Kouker Q

Spike Dropper is an enemy in Mega Man 5. It flies slowly across, but the instant you are under it, it folds its propellor, reveals its spikes underneath, and drops like a weight. The Spike Dropper is found only in Gyro Man's stage. The spikes don't kill Mega Man in 1 hit but these nuisances are placed where platforms drop into bottomless pits.
