She is the daughter of Yeva who inherited her AbsoluteSolverinfection and witnessed both her parents be murdered by Serial Designation V as a child. Growing up, Doll became remarkably skilled in controlling her Solver powers, all while killing and devouring fellow Worker Drones for survival. Bent on eliminating V as retribution for her parents' deaths, she had her best friend Lizzy lure her target into a trap at the school prom of 3071, though Doll's attempt failed as she was defeated by Uzi, Serial Designation N and V herself. Later on, Doll continued stalking her enemies then formed a temporary alliance with Tessa Elliott, until she stole the Keybug for herself and fled to Cabin Fever Labs. There, she orchestrated an ambush on Uzi's allies and tried leaving them for dead to the Anti-Drone Sentinels.
