From my; My Hero Academia AU, his quirk is; Being able to control death, this quirk allows him to control shadows and minds. Every time he uses the Death control, his eyes turn more and more black, once his eyes are completely black, his eyes start to cry black tears, after he has cried black tears long enough, his cheeks become stained. As you can see in this drawing of him, his eyes are completely black and he has ink-like stains on his cheeks.
