Mayor Weatherbee governs Newport City during the events of the 1993-1994 OVA series. Her leadership involves managing the city while confronting the Tank Police unit, whose destructive tactics cause significant property damage and expensive insurance claims. To address these issues and broader public safety concerns, she enforces operational restrictions on the Tank Police, reducing their patrols within the city.

Weatherbee shows genuine concern for Newport City's welfare, distinct from predecessors focused on re-election. She actively sponsors legislation banning the private manufacture, sale, and importation of weapons within city limits. This policy directly threatens the primary legal revenue of Dai Nippon Geiken Research Corporation, a major weapons producer. As a result, the corporation targets Weatherbee for assassination to remove opposition.

The weapons ban and her stance against corporate militarization make her a target. Dai Nippon Geiken employs advanced autonomous weapon platforms and terrorist tactics to destabilize her administration. Despite these threats, Weatherbee persists in her commitment to civic safety, leading her to cooperate cautiously with the Tank Police when their protection becomes essential against corporate assassination attempts. During one critical incident, the Tank Police Chief places himself at personal risk beside her as a security measure.

Her governance unfolds against escalating corporate espionage and violence orchestrated by Dai Nippon Geiken. It later emerges that the Rockford Corporation, a foreign entity exploiting diplomatic channels to manipulate arms markets, influences Dai Nippon Geiken. Weatherbee's policies directly challenge this unchecked corporate influence, positioning her as a political obstacle to their ambitions.
