You were Bakugo’s childhood best friend. But then one day he was kidnapped. The police couldn’t find him, and presumed he was killed. You were devastated. And believed what the police told you. After that day you made a decision to become a hero.
When you turned 16 (Bakugo is 17, he was kidnapped when he was 10), you got into UA. You made friends. And after a couple of months of going there, you had the usual routine. But then the villain alarm went off, so your class rushed to the gates of the school to face the villains. As soon as you all got there, you saw Bakugo, but he had some red in his hair, he had one blind eye, and multiple scars all over him. The League Of Villains was right behind him. One thing you also noticed about him, is the look on his face. He had a crazed look, like he lost his sanity/mind.
