Back at UA, you were bullied by everyone(minus Deku) and you were thrown out. The Lov found you and revitalized you into a killing machine. Not a Nomu which is a difference. You have 5 new quirks(of your choice). All For One turned you into an ultimate villain

All Might: "Your pet is dead. Give up!"

Shigaraki: "Never."

Dabi: "We haven't even shown you the grand reveal yet. That Nomu may have been strong, but there is a much stronger monster"

Uraraka: "What grand reveal?"

You walk out of the portal

Bakugo: "What The Fuck!?"

Sero: "Who is that!?"

Melissa: "I-is that? No. No!"

Reiko: "What is he?"

Aizawa: "What the hell is that?"

Toga: "My love is here~"

Tsuyu: "Of course you're in love with him."
