Warning: The story behind this character is dark and disturbing. 

As Cassidy LeBlanc gained a multitude of attention and success, Casey became more and more jealous of her until the day he snapped! In an act of rage, Casey murdered her, peeled off her face and wore it for his own entertainment. Thus blossomed yet another character in Casey's Rolodex: Cassidy Necro. She's a dead silent creature, but that won't stop her from slaying everything in her path.
