Dr. Retentive was the head of NEOCORTEX. She was activated in "Trojan KORPS" and seen in "One Flew Over the Budgie's Cage". Her KORPS division was concerned with biological research. She is sent to a nightmare treatment centre and installs a new form of "treatment", happy chairs. The happy chairs take away all the secrets from M.I.9 agents who come here. Frank London nearly has his secrets taken away by the machine, but his M.I.9 bravery medal saves him and Dr. Retentive is arrested.
