Chapter 2: Rescue and Reunion

The two strange men wordlessly stepped in front of the group of criminals as the mist, the misty portal disappeared behind them.

"Get them!" One of the younger criminals shouted. A bunch of them charged at the new arrivals, but never got close. A dark cloud burst out of the man covered in it, almost as if his very body consisted of mist. In seconds half of the room was completely filled with darkness that covered the attacking men. A few yelps of surprise and fear were the last signs of the men that had attacked the new duo. As the mist retracted there was nothing left of them, not even bloodstains.

Considering how the duo arrived it had to be some kind of transportation quirk.

The two remaining villains backed closer to Izuku as the misty man approached.

"Kurogiri," the masked man said. "They are mine."

"Yes master."

The misty man stepped aside but even then his yellow glowing eyes seemed to focus on Izuku from behind the mist. The man he called master walked closer. The old man standing above Izuku started shaking.

"Could it be," he said. "All For One?"

"So you know me," the masked man said and chuckled. The sound made Izuku shiver. It wasn't a happy chuckle. The sound promised pain.

"Yes… master," the old man said. "I used to lead one of your enforcer teams in Tokyo until All Might destroyed our operation. Then you disappeared. I… I thought you were dead."

"Many do," the masked man, All For One, answered.

The old man lowered himself to his knee.

"I may not have known of your survival, but I have never forgotten your great gift you gave me. I am at your command if you accept my service again."

"I might have considered that. Your age provides you experience many of my allies lack. However," the masked man looked downwards, at Izuku, "you know too much, and your men attacked my son."

Izuku stared at the man too dizzy and confused to think straight. It took a while before he even understood what word the man had said. The smell of his own vomit was mixed with a new stench as the old man soiled his pants.

"Hey you really know this guy?" The younger man said. He sounded like the one that had talked about shaking Izuku.

The man called All For One raised his hand, his palm toward the old man and a second later a spray of blood rained over Izuku. He felt like vomiting again as the iron scent entered his nose, but he was pulled up as two arms snaked under his armpits and pressed their palms against his chest.

"Don't get any closer or the kid gets it. My vibration quirk can turn his insides into mush before you can stop me." Izuku, realizing the danger, started struggling against the man's hold.

"Let me go," he cried out and raised his tied-up arms, trying to hit his attacker's head behind him. He didn't manage it as the man blocked his hands with one of his own. Even in the haze from all his injuries Izuku was still thinking analytically enough to see the man's mistake. He managed to grab the arm blocking his strike.

The man remembered who he was dealing with. When he realized his mistake, it was already too late. Izuku felt a small shock against his chest, but as the man's quirk left him there was no longer enough power to cause any serious damage.

"No, NO!" The man shouted. Something yanked him back. His arms let go of Izuku but not before they pulled Izuku to fall on his back. He hit his head and before blacking out again barely saw tendrils of black mist flowing around the freshly quirkless man, like dark fingers of death pulling him into a cloud of black as the man's face twisted in horror.

"The blunt force trauma he suffered is not an issue even without quirk-based treatment," someone said in the darkness. He sounded familiar. "The real damage was caused by a quirk, most likely the same one that he took. Creating strong vibrations inside the skull could be the cause of this damage."

"Is it permanent?" Asked a voice that sounded like the man called All For One.

"It could have been, but if you are willing to use your quirks it is not beyond our capabilities to ensure a rapid and complete recovery. He will still need several treatments over a few weeks. I don't have anything against that though. He is the second person ever to manifest the All For One after all."

"You can do what you want to the men Kurogiri sent as long as they never get to talk to anyone again, but Izuku is not for you to experiment on. It would be a nuisance if I had to find people to replace you after all this time."

Someone stepped next to Izuku and touched his forehead. A green glow filled his vision even through his closed eyelids. As soon as it began Izuku's pulsing headache eased up a bit and he sighed in relieve.

"You're awake," the man said. The hand left Izuku's forehead as he opened his eyes.

It was the man with a black helmet, except the top of the helmet was gone revealing… Izuku didn't know if he could even call it a face. The man's bald head was completely scarred and where his eyes should have been, was covered with skin. There wasn't much else to see since his nose and mouth were covered by some kind of breathing mask attached to the lower part of the helmet around his neck.

Izuku didn't dare to move and just stared at the faceless man that had killed a man in front of his eyes. The fact the old man had been the criminal behind his kidnapping didn't erase the blood that had hung around Izuku like fine iron mist.

Still, something in the man, his voice felt… familiar. Izuku's eyes sprung wide open as he remembered what the man had called him earlier. That voice. Now that it wasn't as distorted by the helmet, a little kid inside Izuku recognized that voice even after all the years. It couldn't be. Without even thinking the word escaped his lips.

"D… dad?"

"Yes Izuku."

"It can't be," Izuku said. This had to be some scheme. The man claiming to be his father put his hand in his jacket and pulled out a single photograph. He held it for a moment and handed it to Izuku who recognised his mother in the picture instantly, and also himself as a little kid, and then there was a white-haired man. This was his family. Izuku looked at the faceless man. This was his family too.

"If that is not enough evidence, we also seem to have the same quirk. Your hair even went white like mine when your All For One manifested."

As he spoke the man raised his hand to Izuku, showing a small hole in the middle of his palm. Izuku looked at his own hand which too had had a similar hole since his quirk appeared. The man put his hand back on Izuku's head and the green glow returned.

"All for one?"

"It is the true name of our quirk and the name people know me with."

"I just called it quirk transfer," Izuku muttered. "So, you really are my dad... and you are... are you a villain?"

"Depends on what do you consider a villain."

"You're trying to avoid my question. A villain is a villain," Izuku said.

"I could say the same to you. Villain is a villain? That sounds like something your classmates might say to you. That someone is a villain because they say he is a villain. It is the same with society. If those in charge, if the majority of people would judge you for your quirk or quirklesness, and say you are a villain," he paused, "are you? I know you've been called one."

Izuku stared at him as the words sunk in, bringing up memories of all the times people had called him a villain.

"How do you know?" Was all he could say.

"I've stayed away from you and Inko for obvious reasons," he gestured at his missing face, "to keep you two separate from my… business, but I still kept an eye on you in case something happened. How do you think I knew that you had been kidnapped? Kurogiri, come here."

The black-mist-covered man walked into Izuku's vision. The mist around his head twisted and split, briefly revealing a bit of a human face.

"Kuro-sensei?" Izuku said.

"Yes," his father answered. "He is one of the people that have been keeping an eye on you and Inko for me. Luckily you wore the watch I sent you. It has a tracker in it."

Kurogiri handed Izuku his fancy wristwatch and phone that his kidnappers had taken. Izuku quickly grabbed the watch and held it tightly in front of his teary eyes.

"I didn't have many things from you," Izuku said. "I wanted to hang onto at least that one thing. It felt like someone was there even all the times I was alone. This wasn't what I expected."

"I did not think it would be," All For One said. "To answer your previous question, I am considered a villain of the highest degree. I have sought to change society in many ways over a very long time. With the power of my… our quirk, it was easy to gain support, but that comes with increased opposition. People can worship or fear power depending on how they perceive it. I don't need to tell you how people view our power. In the end those who would oppose me were able to dictate how the society would work with the help of people with powerful and flashy quirks that people saw as heroic. Anyone who opposed them, anyone who even used the quirks they were born with without their permission, was declared a villain. Even anyone associated with a person considered a villain would be ostracised, often just having been born with the wrong quirk is enough for that. That is a large part of why I left you even before my…injuries."

"You… killed that old man," Izuku accused.

"The one whose gang kidnapped and very nearly gave you permanent brain damage? Yes, I did, and he was the lucky one among them. Kurogiri did not give the rest of them the mercy of a quick death."

"They did not deserve one," Kurogiri said. Only now Izuku noticed that his teacher's mist was flowing around him on the bed. Izuku didn't want to ask what they meant, but the misty gesture felt strangely comforting and whatever healing quirk his father was using on him really eased the pain in his head.

"You do not need to accept everything I have done," All For One said. "You may know about me now, but you are also old enough to decide if you still want to have nothing to do with me… after you have properly recovered. We will need to see a few times for your treatments. I can also help you understand your quirk better. No one else in this world can, so you should consider it carefully."

Izuku looked at his hand again. He shouldn't have kept talking with this man. Father or not he admitted to being a villain and had just killed someone, but… Izuku couldn't really deny what the man had said. He felt similarly in many things whether he said it aloud or not. There was also Kuro-sensei, or Kurogiri.

"I don't know much about it. I accidentally took Kach… Bakugo's quirk. I haven't used my quirk since I figured how to give Bakugo his back. I didn't want to steal anyone's quirk."

"Until today," All For One said. "You took a quirk from the man that threatened your life. How do you feel about that?"

"I don't know and… I actually took the quirks from two of them."

"Two in one day," All For One muttered. "I would ask how you feel, but with your other injuries there's no point."

"What do you mean?"

"This is one of the things you need me to teach you. Usually, humans only have a single quirk and for most that is all their body can take. They might survive having a second quirk but there could be side effects depending on the quirks. A few people can have dual quirks or just bodies that are naturally more adaptable. Our quirk itself allows us to amass a large number and our bodies adapt to them, but that will take time. You have gained two new quirks in a single day with no previous training or experience. You may feel some side effects until your body adjusts."

Izuku brushed his chin. If everything going on wasn't so overwhelming, he would have already descended into unending analysis and muttering.

"That makes sense, I guess. I've never actually thought about that. I didn't think I would ever take anyone's quirk again."

"It is what your classmates and society would expect from you. To deny and supress your abilities for no other reason than that they don't like it."

"I often feel like that, but they aren't totally wrong. Stealing people's quirks isn't exactly the right thing to do."

"I sure hope you aren't stupid enough to believe that after today. If you had some flashy super strength quirk you could have punched them to defend yourself. How would that be any better than using your All For One to take their quirks? If you wanted to not injure or kill them that would be even better than many quirks that are considered heroic."

All For One took his hand off Izuku and the green glow disappeared.

"That is all I can do today. You should try to sit up."

All For One stepped further from the bed to give Izuku more space as he sat up. Cables hanging from his head hit his arms and back. The pulsing headache had returned as soon as his father had stopped using his quirk, but the rest of his pains were gone and for the first time Izuku looked around the room. It was dimly lit mostly by a single light by Izuku's bed and a computer screen on the other side of the room. Both were surrounded by medical equipment of all kinds. The room was better equipped than most intensive care units. Besides him, his father and Kurogiri there was one person in the room mostly hidden behind some medical machinery.

"Don't mind the doctor," All For One said. "He doesn't yet wish to show his face to you. Just know you can thank him for treating both of us."

"Umh," Izuku looked towards the hidden man. "Thank you. I feel a lot better."

"Nervous and polite as ever I see," the man responded. Did he too know Izuku? He sounded familiar. "If you can walk straight, you're free to go for today, as far as I am concerned."

Izuku breathed in deep once and got on his feet. Luckily there was no dizziness, just the headache. He looked up at his father's missing face.

"Soo… what now?"

"You will need to come back a couple of times to complete your treatment. After that… As I said, you're old enough to decide. You can continue your life as it is, and I will be 'working abroad' as before," All For One paused, "or if you want to stay in touch and keep training your quirk…s, we can do that, but there are risks and coming back home is no longer an option for me either way."

"I… I'm not sure."

"You don't need to decide today, except on one thing."

"One thing?"

"Your mother."

Izuku's eyes went wide. How late was it? His mother had to be worried sick.

"She figured out I was a villain but does not know even the amount you now know."

"She has always said you work abroad," Izuku said.

"That is the excuse I gave. I don't think she ever truly believed it. She won't be happy about us meeting like this, even less for your kidnapping and injury."

"I am not going to lie to her," Izuku said without hesitation. He looked down at his bloodstained clothes and was grateful he had already emptied his stomach. "Not that I could."

"Very well. I trust you try to keep her quiet about this. Your life will only become harder if people hear you are the son of someone society considers a villain. Holding back Kurogiri might be difficult if that happens."

Izuku glanced at the misty figure.

"Is he going to stay at my school?"

"Yes, and he will bring you here any time you want. You already saw his quirk."

"Some kind of teleportation."

"Warp gate," Kurogiri corrected.

"Are you going to send me home with it?"

"Yes, when you are ready."

Izuku looked at his father.

"I will talk with mom. I have to think about this and I can't decide based on just one side of the story."

All For One's cheeks tensed around his breathing mask as if he was smiling.

"At least she managed to raise an intelligent child. Talk with Kurogiri tomorrow. He will bring you to continue the treatment after school."

Izuku nodded and now a familiar misty warp gate formed next to Kurogiri. Izuku looked at it for a moment, resisting the urge to ask more questions and analyse the quirk. Instead he stepped through without another word. A swirling darkness surrounded him for a moment until the world got less dark and buildings materialized around him. He was standing right next to his house. Looking at the nice two-story building he couldn't help thinking that it was his father, this villain called All For One, that had made sure they could live so comfortably, sending money that he supposedly earned working abroad. Years earlier, finding out that Izuku had a bigger house had irritated Bakugo to no end.

Izuku walked straight through the yard, his mother's pride, and opened the door.

"Yes," he heard his mom talking, "my friend whose son goes to the same school confirmed that he left school normally, but that was hours ago! No, he usually takes a walk after school, but he never goes anywhere for long without letting me…"

Izuku stepped into the living-room where his teary-eyed mother was talking on the phone. She raised her head.

"IZUKU!"
