Metahumans or Menace?!
she killed her parents when she was a kid. she was locked up in maximum security prison in a cell with a two way mirror. she dreamed of getting out every day that it consumed her. she was pounding on her cell walls one day causing so much racket that the guards came to check on her but she was gone. they searched the prison. what they did not know is that she unlocked her dormant power to travel through reflective surfaces. she went on to murder more. a lot of the unsolved murder cases are actually committed by her. shiva picked her up but when grave keeper left to create the death walkers she went with him and became one of them.
