Izuku was born Quirkless to the Number 1 and 8 Heroes. His father was secretly born Quirkless and was disgusted by the idea of his son being the same.
He and his wife neglect the child and don't realise that he vanished when he was 7, only realising...
They slowly lower and inject me, I thrash around in pain, unable to stop, I want to stop thrashing but I can't. I don't want this! But I obey the Doctor! You didn't used to! What? Don't trust the Doctor!
The voice fades as the pain fades and I'm released, I'm... Confused...
What was that voice?
It sounded like... Me?
I'll ignore it's existence for now.
Months pass as I practice my new Quirk, doing as ordered. It's a Perfect Pitch Control Quirk, I can reach any frequency and hit it perfectly. Great for ultrasound frequencies.
I'm put into the Ring.
The Ring is a battleground you have to kill to escape, only for that round at least.
I've killed a few kids in here without Quirks.
It has Tiers based on the amount of Quirks you have, weapons and your ability to fight.
As I've just received my first Quirk I'm in the next Tier.
Single Quirk Tier.
A year passes and I quickly become recognised as a strong competitor.
I use my Perfect Pitch to use my high frequencies to knock my opponent off centre or cause them to be nauseous.
I also became rather good at hand to hand and dodging attacks with misdirection. Of course... I did get hurt a lot before I got good enough at it but that just added incentive to master it.
2 years pass, my next experiment was a Yaka Arrow, it works well with my Perfect Control Quirk and I advance to the Single Quirk Weapon Tier.
At first I couldn't control the Yakka Arrow in any way, I was told it controlled by whistles, though the doctor couldn't figure out just how it worked. Depending on the tone and intensity of the whistle, the speed, strength, and direction can be controlled, but I took a while to figure out my mind didn't control the arrow, it worked better if I... Felt what the arrow wanted to do, and whistled accordingly to guide it where I wanted it to go.
I quickly became a monster in the Ring, feared by even the strongest because, no matter how strong you are, my Arrow can penetrate through your skin.
Another 2 years and I'm given another Quirk, Techno Adaption. I can adapt any technology augmentation I have.
My first thing was to increase the strength of the Yakka Arrow Controller, or the YAC for short. I improved the speed between my mind/whistles and the transmission to the Arrow to be so fast most Telepathy Quirks can't keep up.
I keep myself restricted, that voice in the back of my mind keeping me wanting to keep underestimated.
Then I did something I didn't mean to do.
I interacted with my own mind through the YAC.
I reactivated all my childhood memories and remembered Matt in clarity. Till now he was a blurry image, now I remember the addict who became my father figure, I cried for the first time in years that night before feeling my rage increase.
I'm going to avenge him... Then I'll make him proud by killing every Villain I can find who deserves to die!
For now though, I'll pretend to be 8362 for a while longer, I seem to be getting more Quirks... Hopefully my next one isn't too far off.
It was another 2 years before my next Quirk, a month before the procedure I lock my childhood memories away and all traces of knowledge to access them.
I undergo the experiment and afterwards feel my cells sing with energy.
"This is a Regeneration Quirk that can heal broken bones in minutes 8362. But it has the side effects of baldness and Pigmentation Alteration. You're now bald and blue with red eyes my boy" I look in the mirror he presents and smile.

"I like it Sir, the eyes match the YAC" I compliment, who? I don't know.
I know I'm a favourite of the Doctor's and find myself happy about that.
"Now, not many have reached the stage you're in right now, three Quirks, a weapon and skills like yours are incredible... You meet the Master today" I freeze in shock.
"Nobody gets to see the Master Sir... What's so special about me?"
"You are likely the only person besides himself who has more than two Quirks. Not a small achievement 8362" He presses a button and talks into it. "Kurogiri, open a Warp Gate to the Master, 8362 is ready"
"Of course Doctor"
A black and purple fog looking vortex appears and I follow the Doctor into it.
We come out into a darkened room, a man in a chair enshrouded by shadow with a lot of medical equipment is watching a computer screen with a smirk.
"Master, 8362 has survived the third Quirk and is ready for inspection" The Doctor bows, I copy him, if he bows to someone they obviously deserves respect.
"Rise, come closer to me 8362, allow me to get a good look at you"
I rise from my bow and step closer to him, feeling fear from his aura, but holding it at bay, it is wise to fear a man as powerful as he, but he may not like quivering wrecks.
His hands run over my face and I can tell he is blind, I can sense as he runs through every inch of my mind, seeing every memory, every thought, every idea.
"Hmmm... You are perfect, Doctor, you have done well with this one, use the remaining Yaka metal for Arrows, he is a diamond in the rough we must have at peak ability"
"Of course Master!"
"Thank you Master, for these compliments and gifts" I bow to him, he is a great man, and rewarding to those who deserve it.
"Please, call me Sensei, I feel under my tutelage, you will become perhaps... Even better than the successor I have been grooming, a worthy bodyguard to him"
"Your praise humbles me Master, I am eager to please"
"Return to the Bunker. I must begin planning your Training"
Without a word more I retreat, not turning from the Master back into the Warp Gate and back to the Bunker, the place I became who I am.
