Her father's the #1 Hero in America. She strives to be like him, she desires to be great like him. The problem is, though, everyone think she has no powers, and he rejects her for it. So she goes against him instead. She becomes the opposite of him, and guess what, she does have powers. They might need a key or something, I dont now. But she uses them for a purpose. Not one her father's going to like.
