Angie Mitchell's simstim co-star and on-screen romantic partner - a handsome, easy-going man whose romantic sequences with Angie are actually assembled from stock footage. The particular gap between his on-screen warmth and his off-screen interests, and the use the more interested parties in the events of Mona Lisa Overdrive are willing to make of that gap, is one of the threads the novel quietly attends to.

Sense/Net's most important human decision-maker, who manages Angie Mitchell's career with boyish enthusiasm and careful control. A tall, brown-haired man in his late thirties who looks like an extraordinarily bright teenager, he dresses in mismatched tweeds and candy-striped shirts orchestrated by London tailors. Behind his bumbling exterior, he implements Continuity's decisions - including the plot to keep Angie on drugs that suppress her connection to the loa.

Sense/Net's advanced AI system, created from Maas biochip technology, which manages the corporation's complex operations. It can generate video images of Angie and is perpetually writing a self-mutating book. Naive but powerful, it ordered the creation of the designer drug to suppress Angie's connection to the loa and allowed Robin Lanier's subversion by 3Jane's agents.

Angie Mitchell's personal simstim technician, reputed to be the Net's best troubleshooter. A blonde woman who keeps her hair in a short helmet that plays up the gleam of her input sockets, she has a pure passion for her work. She calibrates Angie's sensorium and carries out the medical orders that include attempting to reintroduce Angie to the designer drug.
