History VideoGame / MegaMan8BitDeathmatch

** The Chapter 13 credits have [[spoiler:the player character drifting through space, at which point their HolographicDisguise dissipates to reveal Maestro]].

** The events of ''Mega Man 8'' have a much greater lasting effect: [[spoiler:Dr. Wily uses Evil Energy to create Roboenza, something hinted at as early as the ''Wily Tower'' chapter before becoming a major plot point in both the ''9'' and ''10'' chapters, and not only does Duo's immunity to Evil Energy protect him from Roboenza as well, but the player, having used the Duo Fist at the end of the ''8'' chapter, also quickly becomes immune. On top of ''all of this'', the [[AdaptationalLateAppearane delayed debut of the Stardroids]] allows the Evil Robot to [[HijackedbyGanon take center stage again]] late in the ''VideoGame/MegaManV'' chapter.]]

* DramaticIrony: The plot of the ''Mega Man 10'' chapter hinges around Dr. Light sending the player character after Dr. Wily, who presumably has a cure for Roboenza. However, as the intro for the chapter (and the trailer for V6) make clear, Wily ''does not'' have a cure, as he didn't plan for his own robots getting infected.

* GuideDangIt: [[spoiler:The Weapon Collection sidequest, available after reaching Chapter 13. Every weapon from ''[=MM1=]'' all the way to ''[=MM10=]'' can be bought in Auto's shop, while the ''[=MMV=]'' arsenal and the Mega Man Killers' signature weapons can be gradually collected upon progressing further through the chapter. However, in order to get Dawn Breaker (which can't be used outside this chapter), you have to buy Rush Search and uncover 8 artifacts scattered across the entire game, solve the puzzles inside Lanfront Ruins and defeat Ra Thor along with Ra Devil. Even if you managed to do ''all of the above'', you still have to find Mega Ball and Sakugarne - the only weapons that will be left at this point... all in order to get the trophy.]]

** [[spoiler:In order to ensure Sunstar's resurrection, the eight remaining Stardroids (thanks to Mars) willingly let themselves be infected with Roboenza in one final attempt to stop the player and Dr. Wily. Sure enough, during the fight proper, they are all affected by the various Roboenza effects encountered in the ''Mega Man 10'' chapter]].

* GuideDangIt: [[spoiler:The Weapon Collection sidequest, available after reaching Chapter 13. Every weapon from ''[=MM1=]'' all the way to ''[=MM10=]'' can be bought in Auto's shop, while ''[=MMV=]'' arsenal and Mega Man Killers' signature weapons can be gradually collected upon progressing further through the chapter.

Even if you managed to do ''all of the above'', you still have to find Mega Ball and Sakugarne - the only weapons that will be left at this point... all in order to get the trophy.]]

* SaveTheVillain: At the end of the ''Mega Man 10'' chapter, Dr. Wily agrees to help bring an end to his Roboenza plot, but then Terra appears, seeking Wily's assets for his own purpose. He then kidnaps Wily, and Chapter 13 is dedicated to the player on a mission to stop the Stardroids and rescue Wily.

* RealityEnsues: Yes, Dr. Cossack was forced into villainy, but the fact remains that his robots were the ones causing havoc. [[spoiler:As a result, he was forced to work for the Russian government's space program seemingly for the rest of his life, thus abandoning his creations (outside of a few discreet occasions). It's only after he and his robots help save the world in the finale of the ''Mega Man V'' chapter when he gets a full pardon from the government.]]
** When [[spoiler: King gives his war funds for the robot revolution to Dr. Light to be distributed to those affected by the war]], [[spoiler: Magic Man]] lost their funding, and thus is reduced to [[spoiler: performing as a street magician. Though they're still fairly upbeat about "showing wonders to the world".]]

** A cutscene during the FinalBoss features the line [[spoiler:"Are you more than a machine?" This is a reference to ''VideoGame/MegaMan7'', where Mega Man proclaims he's "more than a robot" before threatening to kill Dr. Wily; in this context though it's very unambiguously heroic, used to encourage Maestro to continue fighting before granting them an EleventhHourSuperpower]].

* AchievementMockery: Carrying over from Zandronium is the Medals system, of which there are three that are considered negative: "You Fail It", "Your Skill is Not Enough", and "Llama". The first two are awarded for a five and ten deaths in a row without scoring a single kill, and Llama is given by fragging a player in the middle of typing a message or using the menu/consoles, or when they're lagging. You can also get the Llama medal from a bot if you're quick enough.

** The first half of the story is a WhatIf scenario taking place immediately after ''Mega Man 6'', exploring what might have happened if Mr. X had been ''a real person'' instead of a [[HijackedByGanon disguised Wily]] — in this case, a more proper TournamentArc that was more than just the sixth game's backstory.[[note]]Interestingly, [[ComicBook/MegaMan the comic book adaptation]] made Dr. Wily and Mr. X into separate people as well...[[/note]] It was a simple ExcusePlot in previous ''[=MM8BDM=]'' versions, but was redone into a proper storyline from Version 5B onwards to bring things in line with later story chapters, which are also fleshed out considerably.

* EveryoneCallsHimBarkeep: [[spoiler:The "Evil (Energy) Robot".]] Out of necessity on the developer's part, as there is NoNameGiven to him in ''Mega Man 8'', nor was he ever given an official name by Capcom. It wasn't until ''[[ComicBook/MegaMan Archie Comics' Mega Man]]'' that he was [[NamedByTheAdaptation given the name]] "[[spoiler:Trio]]", years after [=MM8BDM=]'s ''Mega Man 8'' chapter was finished. He's never referred to by name even in chapters added after he received a semi-official name, likely to be consistent with earlier appearances.

** In ''VideoGame/MegaManII'' the Sakugarne is infamously weak, dealing little damage, being awkward to use, and will hurt its user if he lands on an enemy that isn't killed by the attack. No longer the case in ''8-bit Deathmatch'': the Sakugarne is outright '''terrifying''' in the right hands, dealing significant explosive damage to anyone near it with each landing and outright {{One Hit KO}}ing anything it directly lands on. It's still unwieldy, but that's the trade-off for being so powerful.

* {{Retcon}}: The [[Videogame/MegaManII Sakugarne]] and [[Videogame/MegaManV Spark Chaser]] are given new weapon color palettes as original artwork of Mega Man using the two weapons showed no color change from the base Mega Buster. Sakugarne gives the user a color palette reminiscent of Quint's own, and Spark Chaser applies a blue and lime green colorization.

* RunOrDie: Once you defeat [[spoiler:Sunstar and he gets possessed by the Evil Robot's remains, none of your attacks will work and you will eventually be forced to flee the room and escape the collasping Wily Star]].

* DummiedOut: Campaign data for botmatches on certain absent maps exist; while most (such as [=MM1DW2=] and the later three ''Mega Man 7'' castle stages) ''were'' part of the campaign in early versions, three maps ([=MM2DW3=], [=MMBDW1=], and [=MM9DW2=]) have botmatch data despite never having been part of Single Player.

* NotSoDifferent: If you talk to [[spoiler: Skull Man]] during the {{Playable Epilogue}}, they accuse you of enjoying the thrill of battle just as much as they do.

It takes place after ''VideoGame/MegaMan6'', when the ''real'' Mr. X[[note]]distinguished from Wily's portrayal of him in [=MM6=] by the lack of sunglasses, flat eyebrows, and no dot on his forehead[[/note]] hosts the second annual Robot Master tournament. With Dr. Light's consent, all robots entering must be refitted with Mega Man's powers, to ensure fair competition. However, Dr. Wily sees this as a brilliant opportunity to prove his genius, and enters all of his robots in the tournament. Mega Man, not trusting Dr. Wily in the tournament, decides to enter, but since he can't watch over every match, Dr. Light enters his robots as well. The PlayerCharacter, [[TheGenericGuy a generic robot]] by the name of Maestro[[note]]though it can be given [[HelloInsertNameHere any name you prefer]][[/note]], agrees to work with Dr. Light and investigate Dr. Wily's activities in the tournament.

*** There's an EasterEgg in Mars's map that plays a chiptune cover of music from ''Doom''.

* ColourCodedForYourConvenience: The players change colour to match what weapon they're currently using. In team-based game modes, the players are coloured to match what side they're on instead.

* CutscenePowerToTheMax: Averted by Terra. That omnidirectional simultaneous {{Beam Spam}} setup that he used [[spoiler: to destroy Duo?]] He ''will'' use it against you once things start looking dicey, so be ready to jump.

** [[spoiler:On the final Wily Star stage before facing Sunstar, Wily allies up with the player once more to wipe out the Roboenza-infected Stardroids after they kidnapped him and forced him to build the Wily Star for their own goals. Once he's back on Earth with Dr. Light and Dr. Cossack, he rallies up all of his Robot Masters to create Gamma 2.0 to help the player stop Eclipse]].

* RunOrDie: Once you defeat [[spoiler:Sunstar and he gets possessed by the Evil Robot's remains, none of your attacks will work and you will eventually be forced to flee the room and escape the clasping Wily Star]].

* AdaptationalVillainy: Downplayed. The Stardroids were always a villainous group of robots reprogrammed by Dr. Wily in ''Megaman V'' to take over the world, but in here he has had no hand in their programming; here they become an OmnicidalManiac cult hell bent on awakening Sunstar and infusing him with the power of the Evil Robot to ''destroy'' the world, essentially making them more like their versions from the Archie Comics and ''Gigamix''. Out of all of them, Terra is the most psychotic.

* EveryoneCallsHimBarkeep: [[spoiler:The "Evil (Energy) Robot".]] Out of necessity on the developer's part, as there is NoNameGiven to him in ''Mega Man 8'', nor was he ever given an official name by Capcom. It wasn't until ''[[ComicBook/MegaMan Archie Comics' Mega Man]]'' that he was [[NamedByTheAdaptation given the name "Trio"]], years after [=MM8BDM=]'s ''Mega Man 8'' chapter was finished. [[spoiler:They still don't call him anything else in Chapter 13, likely to maintain consistency with the information established in prior chapters.]]

* ChekovsGun: One of the first things you'll see when starting the game (except when starting it for the first time, since that'll place you in front of Dr. Light, and [[spoiler: in Chapter 13, as you'll be aboard Dr. Cossack's spaceship]]) is [[spoiler: Auto's truck]]. The object in question ends up being of vital importance, [[spoiler: being the "arena" you fight on while being [[ChaseFight chased by Fake Men]]]].

** In a heroic example, [[spoiler: Dr. Wily]] will use whatever weapon the player has equipped ([[spoiler: unless that weapon is Dawn Breaker, in which case they will use your most recently equipped weapon]]) when they team up with you [[spoiler: while fighting the Stardroids in the fourth Wily Star stage.]]

!!The game provides examples of:

[[folder: Tropes relating to the vanilla game and campaign]]

[[/folder]]
[[folder: Tropes relating to Game Mods]]
* ActuallyADoombot: In ''Classes-Based Modification'' (aka YD Classes), the Dr. Wily class turns out to be a robotic fake every time he's killed, much like his initial defeat in ''VideoGame/MegaMan3''.
* BaitAndSwitchBoss: In ''Unholy Bosses'', Abe Penny makes his entrance by instantly destroying the current boss (or in the case of a DualBoss, a random boss) and replacing them in battle. In Version 7, potentially any boss can do this to another. Not even [[DidYouJustPunchOutCthulhu the Hellbots]] are safe from getting replaced.
* BonusBoss: Both Saxton Hale and Unholy Bosses have a few of these running about. [[spoiler:Hale has Pissed Off Roll, [[OriginalCharacter Neo]][[AuthorAvatar DS]], Gamma's Feet, and [[Videogame/StreetFighter Gouki/Akuma]]. Unholy has bosses of this kind called "[[WebVideo/TheMisadventuresOfSkooks strongmen]]", which are Eyelento Major, Higlur, Zankokuna Hellbot, Final Faggasso, and Sampi.]][[note]][[spoiler:Their unlock conditions, in order, are to defeat a wave of Eyelentos in a rare special round (which comes without warning), defeat both Red Baron and Blue Jay at the same time (or have them both dead before the intermission screen appears; since V7, they have to be fighting each other in order for the unlocking of Higlur to work), defeat Hellbot before the timer ends, defeat 15 Faggassos, and have a survivor finish off a boss one-on-one ten times.]][[/note]] [[spoiler:The fan-made Unholy Rebellion expansion adds [[AuthorAvatar Lampi]]. [[note]][[spoiler:Have the moths win the lamp event five times.]][[/note]]
* BossGame: The Saxton Hale and Unholy Bosses mods are nothing but players gathering up to take down bigger, badder foes.
* BulletHell: The Gembanker in Unholy Bosses is an example of this. His main attack is [[GemstoneAssault firing gems]] that can [[RecursiveAmmo create other miniature gems that scatter everywhere]], which make them harder to dodge. His [[LimitBreak rage]] fires a black gem that can not only crash right through players, but can cause even more chaos by [[UpToEleven splitting into larger gems that split into even smaller gems]].
* CallBack: ''Justified Classes'' are full of this - '''big time'''. Every single character class featured in this mod tries its best to flawlessly replicate abilities that Robot Masters themselves use in the original Mega Man titles. [[spoiler:For example, Bass can not only use his rapid-fire Bass Buster, but he can also dash and perform double jumps - just like he does in ''VideoGame/MegaManAndBass''.]]
* DamageSpongeBoss[=/=]MarathonBoss: Because of its higher health levels and damage output (which are ten times greater than a typical mod, classes having 1,000 HP on average), certain bosses in Unholy Bosses can start with up to ''10,000+ HP'' if there's enough players. [[spoiler:Two of the BonusBoss[=es=] have starting HP of '''30,000'''.]]
* DeathFromAbove: Unholy Bosses has many examples of this.
** First, there's the meteor item, which, upon activation, spawns a large crosshair at the spot of it's activation, along with the voice line [[VideoGame/SonicAdventure "GET A LOAD OF THIS"]] and then a voice saying [[VideoGame/DonkeyKong64 "GET OUT"]] is heard, along with the meteor dropping down. When the meteor touches the ground, anyone within the blast radius is insta-killed, except those behind walls.
** The rage of both Astromancer Crasher and Astromancer Crusher has something similar, except without the voice lines, and a faster meteor drop.
** [[spoiler:Final Faggasso's rage, which drops a red and black meteor upon everyone, insta-killing them and causing a jumpscare for them.]]
* DifficultButAwesome:
** Class-based mods (especially ''Justified Classes'') tend to include at least a few playable classes that fall under this trope and may require a bit of skill to effectively use. Also, in boss mods like ''Unholy Bosses'', some bosses are this, like [[spoiler:Sampi]].
** In Unholy Rebellion, getting a kill with [[VideoGame/HenryStickminSeries Charles]]. You'd need to be in a crowd of players in order to have Charles collide with them for a lot of damage, or get the big guns to rip their health down. In both cases, players need low health.
* DiscOneNuke:
** Fake Man's Heat Man weapon, the Atomic Chain, in ''Mission Mode: Strength in Numbers'', with a good number of rounds and being able to kill most enemies in one hit and deals massive damage to mini bosses and [[BossInMookClothing Bosses in Mook Clothing]]. It making almost instant contact makes it more worthwhile, and the trail of fire it leaves behind will damage anything that runs into it.
** ''Aurora Cannon'' had a Charged Attack that unleashed a huge beam. And then, he learned to make a beam appear in a flash, from point A to B.
* DraggedOffToHell: In Unholy, an item called the Unholy Book can be used to suck in anyone within the radius and then kill them with a giant laser beam from the book. The kill message implies that this happened to the victim.
---> "(Player) told (victim) to go to Hell."
* DualBoss:
** Unholy had many bosses that were usually in groups until v7, where any boss could pair with another. Even then, having one of these groups appear in a round is still possible.
*** First, there's the Astromancers Crasher and Crusher. The two act identically, but the only real difference is their alt-attack: Crasher's is sending meteors down upon players, but Crusher's is sending them straight at players.
*** The Tankbois, which are Blue, Red, and Yellow. The Blue Tankboi mainly focuses on defense, and thus harder to kill, the Red Tankboi focuses on power, and thus hits hard, and the Yellow Tankboi focuses on speed, thus he moves quicker and fires faster.
*** In a similar vein to the Tankbois, there's the Anti-Unholy Elites. The red, blue, and yellow ones act similar to the above, but they have one more trick up their sleeve this time, with the addition of a purple Elite, which focuses on spread shots. Unlike the Tankbois, when the Elites get down to low health, they get a rune of each one's respective focus (Red gets strength rune, Blue gets resistance rune, Yellow gets rage rune, and Purple gets spread rune).
*** Skullman and Pharaohman, which are based on their VideoGame/Rockman4MinusInfinity boss fights.
*** The two Juggerbros: Gold and Silver. The gimmick with these bosses is one is stronger but slower (Gold), and the other is faster but weaker (Silver).
* EarlyBirdCameo:
** Quite an impressive case with the recent versions of ''Justified Classes'' mod. It features fully playable Stardroids and Sunstar from ''VideoGame/MegaManV''.
** ''Classes Based Modification'' would do this as well with the Robot Masters of ''10'' and ''V'', gradually rolling them out through updates.
%%* ExactlyWhatItSaysOnTheTin: ''Justified Classes'' mod lives up to its name very well.
* GangUpOnTheHuman: Played with in the third Wily Castle stage in the ''VideoGame/RockmanNoConstancy'' mini expansion's campaign; the match is played as Team Deathmatch rather than the free for all matches in all the other stages. The player is placed all alone on the blue team.
* HailfirePeaks: A plethora of custom user-made maps combine the stage environments of two or more Robot Masters into a single map.
* HeroShooter: Class mods turn the game into this, giving each individual character different weapons and abilities (some retaining the ability to collect weapons while many others are stuck with one loadout).
* JumpScare: Many bosses and items in Unholy Bosses can cause one.
** Hellbot can cause one to anyone who dies to him, with the face from [[FanFic/MARIObyMARIO MARIO]] and a loud scream.
** One of the True Buster Mistress's items is sending a hologram of herself straight forward, and if it runs into anyone, the victim gets the exact same jumpscare as Hellbot's.
** The Give Up Hope Unit (or GUHU) can be used to trigger the jumpscare and also jumpscare anyone within the blast radius.
*** The Super GUHU is a delayed version of the regular GUHU, with the user being surrounded by red skulls and the drowning music from ''VideoGame/SonicTheHedgehog1'' playing and muting the map music. After a while, it does cause a jumpscare, but while the scream is the same as the GUHU's, the face is replaced by the [[VideoGame/SonicTheHedgehogCD Fun is Infinite]] screen.
** Like the Hellbot, [[spoiler:[[BonusBoss Final Faggasso]]]] can cause jumpscares to anyone who dies to him.
** Both of [[spoiler:[[FinalBoss Sampi]]'s]] rages can cause jumpscares to unfortunate victims.
** The football item can jumpscare anyone who gets hit by it, but instead of a scream, the sound is from the original John Madden's Football, along with the jumpscare image being from the same game.
** Guts Buddy's item has him leap up in the air and cause a shockwave when he hits the ground, and anyone who dies to it gets a jumpscare screen of the infamous "Gutsman's Ass" in 8-bit, complete with the riff (in 8-bit, the same one from the Guts Dozer battle) as the jumpscare sound.
** In Rebellion, [[spoiler:Lampi]] can do this with his attacks.
* LethalJokeCharacter: The Generic Boss in Unholy. He's ExactlyWhatItSaysOnTheTin, being a boss that is, put simply, a standard Saxton Hale-style boss with only a simple punch, super jump, and rage. The punch kills in two hits for most classes (doing 500 overall) and has the benefit of ''canceling out a class's afterlife attack'' meaning that you cannot pray on a lucky hit from a dead survivor to severely weaken or defeat him and the only way to kill him is to use regular attacks and items.
** The Guts Buddy could also apply. Despite being a port of CBM's Gutsman class, his attacks are much faster and powerful and he also has a rage that has him throw an explosive rock that, while easily telegraphed due to its abysmally slow speed, can deal massive damage.
** The Fox Demoneyes. Even though they're Demoneyes in fox costumes, they can track players' locations through walls, and defeat them in one slap. It's the rarest Demoneye to morph into just for how it can easily turn the tides on itself.
* LethalJokeItem: A few in Unholy.
** The rubber band and the football. The rubber band is a small but fast and powerful projectile that one-shots if it connects. The football is slower, but killing someone with it also causes a jumpscare for them, which also prevents an afterlife attack.
** The Hacky Coffee causes a huge cluster of coffee-colored Ballade Crackers to spawn where it's placed, easily shredding the health bars of anyone that gets caught in the cluster.
** The "YOUDIE" item is another time-it-right item, but unlike the band and football, it's a hitscan projectile that explodes immediately on contact and similarly one-shots.
* LightningBruiser: Two bosses in Unholy are this: Dickster Dick and Prickster Prick. Both act the same somewhat, with their gimmick being that they're very fast and do contact damage to anyone they run into, but with the only change being their mainfires; Dickster's is becoming invincible and also [[TurnsRed turning red]], while Prickster's is a [[VideoGame/SonictheHedgehogCD super peel-out]], and Prickster lacks the spring that Dickster has for his alt-fire.
* LimitBreak: In both Saxton Hale and Unholy, most bosses have a rage that they can use after being hit many times. Most of these range from simple stat boosts to a powerful attack that does a lot of damage to survivors, usually having the power to instantly kill one or multiple targets.
* NumberOfTheBeast: In Unholy Bosses, Hellbot has 6,666 HP.
* OurZombiesAreDifferent:
** ''Roboenza Mode'' has the "infected", who can climb walls and automatically die after a certain amount of time. Then came a version (Roboenza Swarm) that worked similarly to the Infection (later Flood) gametype in the ''{{Videogame/Halo}}'' series.
** One effect in ''Chaos Generator Upgraded'' has more traditional zombies that quickly swarm the stage.
* PaletteSwap:
** The EX tier bosses in Unholy play similarly to their non-EX bosses but are much rarer and much harder to fight: [[spoiler:Jester Gelato, Prickster Prick, Incognito, WesternAnimation/ThomasTheTankEngine, Alpha EX, and Faggasso DX.]]
*** Though you might think [[spoiler:Thomas]] might not fit into the EX tier, he actually does, being an EX version of Meguh Mang.
** All three Hellbots. Whilst Shin Hellbot and Zankokuna Hellbot share most attacks, Hellbot has a somewhat unique moveset.
* PlatformHell: Lobster's Obstacle Course and its successor Ragestacle Course. Nearly every map has precession-jumping over very tiny, sometimes hair-thin platforms (on top of that, most jumps are only possible with strafe-jumping) and quite a few of them are MarathonLevel[=s=] with a plethora of OneHitKill traps, BottomlessPits everywhere, CheckpointStarvation, and sometimes making use of progression via utility weapons such as Thunder Claw, Mega Ball, Ice Wall, and Concrete Shot. Some of these weapons may be more finicky and hard to work with than others, and the maps expect you to come in with a full mastery of the weapons and their properties. The slippery physics of ''Doom''[='s=] walking and delay in-between jumps also contributes to the mod's difficulty.
* RedAndBlackAndEvilAllOver: Unholy Bosses' Hellbot, a Napalm Man colored crimson red and dark grey that darkens the entire map and comes with a fury of powerful attacks.
* RocketTagGameplay: In class mods that have weakness systems, there are indeed times where two players are weak to each other's weapons. (Such as Fire Man vs. Blizzard Man in CBM, or even [[HoistByHisOwnPetard Metal Man]] duels!)
* ScrewTheRulesIHaveMoney: Essentially the case with Unholy's Demoneyes. They can either attack players or the bosses, and the way to morph into them is to pick up a thrown money bag or be in the Money Bomb's blast radius.
** Subverted with Devileye's money bags, where if someone picks them up, they have to work with Devileye. Also the case with the Devileye Richman.
* SequentialBoss: Two bosses in Unholy Bosses have this trait; Cutty Cut and Toadman. With Cutty Cut, he starts out with a basic Rolling Cutter and has a melee attack with short range, and upon getting his health knocked to 0, he gets back up with an upgraded Rolling Cutter that can bounce of walls along with increased melee range, and upon the second time he gets knocked down, he comes back one more time with a Rolling Cutter that can stick to floors and walls, along with very high melee range. With Toadman, he uses a normal Rain Flush and leap attack, but upon getting his health to 0, he goes into a Rage Mode which replaces his Rain Flush with a more powerful one that also creates tornadoes, along with a leap that can make Flash Bombs fall to the ground. If Toadman does get hit enough times in this mode, he uses his DesperationAttack: Leaping all over the place, dropping Flash Bombs, causing tornadoes to appear, and utterly destroying anyone he leaps on.
* ShoutOut:
** From Classes Based Modification:
*** Needle Man is a direct clone of [[Videogame/TeamFortress2 the Heavy]].
*** If Toad Man charges up Rain Flush but releases the charge midway, he instead emits a croak taken from ''Videogame/BlasterMaster''. A similar occurrence can happen with Uranus, who shouts the cry of a [[Videogame/{{Pokemon}} Tauros]] accompanied with a "Moo!" speech bubble from the arcade game ''Karate Champ'' if he doesn't fully charge up his alt attack.
*** Wave Man's grappling hook on the HUD uses the sprite of a [[Videogame/TheLegendOfZelda Hookshot]].
*** Stone Man uses a few sounds from ''[[Videogame/SuperMarioBros1 Super Mario Bros.]]''
*** Prior to being retooled, Dark Man 3's weapon icons were silver and gold Rail Rings from ''Videogame/SonicRoboBlast2''.
*** If you kill the Evil Robot, you can pick up its parts, and you get a spreadrune if all are picked up. The parts are called parts of the "[[Franchise/YuGiOh Forbidden One]]".
*** Concrete Man uses a moveset and sound effects taken directly from ''Videogame/WarioLand'', including the Shoulder Bash and throwable blocks, charged up just like in ''Videogame/WarioLand3''.
*** Magma Man fights like a [[Videogame/{{Doom}} Mancubus]], shooting a two-spread Magma Bazooka angled depending on which key the player uses to fire.
*** Quint can dash, striking the same pose from the ''Mega Man'' fangame ''Quint's Revenge'' as he does so.
*** Ra Thor is chock-full of ''VideoGame/Sinistar'' references in his sound quips, even alluding to the "Initial Tests Indicate, All Systems Go" startup sequence when (re)spawning. When killed, he drops parts that resemble Sinistar.
*** Continuing with the ''Videogame/{{Doom}}'' references, Bad Box Art Mega Man plays exactly like a Doom marine, but with the hitscan effects of weapons removed and the weapons themselves nerfed in damage output to be more suitable in a [[PlayerVersusPlayer PvP]] environment (for example, the Super Shotgun is not likely to OneHitKill as it does in ''Doom'' multiplayer).
** [[BossGame Unholy Bosses]] does this a few times.
*** The most obvious one being the music for bosses being from other games (sometimes).
*** For classes, we have Zangief, who is based on the character of the same name from ''Franchise/StreetFighter''. The mod uses a very complex ACS to recreate Zangief's many different moves. The class itself was created for a class competition, and was then added to Unholy in Version 7 of the mod.
*** There's also the Red Warrior, Blue Valkyrie, Green Elf, and Yellow Wizard classes, all of which are a shout-outs to {{VideoGame/Gauntlet}}, right down to the taunts.
*** For bosses, we have the Faggassos, who are a reference to the Starmen from ''VideoGame/EarthBound'', even going as far as to incorporating a Ghost of Faggasso and Faggasso DX, along with having a BonusBoss, [[spoiler:Final Faggasso]].
*** Clownpiece from [[VideoGame/TouHou Touhou]] makes an appearance as a boss. In Rebellion, Hong Meiling, another character from the same franchise, is added.
*** "(Player) gave (victim) [[Manga/JoJosBizarreAdventure his quiet life]]."[[note]]If someone uses the [[BackFromTheDead Unholy Insurance]] item and loses all their health, an ambulance comes to revive the user, but if lucky, the ambulance can do damage to anyone that it runs into, and if someone dies to it, this message shows up.[[/note]]
*** The fan-made "Rebellion" patch has one in the form of another kill message, specifically with Storm Hayate's rage.
---> (Player) [[Literature/TheWizardOfOz wasn't in Kansas anymore]] thanks to Storm Hayate.
*** The Unholy Book has audio from the infamous Advertising/BigBillHells parody ad, mainly the "GO TO HELL!".
*** "[[WebVideo/TheMisadventuresOfSkooks Would you like to see the strongman?]]" is heard when encountering a BonusBoss.
*** As another shout-out to Skooks, using the malt shop item will trigger Fred's "Let's all meet back at the malt shop" line from Part 3.
*** Unholy Rebellion's Vampire Hunter class is a massive one to Franchise/{{Castlevania}}, having the Vampire Killer whip and many of the subweapons.
*** [[VideoGame/HenryStickminSeries Hey look, Charles is here!]] (only in Rebellion however)
* TakeThat:
** Plug Powerplant from the unofficial Unholy "Rebellion" patch is one to Classes Based Modification, created solely to make fun of the latter in general, but mainly the buffs and nerfs that come with each version of the mod.
---> '''UH OH! SOMEONE'S ABOUT TO GET NERFED!'''
** Cryptic, from the same mod, is one to the VideoGame/MegaManRockForce Classes mod, whose Crypt Man class was considered by many to be the worst one, and the class's code was so bad it couldn't be salvaged.
* TheMedic:
** In Mission Mode and Saxton Hale, Roll plays this role by shooting at targets with a special beam.
** In Unholy Bosses, Amber is capable of healing players by summoning health capsules in front of her. She was replaced by the Mad Maid (who acts similarly but has Roll's skin) in the unofficial "Rebellion" patch.
* TimeLimitBoss: In Unholy Bosses, matches are coded to end automatically after 10 minutes via killing every survivor on the map (via [[spoiler:Zankokuna Hellbot's rage]]) or [[WhyAmITicking forcing a Super GUHU]] onto everyone once those ten minutes pass. In the fan-made "Rebellion" patch, not only was it reduced to 6 minutes, but allowing the 6 minutes to pass can now cause the Wish Star's normal wish, which kills everyone instantly, and, sometimes, the rare [[spoiler:[[VideoGame/SonicExe Sonic.exe]]]] wish.
* TokenEvilTeammate: In the ''Strength in Numbers'' add-on for Mission mode, three of the added characters are villains that join the heroes on seemingly their own terms: Doc Robot, Dark Man, and Fake Man.
* TurnsRed:
** In ''Mission Mode'', the Robot Masters become this when half of their health is depleted. Toad Man floods his room with water, completely changing his attack strategy, while the other Robot Masters gain a DesperationAttack.
** In Saxton Hale, [[Videogame/PunchOut Super Macho Man]] and Gutsman G have desperation modes if they get up twice or wait out the timer respectively. As Gutsman G, this is particularly the only way he can win, as he's a GetBackHereBoss otherwise.
** A small pool of bosses in Unholy Bosses will enter a Desperation Mode once their health gets knocked down to a certain point, usually 1,500 health. For example, True Buster Expert gets a faster firerate and an increase in power (along with causing a BackgroundMusicOverride). Shin Negaman heals himself with Nega Skull Barrier (becoming invincible while healing up) and gains access to more powerful randomized attacks used via the item slot (including the all-powerful Nega Astro Crush), and Sinful Buster Expert acquires the Hellbot attack, his strongest attack that erupts explosive crackers everywhere.
* ZergRush: Demoneye parades in Unholy Bosses; One survivor (labeled as the "Faggot" pre-v7) is their class of choice while everyone else becomes a hoarde of Demoneyes on a quest to kill the survivor with ArmorPiercingSlap[=s=]. There are also variations of this event, including one where the survivor becomes a Demoneye in a [[Videogame/{{Pokemon}} Braixen]] costume (known as the "Furry Demoneye") that cannot attack, one where the Demoneyes are faced with a Fox Demoneye that can insta-kill and track the locations of the eyes behind walls, and one where the survivor is faced with dark clones of the Buster Mistress class (and all of the map is darkened). In the case of the Furry Demoneye and Fox Demoneye variations, there's a time limit for the survivor and Demoneyes respectively. If time runs out, either the survivor (in the Furry Demoneye variation) or the Demoneyes (in the Fox Demoneye variation) win.
** The unofficial Rebellion patch adds another variation. This time, the map is darkened, like the dark Buster Mistress event, but here, the mob is a swarm of moths (each player controlling a moth) without any attack, as they must find the lamp[[note]]an AuthorAvatar for community member Nosaj[[/note]] and swarm it (in reference to the Moth Lamp meme). If close, the moths gain health if the lamp's light is on, but if its off, they lose health. The lamp must try and use the light to see through the darkness, but at the risk of the moths swarming it.

*** If Toad Man charges up Rain Flush but releases the charge midway, he instead emits a croak taken from ''Videogame/BlasterMaster''. A similar occurrence can happen with Uranus, who shouts the cry of a [[Videogame/{{Pokemon}} Tauros]] accompanied with a "Moo!" speech bubble from the arcade game ''Karate Champ'' if he doesn't fully charge up his Alt attack.

*** If you kill the Evil Robot, you can pick up it's parts, and you get a spreadrune if all are picked up. The parts are called parts of the "[[Franchise/YuGiOh Forbidden One]]".

*** Continuing with the ''Videogame/{{Doom}}'' references, Bad Box Art Mega Man plays exactly like a Doom marine, but with the hitscan effects of weapons removed and the weapons themselves nerfed in damage output to be more suitable in a [[PlayerVersusPlayer PvP]] environment.

* JumpScare:
** Wily delivers one to [[spoiler:Mr. X at the end of Chapter 6 (Version [=5B=]). He shouts "FOOLS!" and quickly close-ups his face to the monitor, causing Mr. X to run screaming in horror.]]
** Done by [[spoiler:the Evil Robot right before his saps the power of the [=MM8=] Robot Masters and flees into outer space]].
** Chapter 13 provides another one. [[spoiler:As Cossack talks to Maestro after half of the Stardroid arenas are completed, Toad Man gets scared by the sight of what remains to be Evil Robot's head still hovering in space.]]
** In the same chapter, after completing all of the Stardroid stages, [[spoiler: something impacts with the back of the Cossack Cruiser. When the player goes to check it out, the airlock explodes and the player is face-to-face with Terra, who then [[ThrownOutTheAirlock tosses them into space to fight them]].]]
--->[[spoiler:'''Terra''']]: Hello, Maestro...

* AdaptationalVillainy: Downplayed. The Stardroids were always a villainous group of robots reprogrammed by Dr. Wily in Megaman V to take over the world, but in here he has had no hand in their programming; here they become an OmnicidalManiac cult hell bent on awakening Sunstar and infusing him with the power of The Evil robot to ''destroy'' the world, essentially making them more like their versions from the Archie Comics and Gigamix. Out of all of them, Terra is the most psychotic.

* BilingualBonus: In Chapter 13, [[spoiler:the 8 artifacts you give to Pharaoh Man will spell out "lanfront" in Japanese once fully arranged. Fitting, since they hint you towards Lanfront Ruins]].

* BoringButPractical: The Needle Cannon, and possibly Yamato Spear and Quick Boomerang qualifies as this. Their function is very simple when compared on most other weapons; Has better damage and better rate of fire than the default weapon. The Yamato Spear can penetrate through enemies and Quick Boomerang has a faster rate of fire, but has a low range.

* BossOnlyLevel: The map titled in-game as ''Unknown'' is a specially designed map where all the single player bosses are fought in "separate" areas. In fact, attempting to play a normal multiplayer game on it will automatically redirect all players to Cut Man's map. Two more ''Unknown'' maps were added in Version 5 to house its new bosses.
