Melissa worked as a research and development assistant for BAHRAM's Orbital Frame Project, supporting Dr. Rachel Links in developing the advanced mecha prototype Idolo.

Secretly, she operated as a covert agent for the United Nations Space Force (UNSF), gathering and leaking confidential Orbital Frame technology and progress data.

During a UNSF infiltration of a BAHRAM testing facility, Melissa participated directly, seizing Dr. Links and Dolores Hayes as hostages. She facilitated their removal from containment to extract Orbital Frame research for Earth's military forces.

While escorting the hostages on an escape vessel, Melissa intercepted an escape attempt by Dolores and Dr. Links. She confronted them and fatally shot Dolores. This act triggered an extreme psychological reaction in Dolores's lover, Radium Lavans, piloting the Idolo nearby. Radium's loss of control caused the Idolo to crash catastrophically. The crashing Orbital Frame impaled Melissa, causing her immediate death.

Melissa's narrative presence is confined to *Zone of the Enders: 2167 Idolo*. No verified information exists regarding her appearance or involvement in other franchise media.
