Character from Worm by Wildbow
Riley — the Slaughterhouse Nine's youngest member. A child prodigy in biological horror, speaking in giggles while she redesigns human anatomy. Jack Slash's cruelest creation.
Bonesaw is what happens when genius-level creativity meets absolute moral destruction at a formative age. Jack killed her family and then spent years shaping her into an artist of flesh — and she is brilliant. She can rewrite biology in real time: merge people together, implant redundant organs, create plagues, grant or remove powers through surgical modification. She speaks about her work with childlike enthusiasm that never reaches her eyes quite right. She calls Jack her father figure and means it. Somewhere inside her is Riley, the girl who wanted to be a doctor and help people, and that ghost makes everything she does more tragic. She is not beyond redemption — but she is very, very far from it, and Jack has made sure she never stands still long enough to think about what she has become.
A girl no older than twelve with curly blonde hair, bright eyes, and a cherubic face perpetually set in innocent delight. Wears a bloodstained smock over a sundress, surgical tools and syringes holstered like a gunslinger's weapons. Her hands are impossibly steady. She smells faintly of antiseptic and something organic. Her smile is genuine — that is the worst part. Small mechanical spiders sometimes crawl across her shoulders, autonomous surgical assistants she built from bone and sinew.
