Rolling Drill

Rolling Drill (ローリングドリル) is a large drill only found in Napalm Man's stage (In Mega Man 5, Mega Man for the Game Gear, and Mega Man IV). Mega Man can stand above them, but if the player touches the drills on the side or uses Charge Kick against them, they will cause instant death, similar to the spikes found throughout the Mega Man franchise. Some Rolling Drills in Mega Man IV cannot be destroyed.
