->"''Ah, the wonders of 6502 assembly hacking. Where most people would prefer making Mega Man fangames in Flash or other similar platforms, there are people such as Puresabre and other Japanese hackers that rework their entire games with extensive reprogramming."''
-->-- '''YouTube comment by [[https://www.youtube.com/watch?v=K2tzMEah-Ic LuwiigiMaster]]'''

''Rockman 4 Minus Infinity'' is a ''[[VideoGame/MegaMan4 Rockman 4]]'' [[GameMod ROM hack]] by a Japanese person who goes by [=PureSabe=].

While [[VideoGame/KaizoMarioWorld other]] [[VideoGame/RockmanNoConstancy ROM hacks]] tend to just make the original game [[PlatformHell harder]] or alter it in a few ways and little else, this one ascends beyond this status to turn the original game into an incredible experience. The staggering amount of new content include new level designs, bosses, features, weapons, music, enemies from other ''VideoGame/{{Mega Man|Classic}}'' titles, {{Shout Out}}s to other video games, and more!

While the game is complete (as of June 2012), it's still being worked on, the latest release being [[http://www.geocities.jp/borokobo/zip/Rock4mi_097.zip 0.97 (made available in August 2014)]].

[[https://sites.google.com/site/rockman4mi This site]] contains lots of information on the game.

----
!!This game provides examples of:
* HundredPercentCompletion: Getting a hero score of 100.
-->'''Proto Man:''' [[spoiler:I have no advice. You are real hero! I hope you will not fight as Megaman anymore. Do you think Dr. Wily give up? No answer needed.]]
* AbnormalAmmo: Spark. Manbow lets Mega Man shoot light bulbs and Rush Cannon lets Mega Man shoot Rush at his foes.
* ActuallyADoombot: Crash Man, Wave Man and the Chimerabots are actually holograms. [[spoiler: As are the BaitAndSwitchBoss and the TrueFinalBoss. Mega Man figures out that they're holograms almost immediately, but that doesn't make them any less dangerous.]]
* AdaptationExpansion: Adds numerous new bosses/mini-bosses, enemies and even more gameplay changes.
* AdvancingBossOfDoom: [[VideoGame/MegaMan7 King Gojulus]] in Skull Man's stage, as well as [[BossInMookClothing Jumbig]] in some stages.
* AdvancingWallOfDoom: In Dust Man's stage, you have to outrun a rather slow ([[RubberBandAI or fast]]) wall.
* AfterBossRecovery: [[spoiler:Super Shadow Man]] drops a [[VideoGame/MegaMan1 Yashichi]] after his death, which refills all your health and weapon energy.
* AllTheWorldsAreAStage: Wily Stage 3.
* AlwaysAccurateAttack: The Wishing Star Adapter. It covers the screen, but you only get one shot.
* AndIMustScream: The description for the Energy Splitter (obtained by [[VideoGameCrueltyPotential sucking up Eddie]]) implies ''Eddie is still alive inside it.''
--> [[FridgeHorror "You seem to hear something in this unit."]]
* AntiFrustrationFeatures: Mega Man starts with three items and Rush Search. In addition, dying three times on [[spoiler:the final EscapeSequence]] causes [[spoiler:the spikes to turn green and only do one damage, in addition to giving you more time]].
** If you lose at Wily Machine's second phase, the first phase will start with a single bar instead of the massive one.
** Once you're hit by Optical Capsule's laser, all lasers that are on screen disappear (he still shots the rest of burst, though), fitting in with the Touhou-like pattern of them. This doesn't happen if Hard Mode is turned on, though.
* ArtificialBrilliance: If you use Rush during the Snatchman battle, he will ''confuse you for the doppelganger.'' Yes, you can end up healing the ''boss'' when you're low on health! To ''really'' rub it in, it ''still uses your weapon energy.''
** AIBreaker: Using Recycle Inhaler to trap Snatchman in an E-Tank, however, works around this. You can use this to OneHitKill the boss with Rush Cannon.
** More brilliance: all the Robot Masters change their patterns to dodge Rush Cannon if you fire it at them. Some even [[HoistByTheirOwnPetard turn it against you!]]
* AuthorAppeal:
** Puresabe seems to be a big fan of ''[[VideoGame/MegaManV Rockman World 5]]'' and ''VideoGame/MegaManX2''. The Cossack bosses are based on the X-Hunters and the Charge Shot looks like the Charge Shot from ''X2''. Some of the enemies and gimmicks from ''Rockman World 5'' show up.
** He also seems to like Shadow Man a lot, as the latter is [[RecurringBoss fought several times]] throughout the game.
* AutoScrollingLevel:
** Sections of Skull Man's level, which has every kind of dynamic platform from the 8-bit Mega Man series.
** Wily Stage 2's last half, which is a {{Homage}} to the ''VideoGame/{{Gradius}}'' series' High Speed Zone stages.
* BackStab: In certain battles, Shadow Man will seemingly leap off-screen before performing this OneHitKill move.
* BaitAndSwitchBoss:
** [[spoiler: The Alien.]]
** Reaching the third Chimerabot in Wily Stage 4 without losing a life for the entire game has [[spoiler:Super Shadow Man]] destroying it [[spoiler:with a DiagonalCut]].
* BalefulPolymorph: Toad Man's [[Franchise/FinalFantasy Toad]] Spell, when used by him, turns you into a defenseless frog from ''[[VideoGame/ForTheFrogTheBellTolls Kaeru no Tame ni Kane wa Naru]]''. When used by you, it turns enemies (and ''items'') into tiny, harmless toads.
* BerserkButton: Pharaoh Man gets upset when Mega Man destroys the statues in his stage and later challenges him to a battle when Mega Man destroys the coffin in his room.
* BewitchedAmphibians: Toad Man's weapon does this to enemies (and powerups!), and during the BossRush it acts as a OneHitKill against Toad Man himself (but you can ''not'' kill him, [[MultipleEndings and he'll show up in the ending still transformed as well]]). Its animation is a ShoutOut to ''VideoGame/FinalFantasyIII''.
* BlackoutBasement: The first half of Bright Man's level. You can see the level in general, but not enemies and objects under or over you.
* BlindedByTheLight: Spark Manbow has a secondary function. If you hold up when you press the fire button, Mega Man holds up a lightbulb and causes a bright flash of light to cover the screen, which makes enemies stand still for a few seconds.
* BlindIdiotTranslation: Although Puresabe did admit his bad English skills in the English readme file. The 0.02 and 0.97 releases lampshade this - the language select option has "Japanese" and "Engrish", with a real English release coming soon.
* BonusBoss:
** Wave Man in Dive Man's Stage and Crash Man in Drill Man's stage. Beat them and unlock the Wire and Balloon Adaptors before the Cossack stages.
** [[spoiler: Super Shadow Man]] in Wily Stage 4 if you get the secret condition.
** Green Helmet, who only appears in [[spoiler:The TRUE Arena]]. This is a composite of all three variants of the Metool EX from the original ''Mega Man 4'' with a full health bar.
** [[spoiler:[[VideoGame/FinalFantasyV Omega]], who makes its only appearance as the final opponent in The TRUE Arena]].
* BottomlessPitRescueService: If you find and rescue Beat in Skull Man's stage and Cossack Castle Stage 1, he does this for you at the cost of some of your HP for the rest of the stage.
* BossInMookClothing: The Jumbig, which takes ''127 Mega Buster shots to kill.'' He also pushes you back if you run into him, so you can't just abuse invincibility frames to bypass him. Oh, and did we mention that he appears at least once in '''every''' level? And on top of that, he gains some additional projectile attacks when you start the fortress levels... On Hard Mode, they ''start'' with their upgrade from the beginning and then starts firing ''[[ExaggeratedTrope one-hit-kill spike balls]]'' in the Wily Castle stages!
* BossRush: While Wily 3 is more of a {{Metroidvania}}, the Mechanical Arena unlocked by beating the game is a straighter version (a homage to the Arena in ''VideoGame/KirbySuperStar'').
* BraggingRightsReward: [[spoiler:The ?Dagger you get by defeating Super Shadow Man. Considering said boss fight occurs at the tail end of the game, and to even ''see'' said boss fight you have to have no lives lost all the way up to that point, ''and'' you have to beat this [[NintendoHard ridiculously hard]] boss in a ''single life'', the only thing obtaining this weapon proves is that you don't need the damn thing. However it helps greatly against the Optical Capsule on Hard, which is a blessing.]]
* BulletHell: Mothraya. [[spoiler:Also Optical Capsule.]] On Hard Mode, ''Quint'' also becomes this.
* CallForward:
** Drill Man's stage has Up'N'Down enemies jumping through the ground, a reference to Ground Man's stage in ''VideoGame/MegaManAndBass''.
** Pharaoh Man's stage contains destroy-able statues, which look the same as the ones in that same stage.
** The Exchanger (which converts life energy into weapon energy if you have full health) is the same item you could buy in ''VideoGame/MegaMan8''.
* ChargedAttack: Mega Buster MI and Pharaoh Shotgun.
* ChestBlaster: Dive Man's Water Cutter.
* CollisionDamage: Played with against Snatchman. If you collide into him, he takes damage too.
* CompositeCharacter: The Chimerabots. The first is a mix of [[VideoGame/MegaMan1 Cut Man and Elec Man]], the second's [[VideoGame/MegaMan2 Quick Man and Wood Man]], and the third and final one is [[VideoGame/MegaMan3 Needle Man and Gemini Man]].
* ContinuityPorn
* ConvectionSchmonvection:
** Pharaoh Man's stage has two sections where Mega Man can be near the lava but gets damaged if he gets in it.
** Averted in a section of Dust Man's level. Mega Man gets a temperature gauge that fills up slowly. If it reaches the top, Mega Man takes damage.
* CoresAndTurretsBoss: The Serges Devil.
* CreditsMedley: PlayedWith - the credits theme is a medley of three credits themes from the ''VideoGame/{{Kirby}}'' series, specifically ''[[VideoGame/KirbySuperStar Super Star]]'', ''Block Ball'', and ''Dream Course''.
* CriticalHit: Happens on occasion. Get the Super Star from any Shadow Man encounter by finishing him off with a Recycle Inhaler, and the chances of this increases. [[spoiler:His final appearance drops the ?Dagger, which makes ''every'' hit critical.]]
* DamselInDistress: Mega Man has to break Kalinka out of a cage (guarded by [[spoiler:a Copy Roll]], of all things), in order to advance in Wily Castle stage 3.
* DeadCharacterWalking: A variation - if you die while using Hell Wheel, the wheel keeps going (along with the camera). In some points you can even get to the next ''screen'' this way (though you obviously can't do anything)!
* DemotedToExtra: Rush Marine only makes a cameo during a transitional point in Dive Man's stage. Rush Coil, meanwhile, makes no appearance at all.
* DescendingCeiling: Drill Man crashes the ceiling in his arena as his OneHitKill DesperationAttack.
* DetachmentCombat: Square Machine.
* TheDevTeamThinksOfEverything:
** The credits (which feature ''Franchise/FireEmblem''-like stats for the Robot Masters) also record the weapon you killed them with.
** Mega Man has a unique sprite for standing on ledges.
** In Pharaoh Man's stage, the "Reverse" Curse is pretty straightforward, it reverses all your controls, even going so far as to remap the menu to Select instead of Start.
** In the fight with Pharaoh Man, he starts destroying the pyramid you're in. If you revisit the stage after beating him, the damage is still there.
** All the Robot Masters change their patterns to avoid Rush Cannon if you fire it. Some actually [[HoistByTheirOwnPetard find ways to kill you with it.]]
** If you die to the final boss [[spoiler:(which is extremely difficult, due to the [[EleventhHourSuperpower Wily Buster]] reducing all damage to one)]], you respawn outside the boss door - [[spoiler:only you keep the Wily Buster and the room is shown as it really is, rather than the WombLevel facade it had when you first enter]].
* DiagonalCut: [[spoiler:This is how Super Shadow Man kills the third Chimerabot in Wily Stage 4.]]
* DifficultyLevels: As of v0.02, difficulty options are added -- "Normal"[[note]]MAIN: Norm; DAMAGE: x1.0; CRITICAL: On; ITEM DROP: Norm; FAIL-SAFE: Norm; E.GEN.: On[[/note]], "Easy"[[note]]MAIN: Norm; DAMAGE: x0.5; CRITICAL: On; ITEM DROP: More; FAIL-SAFE: Safe; E.GEN.: On[[/note]], "Hard"[[note]]MAIN: Hard; DAMAGE: x1.5; CRITICAL: On; ITEM DROP: None; FAIL-SAFE: Norm; E.GEN.: Off[[/note]], and "Stable"[[note]]MAIN: Norm; DAMAGE: x1.0; CRITICAL: Off; ITEM DROP: None; FAIL-SAFE: Norm; E.GEN.: On[[/note]]
* DopplegangerAttack: Chimerabot #3.
* DownInTheDumps: Dust Man's stage.
* DownTheDrain:
** Toad Man's level.
** Cossack Castle Stage 3, which has water with differing physics.
* DualBoss:
** Rong Rong Rong, Rang Rang Rang, and Rung Rung Rung in Ring Man's stage.
** The Nightmare Suzy Minibosses in Cossack Castle Stage 4.
** The third Chimerabot (a fusion of [[VideoGame/MegaMan3 Gemini Man and Needle Man]]) in Wily Stage 4.
* EndGameResultsScreen: The game calculates your "hero score" based on a number of factors (i.e. if you rescued Rush and Beat or sucked up Eddie with the Recycle Inhaler, or getting all the secret items), with Proto Man giving a comment based on what you did wrong (if you ''did'' anything wrong).
* EvilKnockoff: Snatchman in Wily Stage 2. If you beat him once, he steals 4 of your Robot Master Weapons with the help of Dr. Wily's Stealing System.
* FeedItWithFire: Dust Man, with anything except Toad Spell when he is using Recycle Inhaler.
* FlechetteStorm: [[spoiler: Super Shadow Man does.]]
* FrogsAndToads: Most of the enemies in Toad Man's stage.
* GameplayAndStorySegregation:
** In at least two cutscenes near the end of the game, Mega Man fires a charged shot without having to charge up first, the first time happening when [[spoiler:he destroys Kalinka's cell]] and the second time happening when [[spoiler:he shoots down the alien cave projector]].
** The Wish Star adaptor uses up its entire energy bar when used, even after [[spoiler:rescuing Kalinka in Wily Stage 3 and she attaches a device to Rush that halves the usage costs of the Rush Search and Rush Cannon adaptors]]. Even if the player uses the Wish Star adaptor to defeat [[spoiler:the Wily Machine]], Mega Man is still able to immediately use it again afterwards [[spoiler:to destroy Wily's escape pod]].
* GenreSavvy: Like in ''VideoGame/MegaMan4'', [[VillainExitStageLeft Dr. Wily leaves in an escape pod after destroying the Wily Machine]]. [[spoiler:Unlike that game, however, Mega Man immediately uses Wishing Star and destroys Wily's pod.]]
** DangerouslyGenreSavvy: [[spoiler: Wily triggers the usual SelfDestructMechanism at the end, but he also has an anti-teleportation field preventing Mega Man from just beaming out. Instead, he has to escape the CollapsingLair on foot (or rather on the Hell Wheel).]]
* GimmickLevel: Lots of them.
** Skull Man's stage has pretty much every moving platform from the NES games.
** Ring Man uses a {{nerf}}ed version of Quick Man's [[FrickinLaserBeams laser beams]] [[DoomyDoomsOfDoom of doom]].
** Bright Man has two: the first half of the stage is [[BlackoutBasement only lit on your X-axis position]], while the second half uses red, blue and green [[TemporaryPlatform disappearing blocks]], which damage you should you be in them when they appear. There are also ladders and SpikesOfDoom that function in this manner.
** Pharaoh Man's stage contains the curses that do various things to you depending on where you're at in the pyramid. Oh, and the boss fights against him involve these curses too.
* GoForTheEye: The Aqua Devil in Cossack Stage 3.
* GrapplingHookPistol: Wire Adapter.
* HappyDance: Mega Man does one when he [[spoiler:defeats Omega in The TRUE Arena]].
* HighAltitudeBattle: Mega Man ends up in one against Mothraya while riding Rush.
* HitboxDissonance: Optical Capsule's lasers have rather weird hitbox and can pass through you without damaging you.
* HoistByHisOwnPetard:
** Toad Spell turns the debris Dust Man expels out of his ArmCannon into toads. When he inhales it back in, he gets damaged instead.
** Toad Man, in a homage to Mega Man 2, gets killed in one hit if you use Toad Spell on him. Probably because the Toad Spell cures the Toad status in the ''FinalFantasy'' games.
** Spark Manbow affects Bright Man just as much when he uses it against Mega Man.
** Dust Man and Bright Man can do this to ''the player'', should they try to use Rush Cannon on them. The former inhales it and fires it back at you, while the latter [[TimeStandsStill freezes time]] and knocks you into the path of your own weapon.
* {{Hologram}}: Crash Man and Wave Man. [[spoiler:The alien lair, as well as the Petit Robot Masters.]]
* HorseOfADifferentColor: In a homage to the ''Mega Man Power Battle/Fighters'' series, Shadow Man rides on a giant toad in Toad Man's stage.
* HPToOne: Shock Guard Upgrade turns the spikes into these.
* IFellForHours: After beating Mothraya and Square Machine.
* InfinityMinusOneSword: Not trying to be punny with the game name, this game has a lot of InfinityMinusOneSword Weapons you can get from the Robot Masters that make Metal Blade look nerfed.
** Hell Wheel can steamroll through enemies that aren't Jumbig.
** Homing Control Ring Boomerang can stay hold on enemies and stick there to do massive damage. This is probably the easiest way to kill a Jumbig.
** Pharaoh Shotgun can fire out FIVE Pharaoh Shots at once.
** Water Cutter is basically an ''even more'' broken version of Metal Blade.
* InfinityPlusOneSword: [[spoiler:The ?Dagger, which you must reach Wily 4 and fight [[ThatOneBoss Super Shadow Man]] in ''one life'' (dying invalidates the condition and skips him) to obtain. It turns ''every'' hit into a CriticalHit, making the rest of the game a breeze.]]
* ISurrenderSuckers: Dr. Wily, of course. In this case, he even [[spoiler: tricks Mega Man ''into [[LookBehindYou looking in another direction]]'' before making his getaway]].
* InconsistentDub: The English language setting uses the appropriate {{Dub Name Change}}s, though there are some inconsistencies:
** In the cutscene after defeating Dr. Cossack, when Mega Man goes after Dr. Wily, his name is initialised as "R" (for Rockman).
** Dr. Light is called "Dr. Right" in the intro to the third Wily Stage.
** When Mega Man first speaks to Kalinka upon rescuing her in the third Wily Stage, his name is again initialised as "R" (for Rockman).
** [[spoiler:If Proto Man comes to give Mega Man the [[EleventhHourSuperpower Wily Buster]] during the final battle, his name is displayed as "Blues".]]
* InconvenientlyPlacedConveyorBelt: Dust Man's stage and Wily Stage 2.
* InterfaceScrew: Pharoah Man's stage has a curse and if Mega Man is inside the pyramid, he will be affected by it.
* KaizoTrap: ''You'' can do this to Robot Masters. It's possible to get a last shot which hits after your death, and finish off Robot Master (the game behaves as if you lost, though); this also shows the fact that there can't be more than one death explosion on screen. The easiest weapon to pull it with is Toad spell, as it doesn't damage instantly.
* KilledOffForReal: When Shadow Man gets a DisneyVillainDeath in Cossack Stage 1, you can hear him exploding.
* KingMook: Joe Ni-Nin Va All in Wily Stage 1.
* {{Knockback}}: Normally averted, though the Jumbig can send you ''flying across the screen''. It can send you flying into the ''next'' screen in Toad Man's level!
* LaserHallway: Ring Man's stage.
* LastChanceHitPoint: The Skull Amulet has this effect, as of the v.00.1 release.
* LethalLavaLand: The second half of Pharaoh Man's level.
* LivingStatue: The Fire Man, Heat Man and Flame Man statues near the end of Pharaoh Man's stage.
* LongName: Holdable Control Ring Boomerang. Shortened to "HCR Boomerang" in the "You Got..." screen.
* MarathonLevel: Wily Stage 3, which is unfortunate since it's also a maze.
* MakeMyMonsterGrow: [[spoiler:Inverted by the Petit Robot Masters]].
* TheMaze: Wily Stage 3, known as Wily's Labyrinth.
* MercyInvincibility: Its duration is ''greatly'' reduced. [[spoiler:Super Shadow Man's attacks don't trigger it, which makes fight that harder.]]
* {{Metroidvania}}: Wily Stage 3.
* MiniBoss:
** Shadow Man in Toad Man, Bright Man, and Pharaoh Man's stages, as well as Cossack Castle Stage 1.
** Whopper and Rong Rong Rong, Rang Rang Rang, and Rung Rung Rung in Ring Man's stage, which is a homage to Lololo and Lalala from the ''{{Kirby}}'' game series.
** Hogale and Enker in Dive Man's stage.
** Quint and Kabatoncue in Drill Man's stage.
** King Gajuras in Skull Man's stage.
** Giant/Nightmare Suzy, Terra, Ballade, and Punk in Cossack Castle 4. They guard the generators powering the barrier leading to Dr. Cossack.
** Gamarn and Gamadayu in Toad Man's stage.
* MultiMookMelee: The first half of Wily Stage 2. [[spoiler:The TRUE Arena]] has three of these in the form of "Wily's Army", "Wily's Navy", and "Wily's Airforce".
* MultipleEndings: The ending of the game has several permutations depending on your actions:
** If you rescue Rush during the final level, [[spoiler:Mega Man will use Rush Cannon on Wily's space ship upon escaping the castle]]. Otherwise, [[spoiler:Mega Man will collide with the space ship instead, destroying it regardless]].
** Eddie, Rush, and Beat make appearances depending on if you used the Recycle Inhaler on the former and/or rescued the other two during the final level.
** If you turned Toad Man into a toad during the rematch and spared him, he will appear in the first part of the credits, hopping alongside the train.
** If you [[spoiler:get the ?Dagger]], [[spoiler:Shadow Man will be seen on his kite in the background in the first part of the credits]].
** Depending on what happened to Rush, Eddie, and Beat at the end of the game, they will appear either in color or grey in the "Presented by Capcom" screen.
* MultipleLifeBars: The final bosses, in paticular.
** The Wily Machine's first phase has [[spoiler:one full health bar, where each hit point represents its own separate health bar. That adds up to 29 times 28, or '''812 hit points''']].
*** [[spoiler:Fortunately, in [[BossRush The Mechanical Arena]], it only has 224 hit points.]]
** The Optical Capsule later on has [[spoiler:two health bars, giving it 56 hit points]].
** And then [[spoiler:the Petit Robot Masters, who each has his own lifebar, with the one last hit's currently shown. That adds up to 8 times 28, or 224 hit points]].
** [[spoiler:Super Shadow Man two life bars, with about 112 hit points]].
* MutuallyExclusivePowerups: Drill Man and Dive Man's stages have Mega Man temporarily get the [[VideoGame/MegaManII Sakugarne]] and [[VideoGame/MegaManDrWilysRevenge Mirror Buster]] respectfully. You won't be able to use the other weapons while you use them. Meanwhile, in the final Dr. Cossack stage, the [[VideoGame/MegaManIII Screw Crusher]], [[VideoGame/MegaManIV Ballade Cracker]], and [[VideoGame/MegaManV Spark Chaser]] replace the Mega Buster for the rest of the stage, but collecting them is optional.
* MyGodWhatHaveIDone: Beating the game after sucking up Eddie has Proto Man lamenting his loss in the EndGameResultsScreen, then noting "Are you trembling?" This leads to a YouBastard moment when he notices that he disappeared near Mega Man, and thus you saw his demise ([[DramaticIrony not knowing YOU were the one that caused it]]).
* MythologyGag: There are a ''whole'' lot of enemies from other Mega Man games, for starters.
** The lifebars/HUD from the Game Boy ''VideoGame/MegaManClassic'' games (also known as the ''Rockman World'' series) show up for the first half of Bright Man's stage. They also appear when fighting [[spoiler:the Optical Capsule]] and [[spoiler:the Petit Robot Masters]].
** Holdable Control Ring Boomerang gains the PowerUpMagnet abilities of its Game Boy version.
** Drill Man's stage contains Ring Man's hippo MiniBoss, which has the blocks of its Game Boy counterpart.
*** Pluto's MiniBoss also appears, and Drill Man himself copies Uranus' DesperationAttack of crashing the ceiling down on you.
** Pharaoh Man and Drill Man's stages also contain falling blocks from the fourth Game Boy game.
*** ''And'' [[LivingStatue Living Statues]] of Fire Man, Heat Man, and Flame Man show up at the very end of the former.
** An enemy from Aqua Man's stage in ''VideoGame/MegaMan8'' appears in Dive Man's stage here.
** The Balloon Adapter is based on the Rush Jet Adapter from ''VideoGame/MegaMan3''.
** The manner in which the Chimerabots are set up is similar to that of the Doc Robots from Mega Man 3, complete with the beginning of Mega Man 3's boss theme playing.
** The tokens dropped by the Robot Masters in Wily Stage 3 are taken from Mega Man 1. They are replaced by Yashichis whenever their rooms are revisited.
** When Crash Man and Wave Man's holograms are defeated, the device used to operate them appears. It's the exact same projector Dr. Wily used for his alien form in ''VideoGame/MegaMan2'''s final battle.
** Skull Man's stage has ''[[UpToEleven every moving platform from the first six games.]]''
* NamesToRunAwayFromReallyFast; Jumbig the Death Machine. [[BossInMookClothing How fitting.]]
* {{Ninja}}: Shadow Man.
* NintendoHard
* [[NoDamageRun No Lives Lost Run]]: Required to fight [[spoiler:Super Shadow Man]] in Wily Stage 4.
* NonLethalBottomlessPits: The Trampoline Upgrade turns every {{bottomless pit|s}} into these.
* NotHisSled: Three bosses from the original game -- Cockroach Twins, [[KingMook Metool Daddy]], and Tako Trash -- are replaced with new bosses. [[spoiler: Averted for the Cockroach Twins in the TRUE Area in the form of Omega. Nope, not the [[VideoGame/MegaManZero Messiah of Weil]], but the dreaded enemy from ''VideoGame/FinalFantasyV'' in all of his glory.]]
* OhCrap: [[spoiler:Shadow Man gets this reaction after defeating him as Super Shadow Man when his smoke bomb that he used to cover his escape every other time fails to go off. To rub salt into the wound, it then ''does'' go off moments after he explodes]].
* OneBulletAtATime: The Minimum curse in Pharaoh Man's stage.
* OneHitKill:
** The Rush Cannon Adaptor. However, a few of the Bosses can turn it against you.
** If Dust Man sucks you up, he turns you into an E-Tank. If you don't break free, he kicks you into the incinerator.
** Shadow Man in Pharaoh Man's stage has one.
** Cast the Toad spell on Toad Man during the BossRush. He turns into a easily-squished toad.
** Use Spark Manbow's secondary ability on Bright Man to freeze him in place, and then fire a lightbulb at him. The explosion should kill him in one hit.
** Shadow Man can do this. If you run into him during some of the battles against him, he'll most likely grab you, pull out a shuriken, and ''slice you in half with it.'' [[spoiler:And he ''will'' do this as Super Shadow Man if don't react quickly enough.]]
** [[spoiler:Omega's signature killing moves from ''VideoGame/FinalFantasyV''. Some don't kill you, but remove you from the battle through, which also counts as having lost.]]
* OneHitPointWonder: The configuration menu in the 0.02 release allows you to play the game with only 1 hit point in Mega Man's life meter.
* OneHitPolykill: Drill Torpedo and Water Cutter.
* PainfullySlowProjectile: The Minimum curse inflicts this on you in Pharaoh Man's stage. Combined with OneBulletAtATime above, it ''really'' starts getting annoying.
* PoisonMushroom: The Skull Amulet [[http://www.youtube.com/watch?v=iV6xsgUseeM originally]] made Hell Wheel ''really'' slow. Then the 0.01 release subverted it.
* PowerUpMagnet: Holdable Control Ring Boomerang can snatch items as a {{homage}} to ''VideoGame/MegaManIV'' on the Game Boy.
* RatchetScrolling: [[spoiler:In the final escape sequence.]]
* RealTimeWeaponChange: Using the A and B buttons on the second controller, you can change Mega Man's weapons.
* RecurringBoss: Shadow Man.
* RecurringExtra: Up'n'Down
* ReferenceOverdosed
* ReverseShrapnel: Hell Wheel.
* RibcageRidge: Skull Man's stage.
* RingsOfDeath: Ring Man and Holdable Control Ring Boomerang.
* RubberBandAI: The AdvancingWallOfDoom in Dust Man's stage.
* SelfDestructMechanism: [[spoiler:The last part of the whole game.]]
* SequentialBoss: Pharaoh Man (first time), Square Machine, Aqua Devil, Joe Ni-Nin Va All and Snatchman.
* ShockAndAwe: Bright Man
* ShoutOut: See [[ShoutOut/Rockman4MinusInfinity this page]].
* SmokeOut: Shadow Man always does this after beating him in a Robot Master stage to hide his method of escape.
* SongsInTheKeyOfPanic: When fighting the main 8 Robot Masters, the music speeds up when they enter their [[TurnsRed Pinch]] mode.
* SpreadShot: Pharaoh Shotgun shoots in five different directions.
** Drill Torpedo fires three drills; one straight ahead, one on the ceiling, and one on the floor.
* SprintShoes: Hell Wheel.
* SuspiciousVideoGameGenerosity: Extra life and E-Tank drops are extremely common in this game. The final levels of the game give you ''lots'' of health and ammo. It's even the page image!
* ThisIsADrill: Drill Man and Drill Torpedo.
* TimedMission: [[spoiler:The escape sequence gives the player one minute to escape the self destructing Wily Castle.]]
* TimeStandsStill: If you hold up when you use the Spark. Manbow, all the enemies on the screen except a few get frozen for a few seconds.
* TookALevelInBadass:
** Toad Man and Dust Man, compared to the original game, are much more of a threat.
** Also, [[spoiler:Shadow Man.]] The "final" fight against him is pathetically easy, [[spoiler:but his "Super Shadow Man" appearance is ''much'' tougher.]]
** Many of the game's [[MiniBoss Mini-Bosses]] become this in Hard Mode; for example, Quint's Sakugarne now creates an earthquake when he hops on and lands with it, which ''hurts'' Mega Man if he's on the ground, and this same earthquake also causes a [[CollapsingCeilingBoss ton of rocks to drop from the ceiling]], '''''and''''' the rocks it previously dug up before are now thrown ''much'' further across the room. To put it bluntly, a once pathetically easy [[AntiClimaxBoss Anti-Climax]] MiniBoss is now a ridiculously brutal BulletHell MiniBoss.
* TrueFinalBoss: [[spoiler:Of the TRUE Arena it is [[VideoGame/FinalFantasyV Omega]] with everything you know]].
* TurnsRed: All of the Cossack Robot Masters have a more aggressive "Pinch" mode that activates when they reach critical health, complete with pallete change and [[SongsInTheKeyOfPanic faster music]], with Pharaoh Man notably taking this to [[UpToEleven extreme]] [[SequentialBoss lengths]]. [[spoiler:When you refight them in Wily Stage 3, they are already in their Pinch mode behaviour, but retain their original palletes and music.]]
* UnderwaterBase: The second half of Dive Man's base.
* UnderwaterBossBattle: Dive Man
* UnexpectedShmupLevel: Cossack Stage 1's second half, which has you ride on the Balloon Adaptor until Shadow Man ambushes you. After the MiniBoss battle, you do some SkySurfing with Rush.
* UnexplainedRecovery: [[spoiler: Shadow Man shows up and kills Chimerabot #3 to become the boss in that section if you get the secret condition, even though he died in Cossack Castle stage]].
* UnlockableContent: [[spoiler:As of version 0.02, clearing the game unlocks a [[TimeTrial Time Attack]] mode which allows you to {{Speedrun}} individual levels, an [[SoundTest Audio Player]], and [[BossRush The Mechanical Arena]]. Clearing the latter unlocks Limited Arena where you're limited to either the Mega Buster or one of the eight weapons retrospectively (the game's merciful enough to give you some E-Tanks and restore health between fights). Clearing one of them unlocks My Arena in which you can ''customise its settings'', and an Extra Configuration menu which practically allows you to ''edit your save file'' [[note]]although this function is dangerous; it even warns you to make a ''save state'' before trying to mess around with it[[/note]]]].
** [[spoiler:Giving yourself Sakugarne reveals that it either one-shots ''everything'', including bosses, or skips it to next phase/pattern if it isn't the last one; though it can glitch out the bosses, or even drop them items. You can even kill Eddie, and destroy Drill Man's ground (which can lead you later into [[KaizoTrap double KO]]) or the moving platforms that appear during one of the Cossack boss fights. It also collides with something that doesn't make sense, like bullets or weapon energy tanks. Mirror Buster, on other hand, glitches out bosses instantly. Also, both run on ''bosses'' HP bar, which provides hilarious and weird effect if entered the room with the item on.]]
* VictoryFakeout: [[spoiler:Did you think the game was over when you defeated the Optical Capsule?]]
* VideoGameCaringPotential:
** In the rematch against Toad Man, you can turn him into a toad then spare him by not squishing him. He (as a toad) appears in the credits if you do this, and you get points added to your score.
* VideoGameCrueltyPotential:
** Use Recycle Inhaler on Eddie and he turns into a Energy Splitter. However, [[VideoGameCrueltyPunishment do that]] and Eddie won't give you any warnings for Cossack Stage 1 and Wily Stage 2 or show up to give you any powerups in the other stages. Proto Man will even lament his loss in the post-credits results screen.
-->'''Proto Man:''' Your rookie ... Eddy. It's regrettable about him. I've never expected that his core have not found in the ruin of Wily's [[JapaneseRanguage fortless]]. ...! Are you trembling? I see... as I heard that his signal disappeared near you, you saw his last moment... didn't you? Don't mind, you had done best effort to him.
** A lesser example can be done, in Dive Man's stage; the Up'N'Down enemy wears a scuba diving mask for its appearance there, but if you shoot it off, it will drown and explode.
* VillainExitStageLeft: Shadow Man, until he dies via DisneyVillainDeath. Quint escapes after he is defeated and never returns.
* WallJump: Toad Man
* WeaponsThatSuck: Dust Man and Recycle Inhaler. Recycle Inhaler acts like Kirby's inhale ability and it turns enemies into power-ups.
* WhereItAllBegan: You fight Pharaoh Man in the very first room/screen of his level.
* WolfpackBoss: [[spoiler:The [[YourPrincessIsInAnotherCastle final]], [[DiscOneFinalBoss final]], ''[[VictoryFakeout final]]'' boss has you fighting mini versions of all 8 Robot Masters all at once. Oh, and you've [[OhCrap lost all your weapons and E-Tanks]], so have fun.]]
** EleventhHourSuperpower: [[spoiler:However, if you find yourself losing said final battle, Proto Man comes in to give you the Wily Buster and refill all your health. The Wily Buster shoots charged shots instantly and reduces all damage taken from the Petit Robot Masters.]]
* WombLevel: [[spoiler:The area after Optical Capsule definitely invokes this feeling. As expected, it turns out to be an illusion.]]
* WordSaladTitle
* WrapAround: There is a vertical example in a section of Toad Man's level, as a {{homage}} to [[VideoGame/SonicTheHedgehog1 Labyrinth Zone.]]
* WrittenSoundEffect: The credits track your deaths under "tiwns", which is supposed to be onomatopoeia for Mega Man's death sound.
* YouBastard: Sucking up Eddie leaves Proto Man lamenting his demise in the EndGameResultsScreen, then noticing something:
--> "I see... as I heard that his signal disappeared near you, you saw his last moment... didn't you?"
