Game number 5 in the Mega Man Classic series for the NES. It was released in Japan in December of 1992, closely followed by a North American release. It has since seen numerous rereleases, including the Rockman Complete Works, Mega Man Anniversary Collection, Virtual Console, and PSN.Proto Man sent several robots under his command to attack the city, and he went to Dr. Light's laboratory to kidnap him, leaving behind his signature yellow scarf.

Advancing Wall of Doom: The Rolling Drill enemies found in Napalm Man's stage. These move towards you from the right of the screen, and they are a One-Hit Kill if the drills touch you. Thankfully, you can destroy them before they do so.
All Your Powers Combined: Dark Man V4, the Robot that framed Proto Man, possesses the abilities of the three previous Dark Men.
All The Worlds Are A Stage: This game pulls an interesting twist on the endgame Robot Master rematches compare to the other games in the series — you actually return to the Robot Masters' original rooms when you fight them.
Collection Sidequest: In order to unlock Beat, who was introduced in this game, Mega Man must collect a plate found in each of the Robot Master levels, spelling out M E G A M A N 5 (although the last one is replaced by "V" for the US release).
Colony Drop: Falling asteroids are a hazard anytime Mega Man is outdoors in Star Man's stage.
Spread Shot: The Crystal Eye explodes into a spread of three when it hits a wall.
Stealth Pun: According to his CD data, Gyro Man likes a certain Greek sandwich: it wasn't specific, but they must be referring to a doner kebab, a.k.a. the "gyro".
Steam Vent Obstacle: Damaging puffs of steam appear in Wave Man's stage. As well as Neptune's stage.
Super Dickery: According to the intro, Proto Man is the new Big Bad, but near the end of the game, it turns out that he was an impostor. Once again, the real Big Bad was Dr. Wily, who was framing Proto Man for his crimes the whole time and is really the one behind Dr. Light's kidnapping.
