Medical science has made wonders for this world, especially since the dawn of quirks. No longer following a straightforward image of human anatomy, incredible geniuses rose up to take the stand in paving the path for humanity's future. Little did the first generation of quirk users know, the powers passed down by their bloodline would grow more and more powerful. This begs the question, are quirks sustainable in the long term?
The answer to this question was ravenously sought by Dr. Kyudai Garaki. A brilliant mind, although he was reportedly quirkless, he contributed to many things in early quirk science, such as the link between pinky toes and quirk factors and detailing the differences in anatomy between the quirkless and ones with quirks. These were key factors in developing the society that many children and heroes took for granted today. Despite these achievements, Garaki was unwilling to stop his research. The world of academia is a cold, cutthroat world where frequent publications had to be made, otherwise one would perish. Garaki, needing to stay ahead of his academic rivals, knew he had to make a major breakthrough.
Spending years in solitude, Garaki would experiment with the limits of power the human body could take while publishing uninteresting papers on the side to keep his name out there. One day, while compiling his data, the doctor watched the analysis in his darkened, cramped laboratory. Seeing flashes of dark red appear on his computer screen, the doctor dropped his glasses, jaw-dropped.
"What will become of humanity now," the doctor said, moaning in despair. The data he collected was truly flawless this time. Word had to get out immediately before Earth was doomed. In a quick blitz, he compiled what is now known as the Quirk Doomsday Singularity Theory. He immediately signed up for whatever academic conferences he could make a talk in, desperate to share his findings around the world. Seeing a crowd of academics and other professionals, the doctor would begin his talk.
"My friends, thank you all for coming," the doctor said. "I have a most horrific development about the quirk phenomena."
The audience's ears seemed to perk, none of which felt positive.
"As we are in the early generations of quirk usage, the quirks we have are relatively easy to maintain," he would explain. "Although there are many quirks out there with different effects and lifestyle, the act of having a quirk factor has not negatively affected human biology."
A yawn or two could be seen; this was all already well known information.
"However, as you can see from this data, quirks will become increasingly more powerful in future generations," he elaborated. "While at first glance, this sounds positive, the fact is, this is the greatest danger to humanity."
The audience roared with laughter, with some people flashing around their quirks as he spoke.
"Now, l-let me introduce you to the research that brought me here," he said, stuttering. "The Quirk Doomsday Singularity Th-"
Roars of laughter erupted from the crowd, with many comments expressing their disbelief that superpowers can even kill them. This reaction completely drowned out the doctor's presentation, forcing him to end early.
"Uh, t-thank you," he said weakly.
He couldn't even have the face to sit next to anyone at that conference, for this was it. Humanity was truly doomed. He went to the bathroom to wash his face, trying to hold in his tears and mucus in.
"Now, can you tell me more about this 'Quirk Doomsday Singularity Theory?'" a man with a calm voice asked.
The doctor turned around, seeing a very tall, skinny man in a suit approaching him. He had red eyes and white hair, which was a breath of fresh air from the doctor's tired eye, balding look.
"You don't care at all, do you," the doctor said, with destroyed self-esteem. "You're just like those savages."
"I understand your sentiments but believe me, I fully intend to talk to you one on one as gentlemen," the man said. "I myself am also very interested in how the human body reacts as more quirks are added into it. How about we settle this over a nice meal?"
"Uh-" the doctor could barely speak before suddenly being transported to what seemed to be a fancy restaurant. Amazed, the doctor could not describe the power he witnessed in words. "H-how did you-"
"Quite a nice speed quirk, is it not?" the man asked, smiling. "I have other very nice quirks stored in my arsenal if you'd like to see them."
"I- uh," was all the doctor could mutter before taking time to calm down. Once he caught his breath again, he could mutter only one question: "What. Are. You?"
The tall man laughed.
"For such a brilliant doctor, you do ask some silly questions," the man said. "Obviously, no person has been born with more than one quirk yet. So how do you think I have such quirks?"
The doctor did not know how to respond to that question. Quirks are supposed to be unique to each individual, are they not? He only managed some gibberish.
"I should tell you my birth quirk," the man said, laughing. "Quirks can be anything, after all. So why can't they be quirks that allow you to take others' quirks to use for your own or give to others?"
The doctor was absolutely speechless, forgetting his surroundings completely. As thoughts raced his mind, he was approached by a large hand with a hole in the center. Feeling red light flowing from the hand, the doctor felt extremely strange suddenly.
"What did you do with my body?" the doctor asked, feeling completely puzzled.
"Ah, this is a nice quirk you have," the man in front of him said. "A quirk that lets you extend your lifespan by a significant amount, albeit at the cost of physical ability."
"W-What?" the doctor yelped. "B-But I've always been quirkless!"
"That's not what I felt," the man said. "That lifespan extension quirk I just took came from you."
The doctor was shaking in his seat, completely detached from reality. His entire life he was believed to have been quirkless only to learn he actually had such a unique quirk? Now he knew that it wasn't something he just wanted, it was something he NEEDED.
"Give it BACK!" the doctor roared, jumping over the table.
The man did quick maneuvers, easily dodging the doctor's attempt of an attack. Smiling, he put his hand over the doctor's face again, returning the quirk.
"Better?" the man asked. "It's a powerful quirk, one that I could use. I'd be happy to help you duplicate it."
"Why do you want to talk to me?" the doctor asked, still on the floor.
"As a man with many quirks, I have multiple quirk factors," the man explained. "The theory you came up with at the conference was a diamond in the sea of carbon-copy academic research. I believe that together, we can make the world a much better place and stop such a tragedy from happening."
The man extended his hand to the doctor. The doctor looked up in awe.
"W-Who are you?" the doctor asked, slowly grabbing the man's hand.
"I'm _ Shigaraki," the man said. "Or you can call me All For One. The world we seek is right in our fingertips with my powers and your brilliance."
Continuing to slowly grab the hand, the doctor then quickly snatched All For One's hand and got up. Thus, began a duo of a juggernaut of power unrivaled for what they thought would be an eternity.
Now, over a century later, both the men are still at large, hiding in plain sight. It was another day for Garaki in the dark lab, changing All For One's tubes, managing his IV fluids, and giving his master adequate nutrition.
"It's been six years but I still can't believe it," the doctor said. "Even if it's at the hands of All Might, I still can't believe that someone was able to put you in such a state."
"One For All is a finicky thing," All For One explained, this time without the hair or eyes he used to have. Bags of wrinkles replaced the once handsome, charismatic face he had. Tubes connected his neck in a desperate attempt to help the villain sustain basic homeostasis. He was the living impression of a demon lord in the flesh and soul. "It was truly on me all those years ago to let him slip me up like that, especially from the pupil of that Nana Shimura."
"It's a shame that the super generation quirk wasn't as much help as we thought it would be," the doctor lamented. "Your wounds have cauterized so there's not much to heal up there."
"Maybe, but do not fret, doctor," the mastermind said. "Nomu had super regeneration as well, remember? We designed him to be the anti-symbol of peace. And what happened to him after the USJ?"
"Hmm, come to think of it," the doctor wondered, "The news did say some vigilante helped the UA faculty with it. Tomura Shigaraki confirmed this when he reported some strange man who apparently defeated Nomu with ease."
"Yes," All For One answered. "I know exactly who it is now."
"Who?" the doctor inquired, curious as to who the mystery man could be.
"The answer is both in plain sight and also not," All For One explained. "There was a man with spiky hair and dark clothes by the name of Goku, correct? He stopped the Looney and Clooney duo."
"Yes but what's a band of ragtag thieves compared to people such as you?" asked the doctor.
"It is not the power of the thieves here, but what the powers of Goku are," the mastermind replied. "From that report, we know that Goku has superhuman physical strength as well as an energy blast ability. During the bout with Gigantomachia, you informed me that he received bruises from punches. And against Nomu? We were informed that Nomu was outclassed in physical strength completely as well as being finished off with a powerful beam. To make matters even more curious, there are zero records pertaining to Goku at all. It almost feels as if he is not of this world, don't you think?"
"Do you seriously believe that?" the doctor asked incredulously.
"It wouldn't be out of the realm of possibility," All For One replied. "Despite the public's perception of the fight, at most, we would have had only a small margin of error with Nomu if put against All Might. Worst case scenario for us, All Might would have defeated Nomu with great difficulty, disabling him for the rest of the day. As much as I hate that smiling buffoon, the power he wields is second to none. However, Goku was able to completely flatten our plans with no difficulty. You would find that a little suspicious, don't you think?"
"So is there a plan for you to retrieve his quirk?" the doctor asked, understanding this 'Goku' person a bit better now.
"As of now, unfortunately, no," All For One replied. "However, I would like to give him a little 'test.' All Might in his prime probably would have demolished Nomu in five strong blows; the peak of One For All we all hate to remember. If Goku passes this, I'd happily bump him to the top of the priority list for quirks to take. I have a batch of quirks for you to work with, see if you can make anything with this."
The villains smiled, excited for their plans to regain the dominance over global affairs they once had.
On a more well-known side of Japan, Goku Black was using his laptop, getting much more accustomed to the technology of the mortals. Once believing it to be a burden, he now felt it to be an incredibly useful tool that completely changed his lifestyle. Able to find books, entertainment, and education with the internet, Black felt more in awe of how mortals were able to web together such an extensive network of resources. He clicked around until he saw 'Amozan,' a site for online shopping.
He fell into a deep hole of things he can buy from the comfort of his own home. To think that the mortals were capable of such automation! Black was left in disbelief, as he once tried to exterminate all of them.
Mortalkind was not what I thought it to be, Black thought. But Project Zero Mortals is still on the backburner as a contingency plan.
Finding a nice looking book, Black read the preview and decided to try to buy it. Upon clicking the purchase button, he realized that he had none of these 'credit cards' humans had.
Damn it, all my money is physical, Black thought, frustrated at how he did not see this coming. Reaching out for his phone, he texted the group chat with the Hottas and Kamayan.
Goku: How do I get a credit card?
Jiro Hotta: Don't you have a bank account?
Goku: A what?
Ichiro Hotta: Where the heck have you been keeping your money then?
Goku: Why does it concern you?
Ichiro Hotta: Ok, fair question, but most people keep at least some of their savings in a bank account. You've gotta have a plan with that!
Kamayan: How the hell have you gone so long on Earth like this?
Ichiro Hotta: Whatever, just bring your ID and things over to us tomorrow morning and we'll set you straight with it.
Goku: I don't have these things, I have no documents for my identity. I just never did the process.
Kamayan: How the hell have you been employed for so long?
Jiro Hotta; I mean, we're not ones to talk as we're villains. Alright, we're going to the social security office to straighten all of this out as soon as possible. Meet us in the cafe tomorrow at 6 AM sharp, Goku. These offices are very weird about policy.
Goku: Understood, thank you for your time and have a good night.
With that chaotic conversation out of the way, Black took yet another night of sleep, this time, sleeping better than he ever had in this universe.
The next day, Goku and Jiro Hotta were taking the bus on their way to the nearest social security office.
"They open at around 8 AM," Jiro said. "But it usually takes two hours to get there so when we get there, it'll be right on time. They're real suckers for 'first come first serve.'"
Black nodded, although he was feeling increasingly annoyed at the slow trip.
"Couldn't I have just flown us there?" Black asked. "It would be much faster and we would've gotten more sleep."
"This is off of work so we can't justify it as being on the job," Jiro said. "You'd actually get into hot water. Also, I'm not fond of such heights."
Black rolled his eyes and groaned, having to accept this sluggish ride. At 7:55 AM, they finally arrived at the office, where there was already a small line starting to form.
"Go, go!" Jiro hollered at Black, who was confused about the hurry.
The Saiyan and the grasshopper-in-disguise only needed to wait for eight minutes before finally being allowed to enter the premises. Clearing a security check, the duo checked into a kiosk, for Black to apply for social security of his own.
"And now we wait." Jiro instructed.
Seven minutes later, it was Black and Jiro's turn. The receptionist was a lobster woman who seemed annoyed she had to take the morning shift.
"How may I help you," the receptionist asked, not even hiding her annoyance.
"Hi, I would like to help him apply for a new social security number," Jiro said, in reference to Black.
"Fill out this form," the woman said.
"I haven't got the slightest clue as to how I should answer these," Black said, looking at the pages of government jargon he couldn't wrap his mind around despite having read much more advanced literature.
The woman sighed, frustrated at the idiocy in front of her.
"What is your immigration status?"
"I-I don't think I've ever decided that," Black said.
"So you came here illegally?" the woman asked, feeling very suspicious.
"I-uh I-"
Before Black could come up with a reason, suddenly, a fearsome gray creature crashed into the building, attacking the guards who managed to throw it off of the visitors. Suddenly, a huge pack of these creatures bursted through the walls, with one even bursting from the lobster receptionist's back, dragging her away from the premises, much to her horror.
"Damn it, of all times!" Jiro exclaimed. "I'll go after the one who took the lady. You probably got the rest, right?"
Black smiled, the same one he used to make at the sight of ruins he used to create in Trunks's timeline.
"This will actually be quite a delicious morsel," Black said, cracking his knuckles.
Getting into his fighting stance, he was able to decapitate one of the creatures in one slice. Noticing the increasing horde of them, Black flew towards them, listening to his body's desires. Needing battle to sustain his lifestyle, the wrath of rage, hatred, and anger would be unleashed to the public eye once more.
Author's Note: So there's chapter 11! A long one! I feel like I might have made the government a bit too Americanized but I searched up Japanese Social Security and it seems like that's actually the thing it's called. No idea how it works but I'm kinda too lazy to find out.
