Isabelle Cronkite is an investigative reporter relentlessly pursuing the truth behind Dancouga Nova's operations and origins. She repeatedly investigates the mysterious super robot despite explicit warnings to cease and significant personal danger encountered during her inquiries.

She develops a theory that Dancouga Nova's interventions—consistently aiding the losing side to restore balance—intentionally perpetuate continuous warfare by preventing decisive victories, creating deliberate stalemates across global battlefields. This analysis is later validated when the International Alliance reveals its motivations: deploying Dancouga Nova to maintain controlled, ongoing skirmishes and prevent full-scale world war.

During a fact-finding mission, pilot Sakuya Kamon rescues her from jeopardy, catalyzing the development of personal feelings toward him and shifting her personal interactions.

As the story progresses, deeper insight into the true nature of the conflicts and the robot's purpose transitions her role from adversarial investigator to Dancouga Nova supporter, aligning her with the team and their objectives. Her name serves as an homage to a reporter character in the anime series Sengoku Majin Goshugun, another Ashi Productions creation.
