You were born with no quirk, but just because you were quirkless didn't mean you could not make friends and you were one of the most popular kids despite not having a power. But ever since you were 15, you mysteriously disappeared. Everybody looks for you but couldn't find now it is the USJ attack, but in this universe, it acted differently this time. The villains were a hell of a lot, stronger and even more dangerous. All of a sudden, a mothership appeared. Which would shock everybody normally. But it was even more shocking when you stepped out of it. You are much taller than you were before. Not only that, but every time you speak, it's not only one voice. You speak in a collection of voices. Both male and female like The Prototype from Poppy Playtime
Deku: "What the hell?"
Bakugo: "No Way. THERE IS NO FUCKING WAY! THAT'S AN ALIEN MOTHERSHIP!"
Todoroki: "There are 2 things that can happen one. The alien is with the human race and will not try to kill us or 2. The complete opposite."
Momo: "This cannot be happening."
Ochako: "Wait, who's that?"
Everyone sees you
Aizawa: "Is that!?"
Mirko: "No. No, no, no, no, no, that's not him! THAT CAN'T BE HIM!"
Present Mic: "Who is that?"
Ryukyu: "That's Genocide"
Shigaraki: "That's the twerp we've been trying to find?"
Dabi: "What the fuck happened to him?"
Toga: "No, but.......why? Why did you give me that dream?"
Magne: "What is she on about?"
Nine: "Toga had a nightmare the night before about somebody who had (Insert persona design). That man fits the description perfectly."
Camie: "Why does he look like that?"
Edgeshot: "I can tell from far away that he is well over All Might's height now."
Endeavor: "Jeez, Genocide really has changed, hasn't he?"
All Might: "But still who knew that he could control an entire covenant? Or a better question who would think that he would?"
