One year later, Midoriya Residence

Inko shuffled about the apartment, cleaning up and arranging all the odds and ends of the place. As she passed by the photo of her and Izuku, she paused and held it in her hand.

"Izuku... come home."

League of Villains Lair, Deku Age 8

Deku slammed into the wall and slumped to the ground. A ring of scorch marks decorated a dummy in front of him.

"You didn't brace yourself again." Kurogiri helped Deku off the ground. "It's not just fire, but a-"

"Concussive force that follows after. I know, you've told me a million times." Deku snapped at him, annoyed to no end.

"Then why do you keep forgetting? You know you'll only be sent out for missions when you master it, so why do you keep failing?"

"You try having another person in your head yelling at you all the time."Stop, let me out, please stop!" It's irritating." Deku punched the dummy, sending a spark of flames out and cracking the fabric face.

"Perhaps you should inform master if Izuku is becoming a problem."

"No, it's fine. He's annoying, not overwhelming." Deku walked back a bit and readied himself, letting loose a burst of fire and holding his ground when the shock wave came after. The sound of clapping brought him out of his moment and he turned to see All for One at the entrance with Tomura.

"Impressive. You've progressed quite well this past year, my boy. A bit more training and you may very well be capable of destroying All Might." All for One patted Deku on the shoulder.

"Thank you, master, but we all know you'll do that."

"You can't kill him! You won't win!" Deku held his head as the voice of Izuku ran louder in his head. All for One put his hands behind his back.

"He's still troubling you?" At this, Deku simply stood taller and shook his head.

"He's louder sometimes, but I've got him under control. All he can do is scream." At this, All for One chuckled and placed his hand on Deku's shoulder.

"Excellent. Remember, you are my student, not Izuku. Izuku was weak, but you are powerful, Deku."

"Thank you, master." Deku bowed slightly and smiled brightly.

"That's my boy. In any case, it's time you resumed your studies. Your mind is important, and we don't want it going to waste. Kurogiri, if you would." The misty villain stepped forward and the pair left the training area.

"Master, do you prefer Deku over me?" Tomura asked, looking down at the ground. "He's always doing more than I am, and he's even going to be going out on missions before I will-"

"Tomura, listen." All for One knelt down on the pavement floor to look the boy in the eye. "Deku is important, but you are my successor. He will find the information and things needed to help create my plans, but you will be the one to carry them out and see them work. Deku learns what he does to better blend in, be hidden in plain sight. He is my hidden dagger, while you will be the hand that wields it. You understand?"

"Kind of." Tomura fumbled with his sleeve, and All for One chuckled.

"Deku is useful as a spy, but you will be the leader of the League when the time is right. For now, you require more training." At this, All for One sent a bunch of red spikes into the training dummy which stood on its feet as one of his stolen quirks worked it like a puppet.

"Now, Tomura, remember what I taught you. Attack." At this, Tomura lunged at the dummy, which then began to dodge and weave out of the way of the boy.

One Year Later, League of Villains Lair, Deku Age 9

Deku was currently sparring with a new member who possessed a quirk that let him jump high and fast. Tomura was currently fighting with a group of motorized dummies. Both of them were winning. Deku blasted a confined stream of fire at his opponent and the man went flying to the roof when the shock wave hit him. Deku's sparring partner slammed to the pavement and slightly curled up from the pain.

"Damn, kid. You've got some kick to your quirk." The man smiled, and Deku returned the gesture, his red eyes sparkling.

"You're not bad either. You almost had me for a moment. Hey Tomura, you done?" Deku called out as Tomura finished off the last dummy.

"Yeah, I'm good. You think master's back?"

"We can go ask Kurogiri." At this, Tomura groaned.

"Hope he doesn't make us do more chores. He always makes me sweep everything." Tomura slumped slightly and walked with Deku to the lair's lounge area. There, they bumped into Kurogiri, who took them by the shoulders.

"Get whatever personal things you have. We're relocating." At this, the two noticed the rest of the compound seeming to be getting mounds of stuff in boxes and crates and heading to the main garage.

"Kuro, what's going on?" Deku asked, looking up at his misty mentor.

"All Might. He found our master, wounded him, and now we need to go to him. I've sent All for One to a secure area, but we need to evacuate." At this, the pair just stood in stunned silence. All for One, the Symbol of Evil, their mentor, their father figure had been beaten? Kurogiri lead the both of them down the hall to the hanger sized garage, and opened a warp for the equipment and personnel. He then shouted out a bunch of orders to the League's members, who all went off in different directions.

"Kuro... where is master?" Deku asked, trembling with fear.

"... Follow me. But I warn you both, it's not going to be pretty." Kurogiri lead them down a steel hallway to a medium room. Inside was a cluster of medical equipment and machines. Lying in the bed of this amalgamation was All for One. His face was scarred and his throat had several tubes and wires coming out of it. The two boys slowly approached the man and faced him on either side of the bed.

"... my boys. You're here. Good, good." He held up a weak hand, pointing at Kurogiri. "Kuro, my gifts to the boys, get them please." At this, Kurogiri turned and walked out the door. Deku approached and put his hand over All for One's.

"Master, are you gonna die?"

"No, my boy. All Might wounded me, but my quirks and some doctors will see that I survive. Now my boys, come closer." Tomura and Deku got to the edge of the bed, and All for One put a hand on both of them.

"You two are brothers in our mission, and as such both of you will lead the League to glory one day. I have suffered, yes, but All Might has suffered more. Both he and I managed to gravely wound each other. While I will recover, he will slowly lose what strength he has left. That is where you two come in." At this, Kurogiri returned with a wooden box. Opening it, he held out a dagger to Deku.

"Deku, you are my hidden blade. You will blend in with those who would see us ruined, and when the time comes, deliver a brutal blow." Deku took the knife, and Kurogiri held out a pale hand with a socket type attachment on the end to Tomura.

"Tomura, you are my hand. You will carry the league when I can not. You will be the master of them all, my successor. Both of you, once All Might is dead by my hand and the symbol of peace is broken, you will lead the league to greater heights. To create the age of villains."

Deku gripped the knife tight and raised it up. "The age of villains!" He shouted while holding back tears.

Tomura placed the hand over his face to conceal his sorrow. "The age of villains!" He shouted out as well.

"That's my boys. Now, go with Kuro. I need to rest and heal." The boys both bowed and walked out. As Kurogiri walked ahead, Deku held his forearm out to Tomura.

"Brothers." he stated, and Tomura put his forearm up to form an X.

"Brothers. Forever."

Inside of Deku's mind, Izuku Midoriya was crying out, shouting at the darkness around him.

"You won't kill All Might! I'll stop you! You hear me? I"ll stop you!
