Kouker Q

Kouker Q (コーカーＱ) is an enemy in Mega Man 5 that was designed after the development of Rembakun. It flies slowly across the screen, but the instant the player is under it, it stalls its engine, folds its propellers, reveals its spikes underneath, and dives like a weight. The spikes won't kill Mega Man in one hit, but they are often placed where platforms drop into bottomless pits. It is found in Gyro Man's stage and the third Proto Man stage.

Other Media
Kouker Qs makes a breif appearance in the first episode of Mega Man:Upon a Star as one of the Wily Bots to create Samurai Man.
