MIDORIYA RESIDENCE/IZUKU POV

I jolt awake feeling a strange feeling in my arms, looking down I see nothing strange. Looking around the room filled with my All Might Posters my eyes landed on my All Might Calendar, MY BIRTHDAY, YES! Today is my Fourth Birthday meaning I'll get my Quirk! Jumping out of bed I run out of my room and head to my mum's.

"Mummy, Mummy! It's my Birthday!" I yell as I jump on to her blanket clad body.

"Mm, what's that Izu? It's cleaning day?"

"WHAT!? No, Mummy it's my Birthday!"

"Oh, is that today?" She says smiling down at me.

"Yep, and today I'm going to get my Quirk!"

"Well let's go get some breakfast first. Go wait in the kitchen, I'll get dressed and we can have some watermelon, 'k?" I nod my head, mm watermelon. I ran into the kitchen and got the watermelon from the fridge and put it on the bench before pulling the stool I use to help mum with the dishes and dinner over. Standing on the stool I licked the drool that was rolling down my chin at the sight of watermelon. Waiting a few minutes, I noticed mum was still getting ready.

"Hurry up Mummy!" Looking around I noticed the knife mum uses for cutting food and thought about how mum said I was too little too use it, but that was when I was three, I'm four now so I'm not little anymore. So I picked up the knife and was about to cut the watermelon when the stool tipped. A sharp pain came from my left thumb as I landed on the floor making a large thud sound.

"Izuku? Are you ok?" My mum called as she ran out with a present in her hands, however she stopped when she saw my hand. Looking down I didn't see anything strange, all four of my fingers were still there- wait my thumb! Looking around I saw my cut off thumb next to my right hand as blood pooled out of my wound, just as I was about to cry out I was amazed as black threads came from wound and slithered across the floor until it reached my thumb and dug itself into the flesh before slowly retracting back into my body reconnecting my thumb to my hand, I was pulled from my amazement as I heard a thud and looked to see my mum faint.

DOCTORS/IZUKU POV

"Well Mrs Midoriya, it seems Izuku's Quirk is comprised of thousands of strands of a nearly indestructible wires. He cans use them in a variety of ways including reattaching limbs, we also discovered that the threads seem to be a type of symbiote."

"What does that mean?"

"They are semi-sentient and will protect Izuku without him having to tell them too. But now that we got that out of the way," The doctor turned to me. "It's time for the fun part, what are you going to name your Quirk Izuku?" I started thinking until I heard a whisper in my ear.

"Jiongu."

"Huh? Earth Grudge Fear? Why name it that?"

"It told me."

"What do you mean honey?" Asked my mum,

"My Quirk, it told me its name is Jiongu."

"It told you?"

"Yeah, it was like it whispered in my mind."

"Well it seems that Jiongu is actually fully sentient. Amazing. Very well Izuku, from today you are now the wielder of the Quirk Jiongu."

TWO YEARS LATER

When I went back to Day Care I told my friend Kacchan that I had a Quirk but I didn't show him, or anyone really because the Quirk Laws said I can't use it in public, as such Kacchan began to bully me calling me a Quirkless and useless Deku. It didn't matter though because Jiongu was there for me, it even began giving me lessons on how to use itself. In fact, the last two years I would train in my room with Jiongu, I learned that I could use Jiongu to capture stuff as well as make objects from it like shields. It also told me that I could shoot my limbs by putting stitches in certain places allowing them to extend with the threads keeping my body together, after putting Jiongu stitched on my wrist and forearm I learnt a move I called Jiongu Smash, just like All Might!

Today mum and I went to the shops to new the new All Might Figurine, but when we went inside I got lost so I headed outside and waited by the entrance. Suddenly I was pulled into the alley next to the store and came face to face with a tall man. He wore a white singlet and long brown cargo pants.

"Hey kid, you don't mind if I kill you right?" His sudden question shocked me so much that I didn't see the lava forming at his feet nor the glob of lava he was preparing to throw at me, no all I could see was hundreds of Jiongu threads come out of my chest and pierce into the man's chest. All I could hear was his pained screams as Jiongu sifted through his chest cavity before pulling out a beating... heart. All I could feel was my own chest cavity open up as the threads bought the heart into my own chest. Then I couldn't see, hear or feel anything.

HOSPITAL/IZUKU POV

"Don't worry ma'am, he won't be charged for anything seeing as it fell underneath self-defence laws but I would suggest sending him to a therapist, not many kids can cope with the thoughts of killing someone." The voice vanished and in its stead was my mums.

"Thank you officer." Then that voice was replaced by a familiar whisper in my head, Jiongu.

'Stole his heart? Was does that mean Jiongu? Wait I have his actual heart in my body!? A mask? I can do what now?! Wow, thanks by the way Jiongu. Well for saving me, that's why.' Soon the whispers faded as well as the darkness disappeared and was replaced by the white of a hospital room.

"Izuku!"

"Mummy...?"

"I'm here baby, everything is going to be ok." The next day I learnt that I was attacked by a villain but thanks to Jiongu's sentience it protected me without my command. That being said Jiongu had told me some stuff about itself including two new abilities. The first was that Jiongu was capable of taking other people's hearts and by doing so I have access to that person's Quirk and their memories on how to use it. This ability came with another perk, as long as I have more than one heart I can't die, instead the only way I can is for all of my hearts to be destroyed. Decapitation and bisection cannot cause my death either because I can stitch myself together. The other ability it explained was that by placing masks on my new hearts I can create external bodies of Jiongu that have the abilities of the heart it works of. So the next week I bought a metal wolf mask coloured black and an openable mouth, once I got back into my room I started following the instructions Jiongu whispered into my head. Disconnecting my left arm at the elbow I summoned a large amount of threads before pushing my second heart into the mass of threads. Suddenly the mass grew by twice its size before disconnecting entirely from my body after I placed the mask on it. The mass began moving and shifting as it transformed into a large wolf like creature with the mask acting as its face, the only difference from a real wolf was that it was a lot more front bulky. With the mask, its build and its Lava Quirk I named it Cerberus, King of the Hell Hounds, or Cerberus for short. After appreciating Cerberus, I began to will the threads back only for the mass to slide to my left shoulder blade before opening my flesh and closing after everything except for the mask was inside again, this however left the wolf mask sewn onto my shoulder blade with a large stitch like scar. Great now mum's going to freak next time she gives me a bath.

As the years went by my control and ingenuity with Jiongu increased till I could pull of some pretty amazing feats, I could make wings that I could fly with as well as making thread armour around certain parts of my body I could even create extra limbs and tail. I had also started taking sword play lessons after learning to turn the threads into blades and swords, I would also spend afternoons at the abandoned and trashed Dagobah Beach where I practiced my other lava Quirk which was called Vesuvius and combos with Cerberus. That being said as I went through Middle School I was constantly bullied by Kacchan and other pupils in my classes, luckily my teachers all had records saying I did have a Quirk otherwise I fear they would join in my ridiculing. But today was the end of all that, my last day before I finish Middle School, after that is 10 months and an entrance exam then I'll be able to use my Quirk at a hero school. See ever since I could remember I had always dreamt of being a hero but after watching All Might I realised that I didn't want to be just a hero, but a hero that saves everyone with a smile, a Symbol of Hope.

"DEKU!"

"LE EEP!" An explosion rocks my desk and seat sending me backward on to the floor of the classroom. Looking up I'm met with the view of a snarling blonde.

"You think you can go to UA? You think you can beat me? YOU! CANT! YOU'RE! QUIRKLESS!" You know what I'm really starting to hate this whole Quirkless thing.

"You really want to go to UA? Than take a swan dive of the roof and pray to be reborn with a Quirk, do everyone a favour and just disappear. I can't help but think how happy Aunty Inko would be with her disgrace of a son gone."

'LE FUCK DID THAT ASS HAT JUST SAY!! THAT'S IT HE WANTS PROOF I'M NOT QUIRKLESS THAN LOOK AT THIS FUCKER!!' I summoned three threads of Jiongu and shot one at all three of their legs before hanging the upside down.

"Say that one more time Katsuki and I'll make sure you can't attend anything without a wheel chair, got it?!" Before he could answer anything I threw them a god ten metres away into a tree, once they got up the two goons ran as fast as they could be leaving a bewildered and furious Pomeranian motherf@#*$%.

"WHAT THE FUCK WAS THAT!?"

"That was my Quirk dumb ass."

"BUT YOU DON'T HAVE ONE!"

"YES. I. DO! I told you when we were four dip shit!"

"THAN WHY DIDN'T YOU EVER SHOW ME BEFORE?!"

"Because it's illegal to use your Quirk in public you Pomeranian looking fuck!"

"DON'T CALL ME THAT!" He screamed as he jumped at me while charging up an explosion but much to his surprise I simply swatter him from the air with Jiongu and made sure he landed in the Koi Pond before leaving school.

I continued my way home while mumbling about that idiot Kacchan, in fact I was so mad I didn't even notice the underpass I walked underneath nor the rumbling ground and finally I didn't notice the green slime covering my body. However, the evil chuckling did reach my ears and sent me into an alert state.

"KUKUKU! A new host just as I needed!" I Looked around and noticed a giant wall of green slime with a face with large slimy tendrils hovering around my body ready to strike so in a quick and fluid motion I sent needle sharp wire from my skin at the creature's face and watched as it cried in pain as a few of my wires stabbed into its left eye.

"AHHH! YOU LITTLE SHIT!" He sent three of his tendrils at me which were blocked as I recalled Jiongu and formed a crisscrossed shield out of my Quirk. With the attack blocked I released a single thread from my back causing it to rip my shirt allowing me to summon out Cerberus, with my Jiongu creation out Cerberus summoned a large poll of lava underneath the Slime Villain, the heat given off began to dry out the villain until his surface bubbled and harden until all that was left a black crust of the villain. Suddenly though the ground shook so I prepared myself for another villain attack only to watch in amazement as none other than All Might jumped up from a manhole.

"I AM HE-" He stopped seeing the bizarre sight of the crispy villain, a thread wolf and my stich covered body.

"Umm... is it a weird time to ask for an autograph?"
