Explosions rang out through the city, each one drawing Izuku's attention to it. The thought of new data driving him as he discarded the food he was carrying. Hopping from building to building, wall to wall, it wasn't long before he came across a crowd of people and heroes. Each hero was trying to keep the crowd back as explosions rang out and fire covered the area.

"A one lane street?! I need to at least two lanes to get through!" Mount Lady proclaimed as Izuku looked up to see her. Kamui Wood was pulling people back with his branches. DeathArms was catching or blocking falling rubble that was dislodged by the explosions.

Izuku, noting the heroes decided to peek over what crowd he could with a small hop. His eyes widened as he saw the same sludge villain who attacked him latching onto his frenemy, Katsuki Bakugo. Whispers among the crowd spoke of All Might and how he was chasing this very same villain. Public opinion on that rag of bones caused Izuku to shake his head.

Catching one final look at Katsuki through his hops, Izuku could see something he hasn't seen from the proud boy. A look of fear that asked for help, for anyone to save him. No noise, no reason, no idea why he jumped full strength to an uncovered wall throwing both his backpack and duffle at the villain. As he increased his speed by jumping from wall to wall, his backpack and duffle were blocked by the villain. Books from the backpack flew out slamming into the villains eyes forcing a scream of pain loosening the grip on Katsuki's mouth so he can gasp for air. "Get… off… of… me!" Katsuki screamed trying to blast the villain off only for his mouth to be covered again.

"Shut up kid! It'll be over in a moment!" The villain declared in a laugh unaware of the rabbit jumping at high speed around him.

A rather large smile crossing Izuku's lips as the tip of his right shoe caught fire and held despite the speed. "Keep that tone villain!" Izuku proclaimed as he came from above at high speed. "Rabbit arts…" His right leg raised above his head as he approached at high speed. "Luna Arc!"

The strength and speed of Izuku's kick came down on the villain scattering it long enough to grab Katsuki for an attempt to get away. Pulling him from the sludge as fast as he could, Izuku tried to get Katsuki away. "W-why did you come save me… damn rabbit…"

"You looked like you needed help." Izuku's comment rang in Katsuki's ear as he and Izuku were grabbed by the villain again. His body reforming much quicker than Izuku had anticipated. The heroes scrambled to try and save the boys as they were being pulled back into the sludge, unaware of the other party near them.

All Might and Tsukauchi were nearby as they heard the reasoning from Izuku. All Might gritted his teeth as he inflated himself once again. Now with conviction to do something he should've done before, Tsukauchi's complaints falling on deaf ears as he approached through the crowd and heroes. Hand grabbing onto Izuku and Katsuki as he pulled them free with great force, "Young Rabbit boy. You have reminded me why I do this in the first place. Be proud." All might declared pulling his free hand back to attack the still approaching villain.

"All Might!"

"Delaware…. SMASH!" All Might proclaimed uppercutting the villain to the best of his ability. The shockwave ripped through the alley and towards the sky causing a sudden funnel to form. Rain came down in a violent torrent as police cars and news vehicles began swarming the scene. Laughing aloud as he talked to the media, the police grabbed up the villain and placed him into a specialized box meant to contain him.

DeathArms scolded Izuku for his rough treatment of the Villain as well as the property damage he caused while jumping around. Katsuki on the other hand was praised from withstanding the villain as long as he did. Many of them offering Katsuki a position as a potential sidekick, but he didn't pay any attention to it. His eyes were filled with rage as he stared at Izuku who took a few puffs of his inhaler. Watching the young rabbit walk away, Katsuki gritted his teeth in annoyance and proceed to excuse himself from the mass of Heroes swarming him.

He couldn't believe that villain got the drop on him like that. The audacity was palpable to his pride that he just wanted to scream and explode in irritation. In his shameful walk, Katsuki kept kicking stones as his brain ran through any scenario he could. Was there a point he could have seen the villain? Was there a way to use one of his minions instead so he could get away? No that one was cowardly even more himself. Was there any keep sign that anything was going to happen?

No matter what his brain racked up, it was just climbing further and further down his personal rabbit hole. As he was walked, Katsuki was brought out of his haze by the sight of familiar white/red curly hair. His anger rising as he stood before Izuku glaring down at him. "You damn battle nerd! Don't think I owe you anything!" Katsuki declared as Izuku looked at him confused before flashing a small smile.

"I'm now eight ahead of you in our matches explosive Pomeranian," Izuku commented tacking on extra points just to irritate Katsuki further. The taunt seemed to work as Katsuki yelled that he didn't ask or want Izuku's help before walking off. The light shining just right as Katsuki walked away. Izuku still wanted to be friends with him if he ever unlocked his head from behind.

Turning towards the convivence store location, Izuku was now face to face with a walking corpse. "What is it All Might?"

"Do you know what all great Heroes have in common?" He began to ask as Izuku simply shook his head. "Before any sort of danger, they're bodies moved on their own without any thought or input. They ran straight into danger, not for fame or glory, but to help and save people. I saw how you used your quirk, a quirk that as of right now only one other person has that is similar. I saw you throw your backpack and duffle. I saw the strike you did to break that boy free. I felt your determination." All Might spoke as he trembled slightly, the thought of giving this child power that would enhance his quirk further. He would become a target for him of all people. However this would allow All Might to finally breathe a sigh of relief as he hopefully won't be pursued further. "Thus, I deem you worthy of my power. One person inherits it from another. They improve it and pass it on. The name of my quirk is… One for All."

Izuku couldn't help but snicker at the name. His mind thinking about the three musketeers. "Thank you but no thank you All Might." Izuku stated as All Might's face went slack jawed. As much as anyone who found out about All Might's quirk would take it in a heartbeat, Izuku could honestly care less. His mother was the one to teach and instill in him that even if people think a quirk is useless or weak, to prove them wrong through hard work and dedication. To hone the very quirk, they were making fun of into a weapon that was far superior than ever thought. "It's not that I'm not honored you'd tell me about this but I was raised to try my hardest with what I had." Izuku explained as All Might just sighed.

"That's fine. Let's make a deal then." All Might stood in his 'Muscle Form' again, "I will train you for whatever hero school you want to get in. But in exchange, when I can no longer carry on as Number One you have to take my place." All Might state as he watched Izuku begin to ponder his deal. He was already planning to offer training to someone with this raw amount of potential but there was an underlined portion to this. Izuku Usagiyama will become One for All's holder either in secret or he learns of it.

"I thought about it and going with a different 'trainer' than usual will be good for me. Break up much of my normal routine that I usually do in summer." Izuku commented as he looked towards the giant of a man again, smoke clearly coming off him. An indicator that the 'Muscle Form' All Might is using will run out soon. "However I was already aiming to be Number One, so my mother can be proud of what I can do. So I look forward to training with you All Might."

With this verbal contract between All Might and Izuku Usagiyama, something was set in motion that no one was prepared for.

-(Line Break)-

All Might returned to his two-bedroom apartment, completely drained from the day and his constant transforming into his muscle form. Unlocking the door, he could see two pairs of shoes in the shoe holder. Smiling, he sat down and began taking off his shoes.

Once his shoes were put away, All Might began walking towards the living space just beyond the kitchen and entrance way. The lights were on as laughter rang through the room as he opened the door. Inside the room was Hana Yagi, formerly Hana Shimura, laughing with one of her friends as they were studying.

"Oh? Dad, you're home late. Villain attack?" Hans asked All Might as he simply nodded at her assumption. One of the many reasons All Might was looking for a successor to One for All was Hana. She is currently a second year at Shiketsu High and following her dreams to be a hero as well as finding her missing brother Tenko Shimura. "You need to take it easy! Do you not remember what happened five years ago?"

All Might didn't bother to look since he knew what face she was making. It was one of disappointment and worry since he received this gut wound. It was nearly the same face she had when he walked past her at the hospital then. Frozen in fear and worry, terrified that her family would be lost again. If Sir Nighteye wasn't there, she would've forced All Might back into that bed and bound him for as long as was needed. "Hana." All Might inflated himself again, despite the strain he already felt. "Don't worry, I will always comeback. Right young Mirio?"

Addressing Hana's middle school friend, the boy simply smiled at All Might before declaring loudly, "Yes sir! Sir even said you will always come back!" The boy is named Mirio Togata, standing nearly 6'3" in height with blonde hair, blue eyes and a part of class 3-A of U.A. High school Hero Course. His quirk, Permeation, allowed him to pass through solid matter just by holding his breath. "Anyways Mr. Might! I was chosen at the start of next semester to be a part of the big 3 of U.A.!"

All Might's eyes widened at the news. To be a part of the big 3 of U.A. was very prestigious. One must be a part of the top cut of their classes, have done many internships and have already obtained a side kick position. Even then you are placed into a lottery-like system that all current teachers of U.A. must vote or veto. "Great job my boy!" All Might exclaimed in excitement as Mirio and All Might began talking about the hero world again, Hana simply listened.

All Might or Toshinori Yagi was the best person for her when she lost it all. Toshinori was patient with her as he would often wait with food by her door when she was younger. When the nightmares came, he was there in his muscle form holding her tightly. She couldn't count the amount of tears she had shed while in the man's embrace. He was there when she was sick, injured, terrified or frustrated. He was her father even if they weren't related by blood.

There were often times she thought of what the outcome could've been like if she and Tenko simply ran away or told that hero who helped them out when they were little. The image of the small boy with white hair and red tips playing with them and Mon. Happier days for sure as she focused back in to see Mirio and All Might waving their hands in front of her. "What is it?"

"Pizza?" Mirio asked as All Might held a coupon sheet so she could see it. Grabbing the family book, Hana looked to see if they had some spare money to use. Sighing in defeat she simply nodded to their request.

Hana could never win against Mirio or Tamaki when it came to their smiles or depressed outlook. Since she was always a little younger, Hana always hung onto them like elder brothers even if she started to see Mirio in a different light since Junior High.

-(Line Break)-

Takoba Municipal Park and Beach front, a once heavenly spot for the whole family, was now nothing more than a garbage dump for those who didn't want to pay the disposal fee for certain objects. Izuku's eyes were wide as he arrived since All Might left a message saying to meet here. "Why would we meet here for training?" Izuku thought aloud as he heard someone approaching from behind.

Turning around, he could see All Might in his muscle form towering over him. He was smiling at Izuku as he walked pass and approached an old refrigerator. "You asked why I asked you here for training. Simple. Heroes weren't always peace keepers. When the profession first came about, we Heroes were every day people doing our part for our community." All might placed his hand on the top of the fridge, "I know you rejected my initial offer but this is still important so you can control your strength and equalize your entire workout." In a swift motion he crushed the refrigerator sending a shockwave behind him clearing away the garbage. "You will spend the next 10 months cleaning up this beach. If you complete this and my All American Dream plan then I shall give you any reward!"

The declaration rang in Izuku's ears as a feral grin crept over his face. His red eyes shining with vigor. He has a chance to see how a true close quarters fighter like All Might in a potential sparring match. In addition he could use this chance to work each muscle and become able to hopefully beat his mother in the next match up. "Very well All Might. I'll take you up on that."

All might nodded as he pulled out a sheet of paper. On it was the All American Dream plan, All Might told him about. It consisted on 60 minutes of beach clean up, 1000 pushups, a thousand crunches, two kilometers run and various weight trainings. Izuku's eyes squinted at the old man standing near him smiling still. 'You still want me to take that quirk eh? Not happening.'

Month one, Izuku focused mainly on moving trash and training as All Might instructed. All the while he was making jokes of how he lost weight or was half the man he was before. His photo taking photos as Izuku complained and yelled at him for not being of any help

Using his legs to crush large objects into moveable cubes, Izuku would drag them across the sand. His feet digging in as the strain of his muscles cried out. Hamstrings roared with pain, calf muscles straining against the sand and even his lower back was telling him off for doing this. After getting it to the nearby disposal vehicle that All Might rented, Izuku would take a small breather and use his inhaler as needed. The small break gave his muscles a chance to rest for a moment before continuing.

On month three, Izuku began to add unnecessary workouts to the All American Dream Plan. Starting Month Three, the plan was set as one hundred push ups as well as squats and crunches. Following that was a long run of twenty to thirty kilometers to throughly work his body. However during this, Izuku began to do weight training at home and school to improve his muscles further than what the beach clean up could do.

By this point the beach was over half cleared of debris and trash. Among the garbage was a broken down white truck that All Might decided to fix up with Izuku's help. Laughing loudly as he began working on said vehicle, All Might would occasionally look to see his trainee trying to sneak away to continue cleaning. Grabbing the boy, All Might would go on a lecture on how it's important to know how to repair a car. The result of which had Izuku rolling his eyes as he could spring faster than most cars by using the moment built up from his quirk.

Month seven came around, the beach was clear of debris and transformed into something beautiful again. No trash in sight as a lone, rebuilt pier stood on the water with a toned figure standing there atop it. Izuku had followed All Might's instructions and ended up with a more toned figure to the point he looked like the male version of his mother, Mirko.

All might was quite surprised with how fast the clean up went. He personally thought they would be going until the last minute but here they were only seven months in and the beach was clear. 'Maybe I should give him some combat training, just to see where he stands. Just so we can see where his combat and damage control training can begin.'

All the while All Might didn't notice the feminine figure approaching from behind him. Her stride quickly picking up as she passed him at a high enough speed that he couldn't react in time too. Quickly the figure approached Izuku and swung her leg at him.

Almost instinctively, Izuku dropped to the ground and kicked the incoming leg. His body pressed firmly on the ground as he braced himself and pushed back. After colliding, the two jumped back as a hearty laugh could be heard from the woman, "Damn kid! Thought you would've rusted with how long I've been gone!"

Izuku smiled savagely as he glared up at the woman, her visage standing proud before him. "Sorry Mom, but that wasn't going to happen!" As if normal for the two, a high speed battle began as the pressure of each kick was scattering more sand and water. Among this All Might noticed Izuku's grin growing more and more viscous and battle hungry, almost the same as the woman he was clashing with.

Luckily for him, it didn't take long as the two separated with Izuku collapsing to the ground in fatigue and pain. His shins and calf muscles bruised as the woman, his mother, approached. "Damn boy, you actually bruised me for once. Good job keeping up on your kicks!" She laughed as she pointed at a bruise on her right thigh from where Izuku landed a kick as some point.

'That grin he was sporting…' All Might began to think as he crumbled up the new set of All American Dream Plans. 'It was like the battle fueled him more than actual training… should I encourage it or shut it down before he goes to far?' All might began to pace back and forth as he thought over how to approach Izuku's future training for the next two months. Mulling over each detail he could catch, he was wondering if Gran Torino, his old teacher, could quell such ferocity.

As he thought this, Rumi approached the man cautiously not knowing who exactly he was. He stood by and watched as she engaged in her battle with her child. For all she knew, this was a villain waiting to attack them. "Umm excuse me?"

Rumi's words knocked All Might out of his thoughts as he looked at her. Her body language was clear as she had a leg behind her, ready to kick if necessary. Putting his hands up, crumbled AADP (All American Dream Plan) still in his clenched right hand All Might showed he wasn't a threat as best he could. "I'm sorry. I was in thought. Can I help you?"

"Yes you can. Who are you?" Rumi asked her voice making a primal sound as she spoke, he legs tightening ready to strike.

Sighing loudly, All Might transformed into his muscle form smiling down at her as her leg loosened the tension it was building. "Sorry to make you feel threatened Miss. I am All Might! I have been training your son for the upcoming U.A. entrance exam." He explained hoping she won't pry too far into how her son and All Might know one another, even if it was futile in the first place.

"Izuku… how do you know All Might?" Rumi asked not bothering the tall man before her as her eyes locked on to her child who shivered in fear. "Did you do something you know you were not supposed to do? Again." She was now walking towards her son, eyes filled with rage as she came closer to him. "What was it this time?" She cracked her knuckles before knocking Izuku to the ground with a solid punch to the top of his skull. His face planting into the soft-ish sand. "Was it a purse snatcher? A robbery? Perhaps a murder investigation?"

All might seeing Izuku unable to answer cleared his throat to speak up for them both. "It was a sludge villain who attacked his classmate. One with spiky blonde hair and an explosion type quirk." Rumi, still furious at Izuku, nodded in understanding as her child pulled his head from the ground. Shaking his hair and ears as best he could to free up any loose sand before sitting on his knees.

"You saved Katsuki eh?" Rumi asked as Izuku simply nodded timidly. She sighed loudly before pinching the bridge of her nose. She was still angry he put himself in danger like that but was also proud that he put his feelings towards Mitsuki's boy aside to save his life the best he could. "All Might, your quirk is Muscle Enhancement right?"

All Might, not wanting to reveal One for All to her, simply nodded as he watched Rumi thump her right foot on the sand. A clear trigger of her rabbit quirk still expressing her upset nature. She spoke more softly to the two of them, "Very well. Allow me to treat you to some dinner for training my reckless son." Bowing softly as she made her demand to the man. All Might not wanting to be rude simply accepted before texting Hana that he'll be late tonight.

As the night went on, Rumi, Izuku and All Might, in his smaller form, ate a simply dinner for Izuku went to bed. Laughing over the training methods he employed to train her son, Rumi smiled at all might. "You know, I haven't had someone over for a while since Izuku was born. Perhaps we could…" she approached All Might carefully, letting her chest be visible slightly, "Get to know each other better." She licked her lips, her clear pheromones coming off her. All Might simply gulped as he sent Hana another message saying not to wait up for him. All might didn't sleep a wink that night and thanks to the sound proofing in the house, Izuku never knew what he went through.

Month ten came faster than anyone expected. During the last couple months, Rumi Usagiyama had taken a small vacation to help her son with training his legs. She instructed him on how to flick his feet at just the right second to soften each and every jump without losing much momentum. The sight of this set All Might in a state of shock as well as a state of fear towards Rumi after the occasional "training sessions" with her.

As she assisted in her son's training, Rumi began to tell All Might of all Izuku's limitations from being born early. The sorrow of which still wasn't lost on her as she took a portion of her son's potential by being as rash as she was. Additionally she told him of Izuku's fire quirk 'Wisp' and its limited abilities. The prospect of which gave All Might some future ideas for Izuku's training.

Now back in the present, Rumi watched her son from a nearby rooftop as he came closer to the U.A. wall. His ears twitched as he heard someone coming from behind him. Looking, Katsuki Bakugo was approaching the gate as well. The expression on his face was that of 'move aside or get dead'. Out of fear of what punishment his mother might do if they were to fight now, Izuku simply moved to the side to let Katsuki pass. As he went by, Izuku could hear Katsuki say something that made him want to crush all scores now. "Stupid Rabbit."

Deciding on this course of action made instilled a new drive. The excitement of which had Izuku shaking with battle ready hunger. That is until he tripped on his own feet and began falling forwards. Izuku began to prepare to recover using his arms but it never came as he was perpetually hanging in the air. Looking around he could see a brown hair girl smiling at him. "Sorry I know we aren't supposed to use our quirks outside of class but I couldn't let you fall like that."

Looking the girl over Izuku could tell she stood at about five foot six inches. Her face was slightly chubby like mochi, her brown hair matching nicely to her face. Her body on the other hand had Izuku's attention temporarily as she is filled out in the right ways. "N-no problem. I should've paid more attention."

"Well good luck!" With that she ran inside ahead of him.

In the auditorium the students gathered for the live performance of Present Mic, one of the English teachers of U.A. He was doing a DJ bit while the students funneled in. As the doors closed and with a loud voice, Present Mic began, "Welcome to Today's live performance!" Turning around fast with a single finger raised to the sky hollering with enthusiasm, "Let's get a 'Hey!' From everyone!"

Only silence held as he simply coughed to clear up his throat. "Alright then. Well that's cool my examinee listeners! I'm here today to present the guidelines of your practical exams! Hope you're ready!" He echoed hoping that would stir the crowd into a roar.

Silence still remained. After two times failing to excite the already nervous examinees, Present Mic began explaining how the exam worked. Starting with it being monitored by a select group of faculty members for approximately ten minutes. "Each target is worth a point value between one and three that will be printed somewhere on its body! Try defeating any of these three as fast as possible to earn points!"

Izuku noticed a hand shoot up in question as a tall man stood up. "Excuse me, I have a question! How come there are four targets listed? This is a blatant error on the faculties of U.A. if this happens to be true!" Turning to Izuku now, "Also you with the white hair and rabbit ears! Your metal shoes are making too much noise and your hair is disrespectful for being multiple colors! If you are feeling like this is a game leave now."

Clicking his tongue and stopping his bouncing leg that was rattling his backpack, Izuku just stared at the man as Present Mic answered him as examinee 7111. Virtually the fourth target mentioned was like a villain from a popular plumber based game where if defeated it gave zero points. Finishing the 'concert' with a heroism quote from Neapolitan Bonaparte, the examinees left for the buses leading to each test site.

At site Beta, Izuku slipped out of his normal clothing into a leotard, with a belt for his inhaler, his mother prepared for him along with a pair of metal feet that slips over his favorite shoes. After strapping everything down and leaving his bag on the bus, Izuku stretched before the exam started. Examinee 7111 decided to give Izuku another piece of his mind now seeing him in nothing but a leotard. Walking towards him with a bone to pick he was ready to tell him to leave without any remorse.

After a moment of stretching, he went as low as he could into a runner position. As the doors opened, he bolted into the urban terrain. "What are you doing?! There is no starting bell, the test has began! Go! Follow that rabbit boy!" Everyone noticed Present Mic then the open gate before rushing in after Izuku.

Inside Site Beta, Izuku was wearing a large grin as he smashed bot after bot using his ears to locate them as fast as he could. Pulling the inhaler, he took a puff before flicking his feet as he sped off towards his next target only to find examinees taking it down but ignoring an approaching threat. Immediately smashing the looming threat, Izuku sprinted away before they really noticed him.

Elsewhere inside a monitored room, faculty study every single students moves as they fight through the hoards of enemies. A small but commanding mouse-like voice pierced the darkness. "As you can see, We don't tell our examinees how many villains there are roaming the areas or how they are placed. This simulates a large scale battle scenario as villains have become more unpredictable in recent years."

Another voice spoke up next, much more feminine than the mouse-like, "Even now there are those who assess the situation they are in. They use their current knowledge to see what they can accomplish with the limited time given. Some make use of their quirks to search out the enemies." A large whip pointed at a guy with tentacle-like arms, outstretching and searching for bots. "Others use their superior speed to move through the battle field." The whip moved over to a screen with 'Examinee 7111' racing through the course smashing bot after bot that he came across. "And then there are those who use their techniques or powerful quirks to smash through." She pointed at two screens with Izuku and Katsuki as each were handling bots rather differently. Katsuki was destroying bots left and right as he used explosion to accelerate himself to the next location showing how well he was able to move with his current quirk knowledge. Izuku on the other hand was using his rabbit quirk to search for targets, smash them quickly and defend those who were taking on too much despite the protests of many examinees.

Smiling, a paw-like hand reached up and pressed a big red button in front of everyone in the room. "Well, Let's see how they take this challenge shall we?" Back in Battleground Beta, Izuku noticed a large rumbling sound causing him to grab his ears for dampening. The sound was like gears shredding a chalkboard. The ground began to rumble as a shadow loomed now in the sky. Building began to topple as Examinees ran in fear and horror, many of which were screaming about how U.A can do this to their potential students.

Izuku could understand as the sound it was giving off hurt his ears so much that his 'Wisp's began to pop out. Turning to follow suit, he heard something from among the noise. A cry for help. Looking quickly, he could see the girl from before trapped under some rumble, clutching her stomach in agony. She was clearly in the path of the giant machine.

Every reasonable thought was screaming that the teachers would rescue her before any real damages could be done. That the giant zero-point bot would not crush her. She could just use her quirk to get away.

"No..."

Like a bullet fired from a barrel, Izuku began to bounce of each building with all his strength. The fractures of his impacts did little to stop his momentum as he hopped faster and faster. The 'Wisps' of his second quirk blooming as he ignored the burning of his lungs for air as his asthma attacks. "What kind of hero..." He began as he reached the sky above the bot at full speed, "Would leave someone in trouble behind! Rabbit Arts!" Using his momentum, he began spinning at high speed as he descended towards the robot's head. "Obscuro Arc!"

In the control room, the entire room minus one person leaning against the wall watched in awe. They saw a boy, covered in flames rip through the head of the robot destroying it. The people also noted that the girl who was previously trapped, now free and floating on a piece of debris grabbed ahold of him with her quirk causing him to spin a while in zero gravity. That is until they safely reached the ground and she released her quirk as well as her stomach contents.

A/N: Hey everyone sorry for the long wait. Ive been working on this the last couple months. Was gonna add a lot oif fluff but decided not to as its good as is. Hope you guys enjoy. A future note there will be chapters as long as if not longer than this one in the future but not just yet as when I do the USJ, it will be split up into multiple chapters covering each student groups Experiences. Additionally with MHA coming to an end I can make each piece float as best I can. Anyways leave a comment and let me know your thoughts.
