''Mega Man'' (''Rockman'' in Japan) is a 1987 NintendoEntertainmentSystem video game by Creator/{{Capcom}}, and is the first game in the eponymous [[VideoGame/MegaManClassic series]] of the same name, as well as its many, many spinoffs.

The story: It is the year [[ExtyYearsFromNow 20XX]], and advanced robots designed to help humans in tasks are commonplace thanks to the efforts of [[BigGood Dr. Light]], the foremost expert on robotics. One day, however, a former friend and rival of his by the name of [[MadScientist Dr. Wily]] reprogrammed several of these robots, and is now attempting to TakeOverTheWorld from within his fortified robot factory. To make things worse, among them are Dr. Light's six Robot Masters - humanoid robots with advanced A.I. and abilities designed for industrial use. Dr. Light's assistant robot and "son" Rock, [[VideoGame/MegaMan4 having a strong sense of justice]], volunteers to be converted into a "fighting robot" in order to disable and retrieve the Robot Masters and right Wily's wrongs. He thus becomes known as Mega Man.

At the time, Mega Man was a revolutionary title in the [[UsefulNotes/NintendoEntertainmentSystem NES]] library; first, you could choose to tackle any stage you wished in any order you desired, second, to add a layer of strategy, the game allowed you to not only [[VictorGainsLosersPowers keep the weapon of whatever boss you killed]], but also allow you to use the weapon in question against [[TacticalRockPaperScissors another boss that was particularly weak to it.]] The game's cartoony graphics and catchy music, not to mention its [[NintendoHard grueling difficulty]], established many hallmarks that we've grown to love about the series.

The game was ultimately a modest hit in Japan, but performed rather poorly in sales in the United States, which made Capcom reluctant to make another sequel, but they ultimately [[VideoGame/MegaMan2 greenlighted one anyway...]]

It is worth noting that while in its planning stages, Capcom planned on basing the original game on ''Anime/AstroBoy'' but when those plans fell through, the developers put Keiji Inafune in charge of creating brand new character designs. Another early idea for the game was to make it an arcade platformer called ''Rainbow Man''. Other proposed early titles included ''Mighty Kid'' and ''Knuckle Kid''. The game was developed by a small team of six people, with Keiji designing almost all of the characters and enemies and sprites. The game also gave them a lot of headaches as far as memory limitations went--the entire cart was only 1 Megabit (1000 kilobits, or 128 kilo''bytes'') in size!

The game would later receive a [[UpdatedRerelease 16-bit upgrade]] in the [[NoExportForYou Europe and Japan exclusive]] ''Mega Man: The Wily Wars''/''Rockman Megaworld'' cartridge for the UsefulNotes/SegaGenesis (Aside from a brief US release as a downloadable Sega Channel exclusive, and an eventual local release as a bundle with other Sega games in a portable Sega Genesis re-release, the Sega Genesis Ultimate Portable Player.). It would later be ported to the [[UsefulNotes/PlayStation PS1]] as ''Rockman: Complete Works'', and then to the [[UsefulNotes/PlayStation2 PS2]], UsefulNotes/NintendoGameCube and UsefulNotes/{{Xbox}} as part of ''Anniversary Collection''. It has also seen a release on UsefulNotes/VirtualConsole. This game also received a [[VideoGameRemake remake]] for the [[UsefulNotes/PlayStationPortable PSP]], called ''VideoGame/MegaManPoweredUp''.

Robot Masters:
* DLN-003: Cut Man, weak to Super Arm, gives you [[BattleBoomerang Rolling]] [[AbsurdlySharpBlade Cutter]]
* DLN-004: Guts Man, weak to Hyper Bomb, gives you [[SuperStrength Super]] [[RocksFallEveryoneDies Arm]]
* DLN-005: Ice Man, weak to Thunder Beam, gives you [[FreezeRay Ice Slasher]]
* DLN-006: Bomb Man, weak to Fire Storm, gives you [[HavingABlast Hyper]] [[CartoonBomb Bomb]]
* DLN-007: Fire Man, weak to Ice Slasher, gives you [[PlayingWithFire Fire]] [[KillItWithFire Storm]]
* DLN-008: Elec Man, weak to Rolling Cutter, gives you [[ShockAndAwe Thunder]] [[LightningGun Beam]]

This game would later receive a companion title for the GameBoy, called ''VideoGame/MegaManDrWilysRevenge''.


* AbilityRequiredToProceed: Didn't pick up the Magnet Beam in Elec Man's level? You won't reach the end of the first Wily stage without it, so get a GameOver to get back to the stage selection screen and go get it!
* AllThereInTheManual: The game's story, as per the standards at the time. However, the US version is notoriously inaccurate ("robot-like humanoids"?).
** Both the US and Japanese manuals fail to mention Roll in any manner, making her appearance in the game's ending out of nowhere.
** Most summaries and adaptations of the story tend to imply Wily was banking exclusively on the six Robot Masters in conquering the world. A short manga initially only seen to those who won the ''VideoGame/MegaMan4'' boss character contest shows that Wily reprogrammed a heck of a lot more than just six robots (as in, the minor enemies were a more immediate concern than the Robot Masters).
* AmericanKirbyIsHardcore: One of the most infamous examples, due to the artist being given only the back of the box description and a couple of ''hours'' with no source material to work with. Thus the North American version instead got [[https://supermemorybros.files.wordpress.com/2012/07/megaman-boxart.jpg a middle-aged man in a blue and yellow jumpsuit, holding a pistol, against a rather bizarre background.]] [[http://www.blogcdn.com/www.nintendowiifanboy.com/media/2008/09/boxart-mm1-eu.jpg The European boxart]], while more accurate to the game, also qualifies.
* AnIcePerson: [[CaptainObvious Ice Man.]]
* {{Antepiece}}: Because you can enter each level in any order, the developers carefully planned each one around a specific gimmick as a warmup for the Robot Master encounters, while also doubling as red flags for whats up ahead as far as the games difficulty goes.
** Cut Man has a flying enemy (Bunby Heli) that launch at you in an arc, which you have to shoot or time your jumps carefully in order to dodge, a warm up for Cut Man and his Rolling Cutter.
** Guts Man has its first section centered around a wide open pit with traveling platforms moving along, requiring very precise timing to dodge. Later on, you'll need these kind of jumping reflexes to avoid getting knocked on your butt by Guts Man's earth shaking stomp and dodge his subsequent boulders. You also encounter the Metall enemies before you fight their tougher Pickelman counterpart.
** Elec Man has electric arcs that shoot out at you, inflicting heavy damage on contact. These are a tip that Elec Man is by far the toughest of all the bosses. Also, the opening room has a series of platforms guarded by enemies (Spines) that can only be stunned with the Mega Buster (but can be destroyed with the Rolling Cutter later) a clue of just how hard it will be to get all the way up the tower. It's also a vertical oriented stage with lots of opportunities to fall, so the dev team placed the Magnet Beam in it to encourage you to try out practicing with it to make the stage easier, and prepare you for using it later in the final Wily stages.
** Fire Man has a section close to the end where a constant stream of fire is pouring out of a tunnel, and it requires pixel perfect timing to dodge them. You encounter this exact same problem with Fire Man and his barrage of the Fire Storm.
** Ice Man's use of Appearing Blocks and very difficult floating platforms is a cue for you to try out finding or using the Magnet Beam to pass, since its required to beat the game later anyway.
** Bomb Man's stage, besides the presence of exploding bombs flying out of pits, has the Flea enemies jump in the exact same arc that Bomb Man does, serving as a warm up for your fight with him later.
* ArtificialStupidity:
** While Elec Man is one of the toughest bosses in the game (especially if you fight him without his weakness), it's possible to exploit his crude AI by jumping and shooting him in a very carefully timed pattern, freezing him in place while also allowing you to dodge his attack.
** Use the Super Arm or Magnet Beam against the Copy Robot, and watch as it continually runs left to right, never touching the far left corner and only jumping when the shoot button is pressed. It is worth noting the boss recycles the aforementioned Elec Man's AI.
* AscendedGlitch: The "Pause Trick" is so well known that in the ''Anniversary Collection'' port, the glitch was deliberately left intact. Even moreso in the ''Legacy Collection'' where not only is it intact, but the expected way to get a gold medal on the time trial for Yellow Devil is to Pause Trick him.
* AwesomeButImpractical: The Hyper Bomb. It's extremely powerful, but there's such a long delay between the time you throw it and when it actually goes off, that it's very easy for the enemy to move out of range before that happens. Also, you can only throw one bomb at a time, so you're left wide open if you miss.
* BlobMonster: The Yellow Devil.
* {{Bowdlerise}}: Due to Nintendo's policies discouraging any religious references, Western sources at the time (such as ''Magazine/NintendoPower'') refer to the Yellow Devil as the "Rock Monster".
* BossArenaIdiocy:
** Cut Man is weak to having Super Arm blocks thrown at him. There are blocks in his arena. Oops. Subverted when refought in Wily's factory, making him the one Robot Master in the series whose weakness can't be used against him in a rematch.
** The same goes for CWU-01P in the third stage of Wily's factory, but notably if you use too many blocks too early, you'll find yourself hard-pressed to avoid damage from the large and progressively faster robots (Boss Arena Brilliance?).
* BossRush: Played quite differently than the later games (aside from ''VideoGame/MegaManX1'' and ''VideoGame/MegaManAndBass'', both of which brought it back). Instead of all the Robot Masters being fought in a contained room, they're fought separately across levels.
* CartoonBomb: [[CaptainObvious The Hyper Bomb]], both for you and Bomb Man.
* ContemptibleCover: [[http://upload.wikimedia.org/wikipedia/en/d/dd/Mega_Man_1_box_artwork.jpg The North American box art]]. It even got a throwback in ''VideoGame/MegaMan9'' and ''VideoGame/MegaMan10'', whose Western "box art" deliberately invoke this.
* CoversAlwaysLie: The infamous American box art would have you believe that you play as a 50-something man in a bright blue and yellow suit while holding a gun, and it all happens in a city with palm trees, large metal buildings and bright gold arses littered everywhere. Suffice to say, none of that may be true in the actual game.
* CutAndPasteEnvironments: The environments tend to look very similar and tiles and enemies frequently rely on palette swaps. The dev team only had 1 Megabit (1000 kilobits, or 128 kilo''bytes'') of memory to work with, forcing them to use every shortcut they could just to fit the game in, including this trope.
* DittoFighter: The Copy Robot copies Mega Man and uses whatever weapon he uses. It also acts like one to Elec Man, since it reuses his AI.
* DubNameChange: The reason for the change from ''Rockman'' to ''Mega Man'' was because Capcom Consumer Products Division president Joe Morici felt the title was horrible.
* EarlyInstallmentWeirdness: Plenty of it. Let's see: There's a [[ScoringPoints point system]], only six Robot Masters, small, sparse stages, the {{Boss Corridor}}s are longer and contain enemies, weapon and energy items look different than they do in later games, no [[EmergencyEnergyTank E-Tanks]], no [[PasswordSave password function]], MercyInvincibility won't protect you from the SpikesOfDoom, after defeating each boss, you have to grab an orb (which the [[http://kobun20.interordi.com/2012/12/12/the-rock-manual/ Japanese manual]] implies to be the robot's "central core", or as later supplementary material would use, IC chip) to finish the stage proper, Mega Man doesn't even teleport out afterwards, there's no "Weapon Get" screen, Wily's lair is a robot factory instead of a [[SupervillainLair castle with a skull motif]], it doesn't have a map screen, the Robot Master rematches are sprinkled throughout its stages instead of being collected in a teleporter room, and the Wily Machine is the FinalBoss rather than being a penultimate boss in the other games. Also, half of the weapons were thrown rather than being shot out of the Mega Buster, there are no Rush items, collectible powerups reappear when you leave the screen and return (thank goodness!), Dr. Light's name was initially translated as [[SpellMyNameWithAnS Dr. Wright]] in the manual, Mega Man's movement is slightly slippery and he does not jump higher underwater. Phew!
** The "feel" of the game is also very different from its sequels. Mega Man has noticeably less traction, almost as if every surface in the game is covered in oil. He is also missing the slide move, which became a standard feature from the third game onward.
** In this game and Mega Man 2, most of the common sound effects (for example, firing and doing enemy damage) are different than in the rest of the series. Much of the soundtrack is much lighter in tone, as well.
* ElementalBaggage: Guts Man and his Super Arm play this straight; Mega Man, however, [[RequiredSecondaryPowers does not]].
* EternalEngine: Elec Man's stage.
* ExcusePlot:
** Mad scientist Dr. Wily is taking over the world with a batch of stolen robots, go stop him!
** The Wily Wars port plot is centered on Dr. Wily stealing a time machine and trying to take down Mega Man in the past, prompting Dr. Light to send Mega Man back in time to fight him while reliving his first adventure. Of course, that plot point is exclusive to the manual--the in-game plot is as bare bones as ever.
* {{Expy}}: As noted earlier, Mega Man was heavily patterned after [[Manga/AstroBoy Astro Boy]], since the game was originally planned to be an ''Astro Boy'' game. This is especially notable in the ending, where Rock is almost a dead ringer for him.
* FireIceLightning: Fire Man, Ice Man, and Elec Man, respectively. Naturally, Mega Man will wield all three of their weapons after you defeat them.
* GameBreakingBug: The final battle has a real show-stopper; if you get hit by the final boss ''at the same moment'' when you defeat him (so both of you take damage on the same frame), the screen will glitch and the game will never proceed to the ending, forcing you to reset the game.
* HeartDrive: That red orb that appears after defeating a Robot Master is this, an apparant early version of what supplementary materials would call an I.C. chip.
* INeedNoLadders: The ladder climbing animation is slightly bugged, resulting in a glitch where Mega Man simply ''falls up'' very quickly under certain conditions, and is one of the ways to save time in speed runs.
* ItsAllUpstairsFromHere: Elec Man's stage, and part of Cut Man and Bomb Man's stages. The final Wily stage also goes upwards as the BossRush is progressed.
* KaizoTrap: Just about any boss in the game can cause this. Unlike other games in the series, the boss' projectiles do not disappear when they're defeated, and can still hit you. This is especially problematic because Mega Man is frozen briefly when the boss explodes. It is entirely possible as a result to die after beating the boss, which of course results in having to fight them all over again.
* LethalLavaLand: Fire Man's stage, though the actual lava isn't much to write home about (essentially being a fancy background over a large bottomless pit).
* LongRangeFighter: Fire Man only uses the Fire Storm when he is far enough away from Mega Man (or when Mega Man shoots). If Mega Man is too close, he will try to run away from him. Stay close to Fire Man, and he becomes several times easier.
* NintendoHard: One of the hardest of the original games, for the following reasons:
** No password or save function--the game must be completed in one sitting (Except on Virtual Console, which lets you quit with the home button and come back right where you left off (and lets you "save state" on the Wii U and 3DS), and Anniversary Collection gives an auto-save). The game is at least generous enough to give you infinite continues and checkpoints. ''Legacy Collection'' had built-in save states similar to an emulator.
** MercyInvincibility does not protect you when you fall onto spikes.
** Tricky platforming segments; most notably in Guts Man and Ice Man's stages, where there are platforming bits that demand split-second reflexes and very precise jumping, with absolutely no room for error. Ice Man's stage is possibly the hardest of all the stages, not only due to the disappearing blocks, but also the erratic pattern of the flying platforms midway through the stage (not to mention the fact that they shoot at you, which combined with how small they are, makes it extremely easy to get knocked off to your death), not to mention the occasional glitch that keeps the platforms flying too far apart from each other, will have all but the most determined players falling back on the Magnet Beam to skip through.
** Very cheap placement of powerful enemies such as Big Eyes, particularly in Wily Stage 1.
** Boss weapons are a lot less useful than in the later games outside being used against bosses.
** Some of the bosses have much more erratic patterns, not to mention much more damaging, "take you down in one or two hits" attacks -- Elec Man and Ice Man are the most infamous for this, as they can both kill you in three hits. Their attacks are often difficult, or, in the case of Fire Man or Ice Man, almost impossible to dodge.
** The aforementioned kaizo traps that can sometimes occur just when you have defeated a boss.
** Health pickups aren't as common as in later games, and the game contains useless pickups that only increase points.
** The infamous Yellow Devil, which many people have not been able to defeat without exploiting the "Pause Trick" glitch.
** The Wily Wars port adds a save feature and mercy invincibility for spikes, and makes the Yellow Devil fight easier due to the lag during its morphing, but as a trade off the robot masters take and dish more than ever, and there's no pause trick.
* NoOSHACompliance: Good Lord, Wily's Robot Manufacturing Plant. It may as well be a DEATH Manufacturing Plant!
* NoPlotNoProblem: Because the game had very little memory to work with, the plot is entirely in the manual--the game just drops you off at the title screen so you can get straight to whomping Wily's robots upon pressing start. The ending is the only indication that there even was a story in the first place.
* NoSidepathsNoExplorationNoFreedom: All of the stages are very straightforward, with no alternate paths or hidden secrets (aside from the Magnet Beam, but it's not hidden and [[AbilityRequiredToProceed it's mandatory]]) to look for.
* PaletteSwap:
** Because of the NES' limitations, certain enemies have color differences between levels, though none of them act any different or are passed off as another enemy.
** An odd example is the Copy Robot - while it's not a recolor of anything, its battle A.I. (aside from what weapon it uses) directly reuses that of Elec Man's thanks to the cartridge's memory limitations.
* PlayingWithFire: [[CaptainObvious Fire]] [[RunningGag Man]].
* PowerUpLetdown: The Super Arm is by far the least useful of all the weapons you get. It can only be used in specific situations where you can grab a giant block and throw it. Other than the battles with Cut Man (but only the first time) and CWU-01P and getting to the Magnet Beam, it's basically useless.
* PrecisionGuidedBoomerang: The Rolling Cutter.
* PuzzleBoss: The third Wily Stage boss, the [=CWU-01Ps=], sort of.
* ScreenShake: Happens everytime Guts Man jumps. Mega Man has to time his jump or it will briefly knock him off his feet, leaving him open for attack.
* SharedLifeMeter: The game has CWU-01P, a series of robots encased in bubbles. Each one has its own hit points, but destroying one will always knock off four bars from the shown boss meter.
* ShoutOut:
** The Killer Bomb enemies seem obviously patterned after [[VideoGame/SuperMarioBros1 Bullet Bills]].
** The Yellow Devil's appearance is heavily based on the giant robot Astro Boy fights on the moon in the early "Hot Dog Corps" story arc of the manga. The design similarities would become even more blatant in [[VideoGame/MegaMan3 its later reappearance.]]
* SlippySlideyIceWorld: Ice Man's stage. Notably, it has palm trees in the background, implying it's an odd arctic version of JungleJapes.
* SpikesOfDoom: Setting the standard for the series, spikes that insta-kll you are everywhere, and unlike later games, MercyInvincibility ''won't'' save your blue ass if you fall into them.
* StuffBlowingUp: Naturally, all over the place in Bomb Man's stage, with Bombombombs that self-destruct and drop explosve fragments, Killer Bombs that cause a harmful explosion after being shot, and of course Bomb Man himself.
* SuperNotDrowningSkills: Water won't kill Mega Man, though to be fair he ''is'' a robot.
* SuperStrength: Guts Man has this as his ability, being able to summon and throw huge boulders at you. Defeating him gives you the Super Arm, which allows you to lift up certain blocks and throw them (but you can't summon blocks yourself).
* TrialAndErrorGameplay: In the Guts Man level, there is an area where you have to fall downward onto to the next screen, while avoiding the SpikesOfDoom which cause instant death upon contact. There is absolutely no way to know where the spikes are your first time playing the game. If you manage to get past this part without dying, it's entirely due to luck.
* WalkDontSwim: Mega Man can't swim, but whereas in the sequels he can jump ludicrously high in water, in this game it slows him down and weakens his jump. The ''Wily Wars'' port, curiously, ignored that and kept the water physics the same as the sequels.
