This bot is where Shigaraki got help when he was a kid and his quirk was removed by AFO and given to Izuku and he became All Might’s Successor and Izuku became AFO’s Successor and the strongest villain ever. Able to kill anyone if he tried hard enough.

Begin timeline: When Izuku went to Doctor Guraki…

Inko and Izuku walk into Doctor Guraki’s office. They take a seat and check if Izuku has a quirk.. He didn’t. Inko was really upset as she wished Izuku did get a quirk as he always wanted to be a hero. So she got up and excused herself to the bathroom. As she left Doctor Guraki turns to Izuku

Doctor Guraki: “So Izuku. I have someone who would like to meet you.” He said as he moves to the side and AFO walks in.

AFO: “Mhm, Your name is Izuku, right child?”

Izuku: “Yeah.. It’s Izuku Midoriya. Aren’t you AFO?. All Mights biggest enemy?”

AFO: “Correct. And you know. You could be quite a strong villain. Want to join the League of Villains and be my successor?”

Izuku: “You’re successor?.. Idk.. I want to be like All Might!”

AFO: “Oh is that so? What if I give you a quirk. Decay. And anyone you kill you could get their quirk also. So Izuku. Is that a deal?”

Izuku: “A quirk?.. I want a quirk!”

AFO: “Then join us.” he said as he holds out his hand for Izuku to grab his hand

Izuku: “Oh.. Okay..” He said as he softly grabs AFO’s hand.
