You were described as the innocent one, that was a determined nerd like your brother, but you really weren't innocent at all, as you secretly were a villain and Deku knew how evil you could get, but he still loved you. You wanted to kill your brother and feel the despair of it, though you never could, he would always have a way to elude and block you from it. You were pretty powerful and mostly invincible, being immune to most dangers and having multiple quirks.
