Chapter 1

"This isn't right Kacchan" a young Izuku Midoriya says standing in front of a crying kid his friend Katsuki Bakugou was just bulliling.

"Are you really standing up to me Deku you quirkless Loser" Katsuki says hitting his hand well creating a small explosion.

"What your doing isn't right so I will stand against you" Izuku says

Katsuki looks over his shoulder at two of his friends giving them a smile. "Is this wrong guys?" he says. Both Shake their heads with smiles. "You see Deku there isn't anything wrong with this".

Izuku sees a large man with a blade coming out the side of his wrist, an evil smile coming toward them.

"Kac-" Izuku starts

"Shut up Deku" Katsuki yells, getting ready to charge. The man is behind the bullies with his arm pulled back ready to swing. Izuku runs at the kids, surprising them and pushing Katsuki out of the way as the blade comes down.

"Lets see some blood" The man says, slicing Izuku's left arm off right above the elbow. Before anyone can react Izuku loses his right leg below the knee, his whole right arm and left leg, his left ear and a little of the skull next to it, the man slashes out his left eye without damaging the skin or bone around it.

"Someone help" Katsuki yells as loud as he could seeing what is going on, making small explosions go off in his hands, scared for himself and his friend.

"Come on kid i am just having some fun" The man says taking a step forward onto Izuku's right chest crushing it from his neck to his hip and moving toward Katsuki well the other kids run away leaving the two.

"Stop there Villain" A man In what looks like a suit of armor with engine exhaust says as he runs onto the scene. Kicking the man in the back of the head knocking him out. The man sees Izuku still breathing somehow and picks him up looking at some of the people in costumes following him. "Secure the villain, I am getting this kid to a hospital to try and save him" The man says, taking off at max speed, being careful not to hurt the kid more.

"Yes Sir" One of the new men says well they go to put cuffs and bindings on the villain.

"Can one of you take me after them?" Katsuki says, wanting to be there if his friend dies.

"I can do it" A man in a set of armor like the first says. He Picks up Katsuki and races after the man with Izuku.

At the Hospital Nearby the Hero Arrives with Izuku and the boy is rushed to the emergency room at the heroes order even though the doctors are doubtful. Soon after, the man arrives with Katsuki.

"Where is Izuku?" Katsuki asks the man seeing him by a door in the hospital hallway.

"Ingenium is the villain Secured" The man asks.

"Yes the other heroes sent me as text including other crimes this man was involved in" Ingenium says

"Goo-" the man starts to say when they hear screaming inside the room behind him turning running into the observation room to see what is going on with Katsuki and Ingenium entering the room with him.

"What the-" Katsuki says, cutting himself off watching metallic black tendrils coming from Izuku's wounds latching onto machines in the room, piling them over and breaking them down and reconstructing Izuku's body with them.

The man walks into the operating room and looks at a doctor. "Please bring any electronics you can spare into this room for this boy's body to fix itself with. This has to be the boy's quirk trying to save him"' the man says and the doctors move around the hospital grabbing old and broken electronics that haven't been thrown away yet. Once in the room pretty much all the electronic devices are taken apart by the boy's black tendrils and making new Body parts and fixing his chest leaving a metal body and limbs that look like a mix of metal and metallic muscles. Soon Izuku sits up placing a hand on his head like he has a headache. The side of his head fixes the spot where a bump is there instead of his ear. Opening his eyes the new eye is gray with glowing green iris and a black center.

"What happened?" Izuku says looking around, noticing things seem clearer for him.

"You were almost killed by a villain if it wasn't for your quirk you would be dead" The man on the armor says.

"Quirk," Izuku says with a smile spreading across your face.

"Where is my baby?" A woman with green hair runs into the room, seeming really distraught.

"Aunty Inko He is over here" Katsuki says pointing at Izuku.

"Izuku," Inko says, running over and clinging to her little boy.

"Mom, I got my quirk," Izuku says smiling. Anko looks at her little boy past the tears seeing the new body.

"How did this happen?" Inko says, looking toward the doctor who looks like he is in charge.

"After arriving we brought the boy into this room to save him" The Doctor says. "As unlikely as it was" The doctor says so quietly only the heroes next to him could hear. "His body started sprouting tendrils and grabbing Electronic equipment and assemulating them" The Doctor says.

"What does this mean?" Inko says.

Before the doctor can talk another doctor comes into the room and hands him a file and leaves. "Okay. so it seems there are tiny robots in your son's blood which explains everything apparently your boy's quirk is nano machines, with them his body reconstructed itself and can probably add more electronics to him" The doctor says.

"This is a great baby," Inko says, clinging to her baby "You can follow your dream like you want".

"All good with that but we need to discuss how this is going to be paid for." The Doctor Says, a little sad about bringing down the mood.

"Oh well how much will it be?" Inko says, a little scared.

"One-" The Doctor starts to say, Looking downcast for the family.

"Don't worry about it i will cover it as an apology for not making it earlier" The Unnamed hero Says cutting the doctor off.

"Really" Inko says Looking relieved. "I don't want to incovents your family"

"Don't be ridiculous, my family is well off and can afford it" The Hero says, pulling the doctor out of the room Ingenium following them.

After a couple tests and checking on Izuku to make sure he is alright and there is nothing obviously wrong with the boy, they are allowed to leave after Inko signs some paperwork to check them out and update her son's quirk registry.

"You boys want ice cream," Inko says, walking out holding Izuku's hand as Katsuki walks next to him.

"Yah," Izuku and Katsuki say Together as they get into Inko's car.

Years later in a classroom.

"Okay so i am supposed to hand out these career Aptitude tests but" A Blond teacher says tossing them up. "We all know you all want to go into the hero course" the room gets loud as all but two kids start using their quirks. "Okay yeah you all have great quirks but no quirk usage in class".

"Hey teach, don't put me in with these wannabe D Listers most of them won't be more than sidekicks" Katsuki says giving an extremely cocky smile.

"What do you call Katsuki?" One student says.

"You think you're better than all of us," Another says.

"Your grades and quirk are excellent so Maybe you will get into UA" The teacher says

"He is going to the national school" A Different student says.

"Almost no one gets into that school" Another says.

And that is why there is no place better for us" Katsuki says, walking across the classroom, laying his arm across the back of his only real friend Izuku Madoriya, giving the class a smile. Izuku looks down and away, never getting used to the attention after awakening his quirk.

After school Katsuki and Izuku are getting ready to leave.

"You need to work out more Deku," Katsuki says, walking over to his friend who looks physically weak even with the robotic parts.

"I know Kacchan I Just got too caught up in studying and researching Heros" Izuku says standing up being a little shorter than Katsuki.

"Not a good excuse Deku, you want to get into UA and your physical strength enhances your powerful quirk. The stronger your body, the stronger you quirk is, remember" Katsuki Says pointing at Izuku.

"Let's just go Kacchan, we can pick up some weights on the way home," Izuku says placating Katsuki.

"Good your promise to use them" Katsuki says

"Yeah I promise I will start working out" Izuku says. Both of them start to walk home.

At an underpass the pair start to pass under when they see a green sludge coming out a manhole cover.

"Oh, Two Decent Flesh suits" The Sludge villain says, lunging at the two. Katsuki uses his quirk to blast to the side and Izuku lunges to the side dodging the villain.

"Kacchan go find a hero to stop this guy" Izuku says a couple plates coming from his body covering his mouth with a filter and his ears and nose seal.

"Got it Deku Don't die you Damn nerd" Katsuki says, seeming annoyed with his friend and leaving. The villain strikes at Izuku hitting an arm Izuku raised to defend starts to move around his opponent to try and find an opening.

"No need to fear" A booming voice says startling Izuku and the villain and they turn to it seeing a giant man with blond hair and a smile that says he isn't scared. "Because i am here" The man says, swinging a fist well, grabbing the boy to keep him from flying away.

"All Might" Izuku says, freaking out and digging through a bag. All Might somehow shoved the whole villain into two bottles.

"Yes young man I am All Might" The blond man says in his booming voice placing the bottles into his pockets seeing the boy's mouth, ears, and nose uncovered to look somewhat normal.

"Please sign this," Izuku says, holding out a notebook.

"No problem my boy" The man says, seeing the first two pages empty and signing them big, leaving a picture that looks like his eyes and hair with it.

"Can I ask you a quick question?" Izuku says.

"I Don't have Time sorry" All Might says getting ready to jump.

"Can I" Izuke starts All Might already Jumping away. "BE A HERO" Izuku yells after him hoping he could still get the answer even with everyone telling him he can do it he wanted his favorite hero to say it.

With All Might.

"Oh that is what he wanted to know, if I see him again I will tell him he can" All Might Thinks not noticing the bottle in his pocket slipping out a hole in his pocket.

With Katsuki

"Where are the Heros?" Katsuki yells as he runs down a street when a bottle hits him on the head and opens behind him. "Who is throwing things out their window?" Kasuki yells, stopping to rub his head.

"Oh the other Flesh suit" The villain says Jumping onto Katsuki trying to enter his body threw his mouth with Katsuki using his quirk and clenching his mouth shut trying to get free. "It will only hurt a moment don't resist"

With Izuku after a few minutes outside a crowd with an area that looks like it is on fire beyond.

"What is going on why aren't heroes doing anything" One Civilian says

"That thing has a hostage and they apparently don't have a quirk that could help" Another says

"Isn't that the villain All Might was chasing" Another says

"All Might Where is he there isn't any way he could have lost" Another says. With that Izuku pushes easily through the crowd seeing Katsuki's hair and before any more thought he runs forward past the hero line.

"Wait no Deatharms stop him" A hero with a bird mask says as Izuku passes.

"He is too fast" Deatharms says missing Izuku.

"YOU AGAIN" The Villain says, sending an arm of sludge at Izuku. Izuku dodges to the side and tosses his unzipped bag at the villain, having things hitting the villain in the eyes. Well the villain is recoiling from getting hit in the eye. Izuku makes it to Katsuki, grabs his arm and pulls back jets of fire coming out of the bottom of his feet, sending them both back.

"Get the kids away from him" Deatharms yells moving forward as something passes him.

"I keep getting you caught in my hero work with this villain" All Might says appearing in front of the boy's arm back ready to punch. "Detroit Smash" All Might Says throwing his punch making the villain splat around the area. The boys are taken aside by the heroes to parise Katsuki and Praise and Scold Izuku. All might look over to them without letting the press surround notice.

Later after Katsuki and Izuku Separate to go to their separate homes.

"I am here" All Might says Appearing in the interaction in front of Izuku.

"All Might why are you here" Izuku says

"I heard you earlier and saw you run into the area so i came to answer your question and ask one of my own" All Might says.

"Okay" Izuku says

"First I believe you can be one of the best heroes," All Might says. "Where do you plan to go to high school?".

"I am applying for UA," Izuku Says.

"Then let me train you for the next ten months" All Might says looking at the boy he hopes to make his successor.

"Yes," Izuku says, not wasting any time.

"No hesitation I like That" All Might says smiling wide.

A few Days Later

"Hello sir, have you seen All Might around here?" Izuku says to a man standing facing a beach covered in trash.

"Oh I am Toshinori Yagi, All Might sent me to watch your training and take notes for him" The Man says, pulling out a piece of paper and handing it to all might.

"Young man I am sorry to say but I am a busy hero. I am leaving Yagi to watch you train in my stead. He has a training plan I made for you to use if you can complete the training by the time i will Meet you, and when i do i will have another question for you good luck young man" The letter says.

"You have a long way to go –" Yagi says stopping to realize something "Um All Might didn't tell me your name"

"I don't think he asked me it," Izuku says, seeing Yagi rubbing the back of his head embarrassed for some reason.

"So what is your name" Yagi says

"Izuku Midoriya" Izuku says

"Well Young Midoriya Let's have a talk All Might forgot to ask you about your Quirk" Yagi says "I plan on working with him to change it after finding out your quirk today" Yagi Says after a pause

"My Quirk is Nano machines. I have tiny machines in my body that will heal wounds with mechanical Parts. If I come in contact with a new Electronic item I can assimilate it to gain its abilities, The nano machines can also reinforce my bones and muscles well fighting to make them stronger. The more I work out and get stronger the stronger the nano Machines make me. I also record everything I see and hear and it is stored in my head somehow without a limit. Also this" Izuku says, finally taking a breath pulling his shirt up open what looks like a door on his side pulling out a water bottle.

'Um you have a fridge on your side" Yagi says Confused.

"My mom bought a mini fridge for me to test my quirk on before i started earning my own money" Izuku says

"Earning your own money" Yagi says

"Yeah Accidentally assemulated my computer when young and have the full capability in my head i used some saved up allowance and started investing" Izuku says "And doing commission drawings of heroes for people" Pulling up a Drawing on the screen that appears showing a All Might in a button up white shirt gray slacks walking a Big white Dog.

"That is a good drawing," Yagi says, impressed.

"That was a commission from two days ago i refuse lewd Pictures no matter how much people offer i also make drawings of them in different heroic situations or working with different heroes" Izuku says

"Um if I am not overstepping how much do you make" Yagi says slightly interested.

"Last month was a slow month for both but i still brought in 1 million yen" Izuku says

"Then you're not being a hero for the money," Yagi says, giving a proud smile.

"Yeah i have more than enough to live on if i wanted to even without the commissions" Izuku says

"Back on top, pick what you have assemulated and what do they do,"Yagi says, realizing they got off topic.

"Oh right. Well there was the mini fridge which gave me this door on my side it also seems to just refill itself without me needing to put anything in it also it just has whatever i want at the time in it, it also gave me a cannon that sends out freezing air" Izuku says His right hand at the wrist splits open and opens to have a the area get super cold and form come ice on the ground. "It gets colder than that but this is good enough for a demo. The computer gives me access to the internet, text documents, games, and anything I could do with a computer. A hair dryer gives my cannon the ability to switch it to heat. A laser pointer gives me a laser cannon mode. A speaker can play sound from my shoulders and a sonic cannon from my arm like the others. A airsoft gun giving the ability to shoot pellets out my wrist." Izuku says his right wrist popping up showing a couple holes in it. There are a verites of things with propellers, jets and other small things for mobility. Also a deployable flotation system if i need it in water" Izuku says finishing his talking.

"All very impressive anything else your quirk does" Yagi says getting excited at the possibilities with this kid.

"I can absorb more than one thing and its mass gets stored somewhere no one can figure out where it doesn't even make me heavier so it is weird but I think it turns to pure mass somehow where it makes pellets and the drinks I pull out of my fridge. I will probably absorb all the Electronics on this beach to make sure I don't run out of mass even though I don't know how much I have. Also my eye" Izuku says, pointing to his mechanical eye. "Has a high speed camera, thermal camera, X-ray Camera, and a couple other options that aren't as notable" Izuku says.

"Um, is there a reason for the X-ray camera and how does it work?" Yagi says try to understand things.

"Oh when i awakened my quirk i was badly injured and my quirk assemulated medical equipment to save me" Izuku says "And for the use i can see peoples bones"

"Okay you said your mechanical body gets stronger the more you work out" Yagi says

"Yes it is a 10 times normal gain rate so I get stronger faster and have no strain on my body beyond normal strain for the workout" Izuku says

"Then why do you look like you never work out" Yagi says

"Um i get easily distracted with studying and quirk research" Izuku says

"Quirk research?" Yagi says. At this point Izuku starts Mumbling about a random hero's quirk. "Impressive," Yagi says, pulling out a packet.

"What is that" Izuku says

"This is the workout plan All Might gave me. The end goal is for you to clean the entire beach" Yagi says, handing the paper over. "Also you can't Absorb any of the electronics until the end of the day and only what you were able to take off the beach"

"Understood," Izuku says.

10 Months later the day before the entrance exam

"Okay here is the last bit of trash. This is the end of your training. Let's see if you can list these two things," Yagi says, looking at the cab of an 18 wheeler and its trailer.

"Lets see," Izuku says, stepping forward, reaching down and picking the cab up and walking with it and setting into the parking lot of the beach.

"Good" Yagi says watching Izuku move the trailer.

"It is thanks to you and All Might for the training plan" Izuku says

"It is your hard work and keeping to it that got you here" Yagi says

"So when will I see All Might" Izuku says

"Well you have to promise you can keep a secret first" Yagi says rubbing the back of his neck nervously

"No one knows I was offered training by All Might so I think your secret is Safe with me" Izuku says annoyed.

"Well then" Yagi says and then bulks up in front of Izuku "I am here young Madoriya"

"All Might" Izuku says confused.

"Yes" All Might says deflating to his small form.

"Okay what is this about?" Izuku says, giving a calm exterior even though his mind is running a mile a minute.

"Well I got this injury about 6 years ago" Yagi says pulling his shirt up showing a bad wound on his side. "It took my whole stomach and one of my lungs"

"6 years ago the worse villain you fought back then was toxic chainsaw but he never could of done enough damage with one hit to do this" Izuku says

"Your right about that the fight that did this was never made public. I pulled a lot of strings to do that" Yagi says. "As of right now i can only do about three hours of hero work a day"
"Then how long till you don't have any time" Izuku says

"I don't know that is why I have been looking for someone to be my successor" Yagi says

"So you think I am worth taking your title" Izuku says, honored by the thought.

"Not just that but also my quirk" Yagi says, spreading his arms wide in a showman way of trying to make it seem important.

"Um how does that work?" Izuku says Tilting his head to the side trying to figure things out.

"One aspect of the quirk is to pass it onto another, another is power storage. The main part that answers your question is my quirk can be passed on. I am the 8th wielder but I need to warn you I don't know how it will combine with your quirk. My master, the previous wielder, had a quirk that let her float. When she gained it, her float was also able to create propulsion and fly. The first time she ran into a wall and went to the hospital with a broken arm." Yagi says

"How did it fuse with your original quirk" Izuku says

"Oh well before this quirk I was quirkless" Yagi says Seeing Izuku's outer wall break and he starts pacing and muttering faster then he can understand "Stop freaking out" Yagi says chopping Izuku on the top of his head.

"Oh okay also what is the quirks name?" Izuku says, still obviously on edge.

"It's name is one for all" Yagi says "So what do you say Young man will you accept it or not"

"I accept it but would it be unfair if i accept it before the entrance exam" Izuku says

"If you are worried bout that limit yourself and only get a certain amount of points in the practical" Yagi says

"How many points should that be" Izuku says

"I got 108 in my exam" Yagi says thinking "Aim for 110 there will still be more than enough points to go around that way"

"Sounds good to me" Izuku says "But why me I have confidence issues and there are probably hundreds of people more worth than me, and what if i fail and don't get to be a hero and the quirk goes useless in me" going on and on getting quieter and quieter until Yagi can't understand them.

"Your doing it again" Yagi yells getting Izuku's to calm down

"Sorry" Izuku says

"Well you earned this all those months ago and completing the workout plan made this your reward" Yagi says pulling a hair from his head growing to his full form. "Eat this" He says, holding the hair out to Izuku.

"What" Izuku says

"You need to take in some of my DNA. This is more hygienic than blood so just eat it. '' Yagi says shoving the hair at Izuku who takes it and eats it feels weird.

"Gross" Izuku says

"Well now that will do it for now" Yagi says

"Yeah any advice for the exam" Izuku says

"For a Hero like you I say you will have no problem" Yagi says as the two walk up to the parking lot and Izuku walks over to the 18 wheeler placing a hand on it and it starts to go into his hand until it and its trailer are gone. "You might want to look into what the stored mass could do for you, what if you could make vehicles and things with the stored mass," Yagi says, getting into his old pickup and driving off.
