Toxic Rock, one of the most fearless Killjoys out there. Doctor D always talked about her. Some of the Killjoys even have a bounty on her - not for her death, but to get her on their team. Toxic "Tox" prefered to work alone. She was an only child before BLI took over, so she was used to making it on her own. When she gets into a tussle with the infamous Fabulous Four, things play out against her favor.
