One fine day in Japan, the ''VideoGame/SuperRobotWars'' division of Banpresto pondered the following: "Hey, our HumongousMecha MegaCrossover franchise has developed [[LoadsAndLoadsOfCharacters quite the roster]] of [[OriginalGeneration original characters]]. What say we, instead of paying out the license fees for ''Franchise/{{Gundam}}'', ''Anime/{{Macross}}'', ''Anime/MazingerZ'', ''Manga/GetterRobo'' and the like for this year's game, just build it around our in-house characters and robots instead?"


Thus was born ''Super Robot Wars Original Generation'', released for the GameBoyAdvance. Featuring a couple dozen original pilots created from ''VideoGame/SuperRobotWarsAlpha'' and prior (but strangely no [[Characters/MasouKishin Masou Kishin entries aside from Masaki Andoh, Lune Zoldark and Shu Shirakawa]], although that's all the first ''Alpha'' title ever offered), its plot involves the Divine Crusaders War from ''VideoGame/SuperRobotWars2'' and the initial stages of the Balmar War in ''Alpha'', but without all those other distractions provided by the [[Anime/NeonGenesisEvangelion Angels]], [[Anime/{{Macross}} Zentraedi]], [[Anime/GunBuster Uchuu Kaijuu/STMC]], and so forth (the United Colony Corps plays the role of the [[Anime/MobileSuitGundam Principality of Zeon]]). But wait, you ask: "didn't ''Alpha'' have all sorts of corrupt politicians and enemy pilots to impede our heroes Banpresto hasn't made {{expy}}s of yet?" Well, yes, and they exist ''now'' - a good third or so of the ''Original Generation'' cast is comprised of these sorts of people (and a couple of the heroes, even) created exclusively for these games.

The first installment allows you to play from the perspective of either [[Characters/SuperRobotWarsAlpha Ryusei Date]], a mecha fanboy who ends up getting recuited for a military program developing psychic weapons, or [[Characters/SuperRobotWarsCompact2 Kyosuke Nanbu]], a stoic test pilot who finds himself paired with a rather energetic young woman named [[Characters/SuperRobotWarsCompact2 Excellen Browning]]. Despite the first half of each character's story taking place separately, their stories co-exist simultaneously, with the second half covering the exact same events as the two teams come together, but with a few differences.

Nearly three years and several mainstream [=SRW=] games later, Banpresto wheeled out ''Super Robot Wars Original Generation 2''[[note]]'''Not''' "Dai-2-ji", but literally "Original Generation 2" - we'll get to that below[[/note]] for the Game Boy Advance, with new additions from the interim games. This time, the plot finishes the MidSeasonUpgrade portion of ''Alpha'', introduces the [[Characters/SuperRobotWarsAlpha Machinery Children]] of ''Alpha Gaiden'', as well as part of the story of [[Characters/SuperRobotWarsAlpha Arado Balanga]], and also includes the prologue to the ''Alpha 2'' story of [[Characters/SuperRobotWarsAlpha Ibis Douglas]]. The primary focus of ''Original Generation 2'' is the Einst of ''[[VideoGame/SuperRobotWarsCompact2 Super Robot Wars Compact 2/Impact]]'', the Shadow-Mirror of ''VideoGame/SuperRobotWarsAdvance'', and the Inspectors of ''VideoGame/SuperRobotWars3''. The game also introduces an original plot, combining part of Arado's tale with the story of a character introduced in the first game, as {{tykebomb}} ex-students of a harsh military training school.

But even that wasn't enough, so just before their absorption into Creator/NamcoBandai, Banpresto compiled both games into a VideoGameRemake for the UsefulNotes/PlayStation2 called ''Super Robot Wars OG: Original Generations'' and gave it all the bells and whistles of a full console-sized [=SRW=], plus additional scenarios bridging the original games and a "2.5: Unified Wisdom" scenario based on the semi-sequel {{OVA}}. These additions brought more "[[FanNickname Banpresto Originals]]" and set the stage for ''Super Robot Wars Original Generation Gaiden'', a GaidenGame sequel expanding on the "2.5" mini-plot into an entire story by combining them with the plots of ''VideoGame/SuperRobotWarsCompact3'', ''VideoGame/SuperRobotWarsReversal'' and a few characters from Banpresto's earlier ''The Great Battle'' series on the SuperFamicom.

Then there's the GaidenGame spin-off sub-series ''Super Robot Wars OG Saga''. The first game, ''EndlessFrontier'' for the NintendoDS, is a different beast entirely, since it's a conventional EasternRPG rather than a TurnBasedStrategy, featuring loads of {{expy}}s, an [[ActionCommands action command-based]] combat system revolving around massive juggling combos ([[{{Fanservice}} among]] [[GagBoobs other]] [[HurricaneOfPuns things]]), and [[VideoGame/{{Xenosaga}} KOS-MOS and T-elos]]. For those who played ''VideoGame/NamcoXCapcom'', they get to see Reiji Arisu and Xiaomu again; for those who [[NoExportForYou haven't]], [[MarthDebutedInSmashBros well... now they have]]. It takes place in a group of [[AnotherDimension connected worlds]] called the "[[ThePlace Endless]] [[ExactlyWhatItSaysOnTheTin Frontier]]", with the lives of the inhabitants shaped by the events of ''Original Generation 2''. It's followed by a sequel ''Endless Frontier EXCEED'', which itself has ties to the ending of ''Original Generation Gaiden'', as well as incorporating a couple of characters from main continuity. The third ''OG Saga'' game is ''Masou Kishin: The Lord of Elemental'', a remake of ''VideoGame/SuperRobotWarsGaiden'' (technically the first all-original [=SRW=]) that (re)incorporates its story into ''Original Generation'' canon. It was followed by ''Masou Kishin II: Revelation of Evil God'' and ''Masou Kishin III: Pride of Justice'', the direct sequels to ''The Lord of Elemental''.

The series has gone full-circle with three {{Animated Adaptation}}s: a three-part OVA by Creator/BrainsBase[[note]]''{{Anime/Mazinkaiser}}'' and ''Manga/GetterRobo: Armageddon''[[/note]], whose events were rolled into ''Original Generation Gaiden''. "Divine Wars" [[note]]by Creator/OLMIncorporated, who made ''Anime/ShinkonGattaiGodannar''[[/note]], a re-telling of the first game, and "The Inspector" [[note]]by Creator/AsahiProduction, who [[Anime/RobotRomanceTrilogy assisted]] on [[Anime/TheBigO many]] [[Franchise/{{Gundam}} mecha]] [[Anime/DancougarNova shows]][[/note]], which covers the second game. There are also various manga adaptations, such as "Record of ATX", which goes through the first two games from Kyosuke's point of view.

In August 2011, nearly 7 years after ''Original Generation 2'' was released on the Game Boy Advance, the true non-GaidenGame, non-remake sequel was announced. Entitled ''The Second Super Robot Wars Original Generation''[[note]]That is, "Dai-2-ji", stylized in the way sequels of major continuities like the "Classic Timeline", ''Alpha'' and ''VideoGame/SuperRobotWarsZ'' are done; yes, this created some confusion and bemusement in Japan[[/note]], it is the first [=SRW=] to be released on the UsefulNotes/PlayStation3. The story expands the ''Alpha 2'' plotlines for [[Characters/SuperRobotWarsAlpha Kusuha Mizuha]] and Ibis, as well as concluding the ''MX'' saga. In addition, Joshua Radcliffe and Cliana Rimskaya of ''VideoGame/SuperRobotWarsDestiny'', [[Characters/SuperRobotWarsOriginalGeneration Ariel Org]] of ''Real Robot Regiment'' and [[Characters/SuperRobotWarsOriginalGeneration Ing Egret]] from the ''Alpha 2'' side-story manga ''Lost Children'' are the new entrants into the series. From a mecha standpoint, the [=RyuKoOh=]/[=KoRyuOh=]'s brother machines [=JakuBuOh=]/[=BuJakuOh=] appear for the first time in an [=SRW=] game. The final promotional video featured the rest of the ''Masou Kishin'' cast to facilitate ''VideoGame/SuperRobotWarsEX''. Additionally, the [=RaiOh=] from ''Alpha 3'' appears, yet a villianous AI-controlled SuperPrototype takes it place first, whose objective is the destruction of the other Dynamic General Guardian {{super robot}}s called the ''[[ContinuityNod Jin]][[MythologyGag Rai]]''. [[Characters/SuperRobotWarsAlpha Touma Kanou]], who previously appeared as TheCameo in ''Original Generation Gaiden'', is one of the playable characters. [[DevelopmentHell A year after the announcement]], the game was released on November 29, 2012.

In August 2013, Banpresto announced ''Super Robot Wars Original Generation Infinite Battle'', a 3D FightingGame in a similar style to the ''VideoGame/GundamVsSeries'' and ''AnotherCenturysEpisode'', featuring the ''Original Generation'' cast, released on November 28, 2013. While ''Infinite Battle'' contains no plot to {{continuity}}, the [[LimitedSpecialCollectorsUltimateEdition premium edition]] of ''Infinite Battle'' is bundled with ''Super Robot Wars Original Generation Dark Prison'', a GaidenGame headlined by Shu. These scenarios detail the events of his story from ''EX'' and his behind-the-scenes work when the cast is summoned to La Gias in the ''Second Original Generation''. The contents of his ''EX'' scenario was intended to be in the ''Second Original Generation'', [[WhatCouldHaveBeen but didn't make the cut]]: ''Dark Prison'' rectifies this. Additionally, it serves as a prologue of sorts for [[Characters/SuperRobotWarsAlpha Selena Recital]], who appears with other characters. ''Dark Prison'' is available individually as DownloadableContent in 2014.

In January 2016, Banpresto teased ''Second Original Generation'' sequel ''The Moon Dwellers'', introducing ''VideoGame/SuperRobotWarsJudgment'' into the fray with [[Characters/SuperRobotWarsJudgment Touya Shun]] as the headlining protagonist with [[Characters/SuperRobotWarsJudgment Calvina Coulange]] as supporting. Furthermore, both versions of the hero(ine) from ''VideoGame/SuperRobotWarsGC'' will join the roster: whereas the male "Akimi Akatsuki" keeps the original name, the female is rendered into his [[HalfIdenticalTwins older twin sister]], "Ak''e''mi" (similar to the ''Reversal'' protagonists). In a twist, [[Characters/EndlessFrontier Haken Browning and Aschen Blodel]] from ''Endless Frontier'' will join the roster, using a HumongousMecha-sized version of the game's Gespenst Phantom. ''The Moon Dwellers'' will be simultaneously released on the [=PlayStation=] 3 and the UsefulNotes/PlayStation4, the first [=SRW=] for the latter console. Finally, after years of NoExportForYou, Namco Bandai will localize the [=PlayStation=] 4 version into English for the Southeast Asia region; whether Europe and North America will receive the same treatment remains to be seen.

See here for the [[LoadsAndLoadsOfCharacters massive]] [[SuperRobotWarsCharacterSheet character sheet on all the originals]].
%% Please put all character-related tropes in their respective Characters/SuperRobotWars pages.
!Tropes pertaining to multiple characters and the entirety of ''Super Robot Wars Original Generation'' are:

* AbsentAliens: [[spoiler:All life originated on Earth, even the [[CosmicHorror Einst]]]], which also inverts the AncientAstronauts trope.
* ArtEvolution: [[http://img.photobucket.com/albums/v629/Kuruni/MS-Story/Vault-SRW/rtx-008r.jpg This]] is the Huckebein in ''VideoGame/SuperRobotWars4''; compare it to [[http://img.photobucket.com/albums/v629/Kuruni/MS-Story/Vault-SRW/rtx-008.jpg the current version]].
* TheAce: Aside from characters given a notification for achieving a certain amount of kills becoming "[[ExactlyWhatItSaysOnTheTin aces]]", characters from the elite Aggressors unit have been in combat longer than the rest of the cast. Moreover, in-universe, they're the ones who ''created'' mecha combat.
* AnotherSideAnotherStory: Any release in the ''OG Saga'' line, since their intent is to expand on the happenings of other characters in other settings. ''Dark Prison'' chronicles Shu and his party's activities during the main storyline for the ''Second Original Generation''. One example is Selena, [[Characters/SuperRobotWarsAlpha Albharda]] and [[Characters/SuperRobotWarsOriginalGeneration Yong Gelbana]] [[spoiler:witnessing one of the energy beams fired by [[Characters/SuperRobotWarsAlpha Irui Gan Eden]] towards the moon, which occurs just as the FinalBoss scenario is underway in the ''Second Original Generation''. The players see the blast literally shattering a part of the moon but Elma mentions that the beam "[[{{Foreshadowing}} did not hit any]] [[VideoGame/SuperRobotWarsJudgment man-made structures on the moon.]]"]].
* AttackPatternAlpha: The new mechanic "Maximum Break" in the ''Second Original Generation'' allows a pilot with the "Leadership" pilot skill to initiate an attack with three allied characters, even when none of them have the "Support Attack" pilot skill. It is the ''Original Generation'' close-equivalent to the TRI-Battle System in ''VideoGame/SuperRobotWarsZ''; long story short, MoreDakka ensues.
* {{Badass}}: Most characters, heroic or villanous, adhere to this. Some greatly personify it, whereas one of them is Banpresto's walking embodiment of it. To wit:
** BadassArmy: The Earth Federation Army, the (Neo) Divine Crusaders, the United Colony Corps, the Shadow-Mirror, the [[Characters/SuperRobotWarsCompact3 Shura]] and the [[Characters/SuperRobotWarsOriginalGeneration Gaia Sabers]].
** BadassCrew: The collective crews of the ''Hagane'' and ''Hiryu Custom''. To a smaller extent, the individual ATX Team, SRX Team, Octo Squad, Aggressors, and the ''Dark Prison'' party members.
* BeachEpisode: Present in the games for no reason other than {{Fanservice}}; the ending credits of ''The Inspector'' is one itself. Exemplified in the special edition of ''The Moon Dwellers'' with a dedicated drama CD called "The Beach Dwellers".
* BiggerBad: While this notion was played with in previous games, the events leading up to the ''Second Original Generation'' is manipulated by [[spoiler: [[Characters/SuperRobotWarsAlpha Euzeth Gozzo]], who is using his clones in the multiverse to revive himself. He remembers everything that has happened in the different universes he was in, too]].
* BiggerBad [[BigBadEnsemble Ensemble]]: As of ''Second Original Generation'', there are at least three major threats (that we know of) that have either been simply glimpsed by the heroes or just delayed in their objectives:
** [[Characters/CompatiHeroSeries Dark]] [[MultiversalConqueror Brain]]: Was forced back into whatever dimension he was hiding in, but he's by no means beaten, and is still seeking the 'Twelve Keys'.
** [[Characters/SuperRobotWarsDestiny Perfectio]] [[CosmicHorror The King of Ruin]]: Was sealed out of the OG Dimension thanks to [[spoiler: Chris's and Ventus's HeroicSacrifice,]] but it's unknown if they can hold him permanently. And given his [[EldritchAbomination nature]], killing him outright may be [[CompleteImmortality impossible.]]
** The [[SuperRobotWarsAlpha Balmar]] [[TheEmpire Empire]]: Haven't been seen in force since ''OG1'', but their influence has still been felt with [[spoiler: [[Characters/SuperRobotWarsAlpha Euzeth Gozzo]] being the BiggerBad / TrueFinalBoss]] of ''Second OG'', and the [[Characters/SuperRobotWarsClassic Zuvorg Alliance]] being extremely wary of them. And with the Balmar, there is of course their leader, [[GodOfEvil Kaiser Ephes]] to worry about as well.
* BittersweetEnding: The ''Second Original Generation'' ends with [[spoiler:Irui Gan Eden surviving the destruction of the Nashim Gan Eden, while [[Characters/SuperRobotWarsAlpha Kukuru]] and the [[Characters/SuperRobotWarsOriginalGeneration Garden of Baral]] are destroyed, yet [[Characters/SuperRobotWarsAlpha Son Ganlong]] implies he will return. [[Characters/SuperRobotWarsDestiny Ventus]] and the "Chris" personality of Cliana are sealed away with [[Characters/SuperRobotWarsDestiny Perfectio]], [[Characters/SuperRobotWarsDestiny Glacies]] and Ariel have a limited lifespan remaining and Euzeth drops enough ominious bits that the worst has yet to come (and indeed. Following the Alpha timeline, next in line would be Keisar Ephes)]]. The upside is [[spoiler:[[Characters/SuperRobotWarsClassic Mekibos]] has secured an alliance between humanity and the Zuvorg, which may or may not have consequences in regards to the Ze Balmary Empire, whom the Zuvorg are just as wary of. The Cross Gate left intact acts as a WildCard: it may bring more extraterrestrials/interdimensional travellers looking to conquer Earth, yet it opens the possibility for the Shura, who have previously left in ''Original Generation Gaiden'' on a good note, to return and reinforce the Earthlings. Or possibly, the Elemental Lords of La Gias, who also departed to La Gias to take care of its inner business after Euzzeth has been taken care of (miracle might be required here since the last we see them in ''Coffin of the End'', [[TheMagicGoesAway the Elemental Spirits have left]])]].
* BoringButPractical: Certain equippable weapons, such as the M920 Machine Guns, are quite powerful, have decent range and are usable post-movement with a ton of ammo, cheap to upgrade, and damage isn't degraded on certain terrain.
* BrainwashedAndCrazy: This tends to recur with disturbing frequency throughout the span of the storyline. Among those who went through brainwashing of some manner at some point are [[Characters/SuperRobotWarsOriginalGeneration Tempest Hawker, Shine Hausen, Tenzan Nakajima]] (though he was already [[AxCrazy pretty crazy to begin with]]), Kusuha, Tenzan ''again'', and [[spoiler: [[Characters/SuperRobotWarsAlpha Levi Tolar]]]] in the first game, while [[Characters/SuperRobotWarsAlpha Seolla Schweizer]], [[Characters/SuperRobotWarsOriginalGeneration Ouka Nagisa]], and Excellen get hit with this in the sequel. ''Original Generations'' retools a plotline regarding [[spoiler:[[Characters/SuperRobotWarsAlpha Ingram Prisken]]]] to make it so that ''he'' was suffering from this to an extent. For ''Original Generation Gaiden'', [[Characters/SuperRobotWarsAdvance Lamia Loveless]], [[Characters/SuperRobotWarsOriginalGeneration Shouko Azuma]], and [[Characters/SuperRobotWarsCompact3 Fernando Albark]] get to "join in on the fun". The ''Second Original Generation'' tones this down, as [[Characters/SuperRobotWarsAlpha Brooklyn "Bullet" Luckfield]] doesn't get his brainwashing from ''Alpha 2''; it goes to the [=KoOhKi=], instead. Only Touma per his ''Alpha 3'' scenario (via the LIOH System in the [=RaiOh=]) is hit with this.
* BrickJoke: In ''Alpha 2'', [[Characters/SuperRobotWarsAlpha Robert H. Ohmiya]] comments about outfitting the [=DyGenGuard=] with a Neo Chakram Shooter or G-Impact Stake. It never comes to pass on account of the preferences to its pilot [[Characters/SuperRobotWarsAlphaGaiden Sanger Zonvolt]], but the weapons are obtainable throughout the series provided Sanger and [[Characters/SuperRobotWarsOriginalGeneration Ratsel Feinschemcker]] don't score any kills in their respective units.
* BridgeBunnies: A standout since the first game, being only nameless [=NPCs=] that aren't faceless with ''Original Generations'' giving two portraits for them. ''The Inspector'' highlights them with distinctive faces that one can easily mistake them supporting characters [[note]]One of them looks awfully familiar to one of the Anime/{{Gravion}} BridgeBunnies[[/note]]. Naturally, the ''Hagane'' and ''Hiryu Custom'' come with their own set of this.
* BunnyEarsLawyer: To put it bluntly, EVERY allied character, and a fair majority of the villains are weird, which DOESN'T detract from their piloting abilities.
* CanonImmigrant: Aside from characters moving from [=SRW=]-related manga, anime and drama [=CDs=] into the games, this extends to mecha and certain attacks from machines.
* CanonDiscontinuity: The second half of Kyosuke's route in ''Original Generation'', as a result of StoryBranchFavoritism. Something of an odd case, because even though the sequel follows Ryusei's entire route, Kyosuke's second half drops tons of {{foreshadowing}} as to the plot of ''Original Generation 2'', and lets us know somewhat more of just how much a MagnificentBastard [[spoiler: Ingram]] really was.
** ''Original Generations'' not only [[ContinuityReboot reboots the timeline]], but discontinues the {{True Final Boss}}es being optional, going on the premise they're actually fought.
* CaptainErsatz: Not simply the characters, but this includes the machines, with the most obvious stand-ins are the Huckebeins being Franchise/{{Gundam}}s by another name. Taken up a notch with the mass-produced Huckebein MK II, a faceless machine built in the style of the [[Anime/MobileSuitGundam GM series]]. Similarly, Gespensts are stoutly built mass-produced units rolled out before other mecha in the series and get tons of variants, whose default color is green. Effectively, they are the [[Anime/MobileSuitGundam Zaku]] of ''Original Generation''.
** The Lion series, meanwhile, are similar to the [[Anime/MobileSuitGundamWing Organization of Zodiac]] mecha, not only in their ThemeNaming, but they're highly streamlined, expendable and fielded by a shadowy faction that rises up against the government lead by a grandiose, morally ambiguous visionary. The three most common Lion-types fulfill similar roles (expendable fodder: Lion/Leo; artillery: Barrellion/Tragos; high-speed fliers: Guarlion/Taurus).
** The three main battleships, the ''Hagane'', ''Hiryu Custom'' and ''Kurogane'', are basically [=SRW's=] versions of the [[Anime/UchuuSenkanYamato Yamato]], [[Anime/MartianSuccessorNadesico Nadesico]] and [[Franchise/{{Godzilla}} Gotengo]], respectively.
* ClosingCredits: See BeachEpisode, but episode 17 of ''The Inspector'' breaks tradition by featuring a softer, more romantic song accompanying clips of Kyosuke and Excellen from earlier episodes [[spoiler: because this is the point where Excellen's abducted by the Einst]].
* {{Combination Attack}}s
* CompressedAdaptation: Given the games have a minimum 40 "episodes" in a playthrough, their {{Animated Adaptation}}s, which are 26 episodes long, are inevitably this.
* ConspicuousCG: The enemy mecha in the OVA and every mecha in ''Divine Wars''. ''The Inspector'' uses this for generic mecha and airships.
* ContrivedCoincidence: While it seems like this is based on the idea extraterrestrials flock to Earth within a span of a few years, [[spoiler:Shu drops a revelation in the ''Second Original Generation'' regarding the Granzon's Anti-Matter Annihilation Engine and black hole technology had been, without his knowledge, altering space-time probability within the universe, causing these coincidences to occur more often. In short, all these coincidences occur because they are being ''forced'' to happen. He cancels the effect at the same time he drops this bombshell, but acknowledges it's probably too late for this to change anything]].
* {{Deconstruction}}: The first game did this regarding {{Super Robot}}s. Instead of ultimate machines that run on willpower or some AppliedPhlebotinum, all Earth-developed supers are treated as considerably stronger {{Real Robot}}s that run on feasible Earth technology and dynamics. This is reconstructed in the sequel, with the introduction of the Choukijin. It isn't until the appearance of [[Characters/SuperRobotWarsOriginalGeneration Fighter Roar]] and the Compatible Kaiser do we get classic SuperRobot.
* DerivativeWorks: Includes, but limited to:
** TheAnimeOfTheGame
*** ''Masou Kishin Cybuster'', a 26-episode anime that [[InNameOnly had nothing to do with SRW outside of the titular mech and a few names]]. We... don't talk about it much.
*** ''The Animation'', a three-episode OVA [[{{CanonDiscontinuity}} that used to be]] a sequel to ''Original Generation 2''. Partially incorporated into ''Original Generation Gaiden''.
*** ''Divine Wars'', a re-telling of events depicted in Ryusei's ''Original Generation'' route, with significant changes to the narrative (the absence of Huckebeins being a prime example). Still, minor elements in this anime has been added into continuity.
*** ''The Inspector'', a sequel to ''Divine Wars'' and an adaptation of ''Original Generation 2''
** AudioAdaptation
*** ''Sound Cinema'', a drama CD created as a companion title to the OVA. This side-story involves an attack on the Tesla-Leicht Institute by agents in support of the OVA's BigBad.
*** Two drama [=CDs=] bundled with the ''Endless Frontier'' games: the first tells of a brief, but significant back-story to the Shadow-Mirror, to which a theory is confirmed for one of the characters, while the second follows three individuals from main continuity and explains how they wind up in the ''EXCEED'' sequel.
** [[ComicBookAdaptation Manga Adaptation]]
*** ''Record of ATX'', a side-story manga complement to ''Divine Wars'' and ''The Inspector'', but tells of the events primarily from Kyosuke's perspective.
*** ''OG Chronicles'', a set of side-stories throughout the games primarily to display the on-goings of other characters and events that happened between the games. A few of the stories and characters [[CanonImmigrant have been incorporated into canon]].
*** ''[=RyuKoOh=] Denki'', a story set centuries before ''Original Generation'' regarding the Choukijin and various ancestors of the present day cast. Is used as a frequent MythologyGag in the main series. Re-released in 2011 under the "OG Saga" heading.
** Photo Novel
*** ''Record of Fallin' Deceased X'', a photographic novel akin to ''Manga/GundamSentinel'', this side-story published in Dengeki Hobby magazines features the "Gesterben", a customized mass-produced Gespenst MK II fielded by the eponymous Fallin' Deceased X (FDX) Team. The Gesterben makes its debut in ''Dark Prison''.
* {{Determinator}}: Most villains are dedicated into taking you down; naturally, the heroes are this when they become sufficently pissed.
* DistressedDamsel: At least one in every game, but Kusuha stands out, in contrast to her complete (but still gentle) ActionGirl self in the ''Alpha'' series. To sum it up, it won't be complete if Kusuha doesn't get kidnapped in any way, even when she's not the primary damsel (she was this in the first game, then Excellen takes the mantle for the sequel, which gets passed back to Kusuha in ''Original Generation Gaiden'', along with Lamia). Note all three get {{brainwashed}} in the kidnappings, too. Kusuha gets another non-brainwashed edition in ''2nd Original Generation'', but this is easily missed (mainly, she gets into this situation ''with'' Bullet and Shine, only if you pick Lune's route to witness it, otherwise there's no implication), and it's probably the last time she ever does so, as ''Alpha 2'' plot kicks in and she starts picking up main competence and prominence afterwards.
* DivergentCharacterEvolution: Kusuha and Bullet may be the recurring stars of ''Alpha'', but the other six ''Alpha'' originals get a fair share of the spotlight here. Likewise, the ''Alpha 2'' and ''MX'' protagonists get their back-stories expanded exclusively for ''Original Generation''.
* DroppedABridgeOnHim: In a twist for the ''Second Original Generation'', [[spoiler:all non mass-produced Huckebeins are destroyed by [[Characters/SuperRobotWarsOriginalGeneration Amara Balshem]] with the "Code:Evil" on orders from [[Characters/SuperRobotWarsOriginalGeneration Arteil Steinbeck]], who wants the Huckebein series to disappear. Dialogue notes they're still in a repairable state, but that doesn't happen in this game. The [=EX-EXbein=] is essentially created using parts from the destroyed units to repair the damaged Ashe]].
* EarlyBirdCameo: [[spoiler:[[Characters/SuperRobotWarsAlpha Cobray Gordon]]]] in ''Original Generations'' and [[spoiler: the ''MX'' originals and Touma]] in ''Original Generation Gaiden''.
** ''Divine Wars'' establishes a few characters were present during the Divine Crusaders War before their appearance into ''Original Generation 2'':
** [[Characters/SuperRobotWarsAlpha Ibis Douglas and Sleigh Presty]] are test flying Armored Modules during Tenzan's debut in the field.
** Although [[Characters/SuperRobotWarsOriginalGeneration Colonel Van Vat Tran]] is formally introduced in the sequel as leader of the Neo Divine Crusaders, he appears as one of the headlining officers present when Bian declares war on TheFederation.
** As the Aerogaters begin their invasion, [[Characters/SuperRobotWarsAlpha Yuuki Jaggar and Ricarla "Carla" Borgnine]] are seen as a Divine Crusaders pilot and evacuating civilian, respectively.
** [[spoiler:Cobray does so ''again'' in ''The Moon Dwellers''... as his original Balmar identity Ayin. How it solves the whole 'there is only one Time Diver' thing with the original Cobray is yet to be seen.]]
* EpicFail: As a MythologyGag to ''Alpha Gaiden'', certain attacks in the ''Second Original Generation'' has special animations that play if [[http://www.youtube.com/watch?v=6VrMHd1_lDg the attacking unit misses]].
* EvilKnockoff: During Ryusei's route in ''Original Generation'', upon entering the White Star, [[spoiler:copies of a majority of allied units in the party are part of enemy reinforcements]]. In ''Original Generation 2'', the Einst make a knockoff of Kyosuke's Alt Eisen called the "Einst Eisen", while [[spoiler:[[Characters/SuperRobotWarsOriginalGeneration Beowulf]]]] in the final episode of ''The Inspector'' creates copies of the Cybuster, SRX and Grungust.
* {{Exposition}}: Tons of it, largely of characters in enemy factions discussing matters that helps the player understand some of the things going on, or to give them a reason to ''really'' hate them. Smarter players will be able to figure out quite a bit, due to loads of dropped hints.
* {{Expy}}: While some characters share characteristics of many protagonists of licensed shows, the originals get expies of their own ''for'' licensed shows, with [[MagicalGirlLyricalNanoha Signum]] referencing Lamia being the best example. ''Endless Frontier'' plays this up with multiple characters being offshoots of their main continuity counterparts, while many of the Shura in ''Original Generation Gaiden'' are essentially disciples of [[FistOfTheNorthStar Hokuto Shinken]].
* FaceHeelTurn: Can't have an [=SRW=] without one or two of these.
** HeelFaceTurn: ...or six or seven of these. Justified as a means to increase the number of characters in the party.
* GagBoobs: Much has been made of the girls' chest sizes, of which Seolla's becomes a plot point [[InsultedAwake in order to break her brainwashing]], but ''Endless Frontier'' is probably king (or, "queen", perhaps?) of this trope and lampshading thereof, ''so'' much that [[ImageBoard 4chan's /m/]] has long known it as "Oppai Saga: Endless Tits" or any of a dozen such variations.
* GaidenGame: ''Original Generation Gaiden'', ''Dark Prison'', the entire ''OG Saga'' line and ''[[AnotherCenturysEpisode Another Century's Episode: R]]'' (due to three characters from this continuity appearing there)
* GameMod: "[[http://www.mediafire.com/?57rci82r1116rno Super Robot Wars Original Generation 2 Ver. A]]", a heavily-modified ''Original Generation 2'' which explores [[ForWantOfANail what would have happened if]] [[Characters/SuperRobotWarsAdvance Axel Almer]] [[AmnesiacDissonance had gotten amnesia]] and aligned with the heroes. Deviations from canon include characters starting off with different mecha, additional {{Leitmotif}}s to pre-existing characters and a change to the FinalBoss.
** ''[[http://www.youtube.com/watch?v=iHD43dOhEME Gouka/Gorgeousness Version]]'' adds playable units from the first game that weren't available for the sequel, new units from other [=SRW=] Gameboy Advance titles and additional {{Leitmotif}}s.
* GameplayAndStorySegregation: Like other [=SRW=] installments, players can switch characters from one unit to another, despite certain mecha being exclusive to a character. In the ''Second Original Generation'', attacks for the ''Masou Kishin'' units can be unlocked when they shouldn't be able to at that point in the story. WordOfGod says this is due to RuleOfFun, but also to avert CantCatchUp.
* GotMeDoingIt: You'll see one character use gambling metaphors before and during battles and another's {{otaku}}ness and tendency to CallingYourAttacks rubbing off on his allies in the sequels. It's gotten to a point the developers decided nearly every allied character's required to do this when [[http://www.youtube.com/watch?v=ISQIKZTr5d4 performing]] [[http://www.youtube.com/watch?v=m-EmFkf-jUk a]] [[http://www.youtube.com/watch?v=B3zJCj0l5lk certain]][[http://www.youtube.com/watch?v=E1Whnv2KS2o attack]].
* {{Gratuitous Foreign Language}}s
* GuideDangIt: You can earn major bonuses, including a couple of {{Disc One Nuke}}s, by completing certain levels in certain ways. It's not so bad when the condition is "Get X kills with a certain character", but there are others, such as finishing the intro level for a MidSeasonUpgrade without the pilot scoring any kills with the upgrade, for example. The worst, though, is found in ''Original Generation 2'', where a supposedly {{Unwinnable}} scenario with a QuirkyMinibossSquad having end-game statistics requires you to flee, but if players stick around to defeat them, it results in getting some of the best weapons and parts in the game fifteen scenarios in. It's entirely possible, especially if the player scored an earlier GuideDangIt special weapon that shows up on this mission; the trick is to lure the QuirkyMinibossSquad in and abuse the massive terrain effects granted by the White Star to survive their attacks.
** Getting a certain equippable weapon in the ''Second Original Generation'' involves using a specific character with no plot relevance in any of the previous games, to achieve a certain number of kills by a point in a playthrough, then destroy a set number of {{mook}}s in a particular scenario, ''including'' the boss for that stage. The reason this was such a GuideDangIt for a long time was due to players simply assuming the weapon was only available at the start of "Special Mode", even when most secrets can be unlocked during the course of a normal playthrough.
* HarderThanHard: Aside from earning "Battle Masteries" to increase difficulty, an additional "EX-Hard" mode upon completion lets players face tougher enemies on a second run, with restricted or outright locked options for upgrading units and pilots.
* {{Hotblooded}}: Naturally, as per [=SRW=]; hilariously done over the top for some characters inside [[http://www.youtube.com/watch?v=8FBYA4P7NDw&fmt=18 a particular unit]].
* HumansAreSpecial: One of the primary reasons why extraterrestrials keep coming to Earth is humanity's skill in "mastering alien technology in a short time". For some of the aliens, like the Aerogaters, Earthlings make good CannonFodder. [[spoiler:Subverted in the ''Second Original Generation'' as the aliens aren't coming here because of us, but because of the Granzon]].
* HumansAreTheRealMonsters: The Inspectors and Einst describe the Earthlings as this, though the former ([[HonorBeforeReason except one]]) are a bunch of arrogant {{Hypocrite}}s.
* [[HumongousMecha Humongous]] [[CombiningMecha Combining]] and/or [[TransformingMecha Transforming]] [[RealRobot Real]] and {{Super Robot}}s: ''Doy''.
* [[IdiosyncraticEpisodeNaming Idiosyncratic Sequel Naming]]: Though this wasn't a problem at first, it cropped up thanks to ''Original Generation 2'' and the ''Second Original Generation''. See, sequels in major [=SRW=] continuities are traditionally called "Dai-#-ji Super Robot Wars (continuity name)"; the number denotes what chapter the series is in. ''Original Generation 2'' wasn't - it was ExactlyWhatItSaysOnTheTin in English, even in Japan. This raised a few eyebrows but nobody thought much of it, until both games were compiled into ''Original Generation'''s'''''. At this point, Banpresto seems to have treated ''Original Generations'' much like they previously did with the ''Compact 2'' trilogy regarding ''Impact'' - that BOTH Game Boy Advance titles are simply "parts one and two" of the "FIRST" ''Original Generation''. Since ''Original Generation Gaiden'' is...well, a GaidenGame, when the "proper" sequel came out, it's stylized as "Dai-2-ji Super Robot Wars Original Generation". The end result is two games with a "2" in their title and a decent amount of confusion in Japan and internationally; in other words, the Gameboy Advance game is typically referred to as ''Original Generation 2'', while the [=PlayStation=] 3 title is the ''Second Original Generation''.
* LoadsAndLoadsOfCharacters: 'Natch, though by the ''Second Original Generation'', the cast listing extends beyond simply playable pilots and enemy characters to {{Non Player Character}}s that may or may not have plot significance. Granted, [=SRW=] is no stranger to having tons of characters.
* LovecraftLite: Two factions of {{Sufficiently Advanced Alien}}s want to enslave the Earth, {{Eldritch Abomination}}s are abound (one considers Earthlings a failure and want to "reset it", [[MultiversalConqueror one]] is searching for a McGuffin in this world and won't mind destroying it just to get it, another feeds on humanity's despair and [[OmnicidalManiac one wants everything destroyed, period]]), [[AIIsACrapShoot two systems programmed to protect humanity turn against them]], no thanks to their MadScientist creators, and a guardian god of the Earth turns into a WellIntentionedExtremist. While it's likely there are future threats to appear down the line, the BadassArmy is capable of [[DidYouJustPunchOutCthulhu beating them all]].
* MassiveMultiplayerCrossover: ''Original Generation'' is basically [=SRW=] crossed over with ''itself''.
* MassOhCrap: In ''Dark Prison'', [[spoiler:after Shu and his party frees [[Characters/MasouKishin Saphine Grace]] from the influence of [[Characters/MasouKishin Shiva Volkruss]], the dark god attempts to possess Shu and the Granzon. This leads to his party reacting appropriately, especially when Shu's machine transforms into the [[StoryBreakerPower Neo Granzon]]. Fortunately, Shu's response averts this]].
---> '''Shu''': "[[spoiler:[[HellYesMoment I've]] [[BadassBoast won]]...[[CrowningMomentOfAwesome Volkruss]]]]."
* MightMakesRight: Some generic {{Mook}}s you fight, sans AIs like simulation troops and Aerogaters, sometimes say "The one who has strength is right!" upon attacking.
* MinMaxersDelight: The "SP Regeneration" and "Attacker" pilot skills become an obligatory set for characters. After being removed as purchaseable skills and becoming character-exclusive, those who do get it are considered invaluable, some even borderline GameBreaker.
* MoodWhiplash: ''Original Generation Gaiden'' provides one, in particular a segment of Ryusei and [[Characters/SuperRobotWarsAlpha Mai Kobayashi]] gaining a CombinationAttack, which is then followed by [[spoiler:the return of the [[Characters/SuperRobotWarsOriginalGeneration ODE System]] and a surviving Lamia at its helm once again, no thanks to [[Characters/SuperRobotWarsReversal Duminuss]] trying to completely demoralize the team]]. Kyosuke goes through another HeroicBSOD...and then we switch into [[Characters/SuperRobotWarsAlpha Raidiese F. Branstein]] getting fed up on Ryusei's CallingYourAttacks tendencies and ''[[ShoutOut Galaxy]] [[SaintSeiya Phantom]] [[NotSoAboveItAll Explosion]]''.
* MsFanservice: Undoubtedly Excellen, although [[Characters/SuperRobotWars Garnet Sandi]] could very well be the other, until she's PutOnABus. Carla tries to invoke this in the sequel, but is vastly overshadowed by Seolla. Many of the other girls fulfill their fair share, as does [[VideoGame/SuperRobotWarsMX Aqua Centrum]] and Cliana for the ''Second Original Generation''. In fact, the latter two are pushed as the new primary MsFanservice through promotion.
* MilitaryMaverick: Averted; despite the cast being a collection of {{Hotblooded}} {{Bunny Ears Lawyer}}s, they still follow the chain of command (even those not affiliated with the military), even if they have qualms about the higher ups.
* MythologyGag: The save-quit dialogues are full of this and NoFourthWall (see below). Some of note are [[Characters/CompatiHeroSeries Gilliam Yeager and Dark Brain]] talking about dodgeball[[note]]Both characters being playable in ''Battle Dodgeball''[[/note]], Kusuha asking Bullet if he's going to wear a black mask[[note]]Bullet pulling a FaceHeelTurn in ''Alpha 2'' via BrainwashedAndCrazy, wearing a black mask[[/note]], and Lamia asking Axel why he doesn't act goofier[[note]]Axel's personality trait as the heroic protagonist in ''Advance''[[/note]].
* {{Nerf}}: This has been an occurence since the series was rebooted and remade into ''Original Generations'', with ''Original Generation 2'' doing such things as reducing the effectiveness of {{Combination Attack}}s (particularly Rampage Ghost). The ''Second Original Generation'' goes whole hog with making various pilot skills becoming unpurchaseable and rare among the roster, reducing terrain/weapon rankings and having characters learn damage-buffing Spirit Commands as their last available. Of course, some players argue these are offset with Maximum Break and the introduction of the "Ability Slot System".
* NiceJobFixingItVillain: Several times in the games, but justified as many of things the villains do to further their own ends end up being beneficial to the heroes more than them.
* NoFourthWall: At least in the localization, the Inspectors are prone to [[BreakingTheFourthWall breaking it]]. When you beat them in the supposedly unbeatable scenario, one stays silent at the predicament, then mutters "Good job." ''Original Generations'' adds this further in one save-quit dialogue, where Gilliam ends up promoting ''Hero Senki'', the game where he made his debut, and Shu lying about "saving more times will increase game difficulty". Not to be outdone by the games, in one episode of ''The Inspector'', a villain [[http://img201.imageshack.us/img201/5315/4thwall.jpg grabs the edge of the frame with a hero in it]] and pushes it off the screen in frustration.
* OrdinaryHighSchoolStudent: Beginning with ''Original Generation Gaiden'', this trope starts to repeatedly occur as opposed to using military personnel to fill the roster - [[Characters/SuperRobotWarsOriginalGeneration Kouta Azuma and his sister Shouko]] until they got their respective PoweredArmor, [[Characters/SuperRobotWarsOriginalGeneration Michiru Hanaten]] in the ''Second Original Generation'' and Touya in ''The Moon Dwellers''.
* OriginalGeneration: TropeNamer and possibly TropeCodifier in fiction due to its sheer numbers.
* PeninsulaOfPowerleveling: One scenario in the ''Second Original Generation'', due to an infinite number of respawning {{mook}}s, at the cost of one Battle Mastery. While this serves as an advantage for the rest of a playthrough, it's possible to backfire if the player overabuses this by destroying too many of them (the game will freeze if left unattended).
* ThePowerOfLove: And what a power! Event-driven scenarios with {{Battle Couple}}s uses this to extremes.
* PutOnABus: Inevitably, some characters get backlined, otherwise there would be too much in one game the game couldn't handle it:
** Both Giado Venerdi and Garnet Sandi retired from the frontlines effectively after the Divine Wars, with both of them married and having children.
** Folka Albark and the rest of the surviving Shuras went on a journey to discover a new home for the Shuras after the battle with Dark Brain, and they have yet to return.
** In spite of the Masou Kishin cast somehow making its return in ''Moon Dwellers'', only the main trio (Masaki Andoh, Lune Zoldark and Shuu Shirakawa) along with Saphine and Amara return from La Gias, Huang Yang Long, Tyutti Noorbucks and Mio Sasuga apparently still stayed at La Gias.
** Since ''VideoGame/ProjectXZone'' is considered canon to this timeline, counting on Haken and Sanger's POV, that means this happens to [[VideoGame/EndlessFrontier Kaguya Nanbu]] who stayed at her home dimension (when she was the one accompanying the two during the crossover) while both Haken and Aschen went into their origin home.
* PretextForWar: When Shu fires a Black Hole Cluster at the Shirogane, this is when Bian Zoldark forms the Divine Crusaders and started a war with the EFA [[spoiler: so that the EFA can get a wake up call and figure out that they have the firepower and the manpower to fight against any alien invasion.]] Unfortunately, as revealed in ''Dark Prison'', [[spoiler: Albharda's girlfriend was in the Shirogane and it was supposed to be a day one flight voyage for her. This is his primary motivation for wanting to enact "Mission Devil" which means, "find the Neo Granzon and if Shu is using the Neo Granzon, kill him."]]
* PsychicLink: The "T-Link" and "Sympathia" Systems. The former powers up machines and weaponry in addition to amplifying a Psychodriver's powers which draws other telekinetic users closer. Sympathia acts in a similar way, but allows a direct link to the machine equipped with the system, making it an extension of the pilot, but it also chooses who can and cannot pilot the unit it's equipped with, and gives a telepathic link to others who have the system. [[spoiler:However, using the Sympathia System comes with a price, as overuse may erode the pilot's soul, transplanting another one into their body]].
* RammingAlwaysWorks: The bog-standard/last-ditch melee attack used by Gespensts is a mecha-sized shoulder charge. There's also the enhanced ramming Sonic Breaker attacks used by Lion variants. Finally, the ''Kurogane'' battleship with a [[ThisIsADrill giant drill attached to its bow]], making it a viable attack.
** As the anime adaptations have shown repeatedly, '''DO NOT''' attempt to invoke this trope against the Cybuster. The Elemental Lord of the Wind's "Akashic Buster" '''WILL''' out-ram anything
* RecursiveCanon: At the end of ''Divine Wars'', Ryusei buys a Gespenst [[TheMerch model kit]].
* RelationshipValues: Played straight with the gameplay. Characters placed adjacent to allies they are [[ThePowerOfFriendship friends with]], [[RivalsTeamUp rivals]] or [[ThePowerOfLove show a degree of affection]] (even if it's ''not'' reciprocated) get accuracy, evasion and damage bonuses. Naturally, {{Combination Attack}}s are this.
* RetCon: ''Original Generations'', being in and of itself a VideoGameRemake of the Gameboy Advance titles, [[CanonDiscontinuity does this]]. To wit:
** Units from the first game are still playable in ''Original Generation 2'', then carried over to ''Original Generation Gaiden''.
** Several characters originally KilledOffForReal manage to stick around.
** Axel turning from a {{jerkass}} in ''Original Generation 2'' to a NobleDemon in ''Original Generations'', [[spoiler:eventually [[HeelFaceTurn turning face]] in ''Original Generation Gaiden'']].
* RuleOfCool: The games practically run on this.
* ScrewThisImOuttaHere: More often that not in this series, boss characters will flee if their unit's HitPoints threshold reaches a certain minimum. In order to earn some Battle Masteries, the player must ensure these boss units' HP reaches zero, without surpassing that threshold.
* ShoutOut
** In ''The Inspector'', the two pilots of Aguila's [[Anime/{{Gravion}} Sol Gravilion]] are basically [[Anime/{{Gravion}} Touga Tenkuji and Eiji Shigure]] with different hair colors. In an earlier episode, a ''Shirogane'' BridgeBunny looks exactly like one of the ''Anime/{{Gravion}}'' {{Meido}}.
** The "one more hit" lines in ''The Inspector'' are obviously a shout to the gameplay, where after doing numerous powerful attacks, the player still finds himself needing to execute one more attack to finish off the opposing unit. [[spoiler:The finale lampshades it some more when the heroes split into smaller groups, fighting each Einst doppelganger]].
** One of the save-quit conversations in ''The Moon Dwellers'' has [[Characters/SuperRobotWarsJudgment Touya and Katia]] reference [[Manga/DaimidalerTheSoundRobot the Hi-Oru particles.]] [[ActorAllusion Bonus points for]] [[Creator/NobunagaShimazaki the same]] [[Creator/YokoHikasa seiyuu reference.]]
* SmugSnake: Though one would expect the villains to play this straight, a few from TheFederation also do this.
* SparedByTheAdaptation: Mostly those who pull a HeelFaceTurn get this, while a few survive from PlotArmor. Inverted in the ''Second Original Generation'', where one character who pulled a HeelFaceTurn ends up taking the job to defeat one of the BigBadEnsemble.
* SpoilerOpening: The opening credits for ''The Inspector'' introduce numerous new characters before their actual appearance, spoiling what could be surprises. Justified, as people most likely to watch the show are the ones who've already played the games.
* StealthMentor: ''Original Generation'' loves this; [[spoiler:practically every villain]] in the first game follows this.
* StoppedNumberingSequels: ''The Moon Dwellers''; by WordOfGod, this is so newcomers won't be deterred by the game being the next major installment of the series and can still play it without foreknowledge of previous events.
* SuperMovePortraitAttack: Banpresto claimed the number of pilot cut-ins in ''Original Generations'' was one of the largest ever assembled...and they delivered, since even the most basic attacks necessitated cut-ins.
* ThemeNaming
* ThemeMusicPowerUp: Just like most [=SRW=] installments, FinalBoss battles will be accompanied by a song after in-game events. However, the ''Second Original Generation'' takes this further by including the actual JAMProject-related theme song to the respective game, rather than the instrumental cover version. In other words, you'll hear the full tune of "Victory" from ''MX'', "Skill" from ''Alpha 2'' and ''Wings of Legend'' for the ''Second Original Generation''. Note that this is the second time in franchise history players were given a full vocal rendition of a song; the first belongs to "[[Anime/SuperDimensionFortressMacross Do You Remember Love?]]" from the UsefulNotes/SegaDreamcast version of ''Alpha''.
* TitleDrop: In the first game, Ryusei claims that "Operation SRW" stands for "Super Robot War".
* {{Troperiffic}}: Not unique to this sub-series, but unlike the rest of the franchise, it doesn't have the excuse of being a crossover between the TropeMakers themselves. Still, is that any reason ''not'' to use as many as humanly possible?
* TrueFinalBoss: Done with the GameBoyAdvance titles, then averted via {{retcon}} by ''Original Generations''. The ''Second Original Generation'' returns this in full with a BiggerBad.
* UltimateUniverse: It's mostly a distillation of previous [=SRW=] continuities, without all the crossover elements.
* UnexpectedCharacter
** The rest of the ''Masou Kishin'' cast appearing on a console [=SRW=] again after 11 years since their last appearance in ''Alpha Gaiden''. What makes this long-awaited return unexpected was a lot of fans lost hope of that ever happening, and [[TeasingCreator Banpresto waited until the last moment to reveal this]]. Moreover, the ''Masou Kishin'' mecha gaining their final attacks as a secret, despite violating canon, adds to the unexpectedness.
** Savvy players knew the plot of [[spoiler:''VideoGame/SuperRobotWars4'']] would happen sooner or later, but no one expected the [[spoiler: [[Characters/SuperRobotWarsClassic Guests of the Zuvorg Alliance]]]] to appear in the ''Second Original Generation''. All [[spoiler: Guests]] characters are present, including [[spoiler:a certain Inspector who comes BackFromTheDead]].
** For ''Alpha'' players, it's obvious the [[spoiler:[[Characters/SuperRobotWarsAlpha Nashim Gan Eden]]]] would appear, as the Custos of the Garden of Baral were seen in promotional trailers. What players ''didn't'' expect was Kukuru and her Magalga from ''Alpha 2'' appearing alongside the returning Youkijin; in fact, players pretty much forgot about Kukuru after ''Alpha 2''. [[spoiler:Son Ganlong]] is also present as one of the late-game bosses, but rather than the [[spoiler:Shin [=RyuOhKi=]]] from ''Alpha 3'', players are treated to the [[spoiler:[=OuRyuOh=]]].
** Somehow, Banpresto gave a little love to ''Super Hero Operations'' by including new character Arteil Steinbeck, [[spoiler:a clone {{Expy}} of [[Characters/SuperRobotWarsAlpha Euzeth Gozzo]], who turns out to be Euzeth himself, having masterminded all the current events in ''Original Generation'' continuity. Instead of the [[PaletteSwap Black Judecca]] from ''Alpha'', Euzeth uses the new "Adamatron", a clever MythologyGag to the Chojin Zest from ''Super Hero Operations'']].
** Michiru Hanaten is a [[JapaneseDelinquents delinquent]] loosely mentioned in the ''Endless Frontier EXCEED'' drama CD, and appears in the ''Second Original Generation'' to challenge Kouta to a fight. He has since achieved instant EnsembleDarkhorse status [[spoiler:when he becomes [[http://www.youtube.com/watch?v=LCtJ-3Fxh5g playable in the game with his own mecha]]]].
** Haken and Aschen being present in ''The Moon Dwellers'' is not only a surprise, but will effectively bridge the gap between Haken and Sanger's appearance from ''VideoGame/ProjectXZone'' and justify their abscence in the sequel.
* WakeUpCallBoss: [[spoiler:[[Characters/SuperRobotWarsClassic Bian Zoldark]] and the Valsion alongside Shu and the Granzon and Ingram with the R-Gun Rivale]], thanks to their machines incorporating barriers and HP/EN regeneration. These kind of bosses are the type to expect down the line in later scenarios of the first game.
** Ironically, [[FridgeBrilliance this is what was intended from the beginning]], which shows how savvy [[spoiler:Bian]] really is.
** For some people, [[spoiler:[[Characters/MasouKishin Feilord Grania Bilseia and his Duraxyll]]]] in the ''Second Original Generation'' is this thanks to having the "Zeal"[[note]]Gain an additional turn (self)[[/note]] Spirit Command early in the game plus very powerful attacks.
** In ''Dark Prison'', [[spoiler:[[Characters/SuperRobotWarsClassic Thomas Platt]] and his Guarlion]] for players who want to obtain the SR Point and any goodies dropped. Rather than counterattack, the boss will defend[[note]]Defending halves all damage taken[[/note]]; not even a Maximum Break is enough to destroy him. This teaches players to also rely on counterattack kills. The reason this is a wake-up call is it occurs as early as the third scenario, when players barely have any credits for upgrades, as well as the SR Point requirements becoming harder to achieve from this point on.
* WeaponOfChoice: Exclusively to ''Original Generation'', all {{Real Robot}}s can be mounted with a limited number of extra weapons and modules used all around by other reals.
** DamageIncreasingDebuff: "Armor Breaker"
** EpicFlail: "Boost Hammer"
** KatanasAreJustBetter: "Shishioh Blade"
** KillSat: "Free Electron Cannon"
** LaserBlade: "Beam Sword", "Neo Plasma Cutter", "Roche Saber"
** ManaBurn: "Energy Taker/Energy Taker+", "Spirit Taker"
** PileBunker: "G-Impact Stake"
** PrecisionGuidedBoomerang: "Stealth Boomerang"
** RayGun: "Graviton Launcher", "Hyper Beam Cannon", "Hyper Beam Rifle S", "Magna Beam Rifle", "Photon Rifle/Photon Rifle S", "Twin Magna Rifle",
** RevolversAreJustBetter: "G. Revolver"
** RingsOfDeath: "Neo Chakram Shooter", "Slash Ripper", "T-Link Ripper"
** ShotgunsAreJustBetter: "M13 Shotgun"
** SniperRifle: "Boosted Rifle", "Burst Railgun"
* WeCannotGoOnWithoutYou: Although true to most [=SRW=] installments and scenario objectives, ''Dark Prison'' ascends this to an instant game over if ''any'' playable unit is destroyed in its scenarios. Justified as the party does not have access to a battleship.
* WeWillNotUsePhotoshopInTheFuture: Averted in the ''Second Original Generation'' where TheFederation knows the video released on the internet [[spoiler:regarding Arteil having a private conversation with [[Characters/SuperRobotWarsClassic Teniquette Zezenan]]]] is doctored and cannot be used as evidence against him. However, this is still AllAccordingToPlan.
* WorldOfBuxom: The art for the game reveals being nicely endowed is the norm and the only adult character getting called "flat" is around a B-cup. ''Endless Frontier'' takes this UpToEleven.
* YouBastard: A light example in the first game, where the things Tenzan comments he'll do are examples of what the player themselves can do within the games' mechanics, including the use of deliberately dying to restart a mission with increased {{Character Level}}s carried over, thus LevelGrinding your way to victory.
* ZergRush: Mostly averted, as enemy ratio is fairly reasonable, but at least one level in ''Original Generation 2'' fits this trope. In-universe, this is basically the only Einst tactic: it's even commented on by the characters.
