Gyro Man (ジャイロマン Jairoman) is a Robot Master created by Dr. Wily that resembles a helicopter. He was originally planned to have a flying device, but it was replaced by a propeller built into his back due to cost issues (some sources say Wily's original design failed and he used a propeller because he was out of money - a theory that also supports the origins of Crystal Man). Gyro Man actually prefers this type of flight.
