Dr. Mogg is Nora Wakeman's biggest rival in robotics. Mogg built Y-K 9 "Kenny" to oppose X-J 9 "Jenny". Mogg boasts that Kenny is better than Jenny as he can hear and smell better than Jenny. When Nora confronts Mogg about coping Jenny, she smirks when Kenny back talks Mogg and Nora says "Not so easy is it," refering to how diffcult "raising" a teenage robot can be. Dr. Mogg forbade Kenny to see Jenny and Kenny informed him that he (Mogg) needs to stay out of his (Kenny) personal biuness.
