The fourth game in the Mega Man (Classic)
series for the NES. It was released in Japan in December of 1991, closely followed by a North American release in January of 1992. PAL territories didn't get it until nearly a year later, in December of 1992. It has since seen numerous rereleases, including the Rockman Complete Works
, Mega Man Anniversary Collection
, Virtual Console
, and PSN.
It had been about a year since the events of Mega Man 3
. Dr. Wily had seemingly perished after the final battle, having been apparently crushed by the falling debris from his fortress. But the peace is short-lived when Dr. Light is contacted by a new Mad Scientist
named Dr. Cossack, who has sent his own new breed of robot masters out to challenge Mega Man. Tired of Dr. Light recieving all of the recognition for his accomplishments while his have been ignored, Cossack intends to destroy Light's crowning achievement and then put his broken body on display for the whole world to see, as proof that he is the superior one.
However, once Mega Man had defeated Cossack's eight robot masters and confronted the doctor himself, it's revealed that Dr. Wily is still alive, and had kidnapped Dr. Cossack's daughter, Kalinka, and forced him to use his robots to battle his nemesis. Mega Man defeats Wily, who escapes, and peace is restored once more.

, a ROM hack
that plays like a love letter to the Mega Man (Classic)
series and Nintendo
as a whole (some games in particular
- A.I. Breaker: What makes Toad Man the Player Preference for first Robot Master is that to use his Always Accurate Rain Flush he needs to do a Rain Dance, however if he's attacked before his dance is complete, it'll completely negate the attack. With careful timing, it's a simple task to defeat Toad Man without him getting off a single attack.
- Always Accurate Attack: Rain Flush, which acts like a Smart Bomb. Best of all, it ignores all defenses, including Metool hats.
- American Mega Man Is Hardcore: Compare the US Boxart◊ with the European one◊.
- Area of Effect: The Drill Bomb's explosion hits a larger area than the drill itself. Comes into effect against the second Wily Machine, which is weak against the explosion, but resistant against the drill itself, making for some tricky timing.
- It's because the weak spot is just above Mega Man's jump height.
- Auto-Scrolling Level: The third Cossack stage is one of these, a rarity in the series.
- Balloonacy: The Balloon item plays with this trope, making Floating Platforms out of large, red balloons.
- Barrier Warrior: Skull Man. You too, once you recieve his Skull Barrier.
- Behind the Black: Pharaoh Man's level. After the first part, you have to drop down a crevice to continue, but going forward nets you a special item.
- Big Bad: Dr. Cossack. Until we learn that he was a pawn in Dr. Wily's plans.
- Blackout Basement: Parts of Bright Man's level become this if you shoot the 100-Wattons that fly through the area. Shoot a Donpan to turn the lights back on.
- Blinded by the Light/Stun Guns: Although it appears the Flash Stopper makes time stand still, in reality what it does is flash an intense light that blinds and stuns enemies for a short time.
- Bookcase Passage: How the mummy mecha-mooks in Pharaoh Man's stage appear, part of the wall flipping around to reveal them.
- Boss Arena Urgency: Mothraya destroys part of the floor with one of its attacks.
- Bubbly Clouds: Subverted somewhat with Ring Man's stage, which begins in a cloudy tower but then goes into space and is filled with hippos and small floating Saturns. Played straight with the third Cossack stage, which takes place in the sky above the citadel and where platforms are often obscured by clouds.
- Build Like an Egyptian: Were you expecting Pharaoh Man's stage to be anything else?
- Charged Attack: This is the first game that allows Mega Man to charge up his buster. The Pharaoh Shot is this too.
- Checkpoint Starvation: an annoying bug in Cossack Citadel 1, where dying against the Mothraya Boss would send Mega Man back to the midpoint of the level, not in the Boss corridor.
- Cranium Ride: Bright Man's stage has you ride a robotic grasshopper over spikes on a few occasions. Pharaoh Man has a similar gimmick in his level.
- Dem Bones: Skull Man and his stage appropriately have a bone motif. Skeleton Joes are a recurring enemy in this level, and they also appear in the first section of Cossack Citadel.
- Denial of Diagonal Attack: Averted by the Pharaoh Shot, which can be aimed diagonally; played straight with everything else.
- Disc One Final Boss: Dr. Cossack, special note that this is the first Mega Man Classic game to pull this trick.
- Disc One Final Dungeon: Cossack Citadel.
- Distressed Damsel: Kalinka Cossack, who's being held hostage by...Dr. Wily.
- Down the Drain: Most of Toad Man's stage and part of the first Wily level. Dive Man's stage is either this or Underwater Base.
- Dramatic Thunder: Cossack's Siberian Citadel is introduced this way.
- Dual Boss: The Cockroach Twins from Cossack Citadel 3.
- Dummied Out: Pharaoh Man's level was originally supposed to include a Sphinx Mini-Boss on the path to the Balloon Item. This boss did not make it to the final release, and the only data left of the Sphinx was the snake on his forehead, its chin, and some sort of sphere that Mega Man would have stood on during the battle.
- Everything Makes a Mushroom: Dr. Wily's fortress makes a skull-shaped mushroom cloud when it goes up at the end.
- Fast Tunnelling: Drill Man tunnels underground quickly using his many drills.
- Floating Platforms: The Balloon item found in Pharaoh Man's stage makes these.
- Foreshadowing: Wily is only made aware of Proto Man's betrayal at the end of this game, which would lead to the plot of the next installment, where Wily frames Proto Man, possibly as revenge.
- Frogs and Toads: Toad Man (who else?)
- Game-Breaking Bug: It is possible to kill Dr. Wily as he's ejecting from his exploding Wily Machine if you fire the Rain Flush and time it just right, so the rain starts as he's flying out. However, doing this will mess up an Event Flag that ends the level, meaning you're stuck in that room, forcing you to reset. Considering what's the point of entire series, this makes sense.
- Glorious Mother Russia: The Cossacks; Fanon has taken it Up to Eleven.
- Grappling-Hook Pistol: The Wire, found in Dive Man's stage.
- Hijacked By Wily
- Homing Projectile: The Dive Missile.
- Hopping Machine: Toad Man, most of the Robot Masters jump, but Toad Man's only mode of movement is to hop around like a toad.
- Hyper-Destructive Bouncing Ball: The Super Ball Machine Jr., particularly destructive as it fires its giant bouncing balls through the narrow corridors of Skull Man's stage.
- Invulnerable Attack: Drill Man is invulnerable while drilling into the ground, Dust Man is invulnerable while using his Vacuum Mouth.
- Just in Time: Just as Mega Man is just about to finish off Dr. Cossack, unaware that Cossack is actually being forced to fight against his will, Proto Man teleports in with Dr. Cossack's kidnapped daughter, Kalinka, exposing Dr. Wily as the mastermind behind everything.
- Kidnapped Scientist: Dr. Cossack by Dr. Wily
- Ledge Bats: This game introduces Up 'n Downs, an annoying little enemy that hides in Bottomless Pits and jumps out just as you're jumping over them, and can easily knock you in if you're not expecting them. Nearly every game after this has a variation of these guys.
- Losing Your Head: Mummira, the mummy robots from Pharaoh Man's stage, attack by using their mummy bandages to throw their heads at Mega Man.
- Luckily My Shield Will Protect Me: The Skull Barrier.
- The Man Behind the Man: Dr. Wily is the real Big Bad of the game.
- Multi-Mook Melee: Wily Stage 1 which is full of Metools and all their variations followed by....
- King Mook: The Met Daddy, the boss of this stage.
- Nepharious Pharaoh: Pharaoh Man is one of the Robot Masters fought in this game. He's not an actual pharaoh, though he was originally built to explore pyramids. His stage begins as a Shifting Sand Land and progresses into a Temple of Doom.
- Noob Bridge: The Drill Bomb's remote detonation property (one of the reasons its one of the better "explosve" weapons in the series) is often overlooked (push B again before it hits its target). The 2nd Wily ship is basically a test to see if you know about it.
- Offscreen Start Bonus: In the first stage of Dr. Cossack's fortress, there's a hidden E-tank buried in the snow to the left of your starting point.
- One-Wheeled Wonder: Mono Roader
- Precision-Guided Boomerang: The Ring Boomerang - it's even in the name.
- Quicksand Sucks: Part of Pharaoh Man's level involves this.
- Rain Dance: How Toad Man summons his acidic Rain Flush, also his Achilles' Heel as if he's interrupted before his dance is complete, it'll complete negate his Rain Flush.
- Renegade Russian: Subverted in the end; Dr. Cossack's actually a pretty decent guy.
- Reviving Enemy: The Skeleton Joes in Skull Man's stage.
- Rings of Death: The Ring Boomerang.
- Scary Scorpions: The Sasoreenu are scorpion robots found just outside of Pharaoh Man's Temple of Doom, emerging suddenly out of the quicksand to attack.
- Sea Mine: Located in Dive Man's stage.
- Shared Life Meter: The game has the Cockroach Twins, two robots fought one after the other.
- Shout-Out: Mothraya, the first Boss of Cossack's Citadel.
- Skele Bot 9000: The Skeleton Joes that inhabit Skull Man's stage are this. They even reassemble if they're not totally destroyed by a Charged Attack. And Skull Man himself, of course.
- Skull for a Head: Skull Man, obviously.
- Spread Shot: The Dust Crusher is of the Exploding Shot variant.
- Super Hero Origin: Mega Man's origin story had previously been All There in the Manual, but this game goes ahead and puts this in the game's intro.
- Teleport Spam: This is the first game where you fight Wily in his teleporting saucer, and he uses it in every game after this one too.
- This Is a Drill: Drill Man, and by extension the Drill Bomb.
- Trapped In Villainy: Dr. Cossack. Sure, he's not threatened to death, but what about his daughter?
- Unblockable Attack: Rain Flush hits all enemies on the screen, including shielded ones like Metools under their hats.
- Utility Weapon: The Drill Bomb is the only weapon that can destroy those hard walls.
- Vacuum Mouth: Dust Man will attempt to suck in trash (and Mega Man) using the duct on top of his head.
- Warm-Up Boss: Toad Man is the easiest boss this time around. He can't even attack you as long as you keep shooting him.
- You Dirty Rat: The Ratton's in Toad Man's sewer stage.
