.

The principal hoped to have someone with your power on their side, a power who was even stronger than All Might himself, would give them a chance over the villains.

You were just happy to be home again.

Your parents had been so sweet to turn your room into a room for a 15-year-old, even if you were so long in the facility.

Being back home, made you for the first time really happy in your life.

You only realized how good you had it when you lost it.

Then when your mother made your favourite dish, a single tear fell from your eyes, which was bawling your eyes out for you.

In the embrace of your parents, you felt loved and ready for anything.

Because you just needed One Punch to clear all the problems.
