Tiny Green Bean Lighting Machine

Chapter 1: The Start

I Am Back but with some bad and good news I am starting a new story and have officially decided to stop Green Spark, if you don't know it it was my old fanfic and I didn't really like where it was going I was attempting to change it but I still didn't like it but during that time I thought up a better idea that I could go with but anyways I hope you enjoy.

P.S Nothing Scientific I say here is true it is me completely bullshiting science so no plot holes exist hopefully.

Musutafu, Japan, Quirk Clinic

"Doctor as you've heard over the phone for some reason Izuku has stopped growing it's been a few months and hasn't grown since reaching 3 and I talked to other doctors and they said it might be quirk related " said a worried woman with forest-green hair while cradling a small greenish black haired child.

"Ms Midoriya I understand you are worried but calm down we just need to take a blood sample to see if it's a quirk and we will notify you when we find out but most likely it is a quirk side effect, speaking of which what are you and your husband's quirk" said the the doctor attempting to calm down the worried Mother.

"Well my quirk is semi-youth my aging process slows down and my husband's is a slight boosting quirk that boost his strength, speed, stamina, endurance and etcetera. But what does this have to do with Izuku?"Inko responded and questioned.

"Well you see a child can have either a stronger version of one of the parents quirk or a combination of the two, Izuku here most likely has a stronger version of your quirk Ms Midoriya."responded the doctor. "But moving on we'll need a blood sample to see if there is an active quirk gene and hope to see if his quirk might affect his growth."said the doctor

Inko made her way over to the clinic and was directed to the doctor's room, Inko opened the door and sat down waiting for the doctor to come in. The door opens to reveal the doctor.

"Ah yes Ms Midoriya, we have taken a look at your son's quirk genes and it comes out as positive so your son's quirk is active and it's as we've thought, Izuku's quirk is not allowing for him to grow but we don't know what it'll mean for his mental growth but we won't know for may be about a year or so," explained the doctor

"Wait so he'll be stuck at 3 for the rest of his life?" questioned the fairly worried Midoriya. "Yes, I'm sad to say he won't be growing up, oh and I almost forgot to say we'll need to check up on Izuku every 3 months or so to make sure he is perfectly fine," said the doctor answering Inko's question. "But how about his hair and his teeth because his hair has still been growing even with this quirk active and his teeth have also grown in," asked the overly nervous mother. "Ah yes natural growth of hair will happen but it looks like teeth probably not, oh if you're worried about Izuku not growing all his teeth don't worry it is his adult teeth, he'll keep growing till he has a full set but no teeth will fall out ,but on the other hand it looks like puberty will never happen we can get into details about this when he's old enough to be here and listen but most physical aging will not appear like body hair or facial hair and no growth in height but that's to be expected" ranted the doctor.

"Well that answers most of my questions but can he go to school doctor," asked Inko. "Yes but he'll have to avoid physical education and any physical exertion but I can provide that fairly simply," answered the doctor. "Well I have to find a way to break it to him" Inko thought to herself.

Midoriya Family Apartment

"Mitsuki I'm back now" said Inko as she entered her home. "Oh Inko you're back, I've been fine Katsuki and Izuku have been just playing in Izuku's room, so what did the doctor say about Izuku's quirk, is it why he hasn't grown" said Mitsuki. "Yeah uh… the doctor he said that Izuku has a quirk and it is responsible for Izuku's lack of growth but I don't know if I should tell him now and if I do when," said Inko as she sat down next to Mitsuki.

"Fine how about this once Katsuki gets his quirk tell Izuku about his because now isn't the time to worry them there just babies," said Mitsuki calmly. "But the doctors need check ups every 3 months" said Inko. "Well then let's tell him now and we can tell Katsuki as well" said Mitsuki trying to console Inko. "I just hope it'll go well with Izuku because I know he wants to be a hero but how can I let him go if his quirk keeps him as a baby and how would it even work with school," said Inko sadly. "What are you saying Inko if he stays as a kid he'll always be cute forever just be happy for now his quirk doesn't matter yet so just tell him me and Katsuki will leave you so you have your moment to tell him without my brat being too mean,"said Mitsuki. "You know what you're right I have to tell Izuku about his quirk whether I feel bad or not he needs to know,"said Inko. "I'll call Katsuki down so you can talk to him alone, KATSUKI GET DOWN HERE WE'RE LEAVING" yelled Mitsuki and in response. "COMING" yelled Katsuki as he ran down and Izuku followed.

After Katsuki and Mitsuki left Inko and Izuku were sitting at the table in silence for a few minutes till Inko said, "Izuku I need to tell you something" and Izuku responded quickly and said "what mamma", "Izuku you have a quirk-" but the instant Inko said that word Izuku was hyper with excitement and asked "W-what's my quirk mamma," "Well we don't know if this is your entire quirk but your quirk makes you stay 3 years old," "W-wait what mamma I'm not gonna grow big and strong like All Might" "I'm sorry Izuku but no you can't, I'm sorry Izuku, I'm so sorry." as she said her words she hugged Izuku sobbing.

A/N:So that was the first chapter, the next chapter will be Izuku's POV.

I would like to explain how Izuku's quirk will work so Izuku will stay at the physical age of three but every single day he is alive he gets a bit more stronger but the change is like in increments of lets say 0.1 and this is of his current strength so as a 3 year old and only after I'd say 3 months and a week I'd say he has a 9.7 strength multiplier but he is still only three so I say fanfic bullshit time his muscle will not ever change in shape so no buff baby but he'll still be strong as ever, it just takes time for him to figure out his quirk.
