[[caption-width-right:335:Betcha can hear the title music just by looking at this. If you can't, [[http://www.youtube.com/watch?v=DOQhuuG1rfs then listen]] [[http://www.youtube.com/watch?v=4HE8uzfCcoo anyway.]]]]

->''[[TwentyMinutesIntoTheFuture In The Year Of]] [[ExtyYearsFromNow 200X]], A Super Robot Named Mega Man was created. [[BigGood Dr. Light]] created Mega Man to stop the evil desires of [[BigBad Dr. Wily]]. However, after his defeat, Dr. Wily created eight of his own robots to counter Mega Man.''
-->--[[http://www.youtube.com/watch?v=N8Ao63nmzuE The intro to the game]], [[ExcusePlot summing up its entire story.]]

''VideoGame/MegaMan2'' (''Rockman 2: The Mystery Of Dr. Wily'' in Japan) is a run and gun {{Platformer}} VideoGame, released by {{Capcom}} for the {{NES}} in 1989 (1988 in Japan).

While the core gameplay of beating bosses in a non-linear order while [[PowerCopying acquiring their weapons]] to use against another boss a la [[ElementalRockPaperScissors rock, paper, scissors]] is largely the same, many changes have been made to make the gameplay far more flexible and accessible to gamers than the original. Two difficulty settings and a new password function are present, three items and E-Tanks are around to make the game far more forgiving in difficulty. The new boss roster has been bumped up to eight robots rather than six, and the stage designs are far more ingenious than before. The presentation has also been taken up a notch, with lushly designed stages, better spritework, a cartoony plethora of enemies cribbed from design contests, and some [[AwesomeMusic/MegaMan energetic 8-bit tunes]] to top off the sundae. The scoring system from the original was permanently dropped, but it wasn't missed. All in all, it manages to top the original in just about every way.

While the [[VideoGame/MegaMan1 original game]] was only a modest hit, this sequel became the best selling game in the entire Mega Man series, selling over 1.5 million copies. To this day, it is considered not only one of the best {{NES}} games and one of the best games (if not ''the'' best game) in the entire series, but also one of the greatest video games of all time. Keiji Inafune himself even said that Mega Man 2 is his [[MagnumOpus favorite Mega Man game]].

The game later received a [[UpdatedRerelease 16-bit upgrade]] for the SegaGenesis, as part of the [[NoExportForYou Europe and Japan only]] ''Mega Man: The Wily Wars''/''Rockman Megaworld'' cartridge, as well as the Japan-only ''Rockman 2: Complete Works'' PS1 port. The game eventually saw a major rerelease as part of ''Anniversary Collection'' for PS2, GameCube and {{Xbox}}. The NES version has also received a VirtualConsole re-release on the {{Wii}}, and then years later on the [[Nintendo3DS 3DS]], the latter even coming with a [[SaveScumming save state]] ability. The ''Wily Wars'' port eventually saw a US release, albiet as a bundle with many other games in a portable SegaGenesis re-release, the ''Sega Genesis Ultimate Portable Player.''

----
!!Tropes:

* AbnormalAmmo:
** Mega Man himself gets to use bubbles, leaves and mini-tornadoes.
** Many enemies use thematic ammo: Rabbit-shaped robots fire carrots, Pipis drop eggs that spawn small robotic birds, Croakers fire small frogs and Lightning Lords throw lightning bolts (not actual bolts of lightning, mind you, but javelin-like projectiles that look like lightning bolts).
* AdvancingBossOfDoom: The Mecha Dragon in Wily Stage 1. Doubles as AdvancingWallOfDoom, as touching him has exactly the same effect as spikes or kill-beams.
* AirborneMook: Air Man and Crash Man's stages in particular are full of these.
* AmericanKirbyIsHardcore: The US boxart features adult sized musclemen dressed up as Mega Man, Quick Man and Crash Man in a airbrushed futuristic setting. While cheesy, it's nowhere near as infamous as the first game's box art, mainly because it at least bears ''some'' resemblence to the actual game. And that is nothing compared to the downright nightmarish Magazine/NintendoPower [[http://www.comiccollectorlive.com/LiveData/Issue.aspx?id=589ad315-052b-455d-b013-f0de8c4196e4 cover of Mega Man 2]]; clay figure Dr. Wily looks downright ''terrifying''!
* AnimalMecha: The bats, hot dogs, gorillas, rabbits and roadrunners in Wood Man's stage.
* AnimeHair: Mega Man in the opening.
* AngryGuardDog: The Hot Dogs in Wood Man's stage.
* ArtEvolution: The game's art started to become more anime-influenced than the previous game, and the spritework is more refined.
* AutoScrollingLevel: The final part of Wily Stage 1.
* AwesomeButImpractical: Heat Man's weapon is very powerful and looks cool when fully charged, but it chews up so much ammo, and it's so easy to get its charge cancelled by an attack, that it's best used sparingly, and otherwise its normal shot is so pathetically weak that it's all but useless. Time Stopper is also only really useful in Quick Man and Wood Man's stage, as it consumes ammo quickly and Mega Man can't attack or change weapons while using it.
* BattleBoomerang: Quick Man's weapon of choice.
* BeneathTheEarth: Just before the [[spoiler:actual]] final boss.
* BittersweetEnding: Though there is no text narration in the ending cutscene, the somber tone of the soundtrack suggests that Mega Man feels quite alone and confused, having shouldered the task of fighting his own kind "for everlasting peace". [[GainaxEnding Then again, your guess is about as good as anyone's...]]
* BlowYouAway: The main attack of Air Man, as well as a few of the mooks throughout his stage.
* BootstrappedTheme: The famous title screen music is generally regarded as Mega Man's main theme song. So is the Wily Stage 1 music.
* BoringYetPractical: The Mega Buster, due in part to its quick firing, infinite ammo and being able to kill some enemies that are immune to the Metal Blade, and the 3 "Items", which are essential for beating the game.
* BossRush: Just before the [[spoiler:[[DiscOneFinalBoss fake]]]] final boss. And for the first time, the boss doors are all in one room, rather than one after the other.
* BottomlessPits: Notably in the Metal Man and Skull Castle stages.
* BubbleGun: Bubble Man's weapon of choice, Bubble Lead.
* BullfightBoss:
** Heat Man charges towards you after being hit.
** Quick Man who mostly hurts you via CollisionDamage.
* ChargedAttack: Atomic Fire, predating the charged buster of ''VideoGame/MegaMan4''.
* CollisionDamage
* ContinuingIsPainful: [[ZigZaggedTrope Zig-zagged]], in that a continue refills all weapon energy but also costs you all your E-Tanks.
* CoolHelmet
* CoresAndTurretsBoss: The boss of Skull Castle 4, Buebeam Trap.
* DeadlyDisc: Metal Man's weapon of choice, a series of flying buzzsaws.
* DenialOfDiagonalAttack: Every weapon that isn't the Metal Blade or Quick Boomerang.
* DifficultyByRegion: The Japanese and Wily Wars releases are much harder than the US release, the latter of which included a "Normal" mode which doubled how much damage you did to bosses.
* DiscOneFinalBoss: [[spoiler:The Wily Machine.]]
* DiscOneNuke:
** The Metal Blade, unquestionably the most powerful weapon in the game, and one of the most powerful in the entire series; it delivers high damage and can cut through multiple mooks at a time, has a machine gun rate of fire, fast speed and long range, the ability to shoot in eight directions, [[RuleOfCool a cool appearance]], and an ammo capacity so ridiculously large that would take a conscious effort to deplete it! And on top of all that, besides the boss you get it from being very easy to beat (meaning you can get it practically from the start of the game), it's the only weapon in the game that, some more than others, works effectively against all the robot masters (it's a major weakness for four of them and the second-to-last boss, and it even kills its own boss with ''one shot''). If it weren't for it's sole handicap of several enemies being immune to it, it would make the Mega Buster all but obsolete!
** Quick Boomerangs, while nowhere near as impressive, aren't a bad substitute. They too have a ton of ammo, and while the range isn't quite as good as the Metal Blade, the arc they travel in makes it easier to hit things above and below that the buster can't. The original release of the game also gave Quick Boomerangs an extra bit of utility thanks to a bug that was not caught before it shipped; Quick Boomerang would damage any stage enemy (but not necessarily the bosses) without fail, including some otherwise invulnerable enemies. This was fixed in the ''Wily Wars'' rerelease.
* DoNotTouchTheFunnelCloud: Air Man's weapon is a SpreadShot of mini-tornadoes.
* DramaticThunder: In the Skull Castle map screen.
* DungeonBypass: The numbered items. Item-2 in particular can be used to bypass several tricky obstacles.
* EasterEgg: Holding B when you select a boss will cause the stars on the bosses intro screen to turn into birds.
* EasyLevelTrick: On the very last stage, hold right and keep going. You will be ahead of all the lava/acid drips that you don't need to time your movements.
* ElementalBarrier: Wood Man's Leaf Shield.
* ElementalPowers: This game (almost) has the five Chinese elements (Fire, Water, Wood, Metal) and the four classical elements (Fire, Water, Wind).
* ElementalRockPaperScissors: Played with in this game. While there is a clear circular line of weakness, most of the bosses have at least another one (mostly Metal Blade) that they're weak against. This is one of the few Mega Man games were it can be considered open-ended.
* EmergencyEnergyTank: This was the first game in the series to give you E-Tanks, which can instantly refill your health on the go, and were essential to toning down the difficulty of the original game.
* EpilepticFlashingLights: The fortress bosses in paticular; when fighting the Mecha Dragon, Guts-Dozer, Wily Machine [[spoiler:and the alien]], the whole screen flashes white ''every time they take damage''. After defeating them, the screen continues to rapidly flash while they fade out. The screen does not flash while fighting the Picopico-kun and Boobeam Trap, although it still rapidly flashes after they're defeated. The [[Nintendo3DS 3DS]] Virtual Console version tones down the screen flashing, although it may be because of different screen refresh rates.
* EverythingsBetterWithMonkeys: The gorilla robots from Wood Man's stage.
* ExtyYearsFromNow: As mentioned into the intro.
* ExcusePlot: Dr. Wily is back for revenge with a batch of his own robots to counter Mega Man. Go at it!
* FanFare: The iconic Mega Man theme at the title screen, as well as the "Boss Selected" music. Finally, there's the triumphant victory theme after defeating the final boss.
* FatalFlaw:
** Why does Quick Man keep running into the wall? His sight sensors can't keep up with his speed.
** Apparently the reason why Metal Man is allergic to his own weapon is that he's lightly armored. [[FridgeLogic This does nothing to explain the other bosses though]].
* FlashOfPain: The minor enemies very breifly flash white when being hit. The Robot Masters and Mega Man himself also blinks in and out during MercyInvincibility. See also EpilepticFlashingLights above.
* {{Flight}}: Wily's Alien form is capable of this [[spoiler: by virtue of a floating holosphere.]]
* FragileSpeedster: Quick Man, who takes double damage from the mega buster.
* FrickinLaserBeams: Quick Man's stage has most of itself filled with long lines of rooms where you have to outrun giant, instant kill laser beams.
* GameMod: More rom hacks exist of ''2'' than any other game in the series (possibly more than all of the other games ''combined'').
* GlassCannon: Wood Man. His leaves do a lot of damage, but he has the most weaknesses of all the Robot Masters and takes a lot of damage from all of them.
* GreenThumb: Wood Man's ability is to use a ring of leaves as shields and weapons.
* HairRaisingHare: The robot rabbits from Wood Man's stage, although their only means of attack is shooting carrots at you.
* HoistByHisOwnPetard: Metal Man is killed in one hit by his own weapon (two on Difficult).
* HollywoodAcid: Presumbly what is dripping from the ceiling in the very final level, judging by the high damage it inflicts on Mega Man.
* HumongousMecha: The Guts-Dozer you meet in Wily Stage 3.
* ImprobableWeaponUser: Bubble Man (shoots both bubbles AND fishbones) as well as the robot rabbits from Wood Man's stage (carrots).
* InconvenientlyPlacedConveyorBelt: Notably in Metal Man's stage, AND in his boss room.
* InstantAwesomeJustAddDragons: The boss of the first Wily Stage, Mecha Dragon.
* InvincibleMinorMinion: The Mets, and the Screw Bombers. Unless you use Bubble Lead on said Screw Bombers.
* JokeWeapon: Bubble Lead, which is only useful for beating Heat Man, one of the Skull Castle bosses, and the [[spoiler:final,]] final boss. It's also useful in detecting the fake floor traps in Wily Stage 4.
** LethalJokeWeapon: And for defeating Robbits in Wood Man's stage. And for defeating Springers. And for defeating most enemies generally below you. Truth be told, the Bubble Lead isn't a terrible weapon. It just suffers from the same issues that most of the weapons in ''2'' do: whatever it can do, the Metal Blade can usually do better.
* KillItWithFire: Wood Man's biggest weakness is against Heat Man's weapon, with a fully charged shot able to one-shot him on American difficulty.
* KillItWithWater: Heat Man's weakness, as well as the weakness of the [[spoiler:actual]] final boss.
* LaserHallway: Taken UpToEleven in Quick Man's stage, where the bulk of the stage has Mega Man evading giant, instant-kill laser beams.
* LavaPit: In Heat Man's stage, although that may actually be super heated water, due to the setting being a sewer.
* LogicalWeakness: Wood Man, despite being a robot, is weak to Heat Man's weapon. Heat Man, however, is naturally weak to Bubble Man's weapon. Bubble Man's weakness to the Metal Blades also makes sense as bubbles do not react well to sharp stuff. Quick Man, meanwhile, is weak against the Time Stopper.
* MalevolentArchitecture:
** The Skull Castle stages are a particular standout. Heat Man's stage also has this with its [[MemeticMutation infa]][[EarWorm mous]] row of disappearing blocks.
** The Pico Pico Master, in which pieces of the surrounding room fly out two at a time and combine together to form flying robots that attacks [[CollisionDamage by trying to fly into Mega Man]].
* MascotMook[=/=]TheGoomba: Mets.
* MiniMecha[=/=]HoppingMachine: The Sniper Armor. The latter also applies to the robo-rabbits from Wood Man's stage.
* MinusWorld: The glitchy version of Skull Castle stage 2, which is accessed via a glitch in Air Man's stage.
* MissionPackSequel
* MisplacedWildlife: Gorilla robots in what looks like a mid-western forest?
* MusicalNod: The first part of the game's opening theme is a remix of the first part of the previous game's ending theme.
* NintendoHard: While the games difficulty is much more forgiving than the original game, some parts of the game are still very challenging to beat, especially if you try to beat certain levels and bosses without the most helpful item or weapon. Difficult mode only ramps up the challenge even more. This was unarguably a part of this game's appeal.
* NotEvenHuman: The final boss reveals that Wily was an alien the whole time! [[spoiler: Or not, since it was just a hologram.]]
* NothingIsScarier: The very final level has no music, and the only objects prior to the final boss are the echoing drips of acid from the ceiling...
* NoWaterproofingInTheFuture: How Mega Man is able to defeat the Wily Alien [[spoiler: (which is really just a hologram projector).]]
* NoPronunciationGuide: The Bubble Lead. Is it Lead as in "to lead" (since it trails ahead of Mega Man) or Lead as in the element Lead (since it's a bubble that sinks in all cases)? [[spoiler: In the Japanese script for the weapon they use the word "Rīdo", which means both "water reed" and "to lead".]]
* OneHitKill:
** The spikes as usual. The lasers in Quick Man's stage will do this to you.
** Mega Man can do this himself to several bosses (on normal difficulty). Wood Man can be downed by a fully charged Atomic Fire. Crash Man can be done in with a properly placed Air Shooter. Quick Man can be destroyed by [[ArtificialStupidity running into the same properly placed Crash Bomb over and over]]. And the second time you run into Metal Man, [[WeaksauceWeakness he can be downed by a single Metal Blade]]. On Difficult difficulty, you'll need two hits in most cases.
* OneWingedAngel: Wily pulls this by turning into an alien in the final boss battle! [[spoiler: Of course, that was just a hologram.]]
* OurDragonsAreDifferent: The Mecha Dragon is a robot [[AllThereInTheManual with a blimp built into its body.]]
* OutsideTheBoxTactic:
** Returning Sniper Joes in Sniper Armor are very vulnerable to the Air Shooter and several HumongousMecha are vulnerable to boomerangs.
** During the BossRush portion of the same game, Metal Man dies to one hit of [[PowerCopying his own weapon]] on Normal difficulty, two hits on hard.
* PetalPower: Wood Man's Leaf Shield.
* PlatformBattle: The fight against Mecha Dragon in Skull Castle 1.
* PlayingWithFire: Heat Man, and Mega Man himself when [[PowerCopying he gets his weapon]].
* PowerupLetdown: Most if not all of the weapons the player obtains are less potent than their boss versions. Time Stopper is the most noticeable example; while Flash Man can fire while using it and can use it multiple times, the player can only use it once before having to seek ammo and can't fire while using it.
* PunnyName: The giant, fire-breathing dog robots in Wood Man's stage are called Hot Dogs.
* PuzzleBoss: The Buebeam Trap.
* RecycledSoundtrack: ''9'' would later recycle six songs directly from this game, including [[RecurringRiff the stage opening theme]].
* RegeneratingHealth: Using the wrong weapons on some bosses will replenish their health. [[spoiler: In the Alien's case, EVERY weapon but the Bubble Lead regenerates its health.]]
* RubberForeheadAliens: Wily's OneWingedAngel in the final battle.
* SequelDifficultyDrop: Due to the addition of more utility items, [[EmergencyEnergyTank Energy Tanks]], and a password save system; plus an actual Easy Mode in the North American version (there called "Normal", but the "Difficult" mode is actually the original difficulty).
* SequelEscalation: Quite.
* SharedLifeMeter: The game has the Boobeam Trap and Picopico-kun in Wily's Castle, the former being a series of turrets on the walls that all have to be destroyed, the latter featuring wall panels that combine into flying robots.
* ShoutOut:
** Heat Man looks like a human-sized Zippo lighter.
** There are a batch of enemies in Bubble Man's stage that look uncannily similar to Franchise/{{Metroid}}s, especially since both games were released in the same year. Though it was most likely a coincidence, as they're supposed to be [[{{Expy}} Expies]] of the CWU-01P boss in the first game.
** In the Japanese version, the Hot Dogs are called [[Anime/NeoHumanCasshern Friender]].
* SmashingHallwayTrapsOfDoom: In Metal Man's stage, and Skull Castle 2.
* SolidClouds: There are solid clouds in Air Man's stage. Subverted because you can blatantly see a propeller under it and there is a solid platform one layer behind the cloud.
* SpamAttack: The Quick Boomerang.
* SpikesOfDoom: Particularly in parts of Bubble Man's stage (and his boss room, where they're attached to the ceiling) and Wily Stage 3 (which has a 5-screen long pit lined with the same kind of spikes, with the water physics the only thing that can help you).
* SpreadShot: Air Man's weapon, the Air Shooter. Flash Man fires out a Spray Burst variant after using the Time Stopper.
* [[SittingOnTheRoof Standing On The Roof]]: Mega Man, in the opening.
* SupervillainLair: Skull Castle.
* TankGoodness: Guts-Dozer.
* TemporaryPlatform: Both malevolent and benevolent, both of the "Timed" variety. Heat Man's stage brings back the infamous disappearing blocks (Yoku Blocks). The three Items you get in the game serve as helpful platforms. Can be also considered as NoobBridge, as most people find this long section of Yoku Blocks very difficult, and often chooses to use Item 2 to get through. It doesn't help that an extra life is teasing you midway through it. This is also the point where people get stuck in a loop: To get past the Yoku Blocks they need to get Item 2 from Air Man, Air Man is painfully difficult to fight because he blocks your shots with an Air Shot wall that he sends at you (Some patterns being utterly unavoidable), Air Man's weakness is the Leaf Shield you get from Wood Man, Wood Man is nearly as painful as Air Man, Wood Man's weakness is Atomic Fire from Heat Man, Heat Man's stage has that Yoku Blocks section that needs Item 2 to get through easily. So, unless you can beat Air Man, Wood Man or Heat Man, you will find yourself stuck in a loop. ''Airman Ga Taosenai'' sums up this all. [[TakeAThirdOption Of course, Wood Man is ALSO weak to the Metal Blade...]]
* ThisIsADrill: The Mole enemies that pop up in Metal Man's stage, and later Skull Castle 2.
* ThrowingYourShieldAlwaysWorks: Wood Man's weapon of choice--the shields in question are ''leaves''.
* TimeBomb: Crash Man's weapon.
* TimeStandsStill: Flash Man's power.
* TornadoMove: Air Man fires swarms of miniature tornados at the player, pushing them backwards against the wall in the process.
* TrialAndErrorGameplay: Quick Man's Stage. Wily Stage 4, by virtue of its invisible pits, as well as its Wall Shooter boss, also has this.
* UnderwaterBossBattle: In Bubble Man's stage.
* UpdatedRerelease: The Europe and Japan only 16-bit upgrade included in ''The Wily Wars'' for the SegaGenesis (although it did get a Sega Channel exclusive American release), and ''Rockman 2: Complete Works'' for the PS1 in Japan (this version was later incorporated into the ''Anniversary Collection'').
* {{Unwinnable}}: The Buebeam Trap if your Crash Bomber ammo is not completely full. Also, the final boss is impossible to defeat if you don't have enough Bubble Lead ammo. You aren't ''stuck'' per se, but you'll need to sacrifice some extra lives.
* UtilityWeapon: Crash Bombs are the only thing that can destroy those hard walls.
* VideoGameSettings:
** AbsurdlySpaciousSewer: Heat Man's stage.
** BlackoutBasement: One part of Quick Man's stage becomes this.
** BubblyClouds[=/=]LevelsTakeFlight: Air Man's stage.
** ClockworksArea: Metal Man's stage.
** DownTheDrain: Bubble Man's stage and Wily Stage 3.
** EternalEngine: Metal Man and Quick Man's stages, and the Wily Stages.
** ItsAllUpstairsFromHere: Crash Man and Wily Stage 1.
** IcePalace: Flash Man's stage.
** LethalLavaLand: Heat Man's stage.
** TheLostWoods: Wood Man's stage.
** NoSidepathsNoExplorationNoFreedom: Air Man, Wood Man, Heat Man and Bubble Man's stages.
** UndergroundLevel: The very last part of the game.
** TheVeryDefinitelyFinalDungeon: The underground cavern beneath Skull Castle.
* VillainsWantMercy: Wily in the ending.
* WalkDontSwim: Mega Man can't swim, so he just sinks in Bubble Man's stage. However, unlike the first game, he can jump ''very'' high.
* WeaksauceWeakness:
** The [[spoiler:alien]] can only be harmed by bubble lead. [[Film/{{Signs}} Wait a minute...]]
** Metal Man notably can be killed in one shot ''by his own weapon'' on American difficulty.
* WhenTreesAttack: Wood Man.
* ZergRush: The Tellies in Crash Man's stage and Wily Fortress.
