The minute Izuku tried his best to activate One For All, his body felt like he was hit by a freight train, his muscles felt like they were being torn to shreds, and he had a tough time standing up straight if not breathing normally when he tried to calm down and take a deep breath he immediately began to get this terrible coughing fits, and as he was coughing he felt like something was wrong with his body, his ability did a lot to help to keep repairing his body, but it continued to be injured almost from the inside like One For All was trying to kill him, as he walked over to All Might who had this looked of utter shock on his face, he began to cough up blood and collapsed in a heap on the ground, unconscious.

Toshinori never heard of this ever happening to any of the previous people who inherited One For All, but that was not the most important issue, he needed to get his successor some medical attention, but he couldn't go to a normal hospital should knowledge of One For All be released to the general public, the chaos and potential threats by other villains wanting to get their hands on it, by any means was simply too high, but he couldn't simply leave Izuku to die to keep the secret.

That is when he remembered that he had one choice, he quickly took his watch and pressed a hidden button that activated an SOS signal to a very skilled doctor that was in charge of treating everyone at UA, not wanting to waste a second he immediately picked up Izuku in his arms and began to run towards UA, he didn't care who saw him or that he used the limited time he had in this form, but he had to make sure Izuku, his successor lived, or else he too would not be able to live with the guilt that he caused the death of his successor, such a noble and kind-hearted kid. He rescued the person who had been essentially his childhood bully, even while many would have stood by and let their bully simply die, to get rid of that headache. Not Izuku, as long as he knew that person was innocent, he jumped in trying to save the person, regardless of how dangerous this was to himself, he placed the safety of others before even thinking of his own.

Toshinori couldn't help but smile in his mind thinking that he may call himself a pirate but when it comes to saving innocent people, he was more of a knight in shining armor than even he was, and people recognize him as the Symbol of Peace, the top hero, that was almost ironic and he thought this as he finally made it to the grounds of UA, where recovery girl, Nezu, and other heroes had been waiting for him with a medical gurney, "That isn't for me, it's for this guy, he suddenly collapsed, looks like he is in immense pain, and started to cough up blood as I did, I could have had him be treated by Max and his wife, but in a panic this is the only place I could think I could trust, please Recovery Girl, please I beg you, save the life of my successor, the guilt of causing his death is something that I could not bear."

The lady walked up to him and immediately asked him what was his blood type, Toshinori told him he had no clue until he noticed his wallet and a medical bracelet, and he immediately told her it was a universal donor, Type O. She quickly looked at the two other heroes and told him to prepare the clinic, and somehow get some bags of O type blood from the local blood bank, they don't have enough at present in the clinic. "Damn it, we usually have some, but we end up going through it rather quickly since we use it to treat most students, and we haven't restocked that in some time, get Midnight and tell her we need for her to use her quirk to put the kid asleep, as long as he is awake, his body react to anyone present and cause himself even more harm, what the hell are you looking at, get moving, we don't have time to stand around like this. MOVE IT."

Midnight's side kick Mightnight understood immediately what Recovery Girl was thinking, she removed Midnight's jacket and Midnight used her quirk to act as a form of anesthesia, helping Izuku to fall into a peaceful sleep, hopefully, this would relax him enough for his body to calm down and they can figure out what the hell is wrong with him. As he was on the examination bed, she had to complain about if she was a lot younger, or if Izuku was closer to her age, she might want to ask the guy out, he looked so cute sleeping like that. She quickly stopped those thoughts as she remembered that this guy might be a future student, and this was not appropriate for a teacher to think of a potential student.

Izuku found himself in a rather large space, a large group of men dressed as pirates were fighting what seems to be seven glowing balls of light, and they didn't look like they were holding back at all, he only knew that after they attacked each other and after each hit, he could feel as if he was the one getting hit instead, "Damn it, must be inside my mental scape, and these are the things causing me to feel like I do, I got to stop this or else, these idiots are going to end up killing me, a pirate to die on dry land, I don't think I could survive such a shame to my pirate pride."

He walked up and began to imagine that they were standing on the deck of his dream ship, his version of the Vengeance, the surrounding quickly changed and they stopped fighting as they were shocked by the sudden change in the area, Izuku walked between the two groups and glared at them both, "Now listen here, you miserable blichrats, you are on my bloody ship, so get that wax out of your ears, and for once in your miserable lives, listen, you need to fucking stop all this fucking roughhousing, cause you morons are going to end up killing me, and I don't know about you, but if you idiots do that, I will drag you lot with to aboard the flying dutchman when it comes for me, so unless you don't want to do that, we are going to go by pirate code, and parley! You understand me, or do I need to fire my cannons at your empty coconut heads to make you listen?"

Several of the pirates came to help Izuku stand as he was still feeling the pain from the last few punches two particular idiots had done against each other as he said that. "Aye, aye, Captain, your ship, your bloody rules, we will not attack this lot of land lovers if they promise to keep their groovie hands to themselves. You made me quite proud hearing you talk with such authority, I knew that my son would make a magnificent Dread Pirate Roberts." Hisashi was very proud of how his son dealt with the situation and was impressed he realized where he was so quickly since he was able to change how his mindscape looked so quickly.

"Now hear this, I don't want to hear excuses, lies, or other crappy justification, I want bloody facts, and I shall have that and only that, now who cares to answer me this, why are you bloody lot fighting like this inside my mind, nearly killing me? And don't tell me one side started it, 'cause you ain't teenagers, your bloody adults, act like it." Hearing what he said they quickly began to turn into more human-looking people and they walked over to him, "I am sorry, we are the vestiges of the previous torch holders of One For All, I came and many of my fellow heroes thought this place was invaded by villains, we thought that by defeating them we could help save you. We meant you no harm, we honestly thought that we were trying to rescue you from the clutches of such evil and vile men."

One of the pirates was furious upon hearing what this man said and walked over to Izuku, "You bloody dare call us evil, we are the vestiges of the previous Dread Pirate Roberts, we ain't evil or vile, we have saved more people and done more heroics that you stupid lot even know off, we were the first real heroes, not like you miserable lot who does good deed only to win fame and glory, I would say you lot are two-faced opportunist, and you dare say such things about us!"

Izuku looked at the man with a cold glare and he understood he would not stand for either of them fighting, "You have a child understanding of the nature of what pirates are, yes, many were evil, rotten, and cruel, but not all, like not all so-called heroes are virtuous and selfless individuals, stop trying to pain everything with such wide strokes, and listen, pirates and pro-heroes first and foremost they are people, evil can exist in both. So stop fighting or so help me, I will grab this coin and summon Davey Jones and he can drag all of us to a watery grave, you get me?"

One of the vestiges still wanted to kill the villainous pirates and refused to listen, so Izuku took his silver coin in hand and looked at them, "The King and his men took the queen from her bed and bound her in her bones, the seas be ours and by the powers were we will well go." Upon hearing those words every single vestige of the Dread Pirate Roberts stopped immediately and they knew he was not kidding at all. One of them screamed at the foolish professional hero vestige and told him to stop or else they will get dragged down to a place that makes hell look like a paradise. The hero noticed that the pirate was not kidding from the sheer look of terror in his eyes. This single act had made a bloody pirate this scared, it was clearly not something to take lightly.

"Fine, take away my fun why don't you, alright I will play nice with the pirates, but why are you someone who has One For All, being so nice to these no good high seas bandits, these pillaging menaces, these mass murdering menaces?" Izuku looked at the tall man who looked like he spent years working out, and looked like he shaved his hair off, and simply told him because he might have One For All, but he was still a pirate, and damn proud of it, causing the other vestiges of the Dread Pirate Roberts to shout a cheer.

"Now there is one person I know who would not let any of your horses around like this, she would have slammed her foot down and made you lot behave even if she had to force discipline down your bloody throats. I know you are here, so no point in hiding, come on out granny, I know you are here, mind telling me why you didn't step in and discipline this bunch?" A young woman appeared from behind several other vestiges, apparently, they thought they needed to shield her from the pirates, stupid doesn't begin to describe it. "Sorry Izuku, it took me a while to enter your mindscape after I felt something was wrong with you, the other surviving vestiges are coming soon, so don't worry, Naruto and Sasuke will keep the pirates in check, and you know Sasuke doesn't take kindly to brats. Now come here and let me give you a hug, at least here I can hug you without thinking you would cause me to break a rib or a bone."

One of the vestiges still wanted to keep her away from him as he was dressed as the other pirates, till he punched him in the gut and told him she never needed anyone to defend her, not then and certainly not now, as one of the other vestiges asked her, who was the kid? She rushed and hugged him and with a smile, she told the others, this was her grandson Izuku Midoriya, grandson of Steven Midoriya, and son of Hisashi Midoriya, as she pointed at two of the pirates who were smiling at her. "They are no danger to me, in fact by the looks of it we are more of a danger to Izuku, so unless you want All For One to win, and One For All to be destroyed, stop fighting as my grandson told me, for if this happens those that don't listen are official minions of All For One, is that what you want?" They finally realized how foolish they had been, acting on pure impulse, and adrenaline, they understood they were acting no better than a bunch of teenagers looking for an adventure.

"Look all of you have to live inside my mind, and if this keeps up and you keep fighting there will be no more Dread Pirate Roberts or One For All because you lot will cause my death helping All For One achieve his lifelong wish of eliminating the ability that he lives in fear of, so either get along or accept the fact and title of being All For One minion, your choice, I don't need to mention how many of you he has killed do I?" This finally made them realize that their actions were helping the one thing they shared in common, their utter hatred of a common enemy, they both agreed to not only accept each other but try to find ways to cooperate and boost their abilities by working together, thus the ability of that he got from his father and One For All will end up becoming even stronger.

As he finally opened his eyes, he realized that he actually somehow managed to knock out quite a few of Plasma's clones and even several of the instructors, it seems that at one point when he was no longer under the effect of Midnight's quirk, he would beat up and even knock out anyone that tried to restrain him, Vlad had to be treated by Recovery girl several times, but he had to agree for a person so young he had one hell of a right hook.

Nezu on the other hand found this to be quite amusing, he even went as far as to say he expected no less from his protege, this made every person present cringe as they heard Nezu laughing in a way that they wondered if he was actually a villain whose whole plot was to educate heroes to eliminate potential competition. This however doesn't explain how fast he can go into overprotective papa bear mode the minute that the lives or safety of his students is threatened. The thing that surprised them was that Izuku was this strong and he was capable to knock out professional heroes and he was only attacking as a reaction to other people.

It was by the next morning that Izuku finally woke up, and somehow his body began to heal a lot faster than Recovery Girl was expecting, somehow his body seemed to have a healing factor that started to repair his body down to the cellular level, and the only thing that kept him unconscious was that every bit of energy his body could produce was focused solely on healing, to some it was quite frightening, and to Recovery Girl it was amazing, she had never seen someone recover from such extensive damage to their muscles and sensitive parts of their body this quickly and this efficiently.

He woke up in the bed of the Academy clinic, somehow thanks to him spending so much time talking to these vestiges in his mind, he found so much information about the abilities of the previous Dread Pirates, and he also learned quite a bit about training and controlling One For All, from the previous people that once had the quirk. Nana was the most willing to share the difficulties she once had and how much trouble her master Grand Torino had in helping her train to use the quirk. The first user of One For All told him an absolute tear-jerker story about how his brother forced a quirk down his throat without realizing that he already had a quirk, as such he had plenty of things to talk about with these people, which means he was not surprised to see how long he was asleep.

"Well that was a productive night's sleep, boy, I can't believe the shit I just went through, and why is everyone looking at me like that? I hope I didn't do something bad when I was unconscious." All Might did say that he did actually punch and kicked a few of the staff a few times, and he did cause a little bit of trouble for the UA Clinic since they had to get some blood to replenish the blood he coughed up, so they had quite a bit of work to keep him alive. Izuku apologized for causing all this problem, but he did manage to do something rather incredible, this made Nezu and the others wonder what does he mean by that.

"Inside my body, the vestiges of the previous people who had One For All were fighting against the previous people who were the Dread Pirate Roberts, the battle between these vestiges was actually the thing that was causing me physical and mental harm, only when I was completely unconscious was I able to enter my mindscape and managed to meet with all the vestiges, so I finally got to get them to stop fighting and get along thanks to the help of granny Nana, well that was strange and I learned a lot about One For All."

All Might has to ask what he means by the vestiges, Izuku told him that it was mental copies of the previous people who had once Once For All, and the previous Dread Pirate Roberts, and they were amazed to hear about Nana and the other previous holders of One For All and apparently taught him many things, the thing that was amazing to the others was to learn that before the tenth person to inherit the title of Dread Pirate Roberts quirks did not exist at all, but after the tenth Dread Pirate Roberts quirks began to appear, and every single Dread Pirate Roberts after the tenth once developed quirks which would later be inherited along with the title to each of the successive people that inherit the title. He can only tap into the powers of the first nine abilities of the first nine people to inherit the title of the Dread Pirate Roberts.

Izuku told them that as far as the vestiges told him his quirk and ability are influencing each other to such an extent that they are merging together for an entirely different and quite possibly new quirk, a quirk that is made up of both parts, and since this is such an extensive change, and it is happening throughout his body, they told him that using extensive amounts of his power before his body can adjust and the quirk finished its evolution and finally settles down, would be potentially fatal, so they advised him several times that at best, he can use sixteen percent of his total power in case of emergencies, but that will cause severe pain, trauma and possibly injuries, so they told Izuku it would be best if he used as little as possible of his quirk and they also told him that it might even get stronger over time.

Izuku, however, did tell them that he had access to every ability that the first nine Dread Pirate Robertson once used, and that at least means he could take down villains which means he could probably take down some unruly, unscrupulous scoundrels, and with enough support gear and gadgets he could take down at least up to Class A professional villains, "They want me to go to UA, study, train, and get along with people, but we all know I can't stay sitting with my thumb up my ass if I see a person's life in danger, I can't help it. So chances are I will end up making some stupid decisions, taking some rather foolish risks, and trying to save innocent people while in immense pain, while wearing a stupid grin on my face, because I don't want to cause people to worry or feel anxious, cause when people panic it tends to make the entire thing of trying to save them extra difficult."

Nezu asked him what could they do to help him, Izuku mentioned this as a sort of a joke and said if they could get Erasurehead to teach him his style of fighting, that would be a lot of help, since like he said until the quirk finished changing and settled down, he can't technically use it, "The only upside is that All Might is cured of his injury, so technically he is no longer suffering from that and is no longer under that time limit on how long he can use One For All, I do think we need to keep pretending that he is injured and much weaker or this might cause All For One to do something absolutely nuts out of sheer desperation. He once used the quirk to take on that muscular form to hide his weaken form, well now he has to do the opposite, use his quirk to appear weaker, to hide the fact that he has recovered."

All Might pretty much told Izuku he essentially was as weakened as he once was after he received his injuries that took one of his lungs and his stomach, to which Izuku told him essentially that was true, except that unlike him he was not missing two large organs, his body was undergoing too many rapid changes and in such a critical and fundamental way, that his quirk essentially was in a state of flux, constantly changing, and this was putting a massive strain on his entire body. "Like I said I will be pretty much like one of the first nine people that ever inherited the title of Dread Pirate Roberts, at least till my quirk finished changing and becomes stable, when that happens I will have to meet with the vestiges again to find out exactly what One For All ended up becoming, and then they will teach me how to best train and get used to it, and only then will I ever be able to use more than sixteen percent of my power."

Vlad asked him what if he had to face a world-ending threat, a villain that makes All For One look like a schoolyard bully by comparison, Izuku told him in that case since if he doesn't stop the threat of that villain, the world is pretty much screwed, so technically he would have no alternative but to do something stupid, and use one hundred percent of his power, and if he did that, he could stop that villain, as long as others don't mind the fact that he more than likely will drop dead the second after he did that.

"So in that dire situation, I am forced to quote a very wise man said in an old movie, the needs of the many outweigh the needs of the few, or the one, in such a world-ending scenario, saving the lives of an entire world, at the cost of one life, most people would call that a bargain for the ages. Personally I rather not fucking die like that, I want to fall in love, marry, have kids, and eventually have grandkids whom I can spoil, but that is neither here nor there, because, in the end, we simply don't know how our lives will go or how we will end up, and we don't always get what we want, now do we?"

Izuku told them that in the end he can only do his best, and have to accept that, he simply said he was at best a young adult, but after all the memories, experience, and knowledge that will come with all those changes I will go through, I honestly wonder if at the end, will I still be me? or will I end up becoming someone new?"

Someone just asked him if this isn't scary to him? He might never be the person he once was, "It can be if you focus only on how it affects you, but like I said the needs of the many, outweigh the needs of the few or the one. At this moment in time, I have the knowledge, memories, and wisdom that make me thousands of years old, yet, I am not at the same time, here is what I came up with, this idea, why do people become heroes? For glory, fame, attention? You are not a hero, you are a glory-seeking jackass, you only care about yourself, and only yourself, a hero does not become a hero for his own benefit, but for the benefit of others, they get to live the happiness of a problem-free ordinary life, but the hero has to live second by second in a constant struggle against those that would harm others and against himself not letting the power they hold make them into a villain. That is why I say I may do heroic things, but at the end of the day, I am the Dread Pirate Roberts, and I am alright with that."

As Izuku said this, Nana, Naruto, and Sasuke arrived walking through the door into the UA Clinic, nobody was expecting them and Toshinori was happy to see Nana but then asked them what took them so long to get there, Sasuke looked at Toshinori with a scowl, "Look brat, we got the feeling someone was wrong just half an hour ago, and we were across the world, so excuse us if it took us a little time to fly here, we also contacted the other surviving Dread Pirates so they could connect to the ability, and help the kid out, so mind telling us what the hell have you lot been doing till now?"
