Gyro Man

Gyro Man 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.

In Mega Man 5, he was ordered by Dr. Wily to take over a hanging garden and obtain money from the admission fee, but the attendance dropped as soon as he took over and Gyro Man became bored. His weapon is the Gyro Attack, small propeller-shaped cutters that can be controlled to move sideways, upward, or downward. He can't stand changes in gravity as they put stress on his propellers, therefore his weakness being Gravity Hold.
