Mega Man ZX is another entry in Capcom's flagship series, set about two centuries after the events of Mega Man Zero. The wars between Human and Reploid have finally been ended through the process of modifying both races until they're completely indistinguishable from one another. Even so, the threat of Maverick attacks still remains, although the cause of these outbreaks are entirely different.It currently consists of two games:
Mega Man ZX, starring Vent and Aile, a pair of orphaned Humans who are taken in by a courier service named "Giro Express" after its owner, the reploid Giro. And are tasked with recovering a quartet of Biometals by a peacekeeping force known as Guardian, before they fall into the hands of Serpent, a popular (but evil) CEO looking to find the Biometals to further his own divine evolution.
Mega Man ZX Advent, which takes place four years after ZX and stars Grey and Ashe (the former's a Reploid, the latter's an augmented human like Vent and Aile), who team up with the Biometal Model A to uncover their mysterious pasts and stop Master Albert, a rogue member of the world's ruling triumvirate out to pull what Serpent tried in the last game, only a thousand times over.
Currently has a small growing character sheet. Please feel free to contribute.Has no relation with BIOMETAL, a completely different game.
The Mega Man ZX games employ the following tropes:
In the first game, when you talk to the civilians when you're Megamerged, they'll flip out, as you'll be mistaken as a Maverick. You have to transform back into your human form first.
Played differently in the sequel where you can talk to the civilians in Model A form, and if you are using another form when you're going to talk to them (or when you're entering cutscenes), you'll automatically transform intothe Model A form.justified in that said civilians are all Hunters and fully aware of Biometal, Pseudoroids and Mega Men, where as the civilians in ZX are just your average townsfolk.
ZX's final battle theme is titled "Pallida Mors" (pale death).
The Biometals' passwords in the first game are split between this and Canis Latinicus.
Alluring Anglerfish: Lurerre from ZX is mostly shown as a robotic mermaid, but the "mermaid body" is actually her lure - her big, ugly body is offscreen most of the time, and sometimes appearing to launch a strong attack.
Ambiguously Gay: Rospark may be a robot, but he sure acts the part. A rose-based Pseudoroid with a clownish voice who enjoys fighting Grey while acting like Ashe is full of cooties, has a large, pink very phallic rod at his groin area (but also another one on his head), and is a rose... Is there any other way to take that?
Artifact of Doom: The original Biometal, Model V/W, fits this like a glove. Granted, it holds the essence of the Complete Monster of the previous series...
The Corruption: Specifically, it corrupts people who tries to use its great power.
Attackable Pickup: Any large powerup can be carved into several smaller powerups of different types using a bladed weapon. So if you didn't need all that health or weapon energy, or you just don't care about 64 more E-Crystals at the moment, or you desperately needed a certain powerup but you couldn't get any, get out a saber.
Attack Its Weak Point: Partially subverted. The idea in ZX is to avoid hitting the enemy's weak point, because doing so makes it cost more to repair the enemy's Biometals (not that it costs very much in the first placenote unless you're playing Hard Mode, in which case even the cheapest repair phase is ludicrously pricey) once they're salvaged (and you don't get the boss plushie for the mobile in Prairie's room). Several medals in ZXA require that either you don't hit them or you hit only them.
Audio Adaptation: ZX Gigamix, a CD which contains the remixes of the themes in the games, as well as drama tracks, which serves as manuals.
Ax-Crazy: Prometheus is a straight forward example, while Siarnaq appears to also be this despite coming off as emotionless.
Bad Export for You: The European release of Advent removes the english voice acting almost entirely.
Bag of Spilling: Despite the fact that you're not playing as the previous Hero/Heroine in Advent, the whole plot is the fact that the Big Bad (through Prometheus and Pandora) has stolen Vent/Aile's other Biometals and is putting them to use. He/she shows up looking for them later.
Chekhov's Skill: Model A's homing shot in Advent. While it is useful in the normal stages beforehand, the final boss fight is one time when the homing shot is essential.
Chest Monster: Some life-up power ups are actually Mechaniloids in disguise. They glow purple while genuine life-ups glow orange.
The Chosen One: In a slightly different sense - here, being "the Chosen One of Model (insert letter here)" just means that you can access the Biometal's power; but since it's implied that Master Albert did the choosing, with his special blood donation, which means that the Mega Men are "destined" to be so, this trope is still played straight.
The final level of Advent, Ouroboros, has a striking resemblance to Ragnarok from Zero 4. This is because Ouroboros was made from hundreds of Model W, which were spawned from Ragnarok. Also, Model Z disappears inside, much like how Zero "disappears" in the destruction of Ragnarok.
Two of the cars from Mega Man Battle and Chase appear, and the E-Tank makes a triumphant return.
The Guardian Base is powered by the Ciel System.
The first part of the Arctic Ice Floe area in Advent has a background similar to the background of the first part of the X1 Intro stage.
One of the missions you undertake at the Floating Ruins in ZX Advent have you searching the ruins for outdated artifacts; these include the L Tank from 4, the ever-recurring Energy Balancer, the Yashichi recovery item from the original and Mega Man 8 (called "Pinwheel" in-game), and the Lightbulb which served as life energy back in the original Mega Man. All four of these items are given explainations for their antiquity by the time of ZX (i.e. the L Tank was never mass-produced, etc.).
The entire Sage Trinity is named after the main scientists of the original series: Master Thomas = Dr. Light, Master Albert = Dr. Wily, and Master Mikhail = Dr. Cossack.
Some levels in the first game have the remains of bosses from the Zero series lying in the background. You can notice this early on, during the first boss fight.
Courier: The Giro Express transporters are essentially this.
Crutch Character/Disc One Nuke: Model X, to an extent. What makes him useful is that his double buster can be used in quick succession For Massive Damage. He's still good after you finally get him back. Too bad you can't use him on the final boss. He's an immense help on the penultimate boss, and you probably want Model H on the last boss anyway.
Serpent in the first game has an ability to summon thunder strikes that could instantly take down the target, but he only does that in the cutscene of his first appearance. Probably justified with the fact that he was outdoor when he did that; he later appears in a cave and then in the Slither Inc. HQ.
Prometheus' signature wave attack ranges from just does heavy damage to anything it hit (Grey/Ashe in the cutscene on the first train level) to outright One-Hit Kill (Albert's decoy body in the cutscene on the Underwater Volcano level). Of course, it won't result in that in his boss fight.
Pandora is able to create Beehive Barriers, but she never do that in the boss fight.
Aeolus in the second game can float indefinitely in cutscenes, but when you (as the copied form of Model A) try to do that, you'll fall down slowly. Though this one's justified; see Redemption Demotion below.
Cyborg/Transhuman: All of the humans in the ZX world; there's even a law for giving humans cybernetic implants, as said by Thomas.
Disadvantageous Disintegration: A milder variant in the first game: While you can still get the Biometals after beating the 8 bosses, the more you hit their weak points, the more damaged the Biometal gets, and thus the less energy they will be able to store.
Doomsday Device: Albert's Ouroboros qualifies, as it's the instrument he used to "reset" the world. The theme song which is played in the instrument (yes, said instrument is also a stage) is even called Doomsday Device.
Chronoforce looking to "take my time manhandling you" during the Boss Rush rematch.
Just about everything Queenbee says could be subjected to this.
Dropped A Bridge On Them: Being popular characters from the Zero series, the 4 Guardians were included as biometals in this series. However, you have to be dead before you can be a biometal, so the Guardians were abruptly declared to have died at the end of Zero 3. Apparently by standing too close to Omega when he blew up.
Spidrill from the Tower of Verdure is potentially the second boss you fight. It does a lot of damage, has hard-to-dodge attacks, and you can die instantly from spikes. And you have little health at this point. To make matters worse, it's only a mini-boss.
The intro level in the second game also qualifies; unlike the first game which gives you Model X from the start, here you're forced to play with your base form wielding a standard peashooter.
Emotion Eater: Model W feeds on negative emotions (anger, sadness, fear, etc) to grow and be activated. This is probably because Model W is the essence of Complete Monster Dr. Weil, whose sole enjoyment in life was causing people to suffer. This is also justified on a deeper level; if you read the sourcebooks and extrapolate a little, it's implied that Dr. Weil's insanity was shaped partially by hisownfear of Mavericks. Serpent powers up Model W by feeding it what is explicitly stated to be the souls of people who died while in the grip of fear!
Serpent: Model W, it's time! The despair and fear of this country are yours!
Aeolus, Atlas, Siarnaq, and Thetis for Harpuia, Fefnir, Phantom, and Leviathan are the most obvious ones.
The title character him/herself. Mega Man ZX is the Expy of Zero, gameplay-wise at least.
Girouette is one, to Zero himself. Both being Big Brother Mentors to the heroes, having blonde hair and red color schemes, and apparently sacrificing himself to save the heroes. Not to mention being the Biomatch for Model Z.
The similarity of two of the four "enemy Mega Men" with their original counterpart is scary. Aeolus and Siarnaq both carry some of Harpuia and Phantom's admirable traits, except probably for honor.
Like it or not, Model A and the Mega Man that results in the transformation, is still an expy of The Scrappy of the X series.
Grey and Ashe themselves can be considered split-expies of Axl. Ashe has Axl's cheerfulness, cockiness and recklessness, while Grey is an amnesiac boy who wants to know about his origins, much like Axl.
Prairie may as well be an expy of Ciel herself. Then there's also the fact that she is hinted at having romantic feelings for Giro.
The Sage Trinity are named after characters from previous Mega Man series (Albert Wily, Thomas Light, Mikhail Cossack). Played straight with Albert, who proves to be evil and treacherous like his namesake, but subverted by Thomas, who turned out to be a not-so-benevolent figure in ZXA's secret ending.
Pandora (more prevelant in civilian form) given similar hair color, hair length, hair style (barring the front) preference for white and blue (hue is different), and the fact that their nasty pasts drive them to madness may be a subtle one to Shion Sonozaki.
Vulturon: Zombielike? Check. Uses a guitar? Check. Has a crazy rocker personality? Check. He must've been taking some notes from Lord Raptor.
Extra Eyes Sensors/Eye Sensors Do Not Belong There: Many of the Pseudoroids and Serpent's One-Winged Angel Form have extra sets of eyes somewhere on their bodies, Some are rather hard to notice like Vulturon'snote Look at his official artwork and think how he would look without his head. and some are rather obvious like Lurerre's, the mechanical nature of them means that it is more cool then creepy though...
Fanservice: Okay... so, in a non-sexual way, most of this game is fanservice. However, the Double Megamerge for Aile sure does take its time letting the armor on her legs activate, especially when Vent's just click into place.
Advent includes a minigame based on the NES Mega Man games. And then Mega Man 9 came out, done by the same developer, Inticreates.
There's also more foreshadowing on the Game of Destiny (which is then fully revealed in the second game) in the first game.
And in the second game, there's many Cryptic Conversations that involves, in Grey's words, "the 'HIM, HE and HIS' guy". He's then revealed to be Albert.
Fun with Acronyms: M.E.G.A. (Meta-Encapsulated Granule Awareness)/R.O.C.K. (Rebirth Of Crystallized Knowledge).
Fusion Dance: Biometals X and Z (not the actual Mega Men) that form the title character.
The Biometals act as a Power Booster for humans and Reploids, turning them into "Mega Men" and granting them armored forms and abilities.
Gambit Pileup: ZX Advent is a veritable Gambit Casino, due to the number of villainous factions and the fact that none of them particularly like each other. Specifically, the enemy Mega Men are trying to accumulate Model Ws (as per Master Albert's Game of Destiny) in order to become incredibly powerful. Albert is just using them, however, to feed the Model Ws so that they'll become the Ouroboros. The Mega Men know this, and are planning to backstab Albert, then fight amongst each other until only one remains to inherit Model W. Then there's Prometheus and Pandora, creations of Albert who in the previous game claimed to be the voices of Model W (after pretending to work for that game's Big Bad), but are now inclined to destroy everything that Albert made, including Model W. After the game is beaten on Hard mode, it turns out Master Thomas actually wants to reset the world as well, but in a different manner than Albert, hence why he wanted the latter killed. As for Model W, it stands to gain from any of these things happening, and is probably manipulating the entire cast, given its origin as explained in the first ZX game.You got all that?
In the first game, your fight with the Pseudoroids is measured in Level 1-4; Level 4 means that the weak point didn't get hit, and Level 1 means that the weak point was hit a lot. The higher your success level, the longer the Overdrive Gauge the Biometal you acquired has (although if you get a Level 3 or lower, you can either repair the Biometals with a price, or doing a rematch with the same Pseudoroid later).
In the second game, you'll got bronze, silver or gold medal if you follow the Self-Imposed Challenge on the specific Pseudoroids. Collecting all 24 of them will grant you the "Model a" (note the lowercase).
Game Within a Game: There's an arcade in the first game where Vent/Aile (or, indirectly, you) can play some minigames.
Good Colors, Evil Colors: Isn't it interesting that all the protagonists in both games have green eyes, and all the non-pseudoroid antagonists (including Master Thomas) ALL have red eyes? Giro has blue eyes, too, though that's kinda irrelevant.
Goomba Stomp: Bifrost's form can be used to crush enemies when you fall on them. Justified, he's frickin huge.
Guide Dang It: The missions in each game require you to travel to the location where the mission takes place, unlike other Mega Man games where you're just teleported there. Unfortunately, you don't get good hints as to where these places are, making it very easy to get lost in the Metroidvania world.
Grey: Who's this!? He's different from the other Mavericks... Buckfire: Me not Maverick! Me Pseudoroid. Me Buckfire! You get away from Prometheus and Pandora, but not from I! Buckfire obey rule! Buckfire will pummel you into ground!
I Am the Trope: When the 6 Biometals in ZX gives out their passwords to unlock the door leading to Model W, we got this:
Model H: I am the wind that blows through the sky, Ventus Airus. Model L: I am the water that flows across the land, Glacius Passio. Model F: I am the fire that brings heat to all life, Flamma Wies. Model P: I am the shadow that never leaves the side of justice, Umbra Profess. Model X: I am the light that illuminates all possibilities, Lumine Infinitus... Model Z: I am the courage that fights for beliefs, Fortitude Creed...
I Am Who?: The protagonists said this word-for-word in the games. The ones who play the trope the straightest is Grey and Ashe, as they don't know who they really are.
Model L enables you to control ice. In the second game, Thetis is its Biomatch.
Pandora, though she uses Model W instead.
I'm Having Soul Pains: In Advent, acquiring a Biometal's data causes Model A to unlock Exposition, causing Grey/Ashe intense pain. Acquiring Model Z and Model X's data also causes Aile/Vent to suffer backlash for some reason.
Infinity+1 Sword: The aforementioned Model OX. Arguably Model X as well, because of the methods of unlocking it.
Interface Screw: Those annoying satellite dishes in Area L. Blue soundwaves will reverse your controls, while red ones will prevent you from attacking. Thankfully, the effect wears off, but it's enough for many players to consider Area L That One Level.
Serpent says that the blood of the Model W's creator runs in Aile's veins. ZXA reveals that he was referring to Master Albert, who donated his blood to certain survivors of Maverick Raids, thus giving them the key for Megamerging. Those "Chosen Ones" (as seen in Aeolus' cipher) later become the Mega Men.
Played straighter with Ashe, as she is an actual descendent of Albert himself.
Invisible Monsters: Advent has these kind of robo-mooks; Model P's radar is useful on locating their position.
Ironic Episode Title: Advent (means "the second coming") is a second game of the series, yes, but the titular Mega Man ZX is not the hero of this game - They're replaced with Grey/Ashe and Model A.
Then again it could also refer to the second coming of Model W.
I Wish It Were Real: This series are about kids who get the ability to transform into Mega Man. Subverted, though; from their point of view, their heroes are historical, rather than fictional.
Suspiciously Similar Song: ZX Advent's boss theme's guitar line sounds similar to the chiptune line in The Protomen's Due Vendetta. (ZXA came out in 2007 while the Protomen song in question came out in 2003.)
Joke Character: Model a (lowercase) in Advent, which plays like the original Mega Man. Although it does have a small advantage in being short and harder to hit. Also, easier to overlook on this as there are not really times when it would completely alter an area, the shots will go through walls that don't have the ability to reflect bullets.
Just Eat Gilligan: Advent actually demonstrates the Genre Savvy use of this trope. In the Quarry, Grey/Ashe have an encounter with Aile/Vent, and the two get in a fight over what to do with the Model W in its depths. The former finds the Model W fused to a Spidrill and are forced to destroy both. It turns out that destroying the Quarry's Model W was the whole reason Aile/Vent were there in the first place! Unfortunately, destroying it wasn't enough to keep Ouroboros from forming, but you have to give the gang credit for trying.
The Law of Conservation of Detail: Subverted in Advent due to its attempts to avert You All Look Familiar, where pretty much everyone you meet has different designs and personalities, except for the guys in uniform, who still act different. In other words, trying to rely on this trope to see who is important is completely pointless for this game. Though of course, as in all Mega Man games, the only ultimately really important ones are the robot animals/things actively shooting you.
Lethal Joke Form: Chronoforce's form in Advent; it can't move at all on land, but is immune to attacks from attacks from above and its charge shot, the Time Bomb, is quite useful. You can even change form after it's activated.
Giro: Are you going to let some man you don't even know decide your destiny for you? Destiny is not something that is given to us by others. Destiny comes from the concept of "destine," or directing something towards a given end. Be the one doing the directing. Only you can decide your destiny. Aile: Only I can decide my destiny... Giro: Yes. Forget the past. It means nothing. The power you contain within is the key to creating your future.
Then in Advent, after the Quarry mission, she gives this to Grey:
Aile: Only you can decide your own destiny. No matter what anyone says you are. The power you contain within is the key to creating your future. That's what a special person said to me. Grey: My destiny... My future.
After Grey beats Aile and before he goes down to destroy the fallen Model W, we have this:
Aile: Aren't you going to try and stop me? Grey: That's not why I'm here.
And then, when Grey has trouble destroying the Mechaniloid revived by Model W, Aile comes to the rescue and destroying the Mechaniloid. Then we have this exchange:
Grey: Why did you help me? Didn't you come here to kill me? Aile: That isn't why I came here either.
Meaningless Lives: The games has some extra lives scattered in easy-to-reach places. Combined with the save feature (especially since you can have an option to load your saved game if you get a Game Over), it becomes easier to farm extra lives.
Nostalgia Level: Area D in ZX is an homage to the intro stage of Mega Man X1. It's a highway with helicopter minibosses that cause parts of the highway to collapse. And to drive the point home, the only playable biometal at this point is Model X, meaning X is going through the same level again.
One-Letter Name: The Biometals are named as "Model (the first letter of the corresponding character)".
Operation Blank: Serpent's "Project Haven" in the first game, which aims for acquiring the Model W and activating it by feeding it with Cyber-elves "harvested" from the victims of "Maverick raids" that he secretly made himself.
Outside-the-Box Tactic: Advent's final boss has some otherwise hard-to-avoid attacks if not for the fact that transforming into Chronoforce makes you immune to two of them, and another can be easily avoided by using Model H and upward-dashing then hovering over the blue lasers.
Pre-Explosion Glow: All Pseudoroids (as well as Albert) die this way. A carryover from Zero series.
Vent and Aile are pretty much Distaff/Spear Counterparts of each other. Their stories contain slight differences, but they play exactly the same.
The sequel averts this a bit; it introduces minor gameplay changes and divergent backstories depending on which character is selected. Also, Grey is Reploid and Ashe is human, unlike Vent/Aile who are both human. Additionally, bosses (and thus the player, since Model A is a Ditto Fighter) use different attacks depending on which character you choose.
Interestingly, as shown in Grey's intro cutscene, he had these, before they turned into Green Eyes. As Pandora stated, it's because his brainwashing was incomplete, so it's justified.
Red Oni, Blue Oni: Inverted. Vent/Aile, the Blue Mega Man, is a hotheaded and impulsive boy/girl who tends to charge headfirst into situations. Girouette, the Red Mega Man, is his/her Big Brother Mentor who is calm, caring and level-headed.
The Hunters in Advent (who are arguably expys of the Caravaners, also from the Zero series) notably averts this. In fact, they get a Crowning Moment Of Awesome at the beginning of the game for surviving against the resident Psycho for Hire, and even stole a Biometal out from under his nose.
Repeatable Quest: Rose and Huguet will request you to go to Area Lin order to gather some supplies for them. After going to three diferent sections each time, Rose will give you a sub tank. However, you can only obtain two sub-tanks for this and any subsequent attempt only nets a token thank you and a few Energy Crystals.
Retraux: The Mega Man a minigame in ZXA. If you're crazy enough, the 8-bit "Model a" can even be unlocked for the main game.
Schrödinger's Player Character: This extends into both games, as Aile's and Grey's storyline are connected, as are Vent's and Ashe's. There's actually some hints about connections between the two storylines. Both Vent and Aile are shown in one of the ciphers (Aeolus'). Also, in Ashe's storyline, there's a stage that was Grey's intro stage, but is inaccessible, the latter may imply that, if you play as Ashe, Grey dies in the intro stage, and if you play as Grey, Ashe is killed by Prometheus or dies in the Raider's plane crash.
In the first game, it's stated that the Mega Men (the ones who can use Biometals) have the power to either save the world, or destroy it. Also, in Aile's storyline, it's revealed by Serpent that she has the "blood" of Model W's creator (it's also revealed in the next game that all Mega Men have the "blood", which contains the DNA of said creator, Albert.) After she defeats Serpent, she briefly goes into a Heroic BSODover her "heritage", and then Girouette appears to her as a Cyber-Elf, telling Aile that the blood is just blood and that only she controls her destiny.
In the sequel, after the Quarry mission, Aile/Vent gives Grey/Ashe essentially the same lecture.
It's later revealed that this is Prometheus and Pandora's ultimate goal, since Albert modified them to become permanently Megamerged, and they're destined to fight other Mega Men. They can't escape that destiny (possibly because Their Days Have Been Numbered by Albert), so they exact revenge on Albert by killing him and trying to hasten the "destiny of destruction". Unfortunately, they become Albert's Unwitting Pawns just as they reach their goal...
Shaggy Dog Story: Pretty much the entire first game. Those biometals you retrieved from the pseudoroids? Stolen over the Time Skip and given to new enemies. The entire conflict with Serpent? Just a single part of the real Big Bad's game. That Model W you destroyed? It just broke into several large pieces, all of which are recovered by the bad guys. Oh, and it's also only one of several dozen or possibly hundreds of Model W's scattered across the world.
Whenever the two are fought together, Prometheus and Pandora share a life bar. Whereas each of them alone has 2 layers of life bars, them combined has just 3. In the first game they just attack alternately, while in the second they get Combination Attacks.
In Advent, Argoyle and Ugoyle, when fought, initially appear to have single health bar. However, when you activate Model H and use it to Enemy Scan them, you'll see that each of them has their own health bar.
Some of the Pseudoroids have an uncanny resemblence to other characters. Fistleo's resemblence to Akuma has not gone unnoticed by many fans. Likewise, Hedgeshock/Tesrat looks like the robotic spawn of Sonic the Hedgehog and Pikachu.
The Sage Trinity are all named after the doctors from the classic series (Albert Wily, Thomas Light, Mikhail Cossack), though whether they have any actual relation to the characters is unknown. Interestingly while Wily's expy is traitorous and evil, so is Light's, as revealed in ZXA's secret ending.
If you select Ashe as the hero, Vent will appear in her storyline. Vent is a french name and read as "Van" (ヴァン). Thus, Vaan and Ashe, is the logical conclusion.
This page contains tons of Shout Outs for this series.
Spread Shot: Quite a few that are player-usable in Advent. Buckfire's flaming arrows and Hedgeshock's Charged Attack sparks are of the regular variety, while Rospark's thorns and Model P's shurikens are Spray Bursts.
Superhuman Transfusion: It's revealed in Advent that in order to be able to Megamerge, the "Chosen Ones" needs to be infused with Albert's blood, which contains his DNA, which is the key for Megamerging. It can be argued that the DNA is "datafied" as humans and reploids have machine parts. Not entirely played straight, but it's still there.
Super Mode: The Overdrive Invoke System in the first game. When activated (indicated by an aura), you can assign elemental affinities to your normal attacks (except for Model PX, which enables you to phase through enemies while dashing). Your weapon energy will be consumed slowly while it's activated, and the Overdrive mode will stop if the energy is depleted, or if you get hit. You can also deactivate it manually.
Talking Is a Free Action: The Pseudoroid bosses has a time to talk to the heroes before exploding. Even if they've been cut in half.
Talking Weapon: The Biometals are all qualify, except for Model W and Model O. Oddly enough, Models H, F, L and P becomes The Voiceless in the sequel, but that may be justified by them having evil users.
The Stinger: ZXA has one what reveals that the enemy Mega Men are Not Quite Dead and Master Thomas is not as benevolent as he appears.
Theme Music Power-Up: In the first game, after a little lecture from the 6 Biometals, you get a brief moment of your protagonist's bright idealism, accompanied by Green Grass Gradation (the very upbeat and optimistic Area A music from the very beginning of the game), before commencing the final battle.
Meanwhile, Vent means "wind", Aile means "wing", and Girouette means "weather vane", all in French. Prairie means "meadow", and the operators in the first game have Floral Theme Naming in French (Gardénia, Tulip, and Marguerite). Fleuve means "river" and most of the Guardians' member are named after fishes, also in French. Everything Sounds Sexier in French, apparently.
Jumping from the above two, there's a "earth vs sky" theme within the good guys and the bad guys. Discounting Serpent, of course; but since he was formerly a good guy (a former Guardian member), this still sticks.
Throw The Mook At Them: ZX Advent: A partial example - Hedgeshock can summon robot mouse flunkies. He can normally be hurt by anything, but there's an achievement for using nothing but the mouse flunkies to hurt her - by knocking them at her with the right powerup.
Title Drop: The name "Model ZX" is referenced during the Slither Inc's invasion to the Guardian HQ:
Subverted by the player characters of the first game; the first transformations into the Model X and Model A Mega Men don't take as long as they seem to, as the camera merely focuses on different parts of the body in separate shots - one could argue it's all happening at the same time. The first transformation into the Model ZX Mega Man does take a while, though presumably because of the bodily strain and the energy being released, which vapourises all of the enemies about to shoot Vent/Aile. However, during gameplay, Mega-merging still takes less than a second.
Subverted also by Serpent, who transforms in identical fashion to the hero's in-game transformation, and also by the four enemy Mega Men of Advent, who do take a few seconds, but release powerful phenomena when they do so, which protect and obscure them (respectively: surrounded by whirlwinds, engulfed in flames, encased in ice, wrapped in shadows) and are ready to go immediately afterwards.
Played very straight, however, by Vent/Aile in Advent (when they're met as enemies initially), whose transformations are ludicrously over-the-top and expository, especially Aile's. Also done by Albert, who initially blows away the walls and ceiling, but otherwise floats in the air while his transformation completes itself. Both instances take a very long time to complete, and in both cases, Grey/Ashe just stand and watch.
Transformation Sequence: Vent and Aile in the first game get two for each, one for Model X and another for Model ZX. The second game turn this Up to Eleven, for Vent, Aile, Grey, and Ashe. Most notably Aile, whose transformation seems to be a Shout-Out to typical Magical Girl transformations. Hers can take about a minute and a half.
The Enemy Mega Men also have them, though they don't get animated cutscenes.
Prairie: Aile. I know it's a little late for this, but... I'm so sorry that I didn't tell you about Giro and his mission to watch over you. Please believe me when I say that we didn't want to deceive you. Giro's face always lit up so much when he talked about you... Giro... He loved you very much. Aile: Prairie, did you have feelings for him? Prairie: W-what!? Aile: Hahaha! Maybe Giroresemblessomeone you cared about. Every time you talk about him, you look so happy. Don't worry, I won't hold it against you if you did like him. It's thanks to all of you that I'm finally able to fight for what's important. Prairie: Aile...
Shipper on Deck: From the dialogue above, they seem to ship each other with Giro.
Tron Lines: When Vent/Aile transforms into Mega Man ZX during a cutscene, intricate green lines will appear in the head crystal while red lines will appear over the black body suit.
You ALL Look Familiar: Advent not only averts this trope (except for the hunters when in uniform, and that's kinda justified), but Inti Creates went the extra mile and made almost every NPC character look completely different, and even gave them all amazingly elaborate designs. Yes, even the ones who have no importance whatsoever besides talking to you.
You Killed My Father: One of the Bosses in the first game is revealed to be behind the attack that took the life of Vent/Aile's parent(s).
