* [[AwesomeBosses/VideoGames Best Boss Ever]]: Vulturon, who fights with ThePowerOfRock.
* CargoShip[=/=]TrademarkFavoriteFood: [[http://karinexe.deviantart.com/art/Random-Stupid-Comic-4-38021627 Judging]] [[http://rockmiyabi.deviantart.com/art/Love-Your-Coffee-More-Than-Me-114047553 from]] [[http://snakequeen.deviantart.com/art/Do-you-want-some-coffee-72634589 some]] [[http://starwolftsuname.deviantart.com/art/Girouette-speaks-56139924 fanarts]] ([[http://gmlink.deviantart.com/art/Happy-Lil-Girouette-49572874 compiled]] [[http://samusmmx.deviantart.com/art/For-KarinEXE-Giroette-gift-41921854 for]] [[http://hikaruthered.deviantart.com/art/Good-to-the-last-drop-43050503 your]] [[http://bright-as-a-button.deviantart.com/art/I-Need-More-Coffee-85880477 convenience]]), some fans like the "Giro X Coffee" pairing. (Mostly stemmed from [[http://crystalclear4everl.deviantart.com/art/giro-from-megaman-zx-158163052 this image.]])
** And have some sweet [[http://www.youtube.com/watch?v=rFaYmdTGLAc Coffeedansen.]]
* CrazyAwesome: Prometheus.
** Fans also see Vulturon as this. A headbanging [[NinjaPirateZombieRobot robotic vulture skeleton]] who uses a guitar for a weapon. Not crazy enough? He can use said guitar to ''reanimated discarded metal, thereby creating zombie robots.'' And he does use that guitar for performances... usually to aforementioned zombie robots. His quirky rocker personality helps a lot.
* EnsembleDarkhorse:
** Much like [[VideoGame/StreetFighterAlpha Charlie]], Giro has amassed a sizable fanbase despite being dead.
** The {{fandom}} has gradually taken quite the liking to Prometheus and Pandora. And if anything, when they were discovered to be [[spoiler:[[WoobieDestroyerOfWorlds Woobies, Destroyers of Worlds]] and then subsequently ''owned'' by Albert (in the span of five minutes or so, no less),]] their popularity among the fandom hit critical mass. [[spoiler:For some, ''that'' was Albert's MoralEventHorizon.]]
** Of the ''ZXA'' cast, Vulturon, for reasons explained above.
* FauxSymbolism:
** This seems to be what happened with the names of all the Biometal Users in ''ZXA''. While Atlas, Helios/Aeolus, Siarnaq, Tethys/Thetis, Prometheus and Pandora were all supposed to be Saturnian moons, when you look at them in the context of Greek Mythology, they appear to be a random collection of Titans and other mythological figures with no other real meanings behind their names.
** Also, the Sage Trinity has nothing to do with a Trinity, God, or Christianity. Apparently, they are named that just because there is three of them and it's just a translation choice anyway (their Japanese name translates to the connotation-free "Three Sages").
** Siarnaq is actually the name of a giant from Inuit mythology.
** Also noteworthy is the fact Homer often referred to Helios as Titan or Hyperion -- both moons of Saturn.
** Prometheus was the Titan who stole the secret of fire from the gods. The character in question here is self-explanatory in that regard.
** Pandora's Box was a legendary artefact that reputedly brought mass ruin upon the land in which it was opened. Pandora here turns out to be suppressing her true persona and agenda. She is outwardly calm and emotionless, but reveals herself to have an insane, vengeful side when the player gives her that extra push.
* FridgeBrilliance: Why do the Pseudoroids have extra eyes? [[spoiler:It's likely a property of [[ArtifactOfDoom Model W]], and considering it is very much a EldritchAbomination thematically, and that Humans and Reploids are and consider each other the same now the logical conclusion on exactly [[BodyHorror how this would be seen as by the people inside the setting.]] Add in the dialogue the Pseudoroids have and you realize that at least some of them (like Purprill) were around at least in some form before gaining the power of whatever Model they were infused with; with their absolute devotion and belief to Model W you realize that they are mutilated cultists.]]
** The tagline from this [[http://www.youtube.com/watch?v=6_6QGlvHNP8 Japanese promotional trailer]] ("When fate must be stood up to... people shall Rock On") really explains the ScrewDestiny theme of the series, and the Biometal's power to shape the Biomatch's destiny, as elaborated by Ciel.
** The Enemy Mega Men and Albert's CoDragons' names are taken from the moons of Saturn. Saturn is known for its giant ring. Guess what shape Albert's collective Model W ({{Ouroboros}}) is?
* GameBreaker: Model ZX's rolling slash, which can bypass MercyInvincibility and deal continuous damage as Vent/Aile's still spinning. And after that, you can still follow up with your standard triple slash.
** Model P's kunai spam is murder against enemies without MercyInvincibility. Wipes out everything in seconds.
** Model HX's tornado attack, which can hit multiple times and also can pass through MercyInvincibility if the tornado hits the weak point. Try to do it with a fire boss: [[ElementalRockPaperScissors Superior element]] + [[DeathOfAThousandCuts multi-hitting]] + [[AttackItsWeakPoint attacking the weak point]] = [[NoKillLikeOverkill Overkill.]]
*** The downside, though, is that you'll get Lv 1 Victory, so you'd better do that in the boss rush. Unfortunately, it was later {{nerf}}ed in ''ZXA'', the attack instead generating two tornadoes that fly forward and only hit once.
** Chronoforce's [[BulletTime Time Bomb.]] Its only downside is that it uses a lot of weapon energy. It also loses all functionality in the final battle with Master Albert, who specifically whips out his ''own'' Time Bomb just to counter yours.
* GoddamnedBoss: Thetis makes sure to fight you underwater where he has such an edge [[TheComputerIsACheatingBastard it's almost unnatural]], and he employs constant hit-and-run tactics while you're trying to keep your footing (on the three tiny ledges they give you) above a BottomlessPit. [[VideoGame/MegaManX Gate]] tried similar cheap tactics in ''X6'', but Thetis perfects it. Have fun with all this on Hard Node and [[BossRush Boss Survival]], by the way!
* HilariousInHindsight:
** Master Albert's goal: [[TheSocialDarwinist exterminating the whole population, leaving the "worthy" ones alive to prosper,]] using a superweapon called {{Ouroboros}}. He's seen to be a highly-capable MagnificentBastard who has a strong [[AGodAmI god complex]], to boot. Now try to compare that to another [[VideoGame/ResidentEvil5 Albert]]. [[note]] ''ZXA'' precedes ''[=RE5=]'' by a margin of about 2 years. [[/note]]
*** It doesn't stop there. Both games feature two [[TheGunslinger gun-slinging]] protagonists -- one male and one female, and at one point in the game, they have to fight the protagonist from a previous game.
** Might be intentional on the creators' part: ''Advent'' featured an unlockable mini-game, ''Mega Man a'', all in 8-bit, styled after the original series of games. A few months later, ''VideoGame/MegaMan 9'' was released, in all its {{retraux}} glory.
* JerkassWoobie: Prometheus and Pandora. [[DarkAndTroubledPast Their childhood was, to say the least, horrible]] [[note]] They had to suffer through centuries of anguish from Master Albert, including being forcibly and permanently Megamerged with Model W, and are also strongly implied to have had other Mega Men participate in the Game of Destiny (thus causing casualties assumed to be in the hundreds of thousands range) only because Albert forced them to due to their intentionally short lifespans, which could only be marginally extended by coming back to Albert for maintenance checks [[/note]] and they want revenge for their suffering. They don't quite succeed (with Albert being a MagnificentBastard and all), and end up as Albert's {{Unwitting Pawn}}s. [[AlasPoorVillain Even Grey and Ashe feel pity for them]], [[SaveTheVillain and would have tried to save them if they had the chance.]] Even so, they held nothing but contempt for the rest of the world, and while their actions ''do'' [[StealthMentor guide the heroes toward defeating Serpent and Albert]], there was no kindness in their cruel actions. [[ItsAllAboutMe Their only concern was themselves and each other]]; everything else was just a liability in their eyes. This includes [[spoiler:their younger brother Grey, who spends ''ZXA'' as an amnesiac kid swept up in events he wants ''no'' part in.]]
* JustHereForGodzilla: Arguably, but a good portion of ''ZX'' fans are Just Here for [[TransformationTrinket Biometals]]. More specifically, "Just Here for Playing as the Favorite Characters Who Come Back as Pieces of Metal that You Can Use to Change into Said Favorite Characters." [[note]]It makes sense, actually, especially for [[InfinityPlusOneSword Model OX]], which is based on [[EvilIsCool Omega]] from ''[[VideoGame/MegaManZero Zero]]'' series. [[/note]] As a result, many fan arts for this series are about "Hey look! This is Model (insert your favorite character here)!" And the favorite character in question could be any character from the series (be it a major character or just a random boss) [[note]][[http://shadypenpen.deviantart.com/art/RM-ZX-Forte-Concept-Lineart-27716953tThese]] [[http://kyujix.deviantart.com/art/Elecman-EXE-ZX-Style-178524981 are]] just a few examples[[/note]], a character outside the series [[note]][[http://arbucias93.deviantart.com/art/Batman-ZX-Style-97465819 these]] [[http://omegaslaserdude-exe.deviantart.com/art/Kh2-Sora-and-Roxas-MMZ-style-137173426 are]] just a few examples[[/note]], or even an original character.[[note]][[http://randypandy.deviantart.com/art/Biometal-Model-R-ZX-Style-127854868 these]] [[http://sinkato.deviantart.com/art/Megaman-ZX-ELG-Pseudoarmor-49683562 are]] [[RuleOfThree just a few examples]][[/note]].
** The [[FusionDance Double Megamerge]] system, which lets you transform with two Biometals. As a result, many fans used it to mix their 2 favorite models into one character. [[note]][[http://shadowfox777.deviantart.com/art/Double-Megamerge-AX-Vent-167780913 These]] [[http://shanna-the-hedgehog.deviantart.com/art/WHYWHYWHYWHYWHYWHYWHYWHYWHYWHY-108347483 are]] [[OverlyLongGag just a few examples.]][[/note]]
* LoveToHate: Prometheus and Pandora.
* MagnificentBastard: Master Albert, all the way. [[spoiler:As well as Master Thomas, it seems.]]
** [[spoiler:The latter set up a GambitRoulette of ''his own'' to combat Albert and killed off his former ally by making it into a mission for the heroes. As much magnificence as Albert whipped out, Thomas may have actually outdone him.]]
* {{Moe}}: How a good portion of the fanbase sees Pandora [[spoiler:especially when she and Prometheus are revealed as [[TheWoobie characters who need a really, really big hug.]]]]
* MoralEventHorizon: Many fans hate Serpent because he killed [[EnsembleDarkhorse Giro.]]
** What the player finds out during endgame is ''even worse''. [[spoiler:People are kidnapped by Slither Inc. during the uprisings and held captive. Serpent then preys on their fears to involuntarily transform them into Cyber Elves, which are then absorbed by Model W as sustenance.]]
* NarmCharm: Activating a Biometal in the Japanese version prompts a cry from "R.O.C.K. On!" from your character. Woolsey'd to "Megamerge" in English.
* PlayerPunch:
** Not only does Albert [[spoiler:kill off the then-[[TheWoobie Woobie]]fied Prometheus and Pandora]], but he [[spoiler:steals their DNA with his A-Trans, meaning you can't mimic their forms.]] The bastard!
** Long before that, Giro is established as a nice, protective guy, before Serpent killed him off.
* ThatOneAttack: Some of the bosses have this. One example is Prometheus's skull flame attack where he summons skulls at the corners of the screen that fire at you simultaneously, requiring tricky maneuvering to avoid. Mitigated a bit by the fact that the skulls can be destroyed.
** Serpent's (2nd form) flame attack can also be pretty rough. With him firing off four flaming rocks that stay on the ground while slow falling flames fill the entire screen and home in on you.
* ThatOneBoss: Flammole if you're going for a Level 4 victory. Why? His weakpoints are his arms. His arms make up the majority of his sprite. We're talking like 75% of it. In addition, the only time his arms aren't vulnerable is when he's stationary (from the front). The problem? He's only stationary for a brief moment in between his attacks, meaning hitting him without damaging his arms requires quick action and ''very'' precise timing.
** Fistleo if you want a Level 4 victory. His weak point is his freaking ''head''. A majority of your attacks will hit his head and he has some hard-to-dodge attacks. On top of that: the bastard can ''heal'', and he does it frequently. So you have to constantly be on the attack to keep his health down. If you're going for a Level 4 victory, this means you have little time to make sure his weak point is out of your attack range before striking. Bonus pain if you're playing on Hard.
** Fistleo is pathetically easy compared to Flammole because, amusingly enough, Model HX's triple combo doesn't hit his head if you use it with your back facing him, and in Overdrive the triple combo hits ForMassiveDamage.
*** See [[http://www.youtube.com/watch?v=xHZdtDAszmo here.]] You may want to have clean pants standing by.
** Strangely, it seems both fire-themed bosses from the first game ended up as ThatOneBoss solely for Level 4 victory attempts.
* ThatOneLevel: Area K. Oh god, the lava... And see ThatOneSidequest below.
** The Ouroboros stage. There are blocks that can be destroyed and then regenerating. If you're standing on the block's space when it fully regenerates, you die. There's also [[SpikesOfDoom spiked]] regenerating blocks and BottomlessPits right under them. Oh, and this part (Ouroboros-3) is right after the BossRush and right before the FinalBoss room. Have fun.
* ThatOneSidequest: The Area K subtank. The fact that you can't get it on Hard Mode counts as ''mercy.''
** The Area X Sub Tank as well. It's much easier than Area K's, but it involves nearly '''40 minutes''' of running back and forth to Area L, going through (at least part of) the stage ''12 freaking times'', to pick up items for [=NPCs=]. There is even a bit of GuideDangIt to boot, since you are not told just where these items are or that your reward will change if you keep doing it enough times.
* TierInducedScrappy: ''ZXA''[='s=] Rospark form, of the low tier variety, since it moves very, very slow and its only useful gimmick is climbing ropes.
* TooCoolToLive: ''Another'' point for Giro on the list of Zero {{Expy}}ness. Unlike Zero, however, he ''doesn't'' get better (although he ''does'' [[AscendToAHigherPlaneOfExistence become a Cyber Elf]]).
* UnfortunateImplications:
** Deerburn was changed to Buckfire in the American release of ''Advent'', complete with stereotypical "red man" voice.
** [[AllThereInTheManual According to the manual]], [[CampGay Rospark]] is gay due to faulty circuitry. Not too long ago, homosexuality was academically considered a mental illness.
* ViewerGenderConfusion: Struck everyone who was paying attention to ''Advent'' previews with respect to Atlas and Tethys (see TomboyishName for one of the reasons). The first images of the enemy Mega Men showed them in armored form, so fans had no clue that Atlas was a "she" and Thetis was a "he." It did not help that their Japanese names (Atlas remained unchanged, while Thetis was Tethys) were that of a Titan and Titaness, respectively. Likewise, their Biometals were a man and a woman. Thankfully, this was rectified by gameplay videos and subsequent artwork, but the {{Fan Nickname}}s of "Reverse Trap" and "Trap" would stick.
* WhatAnIdiot: The respective protagonist calls the Enemy Mega Men out for [[IdiotBall their simple-minded persistence in continuing the Game of Destiny]], even with Master Albert's defeat looming over the horizon.
* {{Woolseyism}}: "Live Metal" to "Biometal"; "Falseroid" to "Pseudoroid"; the aforementioned [[FunWithAcronyms Fun Acronyms]] and [[NarmCharm Charming Narm]]; "Girouette" gains the nickname "Giro"; "Helios" to the much-more-sensible-for-an-air-elemental "Aeolus"; "Serpent Company" to "Slither Inc."; a few boss names as well (although one simply goes from "Condorrock the Vulturoid" to "Vulturon the Condoroid"...).
