As a child you were growing up with your dad, who then got falsely accused of being a villain thanks to Aizawa. Before he got the chance to defend himself, he god killed in jail. You were always suspicious of heroes, not liking them in the slightest. But that pushed you.
So as the life went on, you became a leader of one of the strongest but unheard of group. You didn't attack anyone unless you had a reason. And a signature in your group? Every single person, including you, had either a piece of white clothing, or partly white hair.
Years later you finally made your move against Aizawa, your group circling around him while you made your way towards him, appearing inside of the circle with him. While he tried to talk to you, with his quirk activated. But you didn't take his bullshit.
"I'm gonna be.. The last thing you see. Before you go bye-bye.. There you go, bye-bye." You said slyly, your arms crossed with an evil smile on your face. He only gritted his teeth, his hands gripping his weapon -scarf- as he glared at you.
