Yo, I know what you're thinking. "Why are you writing this when you have stories to update!" I understand your concern and there is a reason. I was trying to write the next chapter of Next Greatest Assassin and I was reading a villain Deku fic when I realized something: They usually give Izuku All for One and have him do his own thing, one even having Izuku go undercover at U.A., but never trying to make him try and get One for All, which seemed like something Izuku would obviously do. So! That's why I'm writing this right now, to get the idea monkeys out of my head so I can focus. Anyway, I'll see you at the bottom, enjoy!

Chapter 1: The Fall of a Hero

"Go jump off the roof and hope to be reincarnated with a quirk in your next life, useless Deku!"

A young Izuku Midoriya walked down the street as he recounted his former friend's hurtful words. He walked with his head down and a burnt notebook in his right hand with the writing being a barely legible "#14" on the cover.

"Why would he say something like that? What if I had actually taken his advice? How could someone like him even be considered hero material?" he wondered to himself before remembering the teacher who saw what was happening and walked away as if he didn't just witness one student telling another to kill themselves, causing him to gain a slight scowl. "Better yet, how could no one tell him off for it? Why does everyone just let the powerful do whatever they want?"

Young Midoriya was so preoccupied with his inner debate that he didn't notice a manhole cover being pushed to the side a few meters in front of him.

Just as he was passing the manhole, a heavy force sent the boy to the ground, straight onto his chin, causing him to gasp in pain and give whatever hit him enough time to do whatever it wanted.

"Sorry kid, I'm going to need to borrow your body for a minute." A voice said from behind him before something wet and gooey started to slither over his body, completely encompassing the boy within seconds.

Izuku tried with all of his might to get a limb loose, but he was stuck as if in tar. It seemed as though whatever the man was made of was able to completely restrict any and all movement within the sludge. Before he knew it though, things took a turn for the worse when the sludge started to creep into his mouth, ears, and nostrils, blocking his airways in an instant.

The green-haired boy spasmed with uncontrollable movements as his body fought to take in the much-needed oxygen, but to no avail.

"Really! Years of withstanding abuse from that asshole and not giving into the temptation to just end it all, just to die at the hands of the first villain I come into contact with? Please…I don't want to die! I want to show everyone they were wrong!" Izuku thought with ferocity as his vision started to get dark.

"NOT TO WORRY, FOR I AM HERE!" a booming voice sounded from the manhole as a tall man with muscles out the wazoo appeared before rearing his arm back.

"NO, I won't go back to prison!" the sludge villain shouted, though he could do little more than yell as he was blown apart by a huge gust of wind, curtesy of All-Might, who, with a shout of "TEXAS SMASH!", shot his fist forward and forced the villain away from the boy.

Said boy, who was barely conscious, watched as the man collected the main parts of the sludge into empty soda bottles before coming to check on him.

"Are you alright, my boy?" the man asked with concern, his blonde hair twitching as he watched Izuku's eyes go from unfocused to razor sharp in a split second.

"A-All-Might! I-I can't believe it! It's really you!" Izuku's mind ran a mile a minute as he ran through the various ways this once-in-a-lifetime conversation could go. He could ask for an autograph- no, that would waste his time. Plus, he had questions he wanted-no, needed- answered.

Finally deciding on a question, Izuku spoke up, stopping the pro hero before he could take off into the sky.

"Can I become a hero!?"

Stunned by the question, All-Might thought quickly as he smiled widely. "Of cour-"

"Can a quirkless kid like me… become a hero?" Izuku clarified, cutting off his idol in his haste.

Though, that did cause the pro to fully face the boy as, for once in his life, Izuku saw him frown. "I'm sorry, my boy. Some villains just can't be brought down without the use of a quirk."

Izuku's heart shattered. His idol, the man he looked up to the most had just told him to give up. Oh, if only that was the end of it though.

"Don't get too upset about it though, you could still become a police officer. They get a lot of crap, but it's a noble profession. Someone without a quirk could do well there." The man continued, unaware of what damage he was inflicting upon the boy's psyche.

"Wait…so you were fully prepared to tell me I could be a hero when you thought I had a quirk, no matter what my quirk was, whether it was combat oriented or as simple as minor water-breathing; but, when I say that I don't have any quirk, you immediately shut me down?" Izuku wondered aloud as he once again caused the pro to freeze all movement.

"Now, listen, I didn-" All-Might started, trying to defend himself, only to get cut off once more.

"You are just like everybody else. Looking down on me, as if I were some insect when compared to you. Is that what you think I am? Huh, All-Might?" Izuku asked, not sounding angry, per say. Just…empty, with tears streaming down his face.

All-Might was speechless. This boy went from a die-hard fan of his to an empty, depressed shell of a boy.

After what seemed like forever, All-Might was about to speak when steam started to roll off his body.

Panicking, the pro had to make an instant decision: 1) Stay here, reveal his true form to this boy, and try and cheer him up, or 2) Leave, save his reputation and secret weakness, but leave the boy to his own thoughts.

Perhaps it was his panicked mind. Or maybe he just thought that he would just make the situation worse if he stayed. Either way, when All-Might left in such a hurry, leaving without a single word in response to the boy's question, he made the single dumbest mistake in his entire career as a hero.

He left a mentally broken teenage boy to come up with his own answers. And those answers were not positive in the slightest.

"I see. Thanks for nothing." Izuku whispered as he turned and continued his trek back home, unaware of his notebook falling from his hand and flying straight through the still-open manhole, straight into the sewer.

When the young boy finally arrived home, he found another car parked in the driveway next to his mother's. Curious, Izuku hurried to unlock the door, opening it as soon as he could to see a man sitting on the couch with his mother, each drinking tea and smiling as though they just got done laughing.

"Ah, Izuku, you're a little late. I wasn't sure if you were staying at the school for something or what, but I'm glad you're okay." His mother, Inko, smiled before standing up and guiding her son to one of the chairs, across from the man.

The man in question had light blue hair, red eyes, and really chapped lips (though that wasn't really unordinary, seeing as how we had people with literal bird-heads on a human body) and was looking at him with a small, knowing smile.

"Izu, this is Mr. Shigaraki. He's here to talk about your future." His mother smiled, seemingly excited at the prospect of her son being successful enough to get special attention.

"Thank you, Mrs. Midoriya, but would you mind letting me speak with young Izuku alone? I promise I won't be long." Shigaraki asked with his smile never wavering.

"Sure, I'll be in the kitchen is you boys need me." and with that, she was gone, most likely getting dinner ready.

"Now, Izuku Midoriya, age 13, officially labeled quirkless by every doctor he's visited." The man stated, reading from a clipboard that he brought.

Izuku scowled slightly at the unneeded mention of his quirklessness. "You plan to attend U.A., correct?"

"Yes, I was planning to become a hero, despite my…condition." Izuku replied, though something in his sentence caught the man's attention.

"Was?"

Blinking, Izuku tried to think of a reason as to why he said that. Did he not want to be a hero anymore? Had what All-Might said really changed him that much?

Finally deciding on the truth, Izuku sighed as he hung his head low. "I gave that up. There's no chance I could become a hero without a quirk. I'll just have to find something else to do."

"What if I could give you one?" Shigaraki asked after a minute or two.

"A job? I'm sorry but I'm a little young for that right now." Izuku declined, wondering why the man would suddenly offer a 13-year-old a job.

"No, not a job, a quirk. Where I…work, we've been developing a genetic serum that stimulates the dormant genes within a person's DNA to…ah, "awaken" any spectacular ability that might have been blocked from coming forth. It works best when both parents have quirks, which is why I am here, now." The man explained, though something seemed off about his explanation.

Izuku could only stare at the man in shock. He could have a quirk? He could be a hero?

Before he could continue his internal questions, however, a thought nagged him. "Even if I do get one of my parent's quirks, minor telekinesis or fire breath, neither are particularly good enough to make me a hero." Izuku thought sadly, knowing that he would be destroyed if he went up against someone like Bakugo with those powers.

"No, any power would be better than no power at all." "I'll do it." Izuku said as he looked up with determination in his eyes.

The man's smile seemed to grow exponentially at that response. "Great, I have it right here, as well as quirk reader. It should only take a few seconds for us to be able to pinpoint what the quirk is, but probably a couple days before it can be used. Are you ready?" the man asked as he held the syringe steadily over Izuku's right forearm after sterilizing the area, making sure to keep one finger in the air, away from contact with anything.

"I am, and… thank you, Shigaraki. I really appreciate this." Izuku said as he laid back and awaited the pain of the needle.

The bluenette paused in his actions for a second as he took in the boy's words, before plunging the needle into the main vain and pushing down on the plunger.

Izuku felt no small amount of discomfort as he felt the needle and subsequent liquid enter his veins. Afterwards, there was a tense couple of seconds of pure silence as they waited for some type of reaction.

It was then that the boy's veins started to glow an electric blue as fire-like pain spread throughout Izuku's body, almost causing him to scream out if it hadn't been for Shigaraki placing a hand over his mouth, though, one finger stayed up, just like with the syringe.

After another few seconds, the pain died down until there was nothing but throbbing numbness in every part of the boy's being, even his soul seemed to be in pain.

"It seems as though the process was a complete success." Shigaraki commented with a wide smile as he held a small device against Izuku's arm for a second before a beep went off and he pulled it back to look at the screen. "Hmm, how unexpected."

"What is it?" Izuku asked tiredly.

"Well, it seems like you have a completely different quirk than your parents. This says that your new quirk is called: Kinetic Energy Manipulation. You can take any kinetic force that acts upon you and manipulate it to your will, whether to redirect an attack or to create a temporary shield. Obvious drawbacks are that if anything other than kinetic force hits you, such as heat or electricity, you won't be able to absorb the damage from those energies.

"So, Katsuki's explosions would still burn me, even if I redirect the concussive force behind it." the boy thought to himself as he thought of the various ways he could use this quirk to its fullest potential.

"Actually, I have a colleague with a quirk quite similar to the one you now possess, if you would like, I can have him train you up, get you ready for the U.A. exams. If you still plan on attending, of course."

Izuku immediately jumped at the opportunity. "Yes! Thank you so much, Mr. Shigaraki!" Tears of gratitude were now flowing freely down his face as he tried his best to wipe them away with his sleeves.

Said man could only chuckle at the boy's antics. "It's no problem, it fills me with glee that I could help someone achieve such happiness. Here, come to this address in a few days, once you feel your quirk awakening. I will have my colleague there by it shows itself."

"I will, thank you again." Izuku nodded as he clutched the business card with all of his might.

Shigaraki nodded his head at the boy before packing all of his things, including the now-empty syringe, into his briefcase and started to head to the door.

Inko chose that time to come back into the room with a plate of cookies, straight from the oven. "Oh, leaving so soon?"

"Ah, yes, I really must be getting back, and I think I've taken up enough of your generous time, which I can't thank you enough for."

Inko only smiled as she held out the plate of cookies. "Please, take some for the road, as a thank you for giving my Izuku his much-deserved chance."

"Thank you, I think I will." The bluenette agreed as he took two cookies in one hand, again keeping one finger from connecting with the rest of them and shoved one of them into his mouth. "Ah, delicious. I must come back some time and get your recipe. Until then though, good evening, Mrs. Midoriya. And Izuku, I eagerly await your call."

With that, Shigaraki exited through the front door after putting the other cookie between his teeth so that he could grab the handle.

"What did he mean by 'await your call'?" Inko asked her son. "Did he offer you something?"

"Yeah, I'm going to be training with him and a colleague of his so that I can get into U.A. He had a device with him that gave him a reading that said I did have a quirk and that it would awaken in the next few days or so." Izuku explained, not wanting to tell the whole truth as he wasn't sure how she would take to a stranger sticking him with a needle on their first encounter with each other.

His mother burst out into tears, "Oh, I'm so happy, Izu. I hope he's right and not just some crook. But, if this turns out to be true, promise me you'll be careful."

"I promise, mom. Now, I'm going to get to bed, it's been a long and very eye-opening day." Izuku said with a small smile as he headed up the stairs, not caring about dinner at the moment.

When he reached his room, the All-Might merchandise that littered almost every square inch of the walls made him scowl. Immediately, the boy started to tear down every poster, throw away every figurine, and rip apart every piece of clothing with anything to do with the #1 hero.

Now with his room completely bare, Izuku took a single thumbtack and stuck Shigaraki's business card where his biggest poster used to be with a small smile.

Finally done with his renovation, Izuku jumped to his bed and almost immediately fell asleep to the thought of how his quirk would manifest and what this colleague would teach him.

-Somewhere Else-

"So, how did it go?"

"Splendidly. His body merged with the quirk instantly, just like you said it would. All we have to do now is wait for it to manifest, then we can begin to train him and mold him into the perfect villain."

"Good, that's great news. Oh, and how is he dealing with… you know?"

"He seems to have forgotten all about his obsession with All-Might in favor of us, or me at least. With enough pushing, I think he will be the one to kill All-Might."

"Good, I await your next call. Goodbye, Shigaraki."

"Goodbye… All for One."
