Hello, my readers, I am here today with a 3rd story!

This story is something that I've had on my mind for a long time. What would happen if I was Isekaied into MHA?

Now since the story that provided the final factor to making this was New Order, I apologize for any similarities (Purposeful or not) in this first chapter or any further chapters.

Well, if I were Isekaied into MHA, I would have to reveal my true name!

So Instead I am having an Isekai, of a character that is mainly based on me. But with other elements as well. Although he isn't me, so he won't make the same decision that I do in every scenario.

1: He doesn't have Anger issues. (Yeah, I kinda have anger issues, which is why most of my OCs have it too. Like Hunter in Let the Storm Begin. But he can still get angry. It just takes special people or things to make him angry)

2: He isn't random like me. (I tend to just do the first thing I think of, and not think too far ahead. This guy won't have that problem, he'll be time-smart)

3: He isn't wholly reckless (I like to think that I can fight anything, including bulls or lions, so for this guy to survive he'll need plans and not fair ones at that)

This character, is an anime fan, and is also very intelligent, but also not very picky. For the rest, you'll have to wait and see!

I Present MHA: All for None!

"Speach"

'Thought'

"Powerful voice/quirk affected voice"

A Line means a major scene change, the location of the scene will be at the top. With the exception of places, I don't want known.

Adrien cracked his back as he stood up leaving the soft confines of his bed, before quickly checking the clock on his wall, his eyes widening as he noticed the time, 11:00 PM. "Damn, 2 hours? That's a new record" he tossed the MHA manga comic onto his shelf alongside several other animes and mangas that he enjoyed.

The latest chapter had been the continued battle between Izuku and Shigaraki, a clash of pure strength and power.

Not for the first time, he wondered what it would be like to actually live in the world of MHA and thought aloud, "One for All, Rewind and New Order are all OP quirks. But I'd take All for One. Taking other people's superpowers is the most OP ability I can think of" he shook his head, "It won't happen either way." With another glance at the clock, he wondered if he should go to bed, or just read other mangas, but ultimately decided that his time would be best spent checking up on his friend.

Yes Friend. He actually had one, a girlfriend as well.

So sitting back down on his bed, he pulled out his phone and rang his friend, yet it automatically went to voicemail. That made him frown, his friend was in another timezone at the moment, so he should be awake right now, so he called again, and again, but he got no response. His frown deepened, concern slowly taking over. After what felt like hours his friend finally picked up.

"Hello?"

He froze at the feminine voice, his heart pummeling in seconds as a cold crept through his blood and clawed at his insides. It was his girlfriend. He shook his head, shaking off his fear, this didn't necessarily mean what he thought it did…

But…

Speaking in a deep voice he said, "Hello, do you have Mr Brooke nearby? Mrs…" "Mrs Brooke." He didn't even hesitate and hung up the phone.

It felt like the very room around him was closing in on him. His heart beat faster, his blood colder, his breath heavier.

His girlfriend was cheating on him.

He clenched his jaw and held back the tears that threatened to break upon his face. Taking a deep breath, he raised and lowered his hands repeatedly, calming himself down as much as he could. "Maybe some soda could help…" He muttered as he stumbled out to his fridge, to see a complete absence of any soda, soft drinks or fizzy drinks (Yes I know they are the same. Just making sure you all get that.) in his fridge. His shoulders sagged and he sighed sadly, "Guess I've gotta go shopping." He muttered, before grabbing his keys and leaving his house.

Most people turned to alcohol to drown their sorrows. But Adrien despised the taste of alcohol and never got used to it. Not even now would he turn to the mind-numbing beverage, nor would he try to end his own life.

As he walked towards the store, he stopped at the side of the road, waiting for the beeping of the crossroad to allow his passage when… "My Baby!" He looked up in surprise, and his eyes widened as he saw a Pram rolling down through the busy road. Turning his head he saw a truck fast approaching, and then his gaze shot back to the Pram, at this rate it was going to crash in mere seconds!

Not waiting to think, Adrien rushed forward onto the road, and leapt towards the Pram shoving it out of the way and back to safety, and a moment later everything went black…

?

"Self-sacrifice… Impressive… You better become a hero boy… or I'll deal with you myself…"

?

Adrien Hunt was an average boy of Australian, English and Dutch descent. Finally, the day came, and he learned a terrifying truth. He was Quirkless, Powerless, Useless. It was on that very day that he was orphaned by a villain.

And so, he would spend the next 10 years of his life living with his grandparents.

For a while, all was good, he went to school, and lived a normal life, but there was a fear in his heart, the fear of the villain from so long ago.

Then on his 14th birthday, the last he had was ripped away. For his grandparents were murdered, taken away by a villain just as his parents were. And he was all alone once more, hiding on the streets, hungry and tired, the scenes from the night before flaring in his mind. He hid and slept on the streets of Endo.

But when he woke, he was no longer Adrien Hunt. Instead, he woke up as another Adrien with the memories of Adrien Hunt. Most surprisingly, the world he came from bestowed upon him the knowledge to understand where he was, and where he is.

Endo

Adrien yawned as he opened his eyes, smacking his lips as he looked around before frowning. 'Hold up. Wait a Minute… Something ain't right'

Then the memories exploded within him, the past became known, and his eyes widened. 'I'm… in the world of MHA!' a grin grew on his face, yet as more memories came and went, that grin faded. 'Wait. Am I Quirkless?' The realization was heavy, yet it faded almost instantly. So what if he was Quirkless?

Like fucking hell was he going to let this opportunity slide by.

Standing up, he took a couple of deep breaths, 'If I'm Quirkless, that means I'm applicable for One for All. So this might not be too bad.' but as he stroked his imaginary beard, he noticed something about his hands that made him freeze. 'Are those… holes?' He stared in confusion at his palm, yep there were definitely small holes in them. But why?

Before he could pounder on it any longer, he heard footsteps behind him and spun around to see a middle-aged man with a knife in hand looking at him. "Pass over your valuables," the Thug said, Adrien's eyes widened once more and he stepped back holding his hands in the air, "I don't have any," he said, making the Thug frown, "Don't lie to me kid. Everyone's got something. So pass it over." The man then stormed over to him and grabbed him by the shirt before shoving him against the wall making him grunt. Adrien looked at the Thug, panic and fear quickly growing 'Shit Shit Shit! If I don't do something…' his mind raced as he searched for ways to escape, "So, you do got something huh?" The Thug asked, and Adrien gasped, "Your temperature is skyrocketing. And with Infrared vision, I can see it clear as day" the Thug explained, before shaking him, "NOW HAND IT OVER!"

Call him crazy, but when he heard the word Hand, something within him clicked and he glanced at his palms, and the holes inside them.

'I said I would have All for One… But could it?' acting on instinct, he put his hand on the Thug's forearm, and felt something he had never felt before, like a thread of energy. Focusing on that energy, he pulled and felt a rush of energy that settled within him. It was like he had a new limb, instinctively he could feel it, use it. At the same time, the Thug's eyes became dazed, and he let Adrien go before stumbling and eventually falling back. 'Did I… just take someone's Quirk?' Testing the new 'limb' he felt, everything suddenly changed into every colour of the Rainbow. 'Infrared Vision. I.. did it. I actually took his Quirk.' A smile grew on his face, as he began to chuckle. He had All for One! He actually had it!

He searched his body, searching for more Quirks, yet he only found two. All for One, and Infrared. 'So… I don't have the arsenal of Quirks that All for One had collected in canon. Oh well, with All for One, and my knowledge It won't take long for me to become absolutely broken' but first, he looked around and deciding not to take any chances, knocked the Thug unconscious with a well-placed right hook before running off. As he searched his memories, he smirked. The infamous Sludge incident hadn't happened to his knowledge, none of MHA cannon had. So he was before the events of Cannon. "-illain with a punch powerful enough to change the weather!" Adrien paused and glanced over at a nearby news podcast, which was depicted with photos of All-Might defeating the Sludge villain. "Spoke too soon." He muttered, so he had around 11 months before U.A began. He hummed thoughtfully, at least he wouldn't need to wait for too long for cannon to begin. But as he ran down the streets of Endo, a thought occurred to him. 'I'm nowhere strong enough to get into U.A with only Infrared vision, I need to find a stronger Quirk.' He slowed his pace and came to a stop inside the suburban district. He looked around, and his eyes widened as he recognized the building. Despair and anger both filled him as he thought of the horrors occurring within, and a plan already began to build within his mind to stop it.

'Looks like I just found the solution to my problem.' he thought as he walked away from the Shie Hassaikai compound.

He would wait for his chance. And he would take down the Yakuza group, and their quirks.

Endo

9 months until the U.A Entrance Exam…

Adrien sighed, his heart still heavy. He had been camping out the Shie Hassaikai for 2 months now, waiting for Overhaul to leave and walk around. Yet nothing.

Other members of the Shie Hassaikai had come and gone, but their Quirks wouldn't give him the edge he needed to take the rest of the Yakuza down, much less Overhaul.

But he wasn't just doing this for Overhauls Quirk, he wanted to free Eri as well. He wanted to bring down the entire gang in one swift blow, save Eri, everything. This wasn't just petty, it was thought out, by doing this he accomplished several things.

1: An incredibly powerful, and easy-to-use Quirk.

2: The defeat of the Shie Hassaikai, as well as all their Quirks.

3: The saving of Eri and the ending of the Quirk eradication bullets.

4: Shigaraki would never have the development or motivation that makes him worthy to be All for One's successor.

Yet, all of this relied on him taking down Overhaul. Judging from Overhaul's fighting technique in the Anime and Manga, he focused on his Quirk, meaning without it he would be weak and vulnerable.

He was broken from his train of thought as he bumped into someone, accidentally knocking them over. "Watch it" Adrien's head shot up and his eyebrows raised as he noticed who he had bumped into. 'Speak of the devil' he thought. It was Kai Chisaki, Overhaul.

Quickly dragging himself from his shock, he took the opportunity and reached out his hand to pull Overhaul to his feet. "Sorry about that. I was just thinking." Overhaul frowned, clearly unhappy to be knocked over, and slapped his hand away getting to his feet himself, "Watch where you walk next time. Some people might not be as forgiving as me." Adrien scratched the back of his head in awkwardness, "Yeah. Again Sorry." He reached out his hand again and waited for Overhaul to shake it. Yet again the villain didn't and instead turned around to leave. 'Damn it. I need to get my hand on him. Subtly failed, so I guess I'll need to go with the direct approach' As soon as Overhaul's back was to him, Adrien lunged at the villain placing his right palm on his back. Acting as quick as he could, the instant he felt Overhaul's Quirk, he grabbed it and took it.

Feeling the energy of yet another Quirk fill him, Adrien's grin became almost feral as Overhaul stumbled and turned around to look at him, a downright furious look on his face. "What are you trying to do?" he asked angrily, Adrien glared at Overhaul, "Take down the Shie Hassaikai, and free Eri '' he responded harshly, Overhaul's eyes widened. "How did you-" "Know. Easy, I've been watching. And I just got the last thing I needed." Overhaul's eyes narrowed, as he took off his right glove, "Can't have you going around and messing with my plans. Or Eri. Wasn't planning on killing anyone today, but I guess it can't be helped." Overhaul lashed out and grabbed his right shoulder, yet nothing happened. "What… Why isn't it working?" Overhaul muttered, to which Adrien responded, "I took your Quirk." Then before Overhaul could react, punched him square in the gut, making the Villain double over and fall to the floor with a groan. "What the? Hey!" Adrien looked over to see a staff member rushing over to them, looking at Overhaul with a concerned face. "I don't know what happened, he just fainted. Call an ambulance." The staff member nodded and rushed off again. 'Well that was easy.' turning around, he ran off towards the Shie Hassaikai compound.

Shie Hassaikai Compound-Endo

Adrien paused in front of the Yakuza base and pulled a gold coin out of his pocket. 'Good a time as any to find out how Overhaul works' focusing, he called upon Overhaul to activate the quirk, and then use it.

Before his eyes, the Gold coin was disassembled into flying rotating gold slivers. Commanding it to reconstruct, he smiled once again as the coin reassembled good as new. 'A simple, yet powerful quirk. It shouldn't take too long for me to figure out the rest of Overhaul's abilities. But first I need to take down the Shie Hassaikai.' Reaching out his hand, he placed it against the entrance of the compound, but before he disassembled it, he paused. 'Overhaul's greatest power is in its instant killing nature. But, I don't want to be labelled as a villain, and I don't want to risk being captured by the Shie Hassaikai. Although, Overhaul was able to put the boss in a comatose state. So I should be able to do the same.' Shrugging, he disassembled the door, its pieces instantly flying into the nearby area. Luckily for him, there were no thugs at the entrance. So he walked through the front door, to find the entire house abandoned. 'Huh. Abandoned. Okay.' He looked around for a while until finally coming across the secret entrance to the Yakuza base. 'Wish I remembered the passcode. But I guess I'll just use Overhaul' So after disassembling the fake shrine, he descended into the depths of the Shie Hassaikai Compound.

As Adrien walked around in the depths of the Compound, his confusion and worry only grew. 'What if they moved Eri?' It wasn't likely, but he couldn't help but worry. Even though, without Overhaul, they wouldn't be able to turn her into bullets…

'Without Overhaul, they have no use for Eri, she'll only be a danger to them. They could terminate her…'

The realization wasn't pleasant, he very well may hold Eri's life in his hands now. So he needed to act quick. "Who are you?" Adrien froze and instantly leaped away from the source of the voice, as his gaze landed on the villain, he narrowed his eyes. It was Mimic, one of the 8 bullets of the Shie Hassaikai. Mimic narrowed his eyes, "So we've got an intruder". Mimic glanced around, before running into a nearby room while Adrien quickly followed.

However, as Adrien entered the room, he noticed several things at once.

1st: It was a kitchen.

2nd: Mimic was gone, likely having merged with one of the appliances in the room.

3rd: Mimic wasn't alone. Rikiya was here as well.

Silence rang through the room for a moment, before Rikiya shouted, "Intruder!" and charged at him. Deciding to bite the bullet, Adrien didn't even move as Rikiya slammed into him and grabbed him. "Ha! Stupid kid didn't even try to dodge!" Rikiya boasted as he lifted Adrien up with his right hand, "Good job Rikiya, I was worried things were going to get ugly." Mimic said as he defused with the Oven. 'Morons, the both of them.' bending his wrists upwards, Adrien smirked as his palms touched Rikiyas right hand. "You should be more careful," Adrien said before he ripped Rikiya's quirk from him, and almost instantly used it against him, draining him of his stamina in mere seconds.

Adrien smirked as his body grew in size, his shirt being torn to shreds while his pants were stretched to the point of breaking until he stood just as tall and buff as Rikiya who looked at him in shock, "What did you do to me?" Rikiya asked, to which Adrien responded with a right hook to the face, sending the villain flying. "What?!" Mimic yelped as Adrien turned to him, and putting his hand on the ground, disassembled it. The ground was turned into violent ribbons that Mimic was far too slow to dodge or avoid. "GAAH!" Mimic yelled as he was thrown into the wall cracks spreading around him like a cobweb from the impact. Not allowing Mimic to recover, Adrien quickly grabbed the villain and just like Rikiya, took his quirk. Dropping Mimic to the ground, Adrien scoffed as he felt the power of the 2 new Quirks. Mimicry and Energy Suck.

'This is too easy. Which means somethings going to go wrong soon.'

Time passed, and Adrien continued to explore the Shie Hassaikai Compound, meeting and beating the 8 bullets as he did. Shin Nemoto was a joke, Toya Setsuno too. Soramitsu Tabe went down in seconds, and Deidoro Sakaki soon followed.

Confession, Larceny, Food and Sloshed were all added to his arsenal of Quirks. Then he went after the tougher opponents, Hekiji Tengai was next on his list, and with a combination of Overhaul and Sloshed Barrier was his as well. Kendo's Strongarm and Yu Hojo's Crystalize were soon to follow.

Adrien sighed as Yu Hojo fell to the ground at his feet, Energy Suck, Strongarm and Sloshed had completely decimated the final bullet. 'Combining Quirks is definitely powerful.' A grin grew across his face, 'Just imagine what I could do once I absorb even more Quirks!' the possibilities were endless, Immortality, invincibility. Adrien paused, 'shit, I can kinda see why All for One is obsessed with the more powerful quirks. It's easy to get lost in the possibilities. Need to watch myself.' Suddenly, Adrien spotted something in the corner of his eyes and immediately jumped back, narrowly avoiding the white arrow hair, which quickly retreated into the shadows.

"Impressive. You defeated the 8 bullets completely alone, and at such a young age. Tell me, boy, what is your quirk?" Adrien gulped as a figure emerged from the darkness, Chronostasis. 'At least I don't need to look for him. But I've gotta be careful, he hits me with his hour hand, and I'll be defenceless.' Adrien levelled a glare at the Yakuza member, "Why should I tell you Chronostasis? That would be counterproductive." Chronostasis chuckled, "I see you're quick of mind." Adrien deadpanned, "No, I'm just not stupid." Chronostasis raised an eyebrow, "Well, it doesn't matter, I'll know you're quirk soon enough." instantly Chronostasis' hair shot towards him, activating Crystalize Adrien coated his forearms with the durable substance, and blocked the arrows as he did. "Crystalize? How?" Chronostasis muttered in shock as he stared at Adrien, however, he shook it off quickly and attacked him again. This time Adrien summoned a Barrier to protect him, "And Barrier? Do you have a copy Quirk?" Chronostasis asked, but Adrien shook his head with a smirk, "Not exactly." then he activated Sloshed, and Chronostasis stumbled drunkenly, covering his arms with Crystals, Adrien activated Strongarm and Energy Suck together and with a yell drove his fist into Chronostasis stomach before unleashing a barrage of punches absorbing fragments of Chronostasis' stamina as he did, each blow more powerful than the last. Until finally Chronostasis was sent flying into the wall, unconscious before he even made contact.

Walking up to the villain, Adrien placed his palm on his forehead and took his Quirk. Feeling the energy within him grow once again, Adrien smiled. 'Mission accomplished. Now I just need to find Eri.'

It took a while, but eventually, Adrien arrived in front of a locked door. Pressing his palm against it, he deconstructed it, careful not to harm Eri on the other side. Entering the room, a sickening feeling filled Adrien's stomach as he saw Eri strapped to a chair, tears streaming down her face. "Who-who are you?" Eri asked, fear, sorrow and hope evident in her voice. 'Gotta be careful, Rewind's one of the most powerful Quirks in MHA, especially without any control over it.' "I'm here to help you," Adrien said gently as he slowly walked towards Eri. Eri's eyes flickered to the door and widened as she recognized the power Adrien held. "N-no! Please don't hurt me!" Eri shouted, struggling in her bonds. Adrien paused, before pleading with the girl "Please Eri, I'm not here to hurt you. I came to save you. They can never-" "NO! GO AWAY!" Eri shouted tearfully as her horn began to glow. And as an intense pain filled his gut, Adrien instinctively knew why 'Shit! She's Rewinding me!' throwing away any attempts at calming the girl down, Adrien lunged forward and placed his palm on her forehead, "Forgive me, Eri." He muttered, before taking her quirk.

Eri's back arched and her eyes turned white and her horn vanished, before she settled back down, unconscious. Adrien felt the power of Rewind flow within him yet he didn't smile, instead, the only emotion on his face was that of sorrow and remorse. "At least you won't suffer at Overhaul's hand anymore Eri," he muttered, as he freed her from her bindings, and caught the frail girl.

For a moment, he was tempted to use Rewind on her to restore her quirk, but he quickly dismissed it. Rewind was far too potent and risky for that, if he loses control there would be no second chances. 'I shouldn't keep Rewind. It's a hero's Quirk, not mine.' Glancing around, Adrien spotted a nearby phone, and picked it up, deciding to bite the bullet. After a quick internet search, he phoned the Nighteye Agency. "Hello, This is the Nighteye Agency how can we help you?" a feminine voice asked, speaking in as deep a voice as he could muster Adrien said. "Tell Sir Nighteye that the Shie Hassaikai have been defeated, and their plan ruined. You must also contact Eraserhead, as there is an innocent girl named Eri with an extremely dangerous Quirk she cannot control. I will leave behind all the evidence, as well as the Girl. I remind you, that Eri's Quirk is extremely dangerous and without Eraserhead, anyone nearby her is in extreme danger. A note will be left on her detailing her Quirk, and what must be done with her for her recovery." His message complete, Adrien hung up and dropped the phone. Then carrying Eri upstairs, he found a piece of paper and a pen, before writing down "This is Eri. She was tortured by the Shie Hassaikai leader Overhaul in an attempt to use her Quirk, Rewind, to eradicate Quirks by turning her into bullets with his own Quirk Overhaul. Her Quirk Rewind, allows her to rewind time itself on a target, she cannot control it and can rewind someone out of existence, the activation of her Quirk is marked by the glowing of her horn. She is to be taken in and cared for by U.A's Hero Course. Eraserhead is required to watch her for an early period of time, as he is one of the only ones who can stop Eri from hurting others. She is traumatized and fragile, so be slow and gentle while raising her. Raise her to be a hero, and make sure that she is protected."

After he ran out of space to write, Adrien shrugged, found some sticky tape, and stuck the paper onto Eri's chest, before placing his hand on her forehead and returning Rewind.

It was his first time giving, or returning a quirk to someone, and it felt strange. Like someone was taking blood from him, or sucking out his energy. Almost immediately, Eri's horn reappeared on her forehead, and Adrien sighed in relief, 'Good, she keeps the horn. Hopefully, she can become a great hero now.' Standing up, Adrien glanced around and left the Shie Hassaikai Compound.

As he walked around a corner, he glanced back at the building, where already Sir Nighteye and Bubble girl had arrived, and a small grin spread across his face. 'We'll meet again, Eri. Once I get into the hero course.'

And… there we go!

Chapter 1 is complete!

Originally this was going to be a 2-parter. But I realized that both chapters would be way too short for that, so I just combined them.

I apologize if this chapter was lame, or if Adrien was just too OP. I'll try to work on that. As for the Eight Bullets, I just don't really like them so I didn't spend too much time on them.

As for Overhaul, it was the only way for Adrien to get his Overhauls Quirk and is somewhat realistic. I plan to make things better going forward.

I gave Endo City its name since in MHA the city that the Nighteye agency and Shie Hassaikai compound are in are never identified or revealed.

So, Adrien Hunt, Owner of All for One, is in MHA and already making waves in its Plot.

Quirk Count: 13

Next time, we move into Cannon MHA! Lets go!
