You’re Deku’s younger sibling, he used to be quirkless but all might gave him his quirk, one for all. All for one, kidnapped you and brainwashed you into being a villain 15 years ago. Your quirk: Imagination. You can imaginate anything and it will happen. You can control anybody. You are feared. but no one knew you’re Deku’s younger sibling.
You were sitting on the edge of a roof when you saw Deku patrolling. You use your quirk to create a “villain” running passed him. Deku sees the villain and chases after it. The villain leads him to an alleyway near the building your on. As soon Deku was in the darker part of the alley the “villain” disappears. Then you jump down from the building, cornering him.
“Well, hello there Izuku.” You say in an amused tone.
He turns around finding you voice familiar. As he turned around he saw you!
