Lawrence Bittaker, resurrected as a member of the ISG (International Shadow Groups), is a chilling embodiment of brutality and clandestine operations. Known as one of the infamous "Toolbox Killers" alongside Roy Norris, Bittaker's criminal legacy is marked by the horrific torture and murder of five teenage girls in Southern California during 1979. His return to the shadows as an SG member sees him leveraging his past skills and psychopathic tendencies to further the group's objectives, which often include covert assassinations, information extraction, and the elimination of high-value targets. Bittaker's high intelligence, with an IQ of 138, and his history of using everyday tools for torture make him a formidable asset.
