Also known by its full name, ''Cyber Troopers Virtual-ON'' is a fast-paced [[MechaGame mecha]] {{fighting game}} by Creator/{{Sega}}. Most of the games' [[HumongousMecha mecha]] designs are by Hajime Katoki, one of the more famous mecha designers for many ''Franchise/{{Gundam}}'' series.

'''''Cyber Troopers Virtual-ON: Operation Moongate''''' (1995), also known as ''VOOM'' or ''OMG'' for short, was first released in the arcades on Sega's [=Model2=] hardware. The arcade machine is a large double sit-down cabinet with a distinctive twin-stick control set. The story has it that [[TwentyMinutesIntoTheFuture in the future]] a series of malfunctions has caused a computer on the Moon armed with a [[EarthShatteringKaboom planet-destroying]] [[WaveMotionGun cannon]] to go rogue. In an attempt to raise the forces to fight this menace, the government sends a number of remote operational terminals into the past, in the hopes that someone (such as [[NoFourthWall you, the reader]]) would have the skills to pilot a [[AMechByAnyOtherName Virtuaroid]] into the moon-base and stop the rogue computer.

It was given a UsefulNotes/SegaSaturn release in 1996, which stripped down the visuals from the arcade version, but added a versus mode; and a Windows PC release followed later in 1997, which by default settings stripped down the frame-rate, but the settings can adjusted match the arcade version or better. The game later received an UpdatedRerelease for the UsefulNotes/PlayStation2 as part of the ''Sega Ages 2500'' line of re-releases (which unfortunately, [[NoExportForYou stayed in Japan]]) on October 30th, 2007. The [=PlayStation=] 2 version is considered the best release yet, as it contains several new features not present in the previous ports, as well as better graphics, crisper sound quality, new extra modes (including one where you can play as the final boss), and a new BonusBoss in the form of the original [[FemBot Fei]]-[[RobotGirl Yen]], which is permanently in [[SuperMode Hyper Mode]] without the health loss and can only be accessed if you beat the first eight Virtuaroids (nine if you fought Jaguarandi) in under nine minutes.

It can still be found in many arcades today, so they might still need our help. What are you waiting for? Get cracking! Your future grandchildren are depending on you! But if finding an arcade machine is too hard, or the Saturn and [=PlayStation=] 2 versions are too expensive, Sega has re-released the game as part of the SEGA Model 2 Collection for UsefulNotes/XBox360 and UsefulNotes/PlayStation3...[[NoExportForYou in Japan]]. [[FromBadToWorse With no plans for a worldwide release]].

'''''Cyber Troopers Virtual-ON: Oratorio Tangram''''' (1999) is the sequel to ''Operation Moongate'', which reveals that the whole mess on the Moon was just a distraction from a splinter group within a powerful [[MegaCorp mega-corporation]] to allow them to break away from their parent company. Now the two are fighting over several mecha plants in the hope of finding the missing Tangram, a super-computer that is said to have the power to [[RealityWarper alter reality]]. Strangely enough, ''Oratorio Tangram'' is very rare in many places; for example, some reports that only two arcade machines were ever shipped to the United States. It had a much wider release for the UsefulNotes/SegaDreamcast, and even without the twin sticks (even though they existed, [[RevenueEnhancingDevices but would burn a huge hole in your wallet]]) it is still a very fun game. ''[[{{Portmanteau}} Oratan]]'' is widely considered to be the best of the series and by far the most popular. It also added more depth into the previous game's mechanics, better gameplay balance, and a slew of new Virtuaroids to chose from.

''Oratorio Tangram'' comes in four flavors: Ver.5.2 was the first release on the SEGA [=Model3=]; Ver.5.4, which updated the interface and fixed many bugs of the first release; Ver.5.45 for the Sega Dreamcast, which was a port of Ver.5.4 with extra arenas from ''Operation Moongate''[[labelnote:*]](the Japanese version also had a color and emblem customization feature, which could be also be used on Ver.5.66)[[/labelnote]]; and finally Ver.5.66 for the arcade, which featured three new Virtuaroid variants and all the extra stages from the Dreamcast version. Ver.5.66 was also switched the software to the NAOMI board used in many Sega games today which updated the sound and graphic quality. On April 29th, 2009, an HD port of Ver.5.66 was released to Xbox Live Arcade world-wide for 1,200 Microsoft Points, featuring a color-edit mode, online multiplayer, tutorials, and the ability to customize your control scheme, but lacks the local split-screen versus mode of the Dreamcast port.

'''''Cyber Troopers Virtual-ON: FORCE''''' (2001), [[CodeName code-named]] [=VO4=], is the series' third installment debuting on the Sega Hikaru hardware. The action was slower than in ''Oratorio Tangram'' (although this was justified in the story that a reaction on the planet Mars made the non-native-built mecha move slower), but featured 2-on-2, allowing up to four-players simultaneously. The game is considered a [[TheyChangedItNowItSucks step back]] from ''Oratan'' and was not well-received. Not to mention there's also a much smaller variety of Virtuaroids to choose from. To compensate for this, they gave the Virtuaroids ''several'' different variants, but only to make the game even more confusing and annoying. On December 21st, 2010, the game received an {{Xbox 360}} release like ''Oratorio Tangram'' did. However, it was released only in Japan as a retail game but the game is [[RegionCoding region-free]]. It includes a brand-new mission mode that's more-or-less ''Virtual-ON: MARZ''[='=]s campaign stripped of a storyline.

There is also a ''MEMORIAL BOX 15'' [[LimitedSpecialCollectorsUltimateEdition premium edition]] to commemorate the series' [[MilestoneCelebration 15th anniversary]]. This package included an artbook that chronicles the entire ''Virtual-ON'' series, a 6-CD soundtrack that spans from ''Operation Moongate'' to ''MARZ'', and two bouncy rubber balls resembling Tangram's eyes. Pre-orders and the premium edition of ''FORCE'' also apparently includes a bonus {{downloadable content}} code that allows players to [[BreastExpansion enhance the bust-size]] of Fei-Yen and Angelan. [[NotMakingThisUpDisclaimer If only we were kidding]]...

'''''Cyber Troopers Virtual-ON: MARZ''''' (2003) for the [=PlayStation=] 2, being an OddballInTheSeries, is essentially a single-player focused version of ''FORCE''. While including a HackAndSlash-style story mode which fleshes out the nature of the ''Virtual-ON'' universe, ''MARZ'' unfortunately stripped down the gameplay even further in several aspects (especially thanks to limitations of the [=PlayStation=] 2 hardware), causing fans of the earlier three entries in the series to [[FanonDiscontinuity completely disown this game]]. The series made a notable appearance in ''[[VideoGame/SuperRobotWarsAlpha Super Robot Wars Alpha 3]]'', with JackOfAllStats Temjin (strangely piloted by the MissionControl character from ''MARZ''), RobotGirl Fei-Yen the Knight (piloted by the second MissionControl character from ''MARZ'' and the Fei-Yen series' supposed creator) and AceCustom Virtuaroid Apharmd the Hatter (piloted by the HotBlooded Sergeant Hatter) as playable characters. They also appear in ''VideoGame/SuperRobotWarsK'' for the NintendoDS, which actually incorporates ''MARZ''[='=]s story. ''Virtual-ON: MARZ'' has been re-released exclusively in Japan on UsefulNotes/PlayStationNetwork on March 2013.

See also G.rev's ''VideoGame/SenkoNoRonde'', a 2D bullet-hell shooter-meets-mecha fighter that shares similar gameplay elements to ''Virtual-ON''.

It possesses a SpiritualSequel in ''VideoGame/BorderBreak,'' a networked 3D arcade mecha shooter featuring 10-unit mecha battles.

* AssKicksYou: Fei-Yen Kn from ''Oratorio Tangram'' has close-range move where she hits you with her metallic rear-end.
* AttackDrone: The Bal series. Deconstructed in a way; the series require a lot of manipulation and, because of this, are ''really'' hard for most people to use and demonstrates exactly how complicated the {{Attack Drone}}s can be for a human player; [[TheComputerIsACheatingBastard the computer, on the other hand]]...
** Bal-Bas-Bow's funnels and arms cannot be controlled by the player, making him really vulnerable to enemy attacks once they're deployed and shooting the wrong side of the arena.
* AttackItsWeakPoint: How to beat Z-Gradt from ''Operation Moongate'', and also Bradtos and Tangram from ''Oratorio Tangram''.
* AwesomeButImpractical: Most of the [[{{Limit Break}} special moves]].

* {{BFG}}: Temjin's Mult-purpose Beam Launcher, Raiden has shoulder-mounted beam cannons that were originally the main guns of battleships, Grys-Vok can launch nukes, et cetera.
** In ''Operation Moongate'', [[FinalBoss Z-Gradt]] has one. It has a barrel diameter that is about the size of Raiden.
* BigDamnHeroes: Sgt. Hatter specializes in this.
* BittersweetEnding: [[spoiler:The ending of ''Operation Moongate'' for ''every'' Virtuaroid ([[AvertedTrope except]] [[HappyEnding Fei-Yen]]) gets one. The last few seconds of the ending shows your VR completely wrecked beyond repair with a limb or two missing and drifting in outer space. What does Fei-Yen get? She slowly floats from space, completely unharmed and protected by a barrier.]]
** [[spoiler:But when you rotate your controller clockwise during the end credits until the your VR shows up, You'll see a spaceship comes and retrieve the VR, and head back to Earth. So it's less bittersweet.]]
* BlindIdiotTranslation: ''MARZ''[='=]s story mode, complete with ridiculously shoddy voice-overs.
* BloodKnight: Gil in ''MARZ''.
* BonusBoss: The original Fei-Yen from the [=PlayStation=] 2 version of ''Operation Moongate'', if you can get to the final stage in under nine minutes.
* BreastExpansion: Did you pre-order your copy of ''Virtual-ON: FORCE''? Here's a [[DownloadableContent redeemable code]] that lets you enhance the chest size of your Fei-Yen and Angelan from an [[UsefulNotes/{{Pettanko}} A-cup]] to a [[BoobsOfSteel DD-cup]] as bonus!
* TheBrute: The SHBVD Raidens in ''MARZ''.
* ChainsawGood: Vox Jane.
* ChestBlaster: Some of the Virtuaroid's center weapon like Fei-Yen's Heart-beam.
* ChildProdigy: Lilin Plajina, developer of LLN series was just a little girl when she built the original Fei-Yen.
* TheComputerIsACheatingBastard: It's been noted that while the [[AttackDrone Bal]] series are generally very difficult to play with for players, but the computer always seems to know how to abuse them ''just'' right.
* ComputerVoice: The announcer throughout the series.
* CoolSword: The Fei-Yen series' rapier, although the Temjim series' [[ImpossiblyCoolWeapon M.P.B.L.]] is arguably [[RuleOfCool the coolest]].
* {{Cosplay}}: Fei-yen, which has had several different outfits over the games and even more outside of them. Some people go a step further, such as [[http://daitrombe.net/image/show/20680 this]]. The [[Franchise/LyricalNanoha Nanoha]] one is particularly fitting since it can be called "[[StealthPun Fei-Yen with Raging Heart]]".
** And now an official CrossOver with {{Vocaloid}}'s Miku Hatsune as of [[{{Doujinshi}} Comiket 80]], [[http://www.oratan.com/forum/viewtopic.php?f=4&t=518 courtesy]] of Sega.
*** Which eventually appeared in ''VideoGame/SuperRobotWars''. [[TheUnexpected Really]].
* CrouchingMoronHiddenBadass: Some of the Virtuaroids with less than favorable stats.
* CycleOfHurting: ''Operation Moongate'' Apharmd's tonfa's. Ouch. Some other Virtuaroid special moves also come to mind. Some normal close-combat attacks can also do this, and not always from [[CrouchingMoronHiddenBadass the Virtuaroids you expect it from]].
* DaChief: [[EveryoneCallsHimBarkeep MARZ Chief]], who relays mission instructions to the player in ''MARZ''. In ''Super Robot Wars'', he's {{retcon}}ned into piloting Temjin himself (and when asked for his name, he simply that "Chief" is good enough).
* DeathInAllDirections: In some fights. Jaguarandi also does this upon you.
* DeathFromAbove: Grys-Vok's special move in ''Oratorio Tangram'' fires a mini-nuke towards the air and... [[PainfullySlowProjectile it takes while for it to fall]].
* DeathRay: Z-Gradt's cannon.
* {{Deconstruction}}: Ultimately one toward fighting game genre as a whole.
* DropTheHammer: Dorkas, as well as his {{expy}} Vox Joe have mace-arms.
* DualBoss: Everywhere in ''MARZ''.
* DualModeUnit: Every Virtuaroid is one, as they can switch (automatically) between long-range and close-combat mode.
* DuelToTheDeath: Every fight is one in ''Operation Moongate''.
* DynamicEntry: Apharmd series' diving kick/tackle. Hatter calls his version "[[GratuitousEnglish Dramatic the Hatter]]".
* EnergyWeapons
* {{Expy}}: The Vox series in ''FORCE'' and ''MARZ'', which start by copying all the Heavy [=VRs=] of the previous games except for Raiden.
** Fei-Yen is often compared to Franchise/SailorMoon. Her heart motif is also identical to that of [[Franchise/SonicTheHedgehog Amy Rose]].
** The Angelans are compared to [[Manga/AhMyGoddess Belldandy]] and Guarayakha are usually compared to [[Manga/CardcaptorSakura Sakura Kinomoto]].
** Created by Hajime Katoki, Temjin resembles a Franchise/{{Gundam}} a lot. It also does a VictoryPose that is the same as the iconic pose of [[Anime/MobileSuitGundam RX-78-2]]. It also runs like Sonic the Hedgehog.
*** In some way, the White Knight resembles a [[Anime/MobileSuitGundamCharsCounterattack Hi-Nu Gundam]] by its look.
*** Who are we kidding? [[VideoGame/SuperRobotWarsAlpha Temjin is R-1, Raiden is R-2, and Fei-Yen is R-3.]] Too bad Virtuaroids can't [[CombiningMecha combine]].
** Raiden resembles [[Anime/MobileSuitGundam Doms]], and was very likely inspired Tieria's Virtue and Seravee in ''Anime/MobileSuitGundam00''.
** The Viper series are compared to the Variable Fighters in ''[[Anime/SuperDimensionFortressMacross Macross]]'', and their LimitBreak is a direct homage to Kamille's wave rider crash in ''Anime/MobileSuitZetaGundam''.
** Kagekiyo is strikingly similar to the Musha Gundam concept.
* ExtremeGraphicalRepresentation: When you fight Tangram.
* FaceHeelTurn: Sgt. Hatter, who runs off half-cocked when he gets sick of the Chief keeping secrets from him, only to turn up later to challenge the player, having not learned of the ConspiracyRedemption and still thinking that ''MARZ'' is in the wrong. If the player runs low on health during the second to last stage, Hatter reappears in a BigDamnHeroes moment, having pulled a HeelFaceTurn.
* {{Fanservice}}: The later models of Fei-Yen. These also feature [[BreastExpansion various breast plate sizes]] in a rare mecha version of FormFittingWardrobe, shared with Angelan. This is explicitly pointed out in one of the CG artbooks included with one of Hasegawa's 1:100 Fei-Yen model kits.
** As of May 31st, 2011, immortalized [[{{Pun}} in the flesh]] in Hasegawa's newest limited release model kit: the TF-12 B/C+ "Fei Yen with Blue Heart/Panic Heart+ [{{Fetish}}]" (yes, "fetish" is actually part of the kit's name). It includes decals for the Flesh Refoe color scheme, parts for the various chest variants, the bigger ass of the G65-model, and Commander Model headwear, as shown in [[http://static.tvtropes.org/pmwiki/pub/images/news2011040802_916.gif this image]].
* FemBot: The Fei-Yen and Angelan series, [[TokenMiniMoe Guarayakha]], the Rose Sisters.
* FinalBoss: [[WeaponsofMassDestruction Z-Gradt]] (or [[TrueFinalBoss the original Fei-Yen]]) in ''Operation Moongate'', [[GeniusLoci Tangram]] in ''Oratorio Tangram'', [[DualBoss Ajim and Guerlain]] in ''Force'', and Tangram [[RecurringBoss again]] in ''MARZ''.
* FragileSpeedster: In ''Oratorio Tangram'', Raiden's special move lets him [[ShedArmorGainSpeed take off his armor]] to became ''[[UpToEleven WAY]]'' faster than both Fei-Yen Kn ''and'' Viper-II. The downside: [[CastFromHitPoints it loses more than 90% of his life gauge]] and his V-Armor goes to straight to 0%.
* FunWithAcronyms: The Virtuaroids' body codes. For example: the "MBV" in Temjin's body code in ''Operation Moongate'' stands for "Main Battle Virtuaroid".
** M.S.B.S. stands for "Mind Shift Battle System".
** [[Creator/{{Sega}} Sentinel Electronics / General Aerodyne]]
** SHBVD stands for Special Heavy Battle Virtuaroid Division
* GameBreakingBug: In the PC version of ''Operation Moongate'', running head on into Belgdor can cause your mech to get stuck ''in'' Belgdor. This changes your screen to entirely light blue, and the round never ends because you can't hit Belgdor and Belgdor cannot hit you and the timer breaks.
** There's also a bug that causes the game to crash upon seeing the continue screen on newer computers, but oddly enough, only Fei-Yen's continue screen doesn't cause the game to crash.
* GlassCannon: the Belgdor, which possesses reliable firepower, long range homing missiles as a primary weapon, is one stiff breeze away from being blown off its feet and knocked down, leaving it vulnerable to even more damage.
* GratuitousEnglish: The infamous "[[/folder]]

[[folder: Get Ready! ]]
" message, and the announcers in general. There's also the endings of ''Oratorio Tangram'' and ''FORCE'', which give a little eulogy for your mech.
** For the curious, they are mangled lyrics to the songs "Everyone Everywhere" and "Just For A Moment", respectively.
*** The mangled lyrics at the end of ''FORCE'' (ending with the phrase 'What more can be said?') originally came from the King Crimson song "Model Man".
** Sgt. Hatter loves using such phrases as "YES!", "COME ON!", and "CONGRATULATION!"
*** ''Super Robot Wars'' adds "ROLLING STAAARRT~!" to his repertoire as a ShoutOut to ''VideoGame/DaytonaUSA''.
* GoldenSuperMode: Fei-Yen's CriticalStatusBuff.
* GunsAkimbo: Apharmd the Battler in ''Oratorio Tangram''. Of course, since it has tonfas built into it's arms, so it also doubles as DualWielding.
* HotBlooded: Sgt. Hatter.
* TheGrimReaper: The Specineff series, complete with a SinisterScythe.
* ImpossiblyCoolWeapon: Temjim's M.P.B.L., its a {{BFG}}, {{BFS}}, and later a WaveMotionGun in one!
** Guarayakha also fit this too.
* [[InfinityPlusOneSword Infinity Plus One Virtuaroid]]: The VR-747 a8 Temjin in ''MARZ''. It's the fastest of all the playable virtuaroids, controls like Oratorio Tangram virtuaroids, very durable, and deals lots of damage. It's unlocked by beating the game on [[NintendoHard Ulti]][[HarderThanHard mate]], in which by then you have other virtuaroids to complete this difficulty with.
* InterfaceScrew: Happens twice in ''MARZ''[='=]s Story Mode.
* JackOfAllStats: The Temjin series.
* JokeCharacter: The completely useless Vox variants Lee and Loo. Lee has nothing but a weak gun. Loo only has a set of missles that have been described as "About as damaging as throwing a toilet paper roll at somebody".
** From ''Oratorio Tangram'' Ver.5.66, we have the 10/80 Special. It's basically a mass-produced Temjin that plays like the original from ''Operation Moongate''. The pros? It has much better control, and is faster than the original. The cons? It cannot air-dash, lacks special moves except the Gliding Ram, and has much weaker attacks.
* KickThemWhileTheyAreDown: In the later games since ''Oratorio Tangram'', you can perform an attack while the opponent is down.
* KillerRobot: Jaguarandi, Z-Gradt, and Bradtos.
* LagCancel: Players can cancel jumps and attacks. If timed rightly, this can go from saving a token to feed the arcade machine, to completely running riot over enemy Virtuaroids.
* LaserBlade: Some Virtuaroids have two.
* LightningBruiser: The Temjin a8 from ''MARZ''.
** Argurably, the Viper series can be considered as this, too.
* LimitBreak: Every Virtuaroid's special move, although most of them aren't very practical.
* MacrossMissileMassacre: Grys-Vok and assorted descendants.
* MadScientist: Dr. Yzerman created Kagekiyo by trapping human souls in a Virtuaroid.
** He is also responsible for the creation of the Viper series, infamous for their [[LimitBreak SLC (She's Lost Control) charge]]. And Specineff series which has device feed on the pilot's negative emotions.
* MagicalGirl: The Angelan series as well as Guarayakha are rather blatantly patterned after them, right down to the cutesy, magic-style attacks.
* MagicalGirlWarrior: Fei-Yen, and she fights with ThePowerOfLove!
* MechaExpansionPack: Grys-Vok, Stein-Vok, and the Vox series are all basically one mech (pretty much the Vox Lee mentioned above) with various weapon combinations mounted on its back and sides.
* MegaCorp: The DN Group and its descendants DNA and RNA.
%%* MightyGlacier: Dorkas and its descendants, Dordray and Vox.
* NiceHat: Hatter, [[CaptainObvious obviously]]. He even uses it as a PrecisionGuidedBoomerang.
* NiceJobBreakingItHero: Lilin Plajina tried to get rid of Jaguarandi, consider as an annoying "bug" in M.S.B.S. network at time, by using Guarayakha to contain it. While it seem to work, now Jaguarandi can manifest itself in physical world using Guarayakha and its replica.
* NoFourthWall / IKnowMortalKombat: Apparently, the original arcade game itself is actually a control module sent from the future. You playing it is actually participating in the battles.
** Unfortunately, ''MARZ'' broke this essential part that made the series fun.
* NoNameGiven: Temjin never tells his name in either ''Super Robot Wars'' and lets other call him ''Chief''.
* NonstandardGameOver: Have more health than Z-Gradt or Tangram when time's up? Congratulations, you've just let the planet-killing superweapon/reality-destroying supercomputer win.
* OddballInTheSeries: ''MARZ'' counts as this. It is a HackAndSlash-style action adventure game with ''VideoGame/SengokuBasara'' elements, rather than simply a one-on-one fighting game, though there's more one-on-one matches too.
* QuirkyMiniBossSquad: The [[AmazonBrigade Three Rose Sisters]] in ''MARZ''.
* PaintItBlack: After pulling his FaceHeelTurn, Sgt. Hatter has his Apharmd repainted from the ''MARZ'' standard blue/white coloring to a new dark blue/red one.
** The [[EvilCounterpart Shadow VRs]].
* PantyShot: It's not hard to see up Fei-Yen's skirt, although players will be surprised that Fei-Yen Kn from ''Oratorio Tangram'' [[GoingCommando is technically not wearing panties]].
* PlayboyBunny: A rare FemBot example; Fei-Yen and Angelan were built into one with [[http://vo-ot360.sega.jp/dl_image/otwp05_1920.jpg this wallpaper]], courtesy of Katoki himself. Shame that they aren't playable though.
* PlayerAndProtagonistIntegration: You are ''you'' in the single-player campaign in every series, but in ''MARZ'', an Advisor protagonist is added as your superior.
* PinkGirlBlueBoy: Fei-Yen is pink, Temjim is blue.
** Since ''Virtual-ON: FORCE'', we also now have Guerlain's pink and Ajim's blue.
* PowerCrystal: The Virtuaroids are powered by this, and Ajim (and his DistaffCounterpart Guerlain) is a [[SinisterGeometry V-crystal in living form]].
* PowerGivesYouWings: Angelan's special move, she becomes slightly more faster and powerful temporary.
* RazorWind: Several weapons used by the Virtuaroids are capable of launching energy variations of this.
* {{Roboteching}}: When firing a weapon lock-on to its target.
* RobotMaid: The later [[{{NinjaMaid}} Fei-Yen]] series starting with ''FORCE'', complete with [[{{Maid}} plateau-weapon and proper clothing]].
* [[CatGirl Robotic Cat Girl]]: Fei-Yen the Tiger in ''Oratorio Tangram''. Although her ears are actually heart-shaped, she has tiger stripes and a tail.
* RocketPunch: Several members of the Vox series can launch their melee weapon-equipped arms at enemies.
** The Bal-series from ''Oratorio Tangram'' can perform one, too.
* RuleThirtyFour: Yes. It applies here too. And no, it isn't MoeAnthropomorphism (although that also exists). How? YouDontWantToKnow. TakeOurWordForIt.
** Katoki himself indulges into it, as seen above.
* SecretLevel: If you take too much time beating the first five enemies in ''Operation Moongate'', you end up at [[SecretCharacter Jaguarandi]].
* ShedArmorGainSpeed: Raiden can sacrifice 90% of its health and all of its V-Armor in exchange for a massive boost to speed.
* ShoutOut: In ''Oratorio Tangram'', the dialogue said by the computer voice is taken from the lyrics Republic's ''Everyone, Everywhere''. In ''FORCE'', the Congratulatory Address is a heavily modified version of the chorus to Ultravox's ''Just For a Moment''.
** The model kits for the ''Oratan'' Virtuaroids are actually made by the same company who made ''VideoGame/{{Medabots}}'' model kits.
* ShowsDamage: In the first two games, the Virtuaroids will loose armor parts as they get more damage. This no longer happened after FORCE.
* ShoulderCannon: Raiden and certain variants of Apharmd and Temjin. See also Belgdor and its Vok-variant descendants.
* SkySurfing: Temjin's Gliding Ram attack. [[AwesomeYetPractical Not only does it look cool, it hits HARD.]]
* StabTheSky: Often after performing a [[NoDamageRun Perfect]] victory.
* SuperCuteSuperPowers: The Fei-Yen series of Virtuaroids are HumongousMecha modeled after a MagicalGirl with a ChestBlaster that fires a burst shaped like a heart. According to the backstory, the designers wanted a regular beam, but the SentientPhlebotinum kept turning it back into a heart.
* SuperDeformed: The [=PlayStation=] 2 re-release of ''Operation Moongate'' features a Chibi-version Mode that make all the Virtuaroids [[FunSize cute and tiny]].
* SuperMode: Normally when the Fei-Yen series TurnsRed, and it's a special move for her in ''Oratorio Tangram'', at [[CastFromHitPoints a huge expense her life]] though.
* SurprisinglyHappyEnding: In ''Oratorio Tangram'', [[spoiler:what started out to be another BittersweetEnding just like its predecessor (and this time with no barrier to save Fei-Yen), other units of your selected Virtuaroid swoops in to save you and carry you to the aircraft carrier. Though Ajin 'rescues' himself as he's joined by his other units.]]
** [[spoiler:For Fei-Yen in said game, she gets saved by Angelan and the same applies vice-versa.]]
* SuperPrototype: The original Fei Yen is much more powerful than her production model. Justified since she's sentient and eventually runaway from Lilin's lab.
* SuperRobotGenre: Truthfully, the game kind of blurs the line between Super and Real Robot. Some mecha, like Temjin and the Viper series, are very much like Real Robots, but then you have the ''Franchise/SailorMoon''-like Fei-Yen and Angelan, which can summon giant ice dragons and send them to attack you.
* VideoGame/SuperRobotWars: [=MARZ=] appears in ''VideoGame/SuperRobotWarsAlpha 3'' and ''[[VideoGame/SuperRobotWarsK K]]'' (the latter includes its story). ''VideoGame/SuperRobotWarsUX'' includes the Virtuaoid [[TheUnexpected Fei-Yen HD]], which never appeared in the series; it's actually an action figure based off the {{Music/Vocaloid}} {{Crossover}} mentioned above.
* SwordAndGun: Temjin's M.P.B.L. is this combined into one.
* SwordBeam: Nearly every Virtuaroid with a close-combat weapon can use these.
* ThisIsADrill: Dordray, as well as his later [[{{Expy}} expies]] Vox Bob-1 and Bob-2, have arm-mounted drills.
* TransformingMecha: Viper II and its later descendants, which can transform into a [[CoolPlane fighter jet]].
** The Viper II from ''Operation Moongate'' has a LimitBreak very similar to this. Furthermore, when it jumps it extends its wings.
* TriggerHappy: Jaguarandi.
* UnusualEars: Parodied by several Fei-Yen models, especially the "Fei-Yen the ([[LittleBitBeastly animal]])" models.
* WaveMotionGun: The Raiden's iconic shoulder lasers, which were originally mounted on ''battle-cruisers''. [[CaptainObvious Get hit and much pain ensues]].
** It almost [[OneHitKill one-shots]] [[FragileSpeedster Viper-II]]. Of course, that's assuming you're firing the regular standing laser. The dashing and air varieties are significantly weaker.
** Temjim's right-turbo RW attack in ''Oratorio Tangram'' turns his M.P.B.L. into one.
** Z-Gradt's main cannon in the original game can take off at least half of your health.
* WeCanRebuildHim: The continue screen in ''Operation Moongate'' and ''Oratorio Tangram'' save for Fei-Yen and Angelan, who gets the MagicalGirl [[HealingFactor regeneration sequence]]. Also averted for Ajim in ''Oratorio Tangram'', who gets an ascension sequence.
* ZettaiRyouiki: Fei-Yen and Angelan at grade-A with robotic thigh-highs.
