Cyborg Q appears in Himitsu Sentai Gorenger as a spy serving under the Black Cross Army general Iron Man Mask Temujin. Her background is that of an artificial being constructed to resemble a normal human woman named Aya Mizuki, whose identity she assumes as a cover. In terms of personality, Cyborg Q is deceptive by nature, using her appearance to infiltrate and gather intelligence on the Gorengers. Her primary motivation is to serve the goals of the Black Cross Army, though her story arc takes a notable turn.

Within the narrative, her role is that of an enemy operative sent to spy on the heroes. She is discovered by Kirenger, the Yellow Ranger, who finds her after she jumps from a cliff and nearly drowns in the ocean. Kirenger saves her life, bringing her to shore, unaware that she is a cyborg agent working for their enemies. This event establishes a key relationship between Cyborg Q and Kirenger, as her deception directly involves him. Her development is significant, as she is recognized as the very first villain in the Super Sentai series who experiences a change of heart and becomes an ally of the hero team, even in death. Regarding her abilities, Cyborg Q wields a dagger as her primary weapon but can also extend sharp, metal fingernails to use in combat. Her end comes at the hands of a fellow Black Cross operative, as she is ultimately destroyed by Warship Mask.
