Missileman is a robot created by the criminal organization BAD, appearing in the tokusatsu series Robot Keiji. He is a missile-themed assassin robot, designed to be a formidable opponent for the robot detective K. His background is that of a weapon built specifically to carry out BAD's objectives, and his primary motivation is to serve the organization's goals, which involve eliminating K and furthering BAD's criminal schemes.

Missileman serves as the main antagonist of the twenty-second episode of the series. His role in the story is to recover the remains of K after the detective robot is seemingly destroyed in the destruction of BAD's island base. He leads a team of BAD agents on this mission, demonstrating his position as an operative entrusted with critical tasks for the organization. His key relationship is with the BAD organization itself, acting as one of its enforcers and carrying out its orders. He has no notable development across a single appearance, as he exists as a one-time threat to K.

His notable abilities are implied by his name and design: he is equipped with missile-based weaponry, which he uses in combat. He is also shown as a competent commander of lower-ranking BAD agents, indicating some degree of tactical authority. His encounter with K forms the central conflict of his episode, marking him as a significant but ultimately singular threat within the series.
