I choose is Evelyn from KDA she's good and evil the same time her superpower is her strings in her back which allowed her to trap a person or monster.I invented a cube which only her can touch,the cube is basically contains the story of people lifes,dream and time when she touches the box comes out a gem which is karma do something she will makes you pay it. Evelyn need this cube because the world has so much cruel people sometimes they deserve bad in their live. Finally the cube contained a gem inside (again)
