A Useless Quirk~

Number One Hero and Symbol Of Peace: All Might. The hero, who makes everyone feel safe by facing villains with a smile on his face.

A young boy with a mop of green hair on his head is watching the video with an All Might figurine clutched in his hand. Even after watching it multiple times before, Midoriya Izuku's reaction is always the same. He watched the video with a huge smile and sparkling eyes.

"I will be a hero just like him when I grow up" Izuku declares with determination in his eyes. Suddenly, a puff of white smoke appeared and the green-haired child grew much taller with big muscles.

Midoriya Inko, who was cleaning her son's room while he watched the video, got startled due to the sudden transformation. After a few tests, they realized that even though Izuku was much bigger and muscular, he still had the same strength and the same weight, though his voice became slightly deeper. Being confused about the quirk, they realized that they would need some professional help with the quirk. So, they decided to have Izuku skip school the next day and get an appointment for a quirk specialist.

The next day, the two Midoriyas found themselves in 's office to find out what Izuku's quirk does. The doctor did a few tests, trying to determine what Izuku's quirk does. He then told the Midoriyas to wait in his office, while he goes and gets the test reports. After a few minutes of waiting, the doctor returned with a few papers in his hand.

"So… little Midoriya seems to have a kind of stockpile quirk, and the muscle form, as we are calling it, seems to be a way for his body to handle a large amount of energy," Tsubasa said with a frown on his face.

"Is there a problem?" Inko asked with a worried expression glancing at her son and then the doctor.

"Well, you see , although Izuku's quirk allows him to hold a lot of energy, there is no way to put energy into the quirk. And a stockpiling quirk without something to stockpile is pretty much useless" the doctor answered as he sat back on his chair.

The Midoriyas then left the hospital and went home. Izuku was quiet ever since he heard that his quirk was useless. And life would only get worse for him as the years go on. After finding his useless quirk, many children in his school started bullying him for it, though they never got physical, except Bakugou Katsuki and his goons.

This goes on for 10 whole years until one day everything changes…

"Young man, you too can become a hero"

The words spoken by All Might made Izuku collapse on his knees, clutching his chest and crying his heart out. Someone had finally acknowledged his dream of becoming a hero.

"I deem you worthy of my power" All Might declared with a smile on his face as he walks towards Izuku. The confused look on Izuku's face told All Might that he didn't understand.

Then All Might explained his quirk 'One for All' to Izuku and asked him if he would inherit it. He accepted without hesitation and All Might asked him to come to Dagabaoh Municipal Beach the next day early morning.

The next day, Izuku is seen on a beach full of trash, pulling on ropes tied to a fridge. A fridge that All Might is currently sitting on, making it more difficult than it already is.

" HEY HEY HEY! This fridge is pretty comfy to sit on! " declared All Might from on top of the fridge making Izuku groan and fall on his back from exhaustion.

"Why am I pulling trash on this beach anyways?" Izuku asked All Might. Not that he didn't trust the hero, he just did not see the point in pulling trash.

" That is because you aren't ready to receive my quirk" All Might answered with his usual smile.

"But that's not what you said before!" Izuku screeched, still on the ground.

" Calm down. I meant your body. My quirk One for All is a culmination of the strength of 8 people. With a body that isn't prepared to handle the strain, our limbs might pop off " All Might answered, a little too nonchalant while talking about losing limbs.

Izuku shuddered as he imagined all his limbs and head popping off right after receiving the quirk." So this beach cleaning is to prepare my body enough to handle your quirk?"

All Might nodded " Not only that, but this beach used to be a beautiful place, but now is full of trash. Heroes nowadays are only about defeating villains for fame and glory. But true heroism lies in performing community service like this !"

He then turned to Izuku " Young Midoriya, you plan on going to UA, correct? " he received a nod in reply, " As sad as it is to admit, getting into UA hero course without a quirk is nearly impossible without a quirk- " he gets interrupted by Izuku.

"That's another thing I wanted to talk to you about" All Might shifted to his twig might form. "On the roof, I wasn't really thinking clearly and ask you if I could be a hero without a quirk, but I do actually have a quirk. It's just so useless that I may as well be quirkless" Izuku said with a frown on his face.

"It's no trouble my boy, but it is good that you mentioned this now. One for All is supposed to enhance the user's original quirk as well, so no matter what it is it needs to be considered. Can you show me?" All Might asked.

"Right…" Izuku took a deep breath and got surrounded by white steam, similar to All Might's transformation. After the steam dissipated Izuku was at eye level with All Might in his regular form, with huge muscles, only rivaled by All Might himself.

All Might stared slack-jawed. After a few seconds, he finally spoke, "Uh, my boy are you sure that this quirk of yours is useless?" deep down he found it kind of funny that even without One for All, his successor already had a transformation like him.

Izuku let go of the transformation, and after some more steam became the short teenage boy that he was, though he was slightly panting from the transformation. "Well, you see, even though I look much stronger, I still weigh the same and have the same amount of strength as normal. The doctor said that it is a stockpiling quirk and the transformation is meant for me to handle the large energy output. But he also said that there was no way to put energy into the quirk, so it was useless" Izuku mumbles to himself and All Might, who was able to understand what Izuku said, by paying more attention.

"I can see how that can be considered useless, other than intimidation purposes…" All Might contemplated the new information for a few more seconds, "One for All is also a stockpiling quirk at its core, so your quirk may be very compatible with it and you may not need the training to make your body stronger. But I do not think that we should risk it and you should clean the beach anyways"

Izuku nodded enthusiastically, partly excited because his quirk finally has some use. All Might then hands him 'The American Dream Plan". After going through the first few pages, he closed the booklet with a sigh.

These are gonna be the longest 10 months of my life…

[Ten months later, on the day of the Entrance Exams]

All Might pulled up to the beach in his truck. It had been 10 months since his successor started cleaning the beach, and it all leads to today, the day of the entrance exam. He had been busy for the past few days and didn't have time to check Izuku's progress.

He was very shocked when he saw the entire beach spotless, and his successor on top of a garbage pile, screaming into the distance, shirtless.

"Oh… my… GOODNESS! " he exclaimed the last part by transforming into his muscle form. When Izuku fell from the top of the garbage heap, All Might was there in a second to catch him.

After taking a few minutes to catch his breath and admiring his own work, Izuku felt like he was flying in the sky right now.

" NOW! I think it's time for you to receive my quirk " All Might said while plucking a hair from his head and held it out for Izuku to take. " EAT THIS! "

"What?" Izuku said with a horrified and disgusted expression on his face.

" Well, you need to ingest my DNA to get my quirk. Now, there is no time, so EAT EAT EAT! " All Might said.

Izuku just sighed in defeat, took the hair, and ate it using water to wash it down. All Might then explains that his body needs time to digest the hair and that the power should manifest on time for the physical portion of the exam. So, Izuku went home to shower and get ready for the exam.

While eating breakfast, Izuku almost choked on his food as he remembered eating hair that same morning. After telling his mother that he was leaving, he made his way over to the station to board a train to UA.

Everything seemed to be going well. Izuku was able to board the train on time and would be able to get to the UA campus in time. He sighed. He was still slightly exhausted and sleepy. It wasn't extreme enough to hinder his performance, though it was a noticeable feeling and quite annoying. He just wished it would disappear somehow.

He snorted. Like that's actually possible. He thought. But, as if the gods themselves were listening to him, his exhaustion and sleepiness did disappear. He was shocked.

Maybe it's a sign that One for All has settled in? He mentally asked himself. He certainly hoped so, it would be more comforting to know that he has indeed received the quirk. But, of course, had no way to be sure...

After reaching UA, tripping on the pavement, and getting saved by a cute girl, Izuku went inside his assigned classroom for the written part of the test.

The test wasn't the hardest, but it was challenging, even for someone who may have an intelligence enhancing quirk. Though, Izuku was sure he did well enough. Even with all the training, he was still able to keep up with his studies. He made his way to the auditorium, already reading the pamphlet he was given, which had all the information about the physical exam.

Present Mic started explaining the practical exam, but Izuku wasn't paying attention. He was muttering up a storm about how he would use his quirk against robots. He wasn't sure if One for All had transferred or not. What if it still needed time? How would he pass? Would All Might be disappointed-

"And you! With the curly hair! You have been muttering this whole time! If you cannot take this seriously then I suggest you leave" a blue-haired boy sitting a few seats in front of Izuku yelled at him.

Now normally, Izuku would have likely stuttered out an apology and kept quiet. But today he was too focused on his quirks. So, he just ignored the boy and continued muttering about using his quirk.

The boy was about to continue yelling but was stopped by Present Mic who explained that the Zero-pointer was just an obstacle and three was no need to take it down. After that, the students were sent to change into whatever clothes they brought for the practical exam.

Izuku brought a green tracksuit that was very much oversized for his little body. Most of it was dragging on the ground behind him. If he brought the suit he normally used, then it would have gotten torn off the instant he transformed. And he didn't have ultra stretching material as other pro heroes have.

As the bus approached the exam center, Izuku only had one thought on his mind…

I should ask them to make my hero costume my size and ultra stretchable…
