Cook-Cook is a psychotic pyromaniac, expert cook and high-ranking member of the Fiends. He is responsible for preparing meals and serves as a local leader for the gang under Motor-Runner, living in the South Vegas Ruins in 2281.
A minor-leader of the Fiends, Cook-Cook is also known for raping captives, including NCR1st Recon Sniper Corporal Betsy, who still bears the psychological trauma of his attacks, and Pretty Sarah, who was raped, tortured and burned. Additionally, Cook-Cook dabbles in the slave trade; this is notably exuded by Saint James. Once after buying three young girls and a teenage boy, he forced the girls to watch as he set the boy on fire.
Cook-Cook gained his nickname not only because he uses fire based weapons, but also because he is an exceptional cook.
