The Fall of a Hero and Rise of a Demon (Gyutaro!Izuku)

The Big Boss

3rd POV

Shigaraki led Gyutaro deeper into the base, before finally coming to another room. Inside it was a lab with many tubes that were filled with strange creatures. "These are our secret weapons Player 2," Shigaraki explained, "they're called Nomu, and they will help us destroy this society, so we can build it back up." Gyutaro walked up to one of them, inspecting it, "Man, I didn't think there was anything else in the world that could be uglier than me," he commented. Shigaraki snickered a bit, before he was interrupted by a new voice, "Well, to be fair, they're not exactly alive, so I'd say that you're still the ugliest thing alive." They both turn to see an old man with no hair, goggles, and a lab coat sitting towards them. "Wait, I remember you," Gyutaro said, "you're Dr. Tsubasa, you were the one to diagnose me quirkless."

"Ah yes, young Midoriya, I recognized you the moment you two arrived. I see you eventually did get a quirk, and powerful one at that,"the doctor praised. Gyutaro smirked in gratitude, before looking at another tank that made him do a double take. "Wait a minute," he started, "isn't this your grandson? These are his wings, right?" The doctor got up from his chair and walked over to stand next to the demon, "You are correct young man, this use to be my grandson" he grinned wickedly, "I never really cared for the boy to be honest. The only thing I cared about was his quirk, since flying quirks are so rare you see." Gyutaro glared at the creature inside, "Doesn't matter to me, he's better off being used for something useful rather than being another waste of space." This caused the doctor to laugh, "Hohohohoho! I am so very glad you agreed to be with us young man. Also, call me Garaki dear boy, Tsubasa was merely a fake name. If you need anything at all just come to me, although I would love to study your quirk in exchange, if we have a deal that is."

Gyutaro grinned, agreeing to the mad doctor's terms. He waved goodbye and returned to Shigaraki, who was waiting for him while he was on his phone. They both returned to the bar and ordered drinks from Kurogiri, with Shigaraki getting a Mountain Dew and Gyutaro having sake. "So, what do you think of our weapons," Shigaraki asked while sipping his soda. "I think we have a chance of defeating him, especially if we target his weak spot," Gyutaro replied as he almost finishes his drink. Shigaraki stopped drinking for a moment, before asking, "Wait, he has a weak spot?" Gyutaro grinned, "Sorry, I thought you already knew. But yes, he has a huge scar on his side that never healed from an intense battle that he had a few years ago. He foolishly told me this after I saw his true form." Shigaraki matched his grin, "So what you're saying is that this will be even easier. And if all else fails, you just need a little swipe from one of your sickles in order to poison someone."

We clinked our drinks together, and drank the rest of it. All of a sudden, the TV turns on, once again displaying 'sound only,' "I see you were able to successfully recruit the Demon Tomura. Well done." Sensei praised. Tomura smirked, glad that he made his Sensei proud. Meanwhile, Gyutaro was curious of who this person was. "Tomura, Kurogiri, would you two mind if I were to talk to our new recruit alone?" Sensei asked. The two in question nodded, and went out of the room. The TV suddenly showed picture. It was of a man hooked up to multiple tubes, but the most obvious feature from him was that the upper half of his face was covered in scar tissue, with not even his eyes being present. It slightly unnerved the demon, but shook it off as the person on the TV began to speak, "So you're the Demon everyone has been talking about. I must admit, you're younger than I thought you'd be," the man said.

"Well, I'm glad I exceeded your expectations. My name's Gyutaro by the way. Who are you anyway?" The demon asked.  "It's good to make your acquaintance Gyutaro. You may call me Sensei. I am the leader of the League, and Tomura is my ward," Sensei replied. "Well, your ward and I have the same goals, so I look forward to working with you," Gyutaro smiled. "I must ask child, what is your quirk? In all my years of living, I've never seen such a diverse quirk such as yours," Sensei questioned. Gyutaro looked at his hand, before clenching it, "To be honest, I don't even know how it works. When I dived off that roof, I could feel all my sadness and anger at once. When I lived, it must've manifested itself as my quirk. It was like my own willpower gave me the power to crush those who have wronged me," he answered.

"Thank you for answering young Gyutaro. I know you will be a great companion towards my ward. As for the plan, we will need you to infiltrate UA when the new year begins and bring the schedule back here. Can you do that for us?" Gyutaro bowed, "Yes Sensei. I will not fail you. I will prove my worth." Sensei chuckled, saying, "Thank you Gyutaro. Now run along, I'm sure Tomura would love to show you some of his games." Gyutaro nodded, and exited the room while the monitor turned off.

In an undisclosed location, Sensei, aka All For One, grinned. 'The pieces are being set. Soon, All Might will perish, and Gyutaro will learn who his successor is, which will only continue to fuel his hate for the world. This will be the turning point, and things will soon change in our favor,' AFO thought as he started to chuckle, before once again start to view his progress once again.
