Biography
Kess was a violent and a mad cold blooded killer who detested the Ood. Kess was charged with capturing the Ood who had the red eye virus and was also charged with capturing the Doctor and Donna Noble. Kess attempted to kill the Doctor using a piece of machinery but was stopped by Solana Mercurio. Klineman Halpen had Kess try to gas the infected livestock which Kess took great pleasure trying to do, however other squads of Ood broke into the container room, freed the Ood he was trying to gas, removed Kess' gas mask, and locked him in one of the cages as the gas went off. He was then gassed. (DW: Planet of the Ood)
